Hi, there's a small error in the build.bat example preventing ant from running unless it is already present in the user's CLASSPATH both the html page and the example file are affected: http://jakarta.apache.org/tomcat/tomcat-4.0-doc/appdev/source.html#Scripts http://jakarta.apache.org/tomcat/tomcat-4.0-doc/appdev/sample/ <code> rem Identify the custom class path components we need set CP=%TOMCAT_HOME%\lib\ant.jar;%TOMCAT_HOME%\lib\servlet.jar set CP=%TOMCAT_HOME%\lib\jaxp.jar;%TOMCAT_HOME%\lib\parser.jar set CP=%CP%;%JAVA_HOME%\lib\tools.jar <code> the third line should read: set CP=%CP%;%TOMCAT_HOME%\lib\jaxp.jar;%TOMCAT_HOME%\lib\parser.jar instead of set CP=%TOMCAT_HOME%\lib\jaxp.jar;%TOMCAT_HOME%\lib\parser.jar I'm also taking this opportunity to thank everyone involved in the project for the outstanding work so far, cheers, nicolas b.
