Description

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

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

</html:form>

This is throwing OutOfMemoryError eventhough I am not attaching/uploading any files.

2:*** The same data is getting posted successfully if the form is submitted with out
enctype="multipart/form-data" and without providing the attachment facility.

3: Also if the data (number of items which are dynamic) is less, the form is not throwing Out of memory exception even though we are submitting with enctype="multipart/form-data" with file upload attachment fecility.

Please find the below log generated in Tomcat.
