<p><font face="Verdana, Arial, Helvetica, sans-serif"><font size="-1"><b>UploadBean </b>is a JavaBean (JAVA component) that allows to upload files in store. This store could be a folder, a ZIP archive, a database or memory. This document is a guide for developers. We assume that developers have a few JavaBeans and JSP skills and they know what "scope" (page, session, application) is for JavaBeans. <br>
First of all, you need to select a store model : [<a href="developerguide.html#folder">Folder</a>] [<a href="developerguide.html#zip">ZIP Archive</a>] [<a href="developerguide.html#database">Database</a>] [<a href="developerguide.html#memory">Memory</a>]. Once selected, you could switch to another model through [<a href="developerguide.html#setstoremodel">setStoreModel</a>] method. Second, you can add some restrictions on uploaded files like a [<a href="developerguide.html#blacklist">blacklist</a>] or </font><font size="-1" face="Verdana, Arial, Helvetica, sans-serif">a [<a href="developerguide.html#whitelist">whitelist</a>]</font><font size="-1">, a [<a href="developerguide.html#limit">file size limit</a>] and a [<a href="developerguide.html#max">maximum</a>] store size. To store uploaded files, you have to call [<a href="developerguide.html#storecall">store</a>] method with a [<a href="developerguide.html#mp">MultipartFormDataRequest</a>] object </font><font size="-1" face="Verdana, Arial, Helvetica, sans-serif">(see [<a href="developerguide.html#overwrite">overwrite</a>] options for duplicate entries)</font><font size="-1">. Finally, you can [<a href="developerguide.html#clean">reset</a>] store if needed. Any object implementing [<a href="developerguide.html#listener">UploadListener</a>] interface could be notified when an uploaded file is stored. Note that an [<a href="developerguide.html#history">history</a>] of uploaded parameters (files without binary data) is available. Finally, UploadBean supports three multipart parsers. You could select one through [<a href="developerguide.html#parser">parser</a>] property.<br>
