You just need http://localhost:8080.  Didn't it work?

Re: want to have errors to be dispalyed in diffrent page

[Vivian]

Thank you, Aaron. The explaination is very clear. I still not clear about
one thing. In the following part of your code, you use id="error". Where
should define "error"? I tried to clear it by myself, but it seems not easy
for me to find answer by myself. Please give me a hint.

Thank you so much

regards

Jenny

Re: [I18N] Locale Mysteriously Reverts to null

[David Geary]

Resin 2.1.2. I hadn't thought to try it with another container, so I 
tried it with Tomcat 4.1.3, and it works as expected, that is, the 
locale doesn't revert back to null.

I assumed it was something I was doing wrong, but evidently it must be a 
Resin bug.

Thanks,

[I18N] Locale Mysteriously Reverts to null

[David Geary]

I have an action that sets the user's locale with Action.setLocale(). 
After I set the locale, I verify that it's been set with 
request.getSession().getAttribute(Action.LOCALE_KEY). It has.

Then the action forwards to a JSP page and within that JSP page, the 
locale is null, which I verify with
<%= session.getAttribute(Action.LOCALE_KEY) %>.

How do I make the locale stick, and why does it revert to null?

Thanks,

RE: Java Server Faces and Developer Life Comments

[Bill Willis]

Hi Tiago,

"... I don't understand why IDE like Jbuilder don't come with support
for frameworks like struts. In version 8 or 9 maybe there will be
integration with JSF, by then JSF 2 will be out..."

That support already exists. Try ObjectAssembler, Struts Console, etc.
Remember that most IDEs will give you okay support for ten zillion
different things but rarely deep support for anything. Try one of the
Struts tools that plugs into JBuilder and other IDEs seamlessly and get
deep, intelligent support for Struts. You won't have to wait around for
mediocre Struts support. :-)

Re: Java Server Faces and Developer Life Comments

[Tiago Nodari]

The thing with .NET and Microsoft is that you normally have little choice 
on how to do things; you have all in one IDE, which is something I wish we 
had.  As with J2EE you have tons of choices, is that good or 
bad?  Sometimes I think its what makes developing in java a pain, you have 
tons of IDEs, but none are complete, instead of working together we have 
tons of different open source tools for the same purpose, and each one 
lacks something the other has, which makes me wonder why dont they just 
join forces and create something with the best of the two solutions, and I 
come up with the answer that this is a democracy, and like a democracy, all 
we do is argue, as for .NET you get what they ship out :)  J2EE containers 
have been fighting against each other while .NET has been growing its 
impossible that they didnt see that.

How many frameworks like struts are there?(no need to answer, I now there 
are tons) And now we have JSF, from which I have seen overlaps with Struts, 
and yet its different, here is my point why not use a framework that is 
already out, to make life easier for developers.  The constant changes in 
Java are a real pain, when you finally get the hang of something they 
something comes out that is sometimes totally different.  I like new 
things, but there has to be a limit, we have JSP 2, JSTL, JSF, and etc etc 
etc.  It seems that we need to spend more time finding out what is new and 
out there and less time developing.
And we don’t have a all-in-one-to-everything IDE, we have to hope some 
really nice developer takes the time to develop a plug-in, I don’t 
understand why IDE like Jbuilder don’t come with support for frameworks 
like struts.
In version 8 or 9  maybe there will be integration with JSF, by then JSF 2 
will be out….

Pls don’t flame me :) just my opinion, I know a lot ppl put really hard 
work into Struts, JSF, JSTL, JSP, J2EE and etc.

Re: want to have errors to be dispalyed in diffrent page

[Aaron Oathout]

No problem, in struts-config.xml you should have an action defined like the 
following (different values of course):


 


The "input" attribute is used by the action when validation fails. Instead 
of having it point to "login.jsp" in your case, have it point to 
"errorpage.jsp". In errorpage.jsp, put something like the following where 
you want the errors displayed (this is assuming struts 1.1x, can't 
remember syntax for 1.0, but there is something similar):




   
   
   



Hopefully this helps. Maybe this link will help clear it up also ( take a 
look at section 3.3.4 ).

Re: want to have errors to be dispalyed in diffrent page

[Jenny]

Aaron:

I figure out you must mean this- to change input attribute in
struts-config.xml. I have done this. The following
is part of my struts-config.xml file:




.



  

Note: I have input="/errorspage.jsp". It is point to errorpage, not login
page. But in errorpage, I only get "Please correct the following errors
before you proceed:", there is no specific error message showed, so user
don't know which field is wrong. Does anyone know what could cause the
problem?

Thanks.

Aaron:

Thank you for your reply. But I am not sure I get what you mean. You said
"change the "input" attribute for your action to point to the page you want
your errors displayed on.". In my login.jsp page, I have:
...

..

How can change the "input" attribute to point to my errorpage.jsp. What do
you mean by "input attribute"? Could you explain in a little bit detail?

Thank you very much

Re: want to have errors to be dispalyed in diffrent page

[Aaron Oathout]

Just a guess as I haven't tried this, but it would seem to me you could 
change the "input" attribute for your action to point to the page you want 
your errors displayed on. Anybody thats tried this care to confirm or 
correct my assumption?

want to have errors to be dispalyed in diffrent page

[Jenny]

Dear friends:

I am using struts to develope web application. I use  in
login.jsp, and I implemented validate(..) method in LoginActionForm class.
If user enter invalid username or password in login page(login.jsp), I want
the errors to be displayed in another page(errorpage.jsp), other than in
login page. Is there a way to fulfill this? Your help is appreciated.

Thanks,

Re: Using the template tag library with parameters like jsp:param

[jw]

Hi All

Sorry for the bother - but, who knew - i.e., The issue was apparently
related to the struts "version" I was using (i.e.,
"jakarta-struts-1.0.2")...

Apparently, the examples will work only with jakarta-struts-1.1-b2.At
least in my current environment (winXP/j2sdk1.4.0_01/jakarta-tomcat-4.0.4)

Thanks!

No form parsing when file upload exceeds maxFileSize

[Wellie W. Chao]

I have a form with several  input fields and a couple of
 input fields. In web.xml, I also specify a value for
maxFileSize (currently set to a really small value of 5K for testing).
Here is the portion of my JSP with the input form:

-



Job Name:
Job Type:
Due Date:
Thumbnail 1:
Thumbnail 2:
Thumbnail 3:
Thumbnail 4:
Thumbnail 5:



-

My action class uses the actionClass hidden variable to determine when
to display the input form vs. when to process the inputs.

[1] If I enter valid inputs and upload a file smaller than maxFileSize,
everything works fine.

[2] If I enter an invalid input and upload a file smaller than
maxFileSize, the input page gets redisplayed with the form errors at the
top, which is also fine.

[3] If I upload a file larger than maxFileSize, the problem occurs. I
don't get the actionClass form variable set. None of the other form
variables are set either. Thus, the input page redisplays as if the user
just pulled it up. None of what the user typed before is preserved, and
even more importantly, the user gets no indication that it was the size
of the file that caused the input page to redisplay. In fact, the user
gets no mention whatsoever that an error occurred. It just appears to
the user that the application has a bug and is being stubborn.

How do I get the values that the user entered (and also the hidden HTML
fields) when Struts detects a larger than allowed file in a file upload
field? I don't seem to get any indication that Struts decided not to
parse things because the size of a file upload field exceeded the
maxFileSize setting.

multiple html:select boxes on the page

[Hemanth Setty]

Hello,
I am trying to figure about a good way to use multiple select boxes with the
same data on the same page. The page contains
and bunch of questions and select box with the type of question(EASY,
MEDIUM, HARD). The question are variable and I get them from the database
along with the type for the question. The problem I am having is this, I
cannot define multiple select boxes with the same name using a DynaForm. I
could use the DynaForm.get(i) method to get a particular index of value.
But is the order of parameters coming from the page guranteed to be in the
same order as the values that were set on the selectbox?
Ex

Q1 Blah Blah?  ...

Q2 Foo bar ? ...

Before the page get displayed i will get the form and set("type", 1,
"EASY"); and set("type", 2, "MEDIUM");

When the page shows up, I assume the order will be in the right order..

Now when I click on submit on the page..will I get the Q1's type in
get("type", 1) and q2's type in get("type", 2)??

Another alternative, not very elegant though, is to have a hidden fields
associated with each select box and the value of the hidden field will have
the name of the select box. Then use the http request object to get the
value from the select box. But this way I cannot use form beans to manage
the select boxes..because the names on the selectboxes will be dynamic.

A good way that would be nice is to have the dynaformbean take something
like this

 and ..to 
will automatically work with get("type1")... get("type5")...etc...
Maybe im going a little overboard here...I think the DynaBean will not
support that.

So anybody enlighten me a little bit here?
Thanks in advance and have a good weekend..for those of you celebrating
Labor Day

Ummm... What am I missing? Sounds like they are using Jato instead of
Struts, but I'm not seeing a GUI environment, just a really crude
NetBeans integration... Did I miss a link or something?

Instead of using getMessage(key, arg0, arg1, etc, etc

use getMessage(key, args[])

The default implementation of MessageResources (PropertyMessageResources)
does not provide for any way to manipulate the underlying HashMap at
runtime.

However, I guess you could hack around this with your own implementation
(not recommended).  Myself and a few others are looking at creating a
JDBCMessageResources that will probably provide a reload method.  So, I
guess, in a way that would allow someone to modify at runtime.

Re: [VALIDATOR] Bad Error Message when Validating a Range

[David Geary]

Thanks for the suggestion, but that didn't work either.

It's strange because I'm validating other fields in the same form and 
the error messages are correct for those fields. Also, If I change the 
range message in the resource bundle, that change is reflected in the 
message, but it always displays null for both the min and max values, 
even though the validator correctly uses those values to perform the 
validation.

Yes. Use the direct attribute, like this:



Then in your template, you can access that value; for example, like this:

...

Normally, the  tag will include content associated with 
the named parameter, but if you
specify direct='true' with , the  tag will 
just retrieve the value.

See http://www.javaworld.com/javaworld/jw-09-2000/jw-0915-jspweb_p.html 
for more information about templates and the direct attribute.

btw, if at all possible, I suggest that you use Tiles instead of 
templates. The former, which is an extension of the latter, has more 
functionality.

No, but you can use  as illustrated above.

URGENT!!! Dynamic parameters in App Resources for error handling

[Tarun Sainanee]

Hi all,
I have been pretty happy using struts 1.0.2 for some time now. But now i 
have a problem. Please help.

I know that we can user parameterized messages in the App Resources file 
for error messages. Depending on the no of parameters i can have an 
errors.add() method pass the parameters.
But the problem is that i do not know in advance how many parameters i may 
need to pass? Any workaround guys?

Also is there a way that i can access the message in App Resources File 
and modify it at runtime???

Pointers to a working code would be excellent.

Ummm... What am I missing? Sounds like they are using Jato instead of

Interesting comments. As for this one above - I agree. You have to go
where the money is when you are consulting. I co-founded a Java-focused
consulting company and have since pursued other things, but have noticed
that they are starting to do .Net training (internal and external) just
as we did Java training back in '97, '98 when Java 1.0 and 1.1 was
starting to gain favor. It's the only smart thing to do. Hope all goes
well with your business..

James

I use DispatchAction almost exclusively. Each subclass of DispatchAction
serves as a proxy to a set of related events. So for example, if my
site had a user account section, a store section, a product section, and
a support section, I would have AccountDispatchAction, StoreDispatchAction,
ProductDispatchAction, and SupportDispatchAction. Each DispatchAction
operation delegates to the appropriate business service where all the
processing take place. In this fashion, I reduce the number of physical
Action classes that really cannot be reused. By grouping them into
related event handlers they become more cohesive and easier to maintain.
By delegating to business services, I can leverage reusable business
components.

As far as ActionForms. It is quite simple. I have a single
DynaValidatorActionForm per DispatchAction. It contains all the fields
that
will be used to process the related events. Since they implement
the DynaBean interface, I can simply pass the DynaBean to my business
service and remove any business logic from the DispatchAction class
without fear of coupling the business layer to the web layer.

As far as validation. It is also quite simple. I leverage the use of
Struts validation and identify the fields to validate using the action
mapping path +
the operation which uniquely identifies the fields to be validated. Very
clean.
So I end up with something like the following in the name attribute of the
form
element in the validation.xml file.

Re: Java Server Faces and Developer Life Comments

1. NetDynamics is alive and well, see:
http://developer.iplanet.com/tech/appserver/framework/index.jsp
They have a nice sample app as well.
But since I Planet has a bad rap, so does the Sun framework.

2. .NET can be improved via a MVC framework, Maverick. (most of you know of
Maverick as a Struts competitor)
http://mavnet.sourceforge.net/
There are lots of .NET versions on sf.net of Jakarta type tools for .net
(Like JUnit, etc.), just search sf.net
If your goal is to generate profit, M$ looks good (they are inexpensive and
productive).
A neat feature of .NET is webForms, they are neat.

Also, C# is a ECMA standard and here is the open source version:
http://www.infoworld.com/articles/hn/xml/02/07/22/020722hnoreilly.xml

And most important, MS is MUCH cheaper than BEA or IBM J2EE servers.
(Sun does not care about this. Sun is interested in selling $500,000
SlowLaris machines that are slower sometimes than $2,000 Linux machines. See
tpc.org.)

3. These people claimed that they are the reference implementation of Java
Server Faces (and I mentioned it to the JSR and now they backed of a bit,
but I suspect that they have something to do with Sun on JSF)
http://www.qbizm.cz/newsletter.html
( I looked at it and was disappointed so I as well wrote a letter to the JSR
for what it's worth. My point was the same, Struts is more productive.)

4. Corporate developers need GUI IDE. Things that expand the tag in JSP.
Things that bind text fields to Bean. IBM is one IDE that does most of this.
However, commercial developers, need to be able to get to the code. It is
possible to do both.

slow
HW. I think they will go the way of Digital, Data General, MIPS, etc. and
fade away.
Let Sun go out of business, we will take the licks, and then compete.
This IMHO is good for Java, Java without SUN (we have IBM VM, Jikes, open
source Java, many Java alternatives). This would allow Java to compete on
SW. (and anything that was meant to sell more HW, such as EJB or the web
server + app server + EJB server concept goes out the door, Tomcat or Resin,
etc can do all 3 just fine. I found EJB limits the number of concurrent
users you can have per box severely compared to other DAO implementations).

c. I have urged my clients to stop using SUN VM and use the faster IBM VM.
(Sun has GC and other issues under load. There are lots of faster VMs, like
JRockit or TowerJ) My clients, some of them quite large are leaving Sun HW
and Sun Java to Linux and IBM VM. Other example is the Apple Java on OS X.



I. I think .NET is better than J2EE. However, open source is better than
.NET.

II. I have tried to create a competitor to ADO, using a DAO design at
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/basicportal/src_05d/basicPort
al/src/org/apache/commons/DAO/ (basicDAO)
Idea is that you can implement a DAO interfaces using JDO, EJB (if you are
new to J2EE, people first try EJB on their first J2EE project, then never
again), RowSet, OJB, or any other way.
This way, it is easy to change how your DAO is implemented. (my
implementation uses Disconnected RowSet)

III. Still the best practice, better than .NET is to use Struts, with JSTL,
with Tiles and with DAO interfaces. I tried to document best practices for
web site development and implement those in code at basicPortal.sf.net.
(it uses for example declarative security and has verticals samples)

Feel free to contribute to free and open source "best practices" for web
development.



To me this is similar to this:
Oracle is more complex and more expensive than MS SQL. So M$ SQL is better.
However OpenSource PostgreSQL is better and cheaper than M$SQL.
J2EE is more complex and expensive than J2EE (IBM, BEA, EJB). So .Net is
better. However, OpenSource Struts + JSTL  is better and more productive
than .NET.

Or Windows vs Linux. Problem is that managers are scared of Linux and
managers are scared of Open Source.
http://www.opensource.org/advocacy/case_for_business.php


My conclusion: If .NET or C# or anything becomes more prodctive than Struts
with DAO, I will switch. I chase profit, and profit to me is showing clients
how they can develop fast and productive for very low cost, and operate high
volume at low cost. Open Source beats .NET. However is there is more high
end consulting in .NET... I have to switch.

VLR (very large resultset) problem : just an idea

[flare]

Ok, I know anyone has a custom solution for this very problem but I think we should 
find a 
general one, why reinventing the wheel? We've a couple of great paging taglib so I 
think 
we need to interface to them instead of recode everything.

1- The taglibs need the data stored in the session (which is not that bad, perhaps it 
doesn't 
scale exceptionally) 
2- The data should be a collection of beans (usually) 
3- the user really doesn't need more than 15/30 records at once

so I think we need to code a "virtual collection", this object simulates millions of 
records but 
only has 30/40 records cached, when the taglib request a record and the collection 
gets a 
miss (a not cached data) it should retrieve new data from the db (using the 
application db 
pool), same thing when the taglib request a sort.
The code should be general enough to interface to various db and pools.

What do you think?

Extending the scope of the struts validation
From: Frangois Rey
Subject: Extending the scope of the struts validation
Date: Sat, 23 Jun 2001 07:32:15 -0700

You may remember some of my earlier postings about a mapper framework that 
we use as a
validation framework. I now have the support in my company to make it open 
source.
However, I first would prefer to:

1- Invite the community to realize that a validation framework, definitely 
required in
Struts, is only part of a larger requirement.
2- Propose the extension of the scope of the TO DO item for validation so 
that is does
a bit more than just validation but also convert the value and transfer 
them to where
they should end up.

I know I've already approached this topic in my previous postings, but I 
there hasn't
been much follow up on this. However I still believe those that have 
developed web
applications with Struts have been confronted to the same problems we have 
been trying
to solve. So instead of submitting a big zip file that may or may not get 
interest, I
first would like to share the reasons that led us to developing the mapper 
framework.

In our company, after evaluating a few options, we have chosen Struts as 
the base
framework for developing web applications. We have developed our own simple 
extensions
to Struts in order to provide added support for things like i18n and 
transaction
integrity. Form validation was also a top item in our list of needed 
extensions, but
looking at the Struts 1.1 TO DO list we decided to wait and see what the 
community
would come up with. For one of our customer project, we have looked at the 
validation
framework from David Winterfeldt in order to implement form validation. We 
were very
attracted to that framework because it offered configuration-based 
validation and also
client-side validation. However beyond the simple need to validate form 
properties, we
also needed to do type conversion (text->object) on each field and populate 
another
bean (a command bean) with the converted values. Having a framework that only
addressed the validation part meant that we would still need to do a lot of 
custom
coding in order to convert values and populate our command beans. And in 
addition to
this, we also needed to do type conversion and populate presentation beans 
when
receiving result messages from the backend, which means even more custom 
coding.

I think by now you should understand and hopefully agree with me that 
validation is
actually only the first part of larger need: once values have been 
validated, you need
to do something with them. Whatever is needed to do, it should not be the
responsibility of the ActionForm. The latter should remain a View object 
that is only
a placeholder for user input. Business logic should be separated into 
another set of
objects. Actions seem to be a good place for implementing this business 
logic. However
doing so ties the logic to the web application framework in a way that 
makes the reuse
of this logic outside of a web application difficult. So a good application 
architect
would usually factor this business logic into another set of objects that 
is not
dependent from the web application. Often these objects are actually just 
sending
requests to a backend where the real business logic resides. But whatever 
these
objects are (the real Model, a PreparedStatement, or a proxy to a Model layer
implemented on another server), the point is that these are objects which 
need to be
initialized and populated with the user input.

Coming back to our project: we have an EJB backend accessed with a messaging
framework: you send command messages (objects), and you get result messages 
(objects).
And of course we wanted to avoid lots of custom code in our actions because 
it's
tedious, not so fun to write, and increases the maintenance burden (more 
lines of
code). So we took the decision to develop the mapper framework. What we now 
have is
used almost all over the place in the application we're developing, for the 
things I
mentioned above: validation, type conversion, and bean population, and for 
both
directions: forms -> command messages and result messages -> presentation 
beans. The
code in our Actions.perform() has decreased dramatically to just a few 
things. When we
get to the Action, the ActionForm.validate() has successfully validated the 
user
