I have commited a new jrStepGUI release.
It pops up an error dialog when the RXTX native library is not found.
This may help if you have troubles running the RXTX library:
> Download the latest jrStepGUI version and put it in any directory.
> Rename the just downloaded file as jrStepGUI.jar.
> Create a subdirectory called lib.
> Copy the native library (e.g. librxtxSerial.jnilib) in the lib directory.
> Open a shell, go to the directory where you downloaded jrStepGUI and type:
> java -Djava.library.path=lib -jar jrStepGUI.jar
> If jrStepGUI still pops up an error dialog, take a look to the displayed java.library.path property value and try to copy the native library into this path.
The compiled version is available at:
