<?xml version="1.0" encoding="UTF-8"?>

<project name="MyEJB" basedir=".">

	<property name="src.dir" value="${basedir}/src" />

	<property environment="env" />

	<property name="jboss.home" value="${env.JBOSS_HOME}" />

	<property name="jboss.server.config" value="${jboss.home}/server/default" />

	</target>



	<target name="deploy" depends="ejbjar" description="����Ejb发布Ejb">

	</target>



	<target name="undeploy" description="卸载Ejb">

		<delete file="${jboss.home}/server/${jboss.server.config}/deploy" />

	</target>

</project>

错误是：

Buildfile: E:\作业\MyEJB\build.xml
prepare:
[delete] Deleting directory E:\作业\MyEJB\build
[mkdir] Created dir: E:\作业\MyEJB\build
compile:
[javac] Compiling 4 source files to E:\作业\MyEJB\build

BUILD FAILED
E:\作业\MyEJB\build.xml:23: 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.
It is currently set to "C:\Program Files\MyEclipse 6.5\jre"

请高手指点
