CannotLoadObjectTypeException in Spring.net

I'm using spring.net 1.3.1 in a asp.net 3.5 project in vs 2010. I'm not doing any kind of mvc stuff; I needed Spring to create and manipulate objects.

I've followed the documentation, added Spring.Core and Spring.Web dlls reference my web.config is like this:

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

  </sectionGroup> 
   <system.web>
     <httpModules>
        <add name="Spring" type="Spring.Context.Support.WebSupportModule, Spring.Web"/>
     </httpModules>
     <!-- no spring confi in httpHandlers-->
  </system.web>
   <spring>
    <context>
      <resource uri="~/config/clients.xml" />
    </context>
  </spring>

in clients.xml

<?xml version="1.0" encoding="utf-8" ?>
<objects xmlns="http://www.springframework.net"> 
  <object id="CAL"  type="myrouter.clientcode.CAL, myrouter.clientcode"/>  
</objects>

in Defaults.aspx.cs

  IApplicationContext ctx = ContextRegistry.GetContext();
  CAL calobject = (CAL)ctx.GetObject("CAL");

i'm getting

Sorry for this long post; I wanted to be as precised as possible and give as much as information that I could. I think I'm missing something but just can't figure out what. Is the HttpHandler a must in spring.net configuration in asp.net?

Usually this issue is the result of some error in your

<object id="CAL"  type="myrouter.clientcode.CAL, myrouter.clientcode"/>  

configuration.

Check/verify the following:

• the namespace myrouter.clientcode is really where the CAL class exists
• the assembly that contains this type is really myrouter.clientcode
• these namespaces and assembly names match in re: case-sensitivity as well

Never mind, i got it fixed.i used the wrong assembly info.
