Question

I am getting some problem while running ant
Here is the details of problem:

C:\jboss-5.1.0.GA\server\default\deploy\mdd_install\mc_config\ant\compile\compile.xml:30: 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
    at org.apache.tools.ant.taskdefs.compilers.CompilerAdapterFactory.getCompiler(CompilerAdapterFactory.java:105)
    at org.apache.tools.ant.taskdefs.Javac.compile(Javac.java:924)

    at org.apache.tools.ant.Project.executeSortedTargets(Project.java:1216)
    at org.apache.tools.ant.Project.executeTarget(Project.java:1185)

I echo java_home and its value is correct
I am running my aplication from jboss and try to execute it, but it is getting the above exception. I put tools.jar in jboss server lib folder ,with that it is runnig fine,but it is not correct way.

Make sure the case of the path to JAVA_HOME is right. Reopen the window or environment you’re running ant from to make sure it’s using the updated environment vars.
