Hi, I have started to get intermittent problems when trying to use feature services accessing various data sources from SHP files, ArcSDE to Oracle. When I do something like:
//Creates a new site connection and passes the current session MgSiteConnection mgSiteCon = new MgSiteConnection(); mgSiteCon.Open(new MgUserInformation(oneSpMap.mapSession)); // create a feature service MgFeatureService featureService = (MgFeatureService)mgSiteCon.CreateService(MgServiceType.FeatureService); MgFeatureQueryOptions featureQueryOption = new MgFeatureQueryOptions(); // Get the feature resource for the selected layer MgResourceIdentifier layerFeatureResource = new MgResourceIdentifier(this.resourceId); // create feature reader MgFeatureReader featureReader = featureService.SelectFeatures(layerFeatureResource, className, featureQueryOption); I get the exception thrown: An unclassified exception has occurred - MgFeatureServiceHandler.ProcessOperation() line 83 file c:\osgeo\mapguide_21\mgdev\server\src\services\feature\FeatureServiceHandler.cpp - MgOpSelectFeatures.Execute() line 109 file c:\osgeo\mapguide_21\mgdev\server\src\services\feature\OpSelectFeatures.cpp - MgServerFeatureService.SelectFeatures() line 405 file c:\osgeo\mapguide_21\mgdev\server\src\services\feature\ServerFeatureService.cpp This happens pretty randomnly. It is used in a web application where the user clicks a layer name and it does various feature service queries. Any one of the the 3 feature service queries can throw this exception and at any time. So sometimes on first click, sometimes are clicking many times on various different layers. For this reason I am discounting data issues given the fact it happens on multiple layers and it can read these layers most of the time but this error sometimes happens. Any ideas? Your help is appreciated Colin -- View this message in context: http://n2.nabble.com/Feature-Service-unclassified-exception-happening-intermittently-MG-2-1-tp4099443p4099443.html Sent from the MapGuide Users mailing list archive at Nabble.com. _______________________________________________ mapguide-users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/mapguide-users
