【问题描述】：

我是 JSF 新手，我正在构建一个使用 facelets 创建的应用程序。
这是我的模板

MasterSearch.java 哪个是 bean

public class MasterSearch {

    long serviceNumber;
    String rank;
    String fullName;
    String CNICNumber;
    String phoneNumber;
    String emailAddress;

    public long getServiceNumber() {
        return serviceNumber;
    }
    public void setServiceNumber(long serviceNumber) {
        this.serviceNumber = serviceNumber;
    }
    public String getRank() {
        return rank;
    }
    public void setRank(String rank) {
        this.rank = rank;
    }
    public String getFullName() {
        return fullName;
    }
    public void setFullName(String fullName) {
        this.fullName = fullName;
    }
    public String getCNICNumber() {
        return CNICNumber;

    public void setCNICNumber(String cNICNumber) {
        CNICNumber = cNICNumber;
    }
    public String getPhoneNumber() {

    public String getEmailAddress() {

    }
    public void setEmailAddress(String emailAddress) {
        this.emailAddress = emailAddress;
    }

    public String findPerson(){

        return "personfound";

    }

}

现在，当我运行此代码（实际上是 masterp.xhtml）时，它会显示完美的输出并准确加载，但它会在控制台 i-e 中引发异常

我认为因此它没有提交我的按钮的操作

&lt;h:commandButton id="btnMasterSearch" type="submit" value="Search" styleClass="submitButton" action="#{masterSearch.findPerson}"&gt; 出现在 MasterSearch.xhtml 中。我在 SO 上发现人们遇到了这个问题，但我无法找到并理解一个好的解决方案。
请帮助谢谢

【问题讨论】：

  • 我不明白你为什么将纯 HTML 与 Facelets 混合使用。
  • “在响应提交后无法创建会话”似乎在页面响应完成后，在您尝试创建会话的代码中的某处。我建议检查支持 bean。
  • 对，但是我应该在我的支持 bean 中检查什么？我的意思是他们只是拥有 getter setter 的豆子。@thinksteep
  • 你没有业务逻辑的bean吗？
  • 还没有 - 我只是在导航 - 让我添加我的 bean 和 faces-config.xml

【解决方案1】：

这是 Mojarra 中的一个已知错误。它已被报告为问题 2215 和 2277，并且自 Mojarra 2.1.8 以来已得到修复。所以如果你至少升级到 2.1.8，那么这个问题应该会消失。

这个问题的原因可以解释如下：Mojarra 试图尽可能地推迟会话创建。会话应该只在真正需要的时候创建。其中，当需要写入&lt;h:form&gt; 的JSF 视图状态时，通常发生在关闭&lt;/h:form&gt; 的渲染过程中。但是，在相对较大的页面上，其中关闭的&lt;/h:form&gt; 出现在 2KB 的书面 HTML 之后，那么创建会话为时已晚。要创建会话，服务器即需要设置 cookie。但是，要设置 cookie，响应不应该已经提交（cookie 即需要进入响应标头中）。服务器默认配置为每写入 2KB 的 HTML 就刷新响应。

如前所述，此问题自 Mojarra 2.1.8 起已修复。您可以下载最新版本here。

  • thx @BalusC - 我是 JSF 的新手，所以我不明白为什么这个 mojarra 问题出现在我的应用程序中，因为我使用的是 glassfish 3.1.2，而且我没有为 JSF 包含任何 jar因为 glassfish 已经为此提供了支持。所以如果我不使用 mojarra 那么它来了？为了解决这个问题，在下载它的 2.1.11 版本后我现在应该做什么......我应该在我的类路径中包含那个 javax.faces-2.1.11.jar 吗？
  • JSF 捆绑在 Glassfish 中。 Glassfish 3.1.2 使用 Mojarra 2.1.6。只需将/glassfish/modules 文件夹中的javax.faces.jar 文件替换为较新的版本即可。
  • 爱你，你太棒了 :) 因为我还没有该代码，但我希望当我尝试这个时它会好的 :) :*
  • 不客气。顺便说一句，如果您对 Glassfish 服务器安装没有完全的管理员控制权，那么您还可以通过将较新的 javax.faces.jar 文件放在 webapp 自己的 /WEB-INF/lib 文件夹中并编辑 /WEB-INF/glassfish-web.xml 文件以添加以下两个新条目：&lt;class-loader delegate="false" /&gt;&lt;property name="useBundledJsf" value="true" /&gt;.
  • 此属性是否会强制我的应用使用我的项目 jsf.faces.xx.jar 而不是 glassfish jar ？有时我们会遇到此类问题...
