NullPointerException at ISecuritySession.getEffectivePreferredViewingLocale()

I got the following error when I use getReportParameters in Publication. Error occurs at . What I try to do is to set parameters for IReport contained in Publication. Any help will be greatly appreciated.

The following code works in the server box version 3.1 but not works in the other server box version 4.0 .

Exception in thread "main" java.lang.NullPointerException: while trying to invoke the method com.crystaldecisions.sdk.occa.security.internal.ISecuritySession.getEffectivePreferredViewingLocale() of an object loaded from field com.crystaldecisions.sdk.plugin.desktop.report.internal.Report.m_session of an object loaded from local variable 'this'
