Explorer

Hi,For last few days I was refactoring my application from standrad ORM aproach to ODB. Everything is fine for now, but I have a question about Explorer.

Failed to enhance dynamic type

Hi, We are trying to enhance a class with OSGI Weaver using the JEnhancer.THIS instance as a class transformer. Works very well except for some entities, i.e. we do have an entity which has: @Override public String getQubletHeadingMain(LanguageContext context) This is a simple implementation of our custom interface and should of course, NOT be enhanced. Yet, we get an error due enhancing: Failed to generate dynamic type com.quasado.galaxy.foundation.api.language.LanguageContext #1 2011-11-16 08:41 Hi, We are trying to enhance a class with OSGI Weaver using the JEnhancer.THIS instance as a class transf ...

Retrieving Metamodel without connection

Hello! I use Spring Data JPA. It uses the Metamodel to create repository beans. This triggers a connection to the ObjectDB server. It happens on every start of the Context. If it fails the application isn't available at all. I had the situations multiple times that my database server took longer to boot after a power outage than the tomcat machine. This leads to an unusable application until i restart tomcat. #1 2012-08-15 16:29 Hello! I use Spring Data JPA. It uses the Metamodel to create repository beans. This triggers a conn ...

InternalException during producer/consumer scenario

Hi, I'm trying to use objectdb in a producer/consumer scenario. Producer threads put message objects into a table while consumer threads remove the objects based on age, priority, etc. There are 2 main motivations for using objectdb for this purpose rather than a queue or similar data structure: 1) The consumer can select the "next" object based on a range of potentially complex criteria. 2) The number of objects produced can be potentially exceed available memory so can be held on disk within the objectdb file. Bug Version: 2.2.0 Priority: Normal Status: Fixed Replies: 2 Type:  Bug ...
