Large war file uplod error

The default tomcat7 install for the module "manager" contains the maximum file 
size in 50MB or 52428800, there's the default value in \webapps\manager\WEB-
INF\web.xml

   <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>

I changed that value to a greater and it works.

Regards,

Alejo
