I have IntelliJ IDEA 8.1.3. It has support for a hibernate facet/plugin which I have enabled. When I do this it recognises the HQL query strings but highlights in red all the objects and properties. I can't see how to get IDEA to be aware of my entities. I use spring+hibernate and annotated objects. I have no hibernate.cfg.xml just ...
Hello there, I'm fairly new to Hibernate and PostgreSQL, but so far it's going well, although I'm running into a problem now that I can't solve. I'm getting an error while filling the database on the very first operation (which is one transaction inserting or updating 1000 rows in the database). The error is: SQL Error: 0, SQLState: ...
Hi folks, I have what I would assume is a pretty standard setup...spring, jpa (hibernate) and I'm trying to add ehcache.

I am using Jboss5 and I'm trying to utilize Hibernate and Spring to load in a spring dao.

I am building an application under DDD architecture, thus I have implemented rich domain objects that can also be entities. These entities can also have full access to (injected) repositories that can do add & remove operations on other objects/entities. So far, this all works without any problems. But can side effects for objects/entit...

I have hibernate 3.3, c3p0, MySql 5.1, and Spring. The MySQL connections in my service calls are consistently being closed after ~39 minutes. The natural running time of my service call is on the order of ~5 hours. I've tried changing various c3p0 config, etc, to avoid the 39 minute cap. No luck. Is there a more direct, systematic wa...
Probably it is a basic question, but could not found the answer anywhere in the web. I am trying to use a second level cache (using ehcache) and just checked that some objects were being retrieved from database every time I tried to load them, the only difference was that I was not getting them by id but by a property that carries a SE...

At various points in time I need to replace the data in these tables with a newer version by connecting to the database externally. We are using postgres 8.3+ and hibernate 3.2.6. The external "update" process will be connecting to the db via PSQL...

I need to have multiple databases for different customers. How can I handle multiple databases with Hibernate? Are there any good examples how to do this? I could create Configuration object and then build SessionFactory, but that would create always a new session factory which wouldn't be very wise. EDIT: Now I can get hibernate Conf...
Hello, I am wondering if is possible to implement following domain model. Let's have a domain class which contains set of intervals (joda time).
