Hello

I have a service that inputs are the users in a Role or Group. So, I don

I think, in a general case, and regardless of using webMethods or not, trying to get the list of every user having a role is not a good practice. There may be thousands of them, and the procedure may be complex (e.g. recursive, check duplicates) and time consuming. So I would try to avoid this when possible.

In many cases, instead of this it suffices to be able to ask whether a particular user has a given role or not. I would first make really sure that the service needs all these users.

However, if you really need that, I think there are some web services provided by MWS among the ones described at webMethods Advantage that may help you. I think there was also a documented Java API, but I can’t find it now.

Hope this helps
