Spring integration for Axis2

[Gihan Madushanka]

Hi All,


I'm Gihan Madushanka  an undergraduate and planning to participate GSoC
2013 program. I'm planning to develop a new Spring integration project for
Axis2 based on two 3rd party projects called  WSO2 WSF-Spring and Axis2M.
In present both the above projects seem not active also I noticed that
there were few discussions happened on Axis2 developer mailing list time to
time but didn't make continuous progress.  I have studied  Axis2M code base
up to some extend and managed to run samples mentioned here
http://axis2m.sourceforge.net/spring.html further I'm planning to start my
initial tasks around this code base. I found following
http://wso2.org/projects/wsf/spring page and
http://wso2.org/library/3208tutorial  about WSO2 WSF-Spring but
couldn't find neither code base or
downloads.


For the moment I found following points as objectives of this projects.


1.) Use Spring application context file to configure Axis2 framework
without using axis2.xml file.

2.) Use Spring application context file to add Axis2 web services and Axis2
modules.

3.) Use Spring application context file to access Axis2 web service from
client side.


I  appreciate if you can help me to find more objectives and to identify
scope and priority of  above objectives. Further please let me know the
procedure which  I should follow before  submitting my proposal to GSoC
program.



Regards,


Gihan

This can be a good addition to Axis2 transport module. I'm not quite sure
about EPL ( which used by the Eclipse Paho) is compatible with Apache if
there is no issue then you can contribute your codes to Axis2 project.
Please create a JIRA and attach your SVN patch against current trunk. One
thing I noticed is you have to provide more test cases for this transport
implementation.

Thanks !

  This idea still on my TO-Do list for a long time. I'm definitely happy to
see this project as a Axis2 module and probably I can be a mentor too.

 WSF Spring code base moved to  Github, you can find link for new code base
from here[1].

It's completely Ok to study both Axis2M, WSF Spring projects and get start
your effort around those code bases but I would encourage you to take a
look on this code base on Axis2 scratch area. This new code base was
developed by merging best ideas of both of above projects plus some new
ideas such as component scanning for JSR 181 beans, personally I believe
scratch project is much cleaner and more close to Spring practices so
better to use this code as you initial code base.

Please refer following thread[3] if you haven't find it yet, also following
wiki  page [4] may helpful. BTW can you create a JIRA issue here[5]  so
that I can add more content there ?

HI Sagara,

First of all thanks a lot for your quick response, details you provided are
really valuable to me. I will study and try to test the new code base you
provided in your mail.  As you informed I have created a jira here
https://issues.apache.org/jira/browse/AXIS2-5510 please kind enough to
check it and correct any mistake. *

Re: MQTT transport for Axis2

[Pradeep Fernando]

Hi Sagara,

Thanks for the feedback.
Will create a proper patch against the axis2 trunk and attach. Yes I have
to work on test cases. Will start working on that aspect as well.

thanks,

@Kishanthan: Miguel is right. If you observation of what the code does is 
correct, then the problem is not on the server side, but the client side.

Re: Jenkins build is unstable: Rampart #1446

[Andreas Veithen]

I remember that at some point the test suite required unlimited
strength encryption and that somebody went over all the test cases to
change that. Maybe you could search in the archives to check what were
the reasons for that and if they are still applicable today. If they
still are, then you need to change the test cases.

Re: org.apache.axis2.AxisFault: com.ctc.wstx.exc.WstxUnexpectedCharException

[Raghu Veer]

Hello,



I get the below exception when I try to process the response received from an 
axis2 web service. Web service client and server stubs were generated using 
Axis 2 version 1.6.2 wsdl2java. The server side code works fine if run on 
Tomcat 6 but has this issue on WebLogic 11.

Unexpected character ':' (code 58) excepted space, or '>' or "/>"

Please advice.
