Experienced members,

Can someone point me in the direction of utilizing some existing objects
that where writing in java. I was given a .jar file with some documentation
about the classes within it.

I am trying to create a instance of these classes from within vb.net (VS
2003 Framework 1.1). Can someone point me in the direction I need to go or
some good documentation?

Thanks,

Chris Smith

You cannot use Java classes in .NET directly.

Hi Chris --

The link you supply below requires the MS JVM, and the days of the MS JVM
are numbered. Also, the MS JVM doesn't support the most up-to-date Java (it
only supports up through JDK 1.1.4 and a few other classes), and may not run
your jar file.

You have a couple of choices in doing interop. One is to use one of the
interop technologies that Herfried mentions below. I, of course, recommend
JNBridge. :-) BTW, the link http://www.jnbridge.com/1dot2beta.htm that
Herfried supplied is out of date -- simply use www.jnbridge.com.

The other choice is to use the jbimp.exe tool supplied with the .NET SDK.
This will convert Java binaries and jar files to MSIL, but only if the
binaries only depend on JDK 1.1.4 and JDK 1.2 collections, so you may not be
able to use it.

I will agree that you just can use java natively, but this I think is pretty
close. You think this will work in .NET languages?
