Re: [Ikvm-developers] Custom Datatype Issue

If you add the follow lines then you will see where the 2 instances of the same class are loaded.
 
System.out.println( StructureReturnDTO.class.getCLassLoader() );
Object obj = x.get(0);
System.out.println( obj.getClass().getCLassLoader() );
 
If it is the same class then it must be the same instance of class loader.

Casting error StructureReturnDTO is .NET class data type ,we have created .net dll from a java jar which holds the this
structure.
And invoke method which acctually returns the StructureReturnDTO a java class data type.

Which error do you receive?
 
If it is a ClassCastException then it can be that you have 2 classes with the same name from different classloaders.

Class cls = ucloader.loadClass("ToXml");
object jarObj = cls.newInstance();
Class[] paramClassType = new Class[1];
paramClassType[0] = typeof(string);
Method method = cls.getMethod("cobolParser", paramClassType);
object[] param = new object[1];
param[0] = folderPathToParse;
