Extend class from loaded DLL

[john tindell]

How do i extend a class from one that i want to load from a DLL?

So far i know this. To load the DLL i use

System.loadLibrary("ShellBasics");

The class that i want to use is

ShellLib.ApplicationDesktopToolbar

I have looked around and found something about a classloader, but i wasn't to sure if this was only for use with compiled java classes or not? Any help would be great.

Thanks

What kind of DLL is that?

Does it matter?
it's not Java dll anyway!

[CornedBee]

Yes, it does matter. Is it an ActiveX DLL accessed via the bridge? Is it a JNI DLL implementing a few functions? Or is it a .Net DLL the OP mistakenly believes he can access?

[ComputerJy]

Can you do it from anyone of those types?
I mean extend a class

I'm very curious about that, cause it'd make my life easier

[john tindell]

It is a .NET DLL, although i have the source code to it i can implement it though java would rather just use the DLL because im lazy.

It's not possible to use .Net classes in Java. The bytecode is different, the virtual machines are different.

I thought that's what interoperability is for!

[CornedBee]

Which interoperability? J# is a compiler that attempts to compile Java to .Net bytecode, but it's not Java, and it doesn't have large parts of the Java standard library, so most complex applications probably won't compile.
.Net and ActiveX - interoperatibility doesn't go any further than that. The Java-ActiveX bridge is a kludge at best. There is, I believe, a project somewhere that attempts to combine a Java and .Net virtual machine into one program so that you can mix their bytecodes, but I have no idea about its progress, or if the idea is even feasible.
