Question

我尝试将我创建的servlet部署到Glassfish应用程序服务器，我似乎遇到了一些绊脚石。代码部署到auto deploy文件夹，并且一旦部署，以下内容将写入日志文件：

所以没有明显的错误，但之后我从访问servlet应绑定的路径获得404。我需要经历另一个步骤吗？

我的WAR文件中的web.xml如下所示：

<web-app>
     <servlet>
       <servlet-name>MyServlet</servlet-name>
         <servlet-class>my.servlet.MyServlet</servlet-class>
     </servlet>

    <servlet-mapping>
        <servlet-name>MyServlet</servlet-name>
        <url-pattern>/hello</url-pattern>
    </servlet-mapping>
 </web-app>

Answer 1

此部署存在一些问题。首先，需要将第二个配置文件包含在名为WEB-INF的{{1}}目录中。其内容需要与以下内容类似：

sun-web.xml

似乎有可能比这更复杂（见the documentation）。

其次，我必须更改<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE sun-web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Application Server 8.1 Servlet 2.4//EN" "http://www.sun.com/software/appserver/dtds/sun-web-app_2_4-1.dtd"> <sun-web-app error-url=""> <context-root>/MyServlet </context-root> </sun-web-app>文件的标题，因此它会相应地读取：

web.xml

请注意标题，表明这是servlet规范2.4。

最后，您似乎无法直接访问此servlet;您必须将<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" version="2.4"> <servlet> <servlet-name>MyServlet</servlet-name> <servlet-class>my.servlet.MyServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>MyServlet</servlet-name> <url-pattern>/hello</url-pattern> </servlet-mapping> </web-app>（或servlet特定名称）添加到路径的开头。因此，要访问此servlet，您需要访问MyServlet/。

Answer 2

我修改了web.xml;我只是为ords添加了config目录的完整路径。

<display-name>Oracle Application Express Listener</display-name>
<context-param>
    <param-name>config.dir</param-name>
    <!-- Enter the location where configuration settings should be stored -->
    <param-value>/odata/apps/ords/config</param-value>
</context-param>

无论是否存在sun-web.xml，它都能正常工作。

404将servlet自动部署到glassfish之后
