A brief introduction to JPA’s optimistic locking system as I understand it For performance reasons, the designers of JPA decided that optimistic [...] […]

While working on our business accounting software, I recently learned about a very useful class in glassfish from a friendly fellow on the glassfish users mailing list. This is the WorkManager, a class that allows you to add Runnable bits of Work for glassfish to run in another thread pool. I use this to perform independent [...]

Accidentally double-charged a bunch of credit cards this morning, had to clean up a big mess. Lessons: Learn about how JPA locking REALLY works, I thought I was getting serializable transaction isolation, in fact it’s optimistic locking.

Hibernate Annotations: @OneToOne with mappedBy and lazy fetch are dangerous! October 8, 2008

Today I ran into a very frustrating issue with hibernate and lazy inverse @OneToOne mappings.

Just when I thought the past would disappear October 2, 2008

Back then both of these sites were hosted on a cheap [...]
