Let's not forget the fantastic evening parties featuring freshly imported Kölsch and the exhilarating Battle Pong Blitz game.

Using the Factory Pattern: How, When and Why

The Factory pattern and its relatives provide a way in which application infrastructure or frameworks can guarantee that a developer gets what they are asking for. This session covered the patterns themselves, how to implement them, and why you would want to (and not).

Our workshops:

In the workshops Mike Fechner and Daniel van Doorn showed:

Using the ABL HTTP Client for Fun & Profit
Most applications integrate with external systems, internal and external to the business. More and more of these use HTTP rather than something like SOAP to communicate. The ABL’s HTTP client has been available since OpenEdge release 11.5 and provides an easy way to make requests to these systems using standard HTTP. This workshop gave attendees an understanding of how to use the HTTP client for a variety of requests, using various standard data types such as JSON and XML, but also more exotic types like multipart or MTOM messages. It showed attendees how to build and make requests and how to process the responses. This workshop focused on making secure requests, at an API level (using login credentials, cookies and/or headers) as well at the network level using TLS/HTTPS. Troubleshooting and customizing the HTTP client will also be covered.

Great Power and Great Responibility: Writing Web Handlers
Web handlers have been available in PASOE since 11.6.0 and are an easy – for the ABL programmer – way of adding a REST API to an application. Web handlers give programmers many options, but they also require that the ABL code deal with most aspects of the request and response, including conversion from “HTTP” to “ABL” (or even “4GL” if you’re that way inclined) and back again. An application may have one web handler per business service, or just one for the application, or something in between. This workshop discussed how to decide on approaches for how many web handlers your application needs, how to write a web handler – covering content types, strategies for error handling and status codes, routing requests and more – and also covers topics like deployment and authorization.
