Improve Axis2 JAX-WS performance
Dear Sir/Madam,
While searching a GSoC project idea, I got to know about Axis2 project
having potential opportunity to work on its JAX-WS implementation.
According to the facts I gathered, I have created a JIRA issue here
https://issues.apache.org/jira/browse/AXIS2-5509. As foremost objective I'm
planning to find bottlenecks of Axis2 JAX-WS framework and suggest possible
solutions during the project period. I have some experience about JAX-WS
programming model but it is based on Metro framework on JBoss server.
During recent past I tried to develop few Axis2 based JAX-WS services and
managed to run set of basic samples. I'm much obliged if someone can guide
me to find out a direction.
Thanks in advance
Danushka Seneviratne

Dear Sagara,
Thanks a lot for your mail and provided details. I will study them and will
try to follow the same path. I will send an another mail once I make
progress on initial steps.
Thanks in advance

RE: Improve Axis2 JAX-WS performance
Posted by Martin Gainty <mg...@hotmail.com>.
google-code implements guice as the main Injector but previously I've used
Plexus Injector specifically for injecting annotated artifacts via Plexus Framework in Maven
Spring Injector specifically for injecting annotated artifacts via Spring Framework
If you are working in 'Google Summer Of Code' there is an *assumption* that you will use guice for your injector
SAX is an event driven way of constructing DOM Objects 'on the fly' vs DOM where you the whole Document prior to usage..
SAX was created for situations where on the fly construction of your DOM can be achieved based on known 'events'
DOM always works..but you are beholden to construct the entire DOM Document prior to usage
http://en.wikipedia.org/wiki/Simple_API_for_XML
Statics are artifacts of what used to be called global variables..They are not ThreadLocal statics are generally considered by the Heap Manager as the last objects to be collected
Concerning JAX-WS not alot you can do take a look at
http://www.mkyong.com/webservices/jax-ws/jax-ws-hello-world-example-document-style/
Refactoring statics in main is not available
the only path I can suggest is to implement JavaProfiler and HTTP Profiler and determine
1)who or what is consuming the most amount of memory
2)can the transmitted information be
2a)compressed OR
2b)reduced in some matter
Run the code thru a Profiler to determine who is consuming the most memory
http://www.ej-technologies.com/products/jprofiler/overview.html
http://www.quest.com/jprobe/
http://www.purescm.com/services-solutionmenu-49/enterprise-a-infrastructure-solutionmenu-114/ca-wily-introscope-solutionmenu-171
Wily has rules for thresholds for timeout which is a good tool for determining which service is
taking excessive time
Keep us apprised,
Martin Gainty

Dear Martin,
Thanks a lot for your mail, is it possible you to provide some references about your project ideas ? I'm still new to this area and still couldn't understand your suggestions.
Thanks in advance

refactor n{repeated set of statements} into common functions
are there any caveats to using GSoC ?

Sometimes back I did a profiling to identify performance issues of JAX-WS
implementation you can read what I found from here [1]. Based on my
findings I started to write improved version of JAX-WS but couldn't manage
to make much progress with my time restrictions, basically I wrote a custom
MethodMarshaller[2] and plugged into the existing architecture. I'm not

If you really want to make this idea into GSoC project then it's required
to understand issues on current architecture first but this depends on of
how well you understand the architecture of existing implementation. My
recommendation is spend some time initially and come up with detail

these are the possible ways of solution etc. Any way you have to be quick
