Custom action: ClassNotFound ActionExecuterAbstractBase

I'm trying to deploy a custom action. I've developed the custom action as explained in the Wiki, extending ActionExecuterAbstractBase.

But when I restart tomcat to load the new action I get this error:

16:46:40,723 ERROR [org.springframework.web.context.ContextLoader] Context initialization failed
org.springframework.beans.factory.CannotLoadBeanClassException: Error loading class [es.binovo.alfresco.action.LegalXMLParser] for bean with name 
'legal-xml-parser' defined in file [/var/lib/tomcat5.5/shared/classes/alfresco/extension/legal-xml-parser-context.xml]: problem  with class file or dependent class; nested exception is java.lang.NoClassDefFoundError: org/alfresco/repo/action/executer/ActionExecuterAbstractBase
Caused by: java.lang.NoClassDefFoundError: org/alfresco/repo/action/executer/ActionExecuterAbstractBase

ActionExecuterAbstractBase does exist, in fact all the preconfigured actions reference this bean in the same way I'm doing, using the action-executer name. This bean seems already configured as the code "knows" that is needs the ActionExecuterAbstractBase so … Why isn't this working ?

The class looks like this:

package es.binovo.alfresco.action;

import java.util.List;

import org.alfresco.repo.action.ParameterDefinitionImpl;
import org.alfresco.repo.action.executer.ActionExecuterAbstractBase;
import org.alfresco.service.cmr.action.Action;
import org.alfresco.service.cmr.action.ParameterDefinition;
import org.alfresco.service.cmr.model.FileFolderService;
import org.alfresco.service.cmr.repository.ContentReader;
import org.alfresco.service.cmr.repository.NodeRef;
import org.alfresco.service.cmr.repository.NodeService;

import org.apache.log4j.Logger;

   /** The FileFolderService to be used by teh bean */

      ContentReader rawXML = fileFolderService.getReader(actionedUponNodeRef);
      rawXML.setMimetype("text/xml");
      String message = rawXML.getContentString();
      logger.debug(message);

   public void setNodeService(NodeService nodeService) {

I've compiled it and placed the class in a {tomcat_directory}/shared/classes/es/binovo/alfresco/action/LegalXMLParser.class.

I also created legal-xml-parser-context.xml and placed it in {tomcat_directory}/shared/classes/alfresco/extension/, with content:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN' 'http://www.springframework.org/dtd/spring-beans.dtd'>

Well, I was just copying my classes to alfresco extension's class directory, I have packed them in a JAR file and placed it in Alfresco's webapp's lib path and it works.

It seems that the classpath is not the same when the classes are loaded from the extension's path and the webapp's lib path. Maybe it is obvious for all live long Java guy, but I was formerly a PHP guy.
