Minor Description
If you want to test the IDP, you have to build it with Maven and then deploy it to a pre-configured Tomcat instance with certificates etc. To reduce time in setting all that up, the jetty maven plugin can be used to deploy the idp and optionally the sts component.
The IDP can be started with:
mvn -Pstandalone,realm-a,sts
If you test the REST/JPA layer, you don't have to start the sts as well (profile 'sts').
If you test WS-Federation with the IDP, you must start the sts as well.
The profile 'standalone' means to start jetty embedded. You can launch both profiles in two different shells (but you must not run 'clean') otherwise you remove the war, db files of the other IDP.
The following properties are supported idp.https.port, idp.http.port
Default port for profile 'realm-a': 9443, 9080
Default port for profile 'realm-b': 12443, 12080
