Hi all!
I am trying to connect to JDBC in a servlet, the html page gets displayed
the try statement and i find that the connection is not made. I am using
tomact 4.0.4 and have deployed the class file in
\webapps\ROOT\WEB-INF\classes directory. Can anyone please suggest a path
forward? In case i need to map the servlet in web.xml, i don't know how to !
Thanks in advance!

my code:
public class Servlet_JDBC extends HttpServlet{
Connection conn;
private ServletConfig config;
public void init(ServletConfig config)
throws ServletException{
this.config=config;
}
public void service (HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
HttpSession session = req.getSession(true);
res.setContentType("text/html");
PrintWriter out = res.getWriter();
out.println("<HTML><HEAD><TITLE>Query Results</TITLE>");
out.println("</HEAD>");
out.println("<BODY bgColor=blanchedalmond text=#008000 topMargin=0>");
out.println("<P align=center><FONT face=Helvetica><FONT
color=fuchsia style=\"BACKGROUND COLOR
:white\"><BIG><BIG>List</BIG></BIG></FONT></P>");
out.println("<P align=center>");
out.println("<TABLE align=center border=1 cellPadding=1
cellSpacing=1 width=\"75%\">");
out.println("<TR>");
out.println("<TD>PARAMETER</TD>");
out.println("<TD>VALUE</TD>");
out.println("</TR>");
try{
Class.forName("org.gjt.mm.mysql.Driver");
conn =
DriverManager.getConnection("jdbc:mysql://databaseURL/dataBaseName",
"userName", "password");
Statement stmt=conn.createStatement();
ResultSet rs=stmt.executeQuery("SELECT PARAMETER, VALUE FROM
MYTABLE");
while(rs.next()){
out.println("<TR>");
out.println("<TD>" + rs.getString(1) + "</TD>");
out.println("<TD>" + rs.getString(2) + "</TD>");
out.println("</TR>");
}
rs.close();stmt.close();conn.close();
}catch(Exception e){out.println(e.getMessage());}
out.println("</TABLE></P>");
out.println("<P> </P></FONT></BODY></HTML>");
}
public void destroy(){}
}
