If the Access Manager single WAR is generated using the Java Enterprise System 5 installer with the Configure Later option, additional .jar files are required before you deploy Websphere 5.1.
Copy jsr173_api.jar from /usr/share/lib to the AcessManager-base/opt/SUNWam/web-src/WEB-INF/lib directory.
Goto AccessManager-base/SUNWam/bin/ and run the following command:
amconfig —s samplesilent
For more information on configuring Access Manager using the amconfig script, see Running the Access Manager amconfig Script in the Access Manager Post Installation Guide.
