You are using different versions of JasperReports to compile the report design and to generate the report.

You were right.

 

But, now I am getting a blank page with the url https://...../jsp/pdf.jsp

 

Any idea why it is a blank page with no errors?

 

Thank you again!

Nevermind, it was a local PC browser problem. The problem is with IE 6.0.2 SP1 on my PC. It works fine on other PC with the same version.
