No unique bean of type [javax.persistence.EntityManagerFactory] is defined

I am new to Spring and am trying to go through 2 books and online help to get it set up to access the database but my page keeps giving me the above error. Can someone please help me identify what I have configured incorrectly?

The full error is:
org.springframework.beans.factory.NoSuchBeanDefini tionException: No unique bean of type [javax.persistence.EntityManagerFactory] is defined: expected single bean but found 0

Thank you for your help.

I see, I missed the code tag. Thank you. Here is my post again:

What's the full stack trace?
That error is usually the cause of another one (initialising another object), so there should be a reasonably big stack trace which would tell you what it was trying to create.

Thank you. I was copying an example from a book and mistakenly left in the JPA filter in the web.xml file. Here was the code that I needed to remove:

Code:

---

    <filter>
        <filter-name>Spring OpenEntityManagerInViewFilter</filter-name>
        <filter-class>org.springframework.orm.jpa.support.OpenEntityManagerInViewFilter</filter-class>
    </filter>

Thanks for posting your solution.
