Were you thinking something like this sample code? Only with an
Array? I already have the List loaded. I would be passing in lat,
lng and a String label in a single geotag object. Not sure if this
helps... I'm still looking for something that fits. Thanks again for
any assistance. John
<html>
<head>
<title>Array Elements</title>
<%@ page import="java.util.*" %>
<%@ page import="java.text.*" %>
<%
Format formatter = new SimpleDateFormat("MMMM");
Calendar calendar = Calendar.getInstance();
String[] monthName = new String[12];
for (int i = 0; i < 12; i++) {
calendar.set(Calendar.MONTH, i);
monthName[i] = formatter.format(calendar.getTime());
}
int month = monthName.length;
%>
</head>
<body>
<script>
var month = new Array(<%=month%>);
<%for (int i = 0; i < month; i++) {%>
month[<%=i%>] = "<%=monthName[i]%>";
<%}%>
document.write("<h2>Elements of the array</h2>");
for( i = 0; i < month.length; i++){
document.write("<b>"+month[i]+"</b><br>");
}
</script>
</body>
</html>
