Lingo supports JMS implementations of Java 2 Collections. For example the JmsQueue class implements the BlockingQueue interface from Java 5 (using backport-util-concurrent currently).
This allows you to use the familiar Queue interface from the JDK with POJOs and hide the JMS code.
Under the covers iterating through the collection & querying it is equivalent to using a JMS QueueBrowser. Removing from the queue will actually consume the messages. So you can have multiple threads and multiple processes consuming and adding to the queue concurrently.
