Bean MethodNotFound Exception though it looks correct

[eswar]

hi - this looks obvious but I am not sure if Camel has any restrictions in
using the bean which is defined with parent and as singleton. I m using
Camel 2.12.2 and this works all fine if I use a simple class(without any
superclass) with a method in it.

Also I do have AOP's defined on certain methods inside this bean, but I am
creating a seperate method in the class to use in Camel route.

Below exception is what I get when I use a method from such a bean, any
suggestion would be really helpful. thanks.

Camel Context - 

<camelContext id="camelRoute" xmlns="http://camel.apache.org/schema/spring";>    
        
        <routeContextRef ref="Route1"/>
        <interceptFrom>
        <log message="INTERCEPTOR #######." />
                <bean ref="testBean" method="camel1" />
        </interceptFrom>
</camelContext>

Bean Definition -

<bean id="testBean" class="com.test.project" parent="projectImpl"
scope="singleton">
        <property name="prop1">
                <ref bean="prop1"/>
        </property>
        <property name="prop2">
                <ref bean="prop2"/>
        </property>
</bean> 

Class - 

public class project extends projectImpl implements 
inteface1, interface2, interface3 {

        public synchronized void camel1(Exchange ex) {
                System.out.println("test ... ");
        }
        
}
