ObjectDb Supports Clustering of Servers?

As of now we are using Oracle + Hibernate + JPA , as Oracle is shared data there was no problem. ... my local DB it was too fast where as it is taking so much time to connect Linux Object DB. So I though Object DB is faster but ...

persistence.xml classes not respected by ObjectDB

Hi! I have the following persistence.xml. The problem is that ObjectDB loads all the classes in P1 (+ their embeddable classes). P2 is created properly, but P1 gets all entity classes (from P2 also). How can this be avoided, so that both P1 and P2 get just the classes that were specified to each? There is no place in code where P1 tries to access classes from P2, so it makes no sense. #1 2013-08-20 07:48 Hi! I have the following persistence.xml. The problem is that ObjectDB loads all the classes in P1 (+ the ...

How to add minutes to a Date with JPA2

Hi,  I have to sum to a date of minutes, and check the date obtained is greater than the current date. My idea is as follows: Calendar currentTime = Calendar.getInstance(); Date currenteDate = currentTime.getTime(); Expression<Date> dateCapture = root.get(Counter_.dateCapture); Expression<Integer> samplingPeriod = root.get(Counter_.samplingPeriod); Expression<Integer> delayMinutes  = cb.prod(samplingPeriod,3); //minutes to be added ... as an extension another date function that will return time in milliseconds representation, and you will be able to work with numbers ...

ObjectDB eclipse plugin

Hello, Creating an eclipse plugin from the downloadable objectdb.jar file DOES NOT work in the eclipse OSGi environment (at least that is my experience). Could we have a genuine eclipse plugin from ObjectDB that works? You already have a pluging that integrates Objectdb with BIRT, so it seems it should not be difficult. The downloads could now have both the eclipse plugin as well as the usual jar. Let me know what you think.   Thanks #1 2011-07-14 18:30 Hello, Creating an eclipse plugin from the downloadable objectdb.jar file DOES NOT work in the eclipse OS ...

Future JDO versions?

We are about to release our first product using ObjectDB (as a small embedded store), and soon hope to release a much larger product using ObjectDB (will need an OEM license).  What really interests us is JDO.  We have been using JDO for over a decade and have found it consistently a far better API than JPA, as all kinds of features that are optional or require special extensions in JPA products, (such as large query optimisation, storage of collections of non-entities and automated management of identity) are built-in to JDO.... for JPA, and could be added to JPA and JDO at the same time in a future version of ObjectDB. Same is regarding automatically generated ...
