Re: Interceptors and thread-safety

The "Writing Interceptors" guide pretty clearly states that "Interceptors are shared between requests 
and must be thread-safe."   However, there are some Interceptors--such as execAndWait and roles--which accept 
parameters (e.g. "delay" and "allowedRoles") and which, ostensibly at least--use simple setter 
methods to apply these to instance variables.  So, how can these be thread-safe if new Interceptors aren't being 
instantiated for every request?


Because the parameters don't come from (or vary with) the request. 
Interceptor parameters are passed in once, when the interceptor is 
instantiated. That same instance is then applied to each request for 
which it's configured.

Re: tiles-defs.xml and extended attributes...

2007/4/13, Rod Bollinger <[EMAIL PROTECTED]>:

Is there a way to define these extended attributes in my TLD file or would
this require an extension to the tiles-config_1_3.dtd (not really
preferable)? What is the correct procedure for declaring these "extra"
attributes such that they are considered "valid"?


I think that you should use  instead of , that takes
 elements too.

I'm not sure what you mean by 'getting this to post back to my action'. 
If you are trying to update a property whose type is an enum using a

It depends somewhat on which version of Struts you're talking about. 
Generally, Struts 2 makes testing easier by reducing dependencies 
through well defined abstraction interfaces.


For Struts 1 actions, it's a bit trickier since they generally expect 
certain HTTP Servlet-specific objects to be available. You will 
generally want to keep your actions as simple as possible and move most 
of your application/business logic into POJO service classes to make 
unit testing easier.


You can also use tools such as Cactus and HtmlUnit to help with creating 
integration tests and such. Mock frameworks such as the one Martin 
mentioned can also be a good choice.

GOTCHA, so if I have a common method in all the action and I need to

Ok, another question. If I have an custom interceptor does this sop 
another interceptor from execution. For example, I have this code:

   AccountAction action = (AccountAction)invocation.getAction();
   return action.execute();

shouldn't the interceptor that's responsible for setting the values on

Of course you *could* put all your action code into an

You could put all your action code into filters, then
you wouldn't even need servlets. Or put everything

or worry about whether or not your container
hot-deploys.
  
This will be a great idea. But then I will never be using struts. You

Re: [OT] Re: Preparable or interceptors - is there a better mailing list than this ? some thing for total newbies.

[Mansour]

I have one more question related to this thread.
Let's say I need to write a web app to access and configure a server, 
and these app has to modify the configuration files on this server. How 
would you deal with this ? Write a persistence code so that you can hold 
a reference for each file, or you would let the OS do it's job ?



Dave Newton wrote:

--- Mansour <[EMAIL PROTECTED]> wrote:
  

So I have to get away from OO in order to do this.



Nope.

Nobody is saying you *can't* do it like you are
describing. And it'll work great, until you want to:

(a) Change how your objects are persisted (say,
switching to iBatis, or Spring-based JDBC, etc.)

(b) Test parts of your logic/app/flow without having
to use a real database (for instance, to simulate
failures, operate on arbitrary data, create
pathological use cases, etc.).

  

So, no point in doing things OO ?



Depends. Is it non-OOP to separate concerns? The
representation of my data is not related to how it is
persisted. If how I store my data *does* undergo a
change it's like to be a very large infrastructural
headache.

I would rather change well-defined persistence
interface classes than modify all my POJOs where I
have an additional set of concerns in the code.

I'd argue that compositing objects (POJO, service
impl, whatever) is more OOP than tightly coupling two
(largely) unrelated concerns.

  

I know it pays of,  but do I have to learn and use
many frameworks to get a simple application working?



Nope.

You can do everything by hand: roll your own
persistence layer, do your own type conversion, write
HTML by hand, etc.

To quote from the S1 home page:

{quote}
Is Struts the best choice for every project?

No. If you need to write a very simple application,
with a handful of pages, then you might consider a
"Model 1" solution that uses only server pages.

But, if you are writing a more complicated
application, with dozens of pages, that need to be
maintained over time, then Struts can help. For more
about whether Model 1 or MVC/Model 2 is right for you,
see Understanding JavaServer Pages Model 2
architecture.
{quote}

S2 goes a long way to lowering the entry barrier
(compared to S1) but I don't feel it's the best choice
for simple use cases, particularly if you're not
already familiar with Java's host of supporting
frameworks: there is a steep learning curve to writing
a full-stack Java web-app if you're starting from
ground zero.

Personally I don't recommend it unless you have a
decent non-technical reason ("My boss said I have to
use Java" or "This hot chick said she'd go out with me
if I used Struts 2" etc.) or a decent techical reason
("Everything else we have is in Java" or "I already
know everything about Spring and Hibernate; it would
be quicker" or "All we can deploy on is Tomcat" etc.)

As far as interceptors look at the docs/source code.  If your writing

So here is a scenario for you.  Two users are working on the same

address.  Since you are not re-fetching the data from the database, 
user 1 will not know of the change.  Even if he/she refreshes the page.


I am aware of this. However, I am willing to implement (learn hibernate) 
but for now, and just to get started, I need to write a small 
application (Every person learn in different way). I can not start 
learning many frameworks at the same time, and I would like to focus 
only in struts2. In the future, I'll re-factor my code or modify it to 
suit struts2, and by  then I will learn how to design applications for 
struts2.
  
So far, I am convinced that it's not easier than jsf or .net, and before 
designing a business logic you should keep in mind that it's only to be 
used with Struts2. Unlike other frameworks. May be because this is the 
only MVC2 I am trying to discover.

I 'll keep on trying to get where I want in struts2 and I'll let you know.

After all, thank you. You and Dave were allot of help. I need your 
opinion about this design. Is that the only disadvantage of this design ?

Good point. But wait ! what's wrong with this ? they don't have

Now how do I get a variable from the page and store it in the request

example:

public String intercept(ActionInvocation invocation) throws Exception {
   //I need to get some variable from the page called account 
that holds an object of Account
AccountAction action = 
(AccountAction)invocation.getAction();

  action.setAccount( theAccountFromThePage);

InnoDB is one of the MySQL engines (contrast with

Musachy-
I just created this DB under Oracle

#so I re-configed the pfile (path/initDBNAME.ora) with these params
#MCG change UNDO_MANAGEMENT to AUTO
UNDO_MANAGEMENT = AUTO

#either replace "%AVAILABLE_SID%" with your database name OR hardcode as you 
see here

db_name=%AVAILABLE_SID%

sql>shutdown immediate
sql>startup nomount pfile = "path/initDBNAME.ora"

I noticed at the end of SQL I see ENGINE=InnoDB
Could you indicate what ENGINE=InnoDB is supposed to accomplish???

I'd say  must people don't use that pattern anymore.


I see. So I have to get away from OO in order to do this. I have to create 
a class called services, that has methods like:


populate (Account acc)

and update(Account acc) and ...

That's fine with me. I was a C language programmer before, and familiar 
with 1928 programming style, Where you pass a pointer to a struct  to a 
method and let it do the operation on it. :)

So, no point in doing things OO ?



That was my question. I have to go through all this coding and write all

these extra classes to be able to update info. right ? And I have to
change the bussiness logic (AccountService) to suit this design.




It pays off to have a persistence layer, instead of mixing it up with you
object model. I'm using JPA on top of Toplink and I'm quite happy with 
it,

here is a tutorial, CRUD-like that you might want to take a look at:


I know it pays of,  but do I have to learn and use many frameworks to get 
a simple application working ?

There must be a way to do this with going through all this extra coding 
and framework.

Re: Preparable or interceptors - is there a better mailing list than this ? some thing for total newbies.

[Adam Ruggles]

As far as interceptors look at the docs/source code.  If your writing 
your own interceptor then you can control when it is executed.


So here is a scenario for you.  Two users are working on the same 
account.  User 1 updates the address.  Now user 2 updates the address.  
Since you are not re-fetching the data from the database, user 1 will 
not know of the change.  Even if he/she refreshes the page.

Hummm,
Good point. But wait ! what's wrong with this ? they don't have access 
to each other sessions.  May be store it in the request ?


Now how do I get a variable from the page and store it in the request 
or session through an interceptor.

example:

public String intercept(ActionInvocation invocation) throws Exception {
   //I need to get some variable from the page called account that 
holds an object of Account

AccountAction action = (AccountAction)invocation.getAction();
  action.setAccount( theAccountFromThePage);
  return "beer";
   }


And how do I know if the Interceptor being processed before of after 
the action ?

No, they are not the same.  No, it is not a codename.

The Shale codebase started in a sandbox of the Struts project, and was

Struts committers chose a different path for that (the merger with

If you are attempting to update an account and you

Call the update (or whatever) method on the object.

There's no reason you *can't* do that, but the
architecture overlords will not be pleased.

S2 doesn't care about what else is in the object in
question, as long as it exposes appropriate get/set
methods for the form values you're interested in.

So if you had an object that looked like:

public class Employee {
private String fname; // ...and get/set
private String lname; // ...and get/set
public void save() {
// Does DB stuff...
}
}

you could still use:



in your JSP.

  


That exactly what i did.


Then in your action:

public String execute() throws Exception {
// ...
getEmployee().save();
// ...
}

  


That what I am looking for, but with out the extra fat.

In jsf there's a view, a backing bean, and POJO. However, the backing 
bean holds the POJO and controls it base on user input. In struts2, I 
have to write a persistence code, so that the operations on the POJO can 
be performed in a similar way.  What is the way around writing these 
extra classes which will involve modifying my existing code ?




Again, accountService is another class. So I have to
split the attr form the behavior of each object in 
two classes. right?



You probably *should* but you don't have to.

  
And I have to change the bussiness logic 
(AccountService) to suit this design.



Depends on how you implement AccountService, I guess.

A lot of people using S2 take advantage of Spring and
its support for several persistence paradigms[1].
While I prefer iBatis or Hibernate, JDBC is another
Spring built-in option.

As an example, a Hibernate version of an Employee CRUD
action might consist of (at least) the following:

- An S2 Action: tells application where to go and why.
- An IEmployeeService: wraps up persistence
functionality.
  


This is what I am trying to avoid writing at this point.
I need only action and POJO.


- An Employee object: very simply POJO.

In turn, the IEmployeeService implementation might
contain an IEmployeeDao. Since my most recent project
have been Hibernate-based I use a modified
HibernateTools template to generate the DAO and its
interface.

I'll tell my IEmployeeService impl to save the current
employee:

getEmployeeService().saveOrUpdate(getEmployee());

My Hibernate impl of IEmployeeService.saveOrUpdate()
will look more or less like:

Session session = getSessionFactory().openSession();
Transaction tx = session.beginTransaction();
session.saveOrUpdate(employee);
tx.commit();
session.close();

Your JDBC impl of IEmployeeService.saveOrUpdate()
might look like (pseudo-code):

if (employee.id == null) {
// Build SQL update string.
} else {
// Build SQL insert string.
}

That's what you're currently putting in the Employee
object.

Why don't I think that's a good idea? It tightly
couples your data to how you deal with your data.
Isn't that what OOP is for? In theory, yes. In
practice, it just doesn't work out that well,
particularly in Java.

Now, you could put persistence stuff in your object
via an interface; I'd be less irritated with that, so

Nobody is saying you *can't* do it like you are
describing. And it'll work great, until you want to:

(a) Change how your objects are persisted (say,
switching to iBatis, or Spring-based JDBC, etc.)

(b) Test parts of your logic/app/flow without having
to use a real database (for instance, to simulate
failures, operate on arbitrary data, create
pathological use cases, etc.).

> So, no point in doing things OO ?

Depends. Is it non-OOP to separate concerns? The
representation of my data is not related to how it is
persisted. If how I store my data *does* undergo a
change it's like to be a very large infrastructural
headache.

I would rather change well-defined persistence
interface classes than modify all my POJOs where I
have an additional set of concerns in the code.

I'd argue that compositing objects (POJO, service
impl, whatever) is more OOP than tightly coupling two
(largely) unrelated concerns.

Nope.

You can do everything by hand: roll your own
persistence layer, do your own type conversion, write
HTML by hand, etc.

To quote from the S1 home page:

{quote}
Is Struts the best choice for every project?

No. If you need to write a very simple application,
with a handful of pages, then you might consider a
"Model 1" solution that uses only server pages.

But, if you are writing a more complicated
application, with dozens of pages, that need to be
maintained over time, then Struts can help. For more
about whether Model 1 or MVC/Model 2 is right for you,
see Understanding JavaServer Pages Model 2
architecture.
{quote}

S2 goes a long way to lowering the entry barrier
(compared to S1) but I don't feel it's the best choice
for simple use cases, particularly if you're not
already familiar with Java's host of supporting
frameworks: there is a steep learning curve to writing
a full-stack Java web-app if you're starting from
ground zero.

Personally I don't recommend it unless you have a
decent non-technical reason ("My boss said I have to
use Java" or "This hot chick said she'd go out with me
if I used Struts 2" etc.) or a decent techical reason
("Everything else we have is in Java" or "I already
know everything about Spring and Hibernate; it would
be quicker" or "All we can deploy on is Tomcat" etc.)

I think you asked how to do it, and we are giving you tips based on 
our own

experience, there is a zillion ways of doing what you are asking.

musachy
Great, that 's how I designed the classes for the logic: I have a class 
called Account and it contains all the operations and data that an 
account would need: updateInvoice(somefileds), 
updateAccount(somefileds). The Account data is to be populated the view, 
through AccountAction. Now how do I update (get my hand on the Account) 
that needs to be updated.


One idea was to pass back the account obj to the controller, but if I 
pass it back it has to be a string !!
another idea was to pass back the accID. Ok, then I have to retireve the 
whole account data from the data base, just to update something, which 
not an option.
third idea was to use a persistence objects. Well how many things do I 
have to learn and use to get this small app working. On the other hand, 
I would really like to use OO, meaning encapsulate the behavior in the 
Account Obj.



Next, I am gonna try to find a way to push the Account in the view on 
the stack and access it back from the Action.
Or may be just store it again in the request. Which is not struts for ! 
right? isn't it to hide the access and code with request and session ...


If you have an idea, then let me know.

There's no reason you *can't* do that, but the
architecture overlords will not be pleased.

S2 doesn't care about what else is in the object in
question, as long as it exposes appropriate get/set
methods for the form values you're interested in.

So if you had an object that looked like:

public class Employee {
private String fname; // ...and get/set
private String lname; // ...and get/set
public void save() {
// Does DB stuff...
}
}

you could still use:



in your JSP.

Then in your action:

public String execute() throws Exception {
// ...
getEmployee().save();
// ...
}

You probably *should* but you don't have to.

> And I have to change the bussiness logic 
> (AccountService) to suit this design.

Depends on how you implement AccountService, I guess.

A lot of people using S2 take advantage of Spring and
its support for several persistence paradigms[1].
While I prefer iBatis or Hibernate, JDBC is another
Spring built-in option.

As an example, a Hibernate version of an Employee CRUD
action might consist of (at least) the following:

- An S2 Action: tells application where to go and why.
- An IEmployeeService: wraps up persistence
functionality.
- An Employee object: very simply POJO.

In turn, the IEmployeeService implementation might
contain an IEmployeeDao. Since my most recent project
have been Hibernate-based I use a modified
HibernateTools template to generate the DAO and its
interface.

I'll tell my IEmployeeService impl to save the current
employee:

getEmployeeService().saveOrUpdate(getEmployee());

My Hibernate impl of IEmployeeService.saveOrUpdate()
will look more or less like:

Session session = getSessionFactory().openSession();
Transaction tx = session.beginTransaction();
session.saveOrUpdate(employee);
tx.commit();
session.close();

Your JDBC impl of IEmployeeService.saveOrUpdate()
might look like (pseudo-code):

if (employee.id == null) {
// Build SQL update string.
} else {
// Build SQL insert string.
}

That's what you're currently putting in the Employee
object.

Why don't I think that's a good idea? It tightly
couples your data to how you deal with your data.
Isn't that what OOP is for? In theory, yes. In
practice, it just doesn't work out that well,
particularly in Java.

Now, you could put persistence stuff in your object
via an interface; I'd be less irritated with that, so
Employee would have an IEmployeeService in it, which
could then be called (internally) by Employee. Meh.

Again, for simple use-cases, I don't think it matters.
Java architect cowboys get all bent-out-of-shape when
they see code like that, but... let's face it, if it's

validwhen not working

[Glenn Wilson]

Hi all, new to using validator. I have validator working on most of my 
applicaiton but having a problem doing a "validwhen". I've been using the 
examples in the "Jakarta Struts Cookbook".


Here is my question(s):

I've noticed that javascript code is generated unique to the form name. 
However, when I setup a "validwhen" for  the form no form specific 
javascript code gets generated. If I include "date" in the "depends" 
attribute I do get javascript code to do the date validation but nothing to 
deal with the validwhen?


So in my example, I have a page called Spiffs. The form name is SpiffsForm 
and I've included the  
tag in the page. I have two date/text fields (startDate,endDate) which are 
optional however, when one is populated the other date field needs to be 
populated.


The validation.xml file reads




 
 test
 ((spiffFilter.endDateAsString == null) or (*this* != 
null))

 



 
 test
 ((spiffFilter.startDateAsString == null) or (*this* != 
null))

 



I'm using Struts 1.3.5 with validator 1.3.0 on a Tomcat 5.5 instance.

Any help would be appreciated.

Struts 2.0.6 != Shale?

I always though Shale was a codename for the new Struts 2.0. However, I 
am a little bit confused now that I've seen that there a two different 
websites:


1) http://struts.apache.org/2.0.6/
2) http://shale.apache.org/


I also see two download section for both, Struts 2 and Shale:

1) http://struts.apache.org/download.cgi#struts206
2) http://apache.rmplc.co.uk/shale/


I did a lot of reading, and I concluded that Struts 2 must be different 
from Shale, since Struts2 is based on WebWork2 and Shale is using a JSF 
approach.


So, question: Are these the same frameworks? Is Shale a codename for 
Struts 2?

S2 will create an Account object and populate the
Account with the form values. Whether or not you're
updating or creating an Account, as Adam said, is
determined by whether or not the account ID is set.

Much of this is discussed in the CRUD tutorial:

http://struts.apache.org/2.x/docs/crud-demo-i.html

Looking at it now I can see there are some things that
should be updated, but just reading it without
implementing it might still be helpful. The showcase
app is also a decent place to look for some types of
information.

Struts testing

[puchacz]

Hi

I would like to ask if You (as Struts programmers) see some + or - of
testing Struts? I know JSF where I can test  all components as a standalone
