你有幾個這樣的電話。getDate（index）'，則錯誤消息會通知您某些或所有行中列（8和9）中的值不能表示爲「java.sql.Date」對象。 – Titus

此外，看起來像那些日期值根據錯誤消息是空的'值''不能表示爲java.sql.Date' –

你可以粘貼employee_details表的結構嗎？ – ProgrammerBoy

<c:if test="${not empty rs.getDate(8)}"> out.println("<td style='text-align:center; border: solid 1px #000; border-top:none; border-right:none; width:125px''>"+rs.getDate(8)+"</td>"); </c:if>

這裏是我觀察到的一些事情。

看看你employee_data.jsp的rs.getXXX()。你沒有按照訂單。對於select * from employee_details，當調用rs.getXXX()時，應使用resultset的正確方法。如果你看看你的桌子，你只有9日和10日，所以rs.getDate(8)是不正確的。使用rs.getDate()只有第9和第11欄即rs.getDate(9)和rs.getDate(11)

out.println("<td style='text-align:center; border: solid 1px #000; border-top:none; border-right:none; width:125px''>"+rs.getDate(8)+"</td>"); //??? 
    out.println("<td style='text-align:center; border: solid 1px #000; border-top:none; border-right:none; width:100px''>"+rs.getString(7)+"</td>"); //?? 
    out.println("<td style='text-align:center; border: solid 1px #000; border-top:none; border-right:none; width:100px''>"+rs.getDate(9)+"</td>"); 
    out.println("<td style='text-align:center; border: solid 1px #000; border-top:none; border-right:none; width:100px''>"+rs.getString(10)+"</td>"); 
    out.println("<td style='text-align:center; border: solid 1px #000; border-top:none; border-right:none; width:100px''>"+rs.getString(11)+"</td>"); 
    out.println("<td style='text-align:center; border: solid 1px #000; border-top:none; width:100px''>"+rs.getString(11)+"</td>"); //????

不要使用select *。其一種不好的做法。將來如果您的employee_details有更多的列，那麼您需要更改代碼以適應這些新列。使用select EmployeeID,Password,<otherfield> from employee_details。
使用rs.getXXX(index)中的索引時要小心。它可能會導致錯誤。相反，您可以使用rs.getXXX(columnnameintbl)。例如，您可以使用rs.getString("EmployeeID")而不是rs.getString(1)。

希望這有助於！
