Got NoClassDefFoundError when invoking Axis2 webservice deployed with maven in weblogic - maven

Question

I'm trying to deploy axis2 webservices in weblogic server using maven. The project has maven modules and one of that is a war that i have defined the axis servlet in. The wsdl was there, so i used wsdl2code plugin to generate the xmlbean and schema and put that in a jar module. Structure is as below.
--lv-ear (ear with dependency on war)
|
--lv-ws
|
--lv-ws-ccid (jar module with skeleton and xmlbeans)
|
--lv-ws-ecs (jar module with skeleton and xmlbeans)
|
--lv-ws-web (war module with dep on jar modules)
|
--WEB-INF
|
--conf/axis2.xml
--services/ccid/services.xml
I built and deployed the ear to weblogic domain. The war was deployed successfully as part of ear and services were deployed. I am able to access wsdl files. When I tried to call the service, i got the below ClassNotFoundException for a schema file.
Caused by: java.lang.ClassNotFoundException: schemaorg_apache_xmlbeans.system.s2104B1E6E09A2A85656B3E630BA151C1.TypeSystemHolder
I saw that the random string in that path differed fo me. So I tried to call again and got below NoClassDefFoundError, which persists even after I tried with different approaches.
java.lang.NoClassDefFoundError: Could not initialize class com.lv.ws.ccid.xmlbean.InputDocument

I searched for this and found something that told to configure app server for axis2 based on http://axis.apache.org/axis2/java/core/docs/app_server.html . When I tried it I got below error.
weblogic.xml.stax.XmlStreamInputFactory can not be cast to javax.xml.stream.XmlInputFactory
After discarding that configuration, I did some other possible deployments by having the webservice skeleton and xmlbean files in an aar and put the aar inside WEB-INF/services. I also tried putting Class-Path entry in MANIFEST.MF in ear / war for the jar files, to no avail. Still I got the same NoClassDefFoundError. Can you please give me suggestions on fixing that?

Fixed it now. This was due to my lack of experience with Axis. Issue was that, I had the generated schema and xmlbean files moved to src folder and then just tried to use normal jar function and dependency to deploy.
Now, I removed them from src folder and use wsdl2code and axis2-aar plugins to generate the xmlbean and schema files dynamically and then package them in aar. Then I deployed the aar to webapp and it worked fine. I have listed the plugin configuration inside <build> below.
