Application hangs in Fedora 9

[tristanlee85]

My laptop with XP died, so I am trying to get TS to work using my serial port on Fedora 9. First off, it looks like I have to run the application as root or I don't have permission to use the serial port. Here is the output:

Code: Select all

Jar Name:TunerStudioMS.jar
Experimental:  JNI_OnLoad called.

So, I run it as root and I get this:

Code: Select all

[root@localhost TunerStudioMS_v0.988.5]# ./TunerStudio.sh 
Jar Name:TunerStudioMS.jar
Experimental:  JNI_OnLoad called.

That's all that happens. The splash screen displays and that is it. I need to forcefully kill Java to get it to go away.

As for my Java info:

Code: Select all

[root@localhost TunerStudioMS_v0.988.5]# java -version
java version "1.6.0"
OpenJDK  Runtime Environment (build 1.6.0-b09)
OpenJDK Server VM (build 1.6.0-b09, mixed mode)

I see 2 things....

Switch your JRE to Sun Java. I have run using OpenJava on Fedora, but I think there are a few quirks still.

On the 1st problem... Lock files.
For Fedora you need to add your user to the lock group. Debian Linux's such as Ubuntu use the uucp group for lock file permissions, but I think for Fedora it is lock. Maybe add to both to be sure

Cool, thanks. I'll give it a shot.

Well, I added myself to the 'lock' and 'uucp' groups and I no longer get the errors. Also, I downloaded the newest JDK and pointed my paths to it rather than to the OpenJDK stuff. However, I did this on the new Fedora 11. So, the application started up fine with OpenJDK (not hanging like in Fedora 9), but I noticed I only had 3 look and feel options. Once java was switched to JDK6u4, I have 4 look and feel options.

Once I purchase a USB adapter, hopefully I can get it all to work right.

Thanks, Phil!
