I'd like to try and integrate more java for addins and engine, but I always run into strange problems - the last engine app I tried to write in Java gave me 'cannot find main class' errors (I was using jre1.6, but have java 1.8 installed, perhaps that is an issue).  Also, I have problems where my buttons don't show up in the Java Commands or any other category I enter. Have you experienced anything like this with Java? ... View more

Hi everyone, I have a script that checks the percentage of overlap between two polygons. The code below was working fine in 9.3 but now in 10.1 it crashes every time on the pTopologicalOperator.Intersect line with an error of "Exception from HRESULT: 0x80040215." I looked this code up on the Web but only found a few results and none of them matched my problem. I also followed the ESRI instructions to convert the hexidecimal number but I got no results when using ErrorLookup. Any help is greatly appreciated.

I'm using Java with arcobjects.  Prints "Trying to create a gp object...", but never gets to "..Done!".  Any suggestions?  Have lots of other arcobjects code that works.  For some reason can't get this one line to work!  Its a drag as its kinda an important one! ... public createGp() {   try{    dealWithLics();    System.out.println("Trying to create a gp object...");    GeoProcessor gp = new GeoProcessor();    System.out.println("..Done!");   } catch (Exception e) {    e.printStackTrace();   } } ... I often avoid the GeoProcessor object at all costs, and stick to pure ArcObjects.  I've had issues with it in the past where it does the same thing randomly.  What are you doing with the GeoProcessor object? ...

Thanks for your effect kyanuk1. Ur searching layer level but its better feature level... For example I am having 20 layers but point intersecting 2 or 3 layer ..so I need point intersecting objects Not sure I understand... do you want to find all features intersecting an area (buffer) around a single point?  From specific layers? ...

Ok, you solved it. The class name in the config.xml needs to include your package name, which I said before. In the config.xml gui or the source, change the class value to:  my.pkg.Button1.java Updated the config, and exported and reinstalled the addin... still nothing. ... View more

Also, the thing that is not the same in your environment is you have a value of "default" for the <AddInID> tag, whereas I have a value that looks like this: <AddInID>473e3189-0145-1000-5000-0a09186f0000</AddInID> The Add-in project wizzard places that value there for me, I don't do anything to generate it. Why is that? Good question... doesn't look like mine is being generated... not sure why?  Perhaps that may be an issue, however, the addin itself is being recognized in ArcMap, just not the button. EDIT:  It has something to do with the fact that the template being autogenerated is for 10.0 ... [ATTACH=CONFIG]32963[/ATTACH] ... View more

A screenshot of your project expanded would help. Your java source files are in a folder called:  src or java ? Did you place the Button1 class in a package of your own? Such as: My Project[INDENT]java (or src)[/INDENT] [INDENT=2]your.package.name[/INDENT] [INDENT=3]Button1.java [/INDENT] Expanded project: [ATTACH=CONFIG]32958[/ATTACH] ... View more

Look at the source of your config.xml. <ArcMap>   <Commands>     <Button ... in here is where you want to check the following:   </Commands> 1. The category value is correct. 2. The class value contains the full package name of the class, if you put your Button1 class in a package. 3. If you used an image for your button, make sure the path is correct. Here is what is created: [ATTACH=CONFIG]32955[/ATTACH] [ATTACH=CONFIG]32956[/ATTACH] I've noticed that even with the SDK for 10.1, the version it creates is 10.0 ... I've tried changing that to 10.1 before and after exporting the addin, but the Java Commands category still is not showing up. ... View more

Thanks for your reply....    Your searching Single feature layer.. I need to find intersecting features(all layers features) around a point feature. So use that method when iterating a list of IFeatureLayers from the map: if you want to get the layers in a map: List<IFeatureLayer> myLayers = new List<IFeatureLayer>(); var layerUID = new UID(); layerUID.Value = "{40A9E885-5533-11D0-98BE-00805F7CED21}"; var eLayer = _ArcMap.Document.FocusMap.get_Layers(layerUID, true); var layer = eLayer.Next(); while (layer != null) {      var featureLayer = (IFeatureLayer)layer;      myLayers.Add(featureLayer);      layer = eLayer.Next(); } then use the method I posted before on this list on your feature: List<IFeature> intersectedFeatures = null; foreach(var featureLayer in myList) {      intersectedFeatures.AddRange(myFeature.SelectByGeometry(featureLayer, 10)); // 10 is an arbitrary buffer size.. you would use whatever you want here } ...

Thanks for your Reply....    I tired but it select only one feature. please send any sample code... If I'm understanding you correctly, you could use a SpatialFilter with a search distance to get all intersecting features from that point, i.e.:        public static List<IFeature> SelectByGeometry(this IFeature feature, IFeatureLayer fc, double searchDist) {             IFeatureCursor curs = null;             List<IFeature> features = new List<IFeature>();                         try {                 SpatialFilter sf = new SpatialFilterClass();                 sf.SpatialRel = esriSpatialRelEnum.esriSpatialRelIntersects;                 ITopologicalOperator top = (ITopologicalOperator)feature.ShapeCopy;                 sf.Geometry = top.Buffer(Convert.ToDouble(searchDist));                                 curs = fc.Search(sf, false);                 var boundFeat = curs.NextFeature();                 while (boundFeat != null)                 {                     features.Add(boundFeat);                     boundFeat = curs.NextFeature();                 }                 return features;             }             finally             {                 if (curs != null) Marshal.ReleaseComObject(curs);             }         } ...

bump... looking for some more technical assistance with this issue ... View more

I can't guarantee that the connection method will be OSA; it might be database. I'm relying on clients of my code to provide a valid connection string, so it might be a passage from Finnegans Wake for all I know. I could write a bunch of code to validate the connection string passed, but my thinking is that this is something that Esri should be checking and returning an error for. Since it doesn't seem that Esri does this, I was hoping to find a way to timeout and throw an exception, rather than having to write and maintain a whole bunch of string validation code. Yeah... such is often the case with ArcObjects... sorry I can't be of more help.  I'll often find writing my own solution for these things work out better in the end, anyway.  I'm still struggling to get a Java ArcMap addin to even show up in the commands window after its been installed! ...
