i'v set the java_home

D:\hibernate-2.1>set java_home
JAVA_HOME=D:\jdk1.4.1_05

Check if you can call a simple <javac> task without Hibernate.

Thank you,everybody!

i found when i delete %JAVA_HOME%\jre\lib\ext\*.jar ,excluding the orginal jdk .jar. and put the file hibernate2.jar to the %Hibernate_Home%\lib,the problem is fixed!!!

suprising?!
