JBoss 7.1 and EAP 6 support

I understand that keeping up with a new version can be difficult. Having said that, JBoss 7.1.1 Final was released in early March and Enterprise Application Platform (EAP) 6, the fully supported version by RedHat which is based on 7.1, has been released recently. I would really like to use ObjectDB since I believe that I will need the performance gains you show. Is there a plan to support this version of JBoss? I would also like to ask when but I know timeframes are not really known in advance, let me just state that my project will need to go live in about 4 weeks. ... are not really known in advance, let me just state that my project will need to go live in about 4 weeks.

Embedded Database Replication

As we all know, embedded databases out perform server databases on every occasion. The problem with embedded databases is that theyre difficult to scale. If I were to create an entire enterprise web application within a single jar file using embedded tomcat and embedded objectdb I would run into problems trying to cluster the data. Is there a way to cluster embedded objectdb? Perhaps some kind of external replicator application that can be used by server administrators to ensure replication is optimal and healthy?... to scale.

Performance problem

Hi, we have a strange performance problem with ObjectDB 2.5.3_01 and JBoss 7.1.1. We have two ObjectDB databases on one ObjectDB server. Production database is running 5-10 times slower than test database. Their size and number of records are almost identical. When running production database in separate test environment its speed is very good. We did a performance analysis on our 2 linux servers one running JBOSS and other running ObjectDB. - CPU utilization of JBOSS server is max 5-10% (per core)... records takes 30ms which we think is very good. In our web application this behaviour gives aprox 10-13 s of refreshing a data table ... to fix it. regards. Project.zip edit ...

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.... in hosted mode. It might be related to the embedded Jetty web server since a previous report indicated that the exception doesn't happen ... If it still happens - could you please upload a simple GWT project that demonstrates the problem? ObjectDB Support ...
