What are the exception handling best practices in workflow services

Posted By:      Posted Date: May 22, 2011    Points: 0   Category :JQuery
What are the best exception handling practices in workflow services declared in xamlx.
I have created an application, the service layer of the application has Xamlx workflow services hosted on IIS. Workflow services are calling data services through custom activities to get data. Exception could arise either in the workflow service or in custom activities or data services might throw exceptions. What is the best practice to handle declared and undeclared exceptions in the service layer.
At the UI, I have an Asp.net web application.

Every self-respected programmer should include exception handling techniques. Sometimes your application will generate an error. Regardless of who was responsible for this error, the programmer or the user, it is up to the first to include the necessary exception handling techniques to keep his/her program from crashing. The .Net environment provides useful techniques for avoiding disastrous errors such as try-catch statements and user-defined exceptions.

Global Exception Handling with ASP.NET

After your global exception handler has done its work, you'll want to redirect the users of your website to a friendly page that tells them that something has gone wrong, and then provide them with customer support information as well as a link back to your web application's home page.

SQL Server 2005 Try and Catch Exception Handling

I'm pretty excited to see that there is some real error handling for T-SQL code in SQL Server 2005. It's pretty painful to have your wonderfully architected .NET solution tainted by less-than-VBScript error handling for stored procedures in the database. The big difference being the addition of TRY..CATCH blocks. Let's take a look:

Error while using exception handling block el 4.1


Hi Folks,


i am trying to use tyhe exception handling block of Enterprise library 4.1.

Workflow Services: Visual Design of Workflows with WCF and WF 4


The .NET Framework 4 makes it easier than ever to implement WCF services using WF. We'll demonstrate just how easy it is by modeling a long-running, durable and instrumented workflow based on a real-world business case without having to write any code.

Foundations: Workflow Services for Local Communication


This month's column describes how to use WCF for communication between a workflow and a host application in Windows Workflow Foundation 3. This knowledge should help developers with their efforts using WF3 and prepare them for WF4, where WCF is the only abstraction over queues (referred to as "bookmarks" in WF4) that ships with the framework.

BizTalk 2004: Automate Your Business Processes with Human Workflow Services and Visual Studio


BizTalk Server is an excellent platform for automating B2B and EAI workflows. Process-driven workflows send messages between machines and access data. Until now, such processes were very difficult to automate, but with the introduction of Human Workflow Services in BizTalk Server 2004, this class of workflow automation is a very real possibility. This article explains it all.

Error Handling: Throwing Custom Exception Types from a Managed COM+ Server Application


Exception handling semantics in .NET are based on type, so you can create custom exceptions that have their own properties and methods. In .NET, exceptions are first-class citizens, and since they're the built-in error handling mechanism, all .NET-compliant languages must support exceptions. In addition, COM+ services are available to .NET code as Enterprise Services, so you can leverage exceptions in your Enterprise Services design.In this article the author describes custom exceptions, throwing exceptions across COM interop boundaries, and working with Enterprise Services.

Error loading workflow services

Hello, I'm developing a service library using the new wf 4.0 and one of my requirements is that some activities have the ability to be resumed by a client, so i created a wcf resume service that could load a workflow definition and resume a bookmark of that workflow. One of the services i created was a flowchart that has a receive reply activites inside a sequence activity has a start point, after that i have another sequence that have another sequence, yes 2 sequence activities, and my custom activity that needs to be resumed by a client. The 2 nested sequence activites was a something i used only for testing, but if i had those 2 sequence activities nested i got an error when loading that workflow definition in my resume service: 'ObtemPareceres' is not of type 'Sequence'. When loading this instance you must ensure that the activity with name 'ObtemPareceres' implements 'Sequence'. The "ObtemPareceres" is my custom activity, and if i remove that second nested sequence everything works fine. Anyone has any idea of whats going where? thanksFrederico Regateiro
