Prettyfaces, it's not been resolved?

I'm trying to build custom URL as prettyfaces tells that it do, but after setup it, it gives me this error:

Referenced file contains errors (http://ocpsoft.org/xml/ns/prettyfaces/ocpsoft-pretty-faces-3.3.3.xsd). For more information, right click on the message in the Problems View and select "Show Details..."

This is how my web.xml setup:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

   </filter>

   <filter-mapping>

      <dispatcher>REQUEST</dispatcher> 
      <dispatcher>ERROR</dispatcher>
      <dispatcher>ASYNC</dispatcher>
   </filter-mapping>
</web-app>

And my pretty-config.xml :

<pretty-config xmlns="http://ocpsoft.org/prettyfaces/3.3.3" 
               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
               xsi:schemaLocation="http://ocpsoft.org/prettyfaces/3.3.3
               http://ocpsoft.org/xml/ns/prettyfaces/ocpsoft-pretty-faces-3.3.3.xsd">

    <url-mapping id="home">
        <pattern value="/home" />
        <view-id value="/index.xhtml" />
    </url-mapping>

With this error I can't even deploy my app in Glassfish:

Could not publish to the server.
java.lang.NullPointerException

Any idea how to fix this ? Or should I look for another tool similar to prettyfaces ?

update

I don't think that this error is caused by PrettyFaces. The XML schema works fine in my Eclipse setup and I don't get any of these errors. And I'm pretty sure that the XSD file is valid.

You should have a look at the Eclipse log file (WORKSPACE/.metadata/.log) to have a look if there is any exception thrown.

BTW: You could also try to remove the schemaLocation element from your pretty-config.xml and check if this helps. PrettyFaces doesn't use the XSD schema when parsing the file. Something like this:

<pretty-config xmlns="http://ocpsoft.org/prettyfaces/3.3.3">
  ...
</pretty-config>
