The value for the useBean class attribute com.firm.Firm is invalid
<%@   page   language= "java "   contentType= "text/html;charset=GB2312 "%>
<%@   page   import= "java.sql.* "%>
<%@   page   import= "com.firm.Firm "%>

String   name   =   new   String(request.getParameter( "name ").getBytes( "8859_1 "));
String   emote   =   new   String(request.getParameter( "emote ").getBytes( "8859_1 "));
String   content   =   new   String(request.getParameter( "content ").getBytes( "8859_1 "));
String   strsql   =   "insert   into   guestbook   (name,emote,content)   values   ( ' "   +   name   +   " ', ' "   +   emote   + " ', ' "   +   content   +   " ') ";
addBean.executeUpdate(strsql);
out.print( "您的留言已经保存到数据库中,谢谢! ");
%>
</body>
</html>

老是提示说org.apache.jasper.JasperException:   /ok_guest.jsp(18,0)   The   value   for   the   useBean   class   attribute   com.firm.Firm     is   invalid.

而且Firm.class也是放在   WEB-INF\classes\com\firm   下的

------解决方案--------------------
你引这个类包时能不能改成com.firm.*?

改完了以后试试
