Invoking existing instance from a process without correlation

Question

Hi,
I want to find out if I can do this.
Suppose that instance A was created by others. Instance B of different process wants to invoke instance A. But they do not have a correlation.
This is a part of problem that we want to solve to fix issues in deployed process. Instance A is waiting for user response and we have been invoking this instance A from Java code.
But we want to have a intermediate bpel process B to call instance A. Java code is going to call process B. Because process A is deployed without correlation and active in production, we cannot use correlation to find instance.
I may be able to use programmatic approach using InstanceHandle. But I want to find a way to invoke this in bpel.
Can you give me some hint?
Thanks,
Imju

Answer 1

If my method is now defined as so;
public <T extends GenericDaoImpl> T getDao( Class<T> daoClazz )
return daoClazz.newInstance();
The IDE flags up an error "This method must return a result of type T"
So I think I'm missing something. I have defined an abstract generic DAO helper class to be extended by child DAOs;
public abstract class GenericDaoImpl<T, PK extends Serializable>
CRUD methods
findBy(...) methods
where T is the class type & PK the primary key.
So presumably my getDao(...) method should be defined as;
public <T extends GenericDaoImpl<T, PK>> T getDao( Class<T> daoClazz )
return daoClazz.newInstance();
But it then cannot resolve PK to a type. I think I'm either trying to impose a type on the signature when
it should (obviously?) be generic, or presuming that it will evaluate my generic type which I have somehow
not exposed to the method / signature.
Am I missing something subtle or just being stupid.
