Send Attachment

[fedemori]

Hi,
I'm creating a client to connect to Activiti with REST.
I logged in correctly and start the process with variables but I can't send an attachment.
Can you help me? This is my code.

HttpResponse response = null;
      String processInstanceId = null;      
      String taskDefinitionKey = null;
      String taskId = null;
      
      CryptUtil crypt = CryptUtil.getInstance();
      String pwdCrypt = crypt.encrypt(password);
      DefaultHttpClient client = new DefaultHttpClient();
      client.getCredentialsProvider().setCredentials(new AuthScope("localhost", 8080),
          new UsernamePasswordCredentials(user, pwdCrypt));
 
      // Create AuthCache instance
      AuthCache authCache = new BasicAuthCache();
      // Generate BASIC scheme object and add it to the local auth cache
      BasicScheme basicAuth = new BasicScheme();
      authCache.put(new HttpHost("localhost", 8080, "http"), basicAuth);
 
      // Add AuthCache to the execution context
      BasicHttpContext localcontext = new BasicHttpContext();
      localcontext.setAttribute(ClientContext.AUTH_CACHE, authCache);
         
      try {
         HttpPost postMethod = new HttpPost("http://localhost:8080/activiti-rest/service/process-instance");
         LoadProp lprop = new LoadProp();
         String procUOIA = lprop.getProcKeyUOIA();
         String groupUOIA = lprop.getGroupUOIA();
         taskDefinitionKey = lprop.getTaskDefinitionKey();
                  
         Format formatter = new SimpleDateFormat("dd/MM/yyyy HH:mm");
         String sData = formatter.format(data);
         
         JSONObject jsonObj = new JSONObject();
         jsonObj.put("processDefinitionId", procUOIA);
         jsonObj.put("mittente", mittente);   
         jsonObj.put("oggetto", oggetto);   
         jsonObj.put("data", sData);   
         jsonObj.put("note", note);
         jsonObj.put("group", groupUOIA);
         //postMethod.setEntity(new StringEntity("{\"processDefinitionId\":\"" + procUOIA + "\"}", "UTF-8"));
                     
         StringEntity se = new StringEntity(jsonObj.toString(),"UTF-8");  
         se.setContentType(new BasicHeader(HTTP.CONTENT_TYPE, "application/json"));
         postMethod.setEntity(se);

           }

Please add the exception that you're experiencing…

<java>
File test = new File("E:/lecce.doc");
  
   HttpPost postMethod =
     new HttpPost("http://localhost:8080/activiti-rest/service/task/" + taskId + "/attachment" );
  
   //FileEntity fileEntity = new FileEntity(test);
   //fileEntity.setContentType(FileUtil.getMimeType(test));
   InputStreamEntity reqEntity = new InputStreamEntity(
           new FileInputStream(test), test.length());
  
  
   //reqEntity.setContentEncoding(FileUtil.getMimeType(test));
   reqEntity.setContentType(FileUtil.getMimeType(test));
   reqEntity.setChunked(true);
   postMethod.setEntity(reqEntity); 
   response = client.execute(postMethod, localcontext);
</java>
the response send code 405 Method not Allowed

[fedemori]

I use Activiti 5.11

<code>
Add attachment to a task
Add an attachment to a task instance

Request: PUT /task/{taskId}/attachment

{}

</code>

You have posted the answer yourself, use PUT instead of POST (hence the 405, method not allowed):
HttpPost postMethod = and
Request: PUT /task/{taskId}/attachment
