Okay, I am setting up an application in WAS6.2.5.  In configuring WAS6 I hav
e created several datasources and given WAS6 the location of the classes12.z
ip for Oracle to use.  When I attempt to test these connections I get this m
ysterious error:

Test connection failed for data source Cust Care Datasource on server dmgr a
t node dmgr_wfadc020 with the following exception: java.sql.SQLException: ja
va.lang.IllegalAccessError: tried to access method oracle.jdbc.ttc7.Oversion
.marshal()V from class orac
le.jdbc.ttc7.TTC7Protocol.

I have installed this application using this exact classes12.zip on 6.2.3 be
fore with no troubles.  In searching I cannot find this error in the resourc
es available to me, does anyone out there have any insight?

How did you configure the datasource's jar? Sounds like that may be an
issue. Make sure there isn't a copy of its jar in one of the WebSphere
lib directories.

hi Ken,

You should avoid at all costs putting the any jar files in the WAS_HOME/lib
directory.  You should setup your jar files by simply setting the classpath
entry when defining the datasource.
