getResponse和的返回类型应该是什么submit，并且两者都是必需的？
在firstForm或中输入猜测时SecondForm，如何将该猜测回显到同一网页？
要么使用 ajax，所以不重新加载同一页面
或者
加载一个新页面，guessResults.xhtml例如，哪个 echo 是猜测。
支持豆，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;
}
}

我正在使用 CDI 在 Glassfish 上运行 facelets，所以我正在使用@Named而不是 @ManagedBean- 上面的一些文档更适合 . @ManagedBean，但我不确定这有多重要。
目标是比“hello world”好一步，“hello world，你的猜测是”会是一个很好的结果。如果有特定的手册，我不介意针对该特定文档的 RTFM。Oracle 文档可能是 facelets 的最佳选择？
