------------------------------------
Summary: Axis2 MTOM client outof memory error when downloading
file from service
Key: AXIS2-5301
URL: https://issues.apache.org/jira/browse/AXIS2-5301
Project: Axis2
Issue Type: Bug
Components: adb, databinding
Affects Versions: 1.6.1
Environment: Windows XP , Axis2 1.6.1, JDK 1.5
Reporter: Sridhar Ratna
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.
