关于mutlibox与LabelValueBean的问题

qw3q2w21 2008-05-21 12:07:33

想做一个复选框的提交页面
我用的是struts1.x框架
form文件
private LabelValueBean[] mstra;//setter getter

jsp文件
<%

UserUtil mm = new UserUtil();
LabelValueBean[] ms = mm.getmstr();
session.setAttribute( "ms", ms);
%>

<td>
<logic:iterate id = "mstra" name= "ms">
<html:multibox name = "mstra" property="value">
<bean:write name = "mstra" property="value"/>
</html:multibox >
<bean:write name = "mstra" property="label"/>
</logic:iterate >
</td>

getmstr()方法是UserUtil 中的提取数据库数据的
public LabelValueBean[] getmstr() throws Exception{
LabelValueBean[] mstra1 = new LabelValueBean[20];
DBConnect conn = new DBConnect();
String key = null;
String value = null;
String mslist = "select MID,MName from ADMIN_MODULE";
conn.getConn();
ResultSet rs1 = conn.getrs(mslist);
int i =0;
try{
while(rs1.next()){
key = Integer.toString(rs1.getInt("MID"));
value = (String)rs1.getString("MName");
mstra1[i++] = new LabelValueBean(key,value);
}
}catch(SQLException e) {
System.out.print("Exception in getmid() error!");
}finally {
conn.close();
}
return mstra1;
}

执行页面时提示
org.apache.jasper.JasperException: Unable to compile class for JSP:

An error occurred at line: 16 in the jsp file: /sysmanage/NewRole.jsp
The method getmstr() is undefined for the type UserUtil
13: UserUtil mm = new UserUtil();
14: //mMap = mm.getModulemap();
15: //session.setAttribute( "mMap", mMap);
16: LabelValueBean[] ms = mm.getmstr();
17: session.setAttribute( "ms", ms);
18: %>
