Hi all,
I have just upgraded the Resin from 2.1.1 to 3.1.1. It seems work well, but I
feel so confused that in the log file, it always have error messages like that:
java.lang.NullPointerException

Where _jsp._job_0list__jsp._jspService(_job_0list__jsp.java:1200) is a

I already disable the resin cache to try to solve this problem, however it
does not work.
Can anyone give me some ideas to solve this problem? Thanks.

Frank
