Like Rich states, maybe you can attempt to access the service before really needing it. Perhaps you can alter the code snippit found in the API documentation for ESRI.Request to verify that the service is up and running: esri.request Thank you evtguy. That's what I needed.

Just make any kind of request to the service and handle the response or (importantly in your case!) the error. Thanks you geos_rfleet.

Hello there! I would appreciate it very much if you guys help me solve this issue: I'm trying to create FeatureLayer like this featureLayer = new esri.layers.FeatureLayer(featureServiceURL, featureLayerOptions); the line above gives me an error: Unable to draw graphic (geometry:null, symbol:null): Unable to complete operation. That's because featureServiceURL points to the server which does not exist or is inaccessible. My question is: how to find out if the service is OK before creating FeatureLayer - in other words, how to validate service prior to FeatureLayer please? Thanks in advance, Klim

Hello, I would appreciate it very much if you give me a clue of how to delete lines from polyline. Please see attached picture. The ABCD polyline is a result of creating FLAT LEFT sided buffer from original line AB, and converting the buffer polygon into ABCD polyline. I was able to to delete BC, CD and DA lines from ABCD polyline by dissolving ABCD with "Split Line At Vertices" tool, selecting and deleting unwanted lines. This is an automated process, and it takes forewer when processing freeway lines because of large number of small links (dissolving result) to process. Instead of processing those numerous tiny links, I would like to process only 4 corresponding lines at points A, B, C and D. I can do it by using "Split Line at Point" tool, which takes polyline and set of points as an input. My question is how to get those A, B, C and D points from ABCD polyline please? Thank you in advance.
