我想这么做,但是总报错,请问为什么 关于 javabean

只看 
public String decodeChar(String myString)和
<%
temp= rs.getString("title");
// *****************************  问题所在
temp=listMessage.decodeChar(temp);  //报错 
//  temp = new String(temp.getBytes("GBK"),"ISO8859_1"); 
out.println(temp);
%>这两部分就可以了.别的地方应该没问题 高手帮忙

    你试着在jsp加判断看看，
    <%
    temp= rs.getString("title");
    if(temp == null || temp.equals("")
    {
          temp=listMessage.decodeChar(temp);  
    //  temp = new String(temp.getBytes("GBK"),"ISO8859_1"); 
    out.println(temp);
    }
    %>
    其他的应该没问题啊。
