Well, there's lots of ways to do it... html:link is one of them... 
expresso:TransitionTag is another easy way to create buttons.  Another way is:

<bean:define id="url" property="yourTransition.url"/>
<bean:define id="label" property="yourTransition.label"/>

Then you can do your html anchor with the appropriate labels, etc.

Using the results above, you get the same results unless I'm 
misunderstanding the question.

TransitionTag will do all that automatically for you.  Take a look at it 
and let us know if it helps.
