404自动向Glassfish部署servlet后

glassfish servlets java

Ceilingfish · 技术社区 · 16 年前

我试图将我创建的servlet部署到Glassfish应用程序服务器上,但我似乎遇到了一些障碍。代码可以很好地部署到auto-deploy文件夹,部署后,以下内容将写入日志文件:

[#|2009-03-16T13:41:29.303+0000|INFO|sun-appserver2.1|javax.enterprise.system.tools.deployment|_ThreadID=23;_ThreadName=Timer-7;|[AutoDeploy] Selecting file /opt/glassfish-2.1.b60e/domains/imageTransformer/autodeploy/image-transformer.war for autodeployment.|#]

所以没有明显的错误,但是在那之后,通过访问servlet应该绑定到的路径,我得到了404。还有其他的步骤需要我去做吗?

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>

这个部署有几个问题。首先,需要在 WEB-INF 目录,命名 sun-web.xml . 其内容必须符合以下几点:

<?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>

它似乎有可能变得比这复杂得多(见 the documentation )

其次,我必须更改 web.xml 文件,因此它相应地读取:

<?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>

注意标题表明这是servlet规范2.4。

最后,似乎您不能直接访问这个servlet;您必须预先准备 MyServlet/ (或servlet特定的名称)到路径的开头。所以要访问这个servlet需要您访问 /MyServlet/hello .

我修改了web.xml;我只是添加了ORDS配置目录的完整路径。

<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>

不管sun-web.xml是否存在,它都可以工作。
