code doesn't work when called from insite silk performer

We are facing issues while logon to QuickFix engine through SilkPerformer. The Silk script calls the java method which creates the session and tries to logon. When we execute this from command prompt it runs fine but when we try to run it from Silk Performer the program cannot logon. It was not throwing
any exceptions but sometime i saw that an hs_pid_err.log is created. Here are the contents. Any help will be appreciated.
