Summary: Add ability to render results of a JSTL SQL Tag's query
Initial Comment:
It'd be nice if the displaytag could render the results
of a JSTL SQL Tag Query. For example:
<sql:query var="users" dataSource="jdbc/appfuse">
select username, firstName, lastName
from app_user order by upper(username);
</sql:query>
I patched the main library to add this feature - but
wanted to check w/ all developers before committing it.
Most changes are to the ExpressionEvaluator in the EL
package. I also added a new "items" attribute to be
consistent with JSTL's forEach tag, and renamed the URI
in the el.tld to be http://displaytag.sf.net/el. The
URI in the 2 tld's much be different or user's won't be
able to choose (using just a URI, no web.xml def). The
diff on the TLD is not very accurate - it shows I
changed the whole file, but I really only changed a few
lines (URI and new items attribute).
I also had to alter the list and tableIterator
variables to be protected. Another option is to add
setters for them (however, setList is already deprecated).
You can see an example of this new library at
http://demo.raibledesigns.com/appfuse/users.jsp.
Please let me know what you think - and I'll commit it
if everyone likes it.
