OOM Exception with MTOM client

Question

I am working on transfer large size file, and finally ended with MTOM implementation. we created MTOM enabled web service and client, and tested the client as a plain Java program. and we were able to send 1 GB file successfully. the main point here the heap at client place were not even increasing more than 70 MB.

But when I tried to initiate the same call from web-logic container (means created web client), we end up with below OOM Exception.

anyu one have any idea

UPDATE: it seems the MTOM settings are not effective when we run the program in web-logic container ! but still I am not able to find the solution

UPDATE 2: it seems weblogic is not supporting streaming ! I will update the weblogic version and update the ticket, till them wish me luck..

could you please share the example code? I am trying to write the same but for unknown reason the client buffers the entire data in memory — yolob 21, Apr 28 '20 at 14:55

Add this additional Java/JVM Option in setDomainEnv.sh

EXTRA_JAVA_PROPERTIES="-DUseSunHttpHandler=true ${EXTRA_JAVA_PROPERTIES}"
export EXTRA_JAVA_PROPERTIES

switches from weblogic specific (weblogic.net.http.HttpURLConnection) to sun's HTTP handler.

This solved my issue.

Refer:
