Hi, I am trying to persist a class which is extended from an generic class - but fields declared inside the generic class are not persisted - is that expected? I assume it can be done b/c this field can be recovered after serialisation/deserialization. Here is an code to demonstrate the problem

Cloud HIMS is a JSF/JPA (EclipseLink 2.3)/MySQL application designed to capture data in Health Care Centres across Sri Lanka. We've recently migrated to ObjectDB to improve performance. Despite the migration, we're experiencing general performance issues across all transactions. As requested in

I'm trying to use sequences to set field values in JDO.  I want to do this in XML metadata to avoid use of annotations. This is an example of what I'm trying: When the code is run I get the message:  No definition of generator 'audit_seq' (referenced by field com.spiffymap.sealog.model

Hi ObjectDB team, we are currently investigating performance issues that affect some of our customers. Unfortunately, we are not yet able to reproduce issues in a test case, so we rely on reports and log files from customers. During internal analysis and discussions, we had some general questions

about it, that just defining the interface is not generally enough to define the persistence, 2 things

Hi  I was trying to enhance some of my classes and I got an error :  Failed to generate dynamic type com.package.RootContainer (error 361) It seems that all dependent classes are on the classpath , so what is missing or how to recognize what is wrong with that class ?? thanks in
