Re: Maximum size of file uploads?

[Ramesh, Kesav]

hey we have a separate application using oreilly's class but care should be
taken that when you are uploading the files you are going to send  that uch
thru the req object. it works well for size <10 mb.see oreilly for much
details about this class

/**
 * A utility class to handle <tt>multipart/form-data</tt> requests,
 * the kind of requests that support file uploads.  This class can
 * receive arbitrarily large files (up to an artificial limit you can set),
 * and fairly efficiently too.
 * It cannot handle nested data (multipart content within multipart content)
 * or internationalized content (such as non Latin-1 filenames).
 * <p>
 * It's used like this:
 * <blockquote><pre>
 * MultipartRequest multi = new MultipartRequest(req, ".");
 * &nbsp;
 * out.println("Params:");
 * Enumeration params = multi.getParameterNames();
 * while (params.hasMoreElements()) {
 *   String name = (String)params.nextElement();
 *   String value = multi.getParameter(name);
 *   out.println(name + " = " + value);
 * }
 * out.println();
 * &nbsp;
 * out.println("Files:");
 * Enumeration files = multi.getFileNames();
 * while (files.hasMoreElements()) {
 *   String name = (String)files.nextElement();
 *   String filename = multi.getFilesystemName(name);
 *   String type = multi.getContentType(name);
 *   File f = multi.getFile(name);
 *   out.println("name: " + name);
 *   out.println("filename: " + filename);
 *   out.println("type: " + type);
 *   if (f != null) {
 *     out.println("f.toString(): " + f.toString());
 *     out.println("f.getName(): " + f.getName());
 *     out.println("f.exists(): " + f.exists());
 *     out.println("f.length(): " + f.length());
 *     out.println();
 *   }
 * }
 * </pre></blockquote>
 *
 * A client can upload files using an HTML form with the following
structure.
 * Note that not all browsers support file uploads.
 * <blockquote><pre>
 * &lt;FORM ACTION="/servlet/Handler" METHOD=POST
 *          ENCTYPE="multipart/form-data"&gt;
 * What is your name? &lt;INPUT TYPE=TEXT NAME=submitter&gt; &lt;BR&gt;
 * Which file to upload? &lt;INPUT TYPE=FILE NAME=file&gt; &lt;BR&gt;
 * &lt;INPUT TYPE=SUBMIT&GT;
 * &lt;/FORM&gt;
 * </pre></blockquote>
 *

Subject: Maximum size of file uploads?


Hi,

Does anybody know whether it is possible to limit maximum size of file
upload in Tomcat. At the moment, if I try to upload file larger than 1MB the
server gives me an error  "Cannot find server or DNS Error". On what this
size is dependent on?

Thanks,

Risto
