Re: .do mappings not working bean cannot be read by the JSP
Iraklis,
I will try to help you, but maybe I could not, because, I am almost in the
start stage as you are. The first you need to understand HOW struts-example
works, you can find "A Walk tour .." in the example menu. This tour explains
step by step, what involve and how in struts-example. The second COMPARE your
struts-config.xml and the example. How the example is starting - from
welcome-file-list file, that is index.jsp. And index.jsp is calling logon.jsp
for logon.do action. And so on.
My point is this - you cannot call
http://localhost:7001/myapp/listDirectoryContents.do
directly from a browser, it must be through some start file. Where is your
"welcome.jsp"?
Your do not have an application resource file, maybe it is OK. Because you do
not want to check anything.
The second, Action class is called by ActionServlet, if the servlet is found
that this action must to be performed according to ActionForm submitted through
a request.

How are you gentlemen!! Somebody set up me the bomb.
I have installed Struts OK, and I've even run the 'struts-example'
application (which means that Struts is working fine with me otherwise.) I'm
trying to create a small application, but I am having problems.
When I type
http://localhost:7001/myapp/listDirectoryContents.do
in the browser, I get a 'page not found'. If I change 'do' to something else
(such as "foo"), I get a Error 404--Not Found, which means that at least the
'action' servlet is called... I am appending my web.xml and
struts-config.xml: for the life of me I can't spot anything wrong about
them.
A second problem that I've wasted my youth on is that my action class adds
an object (bean, if you wish) to the request or session by the following:
HttpSession session = request.getSession();
session.setAttribute("com.covia.struts.folder_contents", di);
or
request.setAttribute("com.covia.struts.folder_contents", di);
(I'm saying 'or' because I've tried both.)
In my JSP I've used the following line:
logic:iterate id="aFile" name="com.covia.struts.folder_contents"
property="fileroomFolders" scope="session"
...
to access this bean, but I get a message saying
Apr 5, 2001 6:32:56 PM CDT Error HTTP
[WebAppServletContext(2243896,fileroom_struts)] Root cause of
ServletException
javax.servlet.jsp.JspException: Cannot find bean
com.covia.struts.folder_contents in scope session
Again, I've tried this using both 'session' and 'request' scope.
My understanding has been that the action class gets called first. It places
whatever it needs on the request/session, and then the JSP file that's
listed in struts-config.xml as its 'input' runs right afterwards. Did I get
something wrong?
Infinite thanks to whoever can help me with this! I've already wasted a ton
of time - to no avail - trying to solve this.
thanks much,
Iraklis

Re: Newbie question #2
Here is the reply from Craig M. for similar question - John Hunt wrote: 1.What is the normal practice in the case where you have two pages, and part of the input entered in the first page needs to be displayed in the second page. I would say use the same form bean for both the pages. Any objections to this? This would also be the normal approach to a multi-page form -- all of the pages would share the same form bean, whose properties would be all the fields that appear on *any* of the pages. The interesting part of this is knowing what to check in your validate() method, which will be called as each page is submitted. 2. When displaying readonly contents on a page where the contents were obtained by some processing done by the Acton class which forwarded to this page, is it advisable to put the output page's bean in session scope and have the action class populate it ( or even under request scope ). Or is it better to expose many beans from the Action class that produced the data and let the form bean get populated in the jsp page ( for the readonly attributes )? So these attributes actually need not be propagated to the next action class. Suggestions??? I would not generally use the form bean for read only attributes -- instead, I'd just create request or session attributes (depending on how long you wish to keep them) and use bean:write to display the read-only contents of those beans. This works even when you are not inside a form, and you can have any number of beans accessible to bean:write, but only one form bean per form.

Re: form bean question
Eugene, If I have understood your question, the 1st place is jsp file, where the form is directly used. The 2nd place (config file) where you set mapping up. For example you tell that logonForm (the first letter is lower case) is coming from the class LogonForm, and jsp file logon.jsp will be called if the server needs to access the form logonForm. Maya Jacob Thomas wrote: The html:form tag will either lookup or instantiate the ActionForm so that the form parameters can be set to meaningful values on the page. Then, when the user makes changes and submits the form, the ActionServlet will populate the same ActionForm instance (if it is given 'session' scope) with the user's values and pass the form bean to the Action controller. -- Jacob -Original Message- From: Eugene Krivopaltsev [mailto:[EMAIL PROTECTED]] Sent: Thursday, March 29, 2001 10:52 AM To: [EMAIL PROTECTED] Subject: form bean question Hello everyone, I am learning struts and have following question: Why form should be described in two places: 1. in jsp page (I am looking at logon example): html:form name="LogonForm" type="fully qualif. name" ... 2. struts-config.xml form bean name=name="LogonForm" type = " as in 1 " .

Re: Estimating Projects with Struts
It is depending on how much your team are familiar with Struts. If you can explain or draw a good picture for page developers how to use the Struts tags, then to develop small screen - 1/2 day (from a scratch), big one - 1 week. Then your java developers need to make the Action and Form classes for each form (until we do not have a general purpose Action and Form). It can take 2 months, depending how big is your team.

Re: ServletException: org/apache/struts/action/ActionForm
Of course, you have reference to this class if you have compiled your LogonForm class with struts.jar. But one thing is to compile, other thing it is to run. When you run your application Tomcat must to find struts.jar under your_app/WEB-INF/lib. ApplicationMapping class is in your application too, if you are using struts-example as the base. Check it's source code to understand from what mapping is coming. Maya Manuel Alzola wrote: Hello.No reference to ActionForm in all the project.

Re: Locales and images
I am trying to use this for different "look". But my principle is simple. In one application a.gif - is a blank, in other - it is some picture. And so on... Change your property file to point to a different directory for different "look". But in this approach you have one match between application and the property file. If you want to change a "look" on-fly, you need to have different images, for example, a_look1.gif, a_look2.gif and make a different link depending on a "look" parameter.

Re: Locales and images
1/
How about several files under A directory:
B.properties
B_en.properties
B_de.properties
B_fr.properties
and so on...
Can you see it, that you have a problem.
2/
How about a file name as extra init parameter that has names of all properties
files that you want to "combine". But this becomes a little complicated when you
think about different languages.

Anyone have a snippet of a build.xml that's does this "combining" of

I appologize for beating this thread to death, but I want to mention 2
more things.
1) I think I found another way to merge multiple
properties files (if anyone cares :-). I could write my own
MessageResourcesFactory class and pass that in via the "factory"
init-param of my web.xml file. My home-grown class could do something
like merge all properties files found under a directory, and either throw
an exception on duplicates, or simply ignore repeats.
2) Is it possible to change "application" (init-param) to somehow
suck in a HashMap of MessageResources? Maybe through
multiple init-params or a properties file containing pointers to other
properties files. Then I'd call something like getMessage("imagebundle",
"go.away.button", arg1), or perhaps use a static
getMessageResourcesByMap("imagebundle"). Also when using struts
taglibs, when I send - bundle="imagebundle", it would use it as
a key into the HashMap of MessageResources. Does this sound feasable
or even needed?
Looking at the Struts code, it looks like it might be too much to introduce, but
just thought I'd mention it.

Re: reloading issue

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. Maya Ken Beyer wrote: 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.

You are correct about the implications of using multiple application resource bundles -- it's a lot of work, but definitely feasible. 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.

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? Otherwise I'd always get the application's default language. Thx- Ken Maya Muchnik wrote: 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. Maya
nested tags again - Q
Hi, Maybe this question was posted already. I am sorry for the repetition. Can somebody suggest what is the best case to resolve this expression (maybe nested tags are not working): html:hidden property="domainID" value='%= bean:message key="admin.domaindn"/'/ value of domainID is still %= bean:message key="admin.domaindn"/ Thank you all in advance.

I think, you are correct to qualify this as a formatting. Take the struts-example. The tag html:errors/ at the beginning of each file will display error messages at top and left corner of a page.

Re: Performance of struts
I think, it will be slower because you have one central servlet DISPATCHER that is sending a "job" to different Actions. When you have some JSP that are sending "job" themselves to other JSP, it is faster. Is it convenient? I think - no, because a creator JSP does not know java. And change flow, redesign difficult. Now, I have this "pie". Maya Keith wrote: Hi, I am sorry if I offend anyone. I am evaluating struts and notice that the performance is much lower that if I use string jsp and servlets.

Re: How do I really bypass the deficient of a HTM editor?
Hi, Keith, I think, DreamWeaver has an implementation to display custom tags (UltraDev), and now they are working to embed a support for the struts. Can you give example you are talking about? Do you want, that tags will send additional HTML code? Maya Keith wrote: Hi; I am new to struts, and thought I would be great if I can completely separate the HTML and web design from the java code. So, I tried out the first few pages of a project with struts implementation, only to realize that the web designer will not be able to see his design because all the custom tags cannot be displayed. Consequently, I search in the mailing list archive, and notice that many people are having the same problem as I do. I came across a thread in which the author suggested embedding HTML code in the custom tags to enable the web designer to see the placement of the widgets. Everything seems to work except when I tried to use bean:message tag to display labels. Struts complains about not allowing content in this tag. Has anyone have the same problem? How do you let the web designer does his design without having to guess the position of the labels and boxes? Thanks keith

reload configuration and transaction
Hi, If you remember we can use /admin/reload action to reload all configuration files and beans, actions and so on. What happens if some users are doing their transactions in the same time? Is the ActionServlet is checking anything or not? Maybe a user will get an error "Server unavailable" in the middle of a transaction? Maybe "reload" option can be used only in a debug stage?

Re: How to generate a form bean manually?
It is my guess. Take as example logon.jsp and registration.jsp. The first jsp uses a part of info for the second jsp (or form). I think you need to have 2 form beans, one for fill in parameters, other one - for full object. John Chang wrote: Usually, a form bean is automatically created after a user submit the form at the first time. But if I want to generate the form bean before the form is shown, how can I do that? The reason for me to do so is for this case: some information of the form are already in database. When users fill the form, they don't have to input these information. Another question, how can I get the instance of the form bean in my JSP file? Thanks a lot! John Chang __ Do You Yahoo!? Yahoo!

Hello all,
I have an application that contain support for multiple languages, we opt

We now have a problem that during validation, when there is an error, we
would like the page forwarded back to the original jsp (of the originating
language). But right now the mapping only allow us to define one input form,
so upon looking at the source file, I think we can redefine
processValidate() of ActionServlet a bit, instead of getting the input form
from the mapping, we can get it from a parameter:
// Has an input form been specified for this mapping?
String uri = (request.getParameter(Constants.INPUT_FORM));
if (uri == null || uri.equals(""))
{ uri = mapping.getInput(); }
The idea is like this, is our approach correct? (pls don't say we shouldn't
have a duplicate set of jsp) Or there is some better way to achieve that?
Thanks a lot.

Re: Access to ApplicationResources.properties from Action class?
David,
Please clarify for me. I am trying use your application for validation and display
different error depending on a selected language. It is 05 release. Your
RegistrationAction.java or MultiRegistrationAction.java calls
Locale locale = getLocale(request);
but it is not used in the source code (directly). Maybe I am missing something. Your
have 2 properties files depending on the language. Does MessageResources use them?
Thanks,

Hello,
I think that the best thing to do would be to not
use the text of
the button at all. If you use the text you will need
to change the
code as well if you decide to change the text on the
button by
editing the property file. (And if you get
internationalization into
the picture it will be even worse.)
I think the solution would be to have different
names on the
buttons (using the 'property' attribute of the
html:submit tag) and
check the button used by having properties for all
the possible names
in the Form bean and see which property that is
different from null.
(Or by doing a request.getParameter() as you do in
your example, but
I like the automatic way better :-) )
The downside of that is of course that you need
extra properties in the
Form bean class but I still think it will be worth
it.
To come back to the original question I do not know
how to do it
but I guess that it would be possible to find by
checking the source
of the bean:message tag.

Hi all,
I'm pretty new to struts, and just started

I have a (probably) pretty simple question:
I'm in the perform method of the Action class,
processing a form submit, but
want to
forward to different mappings depending on which
button was pressed.
In the JSP I am using the
ApplicationResources.properties file to create the
button text for the
different buttons, so now I need to access this
text also to determine which
action to
take.
So how do I access the descriptions from the
properties file in the Action
class?
my form:
---
tr
td colspan="5" align="right"
html:submit styleClass="bodyform"
bean:message key="button.cancel"/
/html:submitnbsp;/td
td
html:submit styleClass="bodyform"
bean:message key="button.edit"/
/html:submitnbsp;/td
td
html:submit styleClass="bodyform"
bean:message key="button.confirm"/
/html:submit/td
/tr
---
So what do I put at the ... in the following
fragment of the perform()
method to
be able to get the textual value of the
button.cancel and button.edit?
---
String submit = request.getParameter("submit");
// Forward control depending on which button was
pressed
if (submit.equals(...))
return (mapping.findForward("cancel"))
else if (submit.equals(...))
return (mapping.findForward("edit"))

Sorry folks, for this thread, because it does not "concerns" the struts

Nanduri,
You can not consider an offset as a correct reference to time zone. For

+2 hours. They are all in different time zones!

Re: Gratitude
Welcome a "board", John. We are all gratefully happy that we have Struts and its developers / contributors. Maya John Wright wrote: Struts developers and other contributors, I have been working several months on a project and was really getting nowhere. I had implemented my own MVC framework based on some usely assorted ideas mostly from JavaWorld articles. Then I found Struts yesterday. It blew me away. I intuitively knew right away that it was the right architecture and would save me tons of time by allowing me to avoid that tedious JSP programming that was bogging me down. I know letters like this don't help anyone to learn more about Struts but I felt like I have to say thanks. This is one of the best and most well documented frameworks I have ever seen. I dreamt about Struts last night. :) Maybee now I can get back to 8 hour days and time to take a walk in the woods and watch the beautiful spring come in (I am not exaggerating). I will try to repay what I get from Struts by contributing to this list. I am a really fast learner of frameworks. That is at least one of my skills. John Wright Kansas City, MO P.S.

Re: user time-zone
Amar, (I am sorry for a mix up with your last name)
Maybe you are correct. My point is time zone and offset are two different
measures. You cannot calculate a time zone if you know an offset. But you can
calculate the offset if you know the time zone.

Maya,
It all depends on your design and the project you are working on. Let
me give you an example...
If lets say i have locations in different parts of the world and i
want to reserve tickets for those Locations. I already know the timezone the
Location is present (since a location can't change. If a Location changes
then i have no answer and i leave it to the experts to answer that
question). I simply store the offsets with reference to GMT in my database.
If the user selects a particular Location i know the correct offset and
timezone.
Am i making sense ?

Sorry folks, for this thread, because it does not "concerns" the struts
directly (some designing issue).
Nanduri,
You can not consider an offset as a correct reference to time zone. For
example, Cairo - has +2 hours from GMT, Helsinki - the same +2 hours, Israel
-
+2 hours. They are all in different time zones!

Re: ActionForm question (repost)

if this field has to be a number. If validation is OK, put to database
converted data.

Question about creating ActionForm beans --
What kinds of data types are supported? I could not find a reference to
this in the docs. For example, I want to have an input box on my forms,
where the user can enter a number. Or, they can leave it blank. I want
"blank" to show up as null, not zero. Should I implement my ActionForm
bean as follows?
Integer qty;
Integer getQty() { return qty; }
void setQty(Integer) { this.qty = qty; }
I've chosen Integer because it can hold a value, OR it can be null
(which is the behavior I'm looking for).
Will this work, or must I restrict my data types to Strings and do
conversion somewhere else?

Re: Is the struts example itself is multi-thread safe?
Thank you, Craig for clear "picture". One Q. to be sure that all OK. What about servlet.log file? Several action threads will need to have an access to it.,... Maya "Craig R. McClanahan" wrote: Maya Muchnik wrote: Hi, In "A Walking Tour of the Struts App", the author has mentioned that "There is only one object for each action (URI), so your action objects must be multi-thread safe". Is the example itself is multi-thread safe? I am asking this, because are several actions here, but not one of them use "synchronized" statement. Maybe I am missing something... Possibly. Thread-safety is a general term meaning "even if two or more users are calling methods in my class *simultaneously*, nothing will get messed up. In the case of Action classes in the example application, they are indeed thread safe. Why? Primarily because they use no instance variables -- only local variables within the perform() method. If the example used instance variables, then there would be only one copy of those variables (because Struts creates only one instance of your Action). However, local variables appear on the stack for each request thread that is happening simultaneously. Any single thread can only see its own copy of these variables, so there is no possibility for contention. One place you will see synchronization in the example app is when adding to the pseudo-database. Consider what would happen if two users logged on with the same id, and both proceeded to add a new subscription at exactly the same moment. You would have two attempts to modify the database (which, because it is a servlet context attribute, is visible to all request processing threads), so you need to synchronize here. The other place that you commonly need to synchronize is when you are modifying session attributes (read-only access is generally safe without locking). It is surprisingly easy to have multiple requests active at the same time for the same session -- for example: * In a framed presentation, the browser will often issue requests for more than one frame at the same time, all with the same session id. * Users might open multiple browser windows, which (in many circumstances) causes each window to be part of the same session. * The user can submit a long running transaction, press STOP (which the server does not know about), and then start something else.
