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?
Thanks! Berthold
In the meantime I found out that ClearQuest does not support Java 64bit. It always requires a 32bit Java! Therefore we moved the ClearQuest access functions into a standalone Java application connected to the WAS application by RMI.
