Java Question

'"java.exe"' is not recognized as an internal or external command,

`JAVA_HOME C:\Program Files\Java\jdk1.7.0_06\bin`
to my windows 7. But when I type the following in the CMD command line on my windows 7
`C:\activiti-5.10\activiti-5.10\setup>ant demo.start`
to run a demo application I got the following error in the command line '

"java.exe"' is not recognized as an internal or external command, operable program or batch file

So does anyone know how i can solve this problem ?

If you look at the "ant.bat" file, you will see that it looks for the "java" command in the following way:

1. If the `%JAVACMD%` environment variable is set, then it uses that.
2. Otherwise, if the `%JAVA_HOME%` environment variable is set, it tries to use `%JAVA_HOME%\bin\java.exe`
3. Otherwise, it tries to use `java.exe`; i.e. it will look on your %PATH%.

In your case, you have `%JAVA_HOME%` set ... but set to the Java installation's "bin" directory, not to the root of the installation. So the `Ant.bat` script looks in the wrong place for `java.exe`.

Just set `%JAVA_HOME%` correctly, and it should work.

``````JAVA_HOME C:\Program Files\Java\jdk1.7.0_06
``````

You don't need to have the Java "bin" directory on your `%PATH%` for Ant to work, but it is a good idea to set it anyway. That way you can run the Java commands simply from the command line.

The setting of `%CLASSPATH%` is not relevant to this problem. Indeed, unless the `build.xml` file is broken, Ant will ignore your `%CLASSPATH%` environment variable.
