Tomcat 7无法加载ojdbc6.jar无论我在哪里指定

这是一个真正尝试我的耐心。我有一个简单的Spring 3.1 + Jersey应用程序，我试图使用ojdbc6.jar作为我的数据源。不幸的是，无论我尝试什么，它都找不到“oracle.jdbc.driver.OracleDriver”类。Tomcat 7无法加载ojdbc6.jar无论我在哪里指定

我已经打开的类加载器跟踪，我可以看到正在加载的ojdbc6.jar：

我试过把它放在WEB-INF/lib目录下和Tomcat的LIB目录中。两次尝试都失败了。

你的ojdbc.jar在哪里？在你的Tomcat中是否有多个（tomcat \ lib中的一个和WEB-INF \ lib中的另一个）？ –

在任何时候，有没有使用2个相同的罐子。我只是写了那个来显示我在哪里放置了JAR文件进行测试。 – Carlos

原来，经过好一个晚上的休息和一段时间之后，我带领我到了this link here in SO.原来我的jdbc.properties文件是针对我的Oracle实例构造的很糟糕，但是对于我的Sybase实例来说却是非常糟糕的。感谢大家的帮助。因为荒唐而投我的票。

你确定.jar是否在正确的位置？例如，在这种情况下，它需要将位于我nTomcat “common/lib目录”，而不是 “应用程序/ lib目录”：

我很惊讶你没有看到我的信息。这是Tomcat 7，如果你明白这一点，你会知道lib目录已经崩溃了。请参阅'http：// tomcat.apache.org/migration.html'。如果我正在运行Spring 1.2.6，那么这个话题是从2005年开始的，这很方便。 – Carlos

的oracle.jdbc.driver.OracleDriver类已被废弃多年，是removed from ojdbc6.jar in Oracle JDBC Drivers release 11.1.0.7.0。

您应该改用oracle.jdbc.OracleDriver。

这里是我的”我做了：我拿了11.2.0.2 JAR并通过7zip检查。检查出好。看着文件结构，它都是正确的。课程是他们应该在的地方。我在这个Web应用程序的外部编写了一个小型Java应用程序，它编译得很好。我使用完全不同的JAR（Sybase）来隔离我的应用程序和JAR工作。在这一点上，我继续前进，然后使用我的ORACLE JAR文件，然后继续失败。然后，我下载了11.2.0.3并执行了相同的步骤，但也失败了。 – Carlos

哦，然后，我将应用程序部署到：Glassfish 3 +，Oracle WebLogic 11g和WebSphere 8.0.0.5，并且它们都失败并出现SAME错误。这有帮助吗？ – Carlos

我相信它是一个类加载问题。 我能想到的事情是：

  • 两个ojdbc.jars在访问你的classpath，一个在Tomcat中/ lib下，另一个在WEB-INF/lib目录
  • 两人在访问ojdbc.jars在类路径，一个在JRE ext文件夹中，另一个在WEB-INF/lib中

或类似的东西。

只要确保类路径中只有一个JDBC驱动程序。您可以删除WEB-INF/lib中的一个，以查看您的应用程序是否可用。

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。
