Java Heap size error when uplaoding big XML file

[sangeetasharma <ss...@bmjgroup.com>]

Hi,

I am currently trying to unzip a zip file containing a very large XML
file(400MB) and then uploading into XML DB. This is causing me java heap
size error, however it works fine for smaller files but as soon it starts
uploading the big XML file my pc hang then java heap size problem arrives.
My camel config is something like

 <camel:route id="StartFtpInteractionTriggerRoute" autoStartup="true">
          <camel:from
uri="quartz://scheduledInteractPoll?cron=0+10+14+20+*+?" />
          <camel:setHeader headerName="routeToStart">
                  <constant>FtpInteractionPollingRoute</constant>
          </camel:setHeader>
          <camel:bean ref="routeController" method="start" />    
          <camel:stop />
      </camel:route>   
      
      <camel:route id="FtpInteractionPollingRoute"
errorHandlerRef="deadLetterErrorHandler" autoStartup="false">
              <camel:from
uri="ftp://{{ftp.interaction.url}}?username={{ftp.username}}&amp;password={{ftp.password}}&amp;binary=true&amp;localWorkDirectory={{localwork.dirpath}}&amp;filter=#interactFileFilter&amp;disconnect=true"
/>
              <camel:onCompletion>
                      <camel:filter>
                              <camel:simple>${property.CamelBatchComplete}

                              <camel:setHeader headerName="routeToStop">

                              </camel:setHeader>
                              <camel:to uri="seda:StopRouteRoute" />
                      </camel:filter>
              </camel:onCompletion>
               <camel:log message="Downloading the ${file:onlyname} from

            </camel:setHeader>

            <camel:when>
              <camel:simple>${file:ext} == 'xml' and ${file:onlyname} !=
