Dear forum users,

i have an (for me) unresolvable problem with my application when trying to bring it up and running while porting from VS.NET2003 to VS.NET2005.

With VS.NET2003 everything is working fine - i have to say, i'm new to NHibernate but i got NHibernate up and running within 20 minutes on the old VS.NET2003 (i tried the Quickstart guide on this webpage) and my MSSQL database.

Now, VS.NET2005 arrived and nothing works - it seems there are some problems with the config.

I tried to copy the config from the old VS.NET2003 project, but now i have several different exceptions beeing thrown, when trying to build the sessionFactory. I have checked the PDF-quickstart guide ("NHibernate & IIS - playin with cats"), i have viewed the articles at theserverside.net, i read the tutorials codeproject.com, but i can't find the info to have it working :-(

The config i tried is:


the funny exception i recieve is:


i don't understand why it's searching for an hibernate.cfg.xml file when i've placed all that stuff in the web.config file.

then, there was another problem when i tried to have a tag starting like:


then i recieve:


next, i tried to cut out the "xmlns" tag; after that, i recieved:


another issue is:
in VS.NET2003 i have the option to say buildaction -> "embedded resource" for all the hmb.xml mapping files - this option is unavailable for me in VS.NET2005 - it's not there, really ! I don't know why...

please understand:
everything is working fine with VS.NET2003 - but i'm completely unable to get it up and running on VS.NET2005. As said before, i'm fairly new to NHibernate and database programming - before that i acted in standard application development, tools for games and such stuff... but sorry: i don't understand why this stuff won't work on VS.NET2005.

please help !


*****EDIT******

now, what i tried last was, i copied the _original_ config file from the quickstart guide, which looks like:


and everything what i recieve, is, the above already mentioned:


HELL, please help me !
are the quickstart guide examples VS.NET2003 specific ?
i don't understand why it says: "xmlns unrecognized" if i can see that the build-in XML editor is proposing the tag "xmlns" when i start typing - all that stuff worked *perfectly* with the old VS.NET2003 application....


****EDIT NR.2****
i tried both NHibernate versions:
1.0.2 and the latest alpha.

no difference - i get the same error...


****EDIT NR.3****
for some reason, i get different exceptions when switching the name of the hibernate-config block, from:

to (example):

in the first case, it says ""Unrecognized element."; in the second case it says the above mentioned exception with the looonnnggg text ("unable to parse config...").
SORRY, i don't understand why it throws different exceptions depending on THE NAME i have chosen for the name of the config block ??????

Please post the <configSections> part of your web.config as well.

Right now, it just can't find your config section so it's looking for the cfg.xml file

The usage should be either:



or



I use the second way and then configure like this:

new Configuration().Configure().BuildSessionFactory();

I have another suggestion I just thought of... If this is a web app, then you might want to install the patch for VS2005 to give it Web Application Project support:

http://msdn.microsoft.com/asp.net/refer ... fault.aspx

Then re-upgrade your project from 2003 to 2005. I think you'll be much happier with the transition.

hi benhyrman.

thank you for your reply.

here is the missing part of the web.config file (even if i haven't posted it, doesn't mean i've forgotten it :) )


just right now i'm going to try the update/patches you mentioned; but i'm wondering: why do i have to install some updates to have the same functionality !? surely, i'm not dumb - but i can't understand it ???

you said:

to be honestly: i don't know where is there some difference between the first and the second part of the way to configure.

in my old project, everything looked like the above posted sections.
in the new project i get different errors each time i try somehting.

i can tell you somethign: this shit is now taking more than 3 weeks !

i've found a webproject of vs.net2005 outside there, its from a private blog; this guy just build an additional assembly, with all the stuff inside it - i tried this: when i try it the way like this person did it, i just recive "dialect not set"-exception, although i've included the hibernate.cfg.xml in both, the addon-assembly itself and the mainproject.

really, i swear you: i've done bigger projects like this one, but i can't believe its so frustrating to get nhibernate up and running on VS.NET2005.

If you use the "nhibernate" section, then the config file must contain the <nhibernate> element and its contents should be <add key="hibernate.some_key" value="some_value" />. Note that it's <nhibernate> and that it doesn't contain the <session-factory> element. I suspect that this is your problem.

If this doesn't help, please post all the data about your last attempt - i.e. the entire configuration file here, the code you are using to configure and create the session factory and the exact error message you are getting from NHibernate.

hi sergey,

thank you for the information.

i noticed the missing "n" at the beginning of the tag, yes - this was because i copied these part out of the VS2003 project, where i have it written without the "n" (this was renamed by me in the new web.config for the VS2005 project).

regarding the sesseionfactory passage:

this is the original part of the app.config of VS2003 project; as you can see, i have no session-factory part; and this config is working for the VS2003 project. i don't understand why i need to have a "sessionfactory" part in VS2005 projects, when it works without on VS2003 ?

the problem regarding the config seems to me was as following:
for some reason it seems to me it's a definite must (in VS2005) to place the hibernate configuration in a seperate/extern xml file, when trying to integrate it into the web.config it won't work...

currently i have the following situation with the VS2005 (web)project:
it compiles and runs without exception during initialization.
it seems, everything is fine now - but i still have one problem:
all Session.List()-calls are returing an empty list with no items included, this is because i haven't embedded-resource-compiled the hbm.xml files for the tables - as said above, on VS2005 ASP.NET websites its no more possible to select this build action.
Then, i thought it will be okay if i do a simple cfg.AddClass(...) - but this call returns with an exception, saying it can't find the file XYZ.hbm.xml - i placed this files in two different locations (root of project & bin-folder), but it tells me the error all the time - so, please tell me, where to i have to place the XYZ.hbm.xml files ?

benhyrman,
thank you for the info with this patch. it seems some kind of inconvenient to me to install two patches before using the stuff :-/ so i will do this if i can't find any other solution; but as said above, it looks like i'm reachin the point where it will work.

First, please read carefully what I and others wrote about nhibernate/hibernate-configuration elements and what goes into which one, it looks to me that you are still mixing things up. But I admit it is a confusing area.

You can use Configuration.AddFile or AddDirectory to add mapping files which are not embedded resources.

Hi.

yes, i'm aware of that the block/tag names of the config-passage must match the name in the <configSection>.

Finally, i got it up and running, just 2 minutes ago:

- i built an extra DLL/assembly for the dataaccess, as mentioned in other forumposts.

- then there was the first problem: i called the function AddAssembly(...) on the new DLL/assembly; this is not necessary, and it told me all the time "dialect not set"; then i found out - by trying&erroring - that i don't need to call AddAssembly(...) when i have placed the stuff in an extra assembly - i don't know why and i don't understand it, but it want's it that way

- the next proble was an exception with text like "...get_id needs to be virtual...":
for some reason i need to have the functions in the .cs-class declared virtually (even if use no derivation/inheritance)

- no i've placed the config in an extra xml file; but i will try, putting it back into the web.config (by the way, is there and advance when placing the config in a seperate xml in comparison to the web.config-way ?)

all that stuff is really confusing :-| but luckily it works, now.
