1. Create a staging directory and extract the files from opensso.war. For example:
mkdir /tmp/idpdiscoverywarstaging cd /tmp/idpdiscoverywarstaging jar xvf /downloads/opensso/deployable-war/opensso.war
2. Run the createwar.sh script to create a IDP Discovery Service WAR file named idpdiscovery.war.
You must execute createwar.sh (or createwar.bat on Windows) script in the deployable-war directory.
cd /downloads/opensso/deployable-war ./createwar.sh -s /tmp/idpdiscoverywarstaging -t idpdiscovery -w /tmp/idpdiscovery.war
3. You are now ready to deploy your new WAR, as described in After You Finish Creating a Specialized WAR.
