Re: Mixing Velocity and JSP
If Velocity had a syntax for passing a block of the template to an object in
the context for transforming, it could have support for BodyTags as well
(these are by far most interesting; Struts, OpenSymphony OSCache or SiteMesh
come to mind).
Folks, I swear my only intention mentioning what follows is to help the
original poster find the tool that suits his needs best. I'll mention this
only once and won't descend into lengthy discussions or comparisons. No
flame wars, please. I even sent this message (modulo this sentence) to Geir
for review before posting it here and waited until he gave the green light.
The current CVS HEAD of FreeMarker has its own lightweight JSP runtime
support I wrote around two months ago that can host any JSP taglib when
run in Servlet environment. It is slated for 2.2 release, for which we have
scheduled the first public preview in a next week or two.
A sample of using Struts inside a FM template looks like this:
<#global html=JspTaglibs["/WEB-INF/struts-html.tld"]>
<#global bean=JspTaglibs["/WEB-INF/struts-bean.tld"]>
<html>
<body>
<h1><$bean.message key="welcome.title"/></h1>
<$html.errors/>
<$html.form action="/query">
Keyword: <$html.text property="keyword"/><br>
Exclude: <$html.text property="exclude"/><br>
<$html.submit value="Send"/>
</$html.form>
</body>
</html>
This is equivalent to the following JSP page:
<%@page contentType="text/html;charset=ISO-8859-2" language="java"%>
<%@taglib uri="/WEB-INF/struts-html.tld" prefix="html"%>
<%@taglib uri="/WEB-INF/struts-bean.tld" prefix="bean"%>
<html>
<body>
<h1><bean:message key="welcome.title"/></h1>
<html:errors/>
<html:form action="/query">
Keyword: <html:text property="keyword"/><br>
Exclude: <html:text property="exclude"/><br>
<html:submit value="Send"/>
</html:form>
</body>
</html>
As I said, Velocity could have similar support as well if it had a notion
of context objects that can process a block of template body and a block
directive that passes its block to such context object.
Attila.

What do you mean? Say, if the "command" is index.do, and I create a
real file (does not mater what does that contain), then
<welcome-file-list>
<welcome-file>index.do</welcome-file>
</welcome-file-list>
will suddenly work.

Actually since my web app was small enough I just converted
everything to use Velocity instead of JSP. My JSP tag library was
simple enough that I just did it all using a Velocity template and
moving some code into the appropriate command class.
The problem with this is that I know lose my welcome pages, as far as
I can tell when I convert all my JSPs to Velocity. I need to figure
out if there is a way to specify a command to be called instead of a
welcome page. I almost get the impression Turbine would solve this
problem for me but I do not know enough about it.
