Re: Is AXIS2/C what I need?

Michael Sutter Wed, 22 Aug 2007 02:48:59 -0700

Hello,

I tested axis2 with c++ and was not able to get it running. But Icommunicated with some one and he told me, that it is working.

If anybody knows how it goes it would be very nice to tell it me.

What I tried is to compile a axis2c service with g++. With some tricksthe compiling and linkings works. But the call of the service alwaysends in a segmentation fault.


Regards Michael

By your reply i can say over safe ground that i can use axis and/or axis2 (both 
for c/c++) in a production environment without surprises, am i right?

Well, another reason for stopping our trying axis was due to the difficulties 
we had installing it, hope you or any of the mailing list members can help... 
i'll be posting my experience tomorrow at work (i'm at home now), but what i 
recall is always having trouble with the AxisXMLParser.Dll thing. I haven't 
fully tried Axis 2 for C/C++, but I'd like to hear comments/recommendations on 
which one would be better to use.

Thanks

Carlos

Hi Frank,
It has to.. at our company we ceased researching axis due to it'sdevelopment status, but have been using gSOAP for most of our C/C++webservices, and of course, they all pack a wsdl with them ;) nowwhere that parser is being used I don't know, but I can tell for sureit does parse them.

Axis2/C also have the contract first model of development.

We had success communicating a webservice written in a z/OS serverwith a Windows XP C++ client which was built using gSOAP.

Axis2/C has proved to interop with .NET and J2EE with basic SOAP as wellas WS-* level.


Samisa...

Hope that helps

Thanks much for your replies. I had quite a bit of
experience with AXIS-J but not gSOAP or AXIS-c. Does
gSOAP come with a WSDL parser with APIs to allow me
traverse the various parts of a WSDL? In my
application, I do not intend to deploy just one web
services (so no code generation), I need to be able to
parse any standard WSDLs.

Thanks much.

Frank,

Hi again. Just to cover our reasons for using gsoap:

1. It is older software ... fewer bugs. Lower risk
for a production project.
2. We used it for an rpc wsdl, so nothing too fancy
as far as wsdls go.
3. Our legacy C++ software developers and
integration team knows almost
nothing about building C++ code with ant (they
dislike all things java).
4. Axis2 for java was not ready for production so
(at the time) we did not
consider Axis2/c.

Hi All,

I am trying to build a web service application

in c++,

and now investigate to see if AXIS2/c can

satisfy my

needs. Specifically, I have the following
requirements:

(1) The library supports common web services

standards

 like SOAP/HTTP/WSDL et cetera. I will use it to

build

 a web service client application (web service
 consumer).

Axis2/C can handle SOAP over HTTP. But there are

some TODOs pending in

WSDL space.

(2) It should provides a rich set of APIs for me

to

 traverse through a WSDL and make SOAP/HTTP

calls. In

 particular, I need a WSDL parser so that I can

parse

a
 WSDL (given the WSDL file or the URL)to get the
 definitions. I DO NOT NEED TO CONVERT THE WSDL

TO

 C++ code, just need to parse a WSDL to get the
 definitions, later on I will traverse the

parsed

 objects to get the services, operations,

messages

 and types (XML schemas) et cetera to build my

only

 datastore for a given WSDL. This way I can
 dynamically handle different WSDLs in my

application

 without generating the c++ code stubs every

time.

As mentioned earlier, there is a piece of code

written in Axis2/C called

woden, that can deal with the WSDL functionality

that you are looking for.

Unfortunately that is not in the main source tree,

because we could not

maintain it -  due to lack of contributors in that

space.

At some point, however, someone will again start

looking into that, at

which point you would have WSDL handling features.

(3) The library is in c++ and available for
multi-platforms, like windows, linux and unix et
cetera.

Axis2/C is a C library, that works on Windows,

Solaris, MacOS and Linux.

Please let me know if AXIS2/c is a good choice

to me.

and how it is compared to gSOAP?

I am not in a position to do a formal comparison

on Axis2/C vs. gSOAP.

However, here is an overview:
    - Axis2/C comes with Apache license, and gSOAP

comes with GNU license

    - Axis2/C is just two years old, gSOAP has

been around for much longer

    - Axis2/C is based on Axis2 architecture, an

architecture designed

to cope with extensions and addition of new WS-*

spec implementations.

You would have to refer to gSOAP site on their

architecture

    - Axis2/C already have full WS-Security and

WS-RM implementations,

to my knowledge, gSOAP do not have those specs

implemented fully.

(http://www.bloglines.com/blog/samisa?id=57)
    - Axis2/C has a comparatively simple

deployment model. You get

Apache2 and IIS modules with Axis2/C. If you are

using apache module to

deploy, it is one off configuration. But if gSOAP,

you have to configure

Apache server for each and every service that you

cant to deploy.

   - Axis2/C has the ability to support many other

transports. It

already support HTTP and TCP. WSO2 WSF/C has

implemented an XMPP

transport and one of the GSOC students is

implementing and SMTP

transport. To my knowledge, gSOAP only support

HTTP transport

HTH

Samisa...

Thanks very much.
