    Looks like you build file cannot find the task class. You should check to make sure the jar the build file is looking for is present in the directory specified in the build file.

    my tomcat base folder is located at c:\tomcat6

    There are 17 jar files in the c:\tomcat6\lib folder:
    annotations-api.jar, catalina-ant.jar, …., etc.

    I suspect I did NOT set up the tomcat server within the MyEclipse environment correctly.

    Could you provide me with a detailed procedure how to set up the tomcat6 folder in the MyEclipse environment?

    Thanks,
    Jimmy

    I copied the catalina-ant.jar file from the tomcat6 lib folder to the ant lib folder.
    It is working now.

    New Question:

    How do I set the tomcat manager username and password in MyEclipse?

    I’ve already set the manager role correctly in the tomcat-users.xml file.

    Thanks,
    Jimmy

    <target name=”install” description=”Install application in Tomcat”>
    <install url=”${tomcat.manager.url}”
    username=”${tomcat.manager.username}”
    password=”${tomcat.manager.password}”
    path=”/${name}”
    war=”${name}” />
    </target>

    The tomcat administrator has been discussed in this post. Hope that helps:-

    Perhaps I did NOT explain my problem clearly.

    The tomcat manager is set up CORRECTLY, I can access it from
    http://localhost:8080 with NO problem.

    The PROBLEM that I HAVE is listed below

    Buildfile: C:\workspace\simplepro1\build.xml
    install:

    BUILD FAILED
    C:\workspace\simplepro1\build.xml:113: java.net.MalformedURLException: no protocol: ${tomcat.manager.url}/install?path=%2Fsimplepro&war=simplepro

    1. For all the taskdefs it would be easier to set an “id” attribute on the first <taskdef><classpath> and use <taskdef><classpath refid> for following taskdefs.
    2. When you add JARs to ANT_HOME/lib you change the Ant classpath for other projects too. So be careful with that.
    3. Is you property appserver.home set correctly? Ensure that ${appserver.home}/lib/catalina-ant.jar is found.
    4. Your last problem seems to be that the property tomcat.manager.url is not set. Otherwise the error message would print the calculated value.
