[opencms-dev] Blank screen comes when trying to access the workplace

[Ravi Subramanian]

Hi ,

I downloaded OpenCms and installed it. I am using tomcat 5.5.23 and
mysql 5.0.45. 

I followed the setup wizard for installing OpenCms. I installed all the
modules that it included by default.

When i login and access the workplace i get a blank screen. I turned on
the log level to debug and got the following message stating that it is
unable to read resource "/system/workplace/index.jsp".

The following were the contents of the log

I also found the following thread saying that workplace returned a blank
screen. 
http://mail.opencms.org/pipermail/opencms-dev/2006q4/027191.html
It says that there was a module which had some conflicting jar files. I
did a search for those jar files and nothing was found. 

Someone help me with this please.

Regards,
Ravi.
