Re: JSF and Struts Actions
This is so cool. I was hoping for this sort of thing. This is getting close to grown up. I wish I could see this stuff now. Man! Don't forget that JavaServer Faces has a two-level architecture -- user interface components that are render-independent, and renderers that construct a particular markup language. HTML is only one possbile output format, unlike Struts tags where (in JavaServer Faces terms) the rendering markup is baked in to the UI component tags themselves. Craig McClanahan Hmm.. I don't see why this is cool yet. The last time I looked at JSF, it appeared to be an attempt at re-invention of GUI concepts on the server side. Will the sophistication of such controls eventually approach what is available on a reasonable desktop PC today? And even when it does, the fact that server based UI's are going to involve all sorts of network/latency issues pre-dominate.. no? It is clear that rich-client based approaches offer richer interaction than web pages today, and embedding such controls in web pagesis possible (using MSFT amongst others) today. Innovative approaches exploiting java also currently exist (see nexaweb, thinlet etc). I saw these latter as re-inventing X11 (since they are focussed on the protocol that transmits bits between the server and client), and now JSF is proposing to redo the same but at the Xt or Motif level (to use a much-abused layer separation). Personally speaking, I find more work at the back-end interesting but I would like to know how it would impact the front end. The stuff we (as programmers) have trouble with really is still in the front end.. take a sampling of struts questions/traffic and I really wonder what percentatge of the traffic has to do with layout, jsps, event, security, controls (calendar/pagination etc.) .. all GUI/HTML/frontend stuff. Will JSF make writing such front-ends easier.. and if so, how? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: DateUtilities for ActionForms?
I wrote a simple conversion method and pass the Strings through - no hassle
at all. Given the String Jan 1, 2003:
Calendar date = getDate( string );
private Calendar getDate( String string ) {
Calender cal = Calender.getInstance();
String formatted_date = null;
String[] months = {
Jan,Feb,Mar,Apr,May,Jun,Jul,Aug,Sep,Oct,Nov,Dec };
StringTokenizer st = new StringTokenizer( string );
String str = st.nextToken();
for( int i; i months.length; i++ ) {
if( str.equalsIgnoreCase( months[ i ] )) {
month = i;
break;
}
}
String temp = st.nextToken();
StringTokenizer token = new StringTokenizer( temp, , );
date = ( new Integer(( String ) token.nextElement() )).intValue();
year = ( new Integer(( String ) st.nextElement() )).intValue();
return( cal.set( year, month + 1, date ));
}
Easy, heh? You could also use regular expressions if you are using JDK 1.4.

Re: Why do ActionForms allow non-string properties?
we'd be down to a single XML to define the form, the input properties, and their validators. +1 .V Ted Husted wrote: Steve Raeburn wrote: *BUT* there should be a bloody big health warning on the ActionForm documentation that says only ever use Strings! Whether or not to only use Strings only matters if you care about capturing non-string input in a non-string field. Craig always felt that this use-case is very important, and many people agree. In practice, though, sometimes it doesn't matter. If they put AZ1234 in a field, the BeanUtils can quietly convert that to either null or zero. If the field is required, then they can be required to put in a valid, non-zero entry into it. For some clients, this is acceptable. As a consequence, if you have perfectly good business interface that you can otherwise apply to a ActionForm -- there you go, one less JavaBean protocol to maintain (at client's expense). Many people never even realize that there is any type of restriction here. A lot of application only use Strings to begin with. Or, the numbers are input through controls that put the numbers in for people. Or, the application requires clients to use JavaScript and a runtime Javascript keeps the focus on the field until they enter a valid number. I'm using some non-string ActionForm properties in my current application, and it's working just fine. We have exactly two fields that need actual numbers, and they are even required fields. For extra credit, I may try and snag invalid input and see if I can pump it into a validation message (AZ1234 is not a valid number). (Which, IMHO, is more appropriate than repopulating a field with invalid input.) In the occasional case where I need to accept string Input for a complex field, like a Date, I have a binary field declared on the business interface, and the use helpers on the ActionForm to convert the field back and forth. But, with DynaBeans, this is becoming less and less of an issue, since it is very easy to just use DynaBeans as the missing HTTP data entry buffer and then pass the validated input off to a business bean. Though, there is still a ton maintenance going on here. We have the properties defined in the HTML form, and the struts-config, and in the validator.xml, and then in some type of corresponding property in the business bean, not to mention the actual data store. So to add a field, we have to update five (or more) components. The next step might be to try and combine the validator and DynaBeans definitions somehow, so that they can be maintained together. For many people, all the ActionForms do is validate input, which begs a single component. Heck, I could even imagine a tag that could generate many forms for you. If we were already defining the field, the validation, and the message, why not toss the control into the soup. The tag could look up the form definition and render the fields in order, using the specified control type. This wouldn't work for every case, but it might work for a great number of forms. So, then we'd be down to a single XML to define the form, the input properties, and their validators. So, then if you were using Hibernate, for example, you could end up maintaining two XMLs (one for Struts and one for Hibernate), along with the business entities (that are the point of the excersice). With Dynamic Forms, most of the HTML pages would be self-maintaining =:0) -Ted. Steve Raeburn wrote: OK, I definitely get the fact that you might need helper methods in addition to your html input properties. I guess I've just gotten into the habit of making ActionForms as simple as possible (actually I prefer DynaActionForms) and doing any conversions or manipulation in the Action.

If the field is required, then they can be required to put in a valid, non-zero entry into it. For some clients, this is acceptable. As a consequence, if you have perfectly good business interface that you can otherwise apply to a ActionForm -- there you go, one less JavaBean protocol to maintain (at client's expense). Many people never even realize that there is any type of restriction here. A lot of application only use Strings to begin with. Or, the numbers are input through controls that put the numbers in for people. Or, the application requires clients to use JavaScript and a runtime Javascript keeps the focus on the field until they enter a valid number. I'm using some non-string ActionForm properties in my current application, and it's working just fine. We have exactly two fields that need actual numbers, and they are even required fields. For extra credit, I may try and snag invalid input and see if I can pump it into a validation message (AZ1234 is not a valid number). (Which, IMHO, is more appropriate than repopulating a field with invalid input.) In the occasional case where I need to accept string Input for a complex field, like a Date, I have a binary field declared on the business interface, and the use helpers on the ActionForm to convert the field back and forth. But, with DynaBeans, this is becoming less and less of an issue, since it is very easy to just use DynaBeans as the missing HTTP data entry buffer and then pass the validated input off to a business bean. Though, there is still a ton maintenance going on here. We have the properties defined in the HTML form, and the struts-config, and in the validator.xml, and then in some type of corresponding property in the business bean, not to mention the actual data store. So to add a field, we have to update five (or more) components. The next step might be to try and combine the validator and DynaBeans definitions somehow, so that they can be maintained together. For many people, all the ActionForms do is validate input, which begs a single component. Heck, I could even imagine a tag that could generate many forms for you. If we were already defining the field, the validation, and the message, why not toss the control into the soup. The tag could look up the form definition and render the fields in order, using the specified control type. This wouldn't work for every case, but it might work for a great number of forms. So, then we'd be down to a single XML to define the form, the input properties, and their validators. So, then if you were using Hibernate, for example, you could end up maintaining two XMLs (one for Struts and one for Hibernate), along with the business entities (that are the point of the excersice). With Dynamic Forms, most of the HTML pages would be self-maintaining =:0) -Ted. Steve Raeburn wrote: OK, I definitely get the fact that you might need helper methods in addition to your html input properties. I guess I've just gotten into the habit of making ActionForms as simple as possible (actually I prefer DynaActionForms) and doing any conversions or manipulation in the Action. Given your example, I would use a DynaAction form to define the String input properties and have a completely seperate EmployeeDTO bean which I would populate in the Action. By having helper methods on the ActionForm you run the risk of infecting it with business logic. I haven't encountered a situation where it hasn't been possible to keep the ActionForm extremely simple. But I accept there might be situations that would warrant it. *BUT* there should be a bloody big health warning on the ActionForm documentation that says only ever use Strings!

RE: Why do ActionForms allow non-string properties?
Though, there is still a ton maintenance going on here. We have the properties defined in the HTML form, and the struts-config, and in the validator.xml, and then in some type of corresponding property in the business bean, not to mention the actual data store. So to add a field, we have to update five (or more) components. In my XDoclet-enabled apps, if I had a new property, I only have to add it in two places - in my POJO and in my JSP. validation.xml is generated, as well as the ActionForm. Using Erik Hatcher's StrutsGen Tool, you can also generate a skeleton JSP from the generated ActionForm - but this is only logical to do the first time. I don't know if it'll ever be possible to eliminate the editing of the JSP - unless we add an XML file or something in the ActionForm that specifies field order, field type, etc. Still, there's so much custom stuff (label taglib, javascript pop-up calendars) that I put into forms, I doubt this will ever be possible. IMO, XDoclet is the best thing that's happened to Java Development since Ant. Matt - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Form validation over multiple pages - Solution Found - Weird
Could anyone tell me if I am right in what I think the problem is here? I use a web-filter for ssl. I use form-beans that have session scope in a wizard, one of whose steps requires ssl.

It was good to know people had it working. I've got it to work now. The reason it wasn't working was that for all secure pages I use a ssl filter which takes any request mapped like /secure and sends it over ssl. For example, if I want to send the info for the first jsp I send it to: html:form action=/secure/validateStep1.jspa the weird thing is - the form object isn't staying in session scope if I use the ssl filter and so the second page's validation was failing because the object wasn't in session scope anymore. However, once I removed the secure it works fine. Reading other threads, I think this might be to do with a redirect ( if the filter is doing a re-direct, then a new http request might be getting created and thus a new form object gets created ) Anyway, thanks for all the help, and if anyone knows how I could continue using the filter and keep the form object in session scope I'd really appreciate any ideas!

RE: Why do ActionForms allow non-string properties?
Still, there's so much custom stuff (label taglib, javascript pop-up calendars) that I put into forms, I doubt this will ever be possible. It's called a code generator and its already been done in other environments. The trade-off is that you lose some of the really fine control that is so attractive to programmers. You have to believe before it can happen! Most of the programmers I know give up on the generators in the belief they can program it faster. They probably can.

Hi, guys We are using multi modules in Struts. We find a prolem in finding the global forward specified in the default config. For example, our UserProfileThanksAction is configed in profile module and home is the name of a global forward specified in the default config, when we say return mapping.findForward(home); in UserProfileThanksAction the mapping is not able to find home. We are not using the switch action. Instead we are specifying modul prefix in config file. For example, What is the appropriate way to find global forwards in individual module ?

In fact there is an already-written drop-in filter that times requests and logs them in the excellent article at http://www.javaworld.com/javaworld/jw-06-2001/jw-0622-filters.html You could easily modify this code to store the results in a session-scoped bean and then read this data from a JSP later in the user's session. You wouldn't be able to do it in a lesser scope because you record the time *after* the request is processed (after the chain.doFilter() method is called).

RE: Why do ActionForms allow non-string properties?
:-D I had to chime in. I use complex objects in my forms so extensively because it makes my life easier when it comes to communcating with my business logic layer. It actually cuts down on the amount of manual transalting I have to do from one layer to another. It also cuts down on the amount of code I am writing. I DON'T think we should make a huge statement about Strings only. Strings do no handle all the situations that exists out there and often can be inhibiting when working with nested objects. It's silly to create String only beans to use in your forms and then communicate with the other layers by providing conversions between your string beans (no pun intended) and complex beans. YUCK!!! How about 10X more code and more code means more potential errors. I think that we should emphasis both scenarios. We should provide a reccommended way for using forms with complex (nested) objects and using basic flat String based (non-nested) forms.

Application Service Providers and Struts
Here's is another what would you do in this situation? inquiry. We're an ASP and I would really like to leverage Struts for the controller (I don't intend on leveraging the view aspect). Our biggest issue with leveraging Struts is that we need to be able to handle customer-specific customizations at the presentation level and possibly in terms of workflow as well. I also want to be able to do a hot-deploy of new overrides for customers without affecting other customers ability to interact with the web-site. Let's seperate out the issue of about hot-deploying classes (which, coincidentally, was recently covered in a recent thread here). My initial thought was ok, so I will provide customer-specific action mappings. The basic idea was to have a set of default action mappings defined and then have customer-specific overrides for the non-default stuff. Currently we are not planning on leveraging modules. That would certainly add a dimension of complexity on to this. Here two ways to do this; both require modest modification of the Struts framework (which I could do via overriding). I'd love feedback on these or any other suggestions. Solution 1: override the processMapping method in the RequestProcessor to look for the customer ID in the session object (this is guarenteed to be there anyway). I could maintain ActionMapping tables for each customer and one for the default. Solution 2: Have override ActionServlets that maintain their own action mapping tables for specific customers. In other words, one ActionServlet for each customer and one default ActionServlet (the customer specific ones delegate to the default if it's not found). One big issue with this is that ActionServlet is really meant to be a Singleton so this would have to be resolved somehow (ugh!) Any thoughts on this? If you were an ASP that needed to support this kind of customization, what would you do? I really like the notion of maintaining this in the controller level... it makes a lot of sense to me at an abstract level but Struts, as it stands, does not seem well suited to this particular application (of course I may be missing some slick way to accomplish this which is, of course, why I am here :-) - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

The Struts way? Well, isn't a request just a request whether it's passing through the Struts framework or not? If you're looking to measure at the granularity within the framework itself then a filter may not give you that granularity.

Our biggest issue with leveraging Struts is that we need to be able to handle customer-specific customizations at the presentation level and possibly in terms of workflow as well. I hate to plug our site again so soon after making the announcement, but we had to do this very thing. Check out the following links: http://packaging.hotels.com/packaging/?TSRC=1 http://packaging.hotels.com/packaging/?TSRC=2 (These work up to TSRC=5) We use a modified versions of Tiles and several of the Struts HTML tags for this: instead of pulling various items (text, image locations, tiles, etc.) out of a resource bundle we pull them out of a DB. As you can see, this allows for a large degree of customization, with different stylesheets, images, buttons, and tiles use to build various elements within the page. By keeping true to the MVC paradigm, this has allowed us to deploy the web app with a substantially different look and feel for a given affiliate. My initial thought was ok, so I will provide customer-specific action mappings. The basic idea was to have a set of default action mappings defined and then have customer-specific overrides for the non-default stuff. Any thoughts on this?

If they only want to do look-and-feel changes, then this will be relatively straightforward to implement. Customizing business flow, however, could be quite a challenge, especially given various dependencies that usually crop up. I don't think it would be unreasonable -- again, depending on your exact requirements -- to set limits on what can and cannot be customized. -= James - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Nesting logic tags
Well, I'm not an expert, but I can try. First, the obvious stuff I assume you know. ansm must be a bean you've exposed, right? If so, then it must have a getter method, getEntryType(). In order for the contents within logic:equal to appear, this method must return subformat [or group]. I *think* that if the ansm bean were not exposed, or you didn't have the getter, there'd be an error, so I guess that's not it.

Re: Populating Value Objects for the Business Tier
I've been playing #3 (Just included the value objects in the form) and run into one of those things that probably makes people break into tears. I have int types in the value object... And since they cannot be null, when the form is prepopulated or repopulated they appear as 0 instead of being blank or what the user entered. Sad. -jdr On 5/28/03 9:53 PM, Andrew Hill [EMAIL PROTECTED] wrote: 2 3 generally end in tears. They sound nice, but when you get down to the fiddly bits you will find it more problematic than you expect. As you mention, the action form is very much a view object. For a start everything in the actionForm will be strings, while your business object probably will not be. Secondly, while there is considerable overlap between your value object and your form, you will find (especially as your ui gets more complex) that the correlation is not 1 to 1 and that you are exerting a lot of effort to try and keep the two the same. Approach 3 is probably the worst - unless its for read only display - in that if the user enters a value that doesnt convert to your value objects property type you will want to redisplay the offending value string the same as the user typed it for them to correct it. Your best bet is to use approach 1. You may be interested to note that the BeanUtils class does have some methods that can make life simpler for you - copying property values and doing type conversions automatically (if I recall correctly).

We currently have three techniques we've though up and I'm wonderful if anyone has a strong opinion on which one may be the best and why. The basic problem is that the user enters information into a form. The form is a presentation object, and should not be passed to the business layer. So it's information needs to be in a presentation-agnostic interface before being passed to the data layer. 1) Have the action class copy information from the form to a value object. Have a view helper copy information from the value object into the form (for pre-population) 2) Have the form implement a value-object-like interface. The business layer accepts objects with these business interfaces. This way it is possible to pass the form objects to the business layer without the business layer knowing that they are presentation objects. 3) Have the form simply include value objects as properties. Then use the nested taglibs to populate the value objects. This way the Action can just pull the value object off directly and pass to the business layer. A view helper can just set the value object on the form. -jdr - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Objects in session scope, good or bad practice?
Hello, I would like to hear your opinion about the following: In my webapp, when a user clicks a link, a custom type object is created in an action, then control is forwarded to a jsp view that shows some data taken from that object and a form where the user can enter some information and then submit the form. In the action associated with the form I would like access the previously created object again. As the form submission is a new request, I store the object as attribute in session scope in the first action to be able to access it in the second action. When the second action completes, I remove the attribute from the session. Is it good or bad practice? I really would like to use request scope instead, but I don't find a way to do that. Normally hidden fields are used in that case, but they can only be Strings, right? What I don't like so much about session scope is, that if a user chooses not to submit the form, the second action will not remove the attribute with the object, and it will hang around until the session expires or the user clicks the link again and submits the form. I found some posts where similar topics where discussed, but I'm still not sure if it's the right way what I'm doing or not. Thanks very much in advance!

Re: Forwarding to Action
After consulting the api, and browsing through the list archives again I was able to discover that in order to instantiate a new instance of a DynaActionForm to set within the request the following code is required, which is listed below. Hopefully this will be helpful to someone in the future with the same problem. However, after successfully managing to work my way through this problem, I have run into another problem.

RE: time to do action
There must be a struts way to do it surely.
The RequestProcessor is a global controller for all Actions, its
methods are
accessed in a sequence, some before the action some launching the action,
some after. Surely this can be used to time the Action.
Anyone?
Okay a global way, using the RequestProcessor:
// add the time req'd to process action into request attribute
protected ActionForward processActionPerform(etc) throws etc {
long start = System.currentTimeMillis();
ActionForward fwd =
super.processActionPerform(req,res,action,form,mapping);
long end = System.currentTimeMillis();
String time = Double.toString(((double)(end-start))/1000);
req.setAttribute(time,time);
return fwd;
}
### HOWEVER! ### When you have a simple action mapping like this:
action path = /JSPPlease
name = myForm
forward = /WEB-INF/jsp/aJSP.jsp/
It does not work.
Doesn't the Controller operate in the same way here?

RE: Objects in session scope, good or bad practice?
I do this all the time - it's why the Servlet spec provides for environmental variables (request, session, context). Use it to your advantage. Unless you are hosting a very high-traffic site, any session objects that hang around until expiration are not going to degrade performance or cause a problem, especially on a high-end machine (like my laptop :-) ). You are wise, however, to be cognizant of providing a means for dereferencing the objects when possible. Craig does this in the examples that come with the download. Mark -Original Message- From: Torsten Römer [mailto:[EMAIL PROTECTED] Sent: Friday, May 30, 2003 2:47 PM To: [EMAIL PROTECTED] Subject: Objects in session scope, good or bad practice? Hello, I would like to hear your opinion about the following: In my webapp, when a user clicks a link, a custom type object is created in an action, then control is forwarded to a jsp view that shows some data taken from that object and a form where the user can enter some information and then submit the form. In the action associated with the form I would like access the previously created object again. As the form submission is a new request, I store the object as attribute in session scope in the first action to be able to access it in the second action. When the second action completes, I remove the attribute from the session. Is it good or bad practice? I really would like to use request scope instead, but I don't find a way to do that. Normally hidden fields are used in that case, but they can only be Strings, right? What I don't like so much about session scope is, that if a user chooses not to submit the form, the second action will not remove the attribute with the object, and it will hang around until the session expires or the user clicks the link again and submits the form. I found some posts where similar topics where discussed, but I'm still not sure if it's the right way what I'm doing or not. Thanks very much in advance!

Re: Populating Value Objects for the Business Tier
Plus you have security issues, it is simple to spoof the form submission and set properties other than the ones that correspond to form fields (that is, if there are any other properties on your value object). I copy properties using BeanUtils where possible, and for cases where that doesn't work (there are many) I do it manually in the Action. The cases where BeanUtils.copyProperties() doesn't work are when the business object has nested properties, or where the type of the property is not one of the native types. If anybody has a nice solution to these I'd like to hear it... I've been thinking about extending BeanUtils to understand my ObjectID class, java.util.Date, etc. On Friday, May 30, 2003, at 02:04 PM, Jordan Reed wrote: I've been playing #3 (Just included the value objects in the form) and run into one of those things that probably makes people break into tears.

Have a view helper copy information from the value object into the form (for pre-population) 2) Have the form implement a value-object-like interface. The business layer accepts objects with these business interfaces. This way it is possible to pass the form objects to the business layer without the business layer knowing that they are presentation objects. 3) Have the form simply include value objects as properties. Then use the nested taglibs to populate the value objects. This way the Action can just pull the value object off directly and pass to the business layer.
