Weston: I can't tell you how thankful I am for you help!!!!!! Okay, what I did was changed the driver portion of my -ds.xml file. I also verified that I had only one -ds.xml is in the directory. I removed the 3 jar files I using for the SQL Server and replaced it with the new jar file sqljdbc.jar file. When I re-start the server with the correct driver name, I get the below error: | 13:24:00,141 INFO [WrapperDataSourceService] Bound ConnectionManager 'jboss.jca:service=DataSourceBinding,name=jdbc/pidbdev' to JNDI name 'java:jdbc/pidbdev' | 13:24:00,188 WARN [JBossManagedConnectionPool] Throwable while attempting to get a new connection: null | org.jboss.resource.JBossResourceException: Could not create connection; - nested throwable: (org.jboss.resource.JBossResourceException: Class not found for XADataSource com.microsoft.jdbcx.sqlserver.SQLServerDataSource; - nested throwable: (java.lang.ClassNotFoundException: No ClassLoaders found for: com.microsoft.jdbcx.sqlserver.SQLServerDataSource)) | Do I have the right version of SQL Server Driver? I was under the impression I did when I swapped out. Thank you for taking the time to explain this to me.
