Hi people,

I am trying to build web services (VS 2005) using the Adapter pattern.

As suggested by OTIS in a thread (http://www.llblgen.com/tinyforum/Messages.aspx?ThreadID=6728&HighLight=1), I have enabled the schemaimporter task in my LLBLGen project. (I could not find the webservicehelper generator task though).

I am through with the implementation of the service and am able to test the results in browser through the asmx file. However, when I try to access the web service by adding Web Reference to a CLIENT project, I face the following two problems: 1) Even though I return EntityCollection from my webmethods, the proxy generated for the service has DataSets as the return type. I would prefer having the EntityCollection as the return type. 2) If I decide to go ahead with the DataSet return type, I still have a problem. Even though my service's webmethod returns a collection with objects in it(I tested this by debugging and also in browser), the dataset that I receive through the proxy doesnt have any Tables in it.

I have also gone through a few other threads: http://www.llblgen.com/tinyforum/Messages.aspx?ThreadID=2913&HighLight=1 http://www.llblgen.com/tinyforum/Messages.aspx?ThreadID=145&HighLight=1 http://www.llblgen.com/tinyforum/Messages.aspx?ThreadID=4973&HighLight=1 http://www.llblgen.com/tinyforum/Messages.aspx?ThreadID=4429 http://www.llblgen.com/tinyforum/Messages.aspx?ThreadID=6728&HighLight=1

But I couldnt find solution to my problem. I am not sure if I am missing anything.

Can anyone, please let me know where I am going wrong? If somebody could list the steps precisely (for making web services with LLBLGen work) that would definitely help a lot.

Thanks!

First question you have to ask yourself is why web services and not remoting? If you want to make the service available to non .net applications (and thus using a web service approach) then you are better off passing only simple data types and not collections.

Well mihies,

The consumers of my service will consist of .Net as well as non.Net clients. Hence, I have to use web services. At the same time, I would like my clients to receive entities and not DataSets. I am not sure whether this is possible for non.Net clients. But there must be some way for the .Net ones.

This is discussed in depth in the documentation. Please see: Using the generated code: XML Webservices support

I had this working with adapter classes generated in v2, then I switched to virtually the same classes generated in v1 and I can't get it to work anymore. Is there something inbuilt into the adapter classes that triggers the schema importer. I logged all the calls made to it and none are even for my web services namespace.

I have a few methods that accept an int and return a boolean, so I guess that what their about. What's going on with my entity classes and EntityCollection?

Thanks!

I missed out that part of the documentation. I ll have a look at it.

In the mean time, I am busy with another thing: http://www.llblgen.com/TinyForum/Messages.aspx?ThreadID=7726

Keeping you people busy.
