Does GWT buffer or stream the servlet response?
Hi, I want to know if Jetty that comes with GWT buffers or streams the data that is written to the servlet response? (i.e. when you call servletResponse.getOutputStream() or servletResponse.getWriter() ). That is important as when this is streamed this should on the one hand be faster and on the other hand the response will be committed after the first byte was written. Can this be configured?

I looked a bit more at it and there's actually nothing that strange here. One could say the code could be better optimized but that's it. This method is used to generate a signature for a type that will change whenever its serialization changes. When a type has no CustomFieldSerializer, its fields are used; otherwise, because we cannot tell which fields will be serialized, the signature for the type is the signature for its CustomFieldSerializer. That's the reason for the recursive call. It's not expected then that the CustomFieldSerializer itself has a CustomFieldSerializer. If you want to make it better, then add a boolean argument to the method to tell whether a CustomFieldSerializer should be used or not (or maybe split the method in two), so that when computing the signature for the CustomFieldSerializer we don't look for the CustomFieldSerializer's CustomFieldSerializer. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

If your backend is written in Java, then this makes sense since you can work with the same POJO's on the back and front end.

Re: Does GWT buffer or stream the servlet response?
There are always bufferes here and there to increase performance. Take a look at the jetty documentation and the configuration of jetty's connectors (send buffer). You also have ServletResponse.setBufferSize(). Take a look at Jetty's source code to see how it uses this buffer size. It also somewhat depends on the client. If you do a HTTP 1.0 request and your servlet does not set a Content-Length header then the servlet container probably has to buffer the whole response in order to compute the Content-Length as this header is mandatory for HTTP 1.0. In case of HTTP 1.1 you don't have to set a Content-Length header but use chunked transfer encoding instead. -- J. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

Re: Code Splitting Simple Example Still getting Thrown into Left Overs
I haven't looked in detail at your code, but you might experiencing the
same problems I had, see this issue (and the linked forum post):
ISSUE http://code.google.com/p/google-web-toolkit/issues/detail?id=7874

I would greatly appreciate some input here. I am trying to use the below
references to implement Code Splitting w/ Activities/Place/GIN
HOWEVER, I can't get anything to work. Not even a simple solution which I
'think' should be working regardless of my current implementation for
A/P+GIN...

method I am trying to use)
Other References:

My Hope is that I am doing something blatantly wrong. I have a simple
Split Point that creates a string and custom widget (very simple) and shows
a PopupPanel. However it still gets thrown into the Left overs.
My end goal is the complete solution to MVP/GIN (which originally didn't
work so I thought I'd try this simple solution - no luck so I'm coming to
you guys:)
I've attached a piece of the Compile Report and including the below links
for better reference:

Button b = new Button(Click Me, new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
GWT.runAsync(Application.class, new RunAsyncCallback() {
@Override
public void onSuccess() {
String sp3 = 3sp33sp
33sp33sp33sp33sp33sp33sp33sp33sp33sp33sp33spp3;
VerticalPanel vp = new VerticalPanel();
vp.add(new InlineLabel(sp3));
MySPTestWidget t = new MySPTestWidget(); // Simple Composite
with unique string to test SP
vp.add(t);
PopupPanel p = new PopupPanel();
p.setWidget(vp);
p.center();
}
@Override
public void onFailure(Throwable reason) {
Window.alert(SP Application Failed);
}
});
}
});
Any thoughts on why the simple (and possibly the ultimate goal of
MVP/GIN-CodeSplitting) is not working?

Binding Driver To A List
Hello all,
first of all I'm sorry if I sound incompetent but the truth is I'm fairly
new to GWT. So here's what I want to do: I have a database with different
itemtypes (Product, User, Country, etc...).
I want to make a GWT application that edits these item types. For that
purpose I have created a dto called EntityDto which contains a list of
SectionDto, which in itself contains a list of PropertyDto. So the
PropertyDto is a representation of each of the item's properties
(Product.code for instance). The PropertyDto has the following signature:
public class PropertyDto implements Serializable {
private String id;
private String value;
/* getters/setters */
}
So I have managed to display a form with TextField for the Entity's
properties and their values. Now I want to submit the changed values and
persist them in the database. As I was reading on the internet this is
achieved using a combination of a Driver and Editor. My problem is that I
don't have a real POJO to use any of the existing drivers. All I want is to
map the field with id code, for instance, to the String in
EntityDto.PropertyDto.value (for whichever PropertyDto has the same id).
Is there any solution to this? How would you create a form that is not
backed by a bean but instead by a dynamic map or a list for instance?
Thank you for you help.

In any case, you'll have to do it manually.
If you need to use the Editor framework, and/or your scenario is complex
enough to make it worth it, then you can use a
ValueAwareEditorSectionDto: in setValue you loop over the PropertyDto-s
and push their values to the corresponding text box, and in flush() you do
the reverse (from text box to PropertyDto).

Re: Unable to intregrate gwt-ext with gwt 2.5
Isn't it an issue of gwt-ext and it is better to ask their support if it should work with gwt 2.5? Though I believe a little bit more detailed problem description is required in order to get a reasonable help.

Re: Binding Driver To A List
Hi Thomas,
yes that sounds like exactly what I need. What I don't really understand is:
--
you loop over the PropertyDto-s and push their values to the corresponding
text box
--
how do I gain access to the text-boxes? Do you have any example I can refer
to?
Many Thanks
