Hi all,

I want to integrate an applet into Alfresco. This applet scan a file from device, save it in the local machine and then upload it into Alfresco. To upload the file the applet use Alfresco webservices. This is the code:

public void saveAlfresco(File file){
     
     String userName = "admin";
     String password = "admin";
     
      try
      {     
         String serverhost = "http://localhost:8080/alfresco/api";
       // Start the session
         System.out.println("Start the session");
         AuthenticationUtils.startSession(userName, password);
                   
          // Get the content service
          System.out.println("Get the content service");
          ContentServiceSoapBindingStub contentService = WebServiceFactory.getContentService(serverhost);        
          
          Store store = new Store(Constants.WORKSPACE_STORE, "SpacesStore");
         String ASSOC_CONTAINS = "{http://www.alfresco.org/model/content/1.0}contains";
         String uuid = properties.getProperty("container").toString();
         String filename = properties.getProperty("scanFile").toString();
         
         System.out.println("Create a parent reference");
         // Create a parent reference, this contains information about the association we are createing to the new content and the
         // parent of the new content (the space retrived from the search)
         ParentReference parentReference = new ParentReference(store, uuid, null, ASSOC_CONTAINS, 
                 "{" + Constants.NAMESPACE_CONTENT_MODEL + "}" + filename);
         
         System.out.println("Define the content format new ContentFormat('image/tiff', 'UTF-8')");
         // Define the content format for the content we are adding
         ContentFormat contentFormat = new ContentFormat("image/tiff", "UTF-8");
         
         NamedValue[] properties = new NamedValue[]{Utils.createNamedValue(Constants.PROP_NAME, filename)};
         CMLCreate create = new CMLCreate("1", parentReference, null, null, null, Constants.TYPE_CONTENT, properties);
         CML cml = new CML();
         cml.setCreate(new CMLCreate[]{create});
         UpdateResult[] result = WebServiceFactory.getRepositoryService().update(cml);
         Reference newContentNode = result[0].getDestination();
         
         FileInputStream fileInputStream = new FileInputStream(file);
         byte[] bytes = ContentUtils.convertToByteArray(fileInputStream);
       
         System.out.println("Add content");
         Content content = contentService.write(newContentNode, Constants.PROP_CONTENT, bytes, contentFormat);
      
         System.out.println("Saved!!!! " + content.getUrl());

      }catch (RemoteException e) {
      e.printStackTrace();
   } catch (FileNotFoundException e) {
      e.printStackTrace();
   } catch (Exception e) {
      e.printStackTrace();
   }
      finally
      {
          // End the session
          AuthenticationUtils.endSession();
      }
  }

This code return an error when execute this line:

AuthenticationUtils.startSession(userName, password);
‍‍‍

and then when it run this line:

AuthenticationUtils.endSession();
‍‍‍

the following error appears in Java console:

The userName and password are correct. What´s the problem? Does It need more configuration? I never use web services before.

Thanks a lot in advance,

Before starting the session you have to set the endpoint address in this way:

WebServiceFactory.setEndpointAddress(serverhost);
AuthenticationUtils.startSession(userName, password);
…

Hope this helps.
