Standard Oracle Fusion Middleware Installation fails on SOA ManagedServer start due to classpath problems

Trying to install Oracle Fusion Middleware 11gR2 on windows (same thing happens on Linux). I have followed the guidelines provided in the http://download.oracle.com/docs/cd/E12839_01/install.1111/e14318/toc.htm

1. Installing the weblogic (11g)
2. Oracle 11g databse installation
3. Running the RCU utility to create schema
4. Installed and copied relevant files for Java Bridge
5. Configure the Fusion Middleware

But i found that the SOA server is not getting up in the enterprise manager its showing as down. When i checked the logs iam getting the following error:
