I am a new user to Fedora 23 and linux in general. My issue is that the Defense Travel System uses Java and does not support OpenJDK. I have downloaded the Linux package and installed the latest version of Java from their website however, I have no clue how to make it the default and activate it as opposed to using OpenJDK in Firefox. Any clue on how to make this happen or do I just fall back to Microsoft to get this done?

There is a good walk through for this here.

I was able to disable Open JDK and get java running to where DBsign will start but now gives me the error - "Could not write configuration data: /home/user/.DBsign/UWC/DBsign/cfg (No such file or directory)"

the error code is 138. I am not sure but think it may be something to do with read and write errors in the folder. I changed the parent folder permissions but that didn't help. The new error message is Could not write configuration data /home/user/.DBsign/UWC/DBsign.cfg (Permission denied)

Are you logged in as User user? If so, you also have to chown -R user /home/user/.DBsign/UWC.

The underlying issue is likely that SELinux is blocking this operation.

By default, Mozilla plugins are sandboxed by SELinux and not allowed to write to the file system. The DBsign software, that runs within the Java plugin, needs to create that directory and write its configuration file. SELinux is blocking this from happening.

In order to keep this from happening, you must tell SELinux not to confine mozilla plugins like this:

sudo setsebool -P unconfined_mozilla_plugin_transition 0

If you want to re-enable this setting, do this:

sudo setsebool -P unconfined_mozilla_plugin_transition 1
