problem with struts bean:define tag

843838Oct 4 2005 — edited Oct 4 2005

I was configuring the Jpetstore sample.
I was using Myeclipse to debug the jsp page
when the step goes to
"
<bean:define id="category" name="catalogBean" property="category" />
"
I got the following exception "define tag connot set a null value"
"javax.servlet.ServletException: Define tag cannot set a null value
org.apache.jasper.runtime.PageContextImpl.doHandlePageException(PageContextImpl.java:848)
.........
"

what's the possible causes of this exception.
I'm a newbie of J2EE, any help or advice will be great appreciation
