If you are using Oracle Application Server, you must uncomment one entry in the Cognos dispatcher properties file. You must make this change before deploying Cognos components or problems will occur when running Cognos applications.
In a text editor, open the c8_location/webapps/WEB-INF/p2pd_deploy_defaults.properties file.
Locate the following entries:
#set this to true to wrap the input stream so that Oracle Application Server will parse the XML properly #wrap_input_stream=true
Uncomment the second entry by deleting the pound symbol (#), as shown here:
wrap_input_stream=true
Save and close the file.
