Hi,

I want to call a method in a COM+ component.
Even though I mark the class as Serializable I still get the following
error:

TxOrchestration1.odx(256): a non-serializable object type
'ComPlusLib.ComPlus ComPlusVar' can only be declared within an atomic scope
or service

How do I call a managed COM+ component (ServicedComponent) from a BizTalk
2004 orchestration ?

TIA
Detlef Hahn

Here is the code snippet for the COM+ component:
namespace ComPlusLib
{

[Guid("0C885210-ED4C-48aa-BF11-266FE56FF7BE")]
public interface IMyInt
{
void Test(XmlDocument doc);
}

[Guid("8F72A130-75A0-4512-A55B-292587150FC4")]
[JustInTimeActivation(true)]
[Transaction(TransactionOption.Required)]
[Serializable]
public class ComPlus : ServicedComponent  , IMyInt
{

public void Test(XmlDocument doc)
{
//...
}

}
}

If you reference any other .dll's that are not serializable, the assembly
you created, will not be seralizable either.  If you use a long running
transaction for your orchestration, you can then use an atomic scope for
declaring and calling your .dll.

You are using a non-serializable class XmlDocument in your component.
Is there any particular reason why the method call can't be done in an
atomic scope? Is it a very time-consuming method?
