在jsp中使用两个连接对象

时间：2014-12-17 04:40:08

标签： java jsp jdbc

我正在开发一个遗留应用程序，其中jsp文件用于创建和关闭连接，我无权更改或查看连接文件。 一切正常，直到在单个文件中使用多个连接文件，在这种情况下，始终使用在第一个文件中创建的连接对象，并且忽略第二个文件中的连接对象。它给出了SQLCODE = -204错误，该错误是找不到表的。

文件的添加方式如

<%@ include file="connection1.jsp"%>
//Code requiring connection1.jsp goes here
<%@ include file="disconnect1.jsp"%>
<%@ include file="connection2.jsp"%>
//Code requiring connection2.jsp goes here
//The exception with SQLCODE=-204 occurs here
<%@ include file="disconnect2.jsp"%>

我提供完整的错误堆栈跟踪以供参考

1 个答案:

答案 0 :(得分：0)

我之前找到了解决方案，但无法到达此处。 就是这样，标签根据需要进行了修改，连接没有在那里重新初始化，这就是使用相同连接对象的原因。 当它重新初始化时，它起作用了。
