Re: [Springframework-developer] am I missing something

Hi Keith, we have developed a tag to put a bean in one scope of the 
view. I have attached it, and I hope it will be what you need.

Usage example:

  ApplicationContext:

   <bean id="myBean" class="...">
     ...
   </bean>


  JSP View:

  <%@ taglib prefix="dco" uri="http://www.disid.com/tags/dco" %>

  <dco:defineBean name="myBean" var="mb" />
  <c:out value="${mb.property}" />
