| Mailing Forms |
A convenient way of gathering form data is simply to mail the form results to a mailbox. Mail is the most effective push technology.
Sending mail with Resin is just like writing to a file. Resin recycles APIs to reduce information pollution. Its VFS (virtual file system) extends and simplifies java.io. Sending mail is just like writing to a file. Resin's Path class is like File and its WriteStream is a combination of OutputStream and PrintWriter.
<%@ page language=java %>
<%@ page import='com.caucho.vfs.*' %>
<%@ page import='java.util.*' %>
<%
Path mail;
mail = Vfs.lookup("mailto:survey?subject='Colors'");
WriteStream os = mail.openWrite();
Enumeration e = request.getParameterNames();
while (e.hasMoreElements()) {
String key = (String) e.nextElement();
String value = request.getParameter(key);
os.println(key + ": " + value);
}
os.close();
%>
