ECL .NET Remoting

Andrea Morandotti

Good morning.

 

I was taking a brief look at the SDK ECL v9 documentation. There is a diagram which shows that the recommended way to interact with the BPM engine by means of ECL is, for third party applications, the ECL.WS web service.

 

However, if the v9 standard web client alone were to interact with the engine, the diagram shows that there is the possibily to bypass the whole ECL.WS layer and interact directly with the engine using .NET Remoting.

 

Since this is exactly the scenario of the process I'm developing (that is, a standard BPM v9 process with no use of third party applications), I was wondering how to invoke actions using ECL and .NET remoting alone.

 

If I got it right, the MetastormOperation class is used to interact using the ECL.WS, so what classes should I use if I wanted to  invoke actions using .NET Remoting alone?

 

Thank you,

If web services is an option instead of remoting, you could set up a service reference endpoint and consume the service from code.

 

The .net proxy classes that are generated will give you everything you need to communicate to the engine remotely. The object browser works best for inspecting the proxy classes, they are pretty self explanitory

 

The web service is Http://<engine server name>/ECL.WS/Service.svc. It may need to be installed as an option, I don't remember.

 

Example Code:

 

MBPM92Test.BPMService.ServiceClient BPM = new ServiceClient();

            FormField[] logindata = new FormField[] {
                new TextField() {Name = "username", Value="<valid user>"}, //where valid user is a user that can be authenticated in your system
                new TextField() {Name = "password",  Value= "<password>"} //password. You can use encrypt classes to send plain text password or use the string from euser table
            };

            ServiceSessionState session = BPM.Login("WEB;", 0, "", logindata);

            
            ListResult list = BPM.GetList(session, ListContentsType.Blank, new ListFilter(), "", "", 1, 1);

            

            BPM.Logout(session);
