Configuring Exception Handling
By default, PTC FlexPLM displays a generic message for out‑of‑the‑box exception handling. You might want to disable this functionality when configuring a development or test environment.
* 
This functionality is only intended to be disabled in a non-production environment. It is not a good practice to display error messages that contain sensitive system information to anyone other than system administrators who have access to application logs.
To disable generic error messages, follow these steps:
1. Open the <Windchill>/codebase/custom.lcs.properties file for editing.
2. Add the following property setting:
jsp.exception.GenericExceptionPage.enabled=false
3. Go to the <webserver>/conf/conf.d directory.
4. Rename the 30-app-RFA-ErrorDocument.conf file to app-RFA-ErrorDocument.txt.
When renaming this file, you can use any file extension other than .conf to stop inclusion of this file. To revert the changes, change the file back to the original name.
5. Restart Windchill and the web server, and make sure that they are up and running.
