Ant Properties File Tutorial

Lean how to use Ant properties file.

Ant Properties File

You can also group all the property values in a separate properties file and include it in the ant build file. Here the build.properties file contains all the property values. Remember the property value is immutable, so if you set a property value in the properties file you cannot change it in the build file. This give more control over the build process.

Use the property task to include the properties file in the ant build file.

Here is the complete build file for your reference.

You can download the build file here.

The <property> task is used to set properties. The property value is immutable, once the value is set you can not change it. To set a property to a specific value you use Name/value assignment.

Ant Property Task

To set a property to a location you can use Name/location assignment.

To use the properties surround them with ${}.

The following build file shows how to set and use property values.

Ant Sample Build File - WAR

Learn how to create a war file using Ant build file.

Clip Source: www.vaannila.com

I am using the Spring SimpleFormController example to illustrate the build process. The figure below shows the structure of the web application.

All the classes inside the src directory should be compiled and placed in a separate build/classes directory. The created war file will be placed inside the dist directory.

So first we create the build/classes and the dist directory. The init target does this job.

The next step is to compile all the classes in the src directory and place them in the build/classes directory. To do this first you need to add all the lib files inside the "WebContent/WEB-INF/lib" directory to the classpath.

To integrate Ant build file with the Eclipse IDE, first create a build.xml file, right click the project select New->Other->XML, enter the name as build.xml and click Finish.

To build the project right click the build.xml file and select Ant Build.

The HelloWorld.java file will be compiled and executed. The following message shows the sequence of events that happen once the build file is executed.

Ant Sample Build File - JAR

Learn how to create a jar file using Ant build file.

Clip Source: www.vaannila.com

Sample Ant Build File

In this example you will see how to structure the project. If the grows bigger, it will become a problem to manages the files if all the files are there in the same directory.

All the source file should be kept in the src directory, the compressed jar file should be kept in the dist directory and all the intermediate class files should be kept in the build/classes directory.

By imposing structure cleaning the project becomes easy, we can just delete the directory and recreate it.

Using the <mkdir> task we create build/classes and dist directory.

During the compilation process all the java files in the src directory will be compiled and the generated class files will be placed in the build/classes directory.

Ant Installation

Ant is free and open source build tool, written in Java, helps in automating the entire build process of a Java development project.

Ant uses XML build files.

By default, Ant looks for a build file named build.xml.

The build file contains information about how to build a particular project.

Each project contains multiple targets like creating directory, compiling source codes.

Target can depend on other targets.

Targets contain tasks.

Behind each task is a Java class that performs the described work.

To install Ant follow the steps given below.

Download the latest Ant distribution.

Set the following system variables

ANT_HOME =E:\apache-ant-1.7.1

PATH = %ANT_HOME%\bin

Extract it (my location is E:\apache-ant-1.7.1)

You can download the build file here.

Spring MVC Framework Tutorial

In this tutorial you will learn how the Spring MVC Framework works with the help of a simple hello world example.

Clip Source: www.vaannila.com

Spring MVC helps in building flexible and loosely coupled web applications. The Model-view-controller design pattern helps in seperating the business logic, presentation logic and navigation logic. Models are responsible for encapsulating the application data. The Views render response to the user with the help of the model object . Controllers are responsible for receiving the request from the user and calling the back-end services.

When a request is sent to the Spring MVC Framework the following sequence of events happen.
