Oracle Service Bus 11gR1 IDE Eclipse OEPE installation on Windows 7

Follow these steps to setup a development environment for Oracle Service Bus 11gR1 (11.1.1.6 is used in this example)
Download these components:

  • Oracle WebLogic Server 11gR1 (10.3.6) and Coherence and OEPE for Windows (32-bit) (Part Number: V24367-01)
  • Oracle Service Bus 11g (11.1.1.6.0) (Part Number: V29756-01)
I could not find these files through the Oracle.com website but you can download previous versions through the Oracle Software Delivery Cloud. These two installation files can be found in this category:
Product Pack: Oracle Fusion Middleware
Platform: Microsoft Windows (32bit)
Choose media pack: Oracle Fusion Middleware 11g Media Pack for Microsoft Windows (32-bit) 11.1.1.6.0 (Part number: B55383-41)

(Tip: Search for the Part numbers to make sure you download the correct versions)
First, install WebLogic Server with Oracle WebLogic Server 11gR1 + Coherence + OEPE and then install Oracle Service Bus.
When you install OSB, be sure to select the OEPE that is located inside the middleware directory.
After both installations, in the directory “Middleware directory/oepe_11gR1PS2” is eclipse.exe. If you execute this file, you can open Eclipse and start with creating an osb project.
Side note;
Some people can’t see the OSB perspective in Eclipse after this installation. Apparently it’s a rights issue which can be solved by navigating to the Oracle_OSB directory via Windows Explorer. You will be asked for permission to access that directory and after that dialogue you will be able to open the OSB perspective within Eclipse.
