Java.Lang.OutOfMemoryError while posting huge data with
enctype="multipart/form-data"
--------------------------------------------------------------------------------------
Key: STR-3187
URL: https://issues.apache.org/struts/browse/STR-3187
Project: Struts 1
Issue Type: Bug
Environment: Tomcat 5.0, JDK 1.4.2_09, SQLServer 2000, Struts 1.1,
Spring 1.2.4, Commons-fileupload.jar 1.0
Reporter: Samba siva Rao
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.
I have more than 1000 hidden fields in this jsp.
When i check the used memory in my action class, i came to know that nearly 200
MB memory is utilizing on each action submit from this jsp (i have more actions
/ buttons in this form in different tabs).
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.
(by removing <html:file/> tags)
3: I am facing this problem only when my form is containing more hidden
parameters to post.
Where as when my form is containg less fields (which are dynamic), then i am
not facing this problem eventhough my form is with enctype="multipart/form-data"
Please find the below log generated in Tomcat.
2009-06-02 16:51:42 StandardWrapperValve[action]: Servlet.service() for servlet
action threw exception
java.lang.OutOfMemoryError
