List the contents of the directory.
On UNIX platforms, use the ls —l command.
Remove the following older JAR files: jsftemplating-dynafaces-0.1.jar and jsftemplating.jar
Rename the newer jsftemplating-dynafaces-0.1-1.0.jar and jsftemplating-1.2-SAILFIN.jar as jsftemplating-dynafaces-0.1.jar and jsftemplating.jar, respectively
Restart the domain and log into Admin Console.
