Actually it doesn't run well.... : I don't know where to place the .jar and .class files neither how to define the bindings...
I need to get an HTML output like :
<APPLET archive=ptviewr.jar code=ptviewer.class width=320 height=200>
<PARAM name=file value=".... a dynamic file path"
</APPLET>
this WOApplet is defined in a ResultPage (resulting from a long request image conversion)
I defined the .wod like that
PtviewerAppplet: WOApplet {
code = "ptviewer.class";
file = convertedFilePath;
height = 200;
width = 300;
archiveNames = ptviewer.jar;
}
When I run the app, I got an error (I believe when loading the WOApplet component...)

Thanks Colin, the basic usage seems pretty simple... I strated from WOApplet definition....
As a 'perfectionist' i like to understand the big picture, so I am also searching example about using the association class to transfer parameters...
that's why I ended lost into so many information searching Google... including things about WebStart (? from Sun) or EOApplet...

Hi Erwin,
I have seen a WOApplet component in the WO Doc , but no example on how to use it..
why.... is it so simple ? or it's never used ?
what's the difference with EOApplet ? (also available in the API )
WOApplet looks pretty simple to me. It's summarized in the WebObjects Dynamic Element reference documentation. Just bind up the parameters you need for your applet--for example, height, width, class name, jar file--and you're done.
If you want to do more complicated things such as messaging between the applet and your WO app, obviously there will be more involved. But it sounds like you just want to embed a simple Java applet in your application. You'd do this using the WOApplet dynamic element or the static HTML tags just like you would for any other site, WebOjects or not.
I check this list archive... nothing about it recently (5.2 /5.3) many information on NeXT/WO
is it deprecated ?
No, it's not deprecated and is still in WebObjects 5.2.3, the latest version.
