Hi,

I am doing a shortestpath() function of oracle spatial on a roadnetwork and
storing the result set into a path table (SHORTEST_PATH) and path link
table. It is a simple line. Following is the style sheet i used for the road
table and works fine But for the SHORTEST_PATH table, it visualizes an empty
screen.

Can any body give a clue, where i am making the mistake?

cheers,

Hum, I see nothing obviously wrong... I would check the geometries in shortest_path are valid ones, then check the bbox is correct (maybe you're just looking at the wrong area?) and finally, if that does
not work, enable full logging in configuration/server and see if
the detailed log provide any clue
