employee是空的，下面这句话出现空指针异常
<TD colSpan=4>
<INPUT style="WIDTH: 110px" name="employeeid" id="employeeid"
value="<%=employee.getEmployeeID()%>" readOnly="true">
</TD>
怎么改
加个if判断
判断employee是否为空
{
value=" " readOnly="true">
}
else
{
value="<%=employee.getEmployeeID()%>" readOnly="true">
}
既然知道employee是空的,接下来你就需要往前推 看给employee赋值的地方有没有问题!
employee本来就是null，
employee.getEmployeeID()就是null.getEmployeeID()；
肯定空指针的啊！
非要写的话 给他一个 当employee为空的默认值(0),可以这样
<TD colSpan=4>
<INPUT style="WIDTH: 110px" name="employeeid" id="employeeid"
value="<%=employee!=null?employee.getEmployeeID():0%>" readOnly="true">
</TD>
在你知道 已经知道employee 为空可以叫他不显示,即不为空时再显示
<% if(employee!=){%>
<INPUT style="WIDTH: 110px" name="employeeid" id="employeeid"
value="<%=employee.getEmployeeID()%>" readOnly="true">
<%}%>
