Tutorial for writing resource adapter

[Haris Karameh]

Is there a tutorial with an example which explains how to write resource adapter.My search returned a lot of documents with a lot of talk but not action - not a sigle example of how to. I am trying to use it with IBM Websphere 6.0.
I have to write a custom adapter as I am try to connect to an unusual piece of industrial equipment.
TIA, Haris

Sorry about my username. I registered 3 years ago but did not post. Now, I updated my display name but somehow my login name is still shown

Thanks Haris! Your display name is good now.

Did you check in the WebSphere help or redbooks?

Something tells me that your industrial equipment doesn't support a file system, does it ?

What comm protocol does it communicate with your server ?

I checked redbooks but search turned out nothing usable.
My equipment has custom serial protocol and there is a need to connect the application to OPC server at the same time. I have a pretty much good idea how to do it (it would not be problem for me to write a driver in C), but how to make it Resource Adapter for WS which can be used by multiple users simultaneously - I do not know where to start.
Still looking for help

Here is the link for some source code for Resource Adabtors.
http://j2eeadapters.sourceforge.net/propra.html

I am also writing one for reading xml files and using the code from here as an information.

There are also already available resoure adaptors at this site.

I was trying to google for "resource adapter pattern" and almost at the top of the result list comes this. Hopefully it is of some use to you.
