Hi Stephan
The codebase parameter you construct in the getAppletHTML() method
does not look right. You create this codebase='../applet/
MosaicUploader.jar' instead of codebase='../applet/'
archive='MosaicUploader.jar' .
For an even easier applet integration check out the GwtAI project:
http://code.google.com/p/gwtai/

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:

Using the urlhttp://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?

Stephan
