Why does ANT tell me that JAVA_HOME is wrong when it is not?

Question

I get the error:

C:\\dev\\ws\\springapp\\build.xml:81: Unable to find a javac compiler; com.sun.tools.javac.Main is not on the classpath. Perhaps JAVA_HOME does not

Answer 1

Quick work around for the same is

Copy C:\Program Files\Java\jdk1.6.0_14\lib\tools.jar to C:\Program Files\Java\jre6\lib\

This exception is coming because JAVA_HOME is being set as C:\Program Files\Java\jre6 and Ant is not able to find tools.jar in it.
