java - Connect to a MySQL DB with JSP through another class -

Can I connect to a MySQL db with JSP through another class?

Here's my own suggestion: ... & Lt;% // JSP / Java Codes UsersDAPInterface users = new UserDAPClass (); // This includes MySQL connections in Java class etc.% & Gt; & Lt; / Body & gt; ...

When I do this, I get a lot of errors and exceptions, in which ClassNotFound , NullPointer etc.

I also found:

  java.lang.ClassNotFoundException: com.mysql.jdbc.Driver   
 Which means it It should be that there is no MySQL driver in it. But I have imported the mysql driver, so I do not know that it should usually be imported in any other way. any suggestion?   
 
 
 Ensure that  WEB-INF / lib  is the folder of your application , As long as there exists, this problem should not come up.
