OMException: No meta factory found for feature 'dom';

Question

I am working on a SOAP client (Dynamic Dispatch Client) and I am running into an error when trying to execute the call after the JAR is created. I am using a shaded JAR to include all dependencies within the JAR. The odd thing is that the client works from my test class in Eclipse, however, when I deploy it to the server and try to invoke the call, I get the following error:

• org.apache.axiom.om.OMException: No meta factory found for feature 'dom'; this usually means that axiom-dom.jar is not in the classpath or that the META-INF/axiom.xml resource can't be read

This seems to happen when I invoke the call to create the message SOAPMessage request = mf.createMessage();. I took a peek inside the JAR and do see an "axiom.xml" file within the "META-INF" directory in my JAR and the following three jars are present in my Maven Dependencies in my project build path:

1. axiom-dom-1.2.21.jar
2. axiom-api-1.2.21.jar
3. axiom-impl-1.2.21.jar

Here is the complete code for my class that is making the call to the SOAP service:

Has anyone else run into this issue? I can not figure it out for the life of me. I will admit I am not extremely familiar with interacting with SOAP services. Any pointers or suggestions on how to resolve this is greatly appreciated.

Thanks in advance!
