well, I don't really know unless I see your code, and fully understand what you are 
doing.

I don't know why you are storing the template html code in an Oracle procedure. But, 
since I don't know that, I will not attempt to answer that.

the mapextent is used typicall to determine the mapextent of the "next" view 
requested by the user. You use the user's mouse clicks to zoom in or zoom out or 
pan based on that point.. since the mouse click is in imagespace (pixels) you need to 
transform it to mapspace and calculate the new mapextent.

First thing to do might be to see if you are getting everything to work without Oracle 
in between. If it does, there is likely something connected with your putting it all into 
an Oracle proc.
