This sample demonstrates the ability to both send and receive strings through the use of the TIBCO StreamBase® Adapters for UDP. Both the sender and receiver adapters are configured on the default port numbers; the feed simulation will work as long as the Receiver port number isn't altered.
In StreamBase Studio, import this sample with the following steps:
From the top-level menu, select→ .
udpto narrow the list of options.

If you see red marks on a project folder, wait a moment for the project to load its features.
If the red marks do not resolve themselves after a minute, select the project, right-click, and select→ from the context menu.
udp_uni_sample.sbappfile and click the Run button. This opens the SB Test/Debug perspective and starts the module.
In Feed Simulations view, select

There will be two copies of each tuple on the Output Streams view, one from each of the receiver output streams.
Next, try selecting the ReceiverControl input stream from the drop-down menu in the Manual Input view. Type
disconnectand click . This closes the connection to UDPReceiver.
Now there should no more tuples appearing on the Output Streams view.
To reconnect, select ReceiverControl and send the command
When done, press F9 or click the Terminate EventFlow Fragment button.
