Next week, after presenting at Jfokus, Peter Hilton will also present at the Scala Stockholm meet-up on 15 February.
Next week, on 14 February 2012, Peter Hilton will present Play Framework 2.0 at Jfokus 2012 in Stockholm. Jfokus is the biggest Java developer conference in Sweden, started in 2007.
On 3 February 2012, Lunatech hosted a Play!ground event at Paddy Murphy’s Irish pub in Rotterdam - an event for developers interested in the Play framework. Here are the slides from the presentations.
JPA (the Java Persistence API) sometimes does a little too much for its own good. Distinctions between managed and unmanaged entities or between save() and merge() are relevant when most objects stay in memory a long time, and are ‘synchronized’ with the database at different intervals during their lifetime.
In a Play! framework application, persistent data is rarely kept in memory for more than a single request. Hence an entity is going to be saved to the database almost after every time it is modfied. Because this is not the workflow JPA designers had in mind, sometimes JPA gets in the way.
By popular demand, we have arranged a bigger location for next month’s February Play!ground event, for Play framework users, because we have had close registration for previous events that were full. Instead of using the Lunatech office, which limits us to thirty attendees, we have booked a location with capacity for 150 people.
