I'm trying to use JAXB in jBPM, which produces the error mentioned in https://jira.jboss.org/jira/browse/JBPM-1404. I have downloaded the source code and tried to apply the patch described in the jira by replacing only the class and the inner classes. Unfortunately I am not able to get it to work. I am using the jBPM bundled with JBoss ESB 4.4, and I have downloaded and patched jpdl-3.2.2-SOA-4.2 from subversion. The findClass in ProcessClassLoader now looks like: public Class findClass(String name) throws ClassNotFoundException { | Class clazz = null; | | FileDefinition fileDefinition = processDefinition.getFileDefinition(); | if (fileDefinition!=null) { | String fileName = "classes/" + name.replace( '.', '/' ) + ".class"; | byte[] classBytes; | try { | classBytes = fileDefinition.getBytes(fileName); | clazz = defineClass(name, classBytes, 0, classBytes.length); | } catch (JbpmException e) { | clazz = null; | } | // Add the package information | final int packageIndex = name.lastIndexOf('.') ; | if (packageIndex != -1) { | final String packageName = name.substring(0, packageIndex) ; | final Package classPackage = getPackage(packageName) ; | if (classPackage == null) { | definePackage(packageName, null, null, null, null, null, null, null) ; | } | System.out.println("package is: "+packageName); | } | } | | if (clazz==null) { | throw new ClassNotFoundException("class '"+name+"' could not be found by the process classloader"); | } | | return clazz; | } | - and the output is: 20:14:04,030 INFO [STDOUT] package is: dk.lenio.em.smile.jbpm.vo 20:14:04,063 ERROR [GraphElement] action threw exception: "dk.lenio.em.smile.jbpm.vo" doesnt contain ObjectFactory.class or jaxb.index javax.xml.bind.JAXBException: "dk.lenio.em.smile.jbpm.vo" doesnt contain ObjectFactory.class or jaxb.index I have a class named ObjectFactory in the package dk.lenio.em.smile.jbpm.vo.
