配置问题汇总

1在编译java文件时为什么会软件包不存在? 解决办法可以在classpath设置路径 也可以在命令中加入-classpath 路径

 

我在运行servlet在eclipse下预览时，页面显示：    HTTP Status 404 - /servlet/HelloServlet

----------------------------------------------------------------------------

----

type Status report

message /servlet/HelloServlet

description The requested resource (/servlet/HelloServlet) is not available.

----------------------------------------------------------------------------

----

Apache Tomcat/5.0.28      

    <!-- The mapping for the invoker servlet --> <!--     <servlet-mapping>         <servlet-name>invoker</servlet-name>         <url-pattern>/servlet/*</url-pattern>     </servlet-mapping> -->  将注释去掉！

将D:/Program Files/Apache Software Foundation/Tomcat 5.0/webapps/ROOT/WEB-INF

中的WEB中内容进行修改！    <servlet>         <servlet-name>HelloServlet </servlet-name>         <servlet-class>HelloServlet </servlet-class>     </servlet>

    <servlet-mapping>         <servlet-name>HelloServlet</servlet-name>         <url-pattern>servlet/HelloServlet</url-pattern>     </servlet-mapping>

<!-- JSPC servlet mappings end -->

</web-app>
