Ant und org.apache.log4j.xml.DOMConfigurator Problem

[qpid]

Ich bekomme wenn ich eine Jar Datei mit einem Parameter mit java ausführe und auswerten möchte folgenden Fehler:

     [code=Java] javax.xml.parsers.FactoryConfigurationError: Provider

Der Eintrag in der build.xml sieht folgendermaßen aus:

        <java classname="packagename.Main" outputproperty="version">

          <classpath>

            <pathelement location="${lib}/TimeFeedback.jar"/>

            <pathelement path="${java.class.path}"/>

          </classpath>

          <arg value="-v"/>

        </java>

Hi,

das Ganze schon mal OHNE Ant probiert?

ja es geht sowohl:

java -cp ./lib/TimeFeedback.jar de.brtech.timefeedback.Main -v

also auch so:

java -jar ./lib/TimeFeedback.jar -v

Mir ist innerhalb des Stacks aber mal aufgefallen, dass dort eine Zeile aus meiner Main als Grund auftaucht.
Und zwar ist das folgende:

DOMConfigurator.configure(Main.class.getResource("log4j.xml"));

Wenn ich diese auskommentiere gehts alles wunderbar, ich habe jetzt erstmal im quellcode die versionsausagbe vor den DOMConfigurator gezogen. Komisch ist das allerdings schon, denn ansonsten bekomme ich damit keine Fehlermeldung oder sonstige Probleme.
