[jboss-user] [Installation, Configuration & Deployment] - Unable to set JBoss server from within Eclipse.

[cybercollege]

Please help me in solving the error I am getting. Please refer to the explanation below:

The have installed the following:

JAVA SDK: 1.5.0_12
Eclipse: 3.2.2
JBOSS: 4.2.0
JBOOS Plug-in for Eclipse: 1.6.0.GA

In Eclipse, when I go to RUN -> Debug..    I see JBoss2.4.X to JBoss 4.0.x
I don't see JBoss 4.2.X. Should I select 4.0.x? If I select any on the JBoss2.4.X to JBoss 4.0.x, I get the following error:

Problems occurred when invoking code from plug-in: "org.eclipse.jface".
