原因是：

  1. JSF将页面组件结构存储在HttpSession中，
  2. 如果页面内容很大，并且之前没有创建session，可能已经写入了一些response，就会出现上面的错误，

所以解决办法是在打印 Facelet (/JSP) 页面之前创建会话。一个粗略的例子可能是这样的：

@PostConstruct
void initialiseSession() {
    FacesContext.getCurrentInstance().getExternalContext().getSession(true);
}

/napu

The reason is that:

  1. JSF stores the page component structure in HttpSession
  2. If the page content is very large and the session has not been previously created, some response may have been written and the error above happens

So the solution is to create the session before the Facelet (/JSP) page is printed. An crude example could be like:

@PostConstruct
void initialiseSession() {
    FacesContext.getCurrentInstance().getExternalContext().getSession(true);
}

/napu

[已解决]

花了几天时间来诊断这个问题，但最终我能够解决这个问题。

它实际上是@ViewScoped，它有一个未序列化的托管属性DAO对象。因此，在呈现视图之后，facelets 也会产生此异常，但 JSF 视图已经呈现，这就是显示此异常的原因。

解决方案：使所有对象在@ViewScoped bean中序列化，并将未序列化的标记为“瞬态”，就像在我的例子中它是JSF中的DAO对象@ViewScoped< /代码>。

[SOLVED]

It took days to diagnose this problem, but finally I am able to solve this problem.

It was actually @ViewScoped and it has a managed property DAO object which was not serialized. So after view is rendered, facelets also produce this exception, but JSF view already rendered and that's why this exception showed.

Solution: Make all objects serialized in @ViewScoped bean, and mark "transient" who are not serialized like in my case it was DAO object in JSF @ViewScoped.

我将其放入 web.xml 中来解决我的一个应用程序的问题。

<context-param>
    <param-name>javax.faces.STATE_SAVING_METHOD</param-name>
    <param-value>client</param-value>
</context-param>

但奇怪的是，我在同一个 glassfish 实例上托管了几个其他应用程序，这些应用程序不需要 web.xml 中的这个 voodoo。

我强烈相信这不是解决方案，因为对我来说，为什么这个特定的应用程序需要它而其他应用程序不需要它，这对我来说没有任何意义。但目前它有效。

I put this in my web.xml to solve the problem for one of my apps.

<context-param>
    <param-name>javax.faces.STATE_SAVING_METHOD</param-name>
    <param-value>client</param-value>
</context-param>

What is weird though is that I have several other applications hosted on this same glass fish instance that doesn't require this voodoo in the web.xml.

I strongly want to believe this is not the solution, cos it doesn't make any sense to me why this particular app requires it and the others didn't. But for now it works.

这也发生在我身上。

我曾经使用 Mojarra 2.1.13，将其更新到 2.1.29 后，问题自行解决，无需对我的代码进行任何更改。

It was happening to me too.

I used to have Mojarra 2.1.13 and after updating it to 2.1.29 the problem solved itself, without any changes in my code.

我也发生过这个错误，但与创建自定义错误页面有关。我生成了一个简单的错误页面：

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://xmlns.jcp.org/jsf/html"
      xmlns:f="http://xmlns.jcp.org/jsf/core"
      xmlns:jsf="http://xmlns.jcp.org/jsf"
      xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
      xmlns:p="http://primefaces.org/ui">

    <f:view contentType="text/html;charset=UTF-8" encoding="UTF-8">
        <h:head>

        </h:head>
        <h:body>
            <!-- start writing here your components -->
        </h:body>
    </f:view>

</html>

并且我已配置 web.xml 以将 404 错误分派到此页面：

<error-page>
  <error-code>404</error-code>
  <location>/error_404.xhtml</location>
</error-page>

当我尝试引发该错误时，我遇到了相同的错误。

It happened this error to me also, but related with the creation of a custom error page. I've generated a simple error page:

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:h="http://xmlns.jcp.org/jsf/html"
      xmlns:f="http://xmlns.jcp.org/jsf/core"
      xmlns:jsf="http://xmlns.jcp.org/jsf"
      xmlns:ui="http://xmlns.jcp.org/jsf/facelets"
      xmlns:p="http://primefaces.org/ui">

    <f:view contentType="text/html;charset=UTF-8" encoding="UTF-8">
        <h:head>

        </h:head>
        <h:body>
            <!-- start writing here your components -->
        </h:body>
    </f:view>

</html>

And I've configured web.xml to dispatch 404 errors to this page:

<error-page>
  <error-code>404</error-code>
  <location>/error_404.xhtml</location>
</error-page>

When I try to provoke the error I bump over the same error.
