my Win 2000 machine, it has "c:\Program Files\j2sdk1.4.1_02". Would
anyone know what is my problem?

[javac] BUILD FAILED: file:D:/eclipse/workspace/Jade3/build.xml:66:
Unable to find a javac compiler;
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK

You need to add a jdk tools.jar to the Ant runtime classpath using the Ant
preference pages.
Another option is to start Eclipse using the -vm arg so that Eclipse is
launched using your JDK install VM (your JAVA_HOME). This way Eclipse will
automatically add
the tools.jar to the Ant runtime classpath.

following error:

BUILD FAILED: java.lang.UnsupportedClassVersionError:

The tools.jar you are adding is for a different VM version.
It looks like you are trying to use a 1.4 tools.jar with a 1.3 VM
