Re: Session Tracking
Write a service on Server side which extends RemoteServiceServlet.
Create an object of type HttpSession as a member.
Write methods to serAttribute and getAttribute.
On client side. Inject the service and call setAttribute and
getAttribute methods wherever you want to add data to session or read
data from session.
Refer sample code below:
SessionService ( On server side)
import java.awt.List;
import javax.servlet.http.HttpSession;
import com.google.gwt.user.server.rpc.RemoteServiceServlet;
@SuppressWarnings("serial")
public class SessionImpl extends RemoteServiceServlet implements
ISession {
public static HttpSession httpSession;
@Override
public String getStrAttribue(String attribute) {
httpSession = getThreadLocalRequest().getSession(true);
return (String) httpSession.getAttribute(attribute);
}
@Override
public void setAttribue(String attribute, String attValue) {
httpSession = getThreadLocalRequest().getSession(true);
httpSession.setAttribute(attribute, attValue);
}
}
To use session (on client side)
@Inject
public ISessionAsync session;
session.setAttribue("User","Sujit",new AsyncCallback() {
@Override
public void onSuccess(Void
result) {
//some event
}
@Override
public void
onFailure(Throwable caught) {
// TODO Auto-generated
method stub
}
});

String to Object Structure in GWT
Hi All, I am relatively new to GWT. I have input as a string and i want to convert it into object structure. I was wondering how it can be done in GWT. Example String - *(node1(node2(node3) (node4)) (node5))* "node1" has 2 children "node2" and "node5" "node2" has 2 children "node3" and "node4" More like converting a string into binary tree object.

Re: GWT application freezes when new version is deployed while using it
Joe, We've done something similar. Rather than show a pretty dialog, we embedded some JSNI code in the onAsyncCallFail call. This shows a standard "window.confirm" dialog, then calls $wnd.location.href = href (I seem to recall window.location.reload didn't work). We also deploy in the wee weekend hours as well. I'm liking a lot of the suggestions here, particularly the one about a heartbeat call. The problem I've been wrestling with is: Whenever we want the user to use the new version, we have to wait until they actual do something (i.e. make an RPC call or hit a code-split point). Which means they're trying to get something done and we're interrupting them. A heartbeat mitigates this a little. And assuming we structure things properly, we could notify the user of the new version without actually forcing them to reload. Maybe with a message at the top. I believe Google Groups does this now, yesno? That's the theory anyway...

I am not good in css, is

is equal to just one css class? not any special meaning for the prefix
.gwt-MenuBar, that is
we can rename it as
.gwt-MenuBargwt-MenuItem will not any different?

Re: the output of DialogBox is very strange
I don't think setSize is really supported for the content area of the
DialogBox since setSize is inherited from UIObject. I believe the
size you're setting is the actual dialog box's outer dimensions (ie.
the DecoratorPanel's table) and not your content's dimensions.
What you'll really want to do is have your dialog box's main content
widget sized how you want it and let dialog box size itself based on
that - as RKP Pisters suggested.
