Max length of request parameter

[Scott Duncan]

Anyone know if there is a maximum length of a string value being posted from a form? The thread seems to just freeze when I try to pull this value out of the request in my servlet. Is this container specific? I am using tomcat.

If the request is a POST, there's no max length other than good sense.

If a GET, there is a browser-dependent length that limits the length of the query string.

Bottom line, use POST when appropriate.

You need to look elsewhere for the problem, getting a value from a request should be very quick. Kindly give us more information about the setup you are working with, how the request is generated, what you are doing with the data, etc.

As suggested, if it just hangs when
the form is submitted, check your form method.

The form method is set to POST. The parameter value in question is set as a hidden input in the form. In the servlet:

    
        Enumeration<String> param = request.getParameterNames();
        while (param.hasMoreElements())
        {
            String key = param.nextElement();
            String value = request.getParameter(key);//hangs here
            .....do stuff here
        }
 

Nothing special going on here as far as I know. The only thing that seems out of the ordinary is the value (as seen in the page source) is very long.

Just to add more about the environment.

Using:

Tomcat 5.5
Java 5
Servlets/JSPs - no fancy frameworks
debugging with sysdeo eclipse plugin
