While trying to run a java app (specifically, NeurosDBM[1]),
I get the following error:

me at myhost:~/ndbm$ gij -jar NeurosDBM.1.49.jar
Exception in thread "main" java.awt.AWTError: Cannot load AWT toolkit:
   at java.awt.Toolkit.getDefaultToolkit(
   at java.awt.GraphicsEnvironment.getLocalGraphicsEnvironment(
   at net.sourceforge.neurosdbm.NeurosDBM.main(
Caused by: java.lang.UnsatisfiedLinkError: libgtkpeer: cannot 
open shared object file: No such file or directory
   at java.lang.Runtime._load(

Based on the error message, I searched for 'gtkpeer' in 
Adept, found classpath-gtkpeer, and installed it. No change. 
Any suggestions appreciated.

(By the way: what's the kubuntu equivalent of 'rpm -qa'?)
