Migrating Application from Tomcat V 8.5 to Websphere Application Server

When I am trying to deploy my war file from tomcat to websphere I am getting the following error. 1)org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [org.apache.cxf.bus.spring.SpringBus]: Constructor threw exception; nested exception is org.apache.cxf.bus.extension.ExtensionException: Could not load extension class org.apache.cxf.ws.policy.AssertionBuilderRegistryImpl. 2)org.apache.cxf.bus.extension.ExtensionException: Could not load extension class org.apache.cxf.ws.policy.AssertionBuilderRegistryImpl. 3)java.lang.IncompatibleClassChangeError: org.apache.neethi.AssertionBuilderFactory

I tried by changing the class loader from parent first to parent last(Vice-Versa).But still I am getting same error

Help me out.

There are potentially several issues with your app:

  1. You probably include Java EE jars in your application - like jee.jar, servlet.jar etc - please remove all these jars from WEB-INF/lib directory.
  2. It looks like you are bundling your own web services engine (CXF) inside your application. tWAS provides its own web services engine. So you either need to migrate to the provided or disable tWAS one. Check the Using a third-party JAX-WS web services engine page. You will need to set DisableIBMJAXWSEngine property and configure module classloader for your war to parent last.

I still would recommend migrating to Liberty if possible, instead of traditional.
