1) No, the coordinate system you need to use, depends on your data.
I can't tell you what coordinate system your data is in, you have to ask the
data supplier.
2) I have no idea. My guess is that MapGuide won't render anything and
log an error in the error log file.
I would not count on this working.
3) Likely because you have not entered a coordinate system in the
MapDefinition.
4) Perhaps your data is outside of the display range.
Eg. you are displaying an area out in the ocean.
Again, ask the data supplier what the coordinate system is, and what
bounds it has.
You may need to explicitly set up your Oracle database with the correct
coordinate system:

Hi Kenneth,
Thanks for your reply.
Think is that i don which coordinate system is being used in the GIS tables
am using.But from the option provided by the maestro - " fetch the
coordinate system found in feature " -- i got the coordinate sytem being
used in tables provided to me..
The xml file follows...

This is what i got ....
1.can you please now which coordinate system ?
http://n2.nabble.com/file/n4016757/coordinatesystem.bmp
2. What if i ignore entering coordinate system while creating mapdefinition
?
3.I found that when try to get map.MapSRS value ,it returns empty string ,
what is the reason ?
4.If i tried to copy content of <CoordinateSystemName> to <CoordinateSystem>
tag of mapdefiniton , map does not appear ?
