I get the error below when I try to launch a mobile project. The project works if I launch it as a regular project.

Ignition 7.5.3  
Java 1.7.0\_09

Do you have Java 7? Our mobile module is only compatible with Java 6. Furthermore, you have to specify the right path to Java 6 in the mobile settings in the gateway configuration page. Make sure that your path is correct.

Java 7 would be the problem.

Given that you can specify the path, can the gateway run on 7 with the mobile module running on 6?

When will it support 7?

That's worth a shot...

Never ☹

Whatever Mobile.Next is will run on Java 7, but the current incarnation won't ever be compatible.

Yes it can! 😃
