So ANT_HOME varies widely by individual, OS, software version etc, while the contents of ANT_HOME for *anyone* should be pretty much the same (given same or similar versions). Modify your PATH environment variable to account for the location of executables (like programs in a "bin" directory); otherwise, construct paths to the executables as required using the *_HOME variables (e.g. "%ANT_HOME%\bin").

Well this is what I've been doing. I get java but not javac or jar. So I know I'm doing something wrong I wrote a small batch file I call j.bat. Here's a copy: @echo off set path=c:\program files\java\jdk1.8.0_20\bin;%path% set classpath=c:\program files\java\jdk1.8.0_20\lib\tools.jar;%classpath% I get java but not javac or jar. Not to mention ant. Bill

JAVA_HOME should point to the root. But it is the bin dir that needs to be in PATH. Arne

Not to mention ant. You can drop the CLASSPATH completely. If you do: set path=c:\program files\java\jdk1.8.0_20\bin;%path% and: c:\program files\java\jdk1.8.0_20\bin\javac.exe c:\program files\java\jdk1.8.0_20\bin\jar.exe exists, then the javac and jar commands should exist. But somehow I doubt that those files exist. We are waiting for Java 1.7 - Java 1.8 is way out in the future. Arne
