Developer Guide needed about Axis2/C internals

2008-03-03T09:35:00.000-08:00

I think it is time to have a sound developer guide for Axis2/C web services stack as there are increasing number of developers all over the world contributing to the project. While I was writing Sandesha2/C module for Axis2/C I found it very difficult to cope with the Axis2/C engine internals when it comes to memory handling and scope management. For example you need to have a through understanding about life time and scopes of axis2_msg_ctx, axis2_op_ctx etc. It is good if someone explains about deployment model about timeouts, about good to know functions, how to reuse service client in your client application, about http_transport_info struct etc. etc. I will start working on a article explaining these as time permits.

Reliable Messaging with Sandesha2/C

2008-03-03T09:08:00.000-08:00

The reliable messaging implementation for Axis2/C web services stack is called Sandesha2/C. The architecture is same as the corresponding Sandesha2 implementation for Axis2/Java stack. This fits into the Axis2/C stack as a module plugin. I have been working on this for more than a year now and the existing functionlity is interoperable with the Sandesha2/Java and the Microsoft Indigo.
Currently Sandesha2/C is integrated into the WSF/PHP stack of WSO2.
These days I am writing some articles for WSO2 Oxygen tank about Sandesha2/C and WSF/PHP Sandesha2 integration work.

Amazon web services client using wsclient

2008-02-25T00:11:00.000-08:00

See my blog about amazoneclient which I am working on these days,

http://damithakumarage.wordpress.com/2008/02/22/amazon-web-services-client-using-wsclient/

Now the work on linux platform is almost finished except the --help option which is going to be quite exhastive. I will upload this work by the end of this week. After that, plan port this to Windows platform.

Soap Action and Addressing Action

2008-02-12T20:20:00.000-08:00

Here I have reproduced some excerpts from the specifications to understand the Soap Action and Web Services Addressing Action.

For a good understanding of how Axis2/C addressing work read
WS-Addressing in Action

CURL with SOAP

2008-01-18T22:17:00.000-08:00

curl is a software designed to deal with HTTP protocol. When it comes to REST, we could send request quite easily with curl. However , although it is not straight forward you could use curl for sending SOAP messages too. This method could not used for day to day use, but it is very useful when it come to testing. If you need to test a service, it is more or less the same request send to server. First you need to get soap request into a file (say echo.xml) and then send it to the service URI.

curl -d @echo.xml -H "Content-Type: application/soap+xml;charset=UTF-8 " 
http://localhost:9090/axis2/services/echo

An advantage with this method is , you could deal with HTTP related things very easily. Say if you need to send additional HTTP header with soap request, you could do it with "-H" option.

curl -d @echo.xml -H "Content-Type: application/soap+xml;charset=UTF-8" -H "User-Agent:Apache Axis2/C"
 http://localhost:9090/axis2/services/echo

and will be able to do modifications to SOAP payload quite easily. (Need to edit echo.xml file only :) )

Axis2/C, custom errors

2008-01-18T19:35:00.000-08:00

In this post I discussed about using custom errors in Axis2/C [link]. In order to define custom errors , used error block that is reserved for user needs. The usage demonstrated using modified echo server sample. If you think if you need more clarifications or see any point to improve, feel free to let me know.

Security What You're Looking for??

2008-01-17T03:21:00.000-08:00

Confidentiality and integrity of massages are very important when you do serious business on line. WS-Security comes for your help at this point. The WS_Security specification describes enhancements to SOAP messaging to provide quality of protection through message integrity, message confidentiality, and single message authentication.

How do you use these security mechanisms in your WSF/C web service/client?? Using Rampart/C is your answer.

Rampart/C is the security module of the Apache Axis2/C engine, which uses OMXMLSecurity as the XML-Security library. This comes as the integrated security module for WSO2 WSF/C. You can simply enable security in your web service with WSO2 Web Services Framework for C( WSF/C).

Here, you can find nice articles on Rampart/C.

WSF/C developer and user resources

2008-01-09T03:16:00.000-08:00

Here I posted about some resources for Axis2/C and WSF/C, developers and users. Any one can use those resource to get best use from WSF/C. In that post , I mainly focused on Axis2/C , and any one who interested in other components of WSF/C have some important information there too.

WSF/C Interoperability - CHECKED

2008-01-07T21:42:00.000-08:00

WSO2 WSF/C was successfully tested with Microsoft WCF /.NET framework web services in Microsoft Web Services Interop plugfest, last November. The session was very successful for WSF/C. Most of the WS-* scenarios were tested. WS-Addressing, WS-Security, attachments with mtom, Secure attachments with mtom and WS-RM are the major areas that were tested.

Embedding WSF/C

2008-01-06T07:03:00.001-08:00

WSO2 Web services framework for C has been integrated to three software systems as of now.

First the PHP extension, with WSO2 WSF/PHP.

Then with WSO2 WSF/Perl, the Perl Web services extension.

And the latest is WSO2 WSF/Ruby, the Ruby Web services extension that also works with Rails framework.

This means that WSO2 WSF/C has been integrated and embedded enough times to prove that it is portable and can be plugged in.

Anyone who uses any of the above frameworks happen to use WSF/C and in turn Apache Axis2/C, the open source Web services engine. It must be also mentioned that WSO2 WSF/C as well as all the other scripting frameworks built on that are also open source with the Apache 2.0 license.

Lazy to ask question on mailing list ??

2008-01-04T23:02:00.000-08:00

If you get WSF/C or Axis2/C related questions and you are too lazy to post it on a mailing list. We have our WSF/C forum ready to keep you up. Keep posting !

WSF/C and WSDL

2008-01-04T09:24:00.000-08:00

If you are a WSF/C user , you might wonder about the possibility of displaying WSDL for a particular service. Although we are far behind to generate WSDL dynamically , one can have static WSDL and display with "?" sign. All you have to do is have an entry in services.xml file and need to give full path to WSDL file.

<parameter name="wsdl_path" locked="xsd:false">/home/dinesh/echo.wsdl
< /parameter>

Then start the server and request WSDL file as follows.

http://localhost:9090/axis2/services/echo?wsdl

Mother of all Web Services Frameworks

2008-01-04T01:21:00.000-08:00

WSO2 Web Services Framework for C is the mother project of all the Web services frameworks like WSF/PHP, WSF/Perl and WSF/Ruby. They all come with Apache license.

WSO2 WSF/C in turn is based on Apache Axis2/C and the related family of projects.

So the power of the Apache open source model is driving them all. Thanks to all those developers who contributed code and fixes and those users who tested and reported bugs, we have a very strong Web services stack. Not only the C language but also many scripting languages has been made SOA ready, thanks to these valuable contributions.

Check out the Latest!

2008-01-04T01:16:00.000-08:00

If you have not already done, check out the latest 1.2.0 release of WSO2 Web services framework.

As always, many bugs have been fixed, thanks to the base project Apache Axis2/C
