代码
我的代码
<%
String wuliao=request.getParameter( "textfield ");
String pinming=request.getParameter( "textfield2 ");
String shulian=request.getParameter( "textfield3 ");
String danjia=request.getParameter( "textfield5 ");
String jine=request.getParameter( "textfield6 ");
String jiaoqi=request.getParameter( "textfield4 ");
String gongyinshang=request.getParameter( "textfield7 ");
String sql= "insert into wuliao(wuliao,pinming,shulian,danjia,jine,jiaoqi,gongyinshang) values( "+wuliao+ ", ' "+pinming+ ", ' "+shulian+ ", ' "+danjia+ ", ' "+jine+ ", ' "+jiaoqi+ ", ' "+gongyinshang+ " ') ";
int result=0;
result=connBean.executeUpdate(sql);
if (result!=0){
out.println( " <script language= 'javascript '> alert( '写入成功! ');window.location.href= 'index.jsp '; </script> ");
}else{
out.println( " <script language= 'javascript '> alert( '写入失败! ');window.location.href= 'Topic_add.jsp '; </script> ");
out.print(wuliao+pinming+shulian+danjia+jine+jiaoqi+gongyinshang);
%>

------解决方案--------------------connBean.executeUpdate
这个connBean应该是你用类文件了
你什么都不放,只放这个
<jsp:useBean id= "connBean " scope= "page " class= "这里是你的类 " />
你只放这一句看好不好使!
------解决方案--------------------看上去是源代码某个地方语法错误
引号可能是错误来源
