RE: Axis, Spring and Hibernate
This looks like a Hibernate issue, so you may want to move this thread to the Hibernate forum. Some hints: - When you open a new Hibernate session you need to re-attach your cached objects to this session before using them. - Use Hibernate.initialize(Object), Session.refresh(Object), and Session.saveOrUpdateCopy(Object) methods Regards.

RE: Axis, Spring and Hibernate
What if you persist the session factory? Opening a session during each start will mean you will have to load the hibernate config properties each time (unless ofcourse spring does something for that)...This (persisting the session factory and loading the config properties only once) improved my server's performance a little... De-serialization does ofcourse take some time - but I wasn't actually able to measure the amount of time taken just for the serialization/deserialization...that would have given a better picture...

RE: Axis, Spring and Hibernate
If you are using hibernate-style beans (that is, collections are represented as sets/bags), you can set the option for "lazy loading" - in which case when you are retrieving one object, hibernate will not retrieve all the children unless asked to do so. This will reduce the time for mapping the relations and their children back into relevant objects. I have a similar problem because I am using Axis-generated stubs (which contains arrays for collections - and this rules out the possibility of lazy loading)...

Re: Axis, Spring and Hibernate
Oops sorry i sent me message but i don't finish. Do you use the lazy initialisation ? I think no. So can you use it. The Hibernate Lazy mode will permit you don't load all the Hibernate graph in memory but just the necessary tables. When this option is not aactivated Hibernate load all the table when there are relationships between them.

Re: Axis, Spring and Hibernate
I am using Hibernaete in my current project with Axis too. It's not an Axis issue but just a Hibernate trouble. You have to investigate in the Hibernate Forum. 20 minutes for executing a queries it's not possible. My databases contains 32 tables with so many relationships and so many tables are full. My queries don't spend a lot of time as yours.
