RE: Technical question about Struts Workflow Extension

[shirishchandra.sakhare]

Hi,
We have just created an account with source forge for the workflow extension project 
and will be transferring the source code etc. to that account  in the next couple of 
days.
So we are just in early stages of code transfer.
 
But regarding your question.
 
As you said,most of the workflow information can be made available for reading 
atleast.And I had came across similar problem and mr.Matthias bauer had replied that 
it was just overlooked.As this extension was developed/modified as and when the 
requirements arose, it does not have all required extension points and public API.
 
So that is the first task I am going to undertake.To see what parts of workflow can be 
made public and where all extension points are possible so that users can customise 
behaviour of the workflow.
 
And I am planning a next release very soon ,But have no definite schedule.But I am 
really looking forward to getting more such ideas /requests so that the next version 
can be designed keeping into view all of this.
And your requirement has just given me the idea for next immediate release.First thing 
I can do is to atleast make all Workflow state available in readOnly mode so that 
existing users can access use this  functionality without breaking any of the workflow 
logic.
 
Any ideas/suggestions are welcome.
 
I am forwarding this mail to struts user list so that others can also contribute to 
this discussion.
 
regards,
Shirish.

Subject: Technical question about Struts Workflow Extension


Dear Struts Workflow Extension team:
 
I'm Ignacio Cruzado, from Spain, computer programmer who works on Tecsidel SA (a 
programming company) as a computer consultant.
 
Matthias Bauer gave me your email address in order to redirect this technical 
question... I hope to be writing to the right person (I'm sorry if you are not this 
one!).
 
We are using "struts workflow extension" (SWE) in our development, and we would like 
to access the mapping information that SWE clases manage (the dependencies modelled in 
the struts-config.xml file).
 
In your "Workflow scope" web page you only provide information about the Primary 
Workflow and it's state.
I would find very valuable to have methods to access also to the dependencies of the 
actual state: nextState, prevState, isEndWorkflow and so on...
I have been studying the source code of SWE and I have found out that this information 
is managed by the SWE, but not published (most methods and data structure that manage 
the mapping are on the private/protecthed/package scope, instead of the public scope 
(where I would love to found them!).
Why SWE API design doesn't publish that information? Is there a technical reason for 
that? I'm talking about just readding (get) not establishing or manipulating (set) 
that information.
 
I know that we can change the source code, in order to "open" that information, but 
before doing this I would like to ask you to put much more getter methods in order to 
ask the SWE about the workflow mapping that the developer has established, and get 
more information about the actual state of the workflow.
 
Are you working on that? Is a new release of the SWE scheduled? Is it going to have 
new functionallity in the way I'm asking for?
 
Best regards,
 
  Ignacio

ok, got it. and i have done it. 
but now the problem is retrieving my component from the context.
in my Action class there are no references to ActionServlet, and thus
i cannot get the ServletContext from anywhere...

any help?

The struts-config.xml file is processed when the init() method of the
ActionServlet class is called.  In turn, that happens at one of the
following times:

* If you have declared a  element in web.xml,
  this will happen before the web application is made available
  for use by clients.

* If you have not declared a  element in web.xml,
  this will happen on the first request with a URL that is mapped
  to the Struts controller servlet (typically something like foo.do).

If you are in a Servlet 2.3 (or later) environment, using a
ServletContextListener is the guaranteed way to ensure that your
initialization code is run prior to application startup.  Struts 1.1 is
still compatible with Servlet 2.2, however, so this was not an option
available to Struts itself.

The advantages to using the struts plugin are that it gives you access to
struts configuration information, and that you can control the order in
which your plugins are initialised from struts-config.
Does the access to the struts-config occur in a static initializer block 
 or method?  Or does it occur in an instance-specific block of code 
(constructor, instance method, non-static initializer, etc).

RE: question about struts

[Bailey, Shane C.]

I just posted (yesterday) a code example of how to extend the ActionServlet.
It is a piece of cake:

http://marc.theaimsgroup.com/?l=struts-user&m=105476124906048&w=2

And I found another post while looking for mine:
http://marc.theaimsgroup.com/?l=struts-user&m=100500141726722&w=2

And here is a thread about whether to do it or not and other stuff:

Subject: question about struts

hi all,
i have been working with JSP model 2 for few years, and now i want
to move to struts.
i am starting to get acquainted with it, and i need help to face this
situation.
in my mvc, i am using 2 components, one to connect to R3 and the other for
connecting to DB.
the lifecycle of those components is the same as my servlet, since those
components are not
user/session/request specific.

in reading docs about struts, i could not figure out where to put those
components in the
struts framework. of course, i can put them in ActionServlet, but this will
require me to modify the
code of the ActionServlet.

is there any other way to do that other than modifying the code of
ActionServlet?

hope someone can help...

thanx in advance and regards
marco

You can use a Struts PlugIn to initialize your components and store them in 
the ServletContext.

RE: question about struts

[Andrew Hill]

The differences are not much - both are probably equally usuable in this
case.

The advantages to using the struts plugin are that it gives you access to
struts configuration information, and that you can control the order in
which your plugins are initialised from struts-config.

RE: question about struts

[Andrew Hill]

The ActionServlet has a reference to the servlet context which may be
retrieved using:
servlet.getServletContext()
Using the servlet reference passed to your plugins init() method.

Your plugin would initialise those objects you want stored in the servlet
context, and then store them there. The plugin itself doesnt need to be
stored as its job is just initialisation.

and
'At runtime, any resource setup by init would be accessed by Actions or

Depends.
Your session could be tied to a cookie, in which case two browsers
probably won't share the session (usually you have separate cookies for
each browser instance, i.e. process, but that depends on the browser).

If you just open another browser window chances are that cookies are
shared between those windows; depends on the browser, though.

Your session could be tied to the URL (i.e., the session ID is part of
the URL), in which case the session would be shared when using the same
URLs, no matter if you're using a different browser, different machine
etc.

Check the servlet spec.

Re: What is UserDirectory?? (Question about "Struts In Action" by Husted)

[alexj]

As it's write on the book it's an helper class who provide an action to
store the
key user name and password into a file.

An helper class abstract the logic for an action. But as you can read
on manning web site on errata part :

The test doesn't mention that the UserDirectory source code is available in
the download. The following should be added as the second paragraph of page
20:

  "We will also focus only on the Struts source files you need to create.
For example, the UserDirectory class is part of the application's business
logic. The Struts framework interacts with this class, but the UserDirectory
is not part of the Struts layer. (You would need this class whether you used
Struts or not.) If you are interested, the source code for UserDirectory is
provided in the WEB-INF/classes folder of the register application."

Question about Struts and HttpSession management

[Heligon Sandra]

I know the definition of a HttpSession but I don't understand well
how
this object is managed ?
Who is responsible for the creation of the HttpSession ?
If two clients use the same machine did they share the same
HttpSession ?
If two web browsers are opened on the same machine, did they use the
same HttpSession ?
I don't understand well the creation or delete of an HttpSession ?
when did they occur ?
The delete of the HttpSession is done when the servlet engine is
killed, or when the session
timeout is reached. But are they others reasons ?
Nothing is specific to Struts for the HttpSession delete, isn't it ?
Concerning the creation of the HttpSession and the association with
a specific user or machine
I don't understand large time there.
Is Struts there for something?

Student question about struts

[Jobe, Mike [EESUS]]

Hey all,
I am working on my senior project at school and I need to make a dropdown
box and a list box. What is the easiest way of doing these? I will be
connecting them to the database later, so all I need is help with the actual
layout.

Thanks!
Michael

Craig,

One thing that I do not understand is the property `key' 
of the method ``ActionErrors.add( String property, ActionError error )''.

Most people use ActionErrors.GLOBAL_ERROR anyway. What was 
the original design decision to store error message for
each property?

Best thing to do is submit the change now.  I've already been committing
little changes as a result of comments on the user list the last few days
(i.e. in tonight's nightly build you won't find LogonForm.java any more,
or the comment about tools that you found confusing).

Changes to improve the clarity of the examples are much more likely to get
in, because there's no risk of destabilizing the framework code itself.

Ahhh... didn't realize that.  Basically, I posted my code, which was adapted
from the example, and somebody asked why on earth I was doing that.  I
pointed at the example, and was told that it would NEVER happen.  So I
believed them, and took it out.

As for working on the example... would any changes have a chance of getting
committed before 1.1 final, or should I just wait until that's finished?
And what does the diff look like for *removing* a class-- as I understand
this, the LogonForm.java shouldn't even be in there now that
struts-config.xml is set up to automatically generate the form bean.  My
limited test shows that the example works fine without it.

And if this happened, what would mapping.getAttribute() return? Assuming it
would be null, I'd expect the setAttribute call to blow up.

Yep ... that's how.  Struts will use introspection to tell whether your
form bean class is a DynaBean or not -- specifically, look at the
setType() method of org.apache.struts.config.FormBeanConfig to make the
determination whether your bean is dynamic or not.

Wow... I just deleted the LogonForm.class file under the 'classes' directory

to the form in struts-config.xml, and to logon.jsp, reloaded again, and my

Confused again.  (I will need a custom validate method.)  How does Struts
know to start with my class that extends DynaWhateverForm and add the stuff
in the  tag to it, rather than creating a new one?  Would it be:


and then
  package edu.asu.vpia.blah.blah;
  public final class LogonForm extends DynaValidatorForm { ... }

??

Don't feel bad!!!  None of the developers who have been around forever can
see things from a newcomer's viewpoint as well as we'd like -- getting
called on stuff like this is the best way to get it improved.

Actually, there *is* a case when form will be passed as a null -- if
someone were to modify the struts-config.xml entry for this action, and
accidentally (or on purpose) remove the "name" or "attribute" attribute.
Then, the controller servlet would assume that no form bean needs to be
created, so it won't do so.

So, this particular code could be called paranoid, but I'd rather protect
myself against my own mistakes (or mistakes by others on the team) and
avoid the possibility of a NullPointerException due to misconfiguration.

Note that this kind of a problem could not be detected at compile time, or
even by static examination of just the Java code, and is also unlikely to
be the sort of thing that unit tests would try to catch (how many people
write unit tests with purposely broken struts-config files to see what
breaks?).

If this were a real production application, would you rather find out
about it when a user reports the ugly stack trace that would result, or do
you want to spend a little time preventing some types of problems from
occurring in the first place?

We can add comments if you want, but at some point it also becomes an
issue of personal programming style as well.  Over the years, I've shot
myself in the foot enough times that it's embarrassing to think about.
Because of that, I've developed some personal coding habits to try to
minimize the possibility.  And, if you read TOMCAT-USER, you'll find that
unexpected NPEs is a *very* common problem for newcomers to O-O languages.

Yep :-).

On a Unix platform (or Windows with CYGWIN), "diff -u" is the best way to
prepare a patch.

But messing around with it can be a really useful way to learn :-).

And don't worry about breaking it for everyone else -- part of a

I hate to complain, but the example really is confusing.  It also has a
bunch of code that makes you think you need to instantiate ActionForms
yourself:

  if (form == null) {
form = new SubscriptionForm();
if ("request".equals(mapping.getScope())) {
request.setAttribute(mapping.getAttribute(), form);
} else {
session.setAttribute(mapping.getAttribute(), form);
}
}
SubscriptionForm subform = (SubscriptionForm) form;

when I've been reliably informed (here!) that execute() will never, ever be
called with a null ActionForm parameter.

I realize that code may just be there to make triple sure that the example
will not fail to run, but it could at least have a comment to explain that.

I know, I know... submit a patch. :)  I'm getting closer to figuring out how
to do that, but I'm not quite confident enough yet to mess around with what
is held up as "The Struts Example" app. ;)

That precise comment is a carryover from Struts 1.0 days, when there was
no such thing as a DynaActionForm.  The theory was that you could document
the properties of your bean in struts-config.xml and then write a little
tool that would generate an ActionForm class for you.  DynaBeans make that
approach unnecessary for form beans.

Again, that's a carryover from the 1.0 (pre-dynabeans) approach.  We
should definitely clean this up to avoid confusion.

For this specific case, there is no reason to have a LogonForm class at
all, because the default behavior of a DynaValidatorForm (which is a
DynaActionForm plus using the validator framework to define validation
rules) does everything you need.

The only reason you would ever need to create a real class that extends
DynaActionForm or DynaValidatorForm would be if you need a custom reset()
or validate() method.

Question about struts-example struts-config.xml

[Wendy Smoak]

This appears in struts-config.xml in the struts-example webapp:


What is the "generator tool" it's talking about?  I'm just starting to
experiment with dynamic forms and I'm not sure if this is an old note or
something important.

And then I'm confused by the fact that the  tags are in
struts config:


  
  


But they are ALSO in LogonForm.java:

public final class LogonForm extends ActionForm {
 private String password = null;
 private String username = null;
 public String getPassword() { return (this.password);  }
 public void setPassword(String password) {this.password = password; }
 public String getUsername() { return (this.username);   }
 public void setUsername(String username) { this.username = username;
}

I thought they "Dynamic" part would generate the properties and get/set
methods based on the  tags and eliminate the need to code
those in the Form.  Andy why doesn't LogonForm extend  a DynaActionForm (?)
instead of plain old ActionForm?

Confused...

It's because of the "indexed" attribute on tags inside the "logic:iterate" element.  
That won't work (I believe) with "c:forEach".

Re: A question about struts ?

[Eddie Bush]

"... the expert group can be found at Struts ..."

Which expert group are you refering to?  If you're looking for a spot to 
get quick, high-quality feedback on your Struts problems, this is the 
place.  If you're looking for a spot to gain access to any of the EGs 
concerning some certain JSR, Craig R. McClannahan is on the list -- but 
depending on which EG you need access to, it might be better for you to 
ask your questions in a different list.

A question about struts ?

[Zahid Rahman]

Hi,

I was informed that the expert group can be found at Struts,
as I am interested in building applications which support
business critical processes.

Is this the struts group  ?

I have no question on the implementations because the documents I have seen
so far
are very nicely structured.

It depends on how complex of a change you want to effect.  You can add 
actions to the configuration without having to write a single line of 
Java code - Struts provides some nice default actions to serve this 
purpose.  If you need to add processing of some sort or another then, 
yes, you're probably going to have to know some Java.  I should say 
though, that the complexity of the Action classes you write will be tied 
to how well you move your logic into beans (how well you abstract your 
operations).  If you give your end-users a nice facade to work with, I 
wouldn't think it would be very complex programming - but it also will 
depend on the nature of the task they wish to implement.

Struts, Tiles, and the Validation Framework are all configured (almost) 
exclusively by their respective XML configuration files - and those are 
easily understood, even by folks that don't know XML as more than "a 
slightly different HTML" (aka ME).  Bear in mind that you could always 
build some interface to manipulate this for your end-users if you felt 
the need.

Go check out Chuck's book to see what Struts can do and how easily it 
can be configured.  If you have specific questions about "Well, would my 
end usrs have to program to do ?" just swing by and drop us a note. 
 There are a bunch (understatement!) of talented folks on the list that 
aren't scared to give their opinion.  Oh, and you might also search 
"oreilly.com" articles for "rolling blogger" to give you some ideas of 
how you can automate Struts configuration type things.  I haven't looked

Simple question about Struts

[E. Laverdiere]

Hi all,

I've studiing Struts for the past 3 weeks because I have done a generic Jsp
"content-management" web site connected on a MySql database using a set of
custom tag libraries following the Manning book "Tag Librairies". So I am
still new at Struts, and I would like a simple advice over the Struts
framework. I was hoping to adapt my site to a Struts framework to gain some
architectural strenght and, by re-using the work I've done with Strut, I
thaught, limit the future development when doing another site with the same
framework.

My question is : Can a Strut web site be modify or upgrade without the
outcome of a java programmers? I means without the creation of multiple java
classes? It seems that if you want to add a page, or modify the parameter or
the validation of a form, you must go into the java classes that controle
this form and add some logic into it. Without questioning the strength of
MVC, in a first glance, it seems that this framework is not light-weight and
demands some real professional effort to adapt or modifie any web solution
using this structure. So, maybe, loosing the goal of building a generic
solution?

Re: Question about Struts and XSL

[Jeff Pennal]

Josh,

stxx (http://www.openroad.ca/opencode/stxx) may be able to help you with 
your problem.

stxx allows you to take the output of an Action class and process it 
through an XSL file to get the final HTML output, giving you the choice 
of bypassing the JSP taglib specific code of a normal struts application.

If you were to move the logic of the JSP file into an Action class you 
should still be able to maintain the exact same XSL file (w/ form elements).

Check out the examples in the stxx download. Hopefully, they'll be what 
you're looking for.

Re: Question about Struts and XSL

[Eddie Bush]

That's a pretty terse description of your problem :-)

I would build a simple test application first off - get familiar with 
the functionality Struts offers.  Be sure you make reference to the 
chapters Chuck put up for review on theserverside.com!  I think what you 
will find (unless I miss my guess) is that you can, using core Struts 
functionality (DynaThis and DynaThat!) quickly/easily refactor your 
application into something much better.  Not knowing much about XML, I 
can give you exactly zero guidance there.  You know your application 
better than any of us do - sit down and build a small-scale replica 
using Struts to force yourself to learn Struts.  Once you have done 
that, and have more specific questions, I think posting them here would 
get you more helpful responses.

Regards,

Eddie

Question about Struts and XSL

[John Owen]

I inherited an application that uses a Model-1 MVC approach. I was hoping to 
migrate the application to the Model-2 approach that Struts offers. My 
problem is that a particular jsp page uses xsl to render a form and its 
elements. This particular page is the heart of a module that performs 
several tasks and I am unsure of how to proceed. My concern is that I will 
have to completely re-design the jsp/xsl combo to remove the form elements 
from the xsl in order to use the Struts html taglib and Action/Form classes. 
I was hoping to move code that resides in the jsp page into an Action class.

I looked through the message archive here briefly and found a few posts 
about stxx (I think), but I'm not sure it would help without a re-design. 
Any ideas or alternate approaches would be greatly appreciated.

Re: Newbie question about struts and Tomcat 4

[Dick Starr]

Tony:

I thought the default port was always 8080. In any event, you might prove
Tomcat is running OK by entering http://localhost:8080/  (or whatever port
you are using). Then try the struts-example. If that doesn't work then I
would stop Tomcat, erase the tomcat /work/localhost/ directory then re-start
Tomcat (forces re-generation of the work jsp's).

By the way, I posted a problem Friday morning where Tomcat 4.0.2 did
"Marking servlet action unavailable" when I definined a data-source in the
config. I didn't receive a response and don't know why it happened, but did
discover that Tomcat 3.3a worked fine. For now, I am forced to go to 3.3a,
but I can't believe that Tomcat 4.0.2 is broken.

RE: Newbie question about struts and Tomcat 4

[Tony Ziolkowski]

Well let's see what more I can add. I took the .war files from the struts
installation and copied them the /var/tomcat4/webapps. I restarted tomat.
When I enter http://localhost:8180/struts-example I am told that tomcat
can't find the page /struts-example. And I know that http://localhost:8180
IS the correct tomcat port.

That enough detail?

Question about struts and list caching?

[Alex Colic]

Hi,

hope someone can help me out here. I think I have a problem with struts and
my classes caching list.



In my jsp I have some data that is displayed regularly. Therefore I have put
that object into the context via:

context.setAttribute("CommonProblemList" ,tbeList );

When the data the list is based upon changes, I have a monitor class that
listens for that change and then repopulates a similar object and then puts
it into the context via the method/line above.

Then in my JSP I access the data via the below:

  


  

  
  

  

  

My problem is that if I change the data in my database the data in my JSP
page is not updated. I have stepped through my code and my monitor class
does see the change in the database, it is compiling a new object and it is
placing it into the application context. I checked the object data being
placed and it does have the new data in it but if I got to the web page
which uses that object it only shows the old data. If I shut tomcat down and
restart it I do see the new data.


Can someone suggest what is going on here and how to fix it?

Thanks for the help.

Re: question about struts

[Stanley Tan]

Dear Sir,

I believe that if you downloaded the Struts framework, then you have 
already downloaded the documenation.  Let's say you unzipped Struts at 
c:\jakarta-struts-1.0-b1.  If you go to c:\jakarta-struts-1.0-b1\webapps, 
you'll see a file called struts-documentation.war.  Copy this file to your 
Web Server's "webapps" directory.  In Resin, for example, that would be 
c:\{resinhome}\webapps.

You can then view the documentation by going to
http://localhost:8080/struts-documentation

Hope this helps.

Re: Question about struts application model (DataSource, Business Logic beans)

[Ted Husted]

Struts stores the JDBC Connection pools as servlet context attributes
(in JSP terms, application-scope beans). You can also access them that
way. If you do not specify a name in the Struts-config file, it uses a
constant value. If you specify null to findDataSource(), it uses the
same constant. But you can also access the pools using your own labels
(or the Struts constant) without using the servlet method.

Question about struts application model (DataSource, Business Logic beans)

[Carles Pi-Sunyer]

Title: Question about struts application model (DataSource, Business Logic beans)





Hi,


I'm using Struts for a new application that I'm developing. I have a question about the separation between the Action classes and the Business Logic beans. 

My Business Logic beans are making database accesses to manipulate the underlying data model. I am planning on using the struts db connection pool, which is supplied through the DataSource. My problem is that access to the DataSource is through the servlet.findDataSource() call. How do I make the Business Logic beans unaware of the servlet/http layer (as suggested in the developers guide) while still making the DataSource available to the Business Logic beans? Do I have to pass a reference to the DataSource on every call the Business Logic beans (not an option that I like), or is there a cleaner way to do this? I also have a similar issues with logging services.

I believe that a common way to solve this problem is to bind the DataSource to a jndi service. I am using tomcat 3.2.1, and I don't believe that this functionality is supplied in either Tomcat or Struts.

Thank You,
Carles

Binding the data source to a JNDI context is definitely attractive -- and
it is also the approach that is suggested if you are running in a
J2EE-compatible application server (which is required to support this
approach).  In such a scenario, you would configure the data source using
the tools provided by your app server, rather than declaring it in
struts-config.xml, and you'd define a  entry in your web.xml
file to link the data source you need to the facilities set up by your app
server.

Tomcat 3.2 does not support a JNDI context for this kind of thing, but
Tomcat 4.0 does.  By default, it uses the data source and transaction
implementations from Tyrex (http://tyrex.exolab.org), but you can also
create your own object factories if you want to do something different.

Re: Question about struts application model (DataSource, Business Log ic beans)

[Michael McCallister]

I resolved this by creating two pieces:

First is a class in your business logic package that manages the context 
required by the business logic beans.  This class should be a Singleton and 
should manage access to resources needed by your business logic beans such 
as configuration parameters and your DataSource.  I modeled my context 
object after the Servlet session API, but you could make it much more 
structured if you like.

Second, depending on your servlet environment, create some mechanism to 
initialize your application context object.  Using Tomcat, you could do 
this using something like the DatabaseServlet from the Struts example.  In 
this case, your DatabaseServlet gets started by the servlet container and 
it initializes your application context object (using servlet 
initialization parameters, things like a GenericDataSource object, 
etc.).  Now when your business logic beans are called, they retrieve the 
application context, ask it for a DataSource, and use it to get a connection.

When you decide to re-implement your application as a two-tier 
Client/Server application with a Swing front-end, all you need to do is 
implement some alternate method for your application context object to be 
initialized and your business logic beans are shielded from the change.

I'm not sure this is the best way to decouple your layers, but it's what 
I've come across so far.

Title: Question about struts application model (DataSource, Business Logic beans)





Hi,


I'm using Struts for a new application that I'm developing. I have a question about the separation between the Action classes and the Business Logic beans. 

My Business Logic beans are making database accesses to manipulate the underlying data model. I am planning on using the struts db connection pool, which is supplied through the DataSource. My problem is that access to the DataSource is through the servlet.getDataSource() call. How do I make the Business Logic beans unaware of the servlet/http layer (as suggested in the developers guide) while still making the DataSource available to the Business Logic beans? Do I have to pass a reference to the DataSource on every call the Business Logic beans (not an option that I like), or is there a cleaner way to do this? I also have a similar issues with logging services.

I believe that a common way to solve this problem is to bind the DataSource to a jndi service. I am using tomcat 3.2.1, and I don't believe that this functionality is supplied in either Tomcat or Struts.

You could use a Visitor pattern for an application Validator. Each form
would implement a Visitable interface and could be passed to the application
Validator where it (the Validator) would then determine which validation to
use for the form, perform the validation, and return successfully or through
some exception. This way, all validation logic can reside in one location.
The kind of bends some OO concepts (encapsulation), but is a nice way to
decouple the validation logic from each form.

Struts could create an ActionErrors object with an ActionError for each
conversion error.
If an error does get raised at that early stage, then one will no doubt
be raised later on
in the Action. The difference is that the coder has to 
a) check for the conversion error again, 
b) raise an error again.
It also means that checking for such user mistakes is spread across
mulitple layers in the application
and also across multiple components within the system. I think it would
be nice to centralize
such type checking in one part of the system. 


The error message strings could be defined in a similar fashion to
errors.header and errors.footer.
Maybe something like: 
errors.conversion.NumberFormatException=You must enter a number for the
{0} field, not {1}.

Then when Struts comes across a type error, it raises the error then and
there, using a resource
such as the one above to report to the user.

As mentioned earlier in this thread this option could be configurable in
Struts as it may not
always be desirable.

If the validate() method does the type checking then we must implement
type
conversion code and type checking code in every single form bean we
write!
On large systems, this is sometimes very unfun.

Any thoughts?

Actually, Struts will attempt to convert values as it populates a form 
bean. This is done in BeanUtils.populate(), which is called right at the 
end of RequestUtils.populate(). However, the problem is what to do if it 
can't be converted. For example, if I define a form bean property as an 
int, and the request contains "abc", what should Struts do?

In 1.0, it will set the property to a (configurable) default value, but 
that's not a good solution when there's no obvious candidate meaning 
"invalid" (e.g. for a boolean). It also destroys the original user input, 
so when validate() fails and returns the user to the input form, you can no 
longer display to them the mistake they made. (By default, in the situation 
I described above, the user would see "0" where they entered "abc".)

So it's really best if form bean properties are all strings. What you *can* 
do, though, is have your validate() method check that the value can be 
converted to what you want, and return an error if it can't. For example, 
you might use Integer.parseInt() to ensure that a valid integer was entered.

Bob, 
I can see what you mean. The 
RequestUtils.populate(Object bean, String prefix, String suffix, 
HttpServletRequest request)
methods do no type conversions.
So do you call the additional conversion methods during the validate()
method on the ActionForm?

I am very new to struts as is, but as I far as I can tell from reading
the implementation of the above method, 
the ActionForm can only have String properties. Is this correct?

If so, it would be nice if the ActionForm could support types other than
String and the
struts engine would convert these in a similar fashion as Ant does to
the attributes in the xml build file.
An error message could be returned to the user if they entered a String
into an Integer field, say.
This behavour may not be always desired, so it could be switched on and
off in the .
 This may open a can of worms however, Date formats spring to mind.
However, comming from a background of using tags in anger, I wrote a lot
of code
converting Strings to other objects, (mostly Longs, ints, (B)booleans ).

Just my 2 Bobs worth.


cheers, 
Nick

RE: Stupd question about Struts and EJB.

[rhayden]

This is the approach that I am using, but to simplify the design I have
interconnected the view and model. I would like to eliminate this coupling-
so if anyone has some suggestions or could recommend a pattern I could apply
please let me know :) What I am doing is creating entity beans that resemble
the ActionForm as much as possible- for the most part there is a loose 1 to
1 relationship between entity EJB and ActionForm. There are some exceptions,
but this is how 80% of the app is designed. I use session EJBs to manage the
entity EJBs and map these to appropriate ActionForms (using the Struts
copyProperties util). So, the session EJB must be aware of the ActionForm,
since this is the object that it returns. To persist data, the ActionServlet
obtains a reference to the session EJB and would send a save() method I have
implemented the ActionForm which then is copied to an entity EJB. Ideally
there should be a proxy between the EJB tier and the Struts tier, so the
session EJB does not need to be aware of the ActionForm. But, I am not about
to create another intermediate object with the same properties and
setters/getters. Some of my forms have up to 30 properties so this is way
too much work! I think this should be done automatically.

One more thing- the copyProperties requires that properties are the same
type. But, the view is basically just String-based where the ejb tier
consists of real Date, BigDecimal, etc... So what I find myself doing is
creating additional methods in the ActionForm that make this transformation.
For example setCustomerId(BigDecimal) and setCustomerIdStr(String). Then use
the string version for Struts, and when copyProperties is invoked it will
map the BigDecimal value to the EJB. Perhaps I should extend copyProperties
to support basic type conversions- or has this already been done elsewhere?

thoughts or suggestions?

Thanks,
Bob

My understanding is that with struts you should keep your EJBs entirely
independant of
anything to do with struts or servlets. You can and should however have
a standard naming
convention for the getters and setters across the EJB, the ActionForm
and the html form elements.
this allows you to call PropertyUtils.copyProperties(java.lang.Object
dest, java.lang.Object orig)
when you are ready to store the details entered by the user.

Please let me know if this does not sound right.

[Maya Muchnik]

I have the similar case with Beans not implemented "Serializable". I will use
PropertyUtils.copyProperties(destBean, srcBean) to propogate the properties.

RE: Stupd question about Struts and EJB.

[Deadman, Hal]

I use EJBs without using copyProperties although it's a matter of
preference. I have a set of JavaBeans that you could call "Data Beans"
because they are often similar to my Entity Beans and they don't contain any
business logic. They are struts free and I pass these data beans to some EJB
components. I often nest the data bean inside the ActionForm class as a
property and use the Struts nested property functionality to populate the
Data JavaBean directly. Sometimes I don't use a nested JavaBean and I just
pass the individual properties of the form to the EJB component. I like
using nested java beans better than calling copyproperties because if I have
a Databean anyway, I don't want to have to redefine lots of getters and
setters in the Struts form bean.

Re: Stupd question about Struts and EJB.

[Robert Leland]

As far as struts 1.0, the Form bean is used only to redisplay
information to the jsp page. Typically the EJB might be loaded/unloaded in the
action class. If you search www.mail-archives.co,m Craig talked more about this in 
detail.

In future version of struts this may be enhanced.

Re: Stupd question about Struts and EJB.

[Jim Richards]

EJBs come in two flavours (as opposed to flavors), session beans and entity
beans.
Session beans represent business logic and rules, entity beans represent a
row in the database.

The model that you'd use is to have Actions do the basic processing of form
elements into data beans (just regular beans, nothing special), but no business
rules.
The Action then calls a session bean with the data bean to do something 
(eg. usdate user details in the database). The session bean connects to the
database with an entity bean (or more than one depending on the database
structure).

Visually, you'd have

JSP =>  Action  =>  Session Bean=> Entity Bean  => Database

Hope that helps.

Stupd question about Struts and EJB.

[Cameron Ingram0]

I am in the process of convincing my company to go with MVC 
and Struts. As with any thing new, people are sometimes resistant 
to change. One of the opposition questions I am getting is, 
how will this work with EJB(problem is I don't know too much about EJB 
currently).  Do the EJB's references just go in the Form and Action Bean 
and every thing else behaves the same? Are there any obvious points that I can 
bring up on the subject? 
Any help on this subject would be much 
appreciated!
