Horizon: a view management plugin
Hi,
I have built a plugin for Struts that creates view beans using
dynabeans that are defined on a xml file and i was wondering if anyone
in the Struts project/mailing list was interested on checking the use
of it?
It is a very simple plugin (i call it Horizon... because it can have a
lot of views :) )
but it gave me a big help on some projects i am currently working on...
who knows somebody may find it useful :)
I will be waiting for a response for those who maybe interested
(i will send a war file with a sample application, source code and javadoc
documentation).

i think, actually, there is none... the difference is for what i use
the view beans for: transfering data from actions to
build combobox on form and present data that isn't on a form.
i know i can use the form itself to put a collection to
build a combobox and use another form bean property
to store the user input but it is less
confusing if i define forms with only the properties the
user can enter data and
another bean for transmitting data (dto... in my case i call it view bean).
before the plugin i had to define a new java class
(attributes + getters/setters) for each
new dto i wanted, now, i only need to add some lines
to a xml file...

I have already sent the source on another email so
you can take a look (src + javadoc + ant file)
and i am finishing a small web app.
thanks for the tips...

The beans are defined on a xml file.
<views>
<view name="myView">
<dyna-property property="attributeName" type="javaClass"/>
</view>
</views
> Can you specify validation with the beans?
no... what do you mean by validation with the beans?
i use my views like a DTO and i copy the dao/bo values
(never thought of doing validation on this step...)
to it with BeanUtils or PropertyUtils.

i use it as a Struts plugin but you can use the factory in anyway you
want...
In attachment goes the source code.
Put in the lib directory:
commons-beanutils
commons-collections
commons-digester
log4j
servlet.jar
struts.jar
later i can email you an web app example... so you can take a peek
at a real cenario.
it doesn't do nothing yet but if you run ant javadoc you could check
the javadoc documentation docs/api...
the license is missing but it will be open (don't know
what open source/free software license to use).
Comments and ideas for improvement are welcome :)
Hope you find it has useful as i did,

Tell me more about your plugin.
How are the beans defined?
Can you specify validation with the beans?
How dependent is this project on being loaded within a servlet container
or more specifically, a Struts plugin? (e.g. Can I use it in a
standalone app?)

When I see dynabean are you saying BeanUtils.DynaBean and what is a
'view bean',
do you mean a Action Form ? If so what is the difference between your
plugin and a DynaActionForm ?
Given that your plugin is generally useful then there are several options :
1) Since web space can gotten for free now days you could always post it
on a site with
some documentation on how to use it.
2) We are using the http://www.sf.net/projects/struts site as an
incubator for projects you can post there
to see if there is interest.
3) Find someone else with a struts web site, that would host it.
Most importantly having an example, that is documented is key.

Pedro,
I'ld be interested in your implementation as I did the same thing.
I define what I call view configurations in an XML file. On startup
they are cached and I can access them at run time. It sure beats
writing a bunch of throw-away Java beans which are used to present
data.
Accessing a particular view configuration is as simple as:
DynaBean view = ViewFactory.getInstance().getView(viewName);
