Hi! I've been trying to get Glassfish 4 (Java EE 7) work with ObjectDB the whole day. It seems to be an error. The same code (adapted to Java EE 6) works perfect in Glassfish 3.1.2.2. I attached the samples as NetBeans projects, so that you could check easier. 1 for GF3 (6) and 1 for GF4 (7). Thanks! ...

Explorer in 2.3

First, the new Explorer in ObjectDB is fantastic! This is exactly what we've needed - an easy way to do ad-hoc JPQL queries and navigate through the results and even make small changes to primitive data and Strings. After playing with it for a while, here is a list of additional features I'd love to have: 1. Export of selected data: a. Simple - Select a range of cells or a column header and copy text to the clipboard or save to a file (csv, html, etc..).

Vacuum - Reclaiming Unused Space In Odb

I was curious if you could assist me with a challenge we are having with our objectdb database.  Our odb files are about 50Gb in size and are written to about a million times a day with both adds and updates.  This is creating a lot of unused space in the database that we are wanting to reclaim.  Other database vendors provide a vacuum process to allow dumping a database to a flat file (basically a sql dump) and reload.  Is there a capability in ObjectDb to provide a vacuum?  The online backup feature appears to copy the dead space as well so isn't performing... daily backup in case of a disaster (since it is more up to date).
