FAQ (Passing Variables Between Actions); But, Stuck and Need Help
Passing variables from one action to another is a frequently asked question. The answer is to use either hidden fields or a session object. The story starts with searching the database. My application offers options to search the database by author, title of the article, article ID, or . I have a drop-down list in my JSP for visitors to make a selection. By clicking on one of those options, the property dispatch is set. And the visitor fills out the text field to set keyValue. With both dispatch and keyValue forwarded to an action; say, Action ONE, the desired articles can be retrieved from the database. So far so good. What I have handled next is the author's page of the web site. An author can only view his own articles and perform update, delete, save, ... functions. I use the hidden field technique to handle it. The property dispatch is arbitrarily set as author (needless to say) and keyValue can be obtained by String username = request.getRemoteUser(); And, html:hidden property=dispatch value=author/ html:hidden property=keyValue value=%=username%/ are forwarded to the same action (Action ONE) for processing. Again, no problem. Now, the application has another user case - editors. An editor only retrieve and view all articles in his/her own field of specialization. I arbitrarily set dispatch as field_of_specialization and use the hidden field technique: html:hidden property=dispatch value=field_of_Specialization/ Nonetheless, the way to get the value the editor's field of specialization is from the database. Because editors are registered members of the web site, the application should be able to look for his/her profile and obtain his/her field of specialization in the database once an editor successfully logs into the web site. Therefore, it takes an action (Action TWO) that tells the business tier to find the keyValue in the database. And should I put the keyValue in a session object. I have tried to handle this situation again and again in many different ways. I am very frustrated and need help -- how does a user go from by clicking a button in a JSP to go to Action TWO (get the keyValue) and then forward this keyValue and html:hidden property=dispatch value=field_of_Specialization/ to Action ONE for retrieving the desired articles from the database? __ Do you Yahoo!?

It looks like you're not the first to have redirect=true backfire on

try
response.sendRedirect() within your action class and just return

Hi all,
quick question on validation:
Can we setup validator with rules like x must be equal or greater than
8, just to limit the lower bound ?
Currently, i use the range validator, which means i have to specify the
lower and upper bound, right?
Any clues and pointers appreciated.
Thanks.

Secondly, you could drop the Action One by incorporating the field of specialization as a part of one SQL statement, so that you never actually extract the field of specialization from the DB. I.e. something like this: SELECT article_title, article_text FROM app_user, article WHERE app_user.user_name = ? AND app_user.field_of_specialization = article.field_of_specialization Alternatively if you still want to do 2 actions, I have seen people handle it in various ways: (1) get the action-forward in your action and modify the path to add a query_string with your keyValue on it (2) put the keyValue in a cookie (3) as you said, put it in the session. 2 3 have the disadvantage that they could be overwritten if the user has more than one browser window open.

RE: dynamically populating options in form
Well at the least you would probably want to use some javascript to trigger the submission of the form onchange of the first select so that you can populate the second select based on the first's value over on the server side and then redisplay the form. To do it without any javascript you would need to use a second submit button to do this, which the user would need to click after having entered a value in the first field. -Original Message- From: Anindito De [mailto:[EMAIL PROTECTED] Sent: Thursday, 6 November 2003 19:00 To: [EMAIL PROTECTED] Subject: dynamically populating options in form Hi, We have two select boxes in an HTML form.

RE: dynamically populating options in form
Something like Below ..
The Onchange event will trigger the Submission to another action which
then keeps the collection in request/session scope and select Box B is then
populated ..See the code below ..
script
function callAction(){
document.forms[0].action =
%=request.getContextPath()%/populateAction.do;
document.forms[0].submit();
}
script
html:select property=A onchange=callAction();
html:options collection=collection1 name=Form
property=value labelProperty=label /
/html:select
html:select property=B
html:options collection=collection.areas
name=Form property=value labelProperty=label /

Subject: RE: dynamically populating options in form
Well at the least you would probably want to use some javascript to trigger
the submission of the form onchange of the first select so that you can
populate the second select based on the first's value over on the server
side and then redisplay the form.
To do it without any javascript you would need to use a second submit button
to do this, which the user would need to click after having entered a value
in the first field.

Subject: dynamically populating options in form
Hi,
We have two select boxes in an HTML form. Based on the option that the user
selects in the first box and some other considerations, the contents in the
second box get populated. Are there any reasonable means of doing this in
struts with minimal use of JavaScript ?
Thanks in advance

Re: Re[4]: EL Expression in html:hidden tag
Yup, that's the theory anyway. As of JSP 2.0 (with a Servlet 2.4 format web.xml
that has not explicity deactivated EL evaluation), request-time attribute values
can be specified using either the familiar scriptlet expression (%= %) or the
EL (${}). So, any pre-JSP 2.0 tags that have attributes with
rtexprvaluetrue/rtexprvalue in their TLD file will automatically be able to
use the EL for request-time attribute values.

Re: [OT] Security Folter
I haven't tried it myself, but I did get a bug report from someone trying to do that. The bug was fixed, so I think it is working now. SecurityFilter doesn't come with any realm implementations(*), but you can use the CatalinaRealmAdapter to wrap a realm from Tomcat that will do password encryption for you. -Max (*) It does come with a trivial realm for the example app, a SimpleRealmBase class that can be extended if you want to write your own simple realm and not have to deal with Principal objects, and it comes with the CatalinaRealmAdapter, which allows you to use any of the realm implementations that come with Tomcat.

data-source connection keeps closing
After days of googling and trawling through the mail archives, I still
can't find any explanation for this... I'm trying to get a DataSource
that's been configured in struts-config.xml and use the connection in
my Model.
Every time I try to use the connection it says that it has closed
(before even getting the chance to create a statement!). The connection
that is returned sure enough has the correct URL, user, password
driver, and independent tests have confirmed that mysql is running,
that permissions are acceptable for that user, it's accessible from
Java, blah blah...
I've looked through most of the examples listed on the struts resources
pages, but I can't seem to find anything that has a simple
direct-to-jdbc example. Currently I'm not in a position to be using
anything like Hibernate, etc, so all those examples are kinda not
helpful in my situation.
QUESTION: Does anyone have a simple canonical example of connecting to
a JDBC database (preferably MySQL) via struts?
I'm using Tomcat 4.1, MySQL 4.1.0, MySQL Connector 3.0.9 and struts 1.2.

Subject: data-source connection keeps closing
After days of googling and trawling through the mail archives, I still
can't find any explanation for this... I'm trying to get a DataSource
that's been configured in struts-config.xml and use the connection in
my Model.
Every time I try to use the connection it says that it has closed
(before even getting the chance to create a statement!). The connection
that is returned sure enough has the correct URL, user, password
driver, and independent tests have confirmed that mysql is running,
that permissions are acceptable for that user, it's accessible from
Java, blah blah...
I've looked through most of the examples listed on the struts resources
pages, but I can't seem to find anything that has a simple
direct-to-jdbc example. Currently I'm not in a position to be using
anything like Hibernate, etc, so all those examples are kinda not
helpful in my situation.
QUESTION: Does anyone have a simple canonical example of connecting to
a JDBC database (preferably MySQL) via struts?
I'm using Tomcat 4.1, MySQL 4.1.0, MySQL Connector 3.0.9 and struts 1.2.
Error is as follows:

Re: upload validation failures are blanking my form values
it's not quite the same problem as that guy is having. I don't mind file fields being blanked, because chances are the validation error is from that particular file being too big. my problem is that every single field in the form is being blanked (ie text ones which describe the file too, not just the file one), and that this only happens when you upload a file (ie it won't happen on exactly the same page if you don't try to upload the file and there is a validation error). i think this must be a bug in struts, caoilte On Thursday 06 November 2003 14:33, Susan Bradeen wrote: Maybe this archive thread can help you? http://marc.theaimsgroup.com/?t=10475202833r=1w=2 Susan On 11/06/2003 06:22:05 AM Caoilte O'Connor wrote: Hi, I've got a bizarre bug with the struts-upload tools.

RE: Struts-Validation
yes Rickas exactly like what you mentioned what I did is first I just called
super.validate() in my validate method of ActionForm then did the custon
validation...btw is there any way in which I can validate those fields in framework
itself..??? one like NotRequiredIf...??
like I should restrict the user to enter either CreditCardId text box or radio button
which represent NoCreditCardId and not both If so I should throw err msg.

These option I think is to use the validate method in your
ActionForm and then first call your validation framework and then do
the check for the custom stuff you need to take care of
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
ServletContext application = getServlet().getServletContext();
ActionErrors errors = new ActionErrors();
//parameter will tell it what validation to look at
String parameter = request.getParameter(
mapping.getParameter() );
Validator validator = Resources.initValidator( parameter,
this, application, request, errors, page);
try {
validatorResults = validator.validate();
} catch (ValidatorException e) {
log.error(e.getMessage(), e);
}
//!! now do the custom stuff.. comparing the fields etc and add
//any more errors to errors
return errors;
}

RE: html:submit and 2 buttons
I have often added form properties to represent flags for the different
button actions to process. My ActionForm would have two properties
update and new:
setUpdate(boolean flag){}
boolean isUpdate()
For the submit buttons:
html:submit property=update value=true /
If I have to use an image for the submit button I generally will have a
hidden flag form field that I populate in the JavaScript onclick event
handler.

Your action can read the value attribute of your
submit tag. This is the label in your case.
bean-el:message key=search.new/
Use the request.getParameter to find out which button
was clicked. Give each of your submit buttons a
different NAME. request.getParameter(NAME) will return
the label of the submit button clicked or null.

[OT - Design] Needing Fast Access to 300,000 Records
Hi All - I've been trying to figure out a good way of handling something, and just can't quite seem to get a grip on the best approach. Here's what I've got: Two database tables - Table 1 has a BILLING_CODE and an ACCOUNT_CODE. Table 2 has the ACCOUNT_CODE and other account information (name, address, etc.) The tables are linked by ACCOUNT_CODE. Table 1: Table 2: BILLING_CODEACCOUNT_CODE ACCOUNT_CODENAMEADDRESS ... 1234ABC1 ABC1blahblah 1234ABC2 ABC2blahblah 1234ABC3 ABC3blahblah 5678DEF1 DEF1blahblah 5678DEF2 DEF2blahblah I need to be able to rapidly access the information in table 2 either through the BILLING_CODE, or directly through the ACCOUNT_CODE. I can create a POJO containing the BILLING_CODE and a List object to hold a second POJO for the table 2 info. Or I can use a Map. Either way doesn't give me a good method of accessing the table 2 information based on ACCOUNT_CODE. Two other bits of info - the combined number of records exceeds 300,000, so I have a scaling issue. Second, I'd like to load everything in a plug-in using iBatis dbLayer and store it in application scope (to eliminate db calls as the webapp is used.) Does anyone have any experience in handling something like this? How did you do it? Thanks...

RE: [OT - Design] Needing Fast Access to 300,000 Records
Vic - This is still in the design stage, so I don't have a SQL statement to provide. I'm looking for the best approach to handling what is essentially a table lookup where I need two keys (BILLING_ACCOUNT and ACCOUNT_CODE) The scenario is this: When one of my clients logs on to the webapp, the app determines the BILLING_ACCOUNTs the client has assigned, then explodes the BILLING_ACCOUNTs into the composite ACCOUNT_CODES. As an example, I've got one client with 54 BILLING_ACCOUNTs; these explode to over 30,000 ACCOUNT_CODES. I am trying to eliminate 30,000 db calls to get the account information - that's why I'm looking to pre-load the table(s) in a plug-in and access everything in memory. Make sense?

RE: struts-menu and internationalization
A quick look at the source code suggests that the locale used is either the loacle of the request (set by your browser) or some locale object in some scope. You need to tell the menu:useMenuDisplayer tag how to access your locale object. If for instance you put the user's locale in session scope with a key user.locale then you should use the tag like: menu:useMenuDisplayer name=listMenu bundle=org.apache.struts.action.MESSAGE locale=user.locale Disclaimer: I don't use this functionality - I've just had a quick look at the code.

RE: [OT - Design] Needing Fast Access to 300,000 Records
To avoid having 300,000 records sitting in memory I generally have my queries return record id's. My DAO returns an int[] or ResultObjects collection containing record id's that I store in some scope(session) as it takes little mem. The records are not generally all displayed at once so I only fetch the records that will be displayed on a single page and use a pager tag lib to provide paging functionality. The actual recordObjects currently being viewed are put into request scope to reduce mem consumption. Not sure of your iBatis plug-in but maybe you could still page the records and only pass one page of records at a time and use the strategy above.

Token and workflow
Hi everyone, I asked for some questions about token and double submissions a couple of weeks ago. Today, i'm back to that problem and more specifically on the workflow. The double submission detection is Ok. But i don't know how to retrieve the normal flow of the application. I explain myself : In my Prepare Action, i use the saveToken() method. Then, the JSP is shown and the user can fill the form. In my Process Action, i use the isTokenValid() then resetToken() methods. If there's just one submission, everything works fine. If there's a double submission, my Process Action class detects it and returns to the JSP (via the Prepare Action class) with an error message on the screen. Everything's fine until this point. But then, what happens ? The user can see the message but nothing can happen.. I can't retrieve the workflow of my application and the user remains on that page with this message whereas the first call of the Process Action class is already finished.. I spent a lot of time on the web searching for examples but unfortunatly, i couldn't find something that suits to my problem.. Thanks in advance, Frederic - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

After days of googling and trawling through the mail archives, I still
can't find any explanation for this... I'm trying to get a DataSource
that's been configured in struts-config.xml and use the connection in
my Model.
Every time I try to use the connection it says that it has closed
(before even getting the chance to create a statement!). The
connection that is returned sure enough has the correct URL, user,
password driver, and independent tests have confirmed that mysql
is running, that permissions are acceptable for that user, it's
accessible from Java, blah blah...
I've looked through most of the examples listed on the struts
resources pages, but I can't seem to find anything that has a simple
direct-to-jdbc example. Currently I'm not in a position to be using
anything like Hibernate, etc, so all those examples are kinda not
helpful in my situation.

a JDBC database (preferably MySQL) via struts?

Re: [OT - Design] Needing Fast Access to 300,000 Records
This should all be done is SQL. At a design stage, you take your outputs (mock up html pages or reports. I am sure you or anyone has a screen with 30,000 records on it, or even a 1,000) and do some data model. Based on your analysis you should know the SQL. If this is hard for you, then attach a html mock up of you screen one and screen 2. I will write the SQL for you based on those requirements. So far I think it's a simple 2 way join (people write 12 way joins, or 10 page stored procs, quite possible you are concrend about a problem that does not exist. I tell you it's sub second! Also you just went from 300,000 to 30,000... maybe it's 3,000 or 3,000,000. It does not mater the records, it's a 2 way equi join. ) Recomendation to the list: Please read Celcko's SQL for Smarties, my all time fave for designers. .V Jerry Jalenak wrote: Vic - This is still in the design stage, so I don't have a SQL statement to provide. I'm looking for the best approach to handling what is essentially a table lookup where I need two keys (BILLING_ACCOUNT and ACCOUNT_CODE) The scenario is this: When one of my clients logs on to the webapp, the app determines the BILLING_ACCOUNTs the client has assigned, then explodes the BILLING_ACCOUNTs into the composite ACCOUNT_CODES.

Token and workflow
Hi everyone, I asked for some questions about token and double submissions a couple of weeks ago. Today, i'm back to that problem and more specifically on the workflow. The double submission detection is Ok. But i don't know how to retrieve the normal flow of the application. I explain myself : In my Prepare Action, i use the saveToken() method. Then, the JSP is shown and the user can fill the form. In my Process Action, i use the isTokenValid() then resetToken() methods. If there's just one submission, everything works fine. If there's a double submission, my Process Action class detects it and returns to the JSP (via the Prepare Action class) with an error message on the screen. Everything's fine until this point. But then, what happens ? The user can see the message but nothing can happen.. I can't retrieve the workflow of my application and the user remains on that page with this message whereas the first call of the Process Action class is already finished.. I spent a lot of time on the web searching for examples but unfortunatly, i couldn't find something that suits to my problem..

Re: Best Practices in Struts for Form objects?
Hello it totally depends what you need. different names: if u use different names than there will be created five different forms, each under an other name. if all are in request it makes not really sense to do this because they are deleted if the request is over. but if you use them in session then it could make sense then you could have up to five formbeans in scope and get to their values every time, but you have to know which form you actually need if they are stored under the same name then only once is created the formbean so values will be availble for every action which uses it (except you explicite destroy it) Michael - Original Message - From: Michael Cardon [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, November 06, 2003 4:35 PM Subject: Best Practices in Struts for Form objects?

Re: Best Practices in Struts for Form objects?
you probably only want one form set to request scope. If you use different forms, then that form is only valid for the one specific action it is associated with. For instance, if the submitting page contains a form that has a textbox where you can input your name. And you want to display the name on the next page using struts internal form processing, then the forms must be the same. As far as scope, I think you almost always want to use request scope. Session scope does wacky things. Don't think of the data as only being request scope - because as long as your workflow has that form in each page with the associated parameters(if you're not displaying them but need them preserved between requests - use html:hidden) then the data is almost like being session scoped.

Re: Reusing Validation
Resending this since haven't got any responses for a day In summary, here is my question. For those needing more details, look at the entire text below. Is there a way to re-use the validation that is already built on all forms using validator framework? If so how? If not, how can I centralize my validation to one place? Thanks [EMAIL PROTECTED] 11/05/03 10:35AM Hi All, We are developing an intranet site to replace a legacy system which is in place. Legacy system does not have as much extensive validation as the new application does. Intranet site rollout is going to be phased out due to several reasons. While legacy system is up, we have a batch process that transfers data from legacy system to our new database. On the new application, data is entered using work flow format where all data is collected across forms into a mama bean. At the end summary page is presented before data is persisted to db. Most of form validation is done using validator framework. Now, users want to edit legacy data that has been brought over. When they open an existing event, we present them with summary page. Then the user has the option to go to any form in the wizard flow using navigation on left. Since legacy data is not validated, we would like to validate all the data in mama bean and present them with visual indicators for each form in the wizard flow that fails validation. This makes data clean-up very easy. Here is my question. Is there a way to re-use the validation that is already built on all forms using validator framework? If so how?

Re: multibox - Null attribute name ServletException - SOLVED
I change html:iterate tag to:
logic:iterate id=item name=multiboxTest property=items
the =multiboxTest is the ActionForm bean's name in struts-config.xml.
and add getter/setter for items, now it works.
Thanks.

RE: logic:equal using form bean property?
My container is Resin 2.1.10 supporting Servlet 2.3, but have not yet
played with any JSTL tag's will convert as a last resort.
The method signatures are as follows:
public void setPid(String id)
{
m_pid = id;
}
public String getPid()
{
return m_pid;
}
Thanks,

If you're using a Servlet 2.3 container you should use the JSTL's
c:forEach and c:if tags instead of the Struts tags. What do your
getter and setter method for pid look like?

Hi All,

logic:iterate name=products id=product indexId=ctr

This code generates the following error:
Error: No applicable overload for the method named setValue was

But when I use a request parameter to indicate the index it works
fine:

logic:equal name=pid value=%=ctr%
Any help is much appreciated.

RE: Dynamic Image from DB to JSP
Marc, That's a tricky one I've planned for but haven't started yet. My research showed the html:img tag should be used with a path. That path can invoke an action (direct, not tiled) that sets the content-type to the right type of image then tosses out the binary stream. So, it should be something like this: html:write get a URL such as /images.do?id=555 or http://somehost/images.do?id=555;. Then your map an action for /images to set the content type, open the database, and print the binary stream appropriately. Sounds a bit list an advertising program, almost. :) If something else works for you, please let me know as this is type of image display is on my to-do list.

You can also specify a default filename for the image through response.setHeader(Content-Disposition,filename= + imageFilename); so when the user attempts to save the image, he/she doesn't get images.do as the default. --- David Friedman [EMAIL PROTECTED] wrote: Marc, That's a tricky one I've planned for but haven't started yet.

RE: Usar tipos de datos como Timestamp, BigDecimal
Milton, Puedes usar el org.apache.commons.beanutils.BeanUtils.populate metodo o crear tu propio metodo en tu action class donde mapeas de string a el type que es correcto. Solamente que tienes que ser un poco cuidadoso con los Timestamp, you uso una conbinacion de BeanUtils populate y mis propios metodos.

getting current session in ActionForm

Re: getting current session in ActionForm
you can do it during the reset which is sent the request along with the actionmapping.

Redirect to remote website using ActionForward

Struts Dilemma
Often when writing a bean for use by a tag, I seem to be writing a equivalent method that returns a string value for a boolean property. For example: If I mean to pass a boolean property isInactive, I am also writing a getInactiveFlag which returns N or Y based on isInactive. I use inactiveFlag in my tag definition and inside my tag I check for Y or N. Am I totally missing something or is there a better way to do this?

Question on storing bean in request context
Good morning (again)
I have an Action that is retrieving a javabean object from my database
(via iBATIS, thank you very much :)) and I need to store that bean
somewhere where a Tile can access it. What I'm doing, is storing it in
the request context (request.setAttribute(item,item)) and then my
Action returns a forward that is mapped to a tile definition. That tile
definition assembles a collection of tiles (which is all working) - the
tile that needs to access the information in the bean, then does this:
jsp:useBean id=item scope=request type=com.fiskars.webpdb.ItemBean
But, when I try to output something, like c:out
value=${item.productName} - I get nothing, no errors, no exceptions,
nothing.
Any ideas?

Best Practice : session vs. request attributes
I'm questioning my current design practice regarding Struts forms. Until now, I tend to store all client data in the Struts form and I avoid using other request attributes or session attributes. But, this approach seems limited when I need to display a collection of objects that are very polymorphic. Let's say I need to display a collection of instances of different classes A1, A2 and A3, that all extend the same parent class A. A1, A2 and A3 have a very limited number of common properties (described in class A). If I store the collection of A's in the Struts form (as in indexed property), I do not know to to code a logic:iterate tag in the JSP in order to make sure that I won't loose data from request to request (what preoperty attribute can I write for this tag ?) : logic:iterate name=myForm property=collection_of_As id=A type=WHAT SHOULD I WRITE FOR THIS ATTRIBUTE Therefore, in this case, I want to use a session attribute to store the collection of As. Of course I won't loose client data from request to request (action forward). What is your point of view regarding this matter ? Is it OK using session attributes (performance, memory, etc. ), even if you make sure session attributes are removed when no more needed ?

RE: Struts Dilemma
I think the best way to avoid this is to always use Strings and only Strings for all form values (except Collections). Then your action class can convert to/from the desired type when it creates the transfer object to pass to the business delegate. If you combine this approach with the struts validator then you know you can safely create the desired type (for instance java.util.Date) without throwing an exception. -Original Message- From: Srinivas Gunturu [mailto:[EMAIL PROTECTED] Sent: Thursday, November 06, 2003 12:30 PM Subject: Struts Dilemma Often when writing a bean for use by a tag, I seem to be writing a equivalent method that returns a string value for a boolean property.
