I've seen this solution which may works in ArcObjects for VB/.Net:

How to overwrite a shapefile or feature class using arcobjects

When I try to convert it into Java, I get a ClassCastException on the IDataset cast.

Here is my code:

IWorkspace workspace = ... IWorkspace2 workspace2 = (IWorkspace2)workspace; if(workspace2.isNameExists(esriDatasetType.esriDTFeatureClass, featureClassName)) { IFeatureWorkspace featureWorkspace = (IFeatureWorkspace)workspace; // ClassCastException here IDataset featureClassDataset = (IDataset)featureWorkspace.openFeatureClass(featureClassName); if(featureClassDataset.canDelete()) { featureClassDataset.delete(); } else { // alert: the feature class exists but couldn't be deleted } } IFeatureClass featureClass = featureDataset.createFeatureClass(...);

Does anyone know how we can't use the IDataset interface for a feature class as in VB?

How to delete a feature class in Java else?

I found a solution: the problem came from the way I created the IWorkspace object. The best way to do it in ArcObjects API for Java is:

 IWorkspaceFactory workspaceFactory = new FileGDBWorkspaceFactory(); IWorkspaceName workspaceName = workspaceFactory.create(parentDirectory, gdbName, null, 0); IName name = (IName)workspaceName; IWorkspace workspace = new Workspace(name.open());

even if in the ESRI documentation, it's written to use new IWorkspaceProxy(name.open()) (I think that's en error).
