cd AccessManager-base/ SUNWam
This is the directory in which the WARs are kept.
jar -uvf WARfilename.war < path_to_modified_file>
The -uvf option replaces the old file with the newly modified file. For example:
jar -uvf console.war newfile/index.html
replaces the index.html file in console.war with the index.html file located in AccessManager-base/SUNWam/newfile .
Delete the modified file.
