Querying error - java.lang.ClassCastException: com.objectdb.o.STV

I'm getting the ClassCastException below when querying objects. As yet I haven't been able to track down the exact circumstance in which it occurs - saving and querying objects works fine on attempts to recreate - but presumably at some point an object gets saved which objectdb doesn't like. Any pointers as to what is wrong or approaches to investigate further would be much appreciated. Bug Version: 2.0.5 Priority: Critical Status: Fixed Replies: 6 Type:  Bug ...

problem with lazy loading - unittest project attached

hi, i'm still testing objectdb together with spring-data-jpa. i made a test which should simulate 4 requests 1. save entity 2. read an existing entity, add onetomany relation 3. read an existing entity, add another onetomany relation 4. read entity, get relations. i have the feeling this is not the optional way to test this, because of the differnt transaction behavior. the test is not transactional, but the spring repository methods are. #1 2011-05-04 05:32 hi, i'm still testing objectdb together with spring-data-jpa. i made a test which should simu ...

ObjectDB 2 JDO Manual

The new ObjectDB Manual describes how to use ObjectDB 2 with JPA. An additional manual that focuses on using ObjectDB 2 with JDO can help JDO users. But since writing a new manual and then maintaining two similar manuals, one for JPA and the other for JDO requires sufficient effort, this will be done only if there is sufficient demand.   Documentation Version: 1.04 Priority: Normal Status: Active Replies: 8 Type:  Documentation ...

Speed of queries that return many objects

Hi, I have a DB of 146MB - with 1_000_000 elements. Loading the contents (objectDB query in java) takes about 10sec. I am using a recent MacBook (SSD blabla - disk I/O speed is about 400MB/sec - according to blackMagicTest app for mac) - so I was expecting the query to take less than one sec (146/400 = 0.35sec.. + some overhead). I was wondering if this kind of speed is "normal", or if this is something I should investigate. Thanks EKK #1 2015-08-29 21:10 Hi, I have a DB of 146MB - with 1_000_000 elements.
