无论我在哪里指定，Tomcat 7都无法加载ojdbc6.jar

标签： spring tomcat jdbc oracle11g web-deployment-project

这是一个真正考虑我的耐心。我有一个简单的Spring 3.1 + Jersey应用程序，我正在尝试使用ojdbc6.jar作为我的数据源。不幸的是，无论我尝试什么，它都永远找不到“oracle.jdbc.driver.OracleDriver”类。

我打开了类加载器跟踪，我可以看到正在加载的ojdbc6.jar：

我的jdbc.properties文件：

jdbc.driver="oracle.jdbc.driver.OracleDriver"/>
jdbc.url="jdbc:oracle:thin:@10.10.10.10:1522:db"/>
jdbc.user="USER"/>
jdbc.password="password"/>

我已经尝试将它放在WEB-INF / lib目录中以及Tomcat的LIB目录中。两次尝试都失败了。

5 个答案:

答案 0 :(得分：6)

我认为它是一个类加载问题。 我能想到的是：

  • 两个ojdbc.jars在您的类路径中可访问，一个在tomcat / lib中，另一个在WEB-INF / lib中
  • 两个ojdbc.jars在您的类路径中可访问，一个在JRE ext文件夹中，另一个在WEB-INF / lib中

或类似的东西。

确保类路径中只有一个JDBC驱动程序。您可以删除WEB-INF / lib中的那个以查看您的应用程序是否有效。

答案 1 :(得分：4)

oracle.jdbc.driver.OracleDriver类已弃用多年，且为removed from ojdbc6.jar in Oracle JDBC Drivers release 11.1.0.7.0。

您应该使用oracle.jdbc.OracleDriver代替。

答案 2 :(得分：1)

你确定.jar在正确的位置吗？例如，在这种情况下，它需要位于nTomcat“common / lib”，而不是“app / lib”：

答案 3 :(得分：1)

事实证明，经过一夜的休息和一段时间之后，我带领this link here in SO.结果我的jdbc.properties文件对我的Oracle实例构建得很糟糕，但对我的Sybase实例来说却是正确的。感谢大家的帮助。向我投票，因为我很荒谬。

答案 4 :(得分：0)

我正在使用Jetbrains IntelliJ IDE。我选择了设置 - 构建，执行，部署 - 构建工具 - Maven - Runner ，并在JRE ComboBox中选择了高于1.6的Java版本。错误消失了。
