getResponse和submit的返回类型应该是什么，并且都是必要的？
当在firstForm或SecondForm中输入猜测时，如何将该猜测回显到同一网页？
使用ajax，因此不会重新加载同一页
或
例如，加载一个新页面guessResults.xhtml，这就是猜测。
支持bean NextClient：
package dur.beans;
import dur.jpa.Client;
import dur.jpa.ClientFacadeLocal;
import java.util.concurrent.atomic.AtomicInteger;
import javax.ejb.EJB;
import javax.enterprise.context.ApplicationScoped;
import javax.inject.Named;
@Named("nextClient")
@ApplicationScoped
public class NextClient implements NextClientLocal {
@EJB
private ClientFacadeLocal clientFacade;
private AtomicInteger next = new AtomicInteger(1009);
private AtomicInteger guess = new AtomicInteger(0);
private final boolean correct = true;
@Override
public String getNext() {
next.addAndGet(1);
Client client = clientFacade.find(next.intValue());
return client.toString();
}
@Override
public void setGuess(int guessInt) {
guess = new AtomicInteger(guessInt);
}
@Override
public int getGuess() {
return guess.intValue();
}
//not sure what do with these methods
@Override
public String getResponse() {
return "the guess of " + guess.intValue() + " is " + correct;
}
@Override
public String submit() {
return "the guess of " + guess.intValue() + " is " + correct;
}
}

另见：
JSF 2.0 commandButton do nothing
https://javaserverfaces.java.net/nonav/docs/2.0/pdldocs/facelets/h/commandButton.html
http://docs.oracle.com/javaee/7/tutorial/doc/jsf-facelets003.htm
我在Glassfish上使用CDI运行facelets，因此使用@Named和不 @ManagedBean - 上面的一些文档更适合{{1但是我不确定那有多重要。
目标比“你好世界”更好一步，“你好世界，你的猜测是”将是一个好结果。如果有特定的手册，我不介意该特定文档的RTFM。 Oracle文档可能是facelets的最佳文档吗？

使用支持bean NextClient：

将提交的值与鸟一起输出到响应中。将结果输出到同一页面可能更有意义，但这已足够。
