Thanks for the info. OK i installed a java runtime and invoked the command in the Phex directory here is what I get

java.lang.NoClassDefFoundError: javax/swing/JWindow
at java.lang.reflect.Method.invoke0 (Method.java)
at java.lang.reflect.Method.invoke (Method.java:255)
at kaffe.jar.ExecJarName.main (ExecJarName.java:67)
at kaffe.jar.ExecJar.main (ExecJar.java:75)

I used the command as you suggested

java -jar phex.jar and this is the response. Any ideas?

Thanks
