Alternatives to this hack ?

2002-11-09 Thread Paul Campbell 

First, I just used the JSTL taglibs-mailer for the first time. 
It was remarkable how easy and effective it was.

My hack was that I wanted to execute to method
in a bean ef and then to do a getProperty to obtain
the result of the method.

I executed % ef.doToString(); %
and then 
 jsp:getProperty name=ef property=done /

doToString normalizes and concatenates a string into 
a member done.

From my readings of JavaSererPages(Bergsten) the EL
does not provide a technique to execute a method 
such at % ef.doToString(); % which I could use
in the EL based mailer or assign to a variable.

Is there a better way of executing a method that returns
a sting into an EL variable?

Or is that to be fixed in the next release?

Just a quick correction.  The Mailer Taglib is not part of JSTL.  It's an
offering from Jakarta Taglibs, which is not identical with JSTL.

The Mailer Taglib doesn't support the JSTL EL, and the EL in JSTL 1.0
won't let you access that method unless you provide a wrapper class.  In
JSP 2.0, you'll be able to associate that method with a function.
