Memory foot print on server is very high while streaming XML in Axis2
---------------------------------------------------------------------
Key: AXIS2-483
URL: http://issues.apache.org/jira/browse/AXIS2-483
Project: Apache Axis 2.0 (Axis2)
Type: Bug
Components: om
Versions: 0.94
Environment: Windows XP, JDK 1.5.05
Reporter: Lakshmi Chaparala
Our Axis2 service is currently implemented as suggested and the xml is
streaming back to the client ok. The problem we're having is that the memory
footprint on the server is larger than we'd like.
We are creating a large xml result for a query in our Axis2 service
implementation. So we end up with a large xml result in a
ByteArrayOutputStream that we need to send back to the client. Using the
standard implementation suggested below doubles the memory footprint on the
server to create the OMElement that is returned by the service implementation
method. We'd like to be able to send the xml we have in memory over the wire
without creating the OMElment objects. Even better, we'd like to start
streaming back the xml result as it is being created. Is there any way to
implement an Axis2 service that either has OMElement caching off when it
streams back to the client or streams a result back to the client as it is
being created?
