[Hibernate] Designing for Database Portability
Morning all, I have a project starting up that will be initially deployed on DB2, but will later be moved to Oracle. I'm curious as to what are some portability practices that I can employ in order to ensure that I can change databases without having to change my HQL statements. Ideally, I would like to just change the JDBC connection info and the dialect and be done with it. Thanks for your input. Regards, Nick Heudecker --- This SF.net email is sponsored by Dice.com.

Re: [Hibernate] hibernate xdoclet plugin & ehcache
If nobody else steps up, I'm willing to take this on. I've done some other XDoclet hacking recently and it's not too bad. However, I haven't touched any of the XDoclet 2 stuff.

[Hibernate] [ANNOUNCE] 'Introduction To Hibernate' Updated
Hi, I'm currently in the process of updating my 'Introduction to Hibernate' article to reflect the changes in 2.1. I have also converted it from PDF to HTML to make it more accessible. The updated article can be found here: http://www.systemmobile.com/articles/IntroductionToHibernate.html The intro page is at: http://www.systemmobile.com/articles/hibernate_intro.php Gavin, et. al: Would it be possible to have the following pages updated to reflect this new location? http://www.hibernate.org/152.html http://www.hibernate.org/78.html Thanks for your time. I'm still working on my HQL article, which I'm hoping will be completed shortly. -- Nick Heudecker System Mobile, Inc.

[Hibernate] Suggested Patch To Query Class
Morning all (EST):
I would like to make the setProperties(Object) method in the Query class a bit smarter
by adding a patch looking something like this:
public Query setProperties(Object bean) throws HibernateException {
Class clazz = bean.getClass();
String[] params = getNamedParameters();
for (int i = 0; i < params.length; i++) {
String namedParam = params[i];
try {
Getter getter = ReflectHelper.getter(clazz, namedParam);
Class retType = getter.getReturnType();
if (retType.isArray() || retType instanceof
java.util.Collection) {
setParameterList( namedParam,
getter.get(bean) );
}
else {
setParameter( namedParam, getter.get(bean), guessType(
getter.getReturnType() ) );
}
}
catch (PropertyNotFoundException pnfe) {
// shouldn't something be logged here?
}
}
return this;
}
Thoughts on this?

[Hibernate] Suggested Patch To (Abstract)Query Class
Sorry for the resend, but were there any thoughts on this, or should I request an
enhancement through JIRA?

Re: [Hibernate] Hot redeploy issue in Tomcat
Another way to solve this is to tell Tomcat not to serialize the session data when shutting down. Granted, this may not be optimal for your particular environment, especially for a hot redeploy. Here's how you do it: The Manager element does the trick. This has been tested with Tomcat 4.x and 5.x. Gavin King wrote: AFAICT, it should be the application's responsibility to ensure that it bootstraps Hibernate *before* the session is deserialized. Then the lookup would be successful. Christian Bauer wrote: We have problem with "SessionFactory not found: null" messages when Tomcat reloads a servlet context. This happens when you have a disconnected Session in your HttpSession, which is then serialized/deserialized while the classloader is restarted. This breaks the internals of Hibernate, as Hibernate tries to lookup the SessionFactoryImpl for the Session in a singleton HashMap in SessionFactoryObjectFactory on deserialization. Note that this is not a problem usually in application servers, where the lookup can be made using JNDI.

[Hibernate] Bug HB-1202
All: Bug HB-1202 (http://opensource.atlassian.com/projects/hibernate/browse/HB-1202) has become a show-stopper for me. I've dug around the source and I'm not sure of the best way to fix it. Can someone provide guidance on resolving the problem with saveOrUpdateCopy? I don't have any problem fixing it; my problem is finding it. :) Thanks for your time.

I'm not a committer, but I prefer 'deferred'. On Mar 8, 2005, at 10:21 AM, Michael Gloegl wrote: I think we made a big mistake by re-using the word “lazy” for attribute-level lazy fetching. People think that will disable proxying. Does anyone know another term we could use?
