Have set up a server and have been demoing various aspects of Ignition to the team. One of the features I have touted is portability across platforms/mobile devices etc. We have pretty strict firewall rules set up. As of this moment I have 8088, 8043, 45900 set up to pass through to the Ignition server. When I try to open a project on my Motorola Droid4, I get java.io.EOF Exception on the phone display. I’m automatically suspecting I am missing a port on the firewall, but could be totally off track. I did update the callback interface to the correct value. Any help would be appreciated. Thanks, Ike ---

That error is not due to a firewall issue. What OS do you have? ---

For right now, the test machine we pulled off the shelf is a Windows XP x64 machine. Not sure what the boss will want to run a production version on. Thanks, Ike ---

What version of Ignition and Java are you currently using? ---

Unfortunately, the mobile module doesn’t work with Java 7 currently. 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: ```auto C:\Program Files\Java\jre6\jre\bin ``` ---

Removed Java 7 from that machine. It is only an in-house test/evaluation machine at this point anyhow. Changed a line in the config to point everything to version 6, reinstalled 6 just to be sure the system knew where it was, found a couple of problems in the environment settings on the machine and corrected them to reflect 6 JRE. Server is up and running just fine except for mobile clients still. The error message I know get is “java.io.IOException: Cannot run program “C:\Program Files\Java\jre6\bin” (in directory “data\mobile\_wdir”): CreateProcess error=5, Access is denied Caused by: java.io.IOException: CreateProcess error=5, Access is denied” That path is correct for where the JRE is installed. Sorry to be a pain and appreciate the help. Have a demo in the morning, but if I can’t get the mobile version working, will just try to focus the teams attention on the regular client. Thanks, Ike ---

Oops, sorry, I didn’t put the full path there…the Java Path setting in the mobile settings needs the full path, not just the folder. So it would be: ```auto C:\Program Files\Java\jre6\bin\java.exe ``` ---

That got it. Thank you. The demo this morning went well regardless. I just showed them mobile operation on your site demo to show how it works.
