1. SOA Suite configuration is failing with message - Configuring SOA Infrastructure has FAILED
2. In startsoa.log there are only two strange lines printed:
Exception in thread "main"
And no more information about problem :-)
Ok, I have found solution in Release Notes for SOA Suite 11g Technology Preview 3 update 1. It seems problem was in spaces in JDEV_USER_DIR path. In order to change home directory you need to open
After those changes, I configured Oracle SOA Suite 11g Technology Preview successfully.
Complete Guide for Oracle SOA Suite 11g Technology Preview configuration you can get on OTN.
