Hi all This is mildly OT, so please ignore unless you're interested in and work with PostgreSQL via JPA/Hibernate/EclipseLink/etc in a desktop app setting. Ages ago, I asked here if others were using JDBC directly to access Pg from their java apps, or if they were using an ORM. I sought advice. Many suggested that an ORM was a strongly preferable option, and partly as a result of that advice I ended up using the JPA interface (with Hibernate powering it) for my database access in my Swing app. I've now concluded that, while it seems great on the surface, that approach is absolutely awful, because of issues with detatched entities, lazy property fetching, and the need to run database work on a non-EDT thread to avoid UI stalls/freezes and repaint delays. More details here: http://soapyfrogs.blogspot.com/2010/07/jpa-and-hibernateeclipselinkopenjpaetc.html Anyway, since folks here advised me to go for an ORM like Hibernate, I'm curious: How do you handle the need to avoid blocking on database access in your Java GUI apps, while lazily fetching properties of entities to avoid downloading half the database whenever you query it for anything? -- Craig Ringe
