Hi,
I am trying to iterate the object stored in session using struts nested tag.
I am getting an exception javax.servlet.jsp.JspException: Cannot find bean:
"" in any scope. What am I missing in the following code. I do not want to
have the Action class and action form bean. I have a need to access the
session object and display the results. Here is my code and appreciate if
some one helps me out.
Regards,
Smitha
