[解决办法]
<%
fb.setfirstproperty("my first");
% >
<%=fb.getfirstproperty()% >
</html >
改了也用JSP动作看看
[解决办法]
我记的javabean一定要放在一个包里才可以的。 你试试把bean放到一个包里再在jsp页面里去调用试试。。。。
[解决办法]
楼上的是正解。
一般javaBean是需要放到一个包里的。
------
解决的办法：
修改firstjavabean.java，添加在一个包中。
jsp页面调用其相应包名+firstjavabean
[解决办法]
你的<%@ page contentType="text/html;charset=gb2312" % >
<jsp:useBean id="fb" scope="session" class="firstjavabean" / >
<html >
应该改成
<%@ page contentType="text/html;charset=gb2312" % >
<html>
<jsp:useBean id="fb" scope="session" class="firstjavabean" / >
