Hi,

I have an application using synth thar works right. But now, if I call the main method by reflection I obtain this exception and synth isn't loaded:

java.text.ParseException: Error parsing: org.xml.sax.SAXException: ID tabbedPanePainter has not been defined null

at com.ya.services.photoprinting2.updater.application.Updater.main(Updater.java:73)

The application is in jar JPhotoPrinting.jar, and to call main method I do:

StringBuffer sbPhotoPrintingJarPath = new StringBuffer(64).append("file:///").append(sLibDirectory).append("/JPhotoPrinting.jar");
StringBuffer sbSwingWorkerJarPath = new StringBuffer(64).append("file:///").append(sLibDirectory).append("/swing-worker.jar");
URL[] jarUrls = {new URL(sbPhotoPrintingJarPath.toString()),
new URL(sbSwingWorkerJarPath.toString())};
URLClassLoader myclassLoader = new URLClassLoader(jarUrls);
Class theClass = myclassLoader.loadClass("com.ya.services.photoprinting2.gui.component.JFrameApp");

Method mainMethod = theClass.getMethod("main", new Class[]{String[].class});
mainMethod.invoke(null, new Object[] {new String[] {Integer.toString(iEnv)}});

At the main method of JFrameApp I do:

SynthLookAndFeel synth = new SynthLookAndFeel();
synth.load(JFrameApp.class.getResourceAsStream("/resources/data/synth.xml"), JFrameApp.class);
UIManager.setLookAndFeel(synth);

�Which is the problem?

Thanks
