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>
