I don't see any advantage on creating Actions with Spring. It works fine
without it and it seems unnecessary configuration. Perhaps someone else can
point out clear advantages of this.

I would suggest using wildcards to reduce the configuration of your actions,
and also giving your actions a better name for when you have more than one
domain class (otherwise you don't know if list is related to Person or to
Address). For example:
package name=persons namespace=/persons extends=struts-default
action name=*-* class={1}Action method={2}
result name=success/WEB-INF/pages/{1]/{2}.jsp/result
/action
/package
This example would allow any action named Something-someaction to be mapped
to method someaction of class SomethingAction and have a result of
pages/Something/someaction

Re: Struts2 + Spring/Hibernate
Hi,
I've just created similar skeleton couple of days ago.
To let Spring generate your Service and DAO beans, you have to specify also
the GenericService and GenericDAO in your applicationContext xml. You (can)
set them as abstract and you have to specify the inheritance relationship
between the PersonDAO and GenericDAO, the same for Service of course.
At least this worked for me...
Regarding your design... I thought that DAO design pattern is here to handle
access to data objects, i.e. CRUD. So I don't see the benefit of the Service
here? Can someone explain this? In my application I don't have any business
logic but CRUD. Is the Service layer needed here or can DAO act as the
Service as well?
And finally I've got one more question, which I believe is related to
this... One thing everyone suggest is to use wildcards in the Struts2
web.xml for CRUD operations. But this reference to many action classes with
the same functionality. My question is, if we remove the duplicity in
web.xml, can't we remove the duplicity in the Java code as well? Can't we
create generic CRUD action as well? (Similar to generic DAO or generic
Service).
Thanks,
Jozef

I am in the process of implementing Struts2 along with integrated
support with Spring and Hibernate. While I have found various examples
on the web, I tend to find they vary. My application will primarily
focus about 75% of the time on data queries and displaying this data to
end users while a smaller 25% will actually support a full CRUD based
system for certain data records.
So far the examples I have seen have focused on implementing a class
structure similar to the following:
com.company.app.hibernate.dao.PersonDAO.java
com.company.app.hibernate.dao.GenericDAO.java
com.company.app.hibernate.model.Person.java
com.company.app.hibernate.service.PersonService.java
com.company.app.hibernate.service.GenericService.java
com.company.app.struts2.actions.PersonAction.java
The GenericDAO class is a template-like class that holds a reference to
the EntityManager along with methods for saving, deleting, and
retreiving objects persisted inside the EntityManager. The PersonDAO
object extends GenericDAO and provides an additional list method shown
below:
public class PersonDAO extends GenericDAOPerson,Integer {
public ListPerson list(int page, int size) {
Query query = this.em.createQuery(from Person order by lastName,
firstName);
query.setFirstResult((page-1) * size);
query.setMaxResults(size);
return query.getResultList();
}
}
The Person class itself is annotated as an @Entity object with a unique
property that is marked as the entity's unique ID and all the properties
of the Person table along with get/set methods for each property.
GenericService is another template-like interface class that defines
create/delete/update/getById/list methods. Then PersonService
implements this GenericService interface with calls to the PersonDAO
object for each of these methods.
And lastly PersonAction extends ActionSupport and implements
StrutsStatics where it gets constructed with the GenericServicePerson
class.
Inside my web\WEB-INF\myAppContext.xml file I have:
!-- daos --
bean id=personDao class=com.company.app.hibernate.dao.PersonDAO/
!-- services --
bean id=personService
class=com.company.app.hibernate.service.PersonService
property name=dao ref=personDao/
/bean
!-- actions --
bean id=personAction scope=prototype
class=com.company.app.struts2.actions.PersonAction
constructor-arg ref=personService/
/bean
Is there anything else I should include in myAppContext.xml?
Any special inclusions or statements I need in my
applicationContext.xml?
Per one example I saw, struts.xml should be as follows:
package name=persons namespace=/persons extends=struts-default
action name=list class=personAction method=list
result name=success/WEB-INF/pages/persons/list.jsp/result
/action
/package
Thus far this example seemed easy to understand, particularly because
we're only dealing with a single table. Before I go into how to take
this example and build from it, do any of you have any input or
suggestions on the approach I am taking with objects? Any lessons
learned?
Thanks

How to get Login page while submitting a data form
Hi All, My requirement is this: 1. User fills a form and submits. 2. If he has not logged in, login form comes up. 3. after logging in, the data automatically gets submitted and next page comes. I am new to struts and unable to figure out the natural solution, even after a lot of googling. As I understand step 2 should be easy using interceptor, but how to get step 3 work? I am using struts 2.1.8. thanks, Sanjay http://www.sanjaypatel.name _ New Windows 7: Find the right PC for you. Learn more. http://windows.microsoft.com/shop
RE: Struts2 + Spring/Hibernate
Hi Wild Oscar, thanks for your input.
First, I agree my design needs work with respect to naming conventions and
thank you for the suggestions. This was more of a very crude example of how I
should be relating components in the Hibernate/Spring/Struts2 design pattern so
I can grasp the concept. In my Struts1.2 days, we didn't leverage spring nor
hibernate and wrote our own DAO object framework. While it worked nicely,
Hibernate has far more benefits.
Now taking the example deeper, lets assume that Person is also related to two
other tables in my database. For example, one table that stores Payroll and
another that stores MenuPermissions. I would need to create two additional
Entity objects, create their DAO and Service layers and then in all three
entity objects, I would need to annotate the relationship amongst the 3 tables,
correct?
When I finally get to the point where this framework will hit the road is when
I will have 4 or 5 tables in a database, all with relevant information about a
key record or set of records in the main table and I will need to join all
these records together. In the past we typically created a single record
object for each query we had and while that worked nicely, there were lots of
duplicity that I aim to avoid.
Is this the right path and expectation for hibernate/spring/struts when I have
a join between multiple database tables?
Chris

Re: How to get Login page while submitting a data form
Hi Sanjay, when intercepting action for the first time (no logged user), You can save submited data along with request uri and put it into session/database then after login (inside login action), check if these informations are present in sesion/database and forward to desired action with all the params that You have collected before login.

Validation and conversion conflict - best method?
I have an object with a java.util.Date field. I present the object inside a
form with the following tag:
s:textfield key=detail.date
value=%{getText('detail.date',{schedule.dateTime})} label=Date/Time/
where detail.date is a date formatting pattern.
The problem arises because after getText(), the field is populated with a
String. When the String is submitted, I get an error because I don't have a
setDateTime(String) method.
I've written a data type conversion routine and applied it to the field, and
it works fine as long as the user enters a date string in a valid format. If
an invalid string is entered, the type conversion fails and a null is
returned - so the user doesn't see the original date string, or even the
incorrect one they entered - they see 'null'.
So, I tried to add validation (using a validation xml file). However, it
seems that the conversion is done regardless of whether or not the
validation fails, so I end up with the same results.
Next, I tried to implement the validation using the validate() method in the
class, but I'm having similar troubles - I need to use the converter to
convert the String to a Date - and I end up with all the previously
described problems. If I don't use a converter, the field is null when it
gets to the validate() method.
It isn't practical for me to change the class that contains the Date field
to add a setDateTime(String) method. It seems like a hack to use a variable
outside of the class to hold the Date in String form and then worry about
keeping it in sync with the actual object.
I can't be the first to struggle with this, so I'd be interested in hearing
how some of you have solved this in the past - is there a clean and elegant
solution?
Thanks in advance!

Re: Validation and conversion conflict - best method?
One quick solution might be , which I am using but most of them may not agree
with me,
-- Delcare a string in the action which take the value enter in the text
box.
-- Add the validation in the validation.xml as a regular expression and can
add as requiredString , if the filed is mandatory to enter.
-- The regular expression will check the format of the date.
-- once validation passes can convert the string to date throught the util.
Its an alternate solution.

I created new space to work on the documentation, the guide main page is here: http://cwiki.apache.org/confluence/display/S2NewDocDraft/Guides I think it is very important that we clean up the documentation, document missing parts, remove outdated stuff, the version boxes, and the snippets as well. I will reuse content from the current documentation and add new entries.

RE: html:link submit with request parameters
Use javascript to get a reference to the form, and call its submit
method.
EG
form name=form id=form action=/setup.do
input name=blah /
input type=submit/
/form
script
function submit() {
document.getElementById(form).submit() return false;
}
/script
a href=javascript:submit();
onclick=return submit();click me/a

Subject: html:link submit with request parameters
I need to submit the form when the html:link . is
clicked/pressed and also need to pass parameters.
c:url value=/setup.do var=setupUrl
c:param name=empId value=${custItr.empId}/
/c:url
html:link href=%=
(String)pageContext.getAttribute(\setupUrl\) %
transaction=true
c:out value=${custItr.empName}/
/html:link
but this is not submitting the form. How can I submit the
form and also pass the request params? Basically I want other
values entered in the html form are set to the form bean so i
can acess those in action class when the link is pressed.
How can this be done?
Thanks.

RE: How to get Login page while submitting a data form
Hi Pawel, Thanks for the insight. I would give a try. Being a common scenario, is there any existing work already present for this, so that I don't have to reinvent the wheel? I guess there should already be some established library / code sample which people follow. What do people normally do? when intercepting action for the first time (no logged user), You can save submited data along with request uri and put it into session/database then after login (inside login action), check if these informations are present in sesion/database and forward to desired action with all the params that You have collected before login. My requirement is this: 1. User fills a form and submits. 2. If he has not logged in, login form comes up. 3. after logging in, the data automatically gets submitted and next page comes. I am new to struts and unable to figure out the natural solution, even after a lot of googling. As I understand step 2 should be easy using interceptor, but how to get step 3 work?

Re: Validation and conversion conflict - best method?
Hi Ben,
I think I understand your problem. I am have a similar situation where
I have a person class with a birthday.
I ended up writing a Converter to handle the date (because I needed it
in the format dd/mm/). I used the Person-conversion.properties to
say that I want that converter applied to that field. And for the
validation I have something like the following in the
Person-validation.xml file.
field name=birthday
field-validator type=conversion
message${getText(persona.birthday)} :
${getText(validation.invalid)}/message
/field-validator
/field
So my converter handles the case where there is no date. I don't have
to use the getText method. I just refer to the property as I would
with a normal field.
Then my converter throws a conversion exception if there are problems
converting the date. I then catch this with the above line in my
validation.xml.
I am new to the Struts 2 world but I think this is a relatively clean
solution. Happy to hear if anyone else has a better way.
Cheers, Carl.
Quoting ben_979 benninesevenn...@yahoo.ca:
I have an object with a java.util.Date field. I present the object inside a
form with the following tag:
s:textfield key=detail.date
value=%{getText('detail.date',{schedule.dateTime})} label=Date/Time/
where detail.date is a date formatting pattern.
The problem arises because after getText(), the field is populated with a
String. When the String is submitted, I get an error because I don't have a
setDateTime(String) method.
I've written a data type conversion routine and applied it to the field, and
it works fine as long as the user enters a date string in a valid format. If
an invalid string is entered, the type conversion fails and a null is
returned - so the user doesn't see the original date string, or even the
incorrect one they entered - they see 'null'.
So, I tried to add validation (using a validation xml file). However, it
seems that the conversion is done regardless of whether or not the
validation fails, so I end up with the same results.
Next, I tried to implement the validation using the validate() method in the
class, but I'm having similar troubles - I need to use the converter to
convert the String to a Date - and I end up with all the previously
described problems. If I don't use a converter, the field is null when it
gets to the validate() method.
It isn't practical for me to change the class that contains the Date field
to add a setDateTime(String) method. It seems like a hack to use a variable
outside of the class to hold the Date in String form and then worry about
keeping it in sync with the actual object.
I can't be the first to struggle with this, so I'd be interested in hearing
how some of you have solved this in the past - is there a clean and elegant
solution?
Thanks in advance!

RE: How to get Login page while submitting a data form
If a form requires authentication, don't render it until the user is logged in. If you are worried about the user's session timing out before the form is submitted, implement some sort of javascript timer that (after a period equal to a session timeout), pops up a modal login form. Successfully submitting the login form Resets the timer, makes the login form disappear, and the user is free to submit their form. -Original Message- From: Sanjaya Kumar Patel [mailto:skpate...@hotmail.com] Sent: Friday, November 13, 2009 3:48 PM To: Struts User Group Subject: RE: How to get Login page while submitting a data form Hi Pawel, Thanks for the insight.

Re: Validation and conversion conflict - best method?
I have a related question, but it's a bit of a side-track as I try to solve my original problem. What is the naming convention and the difference between the two types of -validation.xml file naming? I think I understand that ActionClass-validation.xml is called for all (non-excluded) methods in the Action. The documentation on the other method is very scarce and difficult to understand. It suggests that the name should be ActionClass-ActionAlias-validation.xml, however it isn't really clear what ActionAlias really means. In my case, my action class is called ScheduleDetail. The form that invokes the update is coded as follows : s:form action=ScheduleDetail_update So, my understanding is that if I want validation ONLY for this method, the naming convention should be: ScheduleDetail-ScheduleDetail_update-validation.xml Is this correct? I've tried ScheduleDetail-validation.xml just to use the basic naming definition, but it doesn't seem to get invoked. The messages that I have defined in the file are never presented, I am seeing what I think are generic struts error messages for type conversion errors (I'm trying to force failure by entering a string in an int field). -- View this message in context: http://old.nabble.com/Validation-and-conversion-conflict---best-method--tp26341189p26345292.html Sent from the Struts - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
Struts Dojo Question
Hello all.
In working through some Dojo stuff, I have come to a roadblock, on which I
hope someone will be able to shed some light.
I have a page that displays a user's account info. If they press update,
Dojo pops up a dialog box which allows them to update their info. Opening a
Dialog box in a web browser is very cool, and it's easy to do with Dojo.
In the dialog, there is are three dropdown boxes, named Continent,
Country, and Locality. If the user chooses the continent of North
America, the Country box should show only the countries for North
America. If the user chooses Western Europe, the Country box should
show only the countries for Western Europe. And so on; you get the idea.
I am using the standard Json ItemFileReadStore attached to my Postgres
database. The Continent: field gets filled properly. But when I select a
different Continent, and the call is made to the Action class to retrieve
the list of countries for the new continent, the new continent's
abbreviation is never passed in.
My javascript reads like so:
var selectedContinent ;
function continentWasChanged()
{selectedContinent = dijit.byId('continent').attr('value') ;
console.log ('found selectedContinent as ' + selectedContinent) ;
theStore.fetch(selectedContinent) ;
}
The console.log statement shows that selectedContinent DOES have the value
I expect.
The intention is to have the selectedContinent passed into my action class.
My struts.xml snippet reads like so:
action name=countryData method=countryData
class=LocationAction
result name=NONE/result
param name=continent#attr.selectedContinent/param
/action
In my LocationAction class, I have a setContinent(String) method, and the
passed parameter is the string #attr.selectedContinent, not NA when
North America is selected.
In going through the OGNL docs, I thought that #attr is the way of
selecting data on a page, but maybe not in this case, because the
LocationAction class is only used to serve up locations. The jsp is really
bound to the UserDisplayAction class. I'm thinking if I move the Action
logic into the UserDisplayAction class, it might work better, but I hope I
can separate the logic in this fashion.
I guess the question is whether it is possible to do what I am trying to do
here, or not?
Thanks,
Tom

Hibernate/Spring
I have done a fair amount of reading today on the topic again and
developed a few simple classes to support my service, model, and dao
architecture for using Hibernate 3.3.2 and Spring 2 with Struts2. The
problem I am currently facing is I get a detached error when deleting
an object and I get a null pointer exception in SessionImpl.java when
I try to locate an object by its id.
/* GenericDAO.java */
public T findById(Object id) {
return(getEntityManager().find(clazz, id));
}
public void delete(T entity) {
getEntityManager().remove(entity);
}
Some posts I have seen say for the delete, you should use
getReference() or merge() in order to get an association to the entity
before you call the remove() method. I attempted to use the same type
of logic with getReference() during the findById() and it failed.
Am I missing something in my configuration with Hibernate/Spring with
respect to the session factory or something that I need to revisit?
It really seems as though I may have a missing component or a poor
configuration somewhere.
