Immediate answer--you can't. Java don't let you access to Windows message queue. There is java.awt.EventQueue class and java.awt.Toolkit.getSystemEventQueue() method which allow such low level manipulations with java event queue. You also can use JNI to call Win32 functions.

Can you provide more details? Why do you think you need sendMessage() or postMessage()?

Hmm. Are you speaking of the Swing Event Queue? Sounds like a job for the SwingUtilities class -- either invokeAndWait or invokeLater. Both methods take a Runnable, that is, an object of a class which implements the Runnable interface. The run method will be the action that you want to post on the Event Queue. You can find more detailed information in the following articles on the Swing Connection at the JDC:

Or perhaps you are talking about some other kind of queue?
