Put build.xml in a directory, then create the following directory tree:
/
- /src/
- - /com/
- - - /cfdev/
- - - - /hello/
- - - - - HelloWorld.java
- /include/
- - anyjarToAddToClassPath.jar
- build.xml
then run the ant task, after installing Jakarta Ant.
> ant
this will run the default task called "run" which invokes the dependent tasks jar, compile, and init
if you just want to compile the classes run
> ant compile
if you want java docs:
> ant docs
build.xml:
<?xml version='1.0'?>
