Ejb tags
Applies to: All EJB types on class, method and field level.
Defines information about the expected configuration properties of the message-driven bean in its operational environment. The properties that are recognized for a particular message-driven bean are determined by the messaging type. The following activation-config-properties are automatically generated from the corresponding parameters in ejb.bean and do not require a ejb.activation-config-property tag: acknowledgeMode, messageSelector, destinationType, subscriptionDurability. Only applicable to EJB 2.1 message-driven beans.

| use-soft-locking | bool | Entity beans |
If true, then generate a public int
version attribute in the auto-generated
concrete class, to form a optimistic
locking mechanism. The value of version
attribute is incremented in ejbStore.
Note: It's applicable to both CMP and BMP, but many containers have optimistic locking
capabilities built-in, so you don't need to worry about it locking issues.

Alternatively, the value may be composed of a path name specifying a Deployment File containing the referenced message destination with the message-destination-name of the destination appended and separated from the path name by "#". The path name is relative to the Deployment File containing Deployment Component that is referencing the message destination. This allows multiple message destinations with the same name to be uniquely identified.

| remote-business-interface | text | Session and Entity beans | Defines the remote business interface for the bean. If present, ejb.interface-method tags are not required, instead the remote interface will extend the business interface. The business interface must declare all methods as throwing RemoteException as per the business interface pattern. The generated techinical bean class (with thesession, entitycmp or entitybmp subtask) implements this interface (Business Interface Pattern). | false |
| local-business-interface | text | Session and Entity beans | Defines the local business interface for the bean. Similar to remote-business-interface, but the interface does not need to declare RemoteException in the throws clause. The generated techinical bean class (with the session, entitycmp or entitybmp subtask) implements this interface (Business Interface Pattern). | false |
| impl-class-name | text | All EJB Types. | Provides the fully qualified classname of the bean's implementation class, to be used in the ejb-class element of the ejb-jar.xml deployment descriptor. Its value is only used when the implementation class is not being generated by a subtask (e.g. <session/>, <entitycmp/>, ...) as those subtasks have other ways to determine the classname. This parameter is mainly intended to be used where the bean class itself is generated, and additional code is to be added in a subclass. | false |
| service-endpoint-business-interface | text | Session beans | Defines the service-endpoint business interface for the bean. Similar to remote-business-interface. | false |

| impl-jndi | text | Indicates a JNDI environment reference which will contain a String that is the fully qualified name of a class implementing the DAO interface. If present, the generated code for obtaining a DAO will look up this reference, then create a new instance of the class whose name is found there. This allows the actual implementation class to be determined at runtime. | false | |
| impl-factory | text | The fully qualified name of a factory class which can create DAO instances. If present, the generated code for obtaining a DAO will call a static method getDaoInstance(Class) on this class, which should return an object of the type specified in the class parameter. The call passes in the class to the getDaoInstance method in order to allow a single factory class to be used for multiple DAOs. | false | |
| create-methods | text |
Indicate if create methods should be automatically
included in the DAO interface.

of a destination with its consumers.
Default value(s): Valid options are: Consumes Produces ConsumesProduces Default value(s): Produces | false | |
| link | text | Used to link a message destination reference to a message destination. The Assembler sets the value to reflect the flow of messages between producers and consumers in the application. The value must be the message-destination-name of a message destination in the same Deployment File or in another Deployment File in the same J2EE application unit. Alternatively, the value may be composed of a path name specifying a Deployment File containing the referenced message destination with the message-destination-name of the destination appended and separated from the path name by "#". The path name is relative to the Deployment File containing Deployment Component that is referencing the message destination. This allows multiple message destinations with the same name to be uniquely identified. | false |
Defines an EJB reference to a bean which will be packaged in a different ejb jar file. For field-level tags, the Home-Interface is automatically looked up and assigned to the field before setSessionContext, setEntityContext or setMessageDrivenContext is called when generating the technical bean with the session, entitybmp, entitycmp or mdb subtask. Therefore, the field must have the protected access modifier. The tag may also be used on abstract methods which return the Home-Interface. Those methods are implemented in the object generated by the session, entitybmp, entitycmp or mdb subtasks. The implementation performs a caching for the value.
Applies to: Applicable to all types of EJBs.
| Parameter | Type | Applicability | Description | Mandatory |
|---|---|---|---|---|
| view-type | text | The view type that the reference uses. Valid options are: local remote Default value(s): remote | false | |
| link | text | Defines an ejb-link to the referenced EJB. The value of the ejb-link element is the name of the target enterprise bean.

The target enterprise bean can be in any ejb-jar file in the same J2EE application as the referencing application component. | false | |
| jndi-name | text | The referenced bean's physical JNDI-Name. | false | |
| ref-name | text | The name that the referenced bean will be referred to by. For example, to refer to the bean Customer as java:comp/env/ejb/Customer name should be ejb/Customer. Mandatory for class-level tags. For field- and method-level tags, the default value is the method or field name. | false. | |
| ejb-name | text |
The name that the referenced bean will be referred to
by. For example, to refer to the bean Customer as
java:comp/env/ejb/Customer name should be
ejb/Customer. Deprecated. Use ref-name instead.

Defines an EJB-reference to the bean with EJB-name [ejb-name]. ref-name is optional and if not specified then the reference name is [ejb-name] for remote references and [ejb-name]Local for local references. Attention: you have to import the referred class (the ejbdoclet one) even your EJB does not need it. For field-level tags, the Home-Interface is automatically looked up and assigned to the field before setSessionContext, setEntityContext or setMessageDrivenContext is called when generating the technical bean with the session, entitybmp, entitycmp or mdb subtask. Therefore, the field must have the protected access modifier. The tag may also be used on abstract methods which return the Home- or Component-Interface type. Those methods are implemented in the object generated by the session, entitybmp, entitycmp or mdb subtasks. The implementation performs a caching for the Home-Object. If the method's return type is the Component-Interface, create() is invoked to return the EJBObject. This is usefull for references to stateless session beans.
| Parameter | Type | Applicability | Description | Mandatory |
|---|---|---|---|---|
| ejb-name | text | The name of the EJB being referenced. | true | |
| view-type | text | The view type that the reference uses. Valid options are: local remote Default value(s): The referenced bean's view type if the referenced bean has either view-type 'local' or 'remote'. 'remote' if the referenced bean has view-type 'both'. | false | |
| ref-name | text |
The name that the referenced bean will be
referred to by. For example, to refer to the bean
Customer as java:comp/env/ejb/Customer name
should be ejb/Customer.
Default value(s): Class-level tags: ejb/[ejb-name] for remote references an ejb/[ejb-name]Local for local references, where [ejb-name] is the name of the referenced bean. Method- and field-level tags: the method or field name. | false |
Defines a (web)service reference for an EJB. This is a EJB2.1 thing. For field-level tags, the service is automatically looked up and assigned to the field before setSessionContext, setEntityContext or setMessageDrivenContext is called when generating the technical bean with the session, entitybmp, entitycmp or mdb subtask. Therefore, the field must have the protected access modifier. The tag may also be used on abstract methods which return the servic-interface. Those methods are implemented in the object generated by the session, entitybmp, entitycmp or mdb subtasks. The implementation performs a caching for the value.

Defines an environment entry for an EJB. For field-level tags, the env-entry's value is automatically looked up and assigned to the field before setSessionContext, setEntityContext or setMessageDrivenContext is called when generating the technical bean with the session, entitybmp, entitycmp or mdb subtask. Therefore, the field must have the protected access modifier. The tag may also be used on abstract methods which return the env-entry's value. Those methods are implemented in the object generated by the session, entitybmp, entitycmp or mdb subtasks. The implementation performs a caching for the value. If the field type or the method's return type is primitive, the env-entry is generated for the corresponding wrapper class and automatically converted during the lookup. Applicapable for the following field types and method return types: java.lang.Boolean, java.lang.Byte, java.lang.Character, java.lang.String, java.lang.Short, java.lang.Integer, java.lang.Long, java.lang.Float, java.lang.Double, boolean, int, byte, char, short, int, long, float, double

Definition for ValueObjects that follow the TransferObject pattern from http://java.sun.com/blueprints/corej2eepatterns/Patterns/TransferObject.html. ValueObjects can 'link' to other objects (of a relation) in two ways: aggregation and composition. Aggregation means that the other object is loosely coupled, while in Composition, the other object is 'embedded'. Note that aggregation and composition are mutually exclusive. See also http://xdoclet.sourceforge.net/xdoclet/valueobjects.html for more info.
Applies to: entity beans
| Parameter | Type | Applicability | Description | Mandatory |
|---|---|---|---|---|
| name | text | The name for this value object. The name will be used to form the generated class name. Using the default pattern, for example, if name is 'User', an 'UserValue' class will be generated. | false | |
| match | text | An identifier that can be used to select groups of attributes to be included in this value object. You can repeat this identifier in the method-level @ejb.value-object tag to add a property to a value object.

| extends | text | The name of the class the generated value object class should extend, if any. | false | |
| implements | text | A comma-separated list of interfaces the generated value object should implements, if any. Please note that XDoclet won't generate methods to implement these interfaces, so use this only if the interfaces doesn't contains any methods, or if the value object superclass (indicated in the 'extends' parameter) already implements all interface methods. | false | |
| ordering | text |
Alters the relationships between value objects. Strict ordering
requires that all primary key field in the object are java.lang.Comparable.
In return, the value object itself becomes java.lang.Comparable, and has
very well defined ordering and equality semantics. Strictly ordered objects
are only equal if they each have all their primary key fields set (even to null),
and each of these corresponding keys is equal. None indicates that
these objects can only be loosly compared. Equality is not as strictly defined,
and the objects are not java.lang.Comparable. When ordering is not strict, objects
are considered equal if and only if all of their members are themselves equal. In either
case the hashCode() is consistent with equals.
Valid options are: strict none Default value(s): none | false | |
| synchronization | text |
Indicates the level of synchronization of the value object.
Full synchronization is just what it sounds like, all methods are synchronized.
Partial synchronization indicates that only collections are synchronized.
None indicates that nothing is synchronized.
Valid options are: full partial none Default value(s): partial | false | |
| abstract | bool | Set if this value object is intended to be an abstract object which other value objects extend. | false | |
| generatePKConstructor | bool | Set if this value object should have a single argument constructor that sets the PK only. It's useful when using aggregation and you want to create a relationship between a new object and an existing object with the form of obj.addSomeObjectRelation(new SomeObject(pk)); | false |

Mark a persistent field containing a reference to another entity bean as being aggregated in this bean. The data object will contain accessor methods for the aggregated entity's data object instead of a reference to the entity itself. The aggregated entity will also be removed when this entity is removed. For example, aggregates are useful for sending graphs of data to the client. This is only applicable to entity beans and has no parameters.

For field-level tags, the Home-Interface is automatically looked up and assigned to the field before setSessionContext, setEntityContext or setMessageDrivenContext is called when generating the technical bean with the session, entitybmp, entitycmp or mdb subtask. Therefore, the field must have the protected access modifier. The tag may also be used on abstract methods which return the Home-Interface. Those methods are implemented in the object generated by the session, entitybmp, entitycmp or mdb subtasks. The implementation performs a caching for the value.
Applies to: Applicable to all types of EJBs.

Defines an EJB-reference to the bean with EJB-name [ejb-name]. ref-name is optional and if not specified then the reference name is [ejb-name] for remote references and [ejb-name]Local for local references. Attention: you have to import the referred class (the ejbdoclet one) even your EJB does not need it. For field-level tags, the Home-Interface is automatically looked up and assigned to the field before setSessionContext, setEntityContext or setMessageDrivenContext is called when generating the technical bean with the session, entitybmp, entitycmp or mdb subtask. Therefore, the field must have the protected access modifier. The tag may also be used on abstract methods which return the Home- or Component-Interface type. Those methods are implemented in the object generated by the session, entitybmp, entitycmp or mdb subtasks. The implementation performs a caching for the Home-Object. If the method's return type is the Component-Interface, create() is invoked to return the EJBObject. This is usefull for references to stateless session beans.

For field-level tags, the env-entry's value is automatically looked up and assigned to the field before setSessionContext, setEntityContext or setMessageDrivenContext is called when generating the technical bean with the session, entitybmp, entitycmp or mdb subtask. Therefore, the field must have the protected access modifier. The tag may also be used on abstract methods which return the env-entry's value. Those methods are implemented in the object generated by the session, entitybmp, entitycmp or mdb subtasks. The implementation performs a caching for the value. If the field type or the method's return type is primitive, the env-entry is generated for the corresponding wrapper class and automatically converted during the lookup. Applicapable for the following field types and method return types: java.lang.Boolean, java.lang.Byte, java.lang.Character, java.lang.String, java.lang.Short, java.lang.Integer, java.lang.Long, java.lang.Float, java.lang.Double, boolean, int, byte, char, short, int, long, float, double

The @ejb.persistence tag provides information about the persistence of a CMP Entity bean's fields. Use this for methods with the following patterns: public abstract Foo getX(); public abstract boolean isX(); public abstract void setX(Foo newVal); This will create the CMP field "X" in the generated CMP layer of type "Foo", and concrete implementations of the getX/setX methods. For BMP, it will generate getX/setX methods that keep track of a dirty flag (so that ejbStore is only called if necessary). If the type is boolean it is ok to have the get method prefixed "is" instead of "get". If you don't define the setter method, no setter method is generated for the concrete BMP/CMP class (concrete CMP class is generated only if EJB 1.1 or EJB 2.0 but using CMP 1.x). This is useful for cases where for example nothing is set programmatically but via external sources such as a stored procedure. Note that some application servers require jdbc-type and sql-type to be applied together to work correctly; have a look at the respective subtask for your application server.
Applies to: EJB entity bean fields. On the persistent fields getter methods.

| read-only | bool | Indicates that a field is read-only. | false |
Deprecated. Use the ejb.persistence tag instead.
Applies to: Methods which follow patterns: public abstract Foo getX(); public abstract boolean isX(); public abstract void setX(Foo newVal);
Use this for methods with the following pattern: public abstract Foo getX(). This will denote the persistent field "X" as a primary key field. The use of this tag requires that a primary key class is generated using the entitypk subtask. A primary key class must be used even if only one persistent field is marked with the ejb.pk-field tag. Must be used with the persistent-field tag. This tag is only valid for EntityBeans. It has no parameters.

Defines an EJB reference to a bean which will be packaged in a different ejb jar file. For field-level tags, the Home-Interface is automatically looked up and assigned to the field before setSessionContext, setEntityContext or setMessageDrivenContext is called when generating the technical bean with the session, entitybmp, entitycmp or mdb subtask. Therefore, the field must have the protected access modifier. The tag may also be used on abstract methods which return the Home-Interface. Those methods are implemented in the object generated by the session, entitybmp, entitycmp or mdb subtasks. The implementation performs a caching for the value.
Applies to: Applicable to all types of EJBs.
| Parameter | Type | Applicability | Description | Mandatory |
|---|---|---|---|---|
| view-type | text | The view type that the reference uses. Valid options are: local remote Default value(s): remote | false | |
| link | text | Defines an ejb-link to the referenced EJB. The value of the ejb-link element is the name of the target enterprise bean. (It is the name defined in the ejb-name element of the target enterprise bean.) The target enterprise bean can be in any ejb-jar file in the same J2EE application as the referencing application component. | false | |
| jndi-name | text | The referenced bean's physical JNDI-Name. | false | |
| ref-name | text | The name that the referenced bean will be referred to by. For example, to refer to the bean Customer as java:comp/env/ejb/Customer name should be ejb/Customer. Mandatory for class-level tags. For field- and method-level tags, the default value is the method or field name. | false. | |
| ejb-name | text |
The name that the referenced bean will be referred to
by. For example, to refer to the bean Customer as
java:comp/env/ejb/Customer name should be
ejb/Customer. Deprecated. Use ref-name instead.
Default value(s): ejb/[ejb-name], where [ejb-name] is the name of the referenced bean. | false | |
| type | text | The type of EJB being referenced. Valid options are: Entity Session | true | |
| home | text | The fully qualified class name of the home interface of the referenced bean. | true | |
| business | text | The fully qualified class name of the business interface (local or remote interface) of the referenced bean. | true | |
| remote | text | (Deprecated). Synonym for 'business' parameter. Only works if the view-type is 'remote'. | false |
Defines an EJB-reference to the bean with EJB-name [ejb-name]. ref-name is optional and if not specified then the reference name is [ejb-name] for remote references and [ejb-name]Local for local references. Attention: you have to import the referred class (the ejbdoclet one) even your EJB does not need it. For field-level tags, the Home-Interface is automatically looked up and assigned to the field before setSessionContext, setEntityContext or setMessageDrivenContext is called when generating the technical bean with the session, entitybmp, entitycmp or mdb subtask. Therefore, the field must have the protected access modifier. The tag may also be used on abstract methods which return the Home- or Component-Interface type. Those methods are implemented in the object generated by the session, entitybmp, entitycmp or mdb subtasks. The implementation performs a caching for the Home-Object. If the method's return type is the Component-Interface, create() is invoked to return the EJBObject. This is usefull for references to stateless session beans.
| Parameter | Type | Applicability | Description | Mandatory |
|---|---|---|---|---|
| ejb-name | text | The name of the EJB being referenced. | true | |
| view-type | text | The view type that the reference uses. Valid options are: local remote Default value(s): The referenced bean's view type if the referenced bean has either view-type 'local' or 'remote'. 'remote' if the referenced bean has view-type 'both'. | false | |
| ref-name | text |
The name that the referenced bean will be
referred to by. For example, to refer to the bean
Customer as java:comp/env/ejb/Customer name
should be ejb/Customer.
Default value(s): Class-level tags: ejb/[ejb-name] for remote references an ejb/[ejb-name]Local for local references, where [ejb-name] is the name of the referenced bean. Method- and field-level tags: the method or field name. | false |
Defines a (web)service reference for an EJB. This is a EJB2.1 thing. For field-level tags, the service is automatically looked up and assigned to the field before setSessionContext, setEntityContext or setMessageDrivenContext is called when generating the technical bean with the session, entitybmp, entitycmp or mdb subtask. Therefore, the field must have the protected access modifier. The tag may also be used on abstract methods which return the servic-interface. Those methods are implemented in the object generated by the session, entitybmp, entitycmp or mdb subtasks. The implementation performs a caching for the value.
Applies to: Applicatble to all EJB types with EJB-spec 2.1
| Parameter | Type | Applicability | Description | Mandatory |

Defines an environment entry for an EJB. For field-level tags, the env-entry's value is automatically looked up and assigned to the field before setSessionContext, setEntityContext or setMessageDrivenContext is called when generating the technical bean with the session, entitybmp, entitycmp or mdb subtask. Therefore, the field must have the protected access modifier. The tag may also be used on abstract methods which return the env-entry's value. Those methods are implemented in the object generated by the session, entitybmp, entitycmp or mdb subtasks. The implementation performs a caching for the value. If the field type or the method's return type is primitive, the env-entry is generated for the corresponding wrapper class and automatically converted during the lookup. Applicapable for the following field types and method return types: java.lang.Boolean, java.lang.Byte, java.lang.Character, java.lang.String, java.lang.Short, java.lang.Integer, java.lang.Long, java.lang.Float, java.lang.Double, boolean, int, byte, char, short, int, long, float, double

Defines a resource environment reference with the specified name and type. For field-level tags, the resource is automatically looked up and assigned to the field before setSessionContext, setEntityContext or setMessageDrivenContext is called when generating the technical bean with the session, entitybmp, entitycmp or mdb subtask. Therefore, the field must have the protected access modifier. The tag may also be used on abstract methods which return the resource's type. Those methods are implemented in the object generated by the session, entitybmp, entitycmp or mdb subtasks. The implementation performs a caching for the value.
