Portal Runtime Error : An exception occurred while processing a request

Question

Hello friends,
After upgradation of my portal to the following patch level, SAP J2EE 6.20:
<b>Portal Version :</b> EP 6 SP 2 patch 29 hotfix 0
<b>Content Mgmt and Collaboration  version</b> : 6 SP2 patch 5
i faced many performance related issues. Portal seems to be <b>very slow</b>. After logging in, most of the time I get 2 errors:
<b>Either</b>
<b>1></b> Iview remains blank.
<b>Or
2></b> Portal Runtime Error : An exception occurred while processing a request. Portal Runtime exception occured. Please check the System Log.
But when I refresh that particular iview, it works fine.
I went through the portal.log file (/usr/sap/PEP6/j2ee/j2ee_00/cluster/server/managers/log/portal/logs). And found <b>the root cause of most of the exceptions as "com.inqmy.services.servlets_jsp.server.ServletNotFoundException: The requested servlet ( portal ) not found."</b>Aug 18, 2005 6:07:42 PM # PRT-Async 2          Fatal           Exception ID:06:07_18/08/05_0669

Anthony,
  I had check it. It was correct. But the thing when I saw in the component Inspector of portal, my iview did not appear.
I created like this
         project-> rightclick->   export-> par ->selecting project-> givint protal password-> and finish.
The NW didn't give any error, but the par file didn't appear in the portal componet Inspect.
but the par file is  created in the NW studio Navigation bar.
  Let me know any help regarding this
thanks
