I have the following configuration: MQWF3404 on AIX5.2. Two configurations: DEV and TEST (DEV is default). For each config, I have deployed the default WebClient to WAS5.02 in server1.

The problem is in running the WebClients. Which ever one I try first works without a hitch. The one tried second gives the following:

java.lang.UnsatisfiedLinkError: Native Library /usr/lib/libfmcojprf.a already loaded in another classloader.

Does anyone know how to configure WAS or the WebClient so I can run both? I can always spin up another app server, but that adds pretty substantially to the overhead on the box.

Thanks.

1. Change the WAS server's 'Application Classloader Policy' to 'single', which allows the Web Client's native library to be loaded only once even the Web Client is restarted.

OR

2. Make the Web Client's jars/classes available at the WAS server level, that is, set the classpath for the WAS server to point to the Web Client's classes/jars. But these classes/jars should be available in a directory NOT under <was>/InstalledApps. Refer to web link for detailed information:
