2000 August - Oracle Application Server and Oracle8i
You would assume two complementing products of the same supplier, released during the same period, to be installation compatible. However, when installing the Oracle Application Server (I tried it in version 4.0.8.1) next to Oracle 8i (v 8.1.5), a number of problems can occur.
Read Dave's findings (including some Java tips) and save yourself some valuable time...

VisiBroker 4 for Java
Inprise announced VisiBroker for Java 4.0, the Linux version of its CORBA ORB.
VisiBroker for Java and VisiBroker for C++ are technology leaders in implementing the latest OMG CORBA specifications. Continuing this leadership, VisiBroker 4 now provides full support for CORBA 2.3, including:

Hubert A. Klein Ikkink (aka Mr.Haki) has written an article about the installation of VisiBroker 4 on Linux.

VisiBroker 4 for C++Builder 5
C++Builder 5 Enterprise comes with VisiBroker 4 for your CORBA work. Unfortunately, I found out (the hard way!) that VisiBroker 4 is not backwards compatible with VisiBroker 3.3 - it breaks your existing CORBA servers and clients (especially when written in Delphi 5, which relies on VisiBroker 3.3).
This may not be an issue for you, but I had to re-install VisiBroker 3.3 and VisiBroker for Delphi 5 again to get things back to work again...

VisiBroker 3.3 for Delphi 5
VisiBroker for Delphi has been made available for free download. This tool implements the OMG CORBA specs for Delphi developers, and contains an IDL2PAS, among others.
The Delphi Magazine #54 contains a detailed article about this addition to Delphi 5 Enterprise!

CORBA Book Reviews (six titles)

CORBA stands for Common Object Request Broker Architecture, and is an object-oriented communication architecture between a client and a server. Communication is handled by the ORB (Object Request Broker) and IIOP (Internet InterORB Protocol). Using IDL (Interface Definition Language) we can specify objects with methods and properties. Methods are like functions that can be called by the client, and will be implemented (serviced) by the server. In order to do so, the IDL file must be compiled. This results in stub code for the client (so we can invoke the methods without worrying about the underlying communication) and skeleton code for the server (which is the basis for our communication on the server side). We'll explain that CORBA is both platform and language independent. This can only work if the parameters and return types of the methods are transported over the network in a portable format. Conversion from a native type to a portable IDL type is called marshalling, while conversion back to a native platform/language type is called unmarshalling.

CORBA
for Delphi and JBuilder

This day is focused entirely on CORBA, especially on CORBA support and implementation details found in Borland Delphi and JBuilder. A solid introduction is followed by the design of a practical real-world CORBA application implemented in Delphi 5 Enterprise and JBuilder 3.5 Enterprise. The CORBA application is a (multi-user) electronic personal Diary, that can be used to check other people's diaries, make appointments, etc. Especially handy in corporate environments where clients are not always working in the same (physical) office. We'll implement the CORBA Server in Delphi, followed by a CORBA Client in Java, another Server in Java and finally a CORBA Client in Delphi that talks with both CORBA Servers, using two portable computers (running WinNT4 and Linux) connected to each other (one with Delphi on WinNT, another with JBuilder on Linux).

Keywords: Delphi, JBuilder, CORBA, IDL, Client Stubs, Server Skeletons, Type Library, ObjectPascal, Java, N-Tier, IDL-2-Java, IDL-2-PAS, Distributed Internet Applications

No prior knowledge of CORBA is required, but some ObjectPascal and/or Java knowledge is welcome. An in-depth technical paper, including full source code, will be given to all attendees of this Clinic.
