Solved: Error Rendering JSP Component After Upgrade to SP1...

PORTAL Administration and Development

Hi everyone,

I have developed an application in SP9 that uses a JSPDynPage Portal Component. The application was working fine before the upgrade.

After I did my upgrade to SP12, it sometimes gives me the following error: "Error rendering jsp component". And without me doing anything, the problem after a while gets fixed by itself.

The problem has been on and off now for two days. Any ideas of why this error is happening.

Hi Alaa,

The defaultTrace.<n>.trc log under j2ee\cluster\server0 should tell what's wrong with JSP parsing/compilation.

Dmitry

Hey Dmitry,

Right now the error is not happening but I had a similar error while I was working on a testing application. Could you please tell me how can I identify the error in the log file? Here is the error log:

Hi Alaa,

This stack is printed on the component referring to the JSP, look for a one on the JSP itself, it comes before.
