[xwiki-devs] Integrating Java Swing components with Xwiki

Hello Devs, This is regarding the capability to upload Multiple files at a time to Xwiki. I understand that currently the attach functionality is rendered using HTML. The HTML file upload control does not allow mutliple files to be selected/uploaded at one time. Hence, I looked the JFileChooser component of Java Swing. I can write a Class that brings up a JFileChooser object and allow multiple selections at once. But, I am not sure how to integrate this functionality with Xwiki , especially with the Velocity templates (which are used to render the pages). Few Questions: 1) in order to achieve this, do I need to create a velocity template that will render the fileChooser on the XWiki page ? 2) If yes, how do I accomplish this? create a new "action" and then write the render and action methods for that? 3) If no, what are my other options to achieve this? Please guide me. Thanks
