Please provide some more information about what is going on. -- i m creating a model on a traindataset. the model is getting created (i.e a .mod file is created). When i m tring to apply that model on other sample datadataset by ModelApplier operator of rapidminer i m getting the error.
Are you? There is no ModelApplier on the stack trace. I only see the ModelLoader.
Does the model get serialized? If yes, are you using compatible versions on both sides? -- the model is getting serialized. What do u mean by compatible versions on both sides??
I mean the common notion of compatibility when speaking about Java object serialization. Admittedly, if that was the problem, you would probably get a different exception.
Are you sure your web container uses the same class loaders for both classes? -- yes
Absolutely? Otherwise I cannot imagine why the ContainerModel cannot be cast to IOObject, because it inherits from IOObject.
Could it be that you have several versions of the two classes (ContainerModel and IOObject) on the classpath which are being confused?
You did not answer my question whether anything went through a WebService.
