LocalizationBundle for title not working in portlet (wlp 10.3)

Question

Hi!
I'm trying to use the localizationBundle, in order to get different titles for my portlets (and further books, pages, etc) depending on the user locale.
I've followed these instructions:
http://download-llnw.oracle.com/docs/cd/E13155_01/wlp/docs103/portals/develop_portals.html#wp1062140
So I created a portlet as indicated above.
This is my portlet xml:
<?xml version="1.0" encoding="UTF-8"?>
<portal:root xmlns:netuix="http://www.bea.com/servers/netuix/xsd/controls/netuix/1.0.0"
xmlns:portal="http://www.bea.com/servers/netuix/xsd/portal/support/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.bea.com/servers/netuix/xsd/portal/support/1.0.0 portal-support-1_0_0.xsd">
<netuix:portlet definitionLabel="pruebasIntenacional2"
title="Titulo por defecto"
titleKey="pruebasIntenacional2.title.key"
localizationBundle="resources.titulosPortlets">
<netuix:titlebar/>
<netuix:content>
<netuix:jspContent contentUri="/portlets/pruebasintenacional2/pruebasIntenacional2.jsp"/>
</netuix:content>
</netuix:portlet>
</portal:root>
And I created the folder
/resources
under WEB-INF/src
The folder "resources" contains the following bundles:
titulosPortlets.properties
titulosPortlets_en.properties
titulosPortlets_es.properties
And all of the bundles have their "pruebasIntenacional2.title.key" key and value. Example:
pruebasIntenacional2.title.key = Título en castellano
but all the time the title displayed is "Titulo por defecto", the property "title" of the portlet.
Is there anything else I need to do?
Thanks in advance.

Thank you Brad, but I have no luck.
I've copied the properties files into 'classes' folder but it doens't work either. I think bundles are in the classpath because in a java class (PageFlowController) I can get them without problem, but in the portlet the title is never resolved from the localizedBundle.
Do you have any clue about what is happening? Is it possible to see something in a log file or using debug.properties?
I don't know what else to do to make it works...
