Jdeveloper TP4 and integrated SOA Server

Download Jdeveloper Technology Preview 4 from OTN. Unzip the package in your system in such a way that there are no spaces in the path.

For ex. c:\Softwares\Jdeveloper 11g\ ------ this is incorrect
Make sure that java is also installed in a location where there is no spaces in the path.

Download and install Oracle Database XE if don't have one running on your system. You dont require a database if you are not going to configure SOA in the integrated oc4j server.

Follow the instructions mentioned in this pdf to set up the Integrated oc4j server with SOA configured. Before doing this edit \jdev\bin\jdev.conf and remove or comment the last AddVMOption. If you dont do this you wont be able to see the Configure SOA option in the Tools menu.
