JP1 Remotes

Tried running RM 1.65 under Linux FC5 and get the following at the end of the rmaster.err file. Can anyone help?

Exception during event dispatch:

Looks like you have an old version of Java.
javax.swing.text.NumberFormatter was introduced in Java 1.4.
RM requires Java 1.5

RM requires Java 1.5

Thanks, I'll check that and let you know, although, I was sure I was running 1.5

edit:
I did have Java 1.5, but it wasn't in the path. Expliciting pointing to Java 1.5 solved the problem.

Thanks again
