Thread: Java heap space problems

hi all

Actually i want to upload more than 500 mb file using struts file upload features.
I have successfully upload the file less than 200 mb.

I have increase the java heap size and tomcat heap size in catalina.bat file and in myeclipse also.
i have also set java_opts and catalina_opts in environment variable.
i have also set in controller class in struts-config.xml file as
<controller maxFileSize="1G" nocache="true" bufferSize="1073741824"/>

i changed the server.xml file and web.xml file as you suggested.


In conf\server.xml

<Connector port="80" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443"
maxPostSize="67589953" />
In webapps\manager\WEB-INF\web.xml

<multipart-config>
<!-- 52MB max -->
<max-file-size>52428800</max-file-size>
<max-request-size>52428800</max-request-size>
<file-size-threshold>0</file-size-threshold>
</multipart-config>


but still i get this problem while uploading more than 250 mb files.
