I finally figured this out. After trying your suggestion with no change in results (still no log messages showing), I took a look at the default launch configuration. It has -logLevel=ERROR. changing this to INFO shows the output of GWT.log. I apologize for wasting your time.

Ian, thanks, I am using GXT. I ripped all that out, and still no
messages are showing. I've got this reduced to a single "Hello,
world" application. Looks like we are not permitted to attach files
here, so here is the source. I really don't remember, but I think
this was generated via MyEclipse with GWT Designer:
[CODE]
package com.masergy.test.client;
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.core.client.GWT;
import com.google.gwt.user.client.Window;
import com.google.gwt.user.client.ui.Button;
import com.google.gwt.user.client.ui.ClickListener;
import com.google.gwt.user.client.ui.RootPanel;
import com.google.gwt.user.client.ui.VerticalPanel;
import com.google.gwt.user.client.ui.Widget;
import com.google.gwt.user.client.ui.Composite;
/**
* Entry point classes define onModuleLoad().
*/
public class ImageViewer extends Composite implements EntryPoint {
private VerticalPanel pagePanel = new VerticalPanel();
private Button clickMeButton;
public void onModuleLoad() {
String aVersion = GWT.getVersion();
GWT.log("ImageViewer.onModuleLoad GWT version: " + aVersion,
null);
RootPanel rootPanel = RootPanel.get();
pagePanel.setSpacing(10);
pagePanel.setWidth("735px");
rootPanel.add(pagePanel);
clickMeButton = new Button();
pagePanel.add(clickMeButton);
clickMeButton.setText("Version: " + aVersion);
clickMeButton.addClickListener(new ClickListener() {
public void onClick(Widget sender) {
GWT.log("ImageViewer clickMeButton.onClick", null);
Window.alert("Hello, GWT World!");
}
});
}
}
[/CODE]
And here is the gwt.xml file:
[CODE]
[/CODE]
Appreciate any pointers.

Re: GWT.log doesn't generate messages to console
Sorry, forgot to mention I'm using GWT 1.5.3. Scott, thanks for the pointer. Since our real projects are employing GWT successfully, I'll just stick with that.

GWT.log doesn't generate messages to console
I work with GWT (and GXT) from within MyEclipse. We have 2 large production apps with a server component, and GWT.log works fine with them. Then I have a small, no function app with no server component that I use to test out some UI things - my playground app. GWT.log messages do not show up in the console for this playground app. If I force an error, those error messages show up in the console. If I call GWT.getVersion() and put the result into a GUI element, I'm seeing the correct version string. I found a forum message reporting this behavior back in 2007 but no response. Any ideas on why GWT.log doesn't work for this small app? Thanks. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Let's do the time warp baby > Ross, you are thinking too narrowly. Think of a single code base. When it runs on the desktop, it has access to local file system and other OS facilities. When it runs in a browser like GWT does today, it degrades nicely and only loses minimal functionality. Write once, run anywhere. But if you'd rather not expand your horizons, that's fine.

I known nothing about pyjamas, but I'm intrigued about what lkcl has been discussing. What he has done (and is suggesting could be done with GWT) is to have a browser-based application (via a Java->Javascript translater like GWT) and a desktop application (via a direct Java runtime) derived from the *same* codebase. Why bother, you ask? For your mobile or infrequent users, perhaps a browser-based solution is preferable. At the same time, people who sit in front of a stationary desktop system may prefer the look and feel of a desktop application. With the pyjamas approach, you can satisfy both constituents with a single set of code. -- Guy Rouillier --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

How could I get access to web.xml parameters? What is your runtime environment? Under Tomcat, the common way to handle database connections is to create connection pools as a resource, then in your code just obtain a connection from the pool. Your code doesn't need to know the actual pool configuration, nor should it care. -- Guy Rouillier --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

We just finished our first GWT application, and we are pretty seasoned Java developers. The app is pretty simple, and it still took us about 2 months to figure out how we wanted to standardize our approach. I suppose since you'll be doing this yourself, you won't have much discussion on building a platform for your company. But still, just understanding the concepts new to GWT is quite a challenge. In our case, we are persisting data to a relation DB, so we had to figure out how to retrieve that, transform it into something GWT could use, serialize to browser, etc. All standard GWT stuff, but quite a learning curve. Since you've never written programs in C++ either, I'd say you should probably give yourself 6 months for your first Java/GWT app. -- Guy Rouillier --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
