Question

I am trying to start/stop tomcat from Ant. Here is my relevant portion of the xml file for stopping :

<target name="stop" depends="readProperties" >
    <exec executable="/home/local/WorkEnvironment/apache-tomcat-7.0.14/bin/">
        <arg value="shutdown.sh"/>
    </exec>
</target>

This gives the following exception :

/home/local/workspace/Eclipse/Main/tomcat.xml:26: Execute failed: java.io.IOException: java.io.IOException: Permission denied

   at java.lang.PosixProcess$ProcessManager.run(libgcj.so.11)

Seeing this, I tried the following :

<target name="stop" depends="readProperties" >
    <echo message="${tomcat.path.home}"/>

    <java jar="${tomcat.path.home}/bin/bootstrap.jar" fork="true">
           <jvmarg value="-Dcatalina.home=${tomcat.path.home}"/>

            <arg line="stop"></arg>
    </java>
</target>

This tells me that :

stop:
     [echo] /home/local/WorkEnvironment/apache-tomcat-7.0.14
     [java] Exception in thread "main" java.lang.NoClassDefFoundError: org.apache.juli.logging.LogFactory

     [java]    at java.lang.Class.initializeClass(libgcj.so.11)
     [java] Java Result: 1

I checked for tomcat-juli.jar and its present in tomcat_home/bin and also in tomcat_home/lib. It also has the class which ant says is missing. What is going wrong ? I saw that sometimes the Manifest.MF file can mislead, but, I could not make out what exactly could be wrong with that file 🙁 .

Answer 1

Shouldn’t executable include “shutdown.sh”? (not shutdown as an arg, but as part of the executable path).

Something like:

<target name="stop" depends="readProperties" >
    <exec executable="/home/local/WorkEnvironment/apache-tomcat-7.0.14/bin/shutdown.sh">
    </exec>
</target>
