insert into Customer Values("+getName()+","+getAnonymous()+","+getCode()+","+ getEmail()+","+getNumber()+","+getDescription()+")"
错误我没注意看是什么，但是sql语言插入的，如果你的类型是varchar的话，上面的语句最好写成
insert into Customer Values('"+getName()+"'.....
就是varchar的要用‘’引号包起来

String inSertCommand="insert into Customer Values("+getName()+","+getAnonymous()+","+getCode()+","+ getEmail()+","+getNumber()+","+getDescription()+")";
getName()怎么没有对象啊.你从那里GET出来.
registerbeam.setCode(Integer.parseInt(code));
你看看是不code里面没有值或为NULL或不是数字.Top
4 楼muyufeng（）回复于 2005-04-03 15:33:52 得分 0
如果你有一个名称为theName的变量.也要有一对和其对应的get,set 方法.
而且写法上是一定的规范的就是,get +变量名(第一个字母改成大写),如getTheName,setTheName,
如你程序中的getName()方法,要有一个和其对应的name变量.Top
