Question : Rational App Developer 7 - running as WebSphere 5.1 ?

I have created a web service in Rational and it is running on the builtin WebSphere 6.1
fine.  Can I run it against v5.1 ?  Rational seems to indicate that is contains v5.1 also, but
I can't see how to enable it.  In the "Server Overview" tab, the "Runtime" dropdown only contains
6.1.

Thanks

Answer : Rational App Developer 7 - running as WebSphere 5.1 ?

When you say "can I run it against 5.1?"  Are you asking if you can have a 5.1 WebSphere Test Environment (WTE)?  If this is the case, then the simple answer to your question is:
Yes.

Generally, the follow up question then becomes "how?"

Well, let's back up a little.  When I look in the "runtimes" directory of my RAD 7.0
installation, I see:

 Directory of C:\IBM\SDP70\runtimes

08/01/2007  11:45 AM              .
08/01/2007  11:45 AM              ..
08/01/2007  11:44 AM              base_v51_stub
08/01/2007  11:46 AM              base_v61_stub
08/01/2007  11:45 AM              base_v6_stub
08/01/2007  11:44 AM              express_v51_stub
08/01/2007  11:43 AM              wsdk
               0 File(s)              0 bytes

which shows that I have "stub" directories for 5.1, 5.1 express, 6.0, and 6.1.
Basically, I don't have any WebSphere Test Environments installed.  That's because
I have RAD interact with the WebSphere Application Server installation that is
external to RAD, i.e., it was already installed on the machine before I installed RAD.

I use RAD to develop, and then publish directly to the Application Server environment
that happens to be on the same machine.

When I installed RAD, I told it not to install any WebSphere Test Environments.
Apparently, when you installed RAD, you only asked it to install the 6.1 test
environment.

You should be able to use the Installation Manager to update the available Test
Environments.
