Not able to create a java class included in custom jar from script

Hi,

We need to call a third-party web service from within SAP Sourcing and so we have created and deployed a custom JAR. However I am not able to create any of the custom classes included in this object. I have created a simple JAR file having just a "Hello World" message and got our BASIS team to deploy this (they deployed using the steps mentioned in Installation Guide Section 4.2.4 - we are using Sourcing Wave 9). I have added the required import statement in my test script and included this line:

HelloWorld test = new HelloWorld();

When this script executes, it gives the error:

Class:HelloWorld not found in namespace.

Can you please give your suggestions on how to fix this error?

Thanks,

Gayathri
