I am trying to profile an application which I have coded in VAJ. The profiler is jprobe .However I keep on getting this exception Cannot instantiate class: com.ibm.ejs.ns.jndi.CNInitialContextFactory.. This happens when it goes to do a databse lookup. I have put the following directory in the classpath "C:\Program Files\IBM\VisualAge for Java\ide\project_resources\IBM WebSphere Test Environment" But nothing has changed..........Can somebody advise me what the problem is... Again the application is being run through Websphere test Environment in Visual age for java.
