Create IMosaicDatasetOperation3 in Java

AndyArismendi1 — Fri, 27 Aug 2021 12:09:41 GMT

Hi, I've never used ArcObjects before but I'm trying to cobble together a proof of concept snippet to reproduce the functionality in ArcPy ExportMosaicDatasetPaths w/ and environment extent by using the ExportItems method on IMosaicDatasetOperation3.

https://desktop.arcgis.com/en/arcobjects/latest/net/webframe.htm#IExportItemsParameters.htm

I created a little test app in NetBeans and added the arcobjects.jar from ArcGIS Engine and got to this point, but got a casting exception. From some examples I saw online it looks like you are supposed to cast the mosaic dataset object to a mosaic dataset operation object but not sure if that works the same for java...

Any help would be greatly appreciated! Here's the code so far -

//Initialize the Java Componet Object Model (COM) Interop.
EngineInitializer.initializeEngine();

// Initialize an ArcGIS license.
AoInitialize aoInit = new AoInitialize();
initializeArcGISLicenses(aoInit);

String fgdb_path = "S:\\Test.gdb";
String md_name = "TestMD";
IWorkspaceFactory ws_factory = new FileGDBWorkspaceFactory();
IWorkspace wksp = ws_factory.openFromFile(fgdb_path, 0);
IMosaicWorkspaceExtensionHelper helper = new MosaicWorkspaceExtensionHelper();
IMosaicWorkspaceExtension ws_ext = helper.findExtension(wksp);
IMosaicDataset md = ws_ext.openMosaicDataset(md_name);
IMosaicDatasetOperation3 md_op = (IMosaicDatasetOperation3)md;

//Exception in thread "main" java.lang.ClassCastException: com.esri.arcgis.datasourcesraster.IMosaicDatasetProxy cannot be cast to com.esri.arcgis.datasourcesraster.IMosaicDatasetOperation3
