I got error while trying to return 3D Object array from a service method.
Here is the stack trace:

Could someone tell me what is going wrong? I am using Tomcat 5.0 and Axis2
1.4. Following is my client side call:
EndpointReference targetEPR = new EndpointReference(wsServerUrl +
"services/abcd_listFunctions");
OMFactory fac = OMAbstractFactory.getOMFactory();
OMNamespace ns = fac.createOMNamespace("abcd__listFunctions", "ns1");
OMElement payload = fac.createOMElement("listFunctions", ns);
// Creating the node username
OMElement authenticationToken = fac.createOMElement("authToken", ns);
authenticationToken.setText(authToken);
// Adds the nodes to SOAP body
payload.addChild(authenticationToken);
Iterator children = null;
// Ceating options
try {
Options options = new Options();
ServiceClient client = new ServiceClient();
options.setTo(targetEPR);
options.setAction("listFunctions");
client.setOptions(options);
client.setTargetEPR(targetEPR);
//Blocking invocation
OMElement result = client.sendReceive(payload);
} catch (AxisFault axisFault) {
axisFault.printStackTrace();
}
