Calling Java API via Delphi

[Jaelani C. U.]

Hello,

I was wondering how to use functions from either Microsoft or Sun Java
libraries.
Is it even possible?

Thank you in advance.

You can call functions in native libraries using the JNI - the Java Native
Interface. Documentation on JNI is included in the Sun JDK distribution.

You can call any Java method, including those in the Sun libraries, using
the same mechanisms that you would use to all any Java method. Ensure
that the library is on the classpath and call it. Of course, using
methods that are not part of standard Java can introduce portability
concerns.

Many thanks for that.
I'm gonna find out more about the JNI.
I'll try not to think about portabily issuse, yet.
Thanks for the warning.

These are the only ways that I know of:

(1) EJB calls (must be using Boland's Application Sever)
(2) Corba Bridge (must be using Visibroker) for Delphi.
(3) Web Services
(4) Passing data to/from Delphi to Java Server side sockets through HTTP.
(5) Third party product like ASTA.

I know there are many ways to do it, but I'm trying to exclude any =

internet technology (eg. server, web, socket).
The ASTA you just mentioned. Where can I find out more about it?
Thank you.

For Delphi to Java JNI look on code central. There used to be a JNI for
Delphi on that site, that would allow Java to Delphi communication without
the Network protocols.

Google is your friend... :)

At least it's a good start.
