RE: getting ArrayList elements as objects

[Domen, Ken]

I was hoping by reflection that my sub-object would be re-created
automatically.  This was not the case.
I had to take all the attributes and recreate the sub-object in the
ActionClass and then attach it to the
parent class.

So the jsp code stays "clean" and struts-like

***







***

But in the UpdateMaterialAction class, there's a bit of work:

***
//2.  Grab request params from Bean.  Use this same bean to
repopulate
MaterialBean myForm = (MaterialBean)form;

//3.  Create the Material Object along w/ child Substances Objects
and
// then call business logic in EJB 
try
{
BusinessFacadeHome bhome = this.getBusinessFacadeHome();
BusinessFacade facade = bhome.create();

//1.  This is the parent object w/ parent attributes
Material m = new Material();
m.setMaterialID(myForm.getMaterialID());
m.setSupplierMaterialName(myForm.getSupplierMaterialName());
m.setNikeMaterialName(myForm.getNikeMaterialName());
m.setSupplierProductID(myForm.getSupplierProductID());
m.setNikeProductID(myForm.getNikeProductID());
m.setMaterialDescription(myForm.getMaterialDescription());
 
m.setFinalProductApplication(myForm.getFinalProductApplication());
m.setRemarks(myForm.getRemarks());
m.setMaterialStatus(myForm.getMaterialStatus());
m.setLastUserUpdate(myForm.getLastUserUpdate());
m.setConfirmingUser(myForm.getConfirmingUser());
if (myForm.getExceedsSubstanceLimit()) {
m.setExceedsSubstanceLimit("1"); }
else { m.setExceedsSubstanceLimit("0"); }

//2.  Struts does not automatically re-create sub-objects for
you from the jsp-- this doesn't work
ArrayList list = myForm.getSubstances();
System.out.println("list.size(): " + list.size());
Iterator i = list.iterator();
while (i.hasNext())
{
Substance s = (Substance)i.next();
System.out.println("s.getCasNumber(): " + s.getCasNumber());
}

//3.  So we have to reconstruct the sub-object and attach it to
the parent node-- this works.
String[] substanceNames =
request.getParameterValues("substanceName");
String[] casNumbers = request.getParameterValues("casNumber");

Subject: getting ArrayList elements as objects


I want to be able to get (after a submit) the values of the iterator
as an ArrayList of objects in the action class.  Currently, substances is
an ArrayList in bean Material.  

How do people achieve this?  Or is there a work around?

RE: getting a list in Action class

[Domen, Ken]

Here's my problem:

During a display of the page, I use:








But I also want to update the values.   
The html then becomes:





















So now, the bean doesn't find any getSubstanaces(ArrayList), it only sees a
bunch
of casNumbers and substanceNames.  If I say, getCasNumber() in the bean, it
only
gets the first one.

How do people deal with this in struts?

tricky!
does
   myForm.getSubstances();
return a list? is it the correct size?
I would have thought putting enough debug messages would highlight the
problem.
I'd guess it's not even executing your debug code because you'd get a null
pointer exception from list.iterator() if the list was missing &
CalssCastExp
if you got the wrong list. 
Intriguing! (Most likely something really obvious... bit I can't see it.)

yes that's true, try to check whether the web.xml file is well formed or not
as well as check if the web.xml is valid(i mean check against the DTD
mentioned on top of the web.xml file).

I ran into the same problem once, first time it was uri issue next time I
had the DTD part on top of web.xml wrong. 
hope that helps

if the web.xml file has the following taglib declaration

how to decide how many beans to use?

[Domen, Ken]

I'm running into a problem.  

I started out with one FormBean.  It's basically a flattened domain object.
I'm using the Dave W. Validation package and in the validation.xml, you
define
that for a particular FormBean you validate certain fields.  Different pages
need validation on different fields so using only 1 FormBean won't work.

So do you create a new FormBean for each page that needs different
validations?

thanks.

Most of the time, the app runs fine but once in awhile, it will cause it a

Any ideas?

Do you have a corresponding ActionForm containing these methods:
