NullPointerException in viewer.processHttpRequest(..)- Crystal Reports 9 to BO BI3.X and above

28 Views

Hi,

I have just started working on migrating from Crystal Reports 9 to SAP BO BI 3.x.

Currently the sample I am working on connects to the repository which contains the Crys Rep 9 version reports.

After migration of a sample report from 9 to BI 3.x, I get a Nulpointer Exception at viewer.processRequest(..)

Note: I havent used the latest jars yet.

Below is the sample code

CrystalReportInteractiveViewer viewer = new CrystalReportInteractiveViewer();

IReportSourceFactory factoryPS = (IReportSourceFactory) enterpriseSession.getService("PSReportFactory");

Object reportSource = factoryPS.openReportSource(ReportID,Locale.ENGLISH);

viewer.setReportSource(reportSource);

...(setting report parameters)

...(setting viewer properrties)

....

viewer.processHttpRequest(request, response, this.getServlet().getServletConfig().getServletContext(), null);

I tried debugging to find out the source of this exception, but in vain.

I am able to get the report ID..the report Object..but on the mentioned line this exceptions comes up.



Can anyone help me in this?



Also in the folder C:\Program Files\Business Objects\Common\4.0\java\lib, there are 70+ jars.Do i need to use all of them?

Are there anymore jars I should look for apart from the above path?



Thanks,

Raaj
