3. How to avoid loading Drools and Hibernate classes seamframework.orgHi, I'm having an issue that only became obvious with the last Weld 1.1.3.Final release which changed the log level for classloading problems: On container startup, several ClassNotFoundExceptions are logged, due to missing Drools and Hibernate classes. I don't use database persistence nor transactions, so I don't have hibernate in my classpath (my app is running on Tomcat 6). |
4. Hibernate and OSGI : ClassLoader forum.hibernate.orgHi, I'm developping an application which will use OSGI. The OSGI bundles will contains entities.

5. concreteQueries() in QueryTranslator.java - class load prob. forum.hibernate.orgIt seems like the concreteQueries(...) method in QueryTranslator.java is trying to load classes of values specified in the IN(...) clause and sometimes even trying to load table columns as classes.

9. Can we load the collection of a collection of a class? forum.hibernate.orgNo, you can't use "fetch" for collections twice in a single HQL query. Imagine what kind of join and result set would be produced. With your "fetch b, fetch c" query you'd get a product/cross join, which would retrieve a huge result set (really huge). Hibernate will then throw away most of the data (distinct style) to flatten this big result ... |
