GWT Client Properties / Options / Variables
Hi! I am building a GWT app which must connect to a different server hosted in the same container. I need some place I can put the server address, ensuring it is accessible from the client code and also that it is easily configurable. What are my options for doing this in GWT, using as little HTTP overhead as possible? Apologies if I've missed anything obvious!

Re: GWT Connection to DB
Hey, You can use GWT RPC to handle server side logic like connecting to and interacting with a database. Be warned, if you choose to use Hibernate as an ORM, there is a steep learning curve. Hibernate may drive you crazy in the beginning, but once you understand all the unintuitive nuances, it rocks. Still GWT is not immediately well suited to work with Hibernate. Since everything on the client side of a GWT application is compiled into JavaScript, there are serialization problems when sending Hibernate objects to the client side. If you want to use Hibernate, I suggest also using Gilead to solve this problems. However, again since the client side is all compiled into JavaScript, no matter what you do, you will not be able to invoke any Hibernate related functionality on the client side. Remember, you can only reference classes on the client side that are implemented in GWT's JRE Emulation Reference: http://code.google.com/webtoolkit/doc/latest/RefJreEmulation.html You're in for a very long haul if you choose to use Hibernate. It's very sophisticated, but you might want to start out with a simpler setup such as using JSON / PHP / MySQL. Instead of using GWT RPC, just make direct Asynchronous HTTP requests for server side PHP using GWT's RequestBuilder object. Your PHP files will connect to and interact with the database. PHP has numerous built in functions for interacting with a MySQL database. Hope that helps! -Lyden On Jan 19, 1:38 am, Saurav Sarkar saurav.sark...@gmail.com wrote: Hi All, I am new to GWT.I installed the google plug-in for Eclipse and also the Window builder.

Hey Again, GWT is client side only. There are no GWT widget that have built in server side functionality. Check out Apache Struts, Apache Wicket, and Apache Click.

Deployment: Choosing a Servlet Container and a Comet Framework
Hi all, I'm in the final stages of developing business management software for the company I work for. My project uses GWT 2.0 (might upgrade to 2.1), Hibernate 3.6, MySQL 5.1.46, and Gilead for GWT/Hibernate Serialization. Now it's time for me to start thinking about deployment, and I was hoping to solicit some advice on which Servlet Container to use. I don't have any experience with setting up and configuring a servlet container. Also I will not be using App Engine. Their website and this app will reside on GoDaddy's servers. I'm under a time crunch, but I'm also still considering replacing some client/server polling with a Comet (Server/Push) framework. Any advice on which framework to use would be most appreciated. Debating between: 1. gwteventservice 2. gwt-comet 3. gwt-comet-streamhub 4. rocket-gwt Lastly this is probably a very stupid question, but is there a way to package my app up along with the servlet container from GWT's embedded Jetty Server, and just host that container rather than go through the process of setting up and configuring a container like Tomcat? I'm guessing there are a number of reasons why, even if I could, I wouldn't want to do this... All in all, whichever container is the quickest and easiest to setup and configure for a beginner is going to be my choice.

Confusing Problem With Overlapping Widgets
Hi,
I am currently working on a GUI using GWT and I am experiencing a
problem with overlapping widgets. Hopefully the images I provided
below will make it clear.
First I have a SimplePanel, containing a VerticalPanel which has both
a Button and a Label. It looks like this: http://goo.gl/j1Yi
Next I click the Button. The ClickHandler code is:
@Override
public void onClick(ClickEvent event) {
SimplePanel anotherSimplePanel = new
SimplePanel();
SimplePanel.add(new Button(New Button));
simplePanel.setWidget(anotherSimplePanel);
}
But the outcome looks like this: http://goo.gl/ErHS
Why is the new button overlapping the old stuff? Should it be replaced
entirely?
The widgets behind New Button cannot be clicked or used, it's like
only the graphical parts remain.
Any advice would be much appreciated!

GWT 2.1 M3 SimplePager Question
Hi!
I have a CellTable, SimplePager and ListDataProvider setup in my view
constructor like so:
public MyView {
cellTable = makeCellTable();
simplePager = makeSimplePager(cellTable);
initWidget(uiBinder.createAndBindUi(this));
listDataProvider.addDataDisplay(cellTable);
}
My list has 25 items in it, and simplePager is setup with these
options:
simplePager.setDisplay(cellTable);
simplePager.setPageSize(10);
simplePager.setRangeLimited(false);
However, on initially loading the SimplePager widget in my browser for
the first time I see:
1-10 of 10
instead of
1-10 of 25 (as you'd expect for a list with 25 items)
The widget fixes itself when I click the forward arrow and then go
back.
Any ideas what could be wrong?
Thanks!

Thanks for the reply. Generators seem like a lot to swallow. I'm trying to introspect a set of DTO's that I want to marshall to and from a database.

Re: Database and GWT
You have a couple of options: 1. Hibernate (or some other ORM tool) 2. JDBC 3. PHP and JSON Be prepared, the Hibernate learning curve is substantial. If you use Eclipse, you will need to install a slew of plugins for integrating Hibernate and whichever build tool you pefer, (Maven, Ant, etc.).

Re: Reflection: Get Variable Name
Also, it seems like people have made GWT Reflection Frameworks. I found one named GWT Reflection. Then there's gwt-ent or SmartGWT I guess. Any thoughts on using one of these routes?

Re: GWT Hibernate Project Structure
Thanks Yau, That would be great. Any info you could give me on how you setup your project would be great. Are you using Eclipse? Also, is it the correct procedure to place your Hibernate jars and dependencies in the war/WEB- INF/lib directory and then add them to the build path? Thanks for your help!

Re: how to resize a DockLayoutPanel pane using gwt 2.0 and uibinder
Hi,
I faced the same problem and I solved it by creating the following
utility class:
import com.google.gwt.dom.client.Style.Unit;
import com.google.gwt.user.client.ui.DockLayoutPanel;
import com.google.gwt.user.client.ui.Widget;
public class DockLayoutPanelUtils extends DockLayoutPanel {
private DockLayoutPanelUtils() {
super(Unit.PX);
}
public static double getWidgetSize(Widget widget) {
return ((LayoutData) widget.getLayoutData()).size;
}
public static void setWidgetSize(Widget widget, double size) {
((LayoutData) widget.getLayoutData()).size = size;
}
}
Because it extends the DockLayoutPanel it has access to the protected
LayoutData object. With that object you can change the size (width or
height depending on the widget) of the widget. So you need to provide
the widget that was set with the addNorth, addSouth, addWest or
addEast method or the widget that you defined in the uibinding xml
file between the north, south, west or east element.
Don't forget to execute the forceLayout() method on the
DockLayoutPanel after changing the size of a widget.
Regards,
Maurice
