The error is gone but seems o be givin me some other error now. I think i did not mak my self clear in my question what i have done. Step 1 : I have taken the Jboss 4.2.4 GA server and set my JBOSS_HOME in the environment variable Step 2 : Then install the jbpm-2.3.5 sp1.jar which has created aa jbpm folder in the deploy folder of my JBoss server. Step 3 : Then i set my JBPM_Home as the one which is created while installing the jar file in step2. Step 4: In my eclipse i have set my runtime as the jbpm_home. Step 5: I create a new JBPM process project and try to deploy the archive. It gives me an error "an unexpected error occured" and on the Jboss console its giving me follwing exception. java.lang.IncompatibleClassChangeError: class org.jbpm.job.ExecuteActionJob has interface org.jbpm.job.Job as super class         at java.lang.ClassLoader.defineClass1(Native Method)         at java.lang.ClassLoader.defineClass(ClassLoader.java:620)         at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:124)         at java.net.URLClassLoader.defineClass(URLClassLoader.java:260)         at java.net.URLClassLoader.access$000(URLClassLoader.java:56)         at java.net.URLClassLoader$1.run(URLClassLoader.java:195)         at java.security.AccessController.doPrivileged(Native Method)         at java.net.URLClassLoader.findClass(URLClassLoader.java:188)         at org.jboss.mx.loading.RepositoryClassLoader.findClassLocally(RepositoryClassLoader.java:690)         at org.jboss.mx.loading.RepositoryClassLoader.findClass(RepositoryClassLoader.java:670)         at java.lang.ClassLoader.loadClass(ClassLoader.java:306)         at org.jboss.mx.loading.RepositoryClassLoader.loadClassLocally(RepositoryClassLoader.java:200)         at org.jboss.mx.loading.ClassLoadingTask$ThreadTask.run(ClassLoadingTask.java:131)         at org.jboss.mx.loading.LoadMgr3.nextTask(LoadMgr3.java:399)         at org.jboss.mx.loading.RepositoryClassLoader.loadClassImpl(RepositoryClassLoader.java:527)         at org.jboss.mx.loading.RepositoryClassLoader.loadClass(RepositoryClassLoader.java:415)         at java.lang.ClassLoader.loadClass(ClassLoader.java:251)         at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319)         at java.lang.Class.getDeclaredMethods0(Native Method)         at java.lang.Class.privateGetDeclaredMethods(Class.java:2427)         at java.lang.Class.getDeclaredMethods(Class.java:1791)         at org.hibernate.property.BasicPropertyAccessor.getterMethod(BasicPropertyAccessor.java:317)         at org.hibernate.property.BasicPropertyAccessor.getGetterOrNull(BasicPropertyAccessor.java:297)         at org.hibernate.property.BasicPropertyAccessor.getGetterOrNull(BasicPropertyAccessor.java:304)         at org.hibernate.property.BasicPropertyAccessor.createGetter(BasicPropertyAccessor.java:280)         at org.hibernate.property.BasicPropertyAccessor.getGetter(BasicPropertyAccessor.java:275)         at org.hibernate.util.ReflectHelper.getter(ReflectHelper.java:80)         at org.hibernate.util.ReflectHelper.reflectedPropertyClass(ReflectHelper.java:71)         at org.hibernate.mapping.SimpleValue.setTypeUsingReflection(SimpleValue.java:276)         at org.hibernate.cfg.HbmBinder.bindSimpleId(HbmBinder.java:401)         at org.hibernate.cfg.HbmBinder.bindRootPersistentClassCommonValues(HbmBinder.java:334)         at org.hibernate.cfg.HbmBinder.bindRootClass(HbmBinder.java:273)         at org.hibernate.cfg.HbmBinder.bindRoot(HbmBinder.java:144)         at org.hibernate.cfg.Configuration.add(Configuration.java:669)         at org.hibernate.cfg.Configuration.addInputStream(Configuration.java:504)         at org.hibernate.cfg.Configuration.addResource(Configuration.java:566)         at org.hibernate.cfg.Configuration.parseMappingElement(Configuration.java:1587)         at org.hibernate.cfg.Configuration.parseSessionFactory(Configuration.java:1555)         at org.hibernate.cfg.Configuration.doConfigure(Configuration.java:1534) Please let e know if i am doing the integration of JBPM and Jboss correctly.
