I'm trying to deploy an application to Google App Engine that will eventually interface with JIRA and other services over SOAP. The J2SE 6 java.xml.soap.* APIs are not supported by the GAE JRE. What other simple libraries are available for building requests and parsing results over a URLConnection?
Axis and CXF seem to be the generally accepted SOAP/Web Services engines, but they seem somewhat overkill for my needs. Any recommendations?
I don't think Axis/cxf are overkill for you. They are fairly simple to use, solve the problem and are a standardized solution to solve your problem.
If you can explain why you do think they are so much more than you need, I'll be glad to reconsider
Hi All,
I needed to do a SOAP web service call from Google App Engine. I deployed axis.jar to perform the call from App Engine, but no luck there since I'm getting this error:
javax.servlet.ServletContext log: Exception while dispatching incoming RPC call

I don't even directly use the SOAPException, but it looks to be used at runtime. Deploying saaj.jar did not help neither. When I explicitely use a SOAPException in my code, the compiler says:
javax.xml.soap.SOAPException is not supported by Google App Engines's Java runtime environment
Anybody succeeded in making a SOAP web service call??
Thanks, Daniel
OK, votes are open to whitelist the javax.xml.soap.* classes, but since more than one year!
It's strange though, how it has been easy to call the same SOAP web service using Google Apps Script from a Google Spreadsheet, and it is not even a possibility on GAE.
