如何在tomcat部署javabean和jsp文件&&发布web application，看似容易调通有点........

1.修改conf\server.xml中的
 
 
 把注释去掉,把docbase改为发布目录
2.如果没有使用servlet,filter,taglib等东西的话,web.xml可以为空
3.在/WEB-INF/classes下放入。class文件,/WEB-INF/classes目录需要在classpath中声明
4.myBeans.java编译好了应该放在/WEB-INF/classes目录下

按您说的做了 真的很有效谢谢 但是我调试第一个bean的时候出现了麻烦程序如下：MyBeans的程序：public class MyBeans
{
String str = "hello world";
public String getStr()
{
return str;
}
public void setStr(String str)
{
this.str = str;
}
}
testbeans.jsp:
<html>
<body>
<jsp:useBean id="bean" scope="application" class="MyBeans"/>
<%
String strOut = bean.getStr();
%>
methord 1:
output1: <%=strOut%> 
output2: <%=bean.getStr()%>

<%bean.setStr("hello");
%>
 methord2: 
output:<jsp:getProperty name="bean" property="str"/></body>
</html>我按照您的意思部署了相关文件但我在地址栏敲入：
http://localhost:8080/myjsp/testBeans.jsp时出现如下错误提示：

MyBeans.java编译成MyBeans.class后放在web-inf/classes下应该没问题
我把web-inf  写成了web_info  我现在改正了：）但是问题仍在继续：（我的myBeans.java和testBean.jsp都没有变  部署按照您的意思但是我敲入

package bean; //这里加一个包
public class MyBeans
{
String str = "hello world";
public String getStr()
{
return str;
}
public void setStr(String str)
{
this.str = str;
}
}
<jsp:useBean id="bean" scope="application" class="MyBeans"/>
这句改成
<jsp:useBean id="bean" scope="application" class="bean.MyBeans"/>
编译MyBeans.java时使用：javac -d . MyBeans.java
谢谢了   问题真的解决了但我不明白为什么非要把myBean.class放在web-inf的
一个包里面呢  放在web-inf下面不行吗？？？如果您能解答我这个问题就再好不过了
使用BEAN，是从一个包里引用一个类，不能单独调用一个类。
哥们看了你你帖看得出你和我一样白痴，我现在在看乐思的JSP编程指南，也是满头雾水，给你我的QQ希望你能瞧得起一齐探讨114593629 你只要说明是csdn 朋友，一、我一定加你
看看tomcat的文档吧，一切都会明白的
楼上兄弟
哪里有tomcat的文档？
