Injecting property into a abstract class

[Yared]

I have the following two classes. The one is abstract base class and the other extends the abstract class.

public abstract class AbstractSimpleFormController extends SimpleFormController{

private String selfRedirectErrorView;

public final void SetSelfRedirectErrorView(String selfRedirectErrorView){
this.selfRedirectErrorView = selfRedirectErrorView;
}

...

}

public class SignUpFormController extends AbstractSimpleFormController {

...

}

My Application context is configured as follows:

<bean id="signupFormController" class="com.web.SignUpFormController">

...
<property name="selfRedirectErrorView"><value>redirect:/signup.htm</value></property>

</bean>

Now when I try to start the application, I get the following error. Can someone help me? I thought I can inject into the property of a base class. What is going wrong? I also tried by making the base class non-abstract but got the same effect. I also changed the private property of the base class to protected with the same effect. I'm using the Spring version of 1.2.6.

public final void SetSelfRedirectErrorView(String selfRedirectErrorView)

It needs to be setSelfRedirectErrorView (note the lower case 's'). All the methods that are being injected into need to conform to the JavaBean specification.

This is also why its a very good idea to follow the Sun coding conventions - http://java.sun.com/docs/codeconv/

Oh, what a silly mistake! Thanks Cow Boy!
