Answer 1

can you connect to the database without the servlet?
put your stuff into this and try it. If it works, add something to check the table names. - %
package test;
import java.sql.Connection;
import java.sql.DatabaseMetaData;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.Statement;
