Backport of Import Export Script

Hi All. This is probably most appropriate to Jeremi, but I would appreciate anyones thoughts on the subject. XWiki is a phenomenal piece of software that I am thinking of new uses every day. I am currently running 0.9.840 on one of my servers and am a little bit paranoid about upgrading until later in the year, as our application is growing at a furious rate and I would like it to stabilise a little before we go through an upgrade. However, some of the new features are very tempting (I am using the standalone for testing). Ideally I would like to use your XWiki/ImportExport script to create user configurable exports on the existing data and was wondering how involved the underlying adjustments would be to the code to make it work with the stable version. The script looks for $export. Is this a java class that is put into a xwiki context in the later release? If so, is it self sufficient enough to compile and add to an existing installation, or is it too dependent on other code in the later version? With custom java classes, is there a straight forward description somewhere on putting them in an XWiki context so they can be used by Velocity? In a mildly related point: I have deployed DWR (https:// dwr.dev.java.net/) side by xwiki in another testing installation for some AJAX experimentation and it seems to be co-habiting without too much trouble. Apologies for the basic questions, but I am currently on a steep learning curve with this and appreciate any help offerred. Have a great day. Mark.
