That’s correct, the mobile module currently is not compatible with Java 7. You will need to have Java 6 installed (you can have Java 6 installed concurrently with Java 7), and on the Mobile Settings page on the gateway, you will have to put the path to the Java 6 version of the java.exe file, which is usually something like: C:\Program Files\Java\jre6\jre\bin\java.exe As for the project list, the default behavior is to list all projects. There currently isn’t a way to filter which projects to show. You can have a user directly open a client with this URL: ```auto http://xx.xx.xx.xx:8088/main/system/mobile?project=MyProject ``` ---

The mobile module does not currently work with Java 7. You need to install Java 6 in order for it to work.
