Error al subir archivo mediante Webservice

kunkunkunkun · ‎21 Feb 2011

Hola, llevo un par de días con el asunto, y no logro sacarlo adelante, la cosa es que tengo hecho un dialog, similar al "add content" , la única diferencia, es que en vez de subir un archivo que tienes almacenado en tu PC, cuando pulsas el botón, éste maneja una clase java que llama al escáner y obtiene la imagen. (hasta ahí bien, y sencillito).
Una vez que tengo la imagen, en un bufferedimage, mi intención es que automáticamente sea subida mediante webservices. Pero pega un error que no consigo acatar

Este es el log del error:


javax.faces.FacesException: Error calling action method of component with id dialog:dialog-body:_idJsp19

Jobar me estoy volviendo loco,
Nadie tiene alguna idea?

elessar_7190 · ‎24 Feb 2011

Pues por la pinta (y disparando un poco a ciegas) te diría que es alguna librería, algún jar que te falte, porque te pega el casque aquí:

NoClassDefFoundError: org/alfresco/webservice/types/Store

Es decir, que no ecuentra la clase org.alfresco.webservice.types.Store

Intuyo que te la da, por esta línea de código
Store store = new Store(Constants.WORKSPACE_STORE, "SpacesStore");

Una rápida búsqueda en google me lleva aquí: http://forums.alfresco.com/en/viewtopic.php?f=27&t=27994 A ver si esto te ayuda un poco.

Qué va, he montado de nuevo todo el alfresco y empezao de cero con eclipse, y están todas las librerías.
Es raro, porque ese mismo código lo monté hace tiempo en un applet que interactuaba con alfresco y funcionaba bien.

kunkunkunkun · ‎7 Mar 2011

A ver, expongo alguna novedad:
Primero, desde mi página JSP a través de un botón llamo a la clase Java.
Esta clase, llama a tu dispositivo (escaner, camara o lo que sea), recoge la imagen, y la sube al servidor Alfresco mediante webservices.

Ahora bien, si lo convierto en Applet funciona, si lo ejecuto desde eclipse, a la perfección.
Pero cuando compilo con Ant desde eclipse, arranco tomcat y alfresco, cuando pincho en el botón, nanai.

Mi pregunta, porqué desde eclipse lo ejecuto como una clase Java, se conecta al servidor alfresco y funciona perfectamente, mientras que si lo llamo desde jsp no funciona???

Llamo mal desde Jsp a la clase y su método java??

He aquí el error:

Luego tengo otra clase que hereda de esta, que es la que recoge la imagen y la sube… pero bueno el error lo pega aquí, a la hora de conectarse mediante WebServices.

La clase la llamo desde Jsp de la siguiente forma,

añado los imports,
<%@ page import="org.alfresco.webservice.ejustice.Cliente"%>
<%@ page import="org.alfresco.webservice.ejustice.ContentReadAndWrite"%>

y tengo un botón que me llama al método correspondiente de la clase:
<h:commandButton value="#{sms.scan}" actionListener="#{scan.prin}"/>

Me desespero
