Error creating a proxy-Help!

[vjavle]

I wanted to get started with AOP, so simplified Spring.AopQuickStart.Step1 sample to fit into simple VS.NET 2005 project.
I get following error "Unable to cast object of type 'CompositionAopProxy_6839ee888b5144eb86aa6df347e48 e21' to type 'ICommand'" while creating proxy.

Following is the code and web.config.Any help is appreciated. Thanks

class Program
{
static void Main(string[] args)
{
IApplicationContext ctx = ContextRegistry.GetContext();
//Get error here on line below
ICommand command = (ICommand)(ctx["myServiceCommand"]);

command.Execute();
}
}
interface ICommand
{
bool IsUndoCapable { get; }
void Execute();
void UnExecute();
}
class ServiceCommand : ICommand
{
bool ICommand.IsUndoCapable
{get { return true; }}
void ICommand.Execute() {}
void ICommand.UnExecute() {}
}
config file below:
<?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>
<resource uri="config://spring/objects" />
</context>
<objects xmlns="http://www.springframework.net">
<description>An example that demonstrates simple AOP functionality.</description>
<object id="myServiceCommand" type="Spring.Aop.Framework.ProxyFactoryObject, Spring.Aop">
<property name="Target">
<object type="ServiceCommand, SprintNetAOP" />
</property>
</object>
</objects>
</spring>
</configuration>
Thanks

Hi,

In short: making ICommand public should solve your pb.

Your is most likely caused by the ICommand interface not being public. Due to being internal, the dynamically generated proxy class can't implement the interface.

Yes! Thanks. That was it.
