How to: create a new component with Talend Open Studio

Yesterday I was searching for a good tutorial in order to learn the basics of component creation with Talend Open Studio (I needed to do a custom scheduling of reports, and Jasperserver simply wouldn't let me do it).
Check out this link:

In just a couple of hours, I was able to understand the the basics and I managed to create my very first component. Kudos to the author, it's pretty straightforward!

Querydsl

Yesterday I attended a Spring Data Webinar, talking about the latest updates about JPA, JDBC and REST support.
In particular, Spring JPA added support for Querydsl predicates and type-safe JPA queries. Being a JPA user (but not a Spring JPA) I didn't know about this framework, but I find it particularly useful :)
