Calling Java Swing application in JSP Page

[Sridevi Kumarasamy]

I have an Java Swing application which in turn calls an dll file and three Java files. How can I call this Java Swing application in JSP form, while clicking an button?

I have already converted this Swing application to JApplet(using the same dll and three java files). Is there is any way to call this JApplet in JSP Page?

Hi,

Welcome to JavaRanch!

For a normal applet, the JSP page can simply emit the appropriate "applet" or "embed" tag as part of its normal HTML. This tag should point to the location of the applet on your server. It's not a big deal.

If you really mean DLL, though, as in native code, there are problems. First of all, the Java plug-in won't download your DLL. You're going to have to get your users to install this DLL by some other channel -- i.e., download it and install it themselves. Secondly, for your applet to access the DLL, it's going to need to be digitally signed, and it's going to need to have the right permissions configured.

Finally, there are the cross-platform issues to consider. Only Windows users will be able to use your applet unless you provide versions of your native code for other OSs.
