Android project using Ant

Question

I am using ANT to build android project ,I am adding external jar in the lib folder and trying to build the project it builds perfectly but i am getting run time error ...i have seen some groups they have said that the build.xml has to be modified with these changes

<target name="dex" depends="compile"> 
    <exec executable="${dx}" failonerror="true"> 
        <arg value="-JXmx384M" /> 
        <arg value="--dex" /> 
        <arg value="--output=${basedir}/${intermediate-dex}" /> 
        <arg value="--locals=full" /> 
        <arg value="--positions=lines" /> 
        <arg path="${basedir}/${outdir-classes}" /> 
    </exec> 
</target> 

Add a new arg after the last one:

trouble processing "javax/xml/XMLConstants.class": [2009-05-11 09:24:13 - ChitMeAndroidClient] Attempt to include a core VM class in something other than a core library. It is likely that you have attempted to include the core library from a desktop virtual machine into an application, which will most assuredly not work. If you really intend to build a core library -- which is only appropriate as part of creating a full virtual machine binary, as opposed to compiling an application -- then use the "--core-library" option to suppress this error message. If you go ahead and use "--core-library" but are in fact building an application, then please be aware that your build will still fail at some point; you will simply be denied the pleasure of reading this helpful error message.

this is the compile time error.......
