Re: referencing javascript files from (action) jsp file
Hi Li,
JSTL and EL give you access to the implicit pageContext object.
From there you can access attributes from request and session.
For example:
c:set var=contextPath value=${pageContext.request.contextPath}/
And then use contextPath variable however you wish.
I'm not sure how this would translate into an OGNL expression.
But I'm sure others on this list do :)

Subject: Re: referencing javascript files from (action) jsp file
Hi Robert and Dave:
I tried c:url in my application, and it works for almost all the case.
But there is one exception:
In my application, i customized the CSS files shiped with Struts JQuery
plugin
and put them under path [{contextPath}/res/struts/].
In JSP, i need add code likes:
sj:head jquerytheme=redmond scriptPath=%{contextPath}/res/struts/ /
to tell Struts JQuery plugin where to load js/css files.
In this case, i think c:url can not help,
because [contextPath] is a part of attribute value of another tag.
I tried %{#request.getContextPath()}, but it don't work for some
reason i don't know.
So i decide to remain my old solution(adding a property in my Action),
so i can reference [contextPath] in Struts tags.
Of cause, in simlpe URL case, c:url is a better choice.

I suggest you to reference your resource file(js, image, css and so
on) in this way:
script type=text/javascript src=s:property value=contextPath
//path/filename.js/script
The [s:property value=contextPath /] part will
render the contextPath where the web application
is deployed.
The [contextPath] is a property defined in Action:
public String getContextPath() {
return ServletActionContext.getServletContext().getContextPath();
}
I put this property in the supper class of all of the Action classes
so i can reference this property in all the pages

Re: additional onsubmit javascript validation
Hi Mead,
Binding validation to the click event on the submit button is not what i
want.
This would fire my validation before the onsubmit validation occurs.
I want to leverage the Struts2 javascript validation framework which already
exists.
Then, if that succeeds, I would like to fire additional javascript
validation.
The Struts2 validation framework dynamically generates the appropriate
validation for
the form if the form has validate=true. Otherwise it doesn't generate it.
However, when
validate=true, it appends return validateForm_MyAction(); as an onsubmit
handler to any existing onsubmit attribute value.
With regards to your second suggestion removing the onsubmit event. I
cannot do this (without modifying code/template)
because if validate=true in the form, it will automatically populate the
form onsubmit attribute.
If I set validate=false, then the Struts2 validation framework doesn't
auto-generate the form javascript validation.

Hi Robert,
Do you have another submit button? such as s:submit/,
Try to bind a event listener to this button, that when you click this
button, you do some validation();
Another way is using the js to remove the onsubmit event, then binding
another method you write, and invoke the myValidation() in that method;
bind
AnoterMethod(){
if(!validateForm_MyAction()){return;}
//Here do your validation
return myValidation()
}

Re: additional onsubmit javascript validation
Hi Dave, Based on my requirements (leverage the existing Struts2 client-side validation framework), I'm not sure modifying the templates will work here. It appears that when validate=true I need a way to tell Struts2 validation framework to not populate the onsubmit attribute. But I still want it to generate the appropriate javascript based on the field validations I have defined for the action. This way I could use my own onsubmit handler to call the auto-generated javascript method (validatForm_MyAction()) at the appropriate time. Reviewing the existing template files didn't reveal that this was possible by overriding a template.

Re: Struts2 Dynamic Merge of two webform objects / join two objects in database
Hi Nicolas, I'ld also be interested in hearing about an elegant solution to this problem as well. Ideally it would be nice if we all had nice simple models where we could reuse our hibernate objects for both persistence and web binding. However, if have found, this is often not the case. Although maybe not ideal, for the case you mentioned, i have always ended up creating/using a separate DTO (data transfer object) which contained a subset of the Hibernate entity object properties. If the properties are simple enough, I have been able to use BeanUtils.copyProperties() to transfer the appropriate values between the two objects. Probably not the answer you were looking for, but this has been my approach so far. /robert - Original Message - From: Nicolas Kopp nicolas.k...@empirica.com To: user@struts.apache.org Sent: Friday, September 03, 2010 5:23 AM Subject: Struts2 Dynamic Merge of two webform objects / join two objects in database Hi there, We (Team of two developers) use Hibernate integrated in a Struts2 web application. If we want to perform an update to our objects on the database we fetch the data and load the resulting object into a web form where the user can edit the data. In this web form not all the object's attributes are displayed and editable. Submitting the form data will create a new object with the values set in the web form, which is then saved to the database again using Hibernate. Since not all the attributes from this certain object were set in the web form, some values result as null, which leads us to the problem that these values (even though there are set in the DB) get overwritten with null values. Hibernate is set to dynamic-update=true in all involved mappings. There are (at least) three workarounds that we could think of: 1.Adding the missing attributes as hidden fields in the web form (not very flexible) 2.Adding the missing attributes in the Java code before saving the object to the DB (not very flexible either) 3.Writing a utility class which merges the data from the persistent object with the one created by the web form (flexible but cumbersome). What we do right now is to iterate through all methods of the specific object, find out the getterMethods and setterMethods of both the old database-object and the new Hibernate object, compare values and take the values which are not null. This is not a very satisfying resolution, because some objects contain Other objects with values and so on, sometimes three or more layers of depth. Also, using reflection in Java is not a very nice resolution. We are sure there must be other people out there facing similar problems but even after quite some research efforts we were not be able to find anything of help in the web. We are even not sure if this is more a Hibernate or a Struts2 problem. We'd be really grateful if someone could point us in the right direction. Thanks in advance!

Re: struts2+hibernate+spring - lazyInitaializationException
Hi Greg, I believe Brian is correct. You need to wrap BookDao.find(...) within a transaction or use OpenSessionInView. Either one of these should keep the session open when you are navigating the object graph in your DAO. If you use OSIV (OpenSessionInView) filter, then you can navigate the object graph in your web tier as well. We are using both OpenSessionInView filter and a service layer which acts as a facade to the data layer (DAOs). The services are annotated with @Transactional (although for readOnly transactions this is really unnecessary within the OSIV scope; but they are there for consistency). /robert - Original Message - From: Brian Thompson elephant...@gmail.com To: Struts Users Mailing List user@struts.apache.org; lukasz.len...@gmail.com Sent: Monday, July 19, 2010 1:22 PM Subject: Re: struts2+hibernate+spring - lazyInitaializationException Looks to me like the session is being closed in the scope of hibernateTemplate.get().

Re: Session error while loading an object
Greetings, I think that you might want to separate your functional concerns into different objects. One common pattern in multi-level architectures is to have a model object like Customer which would contain domain information for the Customer and a Service object like CustomerService which would be a singleton (many times injected using some IoC container). CustomerService would be used as a fascade to retrieve and persist Customer objects (or rather would delegate to a DAO layer to do the actual retrieval and persistence). The DataSource is usually injected into the DAO layer using your IoC container. Spring is a popular IoC container which is used to manage the middle tier (and web tier if you like). By separating the layers, you could persist Customer to the session and collaborate with the CustomService object and MessageResources when necessary in the web tier and avoid the NotSerializableExceptions you are running into with the DataSource and MessageSources. These are often interfaces whose implementations are provided by some framework, so it's unlikely you will be able to easily make them Serializable (they probably weren't meant to be anyways). Keep in mind, there are many ways to implement multilevel architecture. You may want to do some research on best practices. Spring and Rod Johnson are good resources. You could also reference Martin Fowler. Good luck. /robert - Original Message - From: abhishek jain abhishek.netj...@gmail.com To: Struts Users Mailing List user@struts.apache.org Sent: Wednesday, July 14, 2010 5:15 AM Subject: Re: Session error while loading an object 2010/7/14 Paweł Wielgus poulw...@gmail.com Hi all, You get this error every time when tomcat tries to save someone's session and object of class com.cart.Customer is in it.

Currently I'm using the struts2-spring-plugin-2.1.8.1.jar spring-security-x-3.0.2.RELEASE.jars org.springframework.x-3.0.1.RELEASE-A.jars This seems to work for me for integrating Spring Security(3.x) with Struts2 using Spring 3.x core files. /robert - Original Message - From: Burton Rhodes burtonrho...@gmail.com To: Struts Users Mailing List user@struts.apache.org; Robert Taylor rtay...@dtgresults.com Sent: Monday, May 24, 2010 3:22 PM Subject: Re: Struts 2 and Spring 3??

I want to add Spring Security instead of my home-grown methods, but would really like to use Spring Sec 3.0.4. In order to use Spring Sec 3, I need to use Spring 3.x (Core) as well.

Re: Struts2 annotations and superclass
Ok...i think I found the solution. The super class can provide annotations at the method level for multiple subclasses using the @Actions. If a subclass needs to add or diverge from common functionality provided by superclass method, they can override the method, however, the subclasses method will have to provide the annotation since annotations are not inherited. /robert - Original Message - From: Robert Taylor rtay...@dtgresults.com To: Struts Users Mailing List user@struts.apache.org Sent: Wednesday, April 21, 2010 8:44 AM Subject: Struts2 annotations and superclass Greetings, We are converting from using Struts1 and XDoclet to Struts2 and Struts2 annotations. We have a base action class which handles requests which displays grid style information.

Re: struts 2, how to trigger interceptor after action's execute() ?
To trigger code before an Action is executed place it before the
invocation.invoke().
To trigger code after an Action is executed place it after the
invocation.invoke();
For example:
public String intercept(ActionInvocation invocation) throws Exception {
MyAction action = (MyAction)invocation.getAction();
// doBeforeActionExecuted(); String result =
invocation.invoke(); // doAfterActionExecuted(); return result;

I would like to use Axis2 for remoting and would like to secure these web services using BASIC authentication over HTTPS. I had an identical situation. I wound up using IBM's WS engine built into Websphere, since we are a Websphere shop... interestingly, this is just a version of Axis anyway! They deal with this issue though. Before I did that though, I had a proof-of-concept using a filter to the basic auth check, simulate basic auth in reality. The difference is that instead of request-challenge-validate as the cycle, the incoming WS request is required to container ID/PW with it, so I skip directly to the validate step. This has to be a common problem and was wondering if anyone had cracked this nut yet? I've found examples of doing one or the other, but NOT BOTH at the same time on the same web application. I too would like to know how others have solved this problem. It's nice when the app server has the capability built-in as Websphere does, but I'm interested in how it can be done in the absence of that. /robert Frank - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Validation and error messages in session
Greetings, I'm using Struts 1.2.7 and noticed that functionality has been added to the Action class to store error messages in the session and subsequently be removed after they have been rendered. This is quite helpful in some circumstances. I also know that error messages can be placed in the session or request scope when using the Exception handling framework. Again, this is quite helpful in some circumstances. Are there plans to add this to the Validation framework as well such that we can declaratively identify the scope in which to place the validation messages. I know that upon a validation error that the default RequestProcessor forwards to a configured url and that since the request is forwarded, then there is no need to store them in the session. I recently came upon a case where I have a page with conditionally imported page fragments. The page fragment contained an iframe with some dynamic text input fields. Upon a validation error in the iframe, it forwarded the request to its parent which subsequently rendered the page which subsequently and conditionally imported the page which was supposed to contain the validation error message. Since the import (c:import) was considered a separate request, the validation error messages was lost. I ended up subclassing the ActionMapping class, adding a validationMessageScope property. I also subclassed the RequestProcessor processValidate() and added logic to look for the subclassed ActionMapping class; if found to look up the scope into which to place the validation error messages. If the property had not been set, defaulted to the request scope. So when ever I need to propogate the validation error message across requests, I just add a set-property property=validationMessageScope value=session/ and the error messages is placed in the session. Struts takes care of removing the error messages from the session after they have been rendered. I know this is a special case. The only reason I ask is that Struts already supports the concept of storing the messages in the session and the current Exception Handling framework supports this concept. It didn't seem like too much of a stretch, to allow the Validation framework to support it. Just a thought. /robert - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Using JSTL to access form bean properties
Your form bean should be in either request or session scope under the
name used to define it in struts-config.xml file. What I usually do is
something like the following:
c:set var=form value=${myform}/
and then you can use it like any other object with c:if or c:choose.
c:choose
c:when test=${form.someBooleanProperty}
/c:when
c:otherwise
/c:otherwise
/c:choose
Even though the form bean is already defined in some scope, I redefine
it at the top of the page to avoid having to make multiple reference
changes if my form name happens to change. If it does, I only change it
in one place.

Once the user logs in he/she would be authenticated with the user name, password through Tomcat as it was configured with the database information, table name, etc. I would like to do pretty much the same with Struts. I have checked the O'Reilly Struts Cookbook but, although it has great authentication tips, it does not include a recipe to have authentication with a database. Is there any article on how to perform it with Struts? Any books that you would suggest? So what I think is that I should have a model class to do this kind of authentication rather than using the XML config files. However how would I include all the roles in that class? Have a data structure like a list maybe? That way I could always check for a specific role for every JSP or action whether the user would be allowed or not. Any thoughts? You can set up container managed security in just the same was as you've done previously, you don't need to do anything new or different with Struts (provided container managed security gives you everything you need). Once you have it setup you can tell Struts to restrict access to actions based on roles through struts-config.xml.

datePatternStrict for MM/dd/yyyy seems to allow 04/04/200w
Greetings, I'm using Struts 1.2.7 and trying to validate a date field using the datePatternStrict with a date format of MM/dd/. Everything seems to work as expected until I enter a date like 04/04/200w. It seems that the date validation routine thinks that this is a valid date...or atleast it allows validation of the date field to pass. The docs say that date validation leverages SimpleDateFormat so I looked at the javadocs, but found nothing to indicate that parsing 04/04/200w should pass (although I haven't tested it explicitely with just SimpleDateFormat). I'm using the following snippet in my validation.xml file: varvar-namedatePatternStrict/var-namevar-valueMM/dd//var-value/var BTW, the javascript for date validation seems to catch this, but the server side validation does not. I must be doing something wrong or this must be a known issue. Any ideas? /robert - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Hi,
Can anyone let me know how to automatically check checkboxes?
Below is my current code:

[OT] ORM vs JDBC [WAS- BRANCH: Typical Struts development team and distribution of tasks?]
I've been lurking on this thread for a while and had some observations and questions. Observations: It seems like for most OLAP applications; those applications where the majority of the requirements are real-time read operations (reporting, searching, number crunching, etc... where data cannot necessarily be cached) may be best suited for a JDBC type solution as opposed to using an ORM solution. I think this is because an optimized query or stored procedure can retrieve data faster than drilling into an object graph and its respective relationships (n+1 problem). It seems like for most OLTP applications; those applications where the majority of the requirements are write operations (CRUD) are best suited for an ORM solution. This is because the SQL required for executing these operations is easily extrapolated from meta data and therefore eliminates the mundane task of having to write and maintain. Question: For those applications which are both OLAP and OLTP, then why not use both types of solutions? For example, let's say I have a master-detail type report which does a lot of number crunching and is very complex which returns rows where each row represents a record detail. Clicking on a row is a simple query returning the contents of that row to a detail page. For the report query, I may use a stored procedure or an optimized query. When I click on a row, I leverage my ORM solution retrieving the details with a primary key. It seems like this would solve both problems: 1. Use ORM to handle the simple CRUD operations. Reduce the amount of SQL which has to be hand written and maintained. 2. Use straight JDBC to handle complex/optimized data retrievals. Is this not a reasonable solution? Am I missing something? /robert Larry Meadors wrote: We eliminated lazy loading (it was creating literally thousands of queries), and replaced it with a single stored procedure that we mapped to objects with a RowHandler.

You mean changing the app from using Hibernate to iBatis changed the performance from 10 min to under 1 and so on? Is that correct? Why do you think there was SUCH a drastic change???

Re: [OT] ORM vs JDBC vs OODBMS (was [OT] ORM vs JDBC)
This solution has been discussed, but for now the expectation is real-time data. BTW, thanks for your input on this, but I don't want to hijack this thread for my own particular production issues. I wanted to propose that both ORM (Hibernate, JDO, iBatis) and straight JDBC can/should be used together when one may be better than the other, instead of trying to fit a square peg into a round hole. Don't get me wrong, I would love to use ORM all the time, but sometimes I don't think its appropriate. /robert Leon Rosenberg wrote: Moving the implementation is out of my hands.

I think both solutions have merit and I think that many try to make one solution work for both OLAP and OLTP. Ok, in this case, how about splitting the databases? Keeping OLTP part as is, and creating the OLAP part on daily (hourly or whatever) import basis as a separate DB, where you can create fast indexes, which you can't afford in the OLTP part. Or do you always need to analyse the data instantly? We once made it for a project, where the customer wanted to create new queries for statistical purposes from scratch. Like, today i'd like to know, whether the 50.000 users registered in last month were more female of male, and how many of male users came from north dakota... We created a table, which was imported every night, and contained all the information about a user, which was available in different parts of the system. So the customer was able to analyse everything, without running queries against the live-system.

Re: Struts Approach
Tim, I think things look pretty good so far. Right now Customer is a domain object representing a customer. CustomerDAO is a DAO respsonible for mapping the Customer to its relational counterpart(s). CustomerService collaborates with CustomerDAO to manage the persistence and data access of a Customer. Together these 3 classes make up what I would refer to as a CustomerComponent. This simple component can be used in any of your applications that interact with a customer and need simple Customer CRUD (create, retrieve, update, and delete) services. I would caution you against adding any application specific logic to this component as it would reduce the reusability of it in other applications which you may develop which may need to use the same component. I'm assuming right now your application logic mirrors the services provided by the CustomerService; simple CRUD operations. Now let's say you have some additional requirements such as: - When a customer is created, notify operations. - When a customer is deleted, notify operations. - Find all the customer's who have placed orders within a specified date range. You might be tempted to add this functionality to CustomerService and add the supporting functionality to CustomerDAO and Customer. Now let's say you need to develop another application which needs simple CRUD functionality for a Customer. Ooops. You can't use CustomerService. I have found that an additional application service layer provides the flexibility to add application specific logic leveraging a library of components instead of modifying them. For example, you might want to add a CustomerApplicationService which leverages the services provided by CustomerService. So for the example provided above, the CustomerApplicationService may collaborate with event listeners which respond appropriately to creating and deleting a customer. It may also collaborate with specialized DAO for retrieveing customer's using application logic criteria. It may also collaborate with value object assemblers to build value objects which cannot simply be represented by a single Customer. My point is that the additional layer provides a layer of abstraction which decouples the domain components from application specific logic which allows you to leverage your investments in these domain components, instead of modifying them to support additional application requirements. Don't forget that CustomerApplicationService should be an interface such that it can be implemented as a POJO (plain old java object) or maybe a delegate which hides a remote implementation. /robert Tim Christopher wrote: Hi, I'm currently designing a web application and as time progresses I keep on less convinced that my approach is correct.

Re: Struts Approach
So, this additional layer, in a Struts application, resides between the Struts classes (Actions) and your managerial facade? The Action instantiates/looks up a CustomerApplicationServiceImpl, which does CRUD via the CustomerService component but also manages (possibly by itself, possibly by delegation) app-specific notification logic, high-level view helper logic, etc. Is this correct? Yes. The application service becomes the core of the application specific logic. As such, it is the most volatile. Once the domain components (domain object, dao, and manager) are created to perform operations which are relative to their respective domain, then they shouldn't change much and essentially become a library of reusable components. Contrary to an application service which are subject to the whim of the business contraints. Effectively then, this layer decouples the managerial layer from, not Struts per se (though it does indirectly), but, from your implementation strategy (whether you use passive/active notification, how you filter read results, etc.) with respect to the business rules. Right? Yes. As mentioned above. Just to clarify, I consider the managerial layer to manage the domain component (domain object and its respective dao). If the implementation strategy refers to the implementation of the application specific logic, then yes. This strategy mainly falls out of my own experience with doing just what I cautioned against. I started developing domain objects using an ActiveRecord (see Martin Fowler) design pattern and then each time a new application requirement was added, I ended up adding a static method to my domain object. After a while my domain object was doing things wa out of its domain and consequentially not as reusable. I have found this to be a common pitfall in application development; especially as the application goes from simple to complex and critical. After some research (reading Core J2EE Patterns, Rod Johnson, etc...) and lots of refactoring, I started using the strategy I just described and have found the applications have been more scalable and most of the changes tend to be isolated in the application service layer. /robert Erik Weber wrote: Robert Taylor wrote: Tim, I think things look pretty good so far.

Re: Struts or SpringFramework
Kris, as others have already mentioned, you can use Struts and Spring together. Since you have four years of Struts you can leverage that knowlege in the presentation layer and use Spring for a light-weight container in the business/integration tier allowing it to provide services such as declarative transaction and dependency injection. Spring comes with built in support for Hibernate and JDBC. It has a terrific built in API for working with various persistence solutions. Spring allows you to wire up dependencies between those objects which collaborate with one another within a configuration file. These dependencies are established at application start up time so that your objects are all ready to go when they are invoked. Spring also provides the ability to declaratively define objects as singletons or as prototypes (non-singletons). The thing that impressed me the most was that it is non-intrusive. Your objects don't have to extend or implement any special interfaces to work with Spring (although they can implement certain Spring life cycle interfaces if they want to). To learn more about how to use Spring, you might want to download the Spring reference manual. Its easy to read and understand and will give you some great insight into those features it provides. http://www.springframework.org/docs/reference/index.html Good luck. /robert Eric Chow wrote: Hello, I have used Struts for four years.

Re: ActionForm with ArrayList - Validation Problem
This is a common and well documented idiom, but can be hard to
find in the archives ;)
The problem is that to display the form with the select list, you have
to prepare the select list before displaying the page.
When the user submits the form and validation fails, Struts will forward
to the input attribute value in the action mapping. If this value is the
.jsp instead of the action url which prepares the .jsp, you get the
behavior you describe below.
One solution, is to assign the input attribute value to be the
preparation action for the page.
Another solutions is to place your form in the session and override the
form reset() so that your customer list isn't wiped out when you submit
the request.
Another solution is if your customer list is unique to the user and
doesn't change, populate the list and place it in the session when the
user logs in and don't put it in the action form at all.
Another solution is if your customer list is static and global to all
users, populate the customer list on application start up
(ServletContextListener or Struts plugin) and place it in the
ServletContext as an attribute.

[Fwd: Re: ActionForm with ArrayList - Validation Problem]
This was a reply directly to me which I'm forwarding to the list so
future users can leverage the solutions provided in this message.
original message ---
Robert,
It is hard to find in the archives, but while I was reading the other
messages posted lately I found someone having the same problem and he was
redirected to http://www.reumann.net/struts/articles/request_lists.jsp which
is exactly what you are explaining me...
I guess I'll change the scope to session - which is probably the easiest way
to go for me for now. Hopefully that's not creating other problems...
Struts is a very nice technology, but there is so much to know and to
search...
Great list! And nice people always willing to help.
Thanks, BW.

This is a common and well documented idiom, but can be hard to

The problem is that to display the form with the select list, you have
to prepare the select list before displaying the page.
When the user submits the form and validation fails, Struts will forward
to the input attribute value in the action mapping. If this value is the
.jsp instead of the action url which prepares the .jsp, you get the
behavior you describe below.
One solution, is to assign the input attribute value to be the
preparation action for the page.
Another solutions is to place your form in the session and override the
form reset() so that your customer list isn't wiped out when you submit
the request.
Another solution is if your customer list is unique to the user and
doesn't change, populate the list and place it in the session when the
user logs in and don't put it in the action form at all.
Another solution is if your customer list is static and global to all
users, populate the customer list on application start up
(ServletContextListener or Struts plugin) and place it in the
ServletContext as an attribute.

Hi,
Not sure it is the best practice...
I have a for to edit a user called UserForm. This form contains a
popup
(select) with Customers.
I didn¹t find an easier way to include the data of the popup in the
UserForm:
Public class UserForm extends ActionForm {
protected ArrayList customer_popup;
public ArrayList getCustomerPopup() {
return this.customer_popup;
}
public void setCustomerPopup(ArrayList customer_popup) {
this.customer_popup = customer_popup;
}
}
So before editing the user and while building the form, I build
the form and
fill the ArrayList with the customers as well.
So far so good that works, but if I use validation, and the page
with the
form needs be reloading to tell me what went wrong, I have the
problem that
struts doesn¹t find the arraylist in the form anymore:

RE: Cross web app communication
Not really an observation, but more of how the Servlet specification constrains the use of forwarding to another resource. Forwarding is accomplished by using the RequestDispatcher.forward(). You can access a RequestDispatcher by calling Request.getRequestDispatcher() passing it the path name of a resource which is relative to the current servlet context. A redirect sends a status code back to the browser along with the url to which you wish to be redirected. The url may be relative to the same web app or a fully qualified url to a different resource. When you set the redirect attribute of the forward tag to true, then Struts will use Response.sendRedirect() to redirect the request to the specified resource which could be the same web app or a different web app. /robert -Original Message- From: Dakota Jack [mailto:[EMAIL PROTECTED] Sent: Sunday, December 12, 2004 2:02 PM To: Struts Users Mailing List Subject: Re: Cross web app communication Out of interest, Robert, would you mind expanding on this if you have more detailed observations that you could offer?

RE: action to action with form
You shouldn't be calling an Action from an Action. Action chaining is not recommended and is considered poor practice. Action classes are an implementation of Command pattern and as such should delegate to reusable business components. I would refactor your business logic embedded in Action classes into business components or application services. You can then call these from any Action class and they will be easier to unit test. If you want Struts to provide the ActionForm for each action then you must bind the ActionForm to the Action class in the action mapping. So if Actions, A, B, and C all need ActionFormC then you will have to define this in the struts-config.xml file. One way of maintaining state across actions is to place the ActionForm in session scope. robert -Original Message- From: Raffe Paffe [mailto:[EMAIL PROTECTED] Sent: Friday, November 19, 2004 7:18 AM To: [EMAIL PROTECTED] Subject: action to action with form Hi I have a system with some action classes that i need to call from my action class.

Subject: Prepopulate a DynaForm
I'm trying to prepopulate a DynaForm with some values - right now just
hard-coded, later should be taken from a DB. For that I'm using a
SetupAction, that is called to prepopulate the form, insert it into the
request and after that forward to the actual action for presenting the
form to the user.
Looks like this:
public class MediaArchiveSetupAction extends Action {
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response){
ActionServlet servlet = this.getServlet();
MediaArchiveForm mediaArchiveForm = new MediaArchiveForm();
mediaArchiveForm.setServlet(this.getServlet());
MessageResources messageResources = servlet.getInternal();
mediaArchiveForm.set(author, test);
// TODO: check why this doesn't work
request.setAttribute(mediaArchiveForm, mediaArchiveForm);
// this does actually work
request.setAttribute(test, dummy);
return (mapping.findForward(success));
}
}
Using this approach I always get a null pointer exception, leading me to
the presumption that the actual form-object isn't built.
Any ideas why?

RE: talking about paradigms
+1.
I have to agree with Daniel.
JSTL has allowed me to move a lot of view formatting
code outside of my page prep tasks.
In J2EE, .jsp pages are ViewComponents and custom
tags are ViewHelpers.
I think that JSTL gives you enought rope to hang yourself
with as well, especially with the sql: ../. But I understand
the business/marketing motivation behind them...CFML competition.
I mean, look at CFML applications, the use of the database access ViewHelper
is pervasive. But their business model is to enable page authors to easily
create business applications using a tag based model. I'm sure many of you
already are aware that there are large numbers of enterprise applications
written entirely in CFML. Personally, I would never want to develop nor
maintain such applications.
Anyhow, I digress...
I think the point is that the ViewHelpers used with regard for best practices
help move view logic into the ViewComponents and out of the controller and that
disciplined use of such technologies can provide better architectural
separation.

Subject: RE: talking about paradigms
I think the idea that MVC architecture should have a 'dumb view' is totally
wrong. The view should be as smart as possible.
MVC should separate the M, V and C. With a really smart view you dont have
to do any preparation for the view in the controller. If you have a dumb
view then you have to prepare the data in the model/controller so that the
view can cope with it. Surely this is wrong as you are doing view
processing outside of the view. Personally i think ALL view processing
should be done in the view: the view code (be it jsps, java, xml/xsl, etc)
should take model data, and produce a view of that data - and it should be
flexible.
The problem with a smarter (or better worded: more capable) view is that
people start doing things in the view which shouldnt be done there, such as
database access. I dont think this is down to a problem with the view
technology, just a lack of education on the users part. Arguing that the
view should dumbed down to stop this problem arising is like saying that
cars should only be able to do 70mph because that's all they can legally do.
For example, a poject i am responsible has a lot of code in the model beans
that was put there pre jstl for formatting things like dates, or text. So
you have getStartDate() which returns a date, and getFormattedStartDate()
which returns a formatted string. This code should be in the view as it is
purely for view purposes, but i made the decision to bodge it into the model
as it was nicer than using java code in the jsps. There are various other
methods - such as retrieving chunks of text with \n into br, which can now
mostly be handled with jstl.

c:out value=${library.books[25].page[5].title} / ?
(not sure about the syntax).
whats the problem?
MVC usually allows 'read-only access to model' for the view
Also the question is, what you expose to the view.
If you are afraid that somebody will misuse the library entries -
don't
expose them.
I suppose MVC was the reason for JSP EL not to allow arbitrary method
invocations. But I'd love to have such anyway ;)
...
And what about database access tags?
You mean the jstl tags? They are there for quick and dirty.
If you don't change anything in the database though, it still okay to
MVC.
If you don't want it, don't expose your database in the first place ;)
The problem is, that if you give a user the possibility to misuse your
framework - he will.
And EL gives jsps more power than a dumb view should have. And if your
view isn't just layouting out the data, but performing nearly complex
operations, it's not dumb anymore, and a smart view doesn't fit into the
MVC.
If the user is allowed to break the paradigm he will.
If you have an architecture, which is built on a paradigm (and any good
architecture is) you can't allow the developers to break the paradigm,
or
the architecture will stop working one day, without obvious reasons.
It's probably why there are no pointers in java, even pointers adds cool
features to the language.

RE: Use JSTL with html:multibox tag
Andy,
try this:
c:forEach var=service items=${services} varStatus=status
TR
TDc:out value=${service.name}//TD
TDhtml:multibox property=selectedServices[${status.index}]c:out
value=${service.status}//html:multibox/TD
/TR
/c:forEach
If the selectedServices is an array of Strings in your form,
and service.status == selectedServices[n], then the the checkbox
should be checked or atleast the tag should render the appropriate
HTML such that the checkbox should be checked.
I believe the problem is that the selectedServices is an indexed property.
If your container support JSP2.0 spec, then the above should work. If not,
then you will have to use the equivalent Struts-EL tag.
I think you see most examples using logic:iterate .../ because it supports
and indexed hook into indexed tags by setting its indexed attribute to true.
But the whole indexed property thing is hard to get your head around.
This link may give you some more insight.
http://struts.apache.org/faqs/indexedprops.html

BTW, the above code has not been tested.
If your selectedServices array is not the same length as your services
ArrayList,
then things are going to get ugly.

Subject: Use JSTL with html:multibox tag
Hi,
All the examples I've seen of using the above tag use the logic:iterate tag
to output to the page.
Does anyone have an example of how to this with JSTL?
My attempt is:
c:forEach var=service items=${services} varStatus=status
TR
TDc:out value=${service.name}//TD
TDhtml:multibox
value=${service.status}property=selectedServices/html:multibox/TD
/TR
/c:forEach
where services is an ArrayList in session with all available services and
selectedServices is the array of Strings in my form class.
The above displays all the values in services correctly but doesn't exhibit
any interaction between the checkboxes on the page and the selectedServices
array.
Thanks,
Andy

RE: Use JSTL with html:multibox tag
Yep. Scratch the indexed properties comment.
On each iteration, Struts will iterate over the
selectedServices comparing the selectedServices value
to the service.status value. If it finds a match, then it
will render the checkbox as checked. So, the fact that the
data structures are not the same size isn't a factor.
In Rick's example, he compares String to String. You may be
able to compare int to String or boolean to String because I think BeanUtils
performs
simple conversions for you, but byte to String... I don't know.

Hi,
Thanks for the input Robert, but the array will be shorter than the
arraylist whenever a checkbox is not selected.
I've had a look at Rick Reumann's Struttin with Struts lesson 3 which does
something similar and now have:
c:forEach var=service items=${services} varStatus=status
TR
TDc:out value=${service.name}//TD
TD
html:multibox name=serviceForm property=selectedServicesc:out
value=${service.status}/
/TD
/TR
/c:forEach
This is a step in the right direction but still doesn't work (the checkboxes
aren't checked when viewing the page even though they should be set). The
service.status field in the service class is a byte - does this have to be a
String?

Subject: Can't find property -- but it's there
We develop our Struts apps running them on a BEA Weblogic server installed
on our individual machines. When they run right, we deploy them to the
development server, a Unix box that everybody can access. Generally, this
works beautifully.
I'm now working with a Struts JSP page that works fine on my desktop, but
dies on the server. The immediate problem is a c:forEach ... tag, viz:
c:forEach items=${SeasAdjData.seasAdjs} var=seasAdjs
varStatus=stat
SeasAdjData is the form bean for this page. Two html-el:hidden... tags
precede the forEach tag, and there's no problem with them.
As I said before, there's no problem at all when I run this on the Weblogic
server on my desktop machine. But when I move it to the Unix box, I get:
javax.servlet.jsp.JspException: An error occurred while evaluating custom
action attribute items with value ${SeasAdjData.seasAdjs}: Unable to
find a value for seasAdjs in object of class
gov.bls.idcf.ppi.struts.SeasAdjData using operator . (null)
This seems to be saying that there is no getSeasAdjs() method on the
SeasAdjData object. But it is definitely there, and it's found when I run
the app locally.
The Unix version of Weblogic is in fact running on a cluster of two Unix
machines. I've used c:forEach *many, many* times before, without incident.
What might be going on here?

RE: Can't find property -- but it's there
Yes, but it may be possible that the ClassLoader (for whatever reason) has a cached version of the older class and it is not loading the new class when the web app reloads. Have you tried rebooting the application server on the development machine? If the problem still occurs on the dev. box after the application server reboots then you could rule out the ClassLoader issue. It may be a pain in the ***, but it would eliminate a path. One other thing to check, is to make sure you don't have any older versions of that class in the system classpath. I believe ClassLoaders are hierarchical and classes in the parent classpaths will be loaded instead of those in the child classpaths. From java.lang.ClassLoader: The ClassLoader class uses a delegation model to search for classes and resources. Each instance of ClassLoader has an associated parent class loader. When requested to find a class or resource, a ClassLoader instance will delegate the search for the class or resource to its parent class loader before attempting to find the class or resource itself. The virtual machine's built-in class loader, called the bootstrap class loader, does not itself have a parent but may serve as the parent of a ClassLoader instance. Ofcourse different application servers may have different implementations of ClassLoader employing different search algorithms. robert -Original Message- From: Slattery, Tim - BLS [mailto:[EMAIL PROTECTED] Sent: Wednesday, November 10, 2004 2:20 PM To: 'Struts Users Mailing List' Subject: RE: Can't find property -- but it's there On 2004-11-10 at 14:04:38 -0500, Slattery, Tim - BLS wrote: Just a guess Tim, but is it possible that the ClassLoader used on the development server and the ClassLoader used locally are loading different versions of SeasAdjData?

RE: What is a good Struts application?
I would take some time and do a little research
on the MVC architecture and web applications.
You want to avoid business logic in your view (.jsp) and leverage
other J2EE components for authentication and authorization.
So, for the example below, you may want to investigate the
the use of container managed authorization/authentication or
the use of a Filter (SecurityFilter).
The general idea is to protect resources using either technique
and redirect to the appropriate resource if the user passes the login.
Else, redirect to the approprate page.
For the example below, you would want to protect all pages in the banking
application unless the user has been authenticated and is authorized to view
the page. You could use one of the above approaches to do that.
Next, once the user has been authenticated and is authorized to view the page,
you could define a Struts action which would be invoked prior to viewing the
page;
ShowUserAccountList. This action would delegate to the appropriate business
logic
which would retrieve the necessary user information and place it in a JavaBean
which you could place in request scope. ShowUserAccountList would then look up
a forward mapping which would allow the controller to forward to the
appropriate .jsp page, where you could use either JSTL or
Struts custom tags
to iterate over the user account list and render the appropriate information.
There are plenty of examples and advice for this type of architecture.
You can start here:

Subject: What is a good Struts application?
hi,
I am a newbie to Apache Struts. I'd like to know what a good Struts
application looks like.
In our JSP pages, should we try to avoid embedded java code but use tags?
For example, i have an index.jsp page for my banking application.
When a user comes to this page, it displays the login form. When a user has
already logged
in, it displays the user's account list. The user information is saved in the
session as
an instance of my User class. I wrote my index.jsp as the following:
%
User user = (User)session.getAttribute(USER);
if (user==null) {
%
html:form action=Login
Login Name: html:text property=loginName size=16/br/
Password : html:password property=password size=16/br/
/html:form
%
} else {
Iterator iter = Account.getAccountList(user);
int count = 0;
while (iter.hasNext()) {
count ++;
Account account = (Account)iter.next();
%
%= account.getName() %
(created on %= account.getCreatedDate() %)br/
%
}
%
Total %= count % accounts found.br/
%
}
%
Here are my questions:
1. My business object is the Account class. It provides
a static method getAccountList(User user) to get an iterator
of all the accounts of the given user. I am calling this method directly
in my index.jsp file, but it does not seem to be a good struts programming
style. So what is the preferred way for doing this?
2. I used embedded java code for checking whether a user has logged in.
Should i use tags in the bean taglib or logic taglib to get an object from
the session and check it?
Thanks for any reply.

Everything works greatly except for that
html:checkbox property=propName

As the JSP and the related specifications mature, new standards like JSF and the JSP Standard Tag Library (or JSTL, which uses simple tags to encapsulate the core functionality common to many JSP applications) are emerging. Following are some of the advantages to using the new technologies as an integrated whole: * Cleaner separation of behaviors and presentation. With the separation of tag, renderer, and component, the roles of page authors and application developers in the development cycle become better defined. * Changing the presentation for a component does not have an avalanche effect. Now you can easily just change the renderer. In the traditional MVC model, since this separation did not exist, any change in tags needed changes to the business logic as well. Not any more. * Renderer independence. Or restated, protocol independence by reusing component logic for multiple presentation devices with multiple renderers. The ability to use different renderers eliminates the need to code the entire presentation tier for specific devices. * A standard for assembling and reusing custom components. JSF thinks beyond forms and fields and provides a rich component model for rendering custom GUI components. Using JSF you can customize the way each component looks and behaves in a page. Developers also gain the ability to create their own GUI components (like menus and trees), which can easily be included in any JSP page with simple custom tags. Just like the Java front-end GUI components provided by AWT and Swing, we can have custom components for our Web pages that use their own event handlers and have customizable appearances. This is GUI nirvana for the Web tier! Struts is a framework that already possesses a large customer base. Many IT departments have recognized the value of this MVC framework and have been using it for quite a while. JSF doesn't possess the equivalent of Struts's powerful controller architecture, as well as its standardized ActionForm and Actions (with their declarative capabilities). When you integrate Tiles into the mix, you give yourself the ability to reuse and change corporate layouts in a seamless manner. The challenges of migrating JSF-enabled Struts applications are two-fold. First, Struts tags are not JSF-compliant. In other words, they do not extend the UIComponentTag as mandated by the JSF specification, therefore, JSF cannot interpret and associate UIComponent and Renderers with them. Second, there is no link between the FacesServlet and Struts RequestProcessor. In a Struts application, the RequestProcessor manages the show with the callback methods into ActionForm and Actions classes. Getters and setters for ActionForm properties and validate() are the callback methods in the ActionForm. For Action, execute() is the callback method. Unless the RequestProcessor gets invoked, the callback methods in Struts ActionForm and Actions classes do not get a chance to invoke the business logic.

Yep. I usually bunch all action type stuff in the action package. Like forms, action utils, value objects used in actions, etc... I guess it more or less represents the presentation part of the package and the service represents the business part. I only see a need to dissect it into these two because the actions should only need to talk to the service layer.

RE: Idea for chain and DB transactions
Sean, have you looked at Spring? It uses AOP and you can set up transactions declaratively. I'm just starting to investigate using Spring and I'm really impressed. Like you I had a requirement to demarcate transactions at a high level so that all business objects within the transaction were subject to the same transaction semantics unless a business object explicitely needed to be isolated. I ended up creating a Transaction framework of sorts which uses ThreadLocal to propogate the Connection to my DAO's. All DAO's that need to be included in a transaction had to subclass a TransactionalDAO which knew how to access the current TransactionContext from ThreadLocal. It has worked for a couple years now, but its not that clean or elegant. That's why I was so excited to read about Spring and IoC. It does all that stuff for you. robert -Original Message- From: Sean Schofield [mailto:[EMAIL PROTECTED] Sent: Friday, September 17, 2004 2:44 PM To: [EMAIL PROTECTED] Subject: Idea for chain and DB transactions I have a problem and a proposed solution. I would greatly appreciate any feedback about the proposed solution. Problem: === I'm currently using a Struts application with a connection pool (using DBCP as supplied by Tomat). When a database update is needed, the Struts actions will call the facade which will talk to my service layer (currently POJO's which handle business logic.) My service layer in turn talks to the appropriate DAO. Each of these DAO's extends from a common abstract class that provides basic functionality including obtaining a connection from the DataSource (via the pool). A key aspect of my design is that some updates are in distinct areas of the database and so I have different DAO's for each area (ex. one for workflow on for document.) As currently implemented I am unable to take advantage of transactions because the two DAOs will be getting a connection indepently from the pool and they will most likely not obtain the connection each time. If I could just get the same connection each time, then I could use setAutoCommit(false). Proposed Solution: == I'm thinking I could set up a few chains for the various kind of updates. The chains would be called by the POJO service layer (instead of calling the DAO's directly.) The first Command in the chain would be to indentify all database updates in the chain as needing transactions. This would be done through a static method on a new object called TransactionManager. Basically I would have a hashtable that would maintain connections for the duration of the chain. The connections would be stored by the current thread (use that as the key to the table.) Then when a command down the line needs a database connection, it would first check to see if there is one already set aside for it to use. Actually the command would call the DAO and the DAO would check. The command would also be decorated by a custom wrapper so that if the DAO's try to close the connection, I'll ignore it. Then when the chain does the post processing in reverse order. So the last clean up step will be to check for my custom DAOException. If there is one, then rollback, otherwise commit. Finally, the connection is removed from the TransactionManager. I think this might be crazy enough to work. I know we could allways use EJB and get transactions but that might be overkill since the volume is very light (this is custom software for a government agency not ecommerce.) Please let me know what you think. A big question I have is about storing and retrieving the datbase connection using the current thread as the key to a hashtable. Also, I know that I will have to be careful with thread synchronization. Thanks, sean - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Validator with DispatchAction...help!...newbie
ValidatorForm, ValidatorActionForm, DynaValidatorForm, and DynaValidatorActionForm allow you to leverage the validation framework in Struts. How you use DispatchAction determines what you need to do to make it work with the validation framework. For example there are two basic approaches: 1. Differentiate different validation routines based on form name. Using DispatchAction you could use the same form and identify it with different names in the struts-config.xml file. You can then ensure that each action mapping using the DispatchAction used the appropriate form name to invoke the appropriate validation rules in validation.xml. 2. Differentiate different validation routines based on action mapping. Using DispatchAction you could use the same form with the same identity. You can then use different action mappings which all map to the same DispatchAction using the same form. Each unique action mapping would then invoke the appropriate validation rules in validation.xml. There are other variations of DispatchAction such as MappedDispatchAction and LookupDispatchAction. Each of these might be leveraged differently to work with the validation framework. I've yet to use them, so I can't offer any advice; however, recently, there have been some healthy threads on both. Just don't ask Rick about LookupDispatchAction and you'll be okay :) Now, it gets kind of tricky when you want to use DispatchAction (or some variant there of) to perform different validation routines using the same form name and the same action mapping. This is typical when you have a single form with multiple buttons, where each button invokes a different operation on the DispatchAction and you want to use different validation routines for each operation. Since validation routines basically key off of the name attribute of the form element in validation.xml, you can modify/override the getValidationKey() in ValidatorForm or ValidatorActionForm to return a name including the invoked operation. There are probably other ways to do this and most likely more elegant. I think you can also use the form name in conjunction with the page attribute as the validation key but I haven't done this yet. Digging around the source code always helps me to understand how things work. robert -Original Message- From: O.

Pilgrim [mailto:[EMAIL PROTECTED] Sent: 08 September 2004 07:12 To: Struts Developers List Subject: [ANN] Bridgetown IoC Framework Hi I have been quietly working on my own Inversion of Control lightweight framework over the last couple of months. My itch was scratched when I suddenly realised that ``Commons BeanUtils'' and ``Common Digester'' could be simply combined together into a bean assembly factory. An assembly factory could manage service beans in a lightweight container. Services could then be retrieved by name, and one doesn't have to worry about connecting different services together. Experiments showed that this idea was pretty cool and have implemented property and method dependency injection (aka ``BeanUtils'' and ``MethodUtils''). [Constructor injection is on the todo list. ] I am at the point where the current codebase is stable enough for development, but if I want the container to be more useful, then I need to open- source the project. It would allow others to write Dynamic proxy service beans, integrate with Struts 1.2/2+, or extend with AOP library, or whatever persistence layer EJB 3.0 decides to become. It cannot be down by just one man writing software. As an independent consultant I simply have not got the time to build everything. Moreover, I intend to follow the Struts style ``open integration'' philosophy that should allow Bridgetown IoC container to be added any other framework. (I intend add support to the Expresso Framework in the near term, since I am a core committer there) So my simple IoC Test Container became ``Bridgetown IoC''. I uploaded the source code to ``Sourceforge'' and slapped on it an Apache License 2.0 badge. The software is ALPHA quality but it compiles and run with Eclipse SDK 3, and there are junit test and a couple of examples. `` http://bridgetown.sf.net '' is the hook. I'd like publicly thank the man, Craig McClanahan, for his two inventions `BeanUtils' and `Digester'. Without those two components it just wouldn't have happened.

RE: Proper place for validation

Let's say I have a registration page where user inputs his/her information for a new user account. There's a field for e-mail address. On one level that information is validated on the ActionForm, for things such as - field is not left empty, if it is required - field is a valid e-mail address That much seems quite clear. But where should I put a check that ensures that same e-mail address is not already used by an existing account? On the other hand, I could put it in the registration action, because checking that is (kind of) user-input validation, and action is a natural place to do this. On the other hand, I could put it in my business class. The pros for this would be smaller and simpler action code, and reuse if same check is needed with different actions. Any suggestions?

RE: SecurityFilter Question?
I haven't been following this thread too closely but
I know its been some what long so if this solution has
already been proposed, I apologize in advance.
We use SecurityFilter and an additional filter which
checks for the Principal in the request. If the Principal exists,
then we can be assured that the user has successfully logged in; at
which point we check to see if the required information is in the
session. If not, then we persist the required information into the session.
If so, then we do nothing. In either case we allow the filter chain to proceed.
It has worked quite nicely so far.
Principal principal = req.getUserPrincipal();
if (principal != null) {
if (req.getSession().getAttribute(requiredInformation) == null) {
// do other login stuff here
}
}
chain.doFilter(req, res);

Can't u do this using an Action? Say, accessing /admin/LogAction.do
invokes SecurityFilter, after authentication by SecurityFilter is passed,
go directly to LogAction as below
The problem comes if the user bookmarks a url like /user/abc.do, starts
up their browser and goes directly to the protected URL. The security
filter will take them to the login form, they submit username/password
and seucirty filter authenticates them. Once they are authenticated
they are redirected back to /users/abc.do - they don't pass through
LogAction at all. So I normally have a filter that makes sure the bean
is in session from where ever they are called.
You don't have to use a filter though, you could make a base action that
does puts the bean into session and have all your actions sub-class that
one.
Using action to put bean in Session after SecurityFilter, how is that
possible when after authentication by SecurityFilter, u taken right
back to /user/abc.do where u 1st request it and doesn't pass
through to action attribute as specified in action-mapping of

My LogAction extends DispatchAction and will try
to put User bean in session. --
or
action
path=/admin/Logon.do
type=org.apache.struts.actions.ForwardAction
parameter=Welcome.do/
action

BTW, how wud u use html:form to display
login fields?
I can't get struts tag to work with login fields
except for using things like:
form action=j_security_check method=POST
Username: input type=text name=j_usernamep
Password: input type=password name=j_passwordp
input type=Submit
/form
--
Ok, using filter (as u said) after SecurityFilter wud solve this simply but
I like to stick with pure Struts approach if possible.
Thanks
