If you have just migrated a JMS based project from Java CAPS 5.1.x to Java CAPS 6 and have taken the Environment (unchanged) as well you may see the following appearing in you Application Server Log file and the JMS Fails.

RASTCMS-E307: No port specified in URL [stcms://]

This is caused by a change in the way Java CAPS 6 Glassfish installation treats the JMS Server. In the Java CAPS 6 release the concept of a default JMS server is no longer appropriate because multiple servers can be installed with the Glassfish instance. The net result of this is that the Java CAPS 5.1.x default JMS URLs (stcms://) are nolonger valid.

The resolution to this is quiet simple you will need to edit your JMS Server properties and change the URL to stcms://localhost:18007. This change will resolve the issue and cause the Java CAPS 6 application to behave in the same way the Java CAPS 5.1.x one did, assuming that you are using the default JMS ports.
