Question

我的机器上安装了windows7 64bit。

Oracle 11G客户端（32位）
My eclipse 6.6（322bit）

尝试从我的Java应用程序到Eclipse 11G建立连接时，它会抛出以下错误：

可能是什么问题？

Answer 1

使用Oracle提供的纯Java类型IV JDBC驱动程序。它不应该需要任何本机代码。

我在堆栈跟踪中看到了Tomcat。在启动之前，应该将JDBC驱动程序JAR放在Tomcat / lib文件夹中。

我在堆栈跟踪中看到了一些奇怪的东西：Oracle数据池，思科。我不知道为什么你的部署中有那些。我建议只要使用vanilla JDBC并在工作后进行分支。

如果你甚至不知道JDBC JAR，我会想知道你还不知道还有什么。这次部署可能有问题。

找不到依赖库 - UnsatisfiedLinkError
