Beansbinding

I’ve been doing experiments with JTables bound to database tables in the past. But I was not satisfied with the result to be honest. The pagination helps but there is still noticeable pauses each time a database query has to be issued. So I started looking into other possibilities. I come up with the idea of doing lazy loading and presenting some fake data until the data is really retrieved from the database, I did a small proof of concept and seems to work ok. ...

In my previous post I talk about JTable and JPA pagination through a custom TableModel. Now working directly with TableModel is not want you want to do, you want to use Beans Bindings because it means less manual coding and a lot of help from the IDE (like Netbeans). With netbeans you can easily bind a JTable to the result list of JPA query. But if that Query returns thousands of rows it’s going to be slow or unfeasible. And if you try to use JPA pagination (with Query.setMaxResults()) then you end with a table that will only show a subset of the rows. ...
