Hi all,

Openser works pretty well as Presence Server, but on this development stage (version 1.2.x) the communication with XCAP Server is done via mysql (xcap_xml table). The integration with XCAP-Lite works this way and works Ok.

However, SER has a library with XCAP-Client interface and we have started an integration of that library on the presence module of Openser. With this standard approach becomes possible the integration of the Openser Presence Server with, not only the XCAP-Lite, but also with others XCAP Servers, e.g., OpenXDM (https://openxdm.dev.java.net/).

To have this integration accomplish get into the following steps:

Libxcap Instalation:

tar xvzf ser-2.0.0+cvs20070315_src.tar.gz

cd ser-2.0.0+cvs20070315/lib/cds/

make install

cd ../xcap/

make install

export LD_LIBRARY_PATH=/usr/local/lib ( execute before starting openser)

Run the attached patch:

cd openser-1.2.x (openser’s root)

cp ../xcap_interface.diff . (Copy the patch to openser’s root)

patch -p1 <xcap_interface.diff (apply the patch )

Compile Openser, or if it is already compilied, just compile and install the presence module:

make modules=modules/presence modules

cp modules/presence/presence.so /usr/local/lib/openser/modules/

Add the XCAP configuration parameters on the Openser configuration file (openser.cfg):

“...

modparam("presence", "xcap_server", "http://x.x.x.x")

modparam("presence", "xcap_root", "xcap-root")

modparam("presence", "xcap_app_usage", "org.openmobilealliance.pres-rules")

modparam("presence", "xcap_document_name", "presrules")

modparam("presence", "xcap_auth_username", "openser")

modparam("presence", "xcap_auth_password", "openserrw")

...”

The integration was done with the following versions:

openser-1.2.x-svn-20070517-221101.tgz (http://www.openser.org/downloads/snapshots/openser-1.2.x/)

ser-2.0.0+cvs20070315_src.tar.gz (http://ftp.iptel.org/pub/ser/daily-snapshots/testing/)

With this modification, when the Presence Servers need to consult a client’s pres-rules it can do a XCAP Get instead of a MySql Query.

This approach is closer to the OMA Presence SIMPLE + OMA XDM standards.

Try it, test it and give us some feedback about it. If you have difficulties on the installation or configuration please contact us.

Best Regards,

Toni
