6 errorsgenxml.jsp与stocks.jsp放在D:\gt3\Tomcat 4.1\webapps\ROOT\jsp\ex下，
PortfolioBean.java与stocks.java放在D:\gt3\Tomcat 4.1\webapps\ROOT\WEB-INF\classes\beans下
classpath为：D:\gt3\Tomcat 4.1\webapps\ROOT\WEB-INF\classes\beans
各位大侠看看问题出在什么地方？谢谢啦！

Answer 1

内容太多，给个例子你看吧，俺的文档：

Answer 2

晕！
不管怎样，谢谢了！
我认为我的问题可能出在package的地方不对！

Answer 3

多发一个，为了要分，在webapps下做如下操作：
stacks -- genXML.jsp
       -- stocks.jsp
       -- WEB-INF -- classes --stacks -- *.class和classes没关，在tomcat的conf下的server.xml中可以
仿照  <Context path="" docBase="ROOT" debug="0"/>
做  <Context path="/stacks" docBase="stacks" debug="0"/>

Answer 4

应该把Stock.java编译后的Stock.class放在WEB-INF 下面
