Routing Layer not showing

AzizulAlam1 — Sun, 14 Aug 2011 19:41:33 GMT

Hello,
I am new at ArcGIS flex API. I want to do a basic route task. I have created a route network using network analyst. In ArcMap it is working fine. I have merged all road layer into one layer. It is a very simple polyline data. It has no time, barrier, u-turns or historical traffics data. I have published it into ArcGIS Server with network access. Now when I am changing the rest endpoint in Basic Routing Code of Flex it is not showing the Routing Layer in Browser. When I am clicking for 2 stops it attaching the triangle marker and it is calculating Route (Its showing the busy cursor tool for a long time if I click 2 stop to a far distance or its taking a little time if i click near to each other). I am giving the Coding...

I am attaching the Route and street files. Please help me to learn this Topic.
