Installing Infocenter on WebSphere 4.0.3 AE causes an exception by starting the application. Running it on the Single Server AE (known as AEs) works ok. Simulated on Windows 2000, AIX 4.3.3 and RedHat 7.3 OS.

The problem is real. The URLProvider setting do not seem to work in the WAS 4 AE. We are investigating it further, but it seems like a Websphere bug. In the meantime, a solution is to add eclipseurl jar to the server VM classpath and not set any URLProviders. This fixes the problem, and works in both AE and AEs. I will update installation instructions, since this is simpler setup than setting three URL providers.
Updated the instructions in 2.0.1 and 2.1 streams. Will appear in the next builds.
Will mark the bug as fixed, since Infocenter works according to the updated (fixed) instructions. We cannot determine whether URL Providers work in WAS, but do not really need to use this feature of WAS.
