第一次

javax.servlet.ServletException: Wrapper cannot find servlet class www.net.csdn.servlet.LoginServlet or a class it depends onorg.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:103)org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:293)org.apache.coyote.http11.Http11AprProcessor.process(Http11AprProcessor.java:879)org.apache.coyote.http11.Http11AprProtocol$Http11ConnectionHandler.process(Http11AprProtocol.java:617)org.apache.tomcat.util.net.AprEndpoint$Worker.run(AprEndpoint.java:1774)java.lang.Thread.run(Unknown Source)

root cause

java.lang.ClassNotFoundException: www.net.csdn.servlet.LoginServletorg.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1680)org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1526)org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:103)org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:293)org.apache.coyote.http11.Http11AprProcessor.process(Http11AprProcessor.java:879)org.apache.coyote.http11.Http11AprProtocol$Http11ConnectionHandler.process(Http11AprProtocol.java:617)org.apache.tomcat.util.net.AprEndpoint$Worker.run(AprEndpoint.java:1774)java.lang.Thread.run(Unknown Source)

note The full stack trace of the root cause is available in the Apache Tomcat/6.0.39 logs.

刷新后

HTTP Status 404 - Servlet LoginServlet is not available

type Status report

message Servlet LoginServlet is not available

description The requested resource is not available.

Apache Tomcat/6.0.39

除了会是有由于web.xml配置问题，还有web.xml的路径问题，今天我又发现了 <servlet-class>net.csdn.servlet.LoginServlet</servlet-class>可以运行， <servlet-class>www.net.csdn.servlet.LoginServlet</servlet-class>会出现bug,路径只能支持三位吗？以后我会继续关注这个问题.
