Thanks for the quick answer.
Those are really all messages I see on the debug console window. In the "Error Log" view I don´t get any messages at all. Do I need any special debug settings in the ".options" file?
Yes, I followed the instructions: I did not unzip the file but let eclipse "Install new software" handle the zip.
By the way, I was expecting to see something like "JSF tools" among the JBT options during installation. Or is this contained in another tool?
