Hi.
As was stated - you seem to be adding some elements into a
HashMap. Is this
going into an infinite loop by any chance?
Try using "java -Xint" when starting java - this
is quite helpful in
identifying the exact location.
If its not due to an infiinte loop, then you may need to
check that you are
not trying to process a really large result set, and
creating a large number
of intermediary objects during processing.
Hope this helps,
Rgds,
Saurabh Bobde

Hi Zhisheng,
it seems that you have a page, that returns a listing of
some kind. Probably
from a database selection. There are too many results
returned, which then
cause an OutOfMemory Exception.
From the Stacktrace it seems that you are putting things
into the context
eithin a screen, until your memory is exhausted. Find the
screen, and you
found your problem.
