Oracle SOA Suite 11g Technology Preview - Configuration Hint

I was recently configuring Oracle SOA Suite 11g on my computer and I have faced configuration related problem. Want to describe it and give hint how not to face it.

Problem description:

1. SOA Suite configuration is failing with message - Configuring SOA Infrastructure has FAILED

2. In startsoa.log there are only two strange lines printed:

java.lang.NoClassDefFoundError:
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 \jdev\bin\jdev.boot file and change value for ide.user.dir variable.

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.
