方法一把輸出字串當javascript執行，方法二只是把方法一包到PhaseListener，為什麼要這樣包還不太清楚，所以先用方法一
try {
RWT.getResponse().getWriter().println("alert('123');");
} catch (IOException ex) {
ex.printStackTrace();
}
RWT.getLifeCycle().addPhaseListener(new PhaseListener() {
private static final long serialVersionUID = 1995219943700635190L;
@Override
public PhaseId getPhaseId() {
return PhaseId.RENDER;
}
@Override
public void beforePhase(PhaseEvent event) {
try {
RWT.getResponse().getWriter().println("alert('1');");
} catch (IOException e) {
e.printStackTrace();
}
}
@Override
public void afterPhase(PhaseEvent event) {
try {
RWT.getResponse().getWriter().println("alert('2');");
} catch (IOException e) {
e.printStackTrace();
}
RWT.getLifeCycle().removePhaseListener(this);
}
});
Step 1. Install plugin from update site
Eclipse => Help => Install New Software => Add
Name: Google app Engine
Location: http://dl.google.com/eclipse/plugin/3.6
Step 2. Create GAE project
File => New => Project
type filter text: Web Application Project
type project name, package and uncheck "Use Google Toolkit"
Step 3. Specified applications for this project
Package Explorer => this project => war => WEB-INF => appengine-web.xml
<application>name of your application</application>
Step 4. Test and Deploy
Just click the button "Run" or "Deploy App engine project" on toolbar
Test URL: http://localhost:8888/ (Default)
GAE URL: http://name of your application.appspot.com

}
