You might consider to upload files with AJAX instead of multipart form. 
That gives you the option to show a progress bar and thus better user 
experience. But of course it means you have to write and maintain more 
code.

Here are samples:

What servlet container do you use? Java version? Maybe it's an
internal container's limitation?

HiDo you get an error message?
No error message is obtained during the fileupoad.
In our application all request are mapped to the filter. We traced our request 
for the case of fileupload through the jsp mentioned above.The 2 different 
scenario for different file sizes are:
- When the file size is less than 2gbIn this case our fleupload is 
successful. On checking the request in the filter, the 
ServletRequest.getContentLength() methodreturns the correct file length size in 
bytes.
- When the file size is greater than 2gb (2^32-1 bytes)In this case our 
fleupload is not successful.The fileupload action cannot proceed as per the 
logs and nothing else is thrown.On checking the request in the filter the 
ServletRequest.getContentLength() method returns 0 instead of the correct file 
length size in bytes.The further mapping for the request hence does not proceed.
It is evident that there is problem with the servlet-api, that the 
ServetRequest.getContentLength method returns a 32-bit int insteadof a 64-bit 
long.This is why it fails for file sizes in bytes larger than 2gb.
What needs to be done in order to correctly read Content-Length headers with 
numbers bigger than 2^32 - 1, so that it supports uploadsgreater than 2gb.

Thanks

 Hi, File upload in my struts application is not successful for 
greater than 2 gb. After previous discussion here on previous thread, 
I migrated my application to struts 2.3.24 as the only 
possible solution in form of jakarta-stream parser for large size 
uploads (greater than 2gb). But after successfully migrating to 
struts 2.3.24 from 2.1.8, file upload greater than 2 gb still not 
supported. I want to use jakarta- streams for this purpose.Following is the 
code snippet: In struts.xml:lt;constant 
name="struts.multipart.parser" value="jakarta-stream" 
/gt;nbsp;lt;constant name="struts.multipart.maxSize" 
value="3147483648" /gt; jsp file:lt;s:form id="uploadData" 
action="abc_UploadAction" namespace="xyz" validateFields="false" 
method="post" enctype="multipart/form-data"gt; 
Alongwith with configuring server.xml with maxPostSize e
 lement and mutipart-config in web.xml But still the file upload 
request for greater than 2 gb not successful.nbsp; Thanks

Do you get an error message?Log entries?Stack traces?
Please give us more detail about what is happening.
