3. Add Operation .. 5x5


Right-click to reveal the menu, and select Control Flow

Searched again..

when creating the Hello World Behavior in Step 4, you need to add an “activity final node”, which you will find by right-clicking the block → Add… → Activity Final.
(All activity nodes are described here:

An edge can be either a control flow or a object flow. So add an edge by right-clicking the block → Add… → Edge.
You will find more about activity edges here:

Have you created the same behavior as shown in the screenshot of the tutorial (within Step 4)?

The output when running Hello World looks rather rare. There is no javax.jms…. involved in the Hello World system. Have you chosen “Java Standard Edition” in the platform dialog when building the application? Did the …helloworld_exe project in the Package Explorer look ok (no red errors)? Have you chosen “Run As/Java Application” when running the …_exe project? Have you chosen the right java application (something like Start – my.project.helloworld) when asked to Select Java Application?

I guess we need some more input from you to figure out what has happened :)
