Hi @Martin Staudigel you only can include DTD in the XSD if you define it using specific flags.

The solution is to create a new class to import the schema in XSD programatically. This is an example of the code:

Class XML.SchemaReader Extends %Persistent

{
ClassMethod ImportClasses(fileName As %String = "C:\Temp\example.xsd") As %Status
{
#include %occInclude
#include %occSAX
		#dim sReader as %XML.Utils.SchemaReader = ##class(%XML.Utils.SchemaReader).%New()
		#dim features as Filero.DataType.String
		set sReader.SAXFlags = $$$SAXFULLDEFAULT-$$$SAXVALIDATIONREUSEGRAMMAR
		set sReader.MakePersistent = 0
		set sReader.MakeRelationships = 0
		set sReader.GenerateXMLNILNOOBJECT = 1
		set sReader.GenerateXMLNIL = 1
		set sReader.KeepEmptyClasses = 1
		set features("BINARYASSTREAM") = 1
		quit sReader.Process(fileName,"ImportedScheme",.features)
}
}

This code will create a package "ImportedScheme" in your IRIS

As the creator of the idea, you have all my support! The localized versions are really confusing with literal translations that have no sense.

If you execute the bat file from the command line of Windows...does it work? Maybe the PATH to the java bin folder is not accessible from the Ensemble user.
