Well, you surely wouldn't want the server randomly calling the client and popping up dialogs whenever it felt like it in this scenario. Bear in mind I know exactly what you're trying to do, and Tim is pointing you in the right direction.
You still want to do this as a return value from the server; trust me.
Think of it this way. You want extra information [i]as a reaction to[/i] the user entering too [i]little[/i] information. So the user supplies an ID, but didn't supply, say, color. Because of that you want the server to [i]return[/i] your client enough information so that it can ask your user for more. You don't want the server to push a dialog in the user's face--that kind of interaction should always be up to the client.
So here's your client pseudocode:
[code]
Result result = server.addProduct(incompleteInformation);
if (result != null) {
RequiredInformation infoUserNeedsToSupply = result.getRequiredInformation();
if (infoUserNeedsToSupply != null) {
// TODO: build JDialog; get information out of infoUserNeedsToSupply; show dialog
// TODO: when user closes dialog get user info
// TODO: re-call server method with new information
}
}
[/code]
Best,
