I've written up a tutorial covering setting up and using Hibernate, Spring, Middlegen, and XDoclet together. I wasn't sure if this is the correct place to post this or if I should post it under a different forum. Anyway, the link is:

Great, glad to hear people are finding it useful.

Nice tutorial. I have been meaning for some time to create better intro-docs for Middlegen / Hibernate. Alas time :-(. Your tutorial will help quite a few people i'm sure.

I been looking for a Spring/Hibernate Tutor Thanks!

Hello,

Been going through the tutorial and I came to a grinding stop. When I reached the 'Using Middlegen' part I encountered an odd thing. When I ran the ant script for middelgen (ant middlegen) I got a message (see below) that I was to wait for the process to read all tables. Well, I have been waiting a long time and nothing has changed. I still haven't figured out what it is that I'm doing wrong.

Any suggestions?

Thank you

Flauel,

That process usually only takes 10-15 seconds at most on my machine , a P4 2.4Ghz. I'd suggest stopping/restarting HSQL and Middlegen. Additionally, make sure you have the database setup correctly, the HSQL server is running and check that you're running HSQL 1.7.1 (not a newer version).

Cheers,

I was running a newer version of HSQL (hsqldb_1_7_2_RC_6a).

Thanks

Hi Tyler, I've found a little mistake/inconvenience in your applicationContextFactory.

The ClassPathXmlApplicationContext isn't a single instance. For your tutorial this works fine, but as soon as you retrieve different beans from the applicationContextFactory, it generates new ClassPathXmlApplicationContext objects resulting in multiple sessions being opened, etc.

I've had some problems with this, since after following your helpful tutorial, I used your applicationContextFactory again in my own project.

Kind regards

Peter

Peter,

That's really funny, because I literally JUST fixed that last night. I didn't write that code though, it was developed by Richard Hightower (rhightower@arc-mind.com). I converted the version I'm using to return a singleton instance. If you'd like I'd be more than happy to post the modified code, just a warning, I haven't cleaned it up/refactored it.

Cheers,
Tyler

P.S. Thanks for the feedback.

fear my psychic skills :)

About the modified code, I've written my own singleton this morning so it's not really necessary.

This is another hibernate tutorial split in two parts. It starts with the basic set up in eclipse along with screen shots
