I'm pretty new to IBM WCM and IBM Portal; I'm using the following versions:

  • IBM WebSphere Portal Server_8.0.0.0
  • IBM Web Content Manager_8.0.0.0

I need to create a custom action for the WCM workflow; so far I was able in creating a very simple custom action by following this link: WCM Custom Action

Now I need to create a more complex custom action; in my custom action I would like to use spring 4.0 and Hibernate 4.3.0; so I created an EAR file and a WAR module; in my WAR module, under WEB-INF/lib directory I have the following jars:

  • commons-pool-1.5.4.jar
  • spring-beans-4.0.0.RELEASE.jar
  • hibernate-core-4.3.0.Final.jar
  • dom4j-1.6.1.jar
  • spring-aop-4.0.0.RELEASE.jar
  • validation-api-1.1.0.Final.jar
  • jandex-1.1.0.Final.jar
  • spring-context-support-4.0.0.RELEASE.jar

  • javassist-3.18.1-GA.jar
  • antlr-2.7.7.jar
  • aspectjweaver-1.7.4.jar
  • hppc-0.5.4.jar
  • commons-dbcp-1.4.jar
  • spring-jdbc-4.0.0.RELEASE.jar
  • hibernate-commons-annotations-4.0.4.Final.jar
  • aopalliance-1.0.jar
  • jackson-mapper-asl-1.9.13.jar
  • spring-tx-4.0.0.RELEASE.jar
  • slf4j-log4j12-1.7.1.jar
  • log4j-1.2.17.jar
  • commons-io-2.4.jar
  • spring-web-4.0.0.RELEASE.jar

  • spring-core-4.0.0.RELEASE.jar
  • hibernate-spatial-4.3-SNAPSHOT.jar
  • spring-aspects-4.0.0.RELEASE.jar
  • hsqldb-2.0.0.jar
  • classmate-1.0.0.jar
  • jboss-logging-3.1.3.GA.jar
  • hibernate-validator-5.0.2.Final.jar
  • spring-orm-4.0.0.RELEASE.jar
  • hibernate-ehcache-4.3.0.Final.jar
  • slf4j-api-1.7.1.jar
  • commons-collections-3.2.1.jar
  • jackson-core-asl-1.9.13.jar
  • spring-expression-4.0.0.RELEASE.jar
  • commons-logging-1.1.3.jar
  • spring-context-4.0.0.RELEASE.jar
  • ehcache-core-2.6.6.jar
  • hibernate-jpa-2.1-api-1.0.0.Final.jar
  • spring-webmvc-4.0.0.RELEASE.jar This is my web.xml file content:

                <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
        </listener>
</web-app>

This is my plugin.xml file content:

<?xml version="1.0" encoding="UTF-8"?>
<plugin id= "mitu.wcm.api.custom" 
    name= "Spring Custom Action" 
        version= "1.0.0" 
        provider-name= "IBM" >
        <extension-point id= "CoMiCustomActionFactory" name="CoMiCustomActionFactory" />
        <extension point="com.ibm.workplace.wcm.api.CustomWorkflowActionFactory" id= "CoMiCustomActionFactory" >
                <provider class= "it.wcm.api.custom.SpringCustomActionFactory"/>
        </extension>
</plugin>

When I try to deploy the EAR under my WAS 8, the EAR installation is OK but when I try to start it, I get this error:

[3/11/14 9:14:38:719 CET] 000000e7 RegistryLoade W   CWXRS0010W: Error while processing: file:/opt/IBM/WebSphere/wp_profile/installedApps/192Cell/CoMiGeoMedia.ear/CoMiGeoMediaWeb.war/WEB-INF/plugin.xml
                                 java.lang.ClassCastException: com.ibm.wkplc.extensionregistry.Extension incompatible with com.ibm.wkplc.extensionregistry.ExtensionPoint
    at com.ibm.wkplc.extensionregistry.RegistryCache.putExtensionPoint(RegistryCache.java:341)

        at com.ibm.wkplc.extensionregistry.RegistryLoader.loadPluginXml(RegistryLoader.java:482)

I add the full log to the question. Can anybody tell me where I'm wrong? Are spring and hibernate causing the listed error? Ho can I solve it?

Try the following plugin.xml file - take note of the attribute ordering and removal of whitespace for the attributes names/values:

<?xml version="1.0" encoding="UTF-8"?>
<plugin provider-name="IBM" version="1.0.0" name="Spring Custom Action" id="com.ibm.workplace.wcm.api.custom">
    <extension-point name="CoMiCustomActionFactory" id="CoMiCustomActionFactory" />
    <extension point="com.ibm.workplace.wcm.api.CustomWorkflowActionFactory" id="CoMiCustomActionFactory" >
            <provider class="it.wcm.api.custom.SpringCustomActionFactory"/>
    </extension>
</plugin>

Hope this helps. Ensure that you have the included JAR files in order to compile the code. You'll also need:

  • ilwwcm-api.jar - located in: $PORTAL_HOME$/wcm/prereq.wcm/wcm/shared/app
  • wp.base.jar - located in: $PORTAL_HOME$/base/wp.base/shared/app

You'll also need to ensure that when deploying the application, that's it's tied to the WebSphere_Portal instance AND that it's Startup Behavior (Enterprise Applications --> Deployed_WAR --> Startup Behavior), has it's start up Order set to 30 (default for WCM).
