  • Could not create task or type of type: antlib:org.apache.catalina.ant.jmx:open.

    Hi There,

    I was trying this jmx graph for more than 2 weeks and i'm a newbie to tomcat and ant,maven. All i was trying to get the graph for jmx from the percona they say before test the script you should try this and the error is something like this.

    ant -Djmx.server.port=8080 -e -q -f jmx-monitor.xml

    BUILD FAILED
    /root/jmx-monitor.xml:29: Could not create task or type of type: antlibrg.apache.catalina.ant.jmxpen.

    Ant could not find the task or a class this task relies upon.

    This is common and has a number of causes; the usual
    solutions are to read the manual pages then download and
    install needed JAR files, or fix the build file:
    - You have misspelt 'antlibrg.apache.catalina.ant.jmxpen'.
    Fix: check your spelling.
    - The task needs an external JAR file to execute
    and this is not found at the right place in the classpath.
    Fix: check the documentation for dependencies.
    Fix: declare the task.
    - The task is an Ant optional task and the JAR file and/or libraries
    implementing the functionality were not found at the time you
    yourself built your installation of Ant from the Ant sources.
    Fix: Look in the ANT_HOME/lib for the 'ant-' JAR corresponding to the
    task and make sure it contains more than merely a META-INF/MANIFEST.MF.
    If all it contains is the manifest, then rebuild Ant with the needed
    libraries present in ${ant.home}/lib/optional/ , or alternatively,
    download a pre-built release version from apache.org
    - The build file was written for a later version of Ant
    Fix: upgrade to at least the latest release version of Ant
    - The task is not an Ant core or optional task
    and needs to be declared using .
    - You are attempting to use a task defined using
    or but have spelt wrong or not
    defined it at the point of use

    Remember that for JAR files to be visible to Ant tasks implemented
    in ANT_HOME/lib, the files must be in the same directory or on the
    classpath

    Please neither file bug reports on this problem, nor email the
    Ant mailing lists, until all of these causes have been explored,
    as this is not an Ant bug.

    Total time: 0 seconds

    And i put .jar package into ANT_HOME:
    ll .ant/lib/
    total 84
    -rw-r--r-- 1 root root 53756 Mar 18 08:22 catalina-ant.jar
    -rw-r--r-- 1 root root 24178 Mar 18 08:23 catalina-ant-jmx.jar

    echo $ANT_HOME
    /root/.ant/lib/

    How should i candle this.

    Please help me!

    Thanks,
    P
