jstl - define bean
I thought <c:set ...> defines a new bean in page scope. If this is true
I do not understand why attached code keeps throwing exception that no
getB() is not defined.
<c:set property="b" value="kicha" var="d"></c:set>
<html:link forward="gtLogin" paramId="ddd" paramName="d"
paramProperty="b">Login</html:link>

Grzegorz-
Yes - Unless otherwise specified you are correct in stating the default
scope for the bean is 'page'

This is equivalent to <% d.setB("kicha"); %>

You're telling the html:link tag to create a parameter named 'ddd' whose
value is taken from the property B of bean d. In other words, you're
telling it to add a parameter whose value is d.getB(). If d's type
doesn't define the accessor properly, Struts won't be able to call it.
