Ant in Eclipse

[Yonghang Cai]

When i use javac task of ant in eclipse,the error happen.
error is :
[javac] BUILD FAILED: file :/eclipse/workspace/MyEJB/build.xml:26: 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
but I use echo to print JAVA_HOME is
[echo] d:\jdk1.4\jre
<echo message="${java.home}" />
how can i do?I want use javac task in eclipse.
Thank u
PS:My eclipse is 2.1

Hi,
Set JAVA_HOME to d:\jdk1.4\ instead of d:\jdk1.4\jre.
Hope it works.Get back if you have any issues

I can not do it.
If java_home point to jdk folder(use "regedit"),eclipse will not work.
I must copy jre into eclipse folder,but JAVA_HOME be point to jre folder which in eclipse folder.
If I modify JAVA_HOME in environment variable , the JAVA_Home still d:\jdk1.4\jre in ant
How can i do now?
Thanks.

You need to add 'tools.jar' to ANT runtime classpath in eclipse.
