Question

我正在尝试在我的本地tomcat服务器中部署基于Spring的Web应用程序。以下是我的申请详情：

基于Spring的Web应用程序（战争）
Tomcat 6服务器
Java 1.6
Oracle DB
以下是jdbc配置：

仅配置tomcat设置。 javax.persistence.jdbc.drive=oracle.jdbc.OracleDriver javax.persistence.jdbc.url=jdbc:oracle:thin:@coursesdev.cvbaybp20ew7.eu-west-1.rds.amazonaws.com:1521:DEVCRS javax.persistence.jdbc.user=test javax.persistence.jdbc.password=test
我还在我的/ lib文件夹中添加了ojdbc6.jar，ojdbc14.jar

我没有任何问题部署了我的war文件。但是当我的应用程序尝试连接到db时，它会抛出错误：“ java.sql.SQLException：没有为jdbc找到合适的驱动程序：oracle：thin：@ coursesdev.cvbaybp20ew7.eu-west ”

我看过很多关于类似问题的帖子，但我不确定我错过了什么。

此错误取决于您的建筑结构。将jar文件添加到您的lib文件夹不会做任何事情。您应该将jar文件添加到类路径中。如果您正在通过IDE构建项目，请说eclipse，您应该将其添加到.classpath文件中。如果您使用的是Idea，则应将其添加到.iml文件等。如果要使用ant构建项目，则应将jar地址添加到build.xml文件中。我想你不是在使用maven。

java.sql.SQLException：找不到合适的驱动程序jdbc：oracle：thin
