title: Apache axis2/axiom NoSuchMethodError
body: <p>Using RAD v7 with WebSphere AS v6.1, I am receiving the following; </p>
  
  <blockquote>
    <p>java.lang.NoSuchMethodError: org/apache/axiom/om/OMAbstractFactory.getMetaFactory()Lorg/apache/axiom/om/OMMetaFactory;</p>

  <p>Other answers (<a href="https://stackoverflow.com/questions/6802883/apache-axis2-throws-nosuchmethoderror-when-trying-to-hit-web-service">here</a> and <a href="https://issues.apache.org/jira/browse/RAMPART-372" rel="nofollow noreferrer">here</a>) have indicated that this is due to conflicting jars. I have installed the latest RAD/WS fixpack, made sure I'm using only one version of axis2 (v1.6.2) &amp; axiom-api (v1.2.13), cleaned &amp; built my workspace multiple times and made sure the correct jars are being deployed. I have also tried setting the WAS class loader policy to "parent last".</p>
  
  <p>My question: Is there any reason other than conflicting jar versions that would cause this problem?</p>
