WebLogic JNDI Custom Resource Configuration

I have been using WebLogic for a couple years now. While it is better than Oracle Application Server, it is missing some very important functionality. Today's complaint is the lacking of a way to add custom JNDI resources. This was discussed at stackoverflow: Custom resource in JNDI on different application servers. I am currently using Oracle WebLogic 10g (10.3.5), so my solution may not be relevant in future versions.

Mapped Diagnostic Context (MDC) in Weblogic 10.3.5

Problem: Mapped Diagnostic Context (MDC) values aren't available in Weblogic 10.3.5 Logs

I am developing a web application that is deployed on Weblogic 10.3.5 and I am using SLF4J for logging. I used the Mapped Diagnositc Context (MDC) feature of SLF4J to include the current user and the current remote IP for each log message.

[2012-03-02 12:56:29,770] INFO  ii.green.phillip.ImportantClass - IP[127.0.0.1] - UserName[pdgreen] - Info Message

I use a servlet filter to set the MDC values and everything worked just fine when I used log4j or logback as the SLF4J implementation. While the logs look fine with a file appender, they don't show up in the Weblogic logs when I use the console appender.
