I guess mysql related jar file is missing in your Java folder... put it under JAVA_HOME/jre/ext

it may work..

I set JAVA_HOME like u said but it still error.below is the error msg while I compile

C:\>cd Tomcat4-1\webapps\jrts\

C:\Tomcat4-1\webapps\jrts>ant -buildfile build.xml

Warning: JAVA_HOME environment variable is not set.
If build fails because sun.* classes could not be found
you will need to set the JAVA_HOME environment variable
to the installation directory of java.
