package email;

response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();
String [] musictype = request.getParameterValues("music");
int i;
for ( i = 0; i< musictype.length; i++) {
}
out.println("<html>");
out.println("<head>");
out.println("<title>Servlet DisplayMusicChioces</title>");
out.println("</head>");
out.println("<body>");
out.println("<table style='border:2px solid red'>");
out.println("<tr>");
out.print("<td>");
out.print("<h1>Thank you for joining our email list,</h1>" + firstName + musictype [i]+ lastName);
out.println("</td>");
out.println("</tr>");
out.println("<table>");
out.println("</table>");
out.println("</body>");
out.println("</html>");

Re: hwo to pass values from list box to servlet
Just an idea, I'm not sure if this works with servlets but this is how I've seen it in php ...
Code:
<select name='color[]' size=4 multiple>
<option value='blue'>Blue</option>
<option value='green'>Green</option>
<option value='red'>Red</option>
Notice the brackets in the name of the list: "color[]"
Perhaps the same trick needs to be applied in Java.
Never tried it before, but hey :) at least it's some inspiration for you, in case you're really stuck.
