Hello everybody,<br><br>I am new to mapguide. I am writing a java thick client map application using MapGuide Open Source as map server. I query images from the map server, this part works pretty well, not  fast enought tough.<br>
<br>My problem is that I also need to be able to read the feature data in order to be able to provide some simplified geocoding service as well, but I can't get the feature reader to work, I also need the tile service because rendering images takes a lot of time and even implementing tile caching in the program is not enough, so I would like to use MapGuide's tile service as well reading tile data through  MgByteReader in a similar way as reading  arbitrary sized images.<br>
<br>I have problem running even the simplest sample codes, eg. map.Open() function throws an exception so I have to use map.Create() to open a map and I am thinking that this might be the root of my problems. <br><br>Here is how my code works: (simplified) I have followed instruction from the GettingStartedGuide.pdf to the letter when installing the MapGuide server<br>
<br>try {<br>            MapGuideJavaApi.MgInitializeWebTier("C:\\webconfig.ini");<br>            MgUserInformation userInfo = new MgUserInformation("Anonymous", "");<br>            mapDefid = new MgResourceIdentifier(<br>
            "Library://Samples/Sheboygan/Maps/Sheboygan.MapDefinition");<br>            MgSite site = new MgSite();<br>            site.Open(userInfo);<br>            String sessionId = site.CreateSession();<br>
            site.Close();<br>            MgSiteConnection siteConnection = new MgSiteConnection();<br>            siteConnection.Open(userInfo);<br>            MgResourceService service = (MgResourceService) siteConnection<br>
                    .CreateService(MgServiceType.ResourceService);<br>            MgMap map;<br>            map = new MgMap();<br>            MgRenderingService renderingService = (MgRenderingService) siteConnection<br>                    .CreateService(MgServiceType.RenderingService);<br>
            MgFeatureService featureService = (MgFeatureService) siteConnection<br>                    .CreateService(MgServiceType.FeatureService);<br>            MgTileService tileService = (MgTileService) siteConnection<br>
                    .CreateService(MgServiceType.TileService);<br>            MgResourceService resourceService = (MgResourceService) siteConnection<br>                    .CreateService(MgServiceType.ResourceService);<br>
            map.Create(resourceService, mapDefid, "MyMap");<br>            /**<br>             * Opening map throws exception<br>             */<br>    //        map.Open(resourceService, "Sheboygan");<br>
            MgResourceIdentifier districtsId = new MgResourceIdentifier(<br>                    "Library://Samples/Sheboygan/Data/VotingDistricts.FeatureSource");<br>            /**<br>             * Selecting features throws exception<br>
             */<br>//            featureService.SelectFeatures(districtsId, "VotingDistricts",<br>//                     new MgFeatureQueryOptions(), "Sheboygan");<br>            /**<br>             * Reading a certain area of the map as an image file stream works fine<br>
             */<br>            MgByteReader reader = this.mapGuideResourceManager<br>            .getRenderingService().RenderMap(map,<br>                    this.mapGuideResourceManager.getSelection(), env,<br>                    (int) renderSpec.getImageSize().getWidth(),<br>
                    (int) renderSpec.getImageSize().getHeight(),<br>                    new MgColor((short) 0, (short) 0, (short) 0xff),<br>                    "JPG");<br>        } catch (MgException ex) {<br>            ex.printStackTrace();<br>
        }<br><br>Any help or ideas would be appreciated, now I am stuck with the development because of these problems.<br><br>Thanks,<br><br>aron deak<br>
