As the Struts documentation will tell you, multiple controller servlets is
not a supported configuration.  It's going to cause you nothing but grief,
because the code in ActionServlet assumes that it is a singleton.

Problem With Multiple ActionServlet - Urgent

2003-01-27 Thread ashokd

Hi,

I defined two ActionServlets, first one is the default ActionServlet and second one is 
Custom ActionServlet.

The purpose of Custom ActionServlet is to redirect login page when the user name is 
not in session.

For loginpage action we need to call the default ActionServlet. 

Default ActionServlet is mapped to *.do

Custom ActionServlet is mapped to *.go

Problem:

In login page action we given 



but it is coming 



I think this text will be replaced by struts frame work in login page.

Where we need to configure to get




web.xml:


  
action
org.apache.struts.action.ActionServlet  

  application
  ApplicationResources


  config
  /WEB-INF/struts-config.xml


  debug
  2


  detail
  2


  validate
  true

2
  

  
newaction
com.vstl.wspr.WSPRActionServlet   

  application

  /WEB-INF/struts-config.xml


  debug

RE: Filters and Struts

2003-01-27 Thread Sterin, Ilya

Ok, thanks to all:-)  Guess my only other option is to either define a
filter for each servlet for now, until 2.4 is prod ready, or as Max
mentioned, and put all actions in need of authentication, within the
members namespace. 
 
Both are a hassle of course as compared to a simple filter:-), but
that's what we'll have to live with for now:-) 
 
Any idea of when the 2.4 spec and tomcat will be production ready? 
 
Thanks.

I did some more checking on the 2.3 Spec and you are correct that it
does not allow for specific include requests.  I believe Craig had
mentioned before in Tomcat-User that the Filter chain is created once a
request, which would not accommodate dynamic includes.
 
Servlet 2.4 Specs
http://jcp.org/aboutJava/communityprocess/first/jsr154/
 
 
With 2.4, you can define lots more in your filter-mapping for includes,
specific GET/POST requests etc.  I'm finishing up a robust caching
framework with the use of tags/filters, and the 2.4 features will really
simplify filter functionality, even with Security Filters.

Hmmm, I'm successfuly using it with 2.3 just filtering jsp pages in a

I can of course filter each individual servlet, but that undermines the
whole filter cause, IMO, that way I can just use a authentication
function in each servlet.

I use JSP to render XML with the standard Struts tag libraries and it
works quite well.  The  tag already supports DynaBeans,
 works great for looping through data structures, and so
on.

A trivial example similar to the XML document listed in the page you
referenced (assuming a collection of "books" that is either JavaBeans or
DynaBeans):

  <%@ page contentType="text/xml" %>
  <%@ taglib prefix="bean" uri="http://jakarta.apache.org/struts/bean"; %>
  <%@ taglib prefix="logic" uri="http://jakarta.apache.org/struts/logic"; %>
  

  



  

  

Of course, you can do the same thing with JSTL tags if you've got standard
JavaBeans as the backing data.

Form Design Problem

2003-01-27 Thread K Viswanathan


Hi ,

I have a requirement where user has to fill up some kind of questionaire
form. Questions for a user depends on the "type" of a user. In essense we
have a form containing questions which could be different based on the user
type.  Questions are basically mutiple choice questions and the user can
select the correct answer by selecting a radio button .

Now I want to use struts validation frame work for performing validations.
If the user leaves any of the answers empty by not selecting the radio
button , the system should not accept it and report an error displaying the
same form with all the data entered for the form.

The question is how can i use the validation framework to perform
validation? Please note that the form fields change so it is not possible
for me to associate them in "validator.xml"  before hand.

Any inputs would be appreciated.
Thanks
Vishy

Having a controller doesn't avoid the need to synchronize things that get
modified -- consider a shopping cart implemented as an ArrayList
maintained in the session, and a JSP page that uses  to
display it.  If the List is modified during the JSP's iteration, the page
is going to throw a very ugly ConcurrentModificationException.

By the way, here's two trivially simple ways to cause this problem:

(1) Use frames where the pages in each frame reference the same
collection, and at least one of the frames modifies it.

(2) Have users that submit a request, press STOP, and submit another
request.  (You're just as likely to end up trying to do simultaneous
modifications in this scenario, which is even worse than a modification
plus iteration scenario.)

To say nothing of application scenarios where you've cached data in the
session that is being modified by some sort of background process, which
is not unusal in sophisticated applications.

Frankly, I wouldn't obsess about session scoped objects either.  In
order for a thread issue to intrude, they'd have to have two requests
running against the same session at the same time, which can happen
(submit, back, submit), but is uncommon.

Re: JSP cannot call an action in its own module

I thought not accessing JSPs directly was irritating at first too until I

advantages to not do it that way.  What if you don't want to use JSPs in the 
future?  How do you setup the data for the JSP to display?  What if you want

An FYI for all those who have written in with this problem. It seems that 
the available documentation isn't clear enough with regards to JSPs in 
multi-module applications. The Struts developers have confirmed that all 
JSPs must be called from actions and not directly in order for the 
ModuleConfig information to be present. I'll admit this is rather crude and 
annoying, but that's the way it is.

It was decided about 2 weeks ago that the struts 1.1 release would only

Does anyone out there use Scaffold?

2003-01-27 Thread Steve_Akins



We are currently developing Struts apps and incorporating Scaffold code
into them.

Firstly, I was wondering if anyone else out there is using Scaffold code
and what comments they have on their success or otherwise with it?

Secondly, with the latest release of Struts (1.1b3), Scaffold code has been
packaged into the contrib section.  However the commons-scaffold components
are not there.  They are in jakarta-commons-sandbox but only the source in
the CVS repository.  Should commons-scaffold be somewhere in
jakarta-commons now that scaffolds is being packaged with Struts 1.1b3 and
should there be a built version of this code somewhere?

Re: Struts productivity metrics?

I agree with Joe
One such metric is a pro can do a few CRUD modules per day and a newbie
takes a few days per module.

Also... it sounds self serving but. consider hiring a mentor,
someone who put Struts in production before, it is cost effective. They
can kick start you and reduce risk. Some experienced people on this list.

Joe Barefoot wrote:

4) Assuming that struts provides a consistent framework that
is easier to
maintain, is there perhaps a increase in initial development
effort which is
offset by a decrease in the ongoing maintenance effort for
the application?
Can that be quantified by testing metrics like # of issues
reported/module
and avg. # hours required to resolve an issue?

Can't help chiming in here: You're not likely to find any metrics like these, and if you do, you should only use them the way most statistics are--to blindside people into agreeing with your premises. If you think about it briefly, you'll realize that metrics like these will never be that accurate, and even if the metrics themselves were precise, they could never accurately represent quantitative differences between development methodologies or frameworks. The reason is simple: No company ever builds the same thing twice and every project is very different. This makes quantitative apples-to-apples comparisons of frameworks/practices practically impossible in the business world. Perhaps an academic experiment with two teams implementing the exact same spec. with different frameworks would yield some useful information, but any quantitative comparisons you receive from the business world are spurious at best.

You're much better off relying on first-hand qualitative comparisons, e.g. "We were using X for web development and now that we've switched to Struts, I don't have to don my fire hat on a daily basis to douse that conflagaration we called a web app."

Anecdotal comments are appreciated, but I'm mostly interested in hard
metrics (X hrs w/ struts vs. Y hrs w/ 'the old way') if
possible. Also - if
there are any books/sites which address these questions,
please send them my
way.

Re: Filters and Struts

2003-01-27 Thread Max Cooper

Filters do not apply to forwards (I thought that, too, but tested it last
week and they don't). The Servlet 2.4 spec has an option to allow you to
turn such "forward filtering" on.

In reference to the original question, how about naming your action mappings
(in struts-config.xml) so that they can be secured by a url-pattern. For
instance:

members-only: (url-pattern = "/members/*")
/members/editUserProfile.do
/members/viewSecretMembersOnlyStuff.do

public:
/index.do
/public/viewPublicStuff.do
/anything/else/isOkayForPublic.do


Generally, I think developers spent way too much time writing their own
security systems. Having worked on such implementations myself, I must say
it can be surprisingly tricky to make the system secure, flexible, and easy
to use. I think the first step should always be to learn the
container-managed system and use that unless you have a *really* good reason
not to. Often, a combination of container-based and programmatic security is
the best approach.

For some projects, my filter-based clone of container-managed security is a
good solution:

If you're modifying them, you definitely should -- there are lots of cases
where it is possible to have multiple simultaneous requests for the same
session.

Note that it is *not* the session.getAttribute(), session.setAttribute(),
or session.removeAttribute() call that needs to be synchronized -- the
container takes care of that for you.

Re: JSP cannot call an action in its own module

2003-01-27 Thread Milo Hyson

An FYI for all those who have written in with this problem. It seems 
that the available documentation isn't clear enough with regards to JSPs 
in multi-module applications. The Struts developers have confirmed that 
all JSPs must be called from actions and not directly in order for the 
ModuleConfig information to be present. I'll admit this is rather crude 
and annoying, but that's the way it is.

New release of sslext available (1.1b3)

2003-01-27 Thread Ditlinger, Steve



I have posted a new version of sslext (the Struts extension for HTTP/HTTPS
protocol switching) for Struts 1.1 beta3 at sslext.source.net.

I have also posted new releases of the Struts 1.0, 1.1b1, and 1.1b2
versions.  These releases fix a bug with the sslext.tld that never showed up
until I tested with the 4.1.18 version of Tomcat.  (Enforcement getting
stricter, I like that!)  

The 1.1b3 version includes a new feature that was recently requested: the
ability to disable the HTTP/HTTPS switching.  This is something you may want
to do temporarily if your SSL is non-functional for whatever reason.  This
is done using the new "enable" attribute for the SecurePlugin specified in
the struts config file.  If not specified, the default value for this
attribute is "true".  


The 1.1b1 and 1.1b2 versions do not include this new feature and will
probably not be updated from this point forward except for bug fixes.

Stand by for other new features.

Frankly, I wouldn't obsess about session scoped objects either.  In
order for a thread issue to intrude, they'd have to have two requests
running against the same session at the same time, which can happen
(submit, back, submit), but is uncommon.

Hi, 

For my project I will use Struts and WebService and I'm asking what's the
best to do for dealing with DB connection ?

Thanks in advance.

Re: TilesPlugin : factory already exists/no hot deploy

2003-01-27 Thread Nicholas Grabowski

Looks like the change in the implementations made no difference. 
Although, the TilesPlugin : factory already exists. No new creation
message is gone.

Please review code for LookupDisptach using Image Buttons

Hi,
I have a jsp with 2 image buttons, and i needed to
forward the request to different jsp depending upon
the image button clicked by the user, and I want to do
it without using javascript ( I was using javascript
along with DispatchAction class)
Here is what I have done,
I wrote a new class called TestLookupDispatchAction
which extend DispatchAction class, override execute
method and has one abrstact method called
getMethodName
I am pasting the code of my 
TestLookupDispatchAction and the class which extends
this TestLookupDispatchAction class and my jsp
definitation of code,
Can people please comment on it
public abstract class TestLookupDispatchAction extends
DispatchAction
{
 public ActionForward execute (
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception
{
String methodName = getMethodName(request ,
mapping);
  return dispatchMethod (mapping, form,
request, response, methodName);



}

protected abstract String getMethodName
(HttpServletRequest request, ActionMapping mapping );
}

/** class that extends this class**/

public class TestImageButton extends
TestLookupDispatchAction
{
protected String
getMethodName(javax.servlet.http.HttpServletRequest
request, ActionMapping mapping)
{
Enumeration enu = request.getParameterNames
();
String att="";
while(enu.hasMoreElements ())
{
att = (String)enu.nextElement ();
System.out.println ("parameter name: " +
att + "... value: " + request.getParameter (att));
if(att.equals ("add.x"))
{  
  return "add";
}
else if(att.equals ("change.x"))
{  
 return "change";
}
else if(att.equals ("back.x"))
{  
 return "back";
}


}
return "";
}

 public ActionForward add (ActionMapping mapping, 
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException
{

}
}

[html:errors] Displaying error with form elements

2003-01-27 Thread Ashish Bansal

Hi!
I am a new bie with Struts trying to figure out a way to display form
errors along with the form elemtn which was the source of the error.
For example, if the form is for new user registration, and it had two
errors - a. User name already exists 
 b. passwords dont match
these would be shown next to the respective form elements where these
were entered.
I am trying to accomplish this usng Struts. This is what I understand
how this could be done:
  For each form tag
analyze the errors collection {
 if error key matches some value (using the logic:) {
   render tag differently
   display the message
 }
}
I am wondering if this is the most efficient way of achieving this? 
Also, can we extend Struts error display such that for every html form
tag, it takes a property displayErrors=true or something to that tune,
which causes the error message to be displayed along with the tag as
the tag is being rendered. Is this extension already planned for
development/exists? Would be interested on working on that because I
think that would a very useful feature.

Looking forward to your thoughts!

Rendering of large and/or complex HTML tables in IE and Netscape can be 
pretty CPU-intensive for a short time. We noticed a short CPU spike 
every time that page was loaded - I at first assumed it was the 
action/business-logic/JSP-population that was responsible, but the 
minute we changed the output to send XML to Flash instead of HTML to 
browser, the spike totally disappeared.
It probably doesn't hurt that JDOM is lightning quick for outputting 
documents to a stream (small ones, at least) - I don't know how fast or 
slow the code is that Jasper generates from JSP (but I do know that it 
is ugly ;-).

Re: TilesPlugin : factory already exists/no hot deploy

2003-01-27 Thread Nicholas Grabowski

David

Yeah, Unhappily I am being forced to use weblogic and due to the
deployment of mutiple EJBs, etc. at start time it takes me several
minutes to restart the server.

I noticed that there is a change in the implementation in struts 1.1b3
from struts 1.1b2 on the exact line where the null pointer exception is
being thrown.  I.E:
String prefix = appConfig.getPrefix();
becomes
String prefix = moduleConfig.getPrefix();

I haven't really investigated, but I wonder if this solves the problem
or acts a little more gracefully (rather than throwing a null pointer
exception). Any thoughts?

I wouldn't be surprised if the nested tag actually does support the property but it 
was accidentally left out of the .tld and is thus giving you grief.  On the other

2003-01-27 Thread Jeff_Mychasiw


Thank for the reply.

I should have tried a bit more before mailing but the panic of construction
deadlines..

You are right about the filter attribute being present.

I should have been clearer that I was using nested Tags, and that is where
the problem is.
I converted this:  ( the exception states -  Attribute filter invalid
according to the specified TLD)




To this:




So I guess the fix is an easy but sure like using nested tags,
We are actually using a hightly between b2 and b3. perhaps it is already fixed.

Until that time I guess thats what JSP comments are for..

Thanks again..

h...subclass the OptionsTag and add the filter attribute to your class?
I peeked at the 1.0 code and it does a ResponseUtils.filter on whatever you
give as the label, with no filter option.  The nightly build javadocs have
a filter attribute on OptionsTag...are you sure that the 1.1b2 OptionsTag
doesn't have a filter property that is either undocumented or accidentally
left out of the tag descriptor?

RE: Dynamic populating HTML form

Yes, it can, by using a Collection or array of objects and using indexed property 
notation in the JSP (e.g. myDynamicList[0].name, myDynamicList[0].id, 
myDynamicList[1].name, myDynamicList[1].id).  

Search the archives (http://www.mail-archive.com/struts-user%40jakarta.apache.org/) 
and/or the web for indexed properties and dynamic collection population.  Should be

[OT] Synchronizing Session Objects

I haven't found a definitive answer to whether you should synchronize access 
to objects stored in the session scope.  Do you have to put a synchronized 
block around session objects when iterating over them or modifying them?  
I'm guessing that if you treat session or application scoped objects as read 
only you don't have to synchronize.

Thanks,
David

Subject: session creation time
Date: Mon, 27 Jan 2003 17:29:32 -0500

when you try to obtain the session creation time, it is returned in Long
format, which doesn't let you use the  tag easily.

In theory, what I am trying to accomplish is Date dt = new
Date(session.getCreationTime());

however, i was wondering if there was a way to accomplish it completely 
with
taglibs instead of having scriptlets.

The code below returns the Long value of time.

Date: 27 Jan 2003 14:20:49 -0800

I am trying to "hot deploy" struts action classes, forms, etc. on a
running weblogic server 6.1 (compile the classes and use them without
restarting the server).  However, quite often (although not always) I
get the following error.  It seems that if I've already used the action
in question, and then change the code, recompile it, and test the same
scenario (a request for a page that causes an action to be used) then
the server throws this error.  Is what I'm trying to do even possible
with struts/tiles?  Or does it require a restart before it can use
changed class files?  Could this be a classloader issue?  THat would be
first guess since I doubt Tiles or struts decides when and if to rreload
a class?  But if this is the case, why is struts throwing the null
pointer exception?

Thanks

Dynamic populating HTML form

2003-01-27 Thread Joyce Gu

Hello, everyone.
I have the following questions, I do not know if strut can handle them?
1) My first jsp page will input a field "number of users", after submitting, 
the action will call the second page, which will populate corresponding fields 
which has unique number of user id, name, address, and etc fields. For 
example, if the user input 4 in the first JSP page, after he/she submitted, 
the next page will have to populate 4 field, which has user id, which gets 
from database generated from sequence number, and meanwhile, it has to 
populate 4 of "name" field, 4 of "address" field, all in text input field, 
which will be entered by user. If the user enter "11", it has to populate 11 
of individual field.

2) After the user click submit button, it will populate several dynamic html 
pages under one action, whenever the forms are associated with "number of 
users", it has to be able to dynamiclly populate the corresponding HTML field. 
I do not know if sturt can handle this. 
I am using strut-1.0.2, and tomcat4.1.12.

Any suggestion is greatly appreciated!

Thanks

RE: Two ActionForms colliding on property name

2003-01-27 Thread Derek Richardson

I have gone back and read the posts on action chaining to October 21 2002. If I need 
to go back further, let me know. I have rethought why I am chaining the actions and 
this is what I have come up with.

As I understand it, this is the popular and well-liked Struts convention:

Action1 -> JSP1 -> Action2 -> JSP2 -> Action3 -> JSP3 -> ... -> ActionN -> JSPn

This seems somewhat messy to me because a single Action has to handle both 
post-processing the last JSP and pre-processing the next JSP. For instance, Action2 
has to both do whatever it has been asked to do by JSP1 and also prepare for the 
display of JSP2. So, (1) Action2 will first take some input from JSP1 and save it to 
the model and then (2) read some other data from the model and package it up for JSP2 
to consume. This strikes me as two logically separate concerns being coupled together 
in a single non-cohesive action.

The model that is more intuitive to me is:

PreAction1 -> JSP1 -> PostAction1 -> PreAction2 -> JSP2 -> PostAction2 -> ... -> 
PreActionN -> JSPn

Of course, in some cases the post-processing of the last request *is* closely linked 
to the preprocessing of the next response. In this situation, the current convention 
works well. However, imagine the case of coming out of the last JSP in an "Add Foo" 
wizard. You want to (1) save the new Foo and (2) redisplay the list of all Foos so the 
user can decide what to do next. These two activities are not closely linked. 
Additionally, consider that you also can come out of a "Delete Foo" page where you 
want to (1) delete the outdated Foo and (2) redisplay the list of all Foos so the user 
can decide what to do next. Not only are the activities not closely linked, but it 
sure would be nice to have an Action that encapsulates the common activity #2 so that 
code doesn't have to be duplicated. Notice, in this case, there is no pollution of the 
Action by business logic: all the action does is call a method on the business logic 
facade to get a Collection of Foos and then put it in the request scope. I don't see 
any non-cumbersome way of eliminating this duplication without action chaining of the 
restricted type I am talking about.

In short, some of my Actions prepare data for a JSP to display. I can't forward to the 
JSP without preparing the data first. I may want to forward to the same JSP from 
several different places in my workflow. I don't want to duplicate the data 
preparation code in several different places in my workflow. Is there a solution for 
me other than action chaining?

FYI, I am halfway through the Cavaness book and don't remember seeing action chaining 
discussed. I have not read any other of the Struts books. If what I am asking is 
covered in depth somewhere else, a short summary and a clear citation that will let me 
find the resource is appreciated.

Thanks,

Derek Richardson

TilesPlugin : factory already exists/no hot deploy

I'd be curious as to what you're doing in HTML that could possibly consume more CPU 
than rendering anything in Flash.  I would assume you must have some massive JS 
arrays/functions to cause appreciable CPU consumption of the sort you describe.

Re: Flash+Struts how?

I wish I could add something more, other than repeat what has been said:

http://www.mail-archive.com/struts-dev@jakarta.apache.org/msg12987.html

It seems that Flash/SOAP/Beans is mostly Model/View, however it is very 
marketable.

I like cybersage.com as well, and avoiding Remoting Server (license cost 
in case of MS). There is also an open source someplace looking for 
the link.

Nice attitude. I hope I misunderstood that reply...

Anyway, to answer the original inquiry:
A part of the UI of our app is a flash movie, and we chose to
integrate 
it using XML. The Flash sends requests to our struts actions (they
look 
like any other URL to Flash), but these particular actions return XML

instead of HTML. The Flash parses the XML and applies it to the UI 
appropriately. Works quite well and with no noticeable CPU usage on
the 
client - a problem we had with the previous, complicated HTML
interface 
for this part of the app.
There is also a relatively new feature of Flash MX that provides 
integration between Flash and J2EE apps without using XML in between.

Although I haven't looked at it in detail, I bet it can be used with 
Struts as well as "ordinary" servlets. See

The effort required is not worth fixing the "problem".  The message

Perhaps an Adapter could be created to do this (e.g.

to be your default LocaleContext in the web.xml or via a Struts PlugIn.  I
haven't actually looked to see if a Struts MessageResources could be

Such an Adapter could live in the Struts 1.1 contrib along with Struts-EL.

Re: Two ActionForms colliding on property name

Yet another reason to not use Action chaining.  Maybe you could rethink why 
you're chaining the actions.

Subject: Two ActionForms colliding on property name
Date: Mon, 27 Jan 2003 15:43:05 -0500

I have one action forwarding to another action. The first action and the 
second action both have form-beans specified using the name attribute and 
these form beans are different. Unfortunately, these two ActionForms each 
have an attribute named "value", but in ActionForm one it is a String, 
while, in ActionForm two, it is a List.

You probably already see the problem. Here is what I think it is. When a 
JSP submits to the first action, there is a request parameter called 
"value" which is a String. When the first action forwards to the second, 
ActionForm two is populated from the request, the string is found in place 
of the list, and I get BeanUtil.populate() errors.

Any suggestions (other than changing the attribute names, which is a 
possibility, but not my preference)?

Thanks,

Derek Richardson

It is *possible* that Struts 1.0.2 might work in this environment, but
don't count on any support -- 3.2.1 is absolutely ancient, and has at
least some security fixes that were done in 3.2.4 (as well as lots and
lots of other bugfixes).

Tomcat 3.2 has class loader bugs that prevent Struts 1.1b3 and later from
working at all; upgrade to Tomcat 3.3.x or 4.1.x if you want that to work.

The only thing Struts itself puts in the session is a Locale object for

For servlet 2.3, filters only apply on the original request.  For servlet

a filter to apply on forwards and/or includes.

The whole point of commons-logging was to allow people who want to use
Log4J to be able to use it, and for people who *don't* want to use Log4J
to be able to use something else, without any changes to Struts itself.

My advice is to learn how to configure Log4J in the usual way, and just
let commons-logging use it.

You will see concrete evidence of Struts-JSF integration when the next JSF
early access release becomes available, "real soon now."

However, you should remember what "early access" means -- the APIs of
JavaServer Faces are still changing, and it is way to early to count on
them all being stable.  It will be useful, though, to start exploring how
the technologies can work together.

Even if that does not bother you, note in particular a license restriction
on the JSF EA release (actually on any EA release from the JCP) -- if it's
not final, it's for evaluation only, and you can't ship a production
product based on it anyway.

Short answer - no.

Reason - that would introduce a dependency on JSTL, which in turn would
introduce a dependency on JSP 1.2 and Servlet 2.3, which would be a
problem for more than a few users who are using JSP 1.1 / Servlet 2.2
containers.  We cannot introduce dependencies like this without updating
the baseline version dependency as well.

Java Pet Store rewritten with Flash Remoting Front End

2003-01-27 Thread Haseltine, Celeste

For all those who are considering Flash remoting as another GUI alternative
to HTML, here is the URL to the Java pet store that Macromedia reworked with
a Flash remoting front end.  You can download the code and run it on your
local machine also, if you are interested.  The second link is for FAQ

http://www.macromedia.com/desdev/mx/blueprint/

http://www.macromedia.com/desdev/mx/blueprint/articles/faq.html#pm_accessibl
e

We been using Macromedia JRUN server as our application server for the past
two years, and have used some of the macromedia products in our shop, along
with Eclipse 2.02, for our JSP, Servlet, EJB development.  I did look at
using Flash remoting for our current project when it came out a year ago,
but decided to give it some time in the market place before actually using
it.  My main concern with Flash remoting at that time was how long it would
take for someone on a modem (vs a T1 or cable modem) to navigate and use our
web site. If anyone does actually use it in their apps instead of HTML, I
would be interested in knowing how it worked out for both you and your
customers.

One last note.  It is rumored in the DFW, TX area that Microsoft is
considering a hostile takeover of Macromedia, and that if this does happen,
that Flash remoting would be "bundled" with .NET, and would not continue to
support J2EE applications.  Since we use JRUN as our application server,
I've been keeping my ear to the ground regarding these rumors, as JRUN is
another one of the Macromedia suite of products that MS would probably kill,
if a hostile takeover was successful.  That is something that probably
should be taken into consideration if you choose to utilize this technology
in any new application.  I don't know about any of the rest of you, but I
have been burned by using proprietary code in previous apps, and been left
holding the bag and no source code,  when the company went bankrupt.  I now
utilize and advocate open source code whenever possible.

Nice attitude. I hope I misunderstood that reply...

Anyway, to answer the original inquiry:
A part of the UI of our app is a flash movie, and we chose to integrate 
it using XML. The Flash sends requests to our struts actions (they look 
like any other URL to Flash), but these particular actions return XML 
instead of HTML. The Flash parses the XML and applies it to the UI 
appropriately. Works quite well and with no noticeable CPU usage on the 
client - a problem we had with the previous, complicated HTML interface 
for this part of the app.
There is also a relatively new feature of Flash MX that provides 
integration between Flash and J2EE apps without using XML in between. 
Although I haven't looked at it in detail, I bet it can be used with 
Struts as well as "ordinary" servlets. See

Re: Flash+Struts how?

2003-01-27 Thread Michael C. Clark

Being able to return XML to the UI is not all that bad, when you
consider the opportunities for integrating other technolgies for
presentation (if you like XSLT and the like).

There are also some nice tools that take advantage of the modular
nature of FlashMX, and the native XML parsing capabilities of Flash,
available from Flash5 forward.

For UI components check out www.cybersage.com and Flash developer CD
($99 additional) ... XML opens the door to a *slick* rich client UI.

"I love Struts and I vote"

In the right hands, Flash aint all that bad (but then I don't use
emacs to code JavaBean accessors, so...).

RE: Need input about user authentication with user self registration strategies

2003-01-27 Thread John Cavacas

I realize that this is more of an architecture question and probably should
be labeled [OT]. However, I was looking for more of a Struts based opinion
to these issues.

It seems like I will have to roll my own solution for this. As such, I was
thinking of using the Jakarta taglib session. Does Struts have a tag which
would provide me with similar functionality? I might just also create my own
tag for this purpose.

Any insight, suggestions or anecdotes into these issues would be greatly
appreciated.

Thanks again,
John

Nice attitude. I hope I misunderstood that reply...

Anyway, to answer the original inquiry:
A part of the UI of our app is a flash movie, and we chose to integrate 
it using XML. The Flash sends requests to our struts actions (they look 
like any other URL to Flash), but these particular actions return XML 
instead of HTML. The Flash parses the XML and applies it to the UI 
appropriately. Works quite well and with no noticeable CPU usage on the 
client - a problem we had with the previous, complicated HTML interface 
for this part of the app.
There is also a relatively new feature of Flash MX that provides 
integration between Flash and J2EE apps without using XML in between. 
Although I haven't looked at it in detail, I bet it can be used with 
Struts as well as "ordinary" servlets. See

RE: Flash+Struts how?

2003-01-27 Thread Haseltine, Celeste

I would suggest checking out using Flash Remoting, on Macromedia's web site.
I suspect that is what your client is talking about when they say they want
to do data entry using Flash.  Flash Remoting has about 12 GUI components
that can be used in place of HTML for data entry, and is competitive to some
of MS GUI components.  Macromedia has rewritten the Pet Store application
using Flash remoting, to give people an idea of the GUI components that are
available, and how they can be used.  If you have any trouble finding the
URL's for all this on their web site, post again, and I will send them to
you.

You should note though that Flash remoting does require the use of one of
Macromedia's server packages, such as JRUN server or Cold Fusion server.  I
do not believe that it will run on Tomcat/Apache, but check out their web
site to verify this.  They may have released a server component that will
run on any server since I last research this.

We have developed a Struts application, using this
great framework.

Now... the client wants to convert it to Flash, and do
data entry in Flash.
What is the best way?
We would like to keep our beans and DAO.

RE: Flash+Struts how?

2003-01-27 Thread Robert Taylor

I actually started looking into how I could integrate Struts with Flash.
I wasn't concerned with the server side, I was mainly concerned with how
Flash communicated with the server. I found the following article on
Flash Remoting which was interesting. I appears that Flash Remoting
uses a specialized form of messaging over HTTP to talk to a servlet
which inturn invokes methods on Java objects (hmsounds like Web
Services)

I got side tracked on some other stuff, so that's about as far as I looked.
Here is the article:

http://www.javaworld.com/javaworld/jw-01-2003/jw-0117-flash-p2.html

Good luck.

Can't help chiming in here:  You're not likely to find any metrics like these, and if 
you do, you should only use them the way most statistics are--to blindside people into 
agreeing with your premises.  If you think about it briefly, you'll realize that 
metrics like these will never be that accurate, and even if the metrics themselves 
were precise, they could never accurately represent quantitative differences between 
development methodologies or frameworks.  The reason is simple:  No company ever 
builds the same thing twice and every project is very different.  This makes 
quantitative apples-to-apples comparisons of frameworks/practices practically 
impossible in the business world.  Perhaps an academic experiment with two teams 
implementing the exact same spec. with different frameworks would yield some useful 
information, but any quantitative comparisons you receive from the business world are 
spurious at best.  

You're much better off relying on first-hand qualitative comparisons, e.g. "We were 
using X for web development and now that we've switched to Struts, I don't have to don 
my fire hat on a daily basis to douse that conflagaration we called a web app."
