ActiveMQ Message Producer. This is the java client program for sending messages to Queues. JMS supports 5 different types of messages, namely TextMessages, MapMessages, BytesMessages, StreamMessages and ObjectMessages. C - Memory Management - This chapter explains dynamic memory management in C. The C programming language provides several functions for memory allocation and management.

C programming is a general-purpose, procedural, imperative computer programming language developed in 1972 by Dennis M. Ritchie at the Bell Telephone Laboratories to develop the UNIX operating system. C is the most widely used computer language. It keeps fluctuating at number one scale of popularity along with Java programming language, which is also equally popular and most widely used among modern software programmers.
C programming language is a MUST for students and working professionals to become a great Software Engineer specially when they are working in Software Development Domain. I will list down some of the key advantages of learning C Programming:
Easy to learn
Structured language
It produces efficient programs Verd still love you mp3 downloader.
It can handle low-level activities
It can be compiled on a variety of computer platforms
C was invented to write an operating system called UNIX.
C is a successor of B language which was introduced around the early 1970s.
The language was formalized in 1988 by the American National Standard Institute (ANSI).
The UNIX OS was totally written in C.
Today C is the most widely used and popular System Programming Language.
Most of the state-of-the-art software have been implemented using C.
Just to give you a little excitement about C programming, I'm going to give you a small conventional C Programming Hello World program, You can try it using Demo link.
C was initially used for system development work, particularly the programs that make-up the operating system. C was adopted as a system development language because it produces code that runs nearly as fast as the code written in assembly language. Some examples of the use of C are -

This tutorial is designed for software programmers with a need to understand the C programming language starting from scratch. This C tutorial will give you enough understanding on C programming language from where you can take yourself to higher level of expertise.
Before proceeding with this tutorial, you should have a basic understanding of Computer Programming terminologies. A basic understanding of any of the programming languages will help you in understanding the C programming concepts and move fast on the learning track.
In this tutorial, we will learn how to send different types of messages to ActiveMQ queues.
Example Scenario:
We need to read java String and different types of files and convert them to JMS messages and send to ActiveMQ queues to be received by some other application.
Project artifacts:
1. Technologies used –
a. Eclipse IDE for Java EE developer 4.5.0.20150621-1200 (Mars)
b. Preinstalled Maven with Eclipse Mars
c. Java 1.8
d. ActiveMQ 5.13.0
Jars used –
In case you are not using maven, please find below the list of jars used in this java application:
activemq-client-5.13.0.jar
slf4j-api-1.7.13.jar
geronimo-jms_1.1_spec-1.1.1.jar
hawtbuf-1.11.jar
geronimo-j2ee-management_1.1_spec-1.0.1.jar
2. Eclipse project folder structure:
3. A simple Maven Project
Create a simple maven project skipping archetypes.
4. Maven Dependencies
file: pom.xml. Maven unit of work to declare project dependencies, compile code and call main method of java JMS client. It has Active MQ client dependency and plugin to execute our class.
5. POJO
file: MyMessage.java. A SerializablePOJO class whose objects will be sent to Queues.
C# Activemq Example Definition
6. ActiveMQ Message Producer
file:QueueMessageSender.java. This is the java client program for sending messages to Queues. JMS supports 5 different types of messages, namely TextMessages, MapMessages, BytesMessages, StreamMessages and ObjectMessages. The below client depicts all of the messages in action in a client role.
- createAndSendTextMessage : Text messages are the simplest of the JMS messages which takes string as a body of the message. This method creates 100 text messages and sets integer, float and String property of the message before sending it to ActiveMQ.
- createAndSendObjectMessage : Object message takes any java serializable object as message body. This method creates 100 object messages of type MyMessage and sets integer property of the message. Please note that the class MyMessage is serializable.
- createAndSendMapMessage : Map messages consist of key value pairs where key is generally String while value can be any of the java primitive types. This method creates 100 map messages of different types which includes float, String, Integer and Double. You can even set Byte, Long, Char, Boolean and Object values in Map message.
- createAndSendStreamMessage : A stream message is a stream of java primitives that should be read sequentially. In this method, a stream message is created and a file is read and written to Stream message as bytes.
- createAndSendBytesMessage : Bytes messages are used to read a stream of uninterpreted bytes. Two different file types, namely pdf and jpg are read in this method and sent to ActiveMQ as messages.
C++ Codes Examples
Example Execution:
Activemq Getting Started
- Start ActiveMQ and run the client program by executing 'maven clean and install'.
- Once it finishes, open your favorite browser and type 'http://localhost:8161/admin'
- Provide username as 'admin' and password as 'admin', if asked for.
- Click on Queue Tab and you should see a Queue named 'FirstQueue' created with 303 messages in it. Click on 'FirstQueue' queue and you will see all the different types of messages with their JMS message ids and types.
