Ok, now it works again. I removed the folder /home/peter/.java/deployment and all its subdirectories, and also the folder created by running JSynthLib: /home/peter/.java/.userPrefs and all its subdirectories. Now I can open the preferences window again, and JSynthLib version 0.20.0 doesn't give an error dialog anymore, also not on the first time I loaded it. It just creates the .userPrefs folder with the *.user.lock.peter* and *.userRootModFile.peter files* and org folder containing a prefs.xml file and hte rest of subdirectories and prefs.xml files.
In case it's of any use, I think the file /home/peter/.java/deployment/deployment.properties was responsible: #deployment.properties #Sat Aug 22 16:04:09 GMT 2009 deployment.javaws.splash.index=/home/peter/.java/deployment/cache/6.0/splash/splash.xml deployment.trace=true deployment.log=true deployment.javapi.lifecycle.exception=true deployment.version=6.0 deployment.browser.path=/usr/bin/mozilla #Java Deployment jre's #Sat Aug 22 16:04:09 GMT 2009 deployment.javaws.jre.1.registered=false deployment.javaws.jre.1.osname=Linux deployment.javaws.jre.0.registered=true deployment.javaws.jre.0.platform=1.6 deployment.javaws.jre.1.enabled=true deployment.javaws.jre.1.location=http\://java.sun.com/products/autodl/j2se deployment.javaws.jre.0.osname=Linux deployment.javaws.jre.0.path=/usr/lib/jvm/java-6-sun-1.6.0.15/jre/bin/java deployment.javaws.jre.0.product=1.6.0_15 deployment.javaws.jre.1.osarch=i386 deployment.javaws.jre.1.path=/usr/lib/jvm/java-6-openjdk/jre/bin/java deployment.javaws.jre.1.platform=1.6 deployment.javaws.jre.0.osarch=i386 deployment.javaws.jre.1.product=1.6.0_0 deployment.javaws.jre.0.location=http\://java.sun.com/products/autodl/j2se deployment.javaws.jre.0.enabled=true deployment.javaws.jre.0.args= I guess I've messed up that file by installing too many different java versions: sun-java, openjdk, and different versions ... Finally I can go back to writing my driver :-) Happy summertime ;-) Peter On Tue, Aug 25, 2009 at 11:27 AM, Peter Geirnaert <[email protected] > wrote: > Hi again :) > > Maybe this is information I should also give ... > > When I start JSynthLib, it creates two empty files in > /home/peter/.java/.userPrefs/ : > *.user.lock.peter* and *.userRootModFile.peter* > > Questions I have here: > 1.
