Maverick

File Release Notes and Changelog

Release Name: 2.1

Notes:

The Maverick MVC Framework

Version 2.1

2.1 refactors the Maverick architecture to accomodate
heterogeneous transforms, a consistent framework for
passing params to views and transforms, and a more elegant
way of setting the model.

The maverick config file format has changed slightly from
2.0.  Transforms are now specified like this:

    <view name="foo" path="blah.jsp">
        <transform type="xsl" path="makefo.xsl"/>
        <transform type="fop" output="pdf"/>
    </view>

The multiple-path-for-single-transform-node syntax is no longer
allowed.

In addition, <param name="foo" value="bar"/> child elements are
allowed on controller, view, and transform nodes.


This release of Maverick requires:
	JDK 1.2+
	JAXP 1.1
	Servlet API 2.3
	A whole slew of jars which have been included in the dist.
	See the FAQ or the examples for a list of what is necessary.

In particular note that Maverick requires a web container which
supports the Servlet 2.3 API.  It is possible to get it working
with a 2.2 container, but with a much restricted feature set.

Maverick 2.1 is known to work with Tomcat 4, Jetty 4, and Orion.
If anyone is using Maverick with another application server, drop a
line on the mav-user mailing list (mav-user@lists.sourceforge.net).
Maverick should work with any web container that supports the
Servlet 2.3 specification.

Note that Orion 1.5.4 has a broken ServletResponseWrapper which
is incompatible with Maverick (or the Serlvet specification).
According to bugzilla, this will be fixed in Orion 1.5.5.  If it
is ever released :-(

Thanks,
Jeff Schnitzer

Version 2.1     6/11/2002

- Heterogeneous transforms are now supported.
- A Context object is now passed to Controllers, Views,
  and Transforms rather than a multitude of arguments.
- The model is now set on the context explicitly rather
  than being returned from Controller.go()
- Params are supported on controller, view, and transform
  nodes.  Params are interpreted differently (but hopefully
  in an intuitive and consistent manner) by each pluggable
  module.
