How to install JDBC driver in Eclipse web project without facing java.lang.ClassNotFoundexception

by

As for every “3rd-party” library in flavor of a JAR file which is to be used by the webapp, just copy/drop the physical JAR file in webapp’s /WEB-INF/lib. It will then be available in webapp’s default classpath. Also, Eclipse is smart enough to notice that. No need to hassle with buildpath. However, make sure to remove all unnecessary references you added before, else it might collide.

An alternative is to install it in the server itself by dropping the physical JAR file in server’s own /lib folder. This is required when you’re using server-provided JDBC connection pool data source which in turn needs the MySQL JDBC driver.
