<H3>XmlRpc++ Library</H3>
<P>This is version 0.7 of XmlRpc++, an implementation of the <A HREF="http://www.xmlrpc.org">
XmlRpc protocol</A> written in C++, based upon Shilad Sen's excellent <A HREF="http://py-xmlrpc.sourceforge.net">
py-xmlrpc library</A>. XmlRpc++ is designed to make it easy to incorporate
XmlRpc client and server support into C++ applications. Or use both client and
server objects in your app for easy peer-to-peer support.
</P>
<H3>Features</H3>
<UL>
<li>
<STRONG>Easy</STRONG> This library is easy to incorporate into C++
applications. No other libraries are required, other than your system's socket
libraries. Simple XML parsing and HTTP support are built in.<br>
<li>
<STRONG>Fast</STRONG> All IO is non-blocking, so a slow client or
network will not slow down the server.<br>
<li>
<STRONG>Portable</STRONG> Written in standard C++ to the POSIX and Windows
sockets APIs. You do need a fairly recent compiler (g++ 3.1 or MSVC++ .Net or
MSVC++ 6 with the <A href="http://www.dinkumware.com/vc_fixes.html">STL patches</A>.)
</li>
<li>
<STRONG>Free</STRONG> This library is released under the <a href="http://www.gnu.org/">
GNU</a> <a href="http://www.gnu.org/copyleft/lesser.html">LGPL</a>.<br>
<br>
</li>
</UL>
<P> </P>
<h3>Changes</h3>
<UL>
<li>
Better handling of fault responses: server methods can throw an
XmlRpcException to return a fault and XmlRpcClient has a new method to
test whether the last response was a fault.</li>
<li>
Support for system.listMethods and system.methodHelp from the introspection
API.</li>
<li>
Support for system.multicall to process multiple requests in a single transaction.</li>
<li>
Fixed a problem in the XmlRpcServer destructor (it should not have been deleting the methods).</li>
<li>
The server ensures a valid result value is returned even if the method does not
set the result. The default result is an empty string.</li>
<li>
Doxygen comments in header files and a doc target in the makefile.</li>
</UL>
<P>
<P> </P>
<h3>Installation</h3>
<P>
There are VC++ 6 and VC++ .Net project files building on Windows. If you are
using VC++ 6, you should apply SP3 and the fixes at <A href="http://www.dinkumware.com/vc_fixes.html">
http://www.dinkumware.com/vc_fixes.html</A>. Be sure to set the appropriate
code generation switches. In particular, ensure that the runtime library
(single/multi-threaded, static library/DLL) used is the same for the XmlRpc++
code and whatever application it will be linked to.</P>
<P>
For Linux, Solaris, and other Unix-like platforms there is a GNU Makefile which
can be edited to suit your system. Specify your C++ compiler, compiler flags,
and your system's socket libraries.
</P>
<p>In the test directory there are various test programs that are built by default.
To verify that the library built correctly, you can start the HelloServer
example:<br>
<pre>HelloServer 8000
</pre>
and the HelloClient example in another terminal window:<br>
<pre>HelloClient localhost 8000
</pre>
<P>
You should see two Hello messages and a sum displayed (amongst a bunch of debug
output). You can also try the XML server validator program (eg, "Validator 80")
and then attempt to connect to it from <A href="http://validator.xmlrpc.com">http://validator.xmlrpc.com</A>
(if you have access to the internet and are not behind a firewall etc).

<P>Although no code was re-used, the design and structure of the library is based
upon the py-xmlrpc library implementation.<BR>
