Hi Danny,
Nice to know you.
Nowadays, I am working on one my freelance project (a clinic website) and another project of mine (ebook management system). Actually, I kinda confuse to decide whether I have to use NHibernate or iBatis for both of them. Last year, I used iBatis for my previous project. But, I refer some people said that NHibernate is better and faster than iBatis.
All I know is that iBatis can use Spring for its Business Layer, and UIP as its presentation layer.
I try to find out if NHibernate can do the same thing like iBatis. I mean, can I use Spring for Business Prosess Layer, and if I can use Spring, then How?
And can I also combine UIP with NHibernate? And how do I manage to do this?
Thanks for your tutorial. And I’ll be waiting for your response.
Keep Writing!

Very good tutorial although it is a bit annoying that when copy / pasting the code (from Firefox at least) the line number translate into # symbols which you have to go through and take out.

To copy click the line above the code samples that says ‘Plain Text’ This will convert the highlighted code to plain text without line numbers

Very nicely done. Although I couldn’t open the solution using .NET 2005 as your example code was created with a newer version. But other than that your post stands head and shoulders above the pack. Good work. I look forward to more on NHibernate and perhaps how it integrates with Spring.NET.
Cheers.

Great tutorial. As a newbie to NHibernate and .NET your walkthrough was very helpful and way more straightforward than the other examples I’ve seen.
Thanks again!!

George, this is the beauty of NH, simply change lines 13-16 of the web.config section in the tutorial to:
<add
key=”hibernate.dialect”
value=”NHibernate.Dialect.MsSql2005Dialect”
/>
and you’re done, it’s also more or less as simple to switch to mysql or oracle databases.

Danny,
This was an awesome walk-through, and helped me get through the initial painful steps of learning NHibernate. Any plans on doing the other tutorials you mentioned at the beginning of the post to get into NHibernate in more detail? Again, thanks! This has been a great help!

Hi Danny,
Nice to know you.
This is a great tutorial. I am facing some problems in it. I use a PostgreSQLDialect connection & database connectivity was successful. I have created the required table with the fields. In Postgres i am using a sequence to generate ID. My doubt is where in the project i have to place the HBM mapping file (ie) inside Bin or AppCode, & what should be changed inside the HBM mapping for the “ID” column and my other doubt is i am not able to see the Embedded resource property anywhere in my project so that i can set the build action. rite now i am not able to generate DLL’s on runtime
Please help !!!
