<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>So is the portability issue. From the
deployment perspective, MapGuide Server looks impressive. It can be deployed to
Windows and other OS. But, if we take a look at source code, we can easily
conclude that we are doing it in hard way. For example, we can easily find the
macros like <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>Using such macros assumes that the
developers know the programming syntax on all supporting OS platforms for the
functions they want to write. And, this expectation is certainly too high. The
interface abstraction is needed to make it independent to the OS platforms, at
least in programming level for majorities.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>To me, binary expansion and interface
abstraction are the two key issues to prevent MapGuide Server from expansion.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I am trying to develop several new services on MapGuide
Server. The ideal approach would be the dynamic approach. It can be described
as: <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> 1. Create a new service
project separately from the existing code base;<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'> 2. Let MgServer.exe load the
service DLL at runtime based on the serverconfig.ini.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>This approach can avoid recompiling the entire code base for
the new services.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>But, by studying MapGuide Server source code, I found that
Server Core project has the links to all other 7 services. Obviously, the
existing services were not developed using this dynamic loading approach
(correct me if I am wrong). So, here is the question. Does MapGuide server
support dynamic loading for the newly-developed service DLL? <o:p></o:p></span></font></p>
