Editing Wiki From Eclipse

Plog4u instructions for all OS

Close Eclipse
Download the Plog4u plugin from here
Unzip it in your eclipse root directory
Copy {eclipse root dir}/plugins/org.plog4u.wiki_2.0.6/wikis/Plog4UORG.properties to JajukWiki.properties and change BaseURL (first line) to:

baseURL=http://wiki.jajuk.info

Edit {eclipse root dir}/plugins/org.plog4u.wiki_2.0.6/plugin.xml and in the section

<extension point="org.plog4u.wiki.favorites">

add

<favorite id="org.plog4u.wiki.favorite.eclipse" name="JajukWiki"/>

Start Eclipse, possibly using the eclipse -clean command
In Eclipse: Window->Preferences->Wikipedia Editor configuration, add this two new items:

Name="Load Jajuk" 
user=<your wiki login> 
pwd=<your wiki password> 
URL="http://wiki.jajuk.info/index.php/Special:Export" 
Type="Load JajukWiki"

Name="Store Jajuk" 
user=<your wiki login> 
pwd=<your wiki password> 
URL="http://wiki.jajuk.info/index.php" 
Type="Store JajukWiki"

Follow instructions from here to upload or download pages. (You will have to create a new Wikipedia Project and then an empty file index.wp containing wiki links, have a try with the example it is a good start, then have a go with categories).
To export pages to HTML or PDF: select items or the entire project -> Export -> Others -> Wikipedia to HTML (or PDF)

Note: I didn't manage to make it work behind a corporate proxy
