Java Web Application Development With Click Framework/Building

Click uses an Ant based build system for creating JAR files, application WAR files and the Click distribution.

• Build Configuration
• Ant Targets
• Framework Dependencies
• Extras Dependencies

Build Configuration

The configuration of the Click Ant build system is detailed below:

 --[build] Ant build directory | | | ---build.xml Ant build script | | | ---build.properties Ant build properties | --[dist] JAR and WAR file output directory | --[documentation] Click documentation set application | --[examples] Click Examples application | | | ---build.xml Ant build script | | | ---README.txt Click Examples Readme file | --[extras] Click Extras source directory | --[framework] Click framework source directory | --[lib] Dependent JAR libraries directory | --[mock] Mock objects source directory 

Build Requirements

Ensure the following requirements are met before performing builds:

1. Ensure JAVA_HOME environment variable is set and points to a JDK installation (1.4 or later).
2. Ensure ANT_HOME environment variable is set and points to an Ant installation (1.7.0 or later).
3. Ensure junit.jar is present in your ANT_HOME/lib directory.

Ant Targets

ant help Buildfile: build.xml help: [echo] Click web application framework [echo] =============================== [echo] Main targets: [echo] build-all build framework, extras, examples [echo] build-distribution build distribution ZIP file [echo] build-examples build click-examples WAR file [echo] build-extras build click-extras JAR file [echo] build-framework build click framework JAR file [echo] build-maven-bundles build Maven repository upload bundles [echo] build-sources build source ZIP files for use with IDEs [echo] deploy-examples copy examples WAR files to app server [echo] get-deps download JAR dependencies [echo] get-deps-proxy download JAR dependencies via proxy [echo] help display the Help message [echo] javadoc create Javadoc HTML files [echo] Please ensure you have configured build.properties BUILD SUCCESSFUL 

Getting Dependencies

Run the Ant target get-deps to download JAR dependencies from Ibiblio Maven repository:

ant get-deps

If you are behind a firewall use the Ant target get-deps-proxy and configure your proxy settings in build.properties

# Proxy hostname used by Ant target 'get-deps-proxy'proxy.host=192.168.0.3# Proxy port for by Ant target 'get-deps-proxy'proxy.port=3128

Building Framework

To build the Click framework JAR file click.jar

1. Ensure the above configurations have been made and get-deps has been run.
2. Run the Ant target build-framework to build the framework:

ant build-framework

Building Extras

Click Extras JAR file click-extras.jar

1. Ensure the above configurations have been made and get-deps has been run.
2. Run the Ant targets framework and build-extras:

ant build-framework build-extras

Building Examples

To build the Click Examples and Click QuickStart web application WAR files:

1. Please see the examples/README.txt file, ensuring the required properties have been configured and the dependencies downloaded.
2. Ensure the above configurations have been made and get-deps has been run.
3. Run the Ant target build-all:

ant build-all

Framework Dependencies

The Click framework has the following runtime dependencies.
