初学,想写个最简单的bean,老是报同一个错

[fyzeng]

换了几个例子,报的都是同一句错
就是这句:<jsp:useBean id="s" scope="page" class="hello"/>

org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: 2 in the jsp file: /hello.jsp

hello这个类里应该建在包的下面.
就是在java程序最顶上加一句话package xxx;
然后在/web-inf/classs/下面建目录xxx.把class文件拷贝进去.
jsp改为:
<jsp:useBean id="s" scope="page" class="xxx.hello"/>
重新运行ok

晕，找不到类啊！你看看你的class="hello"给确定对了，有包的要加上去啊，
