I am new to hibernate. I am using resin, hibernate with annotation.

I found problem that my first query take too much time to get data from database. The reason I found is that when first time I hit the application first page the hibernate bind all the annotated classes, verify named query etc and then after these work it get the data from the database. After this first hit query the other queries did not take much time as first one. I want to reduce the first query time by binding all annotated classes at compile time.

How to bind all annotated classes at compile time???

Please help me in this problem.

I don't think Hibernate (or JPA) support compile time binding. The binding is performed when you create the Session (or EntityManager) factory as at that time you provide the configuration details. If you haven't done so one of way speeding up the binding process is to tell Hibernate in which classes to look for entities. This way Hibernate doesn't have to scan all class files on your classpath looking for annotations.

thanks for your reply.

the thing is that i did not understand why hibernate search for the all classes even if i told the mappings in hibernate.cfg.xml.

also please let me know how to tell Hibernate in which classes to look for entities??

Try setting the property

hibernate.archive.autodetection="class, hbm"

or if you use XML configuration

<property name="hibernate.archive.autodetection" value="class, hbm"/>
