Felix, rollback exception, error 613

#1

Hello, i have a problem under felix osgi environment. I tested both 2.6.0 & 2.7.5 versions.

I can begin, persist and commit once, but not twice; even after framework restart. I need to delete my database file.

I joined my jee/bndtools workspace. I needed to change the classloader to properly get objectdb working under my osgi framework.

I have absolutely not any error under non-osgi environment.

 

Sorry for the two different messy stack traces :

To solve the class loader conflict you have to set the current thread class loader to the class loader that loads your entity classes, before accessing ObjectDB:

Thread.currentThread().setContextClassLoader(MyEntity.class.getClassLoader());

ObjectDB - Fast Object Database for Java (JPA/JDO)
