[Harshal Gurav]

Hi

i am getting error as class not found exception : com.mysql.jdbc.driver . my project folder already consist of mysql .jar file in /web appls/web-inf folder.
Application is running successfully in other machine from where i took the application file. As this error appeared I also added jar file into project path as Project ---->properties-- build java path---libraries----add external jar file.

You might have better luck with this question in the IDEs forum because Eclipse sometimes does strange things when deploying web applications. I'll move it for you.

By the way, the JDBC JAR file should be in WEB-INF/lib (though that sometimes depends on the app server you are using, you should let us know which app server you have).

Please make sure to capitalize things properly, like WEB-INF and Driver, as these things are different, and significant.

This reply is wrt the error: class not found exception : com.mysql.jdbc.driver in eclipse Tool in a Dynamic Web App.( Tomcat Server)

I faced the same and figured that apart from adding the mysqlconnector jar to the class buildpath(Project->Properties->Java Build Path->Add External Jar), you need to copy paste the jar in the WEBINF folder of your project as well.
Ideally, restart IDE after this.

Hope this helped.

Welcome to the Ranch.

I take it you are using Eclipse.

Not really. As Peter mentioned, it should be under WEB-INF/lib. Once you put it there, its an "internal" jar! No restart required.
