Deployed Applications result in HTTP404 when clicking on Link in ME Client

When I click on a Link of an Application in my ME CLient (JSP) it always results in a HTTP404 instead of loading the Application. I am using Mobile Time and Travel.

Applications are deployed fine and the WebConsole of the ME says all Applications are deployed successfully.

Is there anything I have to take care for when uploading the Applications or after deployment?

Does the WAS Backend need a specific configuration for this?? I did everything like written in the manuals.

Thanks Nicolas
