I played a lot with Oracle Service Bus (OSB) in the last few weeks. You will soon know why; no, I can't say right now. I installed it inside an Oracle Enterprise Linux virtual machine, and I must say the installation process is straightforward: install OEPE, install WebLogic, run RCU, run the installer, create a domain... It was nothing special, until I started the Service Bus IDE (OEPE with the OSB plugins). I got the following error messages:
My VM had all the prerequisites listed in the documentation installed. What was wrong, then? Turns out I had used the 64-bit version of Oracle Linux, and the IDE wanted some 32-bit dependencies. To fix the problem, I issued the following commands as root:
yum install ncurses-libs.i686 libstdc++.i686 libgcc.i686
yum install zlib.i686 zlib-devel.i686
After that, the IDE started like a charm. Expect a few OSB-related posts from me in the future!
