from mysql to javascript -


i'm trying draw polyline coordinates mysql through javascript function within jsp file tried code below doesn't work!

<script type="text/javascript" src="http://maps.googleapis.com/maps/api/js?sensor=false"></script> <script type="text/javascript">   function initialisation(){     var centrecarte = new google.maps.latlng( 47.381381, 0.687503 );     var optionscarte = {       zoom: 12,       center: centrecarte,       maptypeid: google.maps.maptypeid.roadmap     }      class.forname("com.mysql.jdbc.driver");      connection conn = null;     statement state = null;     resultset resul= null;      conn = drivermanager.getconnection("jdbc:mysql://localhost:3306/new","root","pass");     state=connection.createstatement();     string sql ="select lat, lng route ";      result = statement.executequery(sql);     while(result.next()){       s1= result.getfloat(lat);       s2= result.getfloat(lng);        var macarte = new google.maps.map( document.getelementbyid( "emplacementdemacarte" ), optionscarte );       var tableaupointspolyline = [         new google.maps.latlng("+s1+ ","+s2+")       ];       var optionspolyline = {         map: macarte,         path: tableaupointspolyline       };       var mapolyline = new google.maps.polyline( optionspolyline );     }     google.maps.event.adddomlistener( window, 'load', initialisation );   } </script>

what needed fix problem listed?

stop trying random code! also, don't confuse java , javascript. code posted using scriptlets , missed <% %> symbols, 

<% class.forname("com.mysql.jdbc.driver");  connection conn = null; statement state = null; resultset resul= null;  // have mysql on localhost listening 3306. there new db? root's  // password pass? conn = drivermanager.getconnection("jdbc:mysql://localhost:3306/new","root","pass"); state=connection.createstatement(); string sql ="select lat, lng route ";  result = statement.executequery(sql); while(result.next()){   %>   s1=<%= result.getfloat(lat) %>;   s2=<%= result.getfloat(lng) %>; <% } %>

note shouldn't using model 1 in 2014 (mixing java in general, jdbc code, in jsp asking trouble).
