Hi - I have build jbilling from source using following steps:
1. unzip jbilling.zip and jbilling-src.zip.
2. taken latest code from repository using git
3. build src - BUILD Successful
4. ant prepare-test
5. ant test-ws

I am getting following error on step #5 above.

test-ws:

I am unable to determine if it could be a data issue or a code issue. The code is latest from repo for sure. This issue might have been faced by people starting to use jbilling. let me know if someone can make something out from this. I was thinking that at least the ant-test would work out of the box.

Thanks
