Can anyone help me with jms call in c language!
-
Hi,Every one: I just use jms lib to send message to jboss server. And I useing C to do this work. But I doubt there is memory leak when call jms api. I have a test with create one instance of Message and set the message with new text context when sending the message. After send 20000 messages,the memory requirement increase 2000K +. I don't know where I am wrong. So,please anyone can send me a sample with call JMS lib in C language. (include create context,connection ,send message and destroy all instance) Thank you very much! Don't look at me in that way!

JMS, such as Java Message Service (message queues) ?

How are you verifying this?

According to Performence moitor ,I can find it! Don't look at me in that way!

Are you sure that number is not just a "high-water mark?" In other words, like Task Manager, it must just be address space footprint of your module.

I have soled this problem now! I am sure that the number is not the peek value. I use the jms c lib in a multithread program,and whenever I create a text message,the lib will create the context for the message, so memory leaked. And now,I use a work thread to send the message and everything looks fine except re-connect to server.If I re-connect to server due to network issue,it looks leak some memory. Don't look at me in that way!

It sounds like the problem has simply changed location.

Yes！I think . I am testing the program now. Now,it had sent 140000+ messages and memory increased 428K. I want to keep the program running for 4 or 5 days. each days it will send 144000 pieces of messages. And each mesasge has 800 bytes content. Hope it has a peek memory useage! ^_^ Don't look at me in that way!

Are you allocating memory someplace that is not being deallocated?

I use the lib in a simple way as follow: When the application run,I will start a new thread which will be end while application die! In the new thread I will check if there is any message in the message stack.If so,send it using JMS lib.or else,just wait a short while. The stack manager was written using STL. And I haven't allocate any memory explicity in my application. Do you have any idea! Today!I checked the running status of the application . I find that there are only 524K memory increasement while sending 570000 messages.Maybe it's a good news.^_^ Don't look at me in that way!
