    How would one call a web service on another machine FROM lawson?  The call would need to be made in the background without opening a new window.   The web service can accept either a POST or GET request.  For this request, the response is not processed but future request probably would need to process the response. I think the xmlhttp request is the answer but have no documentation on it's use.

    I've seen a lot of posts on calling into Lawson web services from external applications but nothing going the other direction.

    Thanks for your help.

    Depends from where you are tyring to do it.  ProcessFlow Integrator has a Web Service node that is very easy to use and handles all the parameters, if it is with a web page within Lawson a http request will do it, as long as there are no authentication requirements it is not too difficult.

    Thanks. Do you know where I could find any documentation on it's use or is this just pure Javascript
    and would be called the same as it would on any other web page. Normally I would be calling this from
    an .ASPX page with an ASP script manager tag that would cause the browser to download the AJAX
    libraries to handle the call. Since Lawson is handling the page, I don't know that it is capable of
    downloading foreign script files. Does anyone have a document or pdf that shows the syntax for making
    this kind of call?

    Thanks again for your help.

    I failed to mention that we do not have process flow integrator.

    Well, now you have a reason to buy it :). Plus the ability to hook into databases and the file/data iterators.

    Thanks for using the LawsonGuru.com forums!
