Creating node connections with the mouse

Before you start:

Read the concept topic about connections.

To connect one node to another using the mouse:

  1. Switch to the Broker Application Development perspective.
  2. Open the message flow that you want to work with.
  3. Click Connection above the node palette.
  4. Click the terminal from which the connection is to be made, that is, the terminal from which the message is propagated from the current node. For example, you can click the failure terminal of the MQInput node, or the out terminal of the Compute node. You do not need to keep the mouse button pressed. If you are unsure which terminal is which, hover your mouse over each one; the terminal is highlighted in blue and a pop-up displays the name of the terminal.
  5. Move your mouse and click again when the mouse pointer is above the in terminal of the next node in the message flow (to which the message now passes for further processing). The terminal is highlighted in blue and a popup displays the name of the terminal so that you can check that you have the correct terminal. The connection is made when you click on a valid in terminal. The connection appears as a black line between the two terminals.
In the Message flow editor you can display node and connection metadata by hovering the mouse over a node or subflow in a message flow. To view metadata information for a node, subflow or connection:
  1. Open the Broker Application Development Perspective
  2. Open a message flow
  3. In the Editor view, hover the mouse over a node, a subflow, or a node connection in the open message flow by placing the mouse over the element.
