IFrame Web-Application for use with Liferay

In Liferay its possible to implement several portals in one installation/deployment using (open) communities. Unfortunatly the URLs of these (open) communities are something like

http://www.<Host>.com/<context of liferay deployment>/web/140012/start

To "hide" these URL you can use a iFrame-Web-Application which is running under a more suitable context (like: "/jobs").

Download an EAR-File of an example application here.

The EAR-File contains an index.jsp. In this file you have to edit the source-declaration in the iframe-tag (src).
