Web Application for JDBC access

Web applications

This application uses JMS API for your business logic and Java Servlet API for user interface. As we go through the tutorial we will try to understand the basic of Servlets and JMS.

To run this tutorial, as a minimum you will be required to have installed the following prerequisite software.

• Sun JDK 5.0+ (J2SE 1.5)
• Eclipse 3.3.1.1 (Eclipse Classic package of Europa distribution), which is platform specific
• Web Tools Platform (WTP) 2.0.1
• Data Tools Platform (DTP) 1.5.1
• Eclipse Modeling Framework (EMF) 2.3.1
• Graphical Editing Framework (GEF) 3.3.1

Details on installing eclipse are provided in the Development environment section. This tutorial is organized in the following sections:

The application development will take you through the following

Creating a Dynamic Web Project

1. Launch Eclipse. Select File->New->Project.
   
   
   
   
   
   
2. Select Web->Dynamic Web Project. Select Next.
   
   
   
   
   
   
3. On the next screen give the name of the project as WebJMS.
   
   
   
   
   
   
4. Select default values for all other fields. Finally select Finish.
   
   
   
   
   
   

Creating Connection Factory and Destination

In simple terms a Connection Factory is an object which is used by a client to connect to the Service provider. In our case we will be using Active MQ as the provider.
Destination is an object which is used by client to provide the target to messages produced and source of the messages to be consumed. In our case the target is going to be a queue.

Let us see how we can use the administrative console to create a Connection Factory and Message Destination.

1. Start the server and Launch the administrative console.
2. Under Services. Select JMS Resources.
   
   
   
   
   
   
3. Under Create a new JMS Resource Group:. Select For ActiveMQ.
   
   
   
   
   
   
4. On the next screen suggest a Resource Group Name. In our case we are using WebJMS. All other values can be taken as default.
   
   
   
   
   
   
5. Select Next once done.
   
   
   
   
   
   
6. Select Add Connection Factory on the next page.
   
   
   
   
   
   
7. In the drop down box select javax.jms.QueueConnectionFactory. Select Next.
   
   
   
   
   
   
8. Next give the Connection Factory Name as jms/TestConnectionFactory. Keep default for all other fields. Select Next.
   
   
   
   
   
   
9. Select Add Destination on the next screen.
   
   
   
   
   
   
10. Select JMS Destination Type as javax.jms.Queue. Select Next.
    
    
    
    
    
    
11. Name the Message Destination Name as jms/TestQueue. Select Next.
    
    
    
    
    
    
12. On the next screen Select Deploy Now. This will deploy the created Plan.
    
    
    
    
    
    
13. Under JMS resources you can see the newly created connection factory and queue.
