Hi i was unable to deploy a web-application into tomcat and when i try to start that service in manager it came up with messages which says FAIL - Application at context path /hello could not be started
Here is the source codes
HelloWorldServlet.java

import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.sql.*;

public
    class HelloWorldServlet extends HttpServlet {
    
    public void doGet (HttpServletRequest req, HttpServletResponse res)
	    throws ServletException, IOException {
	    PrintWriter out = null;
	    Connection connection = null;
	    Statement statement;
	    ResultSet rs;
	    try {
		Class.forName("com.mysql.jdbc.Driver");
		connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/IMS","root","");
		statement = connection.createStatement();
		res.setContentType("test/html");
		 out = res.getWriter();
		rs = statement.executeQuery("select * from miriyala");
		out.println("<HTML><HEAD><TITLE>Miriyala</TITLE></HEAD>");
		out.println("<BODY>");
		out.println("<UL>");
		while (rs.next()) {
		    out.println("<LI>" + rs.getString("user_name") + " "
				+ rs.getString("city"));
		}
		
		out.println("</UL>");
		out.println("</BODY></HTML>");
	    } catch (ClassNotFoundException e) {
		out.println("Driver Error");
	    } catch (SQLException e) {
		out.println("SQLException: " + e.getMessage());
	    }
	}
    
}
