WebServices Soap Error (InvocationTargetException)

Hello All,

I am just trying to add web services to our existing app to make an api for a couple things and have been running into some trouble.

If I try to go to the wsdl page of our app (or calculator sample app) by doing the webapp/ws/Class?wsdl to see the xml definition I get the first stack trace below. to make sure it did have something to do with i just made a test method that takes a string and returns a string and registered it with WOWebServices in App start up. This should not require a serializer as I understand.

The second problem I am having is I cannot get the WebServicesAssistant to connect to anything I get a stack trace in the app I am connecting to every time. This includes the sample apps. That trace is the second trace below.

I read a post about maybe this having something to do with the xalan.jar file not being there but this did not fix it.

Thanks in advance for any help

Brendon Allen
