Re: [tcf-dev] Adding value-add server

["Oberhuber, Martin" <Martin.Oberhuber@xxxxxxxxxxxxx>]

Hi Vladimir,

The Target Explorer has code that can setup the communication chain for you, it can even launch the value-add for you when you connect the agent. But you need to tell is some details (eg location of the value-add executable). This is done by registering an extension and writing a tiny bit of Java code (ValueAdd / ValueAddLauncher). That bit of setup also helps "hiding" value-add peers which you don't want to see in Target Explorer directly.

Our team is currently working on updating the docs, and your questions are very helpful for us to understand the gaps. I hope to be able and give you some more details early next week.

The Econ 2009 Tutorial has a commandline example on slide 52, which I also demoed live at that time; the commandline example might help you understand what happens under the hood. You can also use that to manually setup the communication chain, by launching the value-add on commandline. If you launch it with "-i" flag ("interactive") you can enter the "tcf Locator redirect" command on the commandline of the value-add. Then what you do in the UI (debugger, RSE, other client) is connect to the value-add-peer instead of the real agent but you can execute any command on the agent (through the value-add).

I hope that this rough outline helps a little for now, feel free to ask any more questions and we'll do our best to answer next week.

Thanks,
Martin

Martin,

thanks for response. But I think I'm still missing something. If I run agent from that directory I can debug, everything is fine.
If I also run valueadd binary it adds another agent in "System Management" view, but it's not clear to me what I can do with it.

The source code say:

	it supports Locator.redirect command, which can forward TCF traffic to other TCF agents.

but how would I issue such command from Eclipse? When I click on this value-add server, it gives me a page of properties, and nothing looks like a redirection. One of the attributes say "Proxy", but I would not expect that underlying agent be called proxy and I would not know what to enter in this field either.

What am I missing?

Thanks,
