我正在尝试使用MyFaces v 2.1与WebSphere Application Server Community Edition v3.0.0.1和Eclipse Juno创建一个简单的JSF Web应用程序,但是当我尝试运行该应用程序时,返回以下错误

我正在审查当前的JSF项目,其中web.xml配置包含:

• FacesServlet(已配置*.xhtml)
• 该 com.sun.faces.config.ConfigureListener

我正在使用JSF 2.2和Mojarra实现.

我很困惑ConfigureListener.配置中是否需要此类？这门课的目标是什么？我找不到任何信息,班级几乎没有javadoc.

如果我删除此配置,一切似乎都以相同的方式工作.因此,我想ConfigureListener可以或应该删除,但我不确定.

我有一堆热切的 ApplicationScoped托管bean.其中一些通过ManagedProperty注释注入到其他注释中,形成依赖树.每个依赖bean在构造后操纵其父级.

但是,似乎为每次注射创建了一个新实例,从而使之前的操作无法完成.根据我的理解,ApplicationScopedbean应该只创建一次.我误解了或者为什么会这样？是因为他们渴望吗？

这是一个例子:

ParentBean.java

package example;

import javax.annotation.PostConstruct;
import javax.faces.bean.ApplicationScoped;
import javax.faces.bean.ManagedBean;

@ManagedBean(eager = true)
@ApplicationScoped
public class ParentBean
{
    static int initCount = 0;

    // ...

    @PostConstruct
    public void init()
    {
        ++initCount; // Will end up being between 1 and 3. Expected always 1.

        // ...
    }
}

Child1Bean.java

package example;

import javax.annotation.PostConstruct;
import javax.faces.bean.ApplicationScoped;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ManagedProperty;

@ManagedBean(eager = true)
@ApplicationScoped
public class Child1Bean
{
    @ManagedProperty("#{parentBean}") ParentBean parentBean;

    public ParentBean …
