One, the original is Tomcat can not find the MySQL jar package!

Mysql-connector-java-5.1.7-bin.jar must be imported into Tomcat's lib directory!

In a Java project, you just need to introduce Mysql-connector-java-5.1.7-bin.jar to run a Java project.

In a Web project, when Class.forName ("Om.mysql.jdbc.Driver"), MyEclipse is not going to find the string and will not look for the driver. So you just need to copy the Mysql-connector-java-5.1.7-bin.jar to Tomcat under the Lib directory.

Second, Eclipse generates the WebContent directory by default, MyEclipse generates Webroot.

settings when creating a new project:

In the New dialog box, next, change the name of the Content Directory to Webroot when you go to the Web Module, and tick the create XML at the bottom
