    Lightbulb 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.

    Default Re: Java heap space problems

    Sounds less a server config problem and more of a code problem...are you keeping the entire contents of the file in memory as you 'upload'? Post the relevant code
