Wildfly 10.1 - JAXB Classloader

[fuinhaazul]

Hi there.

Im going crazy with wildfly 10.1 classloader. Maybe somebody has any hints?

I want to put all jaxb generated classes on modules as well some utility classes that uses these classes.

I was succeded on the task until i created C.JAR, a utility jar that uses B.JAR JAXB classes.

My structure today is:

EAR (DEPENDENCIES: COM.MODULE1 EXPORT)

      WAR

          TestClass1.java (for testing - see below)

COM.MODULE1:

<?xml version="1.0" encoding="UTF-8"?>
<module xmlns="urn:jboss:module:1.3" name="com.module1">
  <resources>
  ...
  
  <resource-root path="A.jar" />
  <resource-root path="B.jar" />
  <resource-root path="C.jar" />
  </resources>


  <dependencies>
  <module name="com.jaspersoft" export="true"/>
  <module name="com.jbpm" export="true"/>
  <module name="org.apache.log4j" export="true"/>
  <module name="com.google.guava" export="true" />
  <module name="com.sun.xml.bind" export="true" />
  <module name="org.slf4j" export="true" />
  <module name="javax.api" export="true" />
  <module name="javax.xml.bind.api" export="true" />
  <module name="org.postgresql" export="true" />
  <module name="oracle.jdbc" export="true" />
  <module name="javax.faces.api" export="true" />
  <module name="org.apache.commons.io" export="true" />
  <module name="org.apache.commons.logging" />
  <module name="org.apache.commons.collections" export="true"/>
  <module name="org.apache.commons.lang" export="true" />
  <module name="org.apache.commons.beanutils" export="true" />
  </dependencies>
</module>

TestClass1.java

  // ------ STEP 1
  //This class is inside C.JAR
  //and parses a XML using JAXBContext.newInstance(PACKAGE NAME)
  //where the classes specified on PACKAGE NAME is inside B.JAR
  DIOrganizer diOrg = new DIOrganizer(diEl);
  diOrg.organize(XML_STRING);


  // ------- STEP 2
  //PARSES DIRECTLY using classes from A.JAR
  JAXBContext ctx = JAXBContext.newInstance(ANOTHER PACKAGE NAME);
  Marshaller marshaller = ctx.createMarshaller();

The error I get is on step 1:

Caused by: javax.xml.bind.JAXBException: Provider com.sun.xml.internal.bind.v2.ContextFactory not found
 - with linked exception:
[java.lang.ClassNotFoundException: com.sun.xml.internal.bind.v2.ContextFactory from [Module "deployment.XCape.ear.XCapeWeb.war:main" from Service Module Loader]]
  at javax.xml.bind.ContextFinder.newInstance(ContextFinder.java:146)

If I add on the manifest:  com.sun.xml.bind services export, then the error occurs on step 2 (pass the step 1), and the exception is:

java.lang.ClassCastException: com.sun.xml.bind.v2.runtime.JAXBContextImpl cannot be cast to javax.xml.bind.JAXBContext: javax.faces.FacesException: #{backing.actionSaveDiagram}: java.lang.ClassCastException: com.sun.xml.bind.v2.runtime.JAXBContextImpl cannot be cast to javax.xml.bind.JAXBContext
  at com.sun.faces.application.ActionListenerImpl.processAction(ActionListenerImpl.java:118)
  at javax.faces.component.UICommand.broadcast(UICommand.java:315)

Any help? the idea is to avoid sendind large .ear files with classes that will never change again (JAXB Classes)

Thanks

Forget it. A crappy library was the cause of the problem because it has the jaxb implementation inside it.

Thanks anyway
