License question - using WL client files

Hi,

We have a developer who is using wl files in an application running on UNIX, which connects to a WSDL and performs some operations.  He copied the same files, on same host, to another application (which is a duplicate of the previous application), and is now getting a "license not found" error.

I noticed the difference was that in the new app, a jar was added to META-INF which included the wlfullclient.jar.  So I figured this was the problem.  But then the developer said he tested without the new jar, and still had the error.  I did checksum on all the *wl* and *bea* files in the application, and they are the same.
