How big a war file should be?

Question

Tomcat 7 manager limit the war file size to 50 Mo.

• Why this limitation of 50 Mo ?
• What should be the maximum war file size ? (in practice)

I'm working with Grails 2.2 which generate a minimal WAR of 28 Mo. So, the limit of 50 Min is very easy to reach.

Answer 1

This is only a limit set for you to upload and deploy via the Tomcat 7 manager. There really is not a limit on the size of the war file you can deploy to a tomcat server.

Here is a link that can help you increase this upload size.

Quoted from link --

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 max –>

 <max-file-size>52428800</max-file-size>

 <max-request-size>52428800</max-request-size>

 <file-size-threshold>0</file-size-threshold>

 </multipart-config>

Answer 2

If you're using Tomcat 8, the max-file-size is not in web.xml anymore. Instead, open conf/server.xml and find the tag entry for the HTTP connector. Then add the

maxPostSize="0"

attribute and value to this tag. When you have completed editing the conf/server.xml file, save it and restart Apache Tomcat.
