Hello,
I'm writing a blog entry about setting up a GWT development environment for Eclipse WTP + Maven.
As a bonus I planned to add JRebel integration to the GWT devmode.
The project is at: http://jvminside.googlecode.com/svn/trunk/jvminside-gwt-wtp-maven-integration (the rebel.xml file contains absolute pathes but later I will use the maven plugin)
My initial code is:
public class GwtDemo implements EntryPoint {
@Override
public void onModuleLoad() {
RootPanel.get().add(new Button("Click me!", new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
Window.alert("It's working!");
}
}));
}
}
Then I change the class to:
public class GwtDemo implements EntryPoint {
public interface A {
String getMessage();
}
@Override
public void onModuleLoad() {
RootPanel.get().add(new Button("Click me!", new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
Window.alert(new A() {
@Override
public String getMessage() {
return "123";
}
}.getMessage());
}
}));
}
}
Something happens
[INFO] JRebel: Reloading class 'com.jvminside.blog.gwtwtpmaven.client.GwtDemo$1'.
but I get an error in the GWT console (see below).
It doesn't matter if I run the gwt application from Eclipse or command line Maven (using mvn gwt:run).
Maybe is this code modification unsupported by JRebel? If this is the case then I would expect a more informative error message.
Thanks for your help!
Regards:
Norbert Sándor
