So, you've already started Postcard with a nickname, which we'll call "Will", and you want to send a postcard to a second nickname on this computer. Here's how to do it:-
Move this Postcard to one side of your screen, then start a second Postcard by running the JmsPostcard shell script again.
Enter your second nickname, which we'll call "Tim".
Now on Will's Postcard fill in the To field with your second nickname, Tim. (You can leave the On field empty and Postcard will fill it in for you, or you can type in the queue manager name that you see below the Message box after "On:").
Click in the Message box, type your message in, and click the Send button. Look in Tim's Postcard to see the message arrive, and double-click on it to see the postcard itself.
Now try using Tim to send one back to Will. You can do this easily, by selecting the message that arrived in Tim's list, and clicking the Reply button.
The Postcard needs a suitable queue manager to act as mailman. The default configuration is the easiest way to get one. You will be prompted to install the default configuration the first time you start Postcard. You are recommended to take the defaults - it doesn't take long.
Instead of the default configuration you can also start Postcard on any other local queue manager.
If you want to send postcards to another computer, the default configuration must include the option of being joined in the same cluster, or if you are using other queue managers they must either be in the same cluster or you must create a connection explicitly between them.
