The following text is what I got from GWT's RCP notes, <http://
code.google.com/webtoolkit/documentation/
com.google.gwt.doc.DeveloperGuide.RemoteProcedureCalls.html>
"For the same reason, asynchronous methods do not have return types;
they must always return void."
So, to use a method with an RPC, am I just doing the following?
in .../client/table.java
public void Request() /* Makes RPC */
{
table = (tableServiceAsync)GWT.create(tableService.class);
ServiceDefTarget endpoint = (table)threatBoard;
endpoint.setServiceEntryPoint(GWT.getModuleBaseURL() +
"table");
}
public void onModuleLoad() {
...
// call loadFromTable using RPC
threatBoard.loadFromSQL(new AsyncCallback()
{
public void onSuccess(Object result)
{
return;
}
public void onFailure(Throwable caught)
{
return;
}
});
// all business logic is in .../server/tableImpl
I'm lost, please guide me.
Thanks
