奋斗 - 类未找到异常：com.mysql.jdbc.Driver在JAVA中 [英] Struggling with - Class not found exception: com.mysql.jdbc.Driver in JAVA

问题描述

在Netbeans ide 7.0中，我面临这个特殊的问题。我在我的程序中写了以下代码行。

In Netbeans ide 7.0, I am facing this particular problem. I wrote the following line of code in my program

Class.forName（com.mysql.jdbc.Driver）。newInstance（）;

Class.forName("com.mysql.jdbc.Driver").newInstance();

这一行正在抛出异常。当我从netbeans 7.0中的服务 - >数据库 - >驱动程序 - > MySQL（Connector / Jdriver）连接同一个mysql数据库服务器时，它已经连接。当我进入该连接的属性，我发现它是连接mysql服务器使用相同的类，我在代码行。

This particular line is throwing an exception. And when I connected the same mysql db server from the "Services -> Databases -> Drivers -> MySQL(Connector/Jdriver)" in the netbeans 7.0, it got connected. When I went into the properties of that connection I found that it is connecting the mysql server using the same class which I used in the line of code.

我也读了一些的论坛，例如

I also read some of the forums such as

但是这1是Ubuntu上的netbeans。 Windows

but this 1 is for netbeans on Ubuntu. What about Windows?

I don't know what is wrong? Please help.
