JAXB @XmlAnyElement example

Monday, June 7th, 2010

The problem

I was recently working on a JAXB centric app which was required to capture “arbitary” xml. e.g.

<a>
   <b></b>
   <c></c>
   <d>
       <!-- "Unknown" XML here -->
       <maybee></maybee>
       <maybef></maybef>
       <!-- etc etc -->
   <d />
</d></a>

How could I ever capture the contents of if they could be “anything”?
(more...)

Reset Gnome desktop the easy way

Sunday, May 16th, 2010

I recently upgraded Ubuntu on one of machines from 9.10 (Karmic Koala) to 10.04 (Lucid Lynx). In the old version I had installed a lot of widgets, messed up the fonts, buttons – loads of things. I needed an easy way to restore/reset the Gnome desktop back to the default look and feel.

I could of course have used the gui’s to undo all the changes I made but why bother? This is Linux after all!

# cd
# [sudo] rm -rf .gnome .gnome2 .gconf .gconfd .metacity
