Hi Pietschmann,
It is the memory problem.
I upgraded tomcat from 4.1.29 to 4.1.31 (the latest 4.1), it reports
specifically outofmemory error. So I increased JVM heap to -Xms128m
-Xmx256m, it worked. Thank you very much for the valuable help.
Now here is another minor problem. Every time when I first run the servlet
to generate a pdf file after rebooting tomcat or leaving it for a couple of
days, it gives me the following exception. Then I run it again, it works
fine. Looks like there is something missing to initialize fop in my servlet.
Could you give me a hint?
Best regards,
HTTP Status 500 -

Unfortunately, it's indeed unhelpful.
My best guess is that there is a memory problem caused by
a large embedded font (CJK fonts tend to be large). Try
to increase the JVM memory significantly. There may be any
number of other possiblities, like security violations or
a tomcat bug.
If possible, get the exception which triggered the JSP
exception handler. Have a look at the compiled JSP code.
