java - JSF + RichFaces 在我的页面中提供 HTTP 状态 404

Question

可能这是一个缺乏注意力的问题，如果是这样，请原谅我，但我看不出我做错了什么，花了我一下午的时间，我需要你的帮助。

我正在做一个 JSF + JPA + RichFaces 应用程序，它非常简单。我做了 JPA 项目，进行了测试，然后进行了 JSF 项目，进行了测试，一切工作正常，但是当我将 RichFaces jar 粘贴到 WEB-INF/lib 文件夹中时，甚至在我进行任何更改之前，正在工作的页面就停止了，现在我得到一个 HTTP 状态 404 页面，就像我输入了错误的地址一样，但我使用的地址与以前相同。

这是我的 web.xml

我认为我的 JPA 项目与此错误没有关系，因为它是一个独立的项目并且工作正常。

我的文件夹结构类似于

Monaco/
    WebContent/
        cadastro/
            pessoa/
                erro.jsp
                inserir.jsp
                listar.jsp
                test.jsp
        WEB-INF/
            lib/
                richfaces-api-3.3.2.SR1.jar
                richfaces-impl-3.3.2.SR1.jar
                richfaces-ui-3.3.2.SR1.jar
            faces-config.xml
            web.xml
        index.jsp

网址http://localhost:8080/Monaco/faces/cadastro/pessoa/listar.jsp曾经在 RichFaces jars 之前工作过，但现在我得到了:

HTTP Status 404 - /Monaco/faces/cadastro/pessoa/listar.jsp
--------------------------------------------------------------------------------
type Status report
message /Monaco/faces/cadastro/pessoa/listar.jsp
description The requested resource (/Monaco/faces/cadastro/pessoa/listar.jsp) is not available.
--------------------------------------------------------------------------------
JBoss Web/2.1.2.GA

我尝试了很多网址变体，例如:

• http://localhost:8080/Monaco/faces/cadastro/pessoa/listar.jsf
• http://localhost:8080/Monaco/faces/cadastro/pessoa/listar.faces
• http://localhost:8080/Monaco/cadastro/pessoa/listar.jsp
• http://localhost:8080/Monaco/cadastro/pessoa/listar.jsf
• http://localhost:8080/Monaco/cadastro/pessoa/listar.faces

在所有这些中，我收到相同的错误(应该没问题)，但我无法理解为什么它停止只是因为我添加了 RichFaces jars...

谢谢家伙!

再见。

Answer 1

您需要将网页内容文件放入 /faces 根文件夹中，路径与 URL 中的路径完全相同。

另一种方法是将 /faces/* 的 url-pattern 替换为 *.jsf，这样您就可以在不使用/faces 路径，例如:http://localhost:8080/Monaco/cadastro/pessoa/listar.jsf。顺便说一句，您不需要需要将实际的 .jsp 文件重命名为 .jsf。

如果您想阻止直接访问 JSP 文件(否则将能够请求 .jsp 文件并遇到 RuntimeException: FacesContext not found)，那么您最好将文件(包括文件夹结构)移动到 WEB-INF 文件夹中。

希望这有帮助。

编辑:您添加了应用程序服务器日志。第一个问题的根本原因如下:

java.lang.ClassNotFoundException: org.apache.commons.digester.Digester

这是相当不言自明的:运行时类路径中缺少提到的类。正如包名称已经暗示它是 Apache Commons Digester，您可以从 http://commons.apache.org/digester 获取它。 。将其放入运行时类路径 (WEB-INF/lib) 中并重新启动。看看后续的错误是否会消失(可能是由同一问题间接引起的)。如果没有，请返回并编辑问题中的堆栈跟踪(不要忘记选择它并按代码按钮 (0101011010) 或按 Ctrl+K)。
