[ace-users] COM environment in ACE

[Sreejith]

Hi,
Does ACE provide a COM like environment for its users to
create component based software architecture where in components can
be plugged-in to add functionality and can connect it with other
components using the built-in features? I have worked on XPCOM where
I can define interfaces in an IDL file and compile it to generate
header files and implementation .cpp files (stubs). Do we have some
thing similar to this in ACE for component based sw development? This
helps to use the pattern already available in ACE to be used in the
components for application development and communication needs.

Thanks,

Hi Sreejith,

Please see the Component-Integrated ACE ORB (CIAO), which is
described at

http://www.dre.vanderbilt.edu/CIAO

and which can be downloaded from

http://download.dre.vanderbilt.edu

Thanks,

Doug

Hi,
Thanks a lot. I started going thru the CIAO documentation
and I think this is what I want!

Thanks,

Hi,
One more quick question. Can ACE handle 'data' in XML format?
Do we have built in Parser libraries in ACE? I am trying to implement
some thing like 'XMLSockets' where in every one (components) in XML!

Thanks,
Sreejith

Great! We're making lots of improvements to CIAO these days, so please
keep an eye out for forthcoming releases.

Thanks,

Doug

ACE does indeed have an XML library (ACE_ROOT/ACEXML). We recommend
using xerces, however, since it's more complete and better maintained
than ACEXML. We use ACEXML in CIAO, for example.

Thanks,

I am evaluating ACE for embedded devices and I don't think I can use
xerces (I guess it's from Apche project?) as it's a bit heavy! I will
look into ACEXML. Also I got a very tiny xml parser here:
http://www.applied-mathematics.net/tools/xmlParser.html
I think it's really handy for embedded devices.

Thanks a lot,

Hi

That is, we use xerces in CIAO.

Do you mean ACEXML is a wrapper for xerces lib? OR Do you mean xerces
can be used for embedded devices?

Hi,

We use xerces for CIAO (thanks Will!), but it's not optimized for embedded systems. If you are using XML for embedded systems, therefore, you may want to go with something that's smaller in size than xerces.

Right. One option might be:

http://www.codesynthesis.com/products/xsde/

which is a parser optimized for embedded systems, but is only free for GPL
projects.

You may also want to look at: http://sourceforge.net/projects/tinyxml/

Its a very light-weight XML parser available under zlib/libpng license (GPL).

Thanks,
