Java Applets - Interacting

Wayne Gibson

12/17/2002 2:31:00 PM

Hi,
Was wondering if anybody could help me with the following problem..

I have written a java applet to display some of my 3D Models. I choose to
write it in JAVA to avoid the 20MB download for the CLR, also so that it
would run on other platforms.

But I would like to use the .NET framework (C#) to do all the interface work
and database connections.

Was wondering if anybody has seen or has an example code for communication
with a Java applet, either implement in the .NET code or on a seperate
frame.

Thanks

Well, I'm sure you could hack up some way to make it work, but its been
my experience that Microsoft and Java don't play well together. I
always end up with headaches when I have to integrate microsoft stuff
with other systems... or for that matter, same headaches integrating
java based environments with MS... it all depends on the perspective.

Unless you really have some compelling reason, I would go all java or
all microsoft. either one will work.

Not sure about C# and Java communication. Certainly direct communciation
would be rather difficult, but intermediate approaches (process linkage, temp
files etc..) are always possible.

I have had great success using Java and COM and win32 api (of course, it DOES
require the ubiquitous MS JVM). The advantage is that you are pretty sure almost
all of your win32 clients (excepting some XP systems) will have that JVM
readily available.

Why not creating a WebService with the functionallity and call it from the
Applet?

Hi Wayne,

Did you want this applet to remain in the browser (without posting back)
while having two-way communication with the server?
If you use .NET on the server, there are two options: remoting and web
services.
You cannot use the Java RMI (Java Remote Method Invocation) because it is
not available on Windows.

Below is information on remoting and web services. I suspect you will be
more interested in web services. For this, your applet will need to send
and receive HTTP requests/responses.

I do not have any Java applet sample code.
