Question

我遇到了一个小问题。我尝试在我的一个页面中使用viewScoped managedBean。程序如下：

我的豆位置

我的豆子：

@ManagedBean(name = "diagramManager")
@ViewScoped
public class DiagramManagerManagedBean {
    private String toto = "toto";

    public String getToto() {
        return toto;
    }
}

但是在我的页面中，如果我尝试＃{diagramManager.toto} 我只收到错误500＆＃39; 错误500：在上下文中找不到名称comp / env / com.asdmt.bean.DiagramManagerManagedBean＆＃34; java：＆＃34; 。我已经尝试在faceconfig.xml中声明了managedbean，我也遇到了同样的错误。我在wepshere 6.1使用JSF2
