Null Pointer from org.apache.axis.message.MessageElement.addTextNode
Hi
I'm getting a null pointer exception on invoking a call object. This happens for any call with parameters set, though I'm certain, from having debugged the code, that it is not 'caused by passing nulls for parameter values, the exception occurs even on calls where all the values are present and correctly typed. The stack trace for the error is below

In case anyone else has this problem, I've determined it was being caused by a conflicting copies of saaj.jar, the javax.xml library.

I think the error is occuring in my client while it is constructing the message to send, TCPmon doesn't pick anything up as I don't think the client gets as far as sending anything.

Did you try verifying what is being sent on wire to the server using TCPMon?
Start TCPmon on some port and redirect the content to the tomcat host and port. Make sure you give tcpmon port in the portQName string rather than the tomcat port
Assuming I would like to start tcpmon on 9090 and have my tomcat on local machine 8080. I'd start tcpmon as
java org.apache.axis.utils.tcpmon 9090 localhost 8080

The code generating the error is as follows
ServiceFactory serviceFactory = ServiceFactory.newInstance();
webService = serviceFactory.createService(wsdlUrl, serviceQName);
...
Call opCall = webService.createCall(portQName, operationName);
...
return opCall.invoke(values);
where values is an object array of correctly typed parameter values. Does anyone have any hints as to what the root of this problem might be?

Re: Null Pointer from org.apache.axis.message.MessageElement.addTextNode
Posted by jayachandra <ja...@gmail.com>.
Did you try verifying what is being sent on wire to the server using TCPMon?
Start TCPmon on some port and redirect the content to the tomcat host and
port. Make sure you give tcpmon port in the portQName string rather than the
tomcat port
Assuming I would like to start tcpmon on 9090 and have my tomcat on local
machine 8080. I'd start tcpmon as
java org.apache.axis.utils.tcpmon 9090 localhost 8080
