JAXWS/Tools Extension Points

Annotations Framework

Annotation Category

Plug-in: org.eclipse.jst.ws.annotations.core

Identifier: org.eclipse.jst.ws.annotations.core.annotationCategory

Description: The purpose of this extension point is to define an annotation category to group together a set of annotations.

Consumers org.eclipse.jst.ws.jaxws.core, org.eclipse.jst.ws.jaxb.core

Example: Defines a JAX-WS category.

<extension point="org.eclipse.jst.ws.annotations.core.annotationCategory">
   <category
      id="jaxws.category"
      name="JAX-WS">
   </category>
</extension>

Annotation Definition

Plug-in: org.eclipse.jst.ws.annotations.core

Identifier: org.eclipse.jst.ws.annotations.core.annotationDefinition

Description: This extension point is is used to define an annotation.

Consumers org.eclipse.jst.ws.jaxws.core, org.eclipse.jst.ws.jaxb.core

Example: Defines the javax.jws.WebService annotation.

<extension point="org.eclipse.jst.ws.annotations.core.annotationDefinition">
   <annotation
      category="jaxws.category"
      class="javax.jws.WebService"
      name="WebService">
   </annotation>
</extension>

Example: Annotations use ElementType constants with the Target meta-annotation type to specify where the annotation can be applied. This information is used by the JAX-WS Annotation Properties view when presenting applicable annotations for a selected element in the Java editor. One of those constants is the ElementType.TYPE constant which covers classes, interfaces and enum declarations. It's possible to further refine that restriction in the properties view using the optional restrictedTo attribute when defining the annotation.

<extension point="org.eclipse.jst.ws.annotations.core.annotationDefinition">
   <annotation
      category="jaxws.category"
      class="javax.xml.ws.WebServiceProvider"
      name="WebServiceProvider"
      restrictedTo="CLASS_ONLY">
   </annotation>
</extension>

Example: The @HandlerChain annotation specifies the TYPE, METHOD and FIELD ElementType as its applicable targets. However in JAX-WS 2.1 the @HandlerChain annotation may only be specified on a TYPE. The METHOD and FIELD element types were used in JAX-WS 2.0. To filter out the METHOD and FIELD element types so that the @HandlerChain annotation isn't presented for those selections in the JAX-WS Annotation Properties view we can use the targetFilter attribute when defining the annotation.

<extension point="org.eclipse.jst.ws.annotations.core.annotationDefinition">
   <annotation
      category="jaxws.category"
      class="javax.jws.HandlerChain"
      name="HandlerChain">
      <targetFilter target="FIELD"/>
      <targetFilter target="METHOD"/>
   </annotation>
</extension>

Annotation Initializer

Plug-in: org.eclipse.jst.ws.annotations.core

Identifier: org.eclipse.jst.ws.annotations.core.annotationInitializer

Description: This extension point is used to define an 'initializer' for an annotation which can used to calculate values for the annotations elements.

Consumers org.eclipse.jst.ws.jaxws.ui

Example: Adds an initializer for the javax.jws.WebService annotation.

<extension point="org.eclipse.jst.ws.annotations.core.annotationInitializer">
   <initializer
      annotation="javax.jws.WebService"
      class="org.eclipse.jst.ws.internal.jaxws.ui.annotations.initialization.WebServiceAttributeInitializer">
   </initializer>
</extension>

Annotation Processor

Plug-in: org.eclipse.jst.ws.annotations.core

Identifier: org.eclipse.jst.ws.annotations.core.annotationProcessor

Description: This extension point is used to define a APT 'processor' which is used to validate the annotation.

Consumers org.eclipse.jst.ws.jaxws.core

Example: Adds a processor to validate a subset of the rules pertaining to the javax.jws.WebService annotation.

<extension point="org.eclipse.jst.ws.annotations.core.annotationProcessor">
   <processor
      annotation="javax.jws.WebService"
      class="org.eclipse.jst.ws.internal.jaxws.core.annotations.validation.WebServicePublicAbstractFinalRule">
         <description>
            Classes annotated with @WebService must be an outer public class, must not be final, and must not be abstract
         </description>
   </processor>
</extension>

Web Service Domain Object Model

Contributing web service model runtime extension

Plug-in: org.eclipse.jst.ws.jaxws.dom.runtime

Identifier: org.eclipse.jst.ws.jaxws.dom.runtime.domruntimes

Description: This extension point is used to contribute artifacts in the web service domain object model. The contributed artifacts are visible under the "JAX-WS Web Services" node in the Project Explorer view

Consumers org.eclipse.jst.ws.jaxws.dom.runtime

Example: Adds a WS DOM runtime extension for JAX-WS web services contained in EJB3.0 / Web2.5 module projects

<extension
    id="org.eclipse.jst.ws.jaxws.dom.jee5" 
    name="JEE5 DOM contribution"
    point="org.eclipse.jst.ws.jaxws.dom.runtime.domruntimes">
  <implementation class="org.eclipse.jst.ws.jaxws.dom.runtime.persistence.Jee5WsDomRuntimeExtension"/>
  <project_facet id="jst.ejb" version="3.0"/>
  <project_facet id="jst.web" version="2.5"/>
</extension>
