My organization previously used ASP.NET for web projects.
They are now migrating to WebLogic Portal/JEE for all future web projects.
My experience as a Lead Developer / Architect is totally with .NET projects. I want to get ramped up on WebLogic/JEE, so I can contribute to future projects.
Any training/certification suggestions for WebLogic/JEE, in a 6-month time frame?
Assume that I will need to fund my own training, and I am working full time. So, money and time are limited.
Oracle conducts many trainings for Weblogic development, administration. It depends on your needs - do you need basic J2EE and Web services on Weblogic Server, or Portal development on Weblogic Portal, or EAI/JMS learning on the Aqualogic middleware set of products.
These are expensive (think 3000 USD per course)
My suggestion would be to read the fundamentals of Java and J2EE from the sun website http://java.sun.com/javaee/reference/tutorials/ and get hands-on with the syntax and concepts. Learn the variations between .NET and Java world.
After that, the organization might finalize what versions/products they need to use from the vast Weblogic set. You can download trial software and even pick up from the OOTB tutorials available in Weblogic.
