Problem using script task

[Jason Rosenberg]

Hello,   For some reason, I am having trouble using the script task.  I am using Ant 1.2. I apparently do have the correct defaults.properties file, which references the script task as being in the optional.jar, and the optional.jar I have does include Script.class, and optional.jar is in my classpath, since I am able to run other tasks contained in it, such as ejbjar.....   Any ideas?   I am using JDK 1.3.   It happens both on Windows NT 4.0 and on Solaris 7.   Below is the script file I am trying to run, taken from one of the examples in the online doc for the script task:   *********************************************************   <project name="squares" default="main" basedir=".">     <target name="setup">       <property resource="defaults.properties"/>     <echo message="the value of 'script' = '${script}'"/>       <script language="_javascript_"> <![CDATA[         for (i=1; i<=10; i++) {         echo = squares.createTask("echo");         main.addTask(echo);         echo.setMessage(i*i);       }       ]]> </script>     </target>     <target name="main" depends="setup" />   </project>   **********************************************************   Below is the output when I try to run with it:   **********************************************************     D:\NewWork\SourceRoot>ant -buildfile text2.xml Buildfile: text2.xml   setup: the value of 'script' = 'org.apache.tools.ant.taskdefs.optional.Script'   BUILD FAILED   D:\NewWork\SourceRoot\text2.xml:8: Could not create task of type: script because I can't find it in the list of task class definitions.  Com mon solutions are: 1 execute bin/bootstrap. 2 use taskdef to declare your task. 3 add the task to defaults.properties.   Total time: 1 second D:\NewWork\SourceRoot>   ********************************************************
