Apache Axis2 throws NoSuchMethodError when trying

I am trying to hit the following web service with axis2: http://www.webservicex.net/geoipservice.asmx?WSDL

I have Axis2 locally, and I generated my classes by downloading the wsdl to my local drive and running:

./wsdl2java.sh -uri geoipservice.wsdl -p geoip -d xmlbeans -s -o geoip

This produced a build directory with a build.xml file in it, which i then ran "ant" in, and it produced a client jar in the libs folder.

I dropped this jar onto my classpath, and then I tried to hit the service using the following code:

GeoIPServiceStub stub = new GeoIPServiceStub("http://www.webservicex.net/geoipservice.asmx?WSDL");
GetGeoIPDocument req = GetGeoIPDocument.Factory.newInstance();
GetGeoIP gic = req.addNewGetGeoIP();
gic.setIPAddress("74.125.91.105");  // google.com
GetGeoIPResponseDocument resp = stub.getGeoIP(req);
System.out.println(resp.getGetGeoIPResponse().toString());

Things seem to run at first, and I see the results coming back in the syslog, but before it finishes it throws this exception:

java.lang.NoSuchMethodError: org.apache.axiom.om.impl.OMStAXWrapper.<init>(Lorg/apache/axiom/om/OMXMLParserWrapper;Lorg/apache/axiom/om/OMElement;Z)V

I've googled all over and haven't been able to find what is causing this. Can anyone help me find what I'm doing wrong? Thank you.

You get NoSuchMethodErrors if your compiler used a different class definition (during compilation) to create your .class file then the jvm has at runtime.

In your case, it misses the constructor for org.apache.axiom.om.impl.OMStAXWrapper(org.apache.axiom.om.OMXMLParserWrapper, org.apache.axiom.om.OMElement)

It probably means you have the wrong org.apache.axiom library somewhere on your classpath.
