You welcome to use my code... the syntax is not 100% for i changed table names, field names, etc for copyright purposes... but this is how i did mine
You will need to change it according to yur program/output
Create your SQL statement ...
=======================================================================================================
String q8="SELECT *     + "from search_projects "
     + "where queried_user_name = '" + g_user_name + "'";
os.println("<BR><BR><BR>");
DisplayQuery(q8, res, "view");
========================================================================================================
static String DisplayQuery(String p_sql,HttpServletResponse res, String p_heading_types)
throws ServletException,IOException
PrintWriter os=res.getWriter();
Statement stmt = null;
String l_error = "";
try
stmt = con.createStatement();
stmt.execute(p_sql);
ResultSet rs = stmt.getResultSet();
if (rs != null)
DispResultSet(rs, res, p_heading_types);
rs.close();
return(p_sql);
catch (Exception e)
os.println("<BR><BR>EXCEPTION. Unable to execute. If problem persists, please contact");
os.println(e);
return("<BR>ERROR3");
===================================================================================================
static void DispResultSet(ResultSet rs, HttpServletResponse res, String p_heading_types)
throws ServletException,IOException, SQLException
PrintWriter os=res.getWriter();
ResultSetMetaData rsmd = rs.getMetaData ();
int p=0;
int numCols = rsmd.getColumnCount ();
if (p_heading_types.equals("view"))
while (rs.next())
os.println("<TABLE BORDER=1 COLS=" + numCols + ">");
     os.println("<TR>");
     os.println("<TD>");
os.println("<TH><FONT color=blue>Id</FONT></TH>");
os.println("</TD>");
     os.println("<TD>");
os.print("<FONT color=black>"+rs.getString(1)+"</FONT></TD>");
     os.println("</TD>");
     os.println("</TR>");
     os.println("<TR>");
     os.println("<TD>");
os.println("<TH><FONT color=blue>Amount</FONT></TH>");
     os.println("</TD>");
     os.println("<TD>");
os.print("<FONT color=black>"+rs.getString(2)+"</FONT></TD>");
     os.println("</TD>");
     os.println("</TR>");
     os.println("<TR>");
     os.println("<TD>");
os.println("<TH><FONT color=blue>rings</FONT></TH>");
     os.println("</TD>");
     os.println("<TD>");
os.print("<FONT color=black>"+rs.getString(3)+"</FONT></TD>");
     os.println("</TD>");
     os.println("</TR>");
     os.println("<TR>");
     os.println("<TD>");
os.println("<TH><FONT color=blue>Date</FONT></TH>");
     os.println("</TD>");
     os.println("<TD>");
os.print("<FONT color=black>"+rs.getString(4)+"</FONT></TD>");
     os.println("</TD>");
     os.println("</TR>");
     os.println("<TR>");
     os.println("<TD>");
os.println("<TH><FONT color=blue>Email</FONT></TH>");
     os.println("</TD>");
     os.println("<TD>");
os.print("<FONT color=black>"+rs.getString(5)+"</FONT></TD>");
     os.println("</TD>");
     os.println("</TR>");
os.println("</TABLE>");
os.println("<BR><BR><BR>");
p=p+1;
