Java 在两个链接表（通过fk链接）的第二个表中创建行不起作用

我正在使用EclipseJuno、GWT、java和MySQL

我正在将行写入通过fk链接的两个表。对第一个表的写入工作正常。然后，我将此写入的密钥（使用语句返回生成的密钥）返回到下一次写入。执行此写操作时，我收到一个错误“java.sql.SQLException:没有为参数1指定值”。我已经显示了传递给每个参数的值，并且有值

两个表中的第一列都是自动递增主键。第二个表中的第二列是fk

控制台为（显示的前五行是传递给参数的值，第一行是fk）：

发展模式是：

13:16:16.910 [WARN] [org.AwardTracker.AwardTracker] Something other than an int was returned from JSNI method '@com.google.gwt.dom.client.DOMImplIE9::getBoundingClientRectTop(Lcom/google/gwt/dom/client/Element;)': Rounding double (216.00999450683594) to int for int

相关服务器端代码为：

表格如下：

我将感谢任何帮助。关于这一点，Glyn

ps

应该是

ps2

ps2.setInt（1，cd_id）；
ps2.固定管柱（第2节）；
ps2.固定管柱（3，组件）；
setDate（4，（java.sql.Date）startDate）；
setDate（5，（java.sql.Date）endDate）；

谢谢彼得，我为这样一个愚蠢的错误浪费了大家的时间而道歉，也衷心感谢你的帮助。你好，格林。
