Cannot initialize db after inserting a java.util.List

Hi, I've spent some time trying to figure this out without success, so I'm asking for much appreciated help. I have an entity class like this: class Test { private List<String> list = new ArrayList<String>(); } I can persist and retrieve the obj just fine using standalone program, but whenever I access the db through a servlet container I get this error: objectdb.java.util.ArrayList cannot be cast to com.objectdb.spi.TrackableSysType This happens during EntityManagerFactory initialization. #1 2010-12-24 03:05 Hi, I've spent some time trying to figure this out without success, so I'm asking for much appreciated he ...

Too many persistable types (>10) - exceeds evaluation limit

Hi, I am trying to evaluate and compare ObjectDB to other persistence solution for a project. At the moment I am trying to read in data written previously with JDO. As I am testing many frameworks and want to automate as much of the testing as possible I am using two persistence units for this and get a JdoDataStoreException: Too many persistable types (>10) - exceeds evaluation limit... Even though I define only 10 entites in the persistenceFile. Has this something to do with the fact that I have to persistence units? #1 2017-11-15 13:03 Hi, I am trying to evaluate and compare ObjectDB to other persistence solution for a project.

Problem upgrading

Hello! We are trying to upgrade from 2.6.3 to 2.6.6. Now our application throws an exception. It's generating endless log files. I had to turn up Xmx to even see it before the JVM crashes. (Our web framework tried to show the exception on the client) I did a full rebuild of the project. It's using the right version of the enhancer. There are no code errors. If I change everything back to 2.6.3 it starts to work again. Any ideas? Best Regards   Here's a part of the output: #1 2016-01-29 14:19 Hello! We are trying to upgrade from 2.6.3 to 2.6.6.
