FileUploadBase UnknownSizeException when uploading a huge file

Question

I am trying to upload a huge file size[more than 5 gb] using struts1.2form file and apache.commons.fileupload 1.0. I saw that maximum limit for file upload in struts1 is 256M. Is there any way to change this? I am getting the below exception.

By default file size limit is 250MB. I have increased to 350MB. It works fine. After that i have increased it to 10G and got the below exception. Is it possible to upload a huge file using struts1.2? is there any other way to upload huge file?

configure the maximum limit in struts controller controller processorClass="your class" nocache="true" locale="true" contentType="text/html;charset=UTF-8" **maxFileSize="15G"/**

When you are using apache.commons.fileuploa-1.1 there is a constraint that FileUpload refuses parsing requests of unknown length. In the succeeding version stream has been introduced to overcome the size issue. Below issues were reported in apache.commons.fileupload in 1.2 & 1.3 1. After uploading, temp file is not removed 2. Input stream is not closed which leads to memleak.

REF: refuses parsing request of unknown lenght Memleak when stream is not closed. Memleak

Hope it helps....
