uk.co.weft.maybeupload.MaybeUploadRequestWrapper
A wrapper around a ServletRequest, which knows how to handle multipart/form-data requests gracefully. Implemented as a wrapper not as a specialisation since ServletRequest is an interface. Kludgy. This is where multiple inheritance would be a win.
Note that while this class is written to the Servlet 2.2 spec, it should be extremely easy to convert it to earlier versions of the Servlet API because it's mostly just a wrapper; the only methods that actually do anything are at the top and don't depend on any Servlet 2.2 features.
extends Hashtable
so as to make it implements the
Map interface. In my opinion, there should be a common API to all
the things in Servlets which are essentially namespaces, and the
Map interface is the obvious one.
This class was written having studied the example code in Jason Hunter's book, Java Servlet Programming (which we recommend). It does not, however, use any material from versions of Jason Hunter's code released since the book was published, as these are released under a very peculiar licence which is not compatible with the BSD licence we use.
$Log: MaybeUploadRequestWrapper.java,v $ Revision 1.11 2002/10/08 09:22:48 simon A number of minor enhancements and some bug fixes proposed by Shawn Grunberger Revision 1.10 2001/07/17 13:01:25 simon Added no-args constructor, to ease subclassing. Revision 1.9 2001/04/24 15:55:57 simon Patch release incorporating Aaron Dunlop's ByteArrayInputStream stuff. Revision 1.8 2001/04/09 11:24:24 simon Made maxUpload a configurable parameter ('max_upload') Revision 1.7 2001/03/02 23:25:02 simon getParameter() and getParameterValues() undeprecated, as Berin Loritschpointed out they're part of the Servlet 2.2 spec and as such ought not to be. Revision 1.6 2001/01/23 19:12:17 simon A number of bugfixes, plus an important new feature: you can decide whether to allow name collisions in the upload directory to result in overwriting, renaming of the new file, or an exception. Revision 1.5 2001/01/22 15:11:00 simon changed constructor argument for workdir from file name to file object. Revision 1.4 2001/01/20 14:50:02 simon fixed but: if not multipart and no values for a given name that was asked for, threw a NullPointerException. Fixed. Revision 1.3 2001/01/09 12:14:12 simon Now tested with: Netscape Communicator 4.76/Linux 2.2 Konqueror 1.9.8/Linux 2.2 Microsoft Internet Explorer 5.00.2014.0216IC File upload (including binary file upload) works. Remaining known bug: all fields must have data... Revision 1.2 2001/01/08 12:39:43 simon Now working; still tidying up. Revision 1.1.1.1 2001/01/05 14:58:09 simon First cut - not yet tested

Attributes can be set two ways. The servlet container may set
attributes to make available custom information about a request.
For example, for requests made using HTTPS, the attribute

can be used to
retrieve information on the certificate of the client. Attributes
can also be set programatically using
ServletRequest.setAttribute(java.lang.String, java.lang.Object)

embedded into a request before a RequestDispatcher
call.

names. This specification reserves names matching java.*

object can be used to forward
a request to the resource or to include the resource in a response.

outside the current servlet context. If the path begins with
a "/" it is interpreted as relative to the current context root.
This method returns null
