J-Interop: Open Source DCOM Access without JNI

By vikramrc ·
For anyone interested:

j-Interop(http://j-interop.sourceforge.net) implements DCOM wire protocol (MSRPC) to enable development of Pure Bi-Directional, Non-Native, Java applications which can interoperate with any COM component.The implementation itself is purely in Java and does not use JNI to provide native access,thus being truly platform independent. It has full support for COM automation and supports callback from COM Servers (event handling).

1.01(a) has been tested on Windows XP/2K/2K3 and Fedora 5. Beta is expected out by first week of september.

This release can be downloaded from http://sourceforge.net/project/showfiles.php?group_id=174727

However if you have the choice

would'nt it be better to write your remote object as a CORBA (I know I'm going to get blasted for this) object. That way you can use RMI IIOP and this is fairly easy and included with J2SE (starting with 1.3 or 1.4 I think).
Our experience with DCOM is not very good (the thing has really not been very reliable). CORBA is much more mature and platform independent with a much wider choice of implementation and options.
Although it is nice to know about j-interop (thank you for that) the only reason I see to use DCOM would be to use an existing component. For a new component I would go with CORBA (despite the learning curve).

Yes, if you would have a choice , you could do it that way. But the purpose of j-Interop is to bridge a technical divide. It would be used when you have a COM server and want Java integrated with it.

best regards,
Vikram
