You are writing to and replacing a text file, for every single request
to your JSP?

I see a red flag in your above statement: "show some dynamic JSP by
running java method at background". Could you please clarify this and/or
post some code? If you are starting a new thread to perform some tasks
in the background and not waiting for it, you can cause all sorts of
problems.
Then, we try to trace the code, we found that when it return blank page
1. server have receive the GET request and have return a packet to client
which the packet body is "0"
Is that a byte 0x00 or a "0" character? some more details would
definitely help.
2. However, if the page have a counter on it. we found the counter
haven't
updated. So, it seems that whole jsp page haven't run yet.
If the original page isn't returned properly, the counter (often an
image) is never referenced, and therefore not updated.
