BPEL: Beware the use of nested loops in a short running process

dan — Thu, 03 Jul 2008 15:43:25 +0000

One of the restrictions when dealing with a short running process is that it must always run within a single transaction. The implication is that the process must complete within the default transaction timeout window. On an application server, this is 120s. We had an issue where our Process Server was creating a large number [...]

WSDL Anti-Pattern: xsd:Any and xsd:AnyType To Encapsulate Future Changes

dan — Thu, 24 Apr 2008 16:54:44 +0000

The cousin to yesterday’s WSDL Anti-Pattern: The ‘Single XML String’ Service is the use of the XSD specification’s ‘any’. ‘Any’ literally means “any well-formed XML contained in this section is valid”. ‘anyType’ means “any valid XSD Type”. We can start to see the correlation between the Single XML String service and the use of these [...]

WSDL Anti-Pattern: The ‘Single XML String’ Service

dan — Wed, 23 Apr 2008 14:31:16 +0000

WSDL is a very useful technology. It allows service providers and consumers to agree on namespaces, operation names, the data to be transmitted in a request and the data to expect in a response. All very good things to know, all in a platform neutral way. Now, WSDL tells us what all the elements and [...]

Tip: Agree To Concrete WSDL Definitions before Development Begins

dan — Wed, 16 Apr 2008 17:17:24 +0000

If you are a provider or a consumer about to enter development on a web service, you should have an understanding with your counterpart of the WSDL that defines the service. It should be very well ‘baked’ and changes once development begins should be minimial. Major things like name spaces and object names should rarely [...]

Day two is in the bag, the B52′s are B-50-done. Perficient and MTS Allstream gave a session about SOA Patterns that I thought was today but was actually yesterday. Oops. Here’s the abstract if you have a time machine: TSP-2518 – Effectively selecting integration patterns Brent Legris, Perficient, Inc., Senior Technical Architect, Olivera Zatezalo, MTS [...]

The VETO SOA Pattern

dan — Tue, 01 Apr 2008 15:52:38 +0000

I’ve never been much of a patterns guy. I kind of always have the ability to apply common sense to a system and turn up something that is straight forward and makes sense. Periodically I get asked about what set of patterns I used to decide how a system should behave. To answer this question [...]

JDBC Adapter Export with events that comprise multiple rows

dan — Fri, 29 Feb 2008 03:08:33 +0000

At my client, we had a unique situation occur when integrating a database and an export for the WebSphere Adapter for JDBC. In a ‘typical’ scenario, a single row is written into a staging table, an SQL trigger writes this single row into the adapter’s event table, the adapter polls, converts the data into a [...]
