org.apache.jasper.JasperException 错误

Question

我收到以下错误。

• 我正在使用 MyEclipse Bling 10.1
• 部署在 Tomcat 上
• MS SQL 2008 R2

当我在 MS SQL 2000 中执行相同操作时，代码可以正常工作。我想找到我做错的地方。

    HTTP Status 500 -

尝试谷歌搜索根本原因通常是个好主意。在这种情况下“指定的 DSN 包含驱动程序和应用程序之间的体系结构不匹配”，第一个结果给你答案：http://msdn.microsoft.com/en-us/library/windows/desktop/ms712362%28v=vs.85%29.aspx

检查你的jsp语法。它可能不会在 eclipse 中显示任何错误，但手动检查它是否存在任何丢失的括号或 jsp 语法中的任何错误导致此问题
