Trying to use build ...

Help,

Running Red Hat 6.2, Apache Web Server and Jakarta 3.1.

I am trying to compile my java source code using the build shell script using
a build.xml, but I keep getting the following message 

Exception in thread "main" java.lang.NoClassDefFoundError: sun/tools/javac/Main
	at org.apache.tools.ant.taskdefs.Javac.doClassicCompile(Javac.java, Compiled Code)
	at org.apache.tools.ant.taskdefs.Javac.execute(Javac.java, Compiled Code)
	at org.apache.tools.ant.Target.execute(Target.java, Compiled Code)
	at org.apache.tools.ant.Project.runTarget(Project.java, Compiled Code)
	at org.apache.tools.ant.Project.executeTarget(Project.java, Compiled Code)
	at org.apache.tools.ant.Main.runBuild(Main.java, Compiled Code)
	at org.apache.tools.ant.Main.main(Main.java, Compiled Code)

Can anyone help me understand what I have done wrong.

You don't have java's runtime classes in your classpath. Add
$JAVA_HOME/lib/tools.jar to it and everything should be fine.

Try setting $JAVA_HOME to root of java installation (e.g., /usr/java)

Or add <java-home>/lib/tools.jar explicitly to the build classpath
