-------------------------------------
Sorry .. small correction..
those are not hidden fields..
My form bean is containing huge data to process, in the form of array list.
This is as per my requirement. I have certain number of items in my screen
which are dynamic, number may vary from 3 items to 150 or more items.
For each item, user has to enter price, discount & various taxes details.
So, if number of items in my form are more - i have more data to submit.
in this case, while submitting the form having enctype="multipart/form-data" in
my <html:form/> tag, i am experiencing OutOfMemory error (HTTP Status 500-). I
am using commons-fileupload.jar 1.0 implementation version as i need to provide
an option to upload attachment in this page.
Where as, if i remove this upload option & enctype property form my
<html:form/> tag, i do not see any problem in submitting even more than 150
items.
What could be the reason?

> 1: I am getting java.lang.OutOfMemoryError when the form in my jsp code is as

> <html:form action="/actnMpng" enctype="multipart/form-data" method ="post" >
> - JSP code ? containing very huge data (hidden parameters) with file upload
