The biggest challenge in creating a remote interface to match Java code across AJAX is the usually asynchronous nature of AJAX, compared to the synchronous nature of a normal Java call.

DWR solves this problem by introducing a callback function that is called when the data is returned from the server.

Writing JavaScript with DWR

There are 2 recommended ways to make a call using DWR. Either by appending a call options object or a callback function to the parameter list. Call Options Object The recommended syntax is to make use of a call options object that specifies the callback function and other options.

This method has some advantages: Depending on your style it may be easier to read, but more importantly it allows you to specify extra call options. Timeouts and Handling Errors In addition to the callback function you can also specify a timeout, errorHandler, and several other call options.

Since the doSomethingWithPerson method returns 'void' we do not need to use a callback and can just leave it out. If you want to be notified of the completion of a server-side method that returns void then you can include a callback method.
