XML mapping to objects - Model 2 architecture for config file.
This may be a bit inappropriate for this group, but it follows on the heels
of me implementing the Model 2 architecture we all have been discussing so
much. I have a working Model 2, but, I want to read in my xml config file. I
am using the sun/xml parser because we use it in a couple of places on our
site. However, my first stab at reading in the XML into a DOM object, while
its being read in, trying to get each element and its value (not attribute)
has proven to be a pain in the butt.
So, my question is, is there any way I can just create a class and have the
XML parser map the right elements (by name) and place the values after those
tags directly into an instance of an object? It would also need to be able
to add items to a vector, or table of some sort. For example, my config file
looks like so:
Login
com.bm.ui.actions.Login
Enroll
com.bm.ui.actions.Enroll
So, if I have class like:
public class ActionObject
{
private String actionName = "";
private String actionClass = "";
private Hashmap results = new Hashmap();
public ActionObject()
{
}
... and so on ...
}
Is there a way to automatically get the XML document to map the ,
and tags and attributes and their values directly
to an instance of the object..so that I can do something like:
... read XML document in...
ActionObject ao = new ActionObject(XmlDoc);
while( ao.hasMoreActions() )
{
Object o = ao.nextAction();
mytable.add( o );
}
In sum, the few lines above would simply use my ContollerServlet
(ServletContext) hashtable object that stores each action, to cycle through
my own class (ActionObject) which when created was populated automatically
(perhaps through reflection of xml to the object) with the xml config data,
and now I am just looping through and adding it to the hash table.
OFcourse..if ao contains the entire config tree..there is no need to do
another table..this is all hypothetical..for the use to hopefully explain
what I am trying to do.
Thanks for anyone that can help.

I'm putting the finishing touches on a small Model 2 based framework that will be open sourced, and will contain the following tools: * Basic "model 2" servlet with action interfaces and some other support classes. * Custom tag library for some common use cases in Model 2 scenarios, including internationalization. * Support for populating bean properties directly from request parameters (like JSP can do with the "*" wildcard). * Processing XML files like the one above, and creating new objects (and populating properties) from them elegantly, based on simple processing rules that you define. Look for an announcement of code availability for this for JavaOne. In addition, I will be present at many of the BOFs and Sessions (TS) related to servlet and JSP technology, including speaking at some of them. This code will be one of the case study examples. Hope to see you there! Craig McClanahan === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

hi Kevin
Pending the release of the Java XML Binding
implementation you could use DXML from ObjectSpace
http://www.objectspace.com/downloads/

I only get to go for two days, so I want to make sure I make the most of my two days. My main focus/interest will be on servlets, jsp, javabeans, and ejb use with the model/action framework we have been discussing. You should put the framework on CD for the show! ;) Sounds great. The open-source framework you are working on sounds right up my alley. Any idea when it will be done and ready to be used? === To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".

Hi,
you can also take a look at BeanMaker from IBM's alphaworks.

Re: XML mapping to objects - Model 2 architecture for config file.
I have a question...
What is meant in this case by Model 2? Just a set of JSP pages that are
using servlets for their actions? If not what else constitutes model 2? Just
using servlets are "controllers?" ie. directing navigation, fetching data
etc?
