I have seen some examples of T3 working with Azure Load Balancer & weblogic, but there are some limits & special things you need to do.

This template description discusses getting it working. Look for the question titled "WebLogic Server expects public and private ports to be the same for T3 access (for example, when using Enterprise JavaBeans)."

It discusses how to add additional parameters, and to make sure that public & private ports are the same with T3.
