Eclipse RCP 连接到 oracle

Question

我正在尝试在后端使用 Eclipse RCP 和 Oracle 创建简单的数据库应用程序。我将 ojdbc14.jar 保留在 eclipse 的类路径中，当我按它时，它会向我显示该类

Cntr-Shift-T

它显示类路径中存在的类 oracle.jdbc.driver.OracleDriver

但是当我运行程序时，它显示错误消息为

java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver

Where can I put my Jar file so that eclipse RCP can see it?

在 RCP 项目中，您不能直接包含 JAR 文件。一种包含方法是从 JAR 文件创建单独的插件项目，并将新创建的插件作为依赖项包含在内。
