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;

/**

public class LegalXMLParser extends ActionExecuterAbstractBase {
   
   public final static String NAME = "legal-xml-parse";
   
   /** The NodeService to be used by the bean */
   protected NodeService nodeService;

   /** The FileFolderService to be used by teh bean */
   protected FileFolderService fileFolderService;

   private static Logger logger = Logger.getLogger(LegalXMLParser.class);
   
   @Override
   protected void executeImpl(Action action, NodeRef actionedUponNodeRef) {
      // TODO Auto-generated method stub
      if (logger.isDebugEnabled()) logger.debug("Inside executeImpl");
      
      //Map<QName, Serializable> properties = nodeService.getProperties(actionedUponNodeRef);
      
      ContentReader rawXML = fileFolderService.getReader(actionedUponNodeRef);
      rawXML.setMimetype("text/xml");
      String message = rawXML.getContentString();
      logger.debug(message);
      
   }

   /* (non-Javadoc)
    * @see org.alfresco.repo.action.ParameterizedItemAbstractBase#addParameterDefinitions(java.util.List)
    */
   @Override
   protected void addParameterDefinitions(List<ParameterDefinition> paramList) {
      // TODO Auto-generated method stub
      logger.debug("Inside addParameterDefinitions");
   }
   
   /**
   * @param nodeService The NodeService to set.
   *
   * Este método es el que proporciona un enganche para que con la configuración
   * Spring que hagamos de esta acción de podamos pasar el servicio de nodos
   * de Alfresco.
   * 
   */
   public void setNodeService(NodeService nodeService) {
      this.nodeService = nodeService;
   }

   public void setFileFolderService(FileFolderService fileFolderService){
      this.fileFolderService = fileFolderService;
   }
}

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'>

<beans>
   <!– Parse generated XML –>
   <bean id="legal-xml-parser" class="es.binovo.alfresco.action.LegalXMLParser" parent="action-executer">
      <property name="nodeService">
         <ref bean="NodeService" />
      </property>
      <property name="fileFolderService">
         <ref bean="FileFolderService" />
      </property>
      <property name="publicAction">
         <value>true</value>
      </property>
   </bean>   
</beans>
