ant - build failed

843834Dec 22 2003 — edited Aug 17 2004

Hi guys, I was using ant to build my servlet project but in vain. My build.xml contains the following taskdefs.

  <taskdef name="deploy" classname="org.apache.catalina.ant.DeployTask" /> 
  <taskdef name="list" classname="org.apache.catalina.ant.ListTask" /> 
  <taskdef name="reload" classname="org.apache.catalina.ant.ReloadTask" /> 
  <taskdef name="undeploy" classname="org.apache.catalina.ant.UndeployTask" />

I've copied the catalina-ant.jar to the $ANT_HOME/lib folder as instructed. I could actually run ant on the same build.xml file yesterday, but not today unfortunately. Here is the error message:

build.xml:146: taskdef A class needed by class org.apache.catalina.ant.DeployTask cannot be found: o
