It is not possible to access the services.xml file. However, you can
access the content made available inside the services.xml file which will
be loaded into the service's configuration. Refer,

1. axis2_svc_ctx.h
2. axis2_svc.h

That is the API.

Same here. The axis2.xml will be loaded into the engine configuration. If
you can fill the right information into the right place, the engine will
be blind enough to believe that it has been there since the right
beginning. Your attention will have to be paid to,

1. axis2_conf_ctx.h
2. axis2_conf.h

In addition to that, to understand how the engine loads to itself the
configuration information, go through source found inside the
src/core/deployment sub directory. I know this sounds hard, but, it
wouldn't be a big deal to figure out what should be done.

If you want to write to axis2.xml and services.xml, you will basically
have to release any thread locks applied on them, and also, you will have
to use an xml writer. The engine only reads these at present and does not
write. For hot deployment, you will need only to read, but for hot
modifications, you will have to write. Feel free to introduce new API.
But, it is strongly advised not to change the existing API. I mean the
method signatures not the body here. Of course you can modify the body.

Please raise an issue on the Axis2/C JIRA so that other developers can get
involved too.

Regards,
Senaka

You can cut a chuck of bytes in a UTF-8 encoded document and paste it into a 
UTF-16 encoded document and the output document is still well-formed.
  c.. ISO-8859-10, ISO-8859-11, ISO-8859-12, ISO-8859-13, ISO-8859-14 and 
ISO-8859-15 support has now been added
  d.. Zero length Text node is now possible.
  e.. Ability to dump in-memory copy of text is added.
  f.. Various code cleanup, enhancement and bug fixes.
Below are some new articles related to VTD-XML

  a.. Index XML documents with VTD-XML 
http://xml.sys-con.com/read/453082.htm
  b.. Manipulate XML content the Ximple Way 
http://www.devx.com/xml/Article/36379
  c.. VTD-XML: A new vision of XML 
http://www.developer.com/xml/article.php/3714051
  d.. VTD-XML: XML Processing for the future 
http://www.codeproject.com/KB/cs/vtd-xml_examples.aspx
If you (or someone you know) like the concept of VTD-XML, think that it can 
help solve enterprises' XML processing related issues (particularly those 
related to SOA), and would like to directly influence and contribute to the 
development of the future of Internet, please email me 
crackeur@comcast.net). We are looking for open source software developers 
and project management people to take VTD-XML to the next level.
