Problems passing class objects through GWT RPC

Question

I\'ve run through the Google Web Toolkit StockWatcher Tutorial using Eclipse and the Google Plugin, and I\'m attempting to make some basic changes to it so I can better unde

Answer 1

Yes, it is sure that we need to use the Serialization for getting the server objects to the client. These modile?? file settings won't work to use the Stock class in the client side.

In your case you have only one class Stock and you can create a StockClient in client side. It is easy. But what will be the solution if anyone having more classes. Something like the properties of this class are also some other type of classes.

Example: stock.getEOD(date).getHigh();

getEOD will return another class with the given date and that class has the getHigh method.

What to do in such big cases? I don't think creating all classes implementing serialization in client side is good for that. Then we have to write code in both server and client. all classes two times.

Keying off of rustyshelf's answer above ...

In my case I needed to edit the ModuleName.gwt.xml file and add the following:

<source path='client'/>
<source path='shared'/>

I created my project with the New->Web Application Project wizard but unchecked the Generate project sample code option. I then created the shared package. Had I not unchecked that, the package would have been created for me and the xml file modified per the above.
