Error instantiating context - beginner

[hpa]

High,

I use spring Ioc for the first time in a service layer.
I have succesfully tested this assembly with a new project (console). Now I try to access my service layer from a web project. I've pasted the sections from my first app.config (console) to the web.config, and I get the folowing error :

Error instantiating context
at System.Web.Configuration.HttpConfigurationRecord.E valuate(String configKey, SectionRecord section)
at System.Web.Configuration.HttpConfigurationRecord.G etConfig(String configKey, Boolean cacheResult)
at System.Web.Configuration.HttpConfigurationRecord.G etConfig(String configKey, Boolean cacheResult)
at System.Web.HttpContext.GetConfig(String name)

at Spring.Context.Support.ContextRegistry.CreateConte xtIfNeeded()
at Spring.Context.Support.ContextRegistry.GetContext( )
at SuiviPiges.Services.UtilisateurService.GetUsersADN onUtilisateurs()"

Here is the web.config :

<?xml version="1.0" encoding="utf-8" ?>
<configuration>

<configSections>
<sectionGroup name="spring">
<section name="context" type="Spring.Context.Support.ContextHandler, Spring.Core" />
<section name="objects" type="Spring.Context.Support.DefaultSectionHandler, Spring.Core" />
</sectionGroup>
</configSections>

<spring>
<context caseSensitive="false" type="Spring.Context.Support.XmlApplicationContext, Spring.Core">
<resource uri="config://spring/objects"/>
</context>

<objects xmlns="http://www.springframework.net" >

<object id="Session" type="SuiviPiges.FmkImpl.Session, SuiviPiges.FmkImpl">
</object>
....

What's wrong ?
Thnaks in advance,

Try to use the WebApplicationContext :

http://www.springframework.net/doc/reference/html/web.html#web-configuration

Thanks for this answer.
I've modified the web.config :
<configSections>
<sectionGroup name="spring">
<section name="context" type="Spring.Context.Support.ContextHandler, Spring.Core"/>
<section name="objects" type="Spring.Context.Support.DefaultSectionHandler, Spring.Core" />
</sectionGroup>
</configSections>

<spring>
<context type="Spring.Context.Support.WebApplicationContext, Spring.Web">
<resource uri="config://spring/objects"/>
</context>
<objects xmlns="http://www.springframework.net" >

<object id="Session" type="SuiviPiges.FmkImpl.Session, SuiviPiges.FmkImpl">
</object>
...
</objects>
</spring>

<system.web>
<httpHandlers>
<add verb="*" path="*.aspx" type="Spring.Web.Support.PageHandlerFactory, Spring.Web"/>
</httpHandlers>


<compilation defaultLanguage="vb" debug="true" />
...


... and I've got a new exception now :

Thanks in advance for your help.

Do u referenced the 'SuiviPiges.FmkImpl.dll' in your new Web Project ?
The dll should be in the bin directory of your Web Application.

Thank You for this advice, it was a beginner's mistake...
I haven't referenced the dll (I want the web layer to be independant of the implementation) but I have copied the dll in the bin directory, and everything is OK, now.

Thank You again, and have a nice day !
