Create a manifest file for your specialized OpenSSO Enterprise WAR, as described in Creating an OpenSSO Enterprise WAR Manifest File.
Note: Create the manifest file based on the original OpenSSO Enterprise 8.0 opensso.war, as delivered from Sun, prior to any customizations you might have done. If the manifest is created after customizations, ssopatch might use the files from Update 1, rather than your customizations, so you would need to re-do your customizations after patching.
Generate the specialized OpenSSO Enterprise WAR from the OpenSSO Enterprise 8.0 Update 1 opensso.war file, as described in Chapter 4, Creating a Specialized OpenSSO Enterprise 8.0 Update 1 WAR File.
Use the ssopatch utility to compare the your old and new WAR files.
Generate a staging area for the new specialized WAR file, as described in To Create a Staging Area to Patch an OpenSSO Enterprise WAR File.
Redeploy the new specialized WAR file.
