Hi Martin and Andreas, I am little bit confused with your responses. Not able to identify whether it is issue of spring,xalan or axiom. I am also hitting my head in various disscussion threads but not getting any satisfactory response.
Rgrds,Rohit -----Original Message----- From: Andreas Veithen [mailto:[email protected]] Sent: Wednesday, December 09, 2015 2:39 AM To: dev Cc: Rohit Singh Subject: Re: OutOfMemory issue with Axiom The VisualVM screenshot also shows a large amount of memory consumed by byte[]. This suggest that the application uses Spring-WS's PayloadTransformingInterceptor on the message. You shouldn't do that for large messages, because the code in PayloadTransformingInterceptor introduces a large overhead: ByteArrayOutputStream os = new ByteArrayOutputStream(); transformer.transform(message.getPayloadSource(), new StreamResult(os)); ByteArrayInputStream is = new ByteArrayInputStream(os.toByteArray()); transform(new StreamSource(is), message.getPayloadResult()); It will transform the original payload and serialize the result into a byte array. It will then deserialize that intermediate result to build an Axiom tree (This is where the leak in Xalan occurs). Unfortunately it's necessary to use an intermediate byte array because of the way Spring-WS is architected. If possible, you should get rid of PayloadTransformingInterceptor.
