Hey Scott,

In practice, the Struts Distribution works like any other Servlet bases
Web-App... Download struts and deploy the examples to tomcat (you do not
necessarily require Apache, since struts is Servlet based technology)... in
other words you really only need a Servlet Container... 

Good Luck

Subject: Installation Getting Started Question

 
I am wanting to see how Struts may help in my J2EE development. I have
purchased the O'Reilly book "Jakarta Struts" and want to get started with
some examples.
 
1) I am currently running Tomcat 4.1.31 as a standalone.
Can struts be installed with Tomcat as standalone? I saw somewhere in
the install where it says to make sure you have Apache and Tomcat installed?
Can someone help clear this up?
 
2) Is there a hello Struts example somewhere? Just to test the install/setup
before I get under way?
 
 
3) The book does not start off simple either, so how can one get a handle on
this effectively? My background is Servlets/JSP/ Web development. Including
taglibs, ant, etc. 
 
 
Thanks,
Scott

Subject: Hate Myself for Not Getting Drop-Down Menu Right

There is no problem with the database operation.  Data
are retrieved and can be displayed using the
 tag.  Now, it is the drop-down menu.

I have coded some drop-down menu before.  This time, I
have a collection of JavaBeans instead of a collection
of strings.  And, I am in trouble again.

I passed a collection of JavaBean(s) upon successful
completion of an action:

Collection pages = service.getPages();
request.setAttribute( "PageBeans", pages );

The individual JavaBean in the Collection is called
PageBean.  The PageBean has only one property called
'name' (I made it simple for testing purpose) with the
get and set methods.  

In the listpages.jsp, I imported:

<%@ page import="org.dhsinfo.content.PageBean" %>

<%@ taglib uri="/tags/struts-html" prefix="html" %>
<%@ taglib uri="/tags/struts-bean" prefix="bean" %>

To form a drop-down menu, I did:







I got this error:
Http Status 500 root cause 

javax.servlet.jsp.JspException: Cannot find bean under
name org.apache.struts.taglib.html.BEAN

and in the Tomcat logs file:

2004-09-20 12:03:38 ApplicationDispatcher[/DHSInfo]
Servlet.service() for servlet jsp threw exception
javax.servlet.jsp.JspException: Cannot find bean under
name org.apache.struts.taglib.html.BEAN

Updating select list...

2004-09-09 Thread Amin Lalji 

Hey All,

I have a slightly complex problem:

I have a dynaform which creates a set of input boxes (address information
etc.) to be filled in based upon a number the user specifies at runtime:

E.G 

Choose how many addresses you would like to add?

(assume user chooses 3)

Three sets of input boxes (indexed) are created listing
Name, Address, Phone, etc...

Each set of boxes includes a dynamically populated select list.
At runtime, the select list may need to be updated with additional entries

How can I add extra entries to the select list, and refresh the list, all
without losing the information the user may have already entered?


Thanks

RE: Theoretical debate

2004-06-17 Thread Amin Lalji 
I recently downloaded IBATIS in order to use it for some object
persistence... interestingly, their JPetStore implementation used a similar 
idea, although it was all struts based:

Essentially, each "method" you want to call is actually mapped within the 
Action Mapping... so if you wanted to "searchProduct", then your mapping
could be:


  


Where the CatalogBean has the required method (searchProducts)

It seems pretty neat so far... haven't had much time to play though...

Subject: Theoretical debate

Last night I was Googling for something and I stumbled across the Crysalis 
framework.  I was actualyl intrigued by the underlying premise of it and I 
wanted to see what others thought about it.

In a nutshell and in my own words, Crysalis 
(http://chrysalis.sourceforge.net/) has the underlying idea that when you 
develop in most MVC frameworks, Struts chief among them, you are actually 
doing something unnatural and in a way at odds with basic OOP design.

Think about a shopping cart example... If you were going to write that in 
straight Java, not for the web or anything, how would you model it?  Most 
likely you would have a ShoppingCart class with a number of methods in it, 
things like addItem(), removeItem(), totalPrice(), etc.

In Struts, although you aren't FORCED to, what you GENERALLY do is create 
three different Action classes like addItemAction, removeItemAction and 
totalPriceAction, and each is called in response to a form submission.

But isn't it kind of odd that your object model isn't following what you 
probably think in your head is the right way, i.e., one class with multiple 
related methods?  Proper encapsulation and all that jazz, right?

Well, Crysalis does just that.  It's controller elements are regular Java 
classes with multiple methods.  What you wind up with is something that 
resembles Remote Procedure Calls instead of numerous servlets as 
controllers.

In other words, you would create the ShoppingCart object just as I described

above, with all three methods.  Then, when you submit a form, the action is 
something along the lines of "ShoppingCart.addItem.cmd".  ShoppingCart is 
the class to execute, addItem the method and cmd is a suffix to direct the 
request, just like extensions in your Struts apps map requests to 
ActionServlet.

The elements of the submitted form are treated as the parameters of the 
method being called, making it rather elegant.

I haven't gotten into any real detail on Crysalis, but I was interested in 
getting other peoples' thoughts on the underlying principal (which I *THINK*

I've stated properly!).  It was rather interesting to me because I'd never 
reall considered looking at it that way, and certainly it's not the way you 
typically approach a Struts-based application.  It was also interesting to 
me because I've for about four years now been preaching here at work that we

should write our applications as a collection of services that are executed 
to form a coherent larger application, which is very much along the lines of

this (so I guess I actually HAVE looked at it this way in a sense, but not 
exactly).

Any thoughts?

Frank

Indexed Properties DynaValidatorForm

2004-04-19 Thread Amin Lalji 
I am trying to use a DynaValidatorForm with Indexed Properties...
I have setup validation using the Validator Framework...

Validation is working, however when it comes time to display failed
validation (from ActionErrors), I can not seem to output an individual error
message for each indexed property... instead validation errors for a single
member of the indexed properties are displayed for all of the members ... 

Is there any way to display the error solely for the Indexed Property in
question?

Thanks,

Amin

Im not sure how to do it with the iterate tag, I use the c:forEach tag in

the jstl taglib.

 

It goes something like this:

Assume service is a bean with accessors getDocuments ( ) and getId ( )

Assume document is a bean wit accessors getId ( ) and getName ( )

Here is the Data structure:

 

I have two tables (Services, Documents)

I hit the database and pull two separate Collections.

I need to iterate over both collections... here is the relationship:

 

ServiceID

ServiceName

Documents

  DocumentID

  DocumentName

 

So a service object contains a collection of documents

 

I need to be able to output something like:

 

DocumentName

 

---

Contract

 

Deposit

 

Contract

 

Deposit

 

In my action, I created a DynaActionForm.

I set a java.util.ArrayList property called requiredDocuments in

struts-config.xml

 

In my action I make the database calls, then I iterate the services

collection creating a RequiredDocumentsBean (contains serviceID,

serviceName, and documents Collection)

 

I populate the first two properties (serviceID, and serviceName) and then

iterate the documents collection setting a LabelValueBean

 

Here is the code:

<-- snip -->

while(sIterator.hasNext()){ // for each service...

RequiredDocumentsBean rd = new RequiredDocumentsBean();

ServiceBeanLocal service = (ServiceBeanLocal)sIterator.next();

  rd.setServiceId(service.getId());

rd.setServiceName(service.getServiceName());

  Iterator dIterator = documents.iterator();

while(dIterator.hasNext()){ // for each available document

DocumentBeanValue document =

DocumentBeanValue)dIterator.next();

rd.getRequiredDocuments().add(new

LabelValueBean(document.getDocumentName(),document.getId()));

}

requiredDocuments.add(rd);

}

myForm.set("allRequiredDocuments",requiredDocuments);

request.setAttribute("allRequiredDocuments",requiredDocuments);

 

<-- snip -->

 

Thanks

It isn't clear what you have to work with.  Is services a map of some sort,

or is it a collection.

 

Either way you should use the iterate tag in the logic tag set.

 

If you could explain the data structure better, it would be easier to help.
