Problem With LOGON.par

Question

HI
iam using NWDS 2.0.12 version as indicated i have moved the par file into the studio and edited the jsp tages according to my needs by  the system is showing the error
Portal Runtime Error
An exception occurred while processing a request for :
iView : N/A
Component Name : N/A
The exception was logged. Inform your system administrator..
See the details for the exception ID in the log file
The foloowing steps i followed
The login page is part of the par file with the name com.sap.portal.runtime.logon.par
1) Copy the file with the above name from the following location (EP6 SP9 and higher). It has the additional ending ">\<SID>\<Instance>\j2ee\cluster\server<#>\apps\sap.com\irj\servlet_jsp\irj\root\WEB-INF\deployment\pcd\
2) Import the PAR file into Netweaver Developer Studio:
3)Edited the file
4) while importing the lib directory was empty so i copied the files
1. com.sap.portal.runtime.logon_api.jar
2. umelogonbase.jar
into the lib directory
5) after that i made a par file using nwds and winzip.
6)Then i changed the authescemes .xml file
1. Start the Config Tool by executing <SAPJ2EEEngine_installation>\j2ee\configtool\configtool.bat.
2. Navigate to cluster_data>server>persistent>com.sap.security.core.ume.service.
3. Switch to edit mode by clicking on the pencil which is at the upper right area.
4. In the tree, select authschemes.xml and choose Download. Save the file to your local directory
5. Edit the local file: To select the new PAR file as the Logon page change the occurrence of all substrings com.sap.portal.runtime.logon to your
project/PAR file name. All com.sap.portal.runtime.logon should be substituted with something like com.company.portal.runtime.logon (or whatever you project name is). Don’t remove the part behind it.
(These are the profiles in the portalapp.xml and have the names default, certlogon, basicauthentication, header, and anonymous).
6. Create a new node in the configuration tree in the Config-Tool for the edited file as follows:
a.Select the node com.sap.security.core.ume.service.
b. Choose the symbol for Creating a node below the selected node.
c. Select the type File-entry.
d. Choose Upload and select the custom file from your local directory.
e. Enter a name for the entry, for example, authschemes_myHR.xml. By default, the name of the uploaded file is used.
f. Choose Create.
g. Choose “Close window”.
h. The new node appears in the configuration tree.
i. Go to Global server configuration>services> com.sap.security.core.ume.service and edit the property login.authschemes.definition.file.
The value needs to be changed from authschemes.xml to authschemes_myHR.xml
j. Restart the Portal. That is often not done and the changes will not appear.
after doing all this the portal shows an error
can anyone tel me where am i going wrong what steps iam missing while changing the par file.aslo pls if any one can tel me where exacty the log file is stored and how do i check the exception id.

Hi Pankaj,
The steps seem to be correct.
The physical location of the log file is:
\usr\sap\<instance name>\JC01\j2ee\cluster\server0\log
You could check in the defaultTrace files here. Also note that the log entry could go into the Trace files in one of the Server in the clusters.
You could also look for the Log file from within the portal using Java Home-> Portal Log Viewer -> give the Exception id in the search
