greetings & a newbie question

[dasa]

hi,

just joined the list, and i have a newbie question about struts design.

this is where i am at. i have looked at struts about a year back, and rolled
my own version of mvc web architecture, stealing several basic ideas from
struts.  at the time, it appeared that many features of struts were not
apparently applicable to the project, so the overhead of configuring struts
didn't seem justifiable.  now the need for many of the struts features has
become pretty concrete, and so i am in process of incorporating struts
rather than re-inventing the wheels (and axels and cupholders, etc).

while adapting the code base to use struts, i get the sense that:
these are the classes/packages; for many, you can configure/adapt it to your
needs via config files; in other aspects, you may want/need to subclass and
override some of the classes to fit your needs.

for the later category of adaptation (subclassing/overriding), the best way
seems to be to look into the source to ascertain the default behavior and to
ensure the overriding implementation is proper.

to put it simply, struts' interface doesn't seem to be clearly defined.  by
"clearly defined" interface, i mean programming/usage could/should be
via/against the interface without delving into implementation details.  if
not, pointer(s) to the authoritative interface defnitions would be much
appreciated (i told you i'm a newbie).  but if so, is this deliberate?  and
the reasoning behind?  some obvious (generic) arguments i could see are:

1. it's advantageous in order to provide greater flexibility, struts being a
development framework
2. struts (and web app requirements) are progressing rapidly, so loose
interface may serve the purpose better

are there more specific reasons other than these?  or perhaps it is simply a
documentation issue?

thanx for any insight/info,

dasa

ps: i am sending this to both the user and dev lists, thinking the subject
is of interest to both.  perhaps you'll correct me.  again, a newbie here.

Hi all,

  Other possibility is to check whether 'myBean' exists in some scope. 

Cheers,

objects.

RE: ActionForm boolean properties - Newbie question

If its a primitive , it will look for 'is' , but for the Boolean object it
will look for 'get' (same as any other object).

I have some trouble using a boolean (the primitive type) property inside
an ActionForm. What I'd like to know is if Struts looks for a
getProperty method or isProperty method... It seems Struts always calls
the getProperty, but as I know it should call the isProperty!!
Is the behavior with a Boolean (Object type) property the same ?

First, your class name should begin with a capital letter by convention. The
error is saying that no constructor an be found that matches "myABC

How about your struts.jar?  You might have multiple copies of it, and the

That excactly what I'm doing. At the login, the business logic checks
if the credentials supplied were right. If so, the user object will be
stored in the session. In that way, I can easily access all the user's
properties without doing a lookup all the time. You might run into
memory problems if you have a lot of simultanous logged in users
and/or big user objects. But that not the case for me. Additionally,
I'm storing a list of the users group membership in the session. So I
can do fast permission checks based on this list (always doing a
lookup for every groups is expensive).


JH> I mean using bean:write tags of the "User" object seems straightforward

I don't really understand. I'm using code like this to access the
user object:


  <%-- check if the users object is stored in the session--%>
  
<%-- it's not, present a "you're not logged in" message --%>

  

  <%-- the user is logged in --%>
  
<%-- present a welcome message like "Welcome, John Doe." --%>
, ${sessionScope.user.name}.

<%-- display the logout form --%>

  
  <%-- the requested page parameter is used to return to this page 
after logout --%>
  
  

  


As you can see, I read and display the user's name with
${sessionScope.user.name}.

But I have to warn you, I'm a struts newbie too.. :)

Utter Newbie Question

[Joe Hertz]

I'm making using struts for more or less than first time.

I read the FAQ on how to handle logins to an application and I'm left with 
one question:

Why stop a storing a Boolean in the session to determine "logged-inness"? 

Why not just store the (validated) "User" object in the session and check for 
it's presence? That way, if it's there, one can utilize the data in the User 
object for whatever sordid little purpose said developer comes up with.

Is this a good idea?

If so, how do I go about doing this in the view? (I told you I was a newbie!).

I mean using bean:write tags of the "User" object seems straightforward 
enough, but what about the List of "Children" objects that is part of 
the "User" object?

TIA

How can I call this sendRedirect() - sounds like the solution to my problem!

contextRelative is used to define a forward that is relative to the 
application context and not to the module context
(default).

You cannot redirect to an URL outside your app using struts-config 
. Use a requestDispatcher in your action and
call sendRedirect(), or create a new JSP with a http://www.yahoo.com";> tag

I'm using a property file names "languages.properties" instead of
"ApplicationResources.properties"
Also I have an entry in my "struts-config.xml" like the following...



I also placed the property file in "WEB-INF/classes/"
but it seems that the property file "languages.properties" is not detected.

shld I make any changes or any entry in the "web.xml" to make my new
property file visible 

I'm using web-logic6.1.

pls help..

Regards,
Mahin

Struts newbie question

[Nathan Maves]

I have a form that has two select boxes.  One need to be pre-populated 
on load.  The second will be populated when a use selects one of the 
elements in the first list.

Can this be accomplished and if so how?

I would really like to use DynaActionForms if possible.

Hi,

Though I am also a newbie, when I faced a similar

RE: newbie question: results display on same page?

[mobile q]

thankyou for your reply.

I did put results bean into request. The problem is:
it
even does not display search form now if I put results
display block after  since user has not
pressed "get" button. Here is my display code:


  
   ..
  
 

I only use bean:write tag to output individual table
data.

I also tried to put the above code inside html:form
tag,
and use logic:present to chech if results bean is
present. I still could not display search form and got
"null":





According to api, if resultsBean is not present, it
should check non-null results, and let search form
dislay, right? 

dun know why it did not work..

RE: newbie question: results display on same page?

[Nicholson, Robb]

The logic:iterate tag does not have to live within a form. Chances are your
error is because the Collection you are trying to iterate over is not in the
request (or whatever session you happen to be using).

What we normally do for a situation like this is to create a JSP with the
search form, and another with the results iterator. Then use TILES to pull
them together on one page. It's flexible enough so you can reuse one or more
component elsewhere, or change your mind and separate them later, etc.

Hi,


I am working on a page which has a user search form,
the results should be displayed at the bottom of the
page once user clicks on "get" button. 

I try to use logic:iterate tag to do the job. My
problem:
if I include this display loop inside html:form, it
tells me the results are null when I navigate to this
page since user has not pushed "get" button. If I put
results dipslay code right after , it
tells me "Cannot find bean

logic:iterate tag is not used inside html:form tag.

I do not know how to resolve this conflict. Should I
use multiple forms to do this? Not really sure. Really

RE: html tag newbie question

Hi, 
I still don't know how to do it. 
I try to avoid hard code anything, have any logic, have html tag, and have
javascripts in jsp file.
Overall, jsp file will just display whatever I got from properties or beans.

Is there a way to do like this for example: ">images

RE: newbie question: how to handle two dispatchAction methods in a jsp page?

[Jerome Devost]

If you need to change the action of the form, you can do this in the onclick
event : 

document.formName.action = "/delete.do"  

If you change the action, you probably won't need the method parameter then.

Be sure that you do not have an element in your form called 'action',
otherwise it will confuse Internet Explorer.

I have two jsp pages. sicpage0.jsp and sicpage1.jsp

sicpage0 is a static page. when I submit sicpage0, it calls an action
class which populates sicpage1.jsp with data.

Now I want to call sicpage1.jsp directly without first calling
sicpage0.jsp.

But sicpage1.jsp is not getting populated with data since the action

Newbie question, dynamic select boxes

[Jose Maria Fernandez]

Hi you all, i'm starting with struts and after reading and testing a bit, i
have a  question.

Suppose I create a form where the user should choose a car model, for
example, lets say model1, model2 and model3. Suppose that i need to get that
models of a database. And suppose too that after the user choose the model i
want to store that reference in my database. Which is the best way to
implement such things? Where should i retrieve the values from the database?
maybe in the form bean?

Really, i think my question is: what to do when I need to show in a form
dynamic data coming directly from the storage medium?

Sorry if the question it's quite obvious but i'm a bit lost :)

RE: newbie-question: validation across multiple pages

[Yansheng Lin]

You might want to use session to store all the values entered in page=1.
Then when there is an error in page=2 or page=3, and forward the control 
back to page=1.  Since all the values are session scope, you can access them
in your page=1.  Remember you have to clean the session though:).

if(! errors.isEmpty()) {
...
return (new ActionForward("page1"));
}

the third page is empty after submit, the framework will take me back to
the first page. How can I make him turn me back to the page where the
input field was left blank?

Greetings
Sebastian

RE: Newbie question about form name

Your action is configured with a form name.

Lookup action element in your struts-config.xml, 
Attribute of interest there is 'name' is the name of the form.
When you specify action in your html:form Struts connects the 
dots for you.

That form will be used to populate values of  -Original Message-

Newbie question about form name

[MaFai]

Hello, struts-user,

Sth make me confused while reading the type.jsp,one of examples in Tomcat Strut 
struts-validator.war.

The following is the souce code.

  

My question:
why the form doesn't need the form name and form type.

For my limited skill,I would write this code:


Do the form name has default name? But I think the type should hardcode in the jsp 
page.

In strut-config.xml



   


The form type (TypeForm object) doesn't contain the form type,but the action form type 
is specified.




Best regards.

Hi,
There are no exceptions at all! Once the
FormBean is executed the control is not passed on to the Servlet!

If so, show a snippet.

Hello,

This question probably might have been asked many a times. But I searched
the archive (though not fully) but could not find this. So, if anybody has a
solution please do let me know.

I have developed a sample application, which takes in an input and based on
that displays either a success page or failure page. The problem am facing
is the servlet is not being called. Below is the sturts.config.xml, b.xml
and index.jsp. Am using jdk1.4.0 and tomcat 4.1.12.

The java class files are under WEB-INF\classes\myapp package.

Re: newbie question: Java array to JavaScript Array

[Kris Schneider]

So it's still not working? Can you post some of the generated 
JavaScript? I was shooting for something like this:

var products = new Array();
var productBeans0 = new Array();
productBeans0[0] = ["name0", "id0"];
productBeans0[1] = ["name1", "id1"];
...
products[0] = productBeans0;
var productBeans1 = new Array();
productBeans1[0] = ["name0", "id0"];
productBeans1[1] = ["name1", "id1"];
...
products[1] = productBeans1;
...

Man, this is really sick ;-). If I'm understanding

Quoting Rick Col <[EMAIL PROTECTED]>:


Hi,

I did the following, but the results were not
displayed.
Whats wrong with my code?
products is a collection of ArrayLists, every
arrayList contains
a list of ProductBeans, ProductBean has
productName

and productId properties.

products are retrieved in action class and are put
into session scope:
session.setAttribute("products", products);
var productsArray = new Array();

indexId

= "idx">
	
indexId = "index">
		productsArray[<%=idx%>][<%=index%>] 
			= new Array(
property = "productName"/>,
			   
property = "productId"/>);
	


Thanks in advance.

More questions about the following:

1) It says in logic tags reference:
id: "The name of a page scope JSP bean that will
contain the current element of the collection on
each
iteration, if it is not null."
So, it means myList ArrayList should conform
to JavaBean routines, is that right? For
example:

If I have a List4Js class, it has to have
getters/seters
for getting/setting ArrayLists:
ArrayList myList = List4J.getResultList();

And the elements of an ArrayList should be a
bean

too.

2) If I want to get a collection of arraylists,
I

can
use the  tag as following:
name="listForJavaScript"

indexId="idx">
   
indexId="index">
   jsArray[<%=idx%>][<%=index%>] = 
<%=myBean.getYourValue()%>;
   	
		

Since JavaScript Array usually has the following
form:
 myArray = new Array("sample", 1);
Do I need to conform to the above routine to
create

an

JavaScript Array element in order to correctly
display
the results?

rick
