[SOLVED] MWG HTML UI cannot be started after upgrade to 10.2.0

a new version of webswing (a commercial version instead of an open source) is used in 10.2.0. During the upgrade a new configuration file is not replaced but stored as /etc/mwg-ui/webswing.config.rpmnew instead. The Web-UI cannot be started, a blank site is shown instead of the login mask. 

HTTP Status 500 – Internal Server Error

Type Exception Report

Message Webswing failed to start!

Description The server encountered an unexpected condition that prevented it from fulfilling the request.


javax.servlet.ServletException: Webswing failed to start!


rename/backup /etc/mwg-ui/server.xml and /etc/mwg-ui/webswing.config:

mv /etc/mwg-ui/server.xml /etc/mwg-ui/server.xml.old
mv /etc/mwg-ui/webswing.config /etc/mwg-ui/webswing.config.old

reinstall mwg-ui:

yum reinstall mwg-ui
