Content Overview</a></h3>
<p>The Orber documentation is divided into three sections:
</p>
<ul>
<li>
<p>PART ONE - The User's Guide
<br>
Description of the Orber Application including IDL-to-Erlang
language mapping, services and a small tutorial demonstrating
the development of a simple service.</p>
</li>
<li>
<p>PART TWO - Release Notes
<br>
A concise history of Orber.</p>
</li>
<li>
<p>PART THREE - The Reference Manual
<br>
A quick reference guide, including a
brief description, to all the functions available in Orber.</p>
</li>
</ul>

</ul>
<h4>ORB Kernel and IIOP Support</h4>
<p>The ORB kernel which has IIOP support will allow the creation
of persistent server objects in Erlang. These objects can also
be accessed via Erlang and Java environments. For the moment a
Java enabled ORB is needed to generate Java from IDL to use
Java server objects (this has been tested using OrbixWeb).</p>
<h4>Interface Repository</h4>
<p>The IFR is an interface repository used for some type-checking
when coding/decoding IIOP. The IFR is capable of storing all
interfaces and declarations of OMG IDL.</p>
<h4>IDL to Erlang Mapping</h4>
<p>The OMG IDL mapping for Erlang, which is necessary to access the
functionality of Orber, is described, The mapping structure is
included as the basic and the constructed OMG IDL types
references, invocations and Erlang characteristics. An example is
also provided.</p>
<h4>CosNaming Service</h4>
<p>Orber contains a CosNaming compliant service.</p>
<h4>Resolving Initial References from Java or C++</h4>
<p>A couple of classes are added to Orber to simplify initial
reference access from Java or C++.
</p>
<p><strong>Resolving initial reference from Java</strong> <br>
A class with only one method which returns an IORon the
external string format to the INIT object (see "Interoperable
Naming Service" specification).</p>
<p><strong>Resolving initial reference from C++</strong> <br>
A class (and header file) with only one method which returns
an IOR on the external string format to the INIT object (see
"Interoperable Naming Service" specification).</p>
<h4>Orber Stub/Skeleton</h4>
<p>An example which describes the API and behavior of Orber stubs and skeletons. </p>
<h4>CORBA Exceptions</h4>
<p>A listing of all system exceptions supported by Orber and how one should
handle them. This chapter also describe how to generate user defined
exceptions.</p>
<h4>Interceptors</h4>
<p>Descibes how to implement and activate interceptors.</p>
<h4>OrberWeb</h4>
<p>Offers the possibility to administrate and supervise Orber via a GUI.</p>
<h4>Debugging</h4>
<p>Describes how to use different tools when debugging and/or developing
new applications using Orber. Also includes a FAQ, which deal with
the most common mistakes when using Orber.
