The difference bewtween
<jsp:useBean
<jsp:setProperty
</jsp:useBean
and
</jsp:useBean ... />
</jsp:setProperty />
is that in the first case the setProperty only gets called when the bean is
created, whereas in the second case the setProperty is always called. I
prefer the first case for a number of reasons -
I can't accidently do this
<jsp:useBean />
<% use the bean %>
<jsp:setProperty />
It gives me better 'encapsulation', I'm sure the bean is fully constructed
before using it, etc.
You pays your money and you takes your choice.
