Hi,

i am getting an error that says

 Invalid property 'onlineAssignmentDao' of bean class [csns.spring.controller.CreateAssignmentController]: No property 'onlineAssignmentDao' found

In CreateAssignmentController.java I have this:

    private OnlineAssignmentDao onlineAssignmentDao;

It has a getter and a setter.

And in spring-servlet.xml within the bean for this class I have:

        <property name="onlineAssignmentDao" ref="onlineAssignmentDao" />

And I have the onlineAssignmentDao bean declared as well.

How come it can't find the property?  The error sounds like it can't find it somewhere within CreateAssignmentController.java, but it is there...

Thanks.

I have checked the spellings, and now I added a UserDao property to test it and that property was not found either.  Would it be correct to assume that it is having problems finding the CreateAssignmentController class?  or would that be a different error?

I assume that was the problem as well. While the above advice did not work, I ended up just moving on and writing another bean.  In the process, I refreshed the project a bunch of times and at some point it stopped giving me that error and ran.  Thanks for your help.
