The port that your web-application is listening to is specified by $JBOSS_HOME/server/$CONFIG/deploy/jbossweb-tomcat.sar/META-INF/jboss-service.xml, usually this is set to 8080 per default. The servlet context is specified by application.xml and the path is specified by web.xml in the web-application. If you are using the SCAM controller framework (scamController), the URL may look something like:
http://www.yourhost.org:8080/portfolio/main
where 'portfolio' is your servlet context and 'main' denotes the path, which is exactly the case with scamPortfolio.
Use Administer.createManifest(String id) or the corresponding HTTP command to create a Manifest. Only administrators are allowed to perform this operation.
