Problem with the classpath embedding ant

[chuchi]

Hi all,

    I'm trying to embed ant into an application but I have a lot of
problems. I have tried to change the classloader, and when I call to
java task all works fine but if I put a taskdef ant cannot find the
class.

Example:

<?xml version="1.0" encoding="ISO-8859-15" ?>
<project name="TestLoaderDemonio" default="defecto" basedir=".">
        <description>
                Prueba cargador de librerias
        </description>

        <taskdef name="mitask" classname="test.TestTask" />
        <target name="defecto" description="Único target que se lanza desde
QDemonio" >
                <java classname="test.TestLoaderDemonio" failonerror="true"
outputproperty="outputproperty"
                         errorproperty="errorproperty">
                <classpath>
           <pathelement path="${java.class.path}"/>
         </classpath>
                </java>
                <echo message="Out: ${outputproperty}"/>
                <echo message="Error: ${errorproperty}"/>
                <mitask mensaje="Lanzamos mi task" />
        </target>
</project>

If I execute ant in the command line all  works fine:

ant -f buildLoader.xml
-lib /home/chuchi/wd/QDemonioTareas/src/test/resources -debug

But if I execute the Launcher from a java class, It does not work:

public static void main(String[] args) {
     String args2[] = {
          "-f",

TestLoaderExtDemonio.class.getResource("/buildLoader.xml").getPath(),
          "-lib",
          "/home/chuchi/wd/QDemonioTareas/src/test/resources",
          "-debug"
     };
     Launcher.main(args2);
}

The error is a ClassNotFoundException (test.TestTask)

Can you help me? I have been reading two days in FAQ, List, Google...
But I cannot see any solution

Regards,
    Chuchi

Hi again,

    If I comment the <taskdef...> and the <mitask...> works fine. As you
can see, the java task load the libraries correctly but the taskdef task
not

Hello,

Is it possible to do a substring operation with Ant?

Cheers,
Anthony

Not exactly.

But it is possible to do a string/token replacement -- not exactly
what you asked, but it can get the job done. This is done using a
FilterChain, http://ant.apache.org/manual/CoreTypes/filterchain.html

I'm using this feature to replace certain strings in my files with the
empty string (removal). In the example below, I replace "from" with
"to"
from: "APE.namespace("APE.dom");"
to:    ""


http://dhtmlkitchen.com/ape/build.xml
<concat destfile="${src}/dom/_dom.js">
<filelist dir="${src}/dom" files="viewport-f.js, position-f.js,
classname-f.js, traversal-f.js, Event.js"/>
  <filterchain>
    <tokenfilter>
      <replacestring from="APE.namespace("APE.dom");" to=""/>
      <replacestring from="APE.namespace('APE.dom');" to=""/>
    </tokenfilter>
  </filterchain>
</concat>

Hello Anthony,

the StringUtils task from antelope should help you.

Yes, but not with standard ANT. You have to use the stringutils plugin from antelope with docs here:  http://antelope.tigris.org/nonav/docs/manual/bk03ch13.html
