KB Parallels: I get "WebApp: Error 500. Communication interrupted" error when try to access Tomcat application via 80 port, however it works fine if opened directly from Tomcat via 9080 port.

Resolution

Such problem may occur if the application throws exceptions which are not caught by application itself. Or the application produces some messages, but there is no logger configured.

As solution you can switch on logging in the $CATALINA_HOME/conf/server.xml for the virtual host where the webapp is deployed as described in the article 1578.

In this case exceptions/messages will be written to disk instead of being transfered to apache and causing the error.
