From: gk on 30 Jun 2010 03:52 Its very much confusing that how many type of messages JMS supports . I have read it can support ObjectMessage , MapMessage , TextMessage , ByteMessage,StreamMessage etc . I'm not sure how many are still there . Is it true that JMS can support any message type ?Could you please throw some light on the type of messages.

If you want to help , could you please post the relevant link instead of the entire API. I don't understand your post.

One of them is the Message interface, used by JMS. If you have already read about JMS, you should know that. Surprisingly, this interface is in the package javax.jms. So if you click on the link I gave you, browse in the upper left frame until you find javax.jms, click on the link, find the Message interface in the bottom left frame and click on the link, you'll find the entire documentation for the javax.jms.Message interface. And surprisingly, the various types of messages are described in this documentation page. A bit of googling would have led you to this page as well : http://download.oracle.com/docs/cd/E17477_01/javaee/5/api/javax/jms/Message..html If you don't know what RTFM means, then read http://en.wikipedia.org/wiki/RTFM JB.

I found all types of messages explained there . Thats very nice . I liked that . However, Could you tell when do we need ByteMessage ? Is it used at all anywhere ? I see TextMessage , MapMessage,ObjectMessage are quite useful . these can cover all sorts of requirement I believe. I don't understand the use of ByteMessage at all . Is it redundant now ? or Still is in use ? If could tell me a simple example where this could be of use that will just wonderful . I did not find any concrete use of this . Could you please explain this part ? |
