in my servlet there is a database connection.
if i put mysql connector.jar file to the lib folder in web.INF derectory then it is working.
but if i set the buildPath to the mysql connector using configureBuildPath it says class NotFound error?

That means class path is not set properly. BTW when you face this error compile time or run time?

Hi,

That will not happen Put your mySql connection jar to your lib folder of web inf will automatically add to your build path.

Or if it will not add just right click on jar and select add to build path.



Thanks, Nishan Patel

Which context are you setting these? In IDE?

Hi there!

In Eclipse: Window > Preferences > Java > Build Path > Classpath Variables > New (or edit if you have one)

But does your classes see that class? If you import com.mysql.jdbc.Driver an error is displayed or something like that?

Ok, that seems to be that you don't have that librarie included in your project, you have to add it and the problem is gone.
