Question

I have been running a simple Junit testclass with a single test method.
I am stuck with the below error.
The stackTrace is as follows

Answer 1

I did not have to add any jar files to the CLASSPATH though. I solved it by adding the following system property:
-Dorg.apache.commons.logging.LogFactory=org.apache.commons.logging.impl.SLF4JLogFactory
is this mandatory in running the webservices through JUNit?
