Before installing the SAML v2 Plug-in for Federation Services into an instance of Sun Java System Access Manager, you need to copy the amserver.war (located in /AccessManager-base/product-directory/) into a new directory and extract its contents using the following command:
jar —xvf amserver.war
This new directory is referred to as the staging directory and contains the original contents for your Access Manager application. Any modifications to the application must be made to the files in this directory. These files are then repackaged into a new WAR and redeployed into your web container. The path to this directory is the value used for the STAGING_DIR variable in your installation file.
If your instance of Access Manager has been customized, be sure to copy and extract the updated WAR.
