      Description

      I am trying to upload and download large binary files with axis2 using MTOM. I am able to upload upto 2GB file without any memory issue either at server side or client side. But when downloading file from server to client, client is getting out of memory, though the server is sending a stream.

      When the response received at client side, javax.activation.Datahandler is embedded in the response which is a pointer to InputStream. Ideallly it should not give out of memory. And this is the same mechanism while uploading, and there is no problem at that end.

      Seems to be a bug at client side handling of large documents in response stream.

      catch (FileNotFoundException e)

      { e.printStackTrace(); }

      return null;
      }
      }

      And the client code

      public static void main(String[] args) throws Exception

      { SampleServiceStub stub = new SampleServiceStub(); stub._getServiceClient().getOptions().setProperty(Constants.Configuration.ENABLE_MTOM, Constants.VALUE_TRUE); //stub._getServiceClient().getOptions().setProperty(Constants.Configuration.ENABLE_SWA, Constants.VALUE_TRUE); stub._getServiceClient().getOptions().setTimeOutInMilliSeconds(1000*60*10 ); //stub._getServiceClient().getOptions().setProperty(Constants.Configuration.CACHE_ATTACHMENTS, Constants.VALUE_TRUE); //stub._getServiceClient().getOptions().setProperty(Constants.Configuration.ATTACHMENT_TEMP_DIR, "c:/tmp"); //stub._getServiceClient().getOptions().setProperty(Constants.Configuration.FILE_SIZE_THRESHOLD, "4000"); SampleRequestType type = new SampleRequestType(); type.setFileName("server.log"); type.setContentType("text/plain"); SampleRequest request = new SampleRequest(); request.setSampleRequest(type); SampleResponse response = stub.sampleRequest(request); }
