struts tags
Hi, Can anybody help me as soon as possible with the following questions : 1. Readonly text field : How do I create a readonly input text form field, using the struts tag "html:text" ? A standard html tag can have the readonly attribute set, but this does not seem to exist for the corresponding struts tag "html:text". 2. Populating beans : Using struts html tags, a form field is coupled to a bean property. When only "property" is specified, the field is coupled to a property of the corresponding form bean. When "name" and "property" are specified, the field can be coupled to a property of another bean. However, when the form is submitted, the form field value will only be put automatically into the corresponding property in case of using a form bean. In case of using another bean than a form bean, the property is not set automatically (I have to populate this other bean myself). That means that the coupling of form fields to other beans than form beans only works in the get-direction (properties are consulted for rendering the form fields), not in the set-direction. Why this asymmetrical behaviour ? 3. Sometimes I need form fields with a name, to be used by JavaScript, but without coupling them to a bean property. Hence I created form fields with a "property" specified, which does not exist in the form bean. I would expect that this should work, not setting any (non existent) property in the form bean. But I get : javax.servlet.ServletException: runtime failure in custom tag 'form' H. Franken, software engineer at Agfa n.v.

Re: reloading issue
Additional info: if you recompile FormBean, Action, then copy a new *class file under appropriate tomcat directory. It will be reloaded automatically (if you do not change Tomcat configuration).

Re: Locales and images
I'm struggling with something very similar and could really use a recommendation. In the Building View Components documentation about i18n, (http://jakarta.apache.org/struts/userGuide/building_view.html), it describes using a MyResources.properties (default) and other MyResources_XX.properties for other languages. This uses the "application" init-param of the ActionServlet in web.xml. That's fine and dandy for a small application, but for a large JSP application, I don't think I want to maintain *all* my i18n text (including images!) in a single file per language. I'm thinking the best way to break this up is to put some "common" text in a file like CommonResources.properties. Put my images in a file like ImageResources.properties. And finally put text that is unique to each JSP file in their own properties files (for example Foo.jsp -> FooResources.properties, Bar.jsp -> BarResources.properties, etc.) - and I realize that for each language, I'd need a BarResources_DE.properties for example, but that's okay. I think that each of these ResourceBundle's needs to be put under their own application scoped bean/key, i.e. imageresource -> com.mycompany.mypackage.ImageResources. Question is, is this the right approach? If so, how do I do this? I think I use ... bundle="fooresource" via each struts tag, (i.e. ) And I'd have to load that in advance via each controller servlet (or should I extend org.apache.struts.action.ActionServlet and load them all there). Is this all correct? A pointer to an example would help me greatly.

Re: Any good example?
struts-example is the best known open example how to use struts. If you know it with all details - you are in good "shape". Any form extends ActionForm. When you will design your application you will start with forms design, beans corresponding to them and so on...

Re: strange html:form tag
Then struts html:form tag is processed if the action name does not have a .do at the end, one will be appended so when it is sent out to the browser it will always see a 'XXX.do' present.

Re: Locales and images
To have a separate property file for each JSP - it is too much. All the rest - a good idea. I am creating my servlet that extends ActionServlet and does two things: expending destroy and init functions. The reason - I have to initialize some paramaters that I will use in xxxAction through application attributes. Other thing you need to remember that all xxx_xx.properties files do not need to have all messages that in the xxx.properties file. Only what is different.

Then, Tomcat will reload your application when any class that is in WEB-INF/classes is changed. Note that Tomcat 3.2 has some inconsistencies in this regard, and does not always detect changes to bean classes. Tomcat 4.0 cures this deficiency. In addition, Struts offers a standard action that tells Struts to reload its configuration files (see the entry in the example application). However, this by itself will not deal with changed Java classes -- the servlet container has to take care of that for you. Craig

You still need to set up your in web.xml, the same as
you did before.
THe difference is that the Struts controller servlet reads the web.xml
file itself at startup time, and remembers which mapping you have
selected. If you do the usual extension mapping ("*.do"), it will
generate a hyperlink to "/saveRegistration.do"). Likewise, if you use
path mapping instead (say, "/execute/*"), the same tag would
generate a hyperlink to "/execute/saveRegistration".

Perhaps, for example, you've created image buttons and the text of those buttons needs to be different depending on the user's locale. Now, let's take Maya's example, and say that our images are stored in an "images" directory (relative to the context path of this application). Now, in my application resources for English, I might have: image.a=/images/a_en.gif image.b=/images/b.gif while in my application resources for French, I might have: image.a=/images.a_fr.gif image.b=/images.b.gif Note that -- with these settings -- I'm using a different GIF file for the "a" image, but (currently) sharing the "b" image. Now, I can create a single JSP page that grabs the correct version of each image: (When you use the "pageKey" attribute, your paths have to be context relative and start with a slash, just like all the paths in struts-config.xml.) Note one added advantage of this approach. Currently, we're sharing the "b" image because it didn't need to be internationalized. Now, you decide that you really do want to make it different. All you have to do is: * Create the new "/images/b_en.gif" and "/images/b_fr.gif" image files * Change the two lines in your application resources * Restart your app, with no change to any JSP page that uses those images.

One alternative strategy to consider is to keep the application resource bundles separate in your *source* code, but combine them together when you deploy the application (for example, you can use the unix "cat" command or the DOS "copy" command to combine text files). As long as the message keys are all unique (which you should manage by requiring specific prefixes for different portions of the app), this will still work fine. The same basic strategy can be used to allow different developers to work on their own portions of the "struts-config.xml" file in the source code, but combine them all together when you create the application itself. > Thanks, > Ken > > Craig

I'm also seeing that it's way too much now (a message resource per jsp). I found the following to be helpful... http://jakarta.apache.org/struts/api/org/apache/struts/util/package-summary.html#doc.Messages I'm thinking of at least starting off with separating the images from text, and maybe breaking the text down into packages later on. Is it correct that I should override ActionServlet, and pass in additional init-param's similar to the "application" one?, i.e. imageresource com.mycompany.mypkg.ImageResources and then make sure that I load it (by overriding init()) and calling a private void initImageResources() + super init(), and similarly for the destroy. Also, I need to set locale to true in the web.xml (Action servlet section), and make sure I use "getMessage(Locale, String, ...)" pretty faithfully, right?

Craig, As I understand Ken, he wants to have several files and not combine them in a application level. He wants to add one attribute for each tag, where the file name is pointed out. Right Ken?

OK, so let me see if I understand what you are saying: the tag will trigger FormTag.doStartTag(), which will append ".do" if no extension was specified.

That looks like a problem that occurs with several servlet containers.
JSP compilers are required to perform conversions between the String
version of custom tag attribute values and the corresponding data type of
the underlying property (boolean in this case). This requirement was not
clear in the JSP 1.1 spec, but was clarified in an errata published last
April, available at:
http://java.sun.com/products/jsp/download.html
This should probably be reported as a bug to Sybase.

more on ActionForms
Struts appears to be ignoring the ActionForms that I am trying to manually put in the session. If the ActionForm is not the same class type as what is defined in struts-config.xml then Struts ignores it and creates a new one when the page is processed. Is this the intended behavior? If so, I would like to propose a slight change to the logic Struts uses when creating an instance of an action form. Currently, as I understand it, Struts will check to see if an instance of the ActionForm exists in the session based on the name assigned to the attribute and the class type of the attribute. If either do not match, then Struts creates a new ActionForm of the type defined in the mapping. What about changing this so that the object in the session can be of the same type, *or* a subclass of the class specified in the struts-config.xml? Can anyone think of a scenario where this would cause problems? I am having problems with the design of my application because of this. If this functionality was supported things would become simpler and the app would be more extensible. Comments? -Bob -Original Message- From: Hayden,Robert IT BIP-US-R Sent: Tuesday, March 20, 2001 1:09 AM To: [EMAIL PROTECTED] Subject: Object oriented question regarding ActionForms I have an object oriented question related to how Struts instantiates an ActionForm. What I am trying to do is utilize a factory for creation of my ActionForms. In my application, I have a base (abstract) ActionForm class called Fermentation, and subclasses FermentationYeast, FermentationEcoli, etc... The factory is called from my Action servlet to create the appropriate instance of an ActionForm (a subtype of Fermentation). Then I save the newly created ActionForm in the session. The object type that gets saved in the session is the subtype, but in my Struts config I am specifying the base type. I want Struts to read this object from the session, but Struts always creates a new ActionForm of the base type. I want it to find and use the subtype! For example, the Action servlet calls the factory and the factory returns a FermentationYeast. This object is saved in the session, and then I forward to the EditFermentation page. The EditFermentation page is mapped in the Struts config to use a Fermentation form, so Struts does not recognize the FermentationYeast that is already in the session and it creates a new ActionForm. Even though a FermentationYeast *is a* Fermentation, Struts does not seem to support this. I think it would be helpful if Struts supported generalization... or if it does and I am missing something here please let me know :) Or, If you think I should change my design, please let me know this as well. I think I have a good reason to need to do this. The first page is where the user enters common information, then the next page is loaded based on the type of the Fermentation (ActionFrom). I could create 2 separate ActionForms (one for the common attributes and then another for the details) but I would like to use inheritance to model this relationship. In other words, I want to create a single ActionForm which will be used across multiple pages, but I want to share pages that ask for the same information. Thanks, Bob

Re: HELP - "Illegal target of jump or branch"
I am, unfortunately, intimately familiar with this problem. The problem is that there is a limit on the size of a compiled method in a Java class file, and that limit is what we're running up against. Recall that a JSP page is compiled into a servlet, and into essentially only one method in that servlet. Hence, if your page contains many, many tags, that method becomes too big, and up comes the exception that you're seeing. There are a couple of (partial) solutions. 1) Break your giant page up into multiple smaller pages and bring them together at run time using . Note that <%@include> won't work, because that's a compile-time include, which will get you straight back to the original problem. 2) Look for places to save on tags. For example, the tag was recently extended to allow the specification of the text to display, so that you can replace this: with this: If you have a lot of cases of this pattern, it can help quite a bit. In addition to the tag, some other Struts tags allow the same shortcut to including the text. Also, you might consider replacing sequences with if you can build an appropriate collection up front. Unfortunately, we can't use solution (1), because our giant page is almost entirely one . (Please don't ask... :-} ) Many of the tags won't work if they are on a separate page from the tag itself. That means I've spent quite some time on option (2). We have several of our own tags, too, so that was the next place for me to look. I discovered that changing some frequently used tags from extending BodyTagSupport to extending TagSupport, and marking them with empty in the .tld file, made a significant reduction in generated code size. Of course, this is not always feasible, but it helped us quite a bit. One other trick is to create custom tags for frequently used groups of related elements. For example, I created a simple DatePickerTag which is a Struts-like tag that combines three drop-down boxes for month, day and year, with the localized strings obtained from the JVM, and the current values pulled from a bean. That's about all I can think of that I've tried so far. All our pages are now within the limit, but one is very close to breaking it. I really want to put a "do not touch" notice on that file! Hope this helps. -- Martin Cooper At 12:06 PM 3/20/01, Marc Ellison wrote: >Hi, > >I have been getting a very interesting error folks ;-) > >I have constructed a jsp file that uses ALOT of struts-defined tags, and >which I have running with Tomcat.

Re: Locales and images

Can't access ActionForm properties in Action perform()!
Hi, There: I have some question regarding access the actionform, I have two Actions, one is "edit" and one is "save", they both share the same form just like struts-example, when I do the edit, the form is access fun, but when I do the save, the ActionForm is not null, but content in form is null, I am really no sure is the scope problem or something else. If anybody have similar problem before, please give some help. Thanks in advance. Regards Frank Ling

the errors tag
Hi,
Am trying out the errors tag but to no avail...I have the following code in
my validate() method of my relevant Form class...
public ActionErrors validate(ActionMapping mapping, HttpServletRequest
request) {
ActionErrors errors = new ActionErrors();
//if (phn == null)
errors.add("phn", new ActionError("phn can't be null"));
}
...and then have the tag in my jsp. However when I process
the request having left the "phn" field empty, nothing pops up on my jsp
page. Am i missing something vital here. I have followed the docs and API to
no avail!
Thanks

Multipart problems
(I originally posted this to struts-dev, but since I'm really looking for confirmation of these problems from other users, I guess I should post it here.) I've been having a host of problems associated with multipart input: (1) cancel detection fails and must be special-cased; (2) transaction token checking fails and must be special-cased; (3) parameters that are ordinarily available via request.getParameter() must be accessed via an ActionForm; (4) forwards from pages that use multipart input fail unless redirect=true. If anyone can tell me what I'm doing wrong, I'll be grateful. Alternatively, if some or all of these are genuine problems, I'll be glad to supply more details and file bug reports or enhancement requests as appropriate. Thanks. -r

Which? IPlanet Application server or IPlanet web server with Struts
Hi, I am forced to use IPlanet for putting my application into production. I am wondering if I could use just IPlanet Web Server (IWS) for my application using Struts instead of having to use IPlanet application server(IAS). My application consists of JSPs, Servlets and Java Beans( and no EJBs). Do I need an application server in such a scenerio or would a web server be sufficient? I would really appreciate responses from anyone who has successfully used IPlanet products with Struts. Thanks. -Nimmi
New to struts..
I'm new to struts and started using it (just deployed the struts-example). I wonder whether we could use struts out of the Web Application Archive, as an extracted one, without any reference to web.xml and just refer only the tld and struts.jar file. Are there any sample or simple application demonstrating the above.

RE: the errors tag
I'm not sure. Here is a quick run down of things.
1. You are extending ActionForm.
2. The interface to you're validate method looks fine.
3. Validate is set to true in the action in the
struts-config.xml.
4. You correctly have the ActionForm associated with
the correct action in the struts-config.xml.
5. You are submitting to the correct action.
I would put a println or log a message from your
validate method and see if it is actually being
called. If the validate is set to true in the xml
configuration, then it will call the validate method
and put the object in scope for to use.
If the validate method isn't being called, make sure
that the form-bean name attribute matches the action
name (case sensitive).
I assume you are using a recent build of Struts.

Re: the errors tag
The constructor for ActionError takes the key for the error message, not
the error message itself. This key is then used to look up the (possibly
localized) message in a message resource.
If the key is not found, by default null will be returned, and nothing will
be displayed. This is most likely why you are not seeing anything. However,
you can set a servlet init param to change this behaviour. Adding this to
your web.xml:
null
false
will cause the string "???key???" (where key is the key name you supplied)
to be returned, and subsequently displayed, when the requested resource is
not found.
Hope this helps.

Forms Engine?
Hi, I am in the process of building an application with a large number of screens. Each of these screens will conform to one of a small number of pre-defined templates / classes. What I am looking to do is find a tool and/or design that allows sort of a "parameterized form" to be built at run-time. The form would be built by combining the appropriate JSP template with the form definition. This saves us the hassle of stamping several hundred very similar pages, ensures consistency, and reduces errors. Has anyone tried doing this with Struts? Thanks, Anthony __ Do You Yahoo!?

Mouseover effects on links

db and forms
Hello, If I may I would like to inquire about db/form handling using Struts framework in theoretical point of view. For instance I have 2 tables in my db, let's say "Customers": CustomerID int, Name varchar, Password varchar and "Phones": PhoneIDint, CustomerID int, Number varchar A customer can log on to a web site by specifying his Name and Password on the index page and after that he gets to a main page where he can choose between three links: "view/edit personal information", "view/edit phones" and "add phone". I (almost) understand how to organize logon process: I create a LogonForm.java that represents form elements on the index page and LogonAction.java where I get values from the form and use them to query db to find out if there is such a user and if so I put UserID taken from ResultSet into session and finally load the main page. As I mentioned the main page contains three links which, as I guess, should point to Action Forms, something like "editCustomer.do?Action=Edit", "editPhone.do?Action=Edit" and "editPhone.do?Action=Create". Also I should have jsp pages for creating/editing(viewing) customer and phone information (customer.jsp, phones.jsp (for list of phones) and phone.jsp (for particular phone)). And this is where my poor understanding of overall process ends. What should happen when anyone clicks "editCustomer.do?Action=Edit"? As far as I know I have to create java files like this "CustomerForm.java" and "CustomerAction.java" and perhaps "SaveCustomerAction.java". CustomerForm.java encapsulates data and methods of the form (setter, getter), CustomerAction.java is used to fill in that form (how?) and SaveCustomerAction.java to get data from the form and save them into db, right? Then CustomerAction.java and SaveCustomerAction.java have to contain db related java code where I make use a session element that contains value of CustomerID, right? And what if I need to show some page information of which is based on many ID (parameters)? Should I pass them through URL or Struts offers another way? Well the more I writing the more questions I have and I suppose nobody has time to answer them, but perhaps someone could share couple of his jsp/java files (along with struts-config.xml) that deal with relation db and forms similar to those I tried to describe above. Struts-example it's a good thing but more examples are even better. I would really appreciate any help. Thank you for your time. Best of luck. ___ Do You Yahoo!?

Struts, Trubine, Velocity, Expresso
Hi, I recently explored the Struts Application framework features and developed an small application using Struts. Recently I heard about other frameworks like Trubine, Velocity and Expresso. I am really confused about what to choose and what is the difference between these frameworks. Can anybody explain these frameworks and their differences ? Thanks in advance Muhammed Aamir

It might be.
In order for this to work, Struts has to be able to parse the web
application deployment descriptor (/WEB-INF/web.xml). To do this, Struts
calls:
InputStream is =
getServletContext().getResourceAsStream("/WEB-INF/web.xml");
At various times Orion has returned null from this call, because the
developers incorrectly believed that a servlet should not be able to
access resources in the /WEB-INF directory. This has gone back and forth
in various Orion versions.
Are there any interesting log messages during the startup of the
controller servlet?

Parallel iteration
Hi folks, I have two ArrayLists that are guaranteed to have the same number of elements.
