JSF Spring integration issue

Hi All,

I am using JSF for the front end and using the Spring Core, DAO and AOP for the BO and DAO layers. When i try to inject the Objects using the DI to the JSF, i am getting the following error and the objects are not getting set from the Spring.

Error Log:
javax.servlet.ServletException: Unable to create managed bean dataUploadControllerBean. The following problems were found:
- Bean or property class #{dataUploadVO} for managed bean dataUploadControllerBean cannot be found.
- Bean or property class #{dataUploadVO} for managed bean dataUploadControllerBean cannot be found.
- Bean or property class #{dataUploadVO} for managed bean dataUploadControllerBean cannot be found.
javax.faces.webapp.FacesServlet.service(FacesServl et.java:325)
org.apache.myfaces.component.html.util.ExtensionsF ilter.doFilter(ExtensionsFilter.java:112)

i have defined the respective entries correctly to integrate the JSF & Spring. But still the JSF&Spreing is not integrated successfully. Please find the configs defined and help to resolve the issue. i am stuck in this for 2 days...
