Associating *.theme and *.xsp-config with Eclipse XML Editor
When you do XPages OSGi Library development in eclipse, you will often have to edit xml files (or xhtml) that have a different file extension than .xml
These are files such as XPages theme files with the .theme extension, and Xsp control configuration files with the .xsp-config extension.
Unfortunately these file extensions are not associated with the XML Editor by default and this causes undesirable behaviour when you double-click them to open them for editing.
When you attempt to open a .theme file, Eclipse thinks you want to apply an eclipse theme and you end up with this lovely error.
Opening the xsp-config file is just as fun. First if you double click you get notepad (on windows)
So you might instead try to Open With -> Xml Editor
but then you get this:
and end up with the normal text editor (with no pretty colours!)
So how do we fix this? We have to add these as content types in the preferences section as below.
Find the ‘XML’ Content Type and select it, click ‘Add..’ in the File associations section, type in the new extension to associate and click ok
In the picture below I am doing it for *.theme files and you can also see I have already done it for *.xsp-config
Now let’s see what happens when we double click our theme file:
We have our pretty colours and XML editor!
And if you are crazy like me and are playing around with loading xpages from within a plugin using the XPages Bazaar then maybe you will do it for .xsp too 🙂
