[eclipse-users] Can't run the java interface QuickTest

Hey,
After compiling QuickTest.java, with the command javac -classpath
/Users/matt/eclipse/lib/eclipse.jar: QuickTest.java
when I subsequently try and run the quick test I get a Null Pointer
Exception, I figure that I have not set the directory correctly but it is
/Users/matt/eclipse  and I can run eclipse from the command line so im not
sure what is going on.

java -classpath /Users/matt/eclipse/lib/eclipse.jar: -
Declipse.directory=/Users/matt/eclipse QuickTest
Exception in thread "main" java.lang.NullPointerException
