you are <%=sessionBean.getNewName()%>.

</html>
这是JAVABEAN
package Beans;
public class NameBean{
String newname="sss";
public void NameBean(){}
public String getNewName(){
return newname;
}
public void setNewName(String newname){
this.newname=newname;
}
}
问题一：
我运行了JSP后出现页面如下：
Welcome to The UseBean Jsp
May we have your name>
Page bean: hello sss!
Session bean: aha,i remember you. you are sss.
这行是一个文本框和一个按钮
然后我在文本框中输入1111内容后，再按按钮后，应该输出
Welcome to The UseBean Jsp
May we have your name>
Page bean: hello 1111!
Session bean: you are sss.
但是好象不对啊，不知道为什么？请指点
