Re: html taglibs

[David Goodenough <da...@btconnect.com>]

Either I have completely misunderstood your problem or this already exists 
providing you are using the right level of JSP.  I do not know what container
you are using, but with Tomcat, 4.x and before did not allow this, 5.x does.

You also rarely need <c:out> these days, you just put the EL expression in
the text.  It can also be put in attributes.  The only time you have to be
careful is in writing your own tags.  I had some tags which I had written
the support code myself, and in the old setup I had to say that EL was 
allowed for its parameters and then call upon EL handler functions to 
translate the expressions.  I had to take all that code out for the new
Tomcat as the expressions have already been resolved.
