Thread: Java heap space

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"/>
but still i am facing same problem like this.

pls suggest me how to upload file more than 500 mb.

Hello.
There is one config file somewhere in tomcat folder.
Did you go and change the size there? You already said you did. But still I wanted to make sure if you did the right way.

You have to modify two possible limits:

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>
