  1.   

    少发了一段代码
    <%@ page contentType="text/html; charset=gb2312" %>
    <%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic"%>
    <%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean"%>
    <%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html"%><html>
    <head>
    <title>查看全部学生</title>
    </head><body>
    <br>
    <br>
    <br>
    <table width="366" height="67" border="1" align="center" cellspacing="0">
    <logic:iterate name="list" id="getlist" type="java.lang.String">
      <tr>
       <TD><bean:write  name="getlist"   /></TD>
      <TD><bean:write property="name" name="getlist"/></TD>
      <TD><bean:write property="pwd" name="getlist"   /></TD>
     
     </tr>
     </logic:iterate>
    </table>
    </body>
    </html>

    首先 你这个问题 出在<bean:write name="getlist" />这里 
    因为getlist并不是一个bean他没有getter or setter方法，他只是把你从action那里传过来的list封装成Object对象放在pageContext里面
    所以才会抛出javax.servlet.jsp.JspException: No getter method for property name of bean getlist这样的异常
    建议你可以把传过来的name和pwd 放在一个javabean 然后放到request，在传到页面上来
    如果你得到的是一个集合list 可以这样写
    <logic:iterate name="list" id="getlist">
    <tr>
    <TD><bean:write property="name" name="getlist"/></TD>
    <TD><bean:write property="pwd" name="getlist" /></TD></tr>
    </logic:iterate>
