Yes there is a limit on the amount of data you can send with GET, but the
problem doesn't appear to be between GET and POST. If he's getting 30 parameter
names I would guess that he's well over the GET limit and so is probably using
POST.
My guess would be that the HTML form is using the same name for some parameters.
For example if the HTML form as a SELECT tag, there will be only 1 parameter
name but many parameter values (if the SELECT is MULTIPLE).
Darko, try the following:
Enumeration enum = req.getParameterNames();
while (enum.hasMoreElements()) {
String name = (String) enum.nextElement();
String[] values = req.getParameterValues(name);
for (int i = 0; i < values.length; i++) {
System.out.println("name: " + name + " value: " + values[i]);
}
}
