Null pointer exception in com.crystaldecisions.sdk.occa.report.application.ControllerBase.checkViewReportRight

Question

I am testing BOE 4.0 with a simple jsp based on the samples.  The code is what I used to test BOE xi 3.1.  But I ran into some report display inconsistencies with 3.1 so I am trying 4.0.  The code below works in 3.1  But in 4.0, I get the report viewer screen coming up but get a null pointer exception coming to the screen.

Answer 1

Hi Jason,
Call any one of the methods
viewer.dispose(); or clientDoc.close();
Do not use both in BI 4.x version.
Test the same and let me know if it works.
Thanks,
