This message has been marked as the solution to the initial question of the thread.
Lennert,

Web services, like the rest of the web, are "stateless", meaning you can't count on anything being the same between requests to the web server. On a web site, you could use cookies or some other method to maintain state on the web server, but I don't know if that's available for SOAP. I think you will have to pass user and pwd to every method on the web service. Also, each method needs to be independent. You can't rely on SomeMethod1() to set properties that SomeMethod2() will use.

>The init-method writes 1 character to a file (additionally). Every time I call some method of loService an extra character is written. Is this just the way SOAP works? Every time you call it it initializes again? Then it is the wrong type of solution for me.I need the object to remember it is already instantiated and remebers it own properties etc. I expected it to behave the same as when calling the same dll locally:
>
>loService = CREATEOBJECT("ifundsmw2.ifundsmw2")
>? loService.SomeMethod1()
>? loService.SomeMethod2()
>
>but it doesn't.

>Maybe I need to make myself clearer: I want users of the service to log on to the service (something like loservice.logon(user,pwd)) and after that they can use the loservice-object to question a database, getting answers in xml.
