hi,
when i use a html-page with this applet-tag:
<APPLET CODE = "applet.MosaicUploader" ARCHIVE = "../applet/
MosaicUploader.jar" WIDTH = 50 HEIGHT = 50>
Here is the MosaicUploader Applet
</APPLET>
the applet is displayed. But if i use the same html in a widget
public class MosaicUploaderAppletWidget
extends Composite
{
public MosaicUploaderAppletWidget()
{
if( GWT.isScript() ) {
initWidget( getAppletHTML() );
}else{
initWidget( new Label( "MosaicUploaderMock for embeded
mode" ) );
}
}
private HTML getAppletHTML()
{
StringBuilder sb = new StringBuilder();
sb.append( "<applet code=\"applet.MosaicUploader\" codebase=\"../
applet/MosaicUploader.jar\" width=50 height=50>" );
sb.append( "Here is the MosaicUploader Applet" );
sb.append( "</applet>" );
return new HTML( sb.toString() );
}
}
the java-console of firefox shows this class not found exception:
Load: class applet.MosaicUploader not found

Using the url http://localhost:8080/MosaicUpload/applet/MosaicUploader.jar
,i can download MosaicUploader.jar which contains a
applet.MosaicUploader.class (in subfolder "applet").
The MosaicUploaderAppletWidget is heavily embeded in Panel-layes. Is
that the problem?
Regards,
Stephan
