[struts faces] How do i set default values?
Hello,
i am trying to convert some struts form to be JSf compatible using
struts faces. However, there are a few problems with initialization for
form.
I have this:
html:form action=/search.do acceptCharset=UTF-8 styleClass=search
html:hidden property=scope value=${param.searchScope}/
html:hidden property=requestedNodeResults value=15/
According to struts faces docs, i need to use the corresponding JSF tag:
h:inputHidden id=scope value=#{myForm.scope}/
h:inputHidden id=requestedNodeResultas
value=#{myForm.requestedNodeResults}/
However, you all can guess my problem, where do i put the 2 default
values for form: '${param.searchScope}' and '15'
According to myfaces mailing list, i should do this in the managed bean
definition. However, there is no managed bean definition in struts faces.
Any suggestion? What am trying to do is incorporate existing struts
forms inside a JSF page. We would like to avoind a immediate complete
rewrite and have a temporary migration solution...

Re: Creating new Session without invalidating the old one
It's tricky to force a new session, and most of time depend on the container.

Re: Struts Action + Multiple Request
RODRIGUES DE ALMEIDA Thiago wrote: Hi All, I have this scenario: In my application, the user has the possibility of openning multiple windows (browser) simutaneously. In this case, each new window makes requests for data thru a struts action. That means, one user can make multiple requests to the servlet container (Tomcat 5.5) at the same time. No problem there, this is made for it and, unless you use something else than request scope bean for your struts action, it shouldn't be a problem for struts too. The problem i have is concerning the performance. Since the user has oppened more than 4 windows, the browser (IE 6) becomes freezed. I have taken a look into the server and apparently there are no problems of memory or processor. For the Tomcat side, i did not see any disturbing problem concerning performance. What would you recommend as solutions for this kind of scenario ? Dump the Threads of your jvm, you might simply be in a deadlock with your application.

[Shale] some questions regarding dialogs and subdialogs
Hello all,
Recently, i decided to play a bit with shale. I began to write some
tests jsp to play with it. I came across various problems/interrogations:
1) considering the following dialog configuration, and the following
jsps (see bottom of email), i am supposed to have one main dialog, with
a button starting a subdialog to edit one specific value.
More precisely, the backing bean of main dialog is a property bean
which gets modified by the subdialog. I can start the dialog ok with
h:commandLink value=start... action=dialog:Test Dialog/, i enter
the subdialog when i click the appropriate button in testMain.faces but
i am stuck in the subdialog. I never return from it. Did i miss
something in the way a dialog is supposed to end? There is no message in
console to help and in subdialog i click on an action which's outcome
should direct to and exit ... of subdialog.
2) I plan in an app to have the following structure:
- have a 'main' dialog present some forms to the user to edit a bean X
containing some properties.
- amongst properties of X there is a collection of element Y, those
elements are complex beans which will be presented read-only
- i need, next to those elements Y to put a button starting a subdialog
for edition of Y.
- How do i pass the element Y as a parameter to the subdialog for edition?
- Will the content of my main dialog be preserved during the run of
subdialog?
3) While testing, i noticed if i start dialog A by clicking on an action
'dialog:A', enter a subdialog B, redeploy the webapp, click again on
action 'dialog:A', i get exceptions in console telling me You have
requested a transition outcome named dialog:A from a state named
in a dialog named B, but no transition definition can be
found. Double check the spelling of the transition outcome name. To
circumvent this problem i need to remove my jsessionId cookie, reload
the page containg the link to action, and the i can start dialog:A. Why
isn't dialog: always assumed as an attempt to start a new dialog and
drop currently running one?
4) is there a way to start a dialog process or create a link to a JSF
page without ressorting to a h:formh:commandLink... construction?
(like http://?action=dialog: or
http:///userDetails.faces?username=), all this to prevent the
use of javascript when possible and allow the sending of direct link to
some JSF content by email.
Greetings,
David Delbecq

Did you do input type=button .. value=bean:message key='blabla'/ which make sense in a JSP, or did you do html:button .. value=bean:message key='blabla'/ which is a non sense as a you can't put a jsp tag inside a parameter of a jsp tag. if you use html:button, use this way html:button ..bean:message key='blabla'/html:button Fredrik Andersson wrote: Hi all I'm still implementing the i18n internationalization on the page and now I have noticed that my buttons don't behave as expected.

Re: Fwd: [OT] How to specify classpath for an application
It's rather not possible in general, The .war is supposed to be a 'complete' application, config included. If you load the ressources using the classloader, you can still use 'tricks' that depend on container specific behaviour, but that is not recommanded. The best way if you want your user not to have to play thmeself with .war content is to provide a ant script that will take a config/ directory and inject it in the .war, so the user easily regenerate the war avec config change.

Re: Extracting MessageResources from Struts
Using message ressources is not struts specific. What struts does beside using message ressources is maintaining the user language in user http session and use it when it need a message ressouce use. If all you need to do is have multi language support for your messages, i suggest you take a look at how ressource bundles are used for i18n in the sun java documentations http://java.sun.com/docs/books/tutorial/i18n/index.html Please note basically the MessageResources is a front end to this allowing configuration of ressources in struts xml configuration file.

It's like this: I have my own framework for creating dynamic SVGs and in one Class I have tooltip-messages hardcoded in German. I don't want to destroy the structure of the method-calls and so I thought about Struts MessageResources where I can use different language packages in form of property files. So far so good, but I don't want to add the whole struts to my framework but just the MessageRessources-part and so my question is: can I just extract the MessageResources.class or is there substitution I can use for this? thanks very much in advance Julian - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

As an example, we have a web application here which can output a full server history. This is about a 10M html file with lots of table. IE took about 30 minute render it, moz about 3 minutes.

Re: struts security
Am sorry but that's not how form based authentification works in j2ee.
We you are not authenticated, the container redirects your to
form-login-page
This page must contain a form with 2 fields : j_username and
j_password. The form action MUST be of type POST and the target MUST be
j_security_check (this is a special url that will be handled by
container, you can not map any servlet there).
example:
form method=POST action=j_security_check
table
tr
tdLogin :/td
tdinput type=text name=j_username/td
/tr
tr
tdMot de passe :/td
tdinput type=password name=j_password/td
/tr
tr
tdinput type=submit value=Entrer !/td
tdinput type=reset value=Annuler/td
/tr
/table
/form
if you use any action other than j_security_check, this will be handled
like any other url query, and no authentification will take place.
The reason you are having father - login form - father apparently
working, is simply because struts does a forward after action, which
take place internally and so is not concerned about the security
constraints.

request.getUserPrincipal() returns a non-null value

Not really. Once user has been authenticated it's written in his
session. Some people have had success by clearing the user session, but
this behaviour is container dependent as, unfortunatly, j2ee specs did
not provide for such a mechanism.

Re: bean:write will not recognize \n or \t
Krishna, Mattam (M.) a écrit : I have the following code in jsp. html:textarea name=empOtherDevFocusBO cols=512 rows=3 property=focusText / Here I am enterd the following text: Test Test. Note:I typed Test and then enter key then tab then Test. After I submit the html:form , it stores the value perfectly in DB. After when I tried to display that value by using bean:write it won't recognize the \n and \t. bean:write output the specified property value in the jspwriter. Not less, not more. If your property has a linefeed and a tab, they will be outputed to jspwriter. Simply it display the value as follows: Test Test Which is the correct display for Test Test in a browser. (linefeed and tab are space separatator.

Re: File download
If i remember well there are special http header that can be used to tell client the response is split in several part. This is mainly used when you send a partial response to client (like a html with table containing 3 rows) and after process advanced you send a more complete response (like the same html but with table containing 10 rows) and so on. You could try a 'file then redirect' construction. That may be worth investigations. See HTTP rfc for informations.

If the user chooses to save the file, then on the successful completion of the file download i need to update a status in the database. After the status is updated the page from which the Save As dialog box was invoked has to be refreshed with the new status. When i invoke a dialog box i use ServletOutputStream and context-disposition to bring up the dialog box. At the end when i write to the servlet output stream the response is commited.

Re: query parameters
Encoding and decoding of query parameters is the job of container (tomcat, jboss, websphere, what ever you are using). The only struts related exception is for multipart/form-data (used for file uploads). There it's common-fileupload library which does the decoding. Why would you want to do the decoding yourself? The decoding/encoding process is done according to rfc1630 specifications. Madhav Bhargava a écrit : Hi All, It is a common practice to encode special characters such as ' ', %, #, :, $ etc.. when sending parameters in the query string along with the URL. We have a similar requirement. Some of the query parameters can contain special characters and therefore we went for UTf-8 encoding. Before using the encoded parameters we call request.getParameter() in the struts action class, decode these parameters and then do any further processing. The problem comes when % is a part of the parameter value. For instance the drugName parameter contains a value *pan% jon%. *This gets encoded into *pan%25+jon%25*. The problem comes when we say request.getParameter() in the action class. The value we get is already decoded to *pan% jon%. *So now when we run the decoder it throws an exception. *How do i stop the automatic decoding of query parameters and do decoding of all the query parameters explicitely? * Madhav -- When I tell the truth, it is not for the sake of convincing those who do not know it, but for the sake of defending those that do - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: How to inject code between HEAD /HEAD of a generated page ?
The JSP writer writes http response, not html response. You can use jsp to generate html, txt, xml, whatever you want. jsp tags are supposed to output content where they are. If you need to autogenerate the head section while you are already in the middle of your .jsp, then you will need your taglib to act hand in hands with a requestfilter which will cache response and inject the head at the end.

Is struts handling informations differently between post and get?
Hello dear members, We created a seach form using struts. The form uses ISO-8859-1 encoding. When posting a query with accentuaed characters, no problems. The browser posts this: scope=%2FfilesrequestedNodeResults=15uri=xsl=query=pr%E9cipitationsx=0y=0 notice the %E9 in parameters, which corresponds to 'é' character in iso-8859-1 Struts handles it without problem, showing the query parameter on screen also works perfectly. However, if i take this query and issues search.do?scope=%2FfilesrequestedNodeResults=15uri=xsl=query=pr%E9cipitationsx=0y=0 It all goes wrong, struts decode the %E9 as an interrogation point! In both cases (POST and GET) the browser does not send a content-encoding to server (so server has to guess what content encoding is used) Also, post is not a multipart So questions are 1) is it expected behaviour that struts behave differently on POST and GET methods regarding the encoding? 2) how to fix it? (i tried switching to utf-8 for query, it got even worse as post also don't work anymore then) -- David Delbecq Royal Meteorological Institute of Belgium - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: data in session affecting performance ?
Hello, I think i read (probably on tomcat mailing list), that clustering should ensure (in specs) that a session is not spread across cluster (once session is started, user always speak with same jvm which started the session).

Hi Amleto,

my web.xml declaration is as follow.

/taglib
More over fact it's Interger not int shouldn't matter, as i said,
another webapp

converted in EL expression
by a equals() call.

Hi,
Which version of JSP+JSTL (and Tomcat) are you using?
I am not sure but I think that the problem is due to fact that 1 is
considered as an Integer class.
This is possible, i suppose, in two cases:
- you are using JSP1.2+JSTL1.0
- or in the taglib directive you are using
http://java.sun.com/jstl/core; and not
http://java.sun.com/jsp/jstl/core; also in JSP2.0+JSTL1.1.
In http://java.sun.com/jstl/core; you use the core1.0 and the
expression language (EL) is evaluated by JSTL and not by JSP, so 1 is
considered Integer (in this case in Java new Integer(1)==new Integer(1)
is false).
In the http://java.sun.com/jsp/jstl/core; case the EL is evaluated by
JSP and the 1 is considered int.
I hope this is useful

!DOCTYPE web-app

Re: passing JavaBeans through an ActionForm?
Koen Jans a écrit : Here's my problem; A user has several accounts, represented by AccountBean objects, all having a unique accountId. Now, i have a form where the user can select one of his accounts to edit through a radio button selection. For the associated ActionForm, i see two options to represent the selected account; 1) on my ActionForm; a property int selectedAccountId 2) on my ActionForm; a property AccountBean selectedAccount The first option seems good because it preserves the philosophy that an ActionForm represents the user's input.. The second is nice because the edit-Action, associated with the form, can immediately extract the selectedAccount from the ActionForm, whereas using the first approach, a database call is needed to retrieve the selected account again by the account's id. Which option would you prefer, and especially why? Thanks for your time - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] The second option may have some problems imho. Every setter in AccountBean is potentially accessible from the user's point of view using http://host/webapp/accountAction.do?XXX=12345 where there is a setXXX() on bean. If your bean is just there to represent some informations (that is every call to setXXX is legitimate for user having rights to the .do action) there is no problem with it. But if your bean is, for example, to be persisted as is in a database, this might be dangerous. What happen if a clerk presented an editAccountPersonalInformations from does use this immediate access to call via struts setAccountCredit() ? Now, i have used your second option quite often, on places where i didn't mind access rights. Now a good way to prevent illegal access to methods is to use the AccountBean private inside form and provide public delegate call to legitimate methods :) regards - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Custom data-type classes, howto
Sorry I was not clear.
Am not asking how to display it in the JSP. This part is quite
straightforward.
What am wondering is how does struts manage the submission of form by user.
If I take the simple example where parameter[0] is to be holder a String and
parameter[1] to be the holder of a Person.
I assume generate this kind of form as result of jsp
form (details on submission here)
input type=hidden name=parameter[0].type value=java.lang.String/
input type=text name=parameter[0].value value=default content 0/
input type=hidden name=parameter[1].type
value=com.mycompany.beans.Person/
input type=text name=parameter[1].value.firstname value=default
firstname/
input type=text name=parameter[1].value.lastname value=default
lastname/
/form
I was thinking to have a form with an array of VariableParameter.
VariableParameter is a custome bean which have 2 properties.
One String for type and one 'Object' for the value.
Perhaps having value as a DynaBean which is then converted to
real type when type is known.
I know there are converter thingies in beanutils used by struts.
Am just wondering if there is an easy way to manage the final convertion
(probably during the validate step if struts is unable to handle it by
itself)
from a DynaBean to SomeCustomClass
thanks
Murray Collingwood a écrit :
On reading this I initially thought you had an array of objects where each
object was a
group of objects such as a file, an int, a string etc. Then I wondered
whether your array
of objects was just that, the first object a file, the second object an int,
the third object a
string etc. Obviously this is more complicated. It sounds as though you are
asking if
Struts has some sort of reflectionyes!
It's called custom tag libraries.
Pass the object to a custom tag library and deal with it appropriately.
When you pass the object it will be just that, an object, unless you also pass
the type,
for example:
Object object;
String objectType;
mylib:display obj=${attributeName.property1}
objType=${attributeName.property2}/

Re: [Hibernate] This stuff is cool
First, Hibernate Mailing List might be a better list to answer your questions.
However, i'll try to answer as am also an Hibernate user.
Le Mardi 20 Septembre 2005 06:30, Murray Collingwood a écrit :
Hi all
Hibernate is an excellent tool! I managed to get it running quite quickly,
only a few
small issues to resolve, fortunately the error messages were fairly clear.
I've implemented Hibernate into the beginning of a new Struts app, however my
code
isn't looking like the examples and I'm wondering if I'm putting files in the
wrong places.
Here is the structure I have:
Note, the term Menu here refers to a restaurant menu item.
Form bean MenuForm is stored in com.path.controller.form
Action class is in com.path.controller.action
In this app my form beans reflect closely the database so I am using the same
form
bean classes for the model.
You mean you are persisting the Struts forms in database?
This is dangerous i think. I'll recommend using the delegate design
pattern to prevent user access to some setters of the bean
(eg. Hibernate requires you to have a setOwner on a bean to
populate it from database but you don't want somebody to be
allowed to change the owner by doing someAction.do?owner=SomeFakeOwner)
So better have form do this:
getXXX(){
return theBean.getXXX();
}
and persist theBean :)
This way you have better control on form setters
I created Menu.hbm.xml and tried placing it in com.path.controller.form as
the
Hibernate documentation said to place these 'hbm' files with the pojos. When
I tried to
start the app Hibernate complained that it couldn't find the Menu.hbm.xml
file. So I
moved the file around a bit, finally placing it in the root of the Source
directory, eg
src/Menu.hbm.xml with src/com/path/controller/form/MenuForm.java. The
contents
of my Menu.hbm.xml is as follows:
?xml version=1.0?
!DOCTYPE hibernate-mapping PUBLIC
-//Hibernate/Hibernate Mapping DTD 3.0//EN
http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd;

property name=price type=float/
property name=rating type=int/
property name=dateFrom type=date/
property name=dateTo type=date/
property name=imageid type=int/
/class
/hibernate-mapping
My hibernate.cfg.xml is:
?xml version=1.0 encoding=UTF-8?
!DOCTYPE hibernate-configuration PUBLIC
-//Hibernate/Hibernate Configuration DTD//EN
http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd;
hibernate-configuration

property name=dialectorg.hibernate.dialect.MySQLDialect/property
!-- Drop and re-create the database schema on startup --
property name=hbm2ddl.autocreate/property
!-- Mapping files --
mapping resource=Menu.hbm.xml/
/session-factory
/hibernate-configuration
THE QUESTION IS: My hbm file is not stored next to the pojo and has to
reference it
using the full path. Is this normal? Is there a better way of doing this?
As Hibernate documentation says, put it along the POJO. If Hibernate didn't
find it, it's perhaps
because of your compilation process. Some ide/automated tools like maven only
compile classes
in src/ directory to target/ directory, they do not copy ressources. Try to
create a separate ressources
directory which is copied in target directory as part of compilation process.
For info, here we put our .hbm files in
webapp/WEB-INF/classes/com/company/somePath
because in compilation process, webapp/* is copied in final war :)
With all this, we have our own session factory which is a singleton having this
in constructor:
Configuration configuration = new Configuration();
// ensure that the *.hbm.xml is located in bin/be/rmi/intranet/db
// (where the class is)
for (int i = 0; i persistedClasses.length; i++) {
configuration.addClass(persistedClasses[i]);
}
sessionFactory = configuration.configure().buildSessionFactory();
with
private static Class[] persistedClasses = new Class[] { V4_news.class,
Scpub.class, User.class, Function.class, FunctionBackup.class,
Vacancy.class, TimeKeeper.class, Project.class };

Re: Being Lazy with Hibernate
For lazy initialization to work, at the moment of the lazy initialisation, (that is the moment you request the data) the hibernate session must not be closed.

Re: Could struts be corrupting my byte[]?
Le Lundi 12 Septembre 2005 16:36, Letícia Álvares Barbalho a écrit :
I did what you suggested and changed from byte[] to String, leaving to
conversion to hibernate's level. It did solve the problem, thank you.
But I'm wondering here... I still got a problem with the charset, don't I?
Well if String is correct in form, you don't have charset problems in the struts
part (decoded ok from browser's POST to ActionForm). However, am not sure
struts handle automatic conversion from String to byte[]. When your action
forms is filled,
here is what happens in non-fileupload forms:
- Browser send form field in a specific encoding.
- Servlet container or commons-fileupload decodes submitted datas and convert
them to string parameters
- Struts take all submited parameters and uses the beanutils populate() method
to fill ActionForm
- For each parameter, populate tries to convert the String to the appropriate
Setter parameter using converters
- In the case of a setXXX(byte[]) signature, the ByteArrayConverter is used.
As far as i can see in this converter source, it's purpose is to convert a
string like 58,107,24,89 into byte[] {58,107,24,89}
which is not what you want i think.
Why i suggested you to explicitly specify the charset used in String to byte[]
is because you are storing text in blob on your database,
that means you must have decided when designed the database, which charset you
wanted to use (i assumed utf-8).
You must remain consistent in your various byte[]-String conversion to this
blob field.
I suggested UTF-8, but maybe some other thing might be more suitable for you.
Anyway, once you have decided a charset for your blob, stick with it.

Re: Could struts be corrupting my byte[]?
As far as i read, you are using an html:text field along a form property of
type byte[]
eg: you type Hello World an you want your form to store
byte[] b={72, 101, 108, 108, 111, 32, 87, 111, 114, 108, 100}
If that's the case, i think declaring the field descricao as a byte in your
struts form
is not a good idea. Your should declare it as a String and convert it to byte[]
when you reach the hibernate level. To keep with your example, this mean
a prototype in your form like this:
public String getDescricao();
public void setDescricao(String);
Then you can transfer to cor like this
cor.setDescricao(addCorForm.getDescricao().getBytes(UTF-8));
and you can get back from cor like this:
String s = new String(cor.getDescricao(),UTF-8);
why? Because if you do not specify the character encoding when
you are converting between bytes and String, you use the platform
dependent character encoding, which may leads you in problems if this
platform dependent encoding change (eg. moving you webserver from
windows to unix)
Also someone suggested you check the character encoding of client http request,
as an additional comment on that suggestion, i'll suggest you try to use the
accept-encoding parameter of the form tag.
Hope this helps
Le Lundi 12 Septembre 2005 14:35, Letícia Álvares Barbalho a écrit :
Hello, everyone.
I have an app which uses struts + hibernate. I was having a problem of
corrupted blobs (which are treated by the app as byte[]), and so far I was
blaming hibernate for that. But right now, making a test, I found out that
my data gets corrupted BEFORE even being treated by hibernate. Here's what I
have:
1. A jsp page that gets a String using html:text, property = descricao
2. An action form that has the descricao property as a byte[], together with
its getters and setters
3. An action that takes data from this action form and puts it in my object,
which by the way also has this property as a byte[], with its getters and
setters.
So, what I wanna do is get this String and put in a blob field. Here comes
my action code:
cor.setCor(addCorForm.getCor());
cor.setNome(addCorForm.getNome());
cor.setDescricao(addCorForm.getDescricao());
CorService.getInstance().addCor(cor);
That's basically it: I set the properties and add. The thing is that if I
get the byte[] value of addCorForm.getDescricao() and convert it to a
string, it gives me NULL or a lot of weird characters. That means my data is
getting corrupted right there, before its insertion.
Another proof of it, is that if I insert a line in this table using the
database's tool, I can retrieve the information through my application.
So... database tool = correct data. App = incorrect data, even before adding
the object in the DB with hibernate. What I can think here is struts is
corrupting... could it be?
1. Is html:text the correct component I have to use for this?
2. Do I have to make any conversion, being that I insert a String and it
gets a byte[]?
How do you guys do it? Thank you all very much for the help

enctype=multipart/form-data. Can Struts handle file upload in another way
when the enctype has not been specified.
not that i know about (struts uses jakarta http fileupload library, supporting
only multipart/form-date for files)
and am not sure another method has been defined by w3c.
(2)
script
function validateDelete()
{
return confirm(Delete Data);
}
/script
html:link action=deleteData name=deleteDataParams scope=page
onclick=return validateDelete()
Delete Data
/html:link
To the validateDelete() Javascript function, I want to pass a java
variable. How do I do it?
Once I pass the variable, my javascript function has to be :
script
function validateDelete(data)
{
return confirm(Delete Data+data);
}
/script
Have you tried this?
html:link action=deleteData name=deleteDataParams scope=page
onclick=return validateDelete('${someBean.someValue}')
Delete Data
/html:link
