Problems with calling COM+ components from BizTalk 2004 Orchestration
|

| 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?
