I want to call Aveksa server from Different domain using web service call .
I know aveksa can invoke webservice to perform some action but either way how it works
Please let me know how can we achieve that .
There may be a question here about the DNS server as well. If there is a new domain registered for the Aveksa server, it would also need to be listed in the DNS server being used by the inbound service attempting to make the call into the Aveksa box, otherwise it wouldnt be able to resolve the name to the correct ip address. That, or ensure the the invoking server has a local resolution (eg. Host file entry for the Aveksa server if it's a windows box). However, as Venkata mentioned above, the Web services on the Aveksa box need to be enabled first and foremost.
What do you mean with a different domain? As in a different network zone, separated by a firewall. And what is your use case here as there is multiple ways of looking at your question and also multiple solutions.
Via L&G (Aveksa) can handle web services, it uses collector / connector agents to be placed in different network zones so depending on your use case a solution can be defined
Have you checked Admin->WebServices. It has options to turn the web services, set the IP's from which web services can be invoked, list of web services supported and how to invoke each service.
