FileOpenService, uninitialized

I am developing an application using Java WebStart 1.4.2_02

There are two problems:

1) I am using the FileOpenService.

When I run the application in Eclipse, my application
gets an UnavailableServiceException

Caused by: javax.jnlp.UnavailableServiceException: uninitialized
at javax.jnlp.ServiceManager.lookup(Unknown Source)

This exception occurs when I try running the code in the IDE environment (Eclipse 3.0 M9)

How can I resolve this?

2) I want to be able to set debug breakpoints in the application
as it is running inside the Java WebStart JVM.

How can I do this?

Sun's developer documentation and FAQ do not address either of these issues.

For your first problem, it looks like you don't have a *.jnlp file to configure Java Web Start. You will need this file anytime you use web start, otherwise ServiceManager.lookup() will throw an UnavailableServiceException. Check out for more information.
