Hi.. Previously I thought it was session timeout, therefore I set a higher session timeout value.
I tried to generate the pdf file again, this time it still timeout but it haven't reach the threshold yet. So, I can confirm it's request timeout. I tried to use a dummy ajax which keeps refreshing one part of the page. It seems to be working. The page now will not have timeout problem.

You original message implied the former, since you were trying to correct it with session.setMaxInactiveInterval(), but if it's a request timeout that's not going to have any effect. It sounds like the PDF generation is taking too long, causing the browser to timeout the request because it gives up on getting a response. In that case, the way to fix it is to return a 'generating PDF...' response immediately and do the generation in the background. See the execAndWait interceptor for one way to approach that: http://struts.apache.org/2.0.11.1/index.html L. Simon Sew wrote: > The request timeout occurs when it is still generating the pdf.
