OutOfMemory exception on Tomcat 7

Question

When I try to deploy a war which is more than 50mb, Tomcat encounters OutOfMemory exception. I've tried to add CATALINA_OPTS and increased heap size but yet not working. Opts used - Xms=512M - Xmx=1024M This is on Eclipse, however I've tried with Intellij with Tomcat configuration, with same JVM Opts, still gives me OutOfMemory exception.

Answer 1

• Go to the web.xml of the manager application (for instance it could be under /tomcat7/webapps/manager/WEB-INF/web.xml.

• Increase the max-file-size and max-request-size: 50mb

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