I've got an RMI call defined as:
public void remoteGetCustomerNameNumbers(ArrayList<String> customerNumberList, ArrayList<String> customerNameList) throws java.rmi.RemoteException;
The function does a database lookup and populates the two ArrayLists. The calling function gets nothing. I believe this works with Vector types.
Do I need to use the Vector, or is there a way to get this to work without making two calls. I've got some other ideas that I'd probably use, like returning a key/value pair, but I'd like to know if I can get this to work.
Update:
I would accept all of the answers given so far if I could. I hadn't known the network cost, so It makes sense to rework the function to return a LinkedHashMap instead of the two ArrayLists.
As Tom mentions, you can pass remote objects. You'd have to create a class to hold your list that implements Remote. Anytime you pass something that implements Remote as an argument, whenever the receiving side uses it, it turns around and makes a remote call back to the caller to work with that object.
