Cool. Who is the mentor?

architecture of Apache WSDL2Java Code generator. The idea is to generate both service deployment
and client side code for a particular web service from its WSDL(Web Service Description Language),
making the task of web service programmers quick and effortless.

API which make it possible to plug the code generator into famous IDEs like Eclipse/ Microsoft
Visual Studio. The most challenging part of the project is to keep high performance and modularity
provided by the Axis2C Web services engine and generate the most optimized code from any complex
Web service Description.

>I am a third year student specializing Computer science and Engineering for my B Sc Engineering
degree in University of Moratuwa in Sri Lanka. I am very new to Open source software development
but I have contributed to some non-open source projects previously including a local competition
held by National Institute of Education in last year (2005) for best educational software
and was placed the runner-up. My project was to make a simulator for chemical organic reactions
targeting the syllabus of local Advanced level examination. Some of my projects are listed
>Recently web services become my first interest as I have good guidance from web service
implementors who works on Apache Axis2 Project. I have written client programs using Apache
Axis2/C web service engine to invoke simple web services like Google spell check. And requirement
of a code generation tool arouse when trying to handle complex web services. These days I
am working on developing a Mozilla extension for consuming Web services using Axis2/C engine
and I was  successful in implementing XML in/out model and asynchronous invocations with a
very similar API as AJAX.
>Although I have not directly contributed  to Axis2/C project yet, I've been very much
aware of the project for the last few months by lurking in the mailing lists. I often download
the latest source from SVN and refactor my web service clients accordingly. I have come across
several bugs in the engine when I run clients and fixing these bugs have made the code more
>I feel Google summer of code would provide me a good opportunity to get involved in the
Apache Web Service Projects as a university student. WSDL2C code generator would be a key

I hope I can accomplish this in time with the guidance of people who implement the WSDL2Java
tool and who are working on Axis2 projects.
