Code setup to use WebSphere APIs

[Syed Hasan]

I am trying to write some code using WebSphere APIs
specifically trying to get a list of application Servers.
I believe I have not set things up correctly in WSAD as I am
getting an exception in the first line of code. Any ideas on what I
need to do to get this code to work. Thanks.

}/*

}

public Vector getInstalledApplications()
{
Vector appsList = null;
try
{
Hashtable prefs = new Hashtable();
prefs.put(AppConstants.APPDEPL_LOCALE, Locale.getDefault());
appsList = appMgmt.listApplications(prefs, null);
}
catch(Exception e)
{
System.out.println("Problem Admin");
}
return appsList;
}
public static void main(String [] args)
{
try
{
CRoot root = new CRoot();
System.out.println(root.getInstalledApplications().toString());
}
catch(Exception e)
{
System.out.println("Wassup" + e.getMessage());
}
}
}

Any help will be much appreciated.
