Using clearquest java api with WebSphere Application Server 8.5.5
Hi, I'm developing a web application that access a clearquest database via the Java API. It works fine under Tomcat. Now I have to convert that application to WebSphere Application Server 8.5.5. At the first call to Clearquest the application and the JVM terminates:

How do I have to define the Clearquest API library in WAS and how to ensure access to the Clearquest DLLs used by the Java API?
Perhaps this is not the appropriate forum for this question. Which one would be better?
Thanks!

Jan 22 '15, 9:17 p.m.IIRC, you need to add the .jar files such as cqjni.jar to your class path, which I assume that you have already done that as the stack trace shows a cqjni function; and the CM API should find the native CQ libraries via the PATH system variable. If you run both WAS and Tomcat on the same machine, I can't imagine how it will not work. Is it possible that the Windows user running the WAS service cannot read the ClearQuest registry?
FYI, you can find the ClearQuest forum at
