Hola buenas,Estoy realizando un programa que me permita subir y descargar un fichero con web services. El caso es que me lo sube correctamente, pero no me deja descargarlo. En cambio, si en vez de subirlo a través de mi aplicación, lo hago desde el propio Alfresco, sí puedo descargarlo a través de mi aplicación.Por ello supongo que el problema está en la subida, que me faltará algo que sea necesario detectar en la descarga.Adjunto el código de la subida:public class UploadAction extends Action {
String loginName = StandardSQLUserProfileDAO.loginName;
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
if (!(form instanceof UploadForm)) {
return mapping.findForward(mapping.getInput());
}
System.out.println("Executing AddContentAction…");
// Recogemos los parametros del fichero
UploadForm theForm = (UploadForm) form;
FormFile theFile = theForm.getTheFile();
String contentType = theFile.getContentType();
String fileName = theFile.getFileName();
int fileSize = theFile.getFileSize();
byte[] fileData = theFile.getFileData();
String description = theForm.getDescription();
String id = UploadContentAction.id;
String destinatario = UploadContentAction.destinatario;
System.out.println(" > Nombre: " + fileName);
System.out.println(" > Tipo: " + contentType);
System.out.println(" > Tamaño: " + fileSize);
System.out.println(" > Descripcion: " + description);
System.out.println(" > Id procedimiento: " + id);
System.out.println(" > Destinatario: " + destinatario);
try
{
AuthenticationUtils.startSession("admin", "admin");
Store storeRef = new Store(Constants.WORKSPACE_STORE, "SpacesStore");
Reference reference = new Reference(storeRef, null, "/app:company_home/*[@cm:name=\"" + "User Homes" + "\"]/*[@cm:name=\"" + destinatario + "\"]");
ParentReference parentRef = new ParentReference();
parentRef.setStore(storeRef);
parentRef.setUuid(reference.getUuid());
parentRef.setPath(reference.getPath());
parentRef.setAssociationType(Constants.ASSOC_CONTAINS);
parentRef.setChildName(Constants.ASSOC_CONTAINS);
// Comienza la construcción de nodo
NamedValue[] contentProps = new NamedValue[5];
contentProps[0] = Utils.createNamedValue(Constants.PROP_NAME, fileName);
contentProps[1] = Utils.createNamedValue(Constants.PROP_TITLE, "1");
contentProps[2] = Utils.createNamedValue("{http://www.alfresco.org/model/content/1.0}email-id", id);
contentProps[3] = Utils.createNamedValue(Constants.PROP_DESCRIPTION, description);
contentProps[4] = Utils.createNamedValue("{http://www.alfresco.org/model/content/1.0}author", loginName);
CMLCreate create = new CMLCreate();
create.setParent(parentRef);
create.setProperty(contentProps);
create.setType(Constants.TYPE_CONTENT);
CML cml = new CML();
cml.setCreate(new CMLCreate[] {create});
UpdateResult[] result = WebServiceFactory.getRepositoryService().update(cml);
Reference content = result[0].getDestination();
ContentServiceSoapBindingStub contentService = WebServiceFactory.getContentService();
ContentFormat contentFormat = new ContentFormat(contentType, "UTF-8");
contentService.write(content, Constants.PROP_CONTENT, bytes, contentFormat);
}
catch (Exception e) {
throw new InternalErrorException(e);
}
finally
{
AuthenticationUtils.endSession();
}
return mapping.findForward("HomePage");
}
}
Y el código de descarga:public class DescargarAction extends DefaultAction {
public ActionForward doExecute(ActionMapping mapping,
ActionForm form, HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException, InternalErrorException {
String loginName = StandardSQLUserProfileDAO.loginName;
String fileName = request.getParameter("name");
/**Start the session*/
AuthenticationUtils.startSession("admin", "admin");
/** Make sure Service Folder has been created,or download files will be failure */
boolean Success = true;
Store storeRef = new Store(Constants.WORKSPACE_STORE, "SpacesStore");
String parentSpace = "/app:company_home/*[@cm:name=\"" + "User Homes" + "\"]/*[@cm:name=\"" + loginName + "\"]";
Reference SAMPLE_FOLDER = new Reference(storeRef, null, parentSpace);
try
{
WebServiceFactory.getRepositoryService().get(new Predicate(new Reference[]{SAMPLE_FOLDER}, storeRef, null));
}
catch (Exception exception)
{
System.out.println("Error while getting repository service");
Success=false;
}
/**Download files,if exception then "Success = False" */
try
{
if(Success)
{
ContentServiceSoapBindingStub contentService = WebServiceFactory.getContentService();
Reference contentReference = new Reference(storeRef,null,parentSpace+"/cm:"+fileName);
Predicate pred = new Predicate(new Reference[]{contentReference}, storeRef, null);
Content[] readResult = contentService.read(pred, Constants.PROP_CONTENT);
for(Content content: readResult)
{
String[] splitedUrl = content.getUrl().split("/");
if(splitedUrl[splitedUrl.length-1].equals(fileName))
{
InputStream in=ContentUtils.getContentAsInputStream(content);
response.reset();
response.setHeader ("Content-Disposition", "attachment;filename=\""+fileName+"\"");
ServletOutputStream sosStream = response.getOutputStream();
int ibit = 256;
while ((ibit) >= 0)
{
ibit = in.read();
sosStream.write(ibit);
}
sosStream.flush();
sosStream.close();
in.close();
}
}
}
}
catch(ClientAbortException e)
{
System.out.println("File download cancelled by the user");
}
catch(Exception e)
{
System.out.println("Error downloading file : "+e.getMessage());
}
AuthenticationUtils.endSession();
return mapping.findForward(mapping.getInput());
}
}
Si alguien me pudiera ayudar lo agradecería. Muchas gracias.
