All, make sure you check out the new release of Mach-II 1.5 Beta and the new
website at www.mach-ii.com. Here are a few of the new features:
- *XML includes**
*The Mach-II application is built around a common XML configuration
file in which you can define events, filters, plugins, listeners and other
components and specify how they work together to manage the flow of your
application. In larger Mach-II applications, it is common for config files
grow to several thousand lines, making them more difficult to maintain.
With Mach-II 1.5, you can now break apart pieces of your main XML file
into smaller XML documents and include them from the main configuration file
using the new <include> tag.
- *Modules (sub / peer applications)**
*Mach-II 1.5 ushers in a powerful new feature with the addition of
Modules. Modules are stand-alone reusable sub-applications that you can
plug into parent Mach-II applications, which then share the application
scope of the parent. For example, if you have a common login application
that you use throughout your application development, you can add that as a
Module to an existing Mach-II application. With this feature, developers
can easily create and share Modules for other developers to add to their own
applications.
- *Subroutines*
Subroutines can be though of as a resusable block of configuration XML
that you can define and then execute at various points in your Mach-II
configuration file. If you have a series of listeners that are announced
in multiple events, you may wish to create that series as a subroutine and
include them where you need to with the new <execute/> tag in the
configuration file.
- *<redirect/> command enhancements
*Until the release of Mach-II 1.5, the <redirect/> command has offered
a way to perform a clientside redirect to a new URL by performing a
<cflocation/> call under the covers. Due to the redirect being a clientside
request, one challenge that has existed was the inability to copy complex
arguments to the new event. With the new <redirect/> tag, you can add the
attribute *persist="true"* which copies the current event arguments to
the target event.
Additionally you can now define the status type of your redirect. By
default, ColdFusion's <cflocation/> command does a 302 redirect ("moved
temporary"). With the new redirect functionality you can specify the status
type that you wish to return to the browser. For example you can set the
*statusType* attribute to "Permanent", "Temporary" and "PRG" for
post-redirect-get.
- *Complex property datatypes*
The release of Mach-II 1.5 also brings with it the ability to define
complex data types as properties in your Mach-II configuration file. Until
this release this was often managed through use of Plugins that existed only
to set these properties. With 1.5, you can now define Properties in
your XML of types Array, Structure, and even ColdFusion Components (CFCs)
with the use of the new Property.cfc.
- *URL management features**
*New to Mach-II with the 1.5 release is the ability to bind and manage
URL formatting within the framework. With the new BuildUrl() and
BuildUrlToModule() functions in the framework, the developer has the ability
to format URLs in countless ways. This means no more having to use custom
code outside the framework to apply SES URLs to your application.
*
*
- *Bindable placeholder support**
*Another feature that is part of the Mach-II 1.5 release is the
ability to have bindable placeholders. While Mach-II has long afforded the
ability to define parameters to Plugins, Listeners, and Filters, the value
had to be hardcoded in the XML which offered limited benefits. With
1.5, you can now define bindable parameters that can be assigned at
runtime. For example a DSN parameter could be set like this: <parameter
name="Dsn" value="${MyDsn}" /> where "MyDsn" is a Mach-II property.
- *Other enhancements
*Numerous other enhancements have also been added such as a more
detailed Trace Plugin, optional "reinit" attribute for event-beans,
enhancements to how defaultEvents and exceptionEvents are handled. Major
performance enhancements have also been added in the initial loading of
Mach-II applications, and several small bugs have been addressed.
