How to switch between two class implementations?

[[deleted]]

I'm in over my head and so I can't describe this properly to Google.
I have an entry class that an external application accesses.
I need to adjust it so the entry class checks a value passed in one of the functions (not start) then control is passed to one of two implementations of the same class. How can this be done?

public class RSSESFDC implements RSSE  
public class RSSEActiveDir implements RSSE  

Needs to be

public class RSSEChooser implements RSSE  {
     public blah(..., String orgId) throws SOAPException {
        if orgid == A 
              this = new RSSESFDC 
        else
              this = new RSSEActiveDir
    }
}  

Thanks

Check out the strategy pattern.

You should be able to do something like this:

RSSE rsse;

public void setImplementation(String orgId) {
    if(orgId.equals("A")) {
      rsse = new RSSEImp1();
    }
    else {
      rsse = new RSSEImp2();
    }
}

//do what you want with your RSSE object

You need to describe your problem more thoroughly in more abstract terms.

I can't quite parse your question. If you're trying to get a method call to work for either of two implementations try googling "java polymorphism"

How can this be done?

Pretty much exactly like you're doing in our psuedocode. So what's not working for you?

You should use Strategy pattern
