A drag and drop GUI confi

Show all headers | View raw

  To: comp.lang.java.gui
I'm very comfortable in J2SE, and need to create a user interface to a
back end program that has no interface itself, running in a J2EE
container. This is a client app that needs to:

1. Be used to configure the back-end software by creating XML config
files, and triggering actions via web services calls from the client
to the server. This would be via a drag and drop GUI, with the
software components being brought into the work area. Then these
components would be connected to each other the same way that
connectors in PowerPoint work.
2. Right clicking on either a component or connector needs to bring up
a context menu allowing that software component to be configured.
Eventually you have a field in the GUI with little boxes in it that
have lines connecting them.
3. This same GUI would then reflect the actual operation of the
underlying software. This means the same GUI is used to configure as
well as monitor/mange the application. The boxes and connectors would,
say, change color based on their operation/performance on the J2EE
server. Once the context menu is brought up, things like graphs can be
displayed showing that component's performance, metrics, etc.
4. If it helps, think of this client interfacing with the server
solely via web services. This doesn't affect the product I'm looking
for, as I'd write all the WS client stuff anyway.

I'm good with all of this, except the part where the user drags &
drops the components into an empty work area. I don't know if I can
write such functionality from scratch, but I haven't turned up any
products that fit the bill. I'm definitely assuming a J2SE app on the
client side.

So the question is: Do you know of any software components available
for Java that allow/facilitate this? Or is this something I can do
today in Java from scratch (yikes!)?

TIA!
