I saw the following exchange over on
news://ibm.software.websphere.application-server.as400 and thought it might
be of interest to some here.

Art responded:

I'm not sure if you intend the java pgm to be run as an application separate
from WebSphere or as an invoked java servlet running within WebSphere.  I
I'd suggest getting this information using java.io.File methods...

If running separate from WebSphere, the java pgm can form the string
"/QIBM/UserData/WebAS5/Base/" + instance + "/config/cells" (where the java
would have to somehow know the WebSphere instance).  It is possible for you
have installed multiple instances of WebSphere on your iSeries, so your java
can't necessarily assume there will be only one instance.

If running as a servlet, it can issue:
    String baseDir = System.getProperty("user.install.root");
to get the String for --->   "/QIBM/UserData/WebAS5/Base/" + instance    -
you can use to append "/config/cells".

Then it is a matter of interrogating its contained subdirectory name, which
should be POSTMASTER_WAS50 on your system.
