Error loading ApplicationContext

[pcorp]

I have a very simple app context file as follows:

<?xml version="1.0" encoding="utf-8" ?>
<objects>
<object id="userData" type="CDICommon.Model.Security.UserData, CDICommon"/>
</objects>

When I try to load as follows:

IApplicationContext appCtx = new FileSystemXmlApplicationContext(@"C:\CogentWorkspace\CDIClient\bin\Debug\projectPlug in.xml");

I get the following stack trace:

Unhandled Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.ApplicationException: Object definition does not carry a resolved object class
at Spring.Objects.Factory.Support.AbstractObjectDefin ition.get_ObjectClass()

I have verified that the UserData class is in the CDICommon assembly and all the paths are correct. Any idea what is causing this? Any help would be most appreciated. Thanks.

Hi,

The attribute name is class and not type. Yet another implicit vote to change it to use type and not class. :)

Use the following instead

<?xml version="1.0" encoding="utf-8" ?>
<!DOCTYPE objects PUBLIC "-//SPRING//DTD OBJECT//EN" "http://www.springframework.net/dtd/spring-objects.dtd">
<objects>
<object id="userData" class="CDICommon.Model.Security.UserData, CDICommon"/>
</objects>


The DTD declaration will now help in showing a better error message...



0 [456] INFO Spring.Objects.Factory.Support.AbstractObjectDefin itionReader - Loading XML object definitions from URL [C:/temp/projectPlugin.xml]

etc...



FYI, the latest dtd/xsd are available on the web. (They are also in the distribution)

http://www.springframework.net/dtd/spring-objects.dtd
and
http://www.springframework.net/xsd/spring-objects.xsd

Hope this helps you get started!

Cheers,
