Deploy external jar to WAS 6.40

Hi all,

I'm trying to deploy an external jar file (classes12.jar - an oracle jar). I've followed the instructions on 'defining libraries' found on sdn -http://help.sap.com/saphelp_nw04/helpdata/en/ee/6ede3f7bc1eb06e10000000a1550b0/frameset.htm

But I cannot access the deployed project/jar, although I do see its definition using the visual administrator.

Any help would be appreciated,
