Java EE (Java Enterprise Edition) General Discussion

Hello all,
I am trying to work on Bookstore example and i don't have a clue whats happening. My asant build works but Shows nothing but....
C:\j2eetutorial14\examples\web\bookstore>asant build
Buildfile: build.xml

and then i have to termintae the batch job becos it takes forever to go further. I feel there is something wrong with my ANT_HOME settings. can somebody help me with what exactly should be set and in which location ? My other environment variables are set as following :

My J2EE_HOME environment variable is set to C:\sun\appserver\lib\j2ee.jar,
JAVA_HOME is set to c:\sun\appserver.
PATH=c:\Sun\appserver\jdk\bin;c:\sun\appserver\bin
classpath=c:\program files\apache group\tomcat4.1\common\lib\servlet.jar

Any help would be greatly appreciated.
Thanks.
