Buenos días ciberbec,

Te recomiendo que bajes el Alfresco SDK, que incluye ejemplos muy ilustrativos del uso y manejo de los web services de alfresco.
En la siguiente URL encontrarás las instrucciones de instalación y demás: http://wiki.alfresco.com/wiki/Alfresco_SDK
No obstante, como te urge, he hecho un poco los deberes por ti y te paso un ejemplo de creación y actualización de contenido :wink:
package org.alfresco.sample.webservice;

import java.io.InputStream;

import org.alfresco.webservice.content.Content;
import org.alfresco.webservice.content.ContentServiceSoapBindingStub;
import org.alfresco.webservice.repository.UpdateResult;
import org.alfresco.webservice.types.CML;
import org.alfresco.webservice.types.CMLCreate;
import org.alfresco.webservice.types.ContentFormat;
import org.alfresco.webservice.types.NamedValue;
import org.alfresco.webservice.types.ParentReference;
import org.alfresco.webservice.types.Predicate;
import org.alfresco.webservice.types.Reference;
import org.alfresco.webservice.util.AuthenticationUtils;
import org.alfresco.webservice.util.Constants;
import org.alfresco.webservice.util.ContentUtils;
import org.alfresco.webservice.util.Utils;
import org.alfresco.webservice.util.WebServiceFactory;
