当我启动 Tomcat 8 服务器时出现以下错误。 我正在使用 ojdbc14.jar，我也尝试过使用 ojdbc6.jar，但它不起作用。这只发生在 Tomcat 8 上。如果我使用 Tomcat 7，那么它不会抛出任何异常。 JRE版本为7

最佳答案
在 Java 7 中使用 ojdbc7.jar，它应该可以工作。
关于java - 使用 Tomcat 8 服务器创建与 Oracle9 数据库的连接时出现 AbstractMethodError，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35692822/
