NAV 2009, 2-tier and webservices

Hello everyone,

We're still on NAV40SP3 and we want to start using web services for a number of integration scenario's. Our vendor says that we can use NAV 2009 for this purpose, so I started to look into this. I found documentation that the 3-tier architecture supports the web services. We decided that migrating to this 3-tier architecture is not feasible at the moment.

Our vendor told me that the 2-tier architecture also supports webservices, but I can't find any evidence on this and after repeatedly asking our vendor, no documentation whatsoever is coming my way. So I turn to this forum :D Does anybody know if webservices are supported in the 2-tier architecture?

Thanks in advance and I'm looking forward to your reply.


Kind regards,
Bob Stanneveld

    As far as I know there isn't a 2-tier architecture for web services because the middle tier is the central processing unit for web services. You have to run a middle tier which is representing the service tier. In this instance you can have 2 services, one for RTC and the other for web services.

    Hi Egnaz,

    Thank you for your quick response. It's just as I thought. The webservices in the 2-tier architecture don't make any sense. I still wonder why our vendor say's that the webservices work in the 2-tier environment.


    Kind regards,

    It works. You do not need to use whole "3-tier" architecture. You will just use 2-tier for users and the webservices service to connect external applications. It only means that the objects used by the webservices must be able to compile for use in 3-tier. But in most cases it is not problem.

    And of course, for 2-tier you can use NAS and some webservice implementation (it is not problem to do it through external libraries).

    Hi Kine,

    Hi Kine,

    thanks for that. It was something new for me but I learned in the last few years that in NAV you never (can) know everything :)
