Error running WebCenter Tutorial

Question

Hi,
I am trying to go through the WebCenter tutorial Oracle® Fusion Middleware Tutorial for Oracle WebCenter Developers 11g Release 1 (11.1.1)
I have installed JDeveloper Studio Edition Version 11.1.1.4.0 and added the WebCenter Extensions.
I created the tutorial portal application and tried to run it (as per the tutorial but get the following error:
03:10:07 PM] Deploying Application...

The environment in Oracle Enterprise Linux 64 bit running in VMware Workstation 7 and is a clean install with a clean install of JDeveloper.
The other thing I noticed is that on the JDevelopers "Extentions" tab there is a warning:
oracle.webcenter.app
Warning: Classpath entry /d01/oracle/javahome/jdk/lib/tools.jar not found.
I do not know why it would configure /d01/oracle/javahome/jdk/lib as that is not a valid path in the installation.
The full stack trace is:

Hi Peter,
Fixed the problem, I created directories:
/d01/oracle/javahome
and
/d01/oracle/javahome/jdk
then created a symbolic link:
ln -s /d01/oracle/middleware/jdk160_21/lib /d01/oracle/javahome/jdk/lib
When I restarted weblogic it got beyond that but then failed due to "to many open files"
So I edited /etc/security/limits.conf
adding the lines:
oracle hard nofile 4096
oracle soft nofile 4096
as per the weblogic installation guide
The tutorial application then started ...
Thanks for the responses
