I'm new in this community and my question is the next.
Using oracle's OEPE to work with the OSB projects, it doesn't allow me to create an OSB project or an OSB Configuration Project. I have tried installing the plugins for the 11.1.8 version, downloading turmeric SOA plugin from the marketplace and manually load the plugins from oracle.
How should I proceed to access the OSB Functionality?
You can't just download the OEPE from internet and start doing OSB development. It won't show you the OSB perspective option.
You need to install the OSB from Oracle site first. During installation it will ask for the OEPE path and will add required OSB plugins in it. After installation is done you will be able to see the OSB related options in OEPE.
