Building

To build and deploy the web applications:

Ensure JAVA_HOME environment variable is set and points to a JDK installation (1.4 or later).
Ensure ANT_HOME environment variable is set and points to an Ant installation (1.6.5 or later).
Edit build.properties file and set the dir.appserver property to point to your J2EE web container deployment directory. For example:
```
  # App Server deployment directory
  dir.appserver=C:/java/jakarta-tomcat-5.5.9/webapps 
```
Note on Windows ensure you replace any \ directory path characters with / otherwise Ant may not find the directory.
Run the Ant targets:
```
  ant build-all deploy-webapps 
```
These targets will build the Click framework, extras and example applications, and then copy the WAR files to your Application Servers deployment directory.

The Click framework has the following runtime dependencies.
