[Eric Clayberg]

The exception you are seeing...

Code: Select all

java.beans.IntrospectionException: Modifier for getter method should be public.
    at java.beans.PropertyDescriptor.setReadMethod(Unknown Source)
    at java.beans.PropertyDescriptor.<init>(Unknown Source)

...is caused by a known bug/limitation in IBM Java.

I would suggest trying this with Eclipse running the standard Sun JVM. It should work fine there.
