HREF link question
Hi, I'm trying to use href links with Struts templates, and can't figure out how to make my href links work properly. [Templates seem to work just fine, otherwise.]... my compliments. 1. I want to use Struts html:link tags so that to automatically do URL session encoding. 2. I want to use absolute URLs to make coding of urls more robust. For example, if I have a directory structure of JSPs: jsp jsp/prodinfo jsp/faq ...I want to be able to code the url something like... jsp/faq/faq1.jsp or jsp/prodinfo/info1.jsp, in case I change the directory structure, rather than using relative links, e.g. ../faq/faq1.jsp. 3. For the portion of the website that I'm currently working on, I am creating href links from one JSP to other JSPs. [For other portions of the website, I will be using an MVC architecture, hence forwarding from a servlet to a JSP and vice versa.] 4. I have tried various approaches to using the html:base/ tag in the HTML HEAD section of my Struts template file, not using a base tag, and have tried using the following to set the html base: BASE HREF=%= http://; +request.getServerName() +: +request.getServerPort() +request.getContextPath() %/ Although the latter works with regular a href tags, it does not seem to work with html:link Struts tags. I have tried a variety of combinations of these base tags with a variety of combinations of url encodings, but cannot seem to get them to work -- except with regular a href tags using the BASE HREF=%= http://; +request.getServerName() +: +request.getServerPort() +request.getContextPath() %/ base tag setting. Thank you in advance to anyone who can help, Rick Horowitz
Internationalization (I18N) query
Hi All, This is a typical requirement about the internationalization. I want to create an application to be displayed in English and Japanese. Also, the user has given facility to customise some of the display field names for him. Now, question arises, do we need to provide the internationalization for these cutomised fields. What is the general trend for this and Is it feasible to do this? e.g. if an english user change field name like employee_name to empl_name, what if next time when he logs on selecting locale as Japanese. What should we display, empl_name literal in english or something else in Japanese, like default setting for that field in Japanese? Kindly forward your suggestion for such kind of Internationalization. - Sandeep
Re: Please confirm css ok from client-side jscript validation
Cheers 4 that advice , i did try the javascript declartion and inclued
the javascript code directly , thus the jsp worked but no javascript event.Thus
i 'll try the src (source).
I have a created a javascript file at the same level as the CascadeStyle
Sheet - ( /struts-bbnpa / css/ graphics ) thus do i do the same
i.e ( struts-bbnpa / javascript/ ) and must i add the js extension
to javascript file when i amend it later within windows.Thus shall i create
html page with the embeded js code within the js file.
cheers chuck ( trying it out )
SCRIPT language="JavaScript" src="myJavascriptFile.js">/SCRIPT>
Or include the javascript code directly:
SCRIPT language="JavaScript">
function myFunct() {}
/SCRIPT>
and call methods from whichever event you want: onLoad, onClick, etc
HTH,
Pete

RE: Type conversions - issues on where to do them
1) If I do it in the ActionForm and there is a problem in the Action, then I have to reconvert back to a String on the way back.; That's why I advocate that properties in an ActionForm should be Strings instead of dates/ints/whatever. Why not let the ActionForm do all simple conversion and validation? The request object still has the String versions. Jonas

Storing Edited elements from an html form in a collection
Hi All, Unfortunately nobody has answered to my mail on 06/13/2001 (How to access getIndex method of iterate tag in a jsp page). Indirectly Martin Cooper replied (Re: Iterate tag update), but this can only be accomplished by a new struts version which he will publish this afternoon. What I like to do is to edit a collection of data in a form. The collection is displayed using the logic:iterate tag. How do I store the modified values in the right element of the collection? Can somebody please post a jsp code snippet of how this is done using struts?

Server-side form validation - anything in STRUTS?
Hi all. Does STRUTS contain a framework for server-side form validation? It's obviously a very common requirement - to check that values entered into an HTML form conform to certain criteria. As I see it, these criteria fall into: 1. per-field validation - checking that a text box is not-empty, setting a max size for a field, disallowing certain characters 2. intra-field validation - eg for a 'date' section, checking that 'day', 'month' and 'year' are *either* all entered *or* all not entered 3. full-form validation - eg all fields in the form are allowed to be blank individually, but at least one of them must not be blank Has anyone seen anything 'out there' that tackles this somewhat thorny issue? I can see that there's a need to provide quite a few different types of criteria at all three of the above levels. For my own reasons, I do *not* want to rely on client-side validation - I need to do this on the server. An interesting article at http://www.javaworld.com/javaworld/jw-03-2000/jw-0331-ssj-forms_p.html has started me thinking about this, but if deals with only 'per field' validation. Cheers Dave

Re: ActionForms for read-only data??
Craig, The ActionForm class definition seems to imply that it was intended to contain only editable data (i.e., the reset and validate methods). Distinguishing between read and write functionality in the enterprise systems I have developed was always a major advantage, both in extensibility and code maintainability, as usually each type of functionality had different processing requirments. It seems that if we mix read and write functionality into one ActionForm instance, we will have some bulky classes to maintain. Any comments? Thanks. From: Craig R. McClanahan [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: Re: ActionForms for read-only data?? Date: Mon, 11 Jun 2001 17:01:31 -0700 (PDT) On Mon, 11 Jun 2001 [EMAIL PROTECTED] wrote: I have a Struts theory question on use of action forms versus java beans for read-only data. We have extended workflow on our website such that the same form can look a bit different depending on where you are in the workflow. For example, the quote request will have limit and retention fields in the business request section. Once you get to quote, those fields are read-only and there's an additional quote amount field. When the client requests binder, all those fields are read-only and there is a checkbox. Once bound, everything is read-only. There is some disagreement on the team as to how to handle this case. We will obviously have four JSPs, one for each of these presentations. The question is the data mapping to beans. Half of the team feels that to use Struts in its purest sense, we need to have java beans that represent the read-only data, and action forms to represent the editable data. That would mean four action forms, one for each JSP. The other half of the team wants to re-use the same action form for all four cases, bean:define it in the session, and use bean:write to print out the data if read-only. The major advantage is simplicity - we have one bean that represents all of the data - there is no need to understand what part of the workflow we are in when translating the data from the data model to the presentation layer beans. It is also easier to understand for an HTML programmer or developer that the same bean is used regardless of whether it is a bean:write or any of the html tags. We certainly don't want to end up in a position where we have broken the framework and hurt our extensibility in future releases. The first scenario would seem to follow the framework more closely, but in this special case, is it a problem to deviate and use the ActionForm for what it is - a bean? We would appreciate any advice and experiences. Thank you. Ted covered a couple of the issues in his response -- I'd like to add a few more thoughts. I don't think there are cut-and-dried answers to an issue like this, so it's a question of balancing the tradeoffs. If you are using the same JSP page itself for the different views of the same information, you probably already have conditional logic in it about whether to make a field editable or read only. In such a case, I don't think it necessarily violates the Struts philosophy to use the same ActionForm bean. In fact, the Struts example application includes a miniature example of this use case like this: logic:equal name=registrationForm property=action scope=request value=Create html:text property=username size=16 maxlength=16/ /logic:equal logic:equal name=registrationForm property=action scope=request value=Edit bean:write name=registrationForm property=username/ /logic:equal which makes the username field editable in create mode, but read only in edit mode. Note that you do not actually have to use bean:define to introduce the ActionForm bean if it's the same bean used in your html:form tag -- the standard Struts logic will introduce it for you. It can be used exactly like any other bean, from within the nested body of the html:form.

Problems with session scope forms disappearing
Hi Everyone, I've been using Struts for a while now, and have come across a problemwhereby trying to pass a form (with all struts-config entries being scope="session") between multiple different actions (same form) will lose all previously entered data - I'mtrying to map each page in a process to an action class, however I'm not writing the data to the database until the last page has been submitted as the user may want to go back and foward several times. Should it be possible to do this ? I've got a number of actions working with different action entries (ie. paths), however pointing to the same type (ie. java action class)and form to allow different pages to have different 'success' and 'failure' mappings, however I've found that a few of these classes are becoming quite large and unmanageable, and I would like to clean this up by having a different action per web page, but only 1 form for all data. Any help would be gratefully received.. Regards, Don Elliott
Re: Iterate tag update?
* Martin Cooper [EMAIL PROTECTED] 2001-06-13 (21:42:47): I just checked in a change to the iterate tag which allows you to access the current index as a scripting variable. If you specify the 'indexId' attribute, a scripting variable with the specified name will contain the current index (as an Integer) on each iteration. This will be available in the 6/14 nightly build, and also in Struts 1.0. i think this is exactly what i needed recently..after all i cannot follow 100percently right now. would be great if you can post a snippet where you do such a iteration and use this feature. thx alot. - fw -- \|/ \|/ --([EMAIL PROTECTED])- @~/ ,. \~@ /_( \__/ )_\ waste of money, brains and time - wombat() \/ -

-Original Message- From: Kyle Brown [mailto:[EMAIL PROTECTED]] Sent: 14 June 2001 12:24 Hi Kyle, Thanks for this response. Have you read any of the Struts documentation? If you mean the User Guide on the STRUTS site, yes I have. But it doesn't include much of a 'discussion' on form validation - that is why I have tried to start one up... Also, you could go to my article on the VisualAge developer's domain about why you want to use Struts I have now looked at this - thanks for the pointer... Of couse, the documentation also makes this perfectly clear... It's perfectly clear how a single form can be validated within STRUTS (thanks to Wellington Lacerda for his input and clarification too). However, your article points to implementing the 'validate' method in a very low-level way, coding the validation logic on a per-form basis as required. I guess my real question was whether STRUTS had taken a higher-level abstraction of the validation required, so that form validation can be expressed external to the Java code (eg. in a properties file). Wellington Lacerda ponits out that 'Inside the validation method you can use any kind of logic you want' - is there any work on generalising this logic? Thanks for you time on this one :) Dave
Dreamweaver and Struts 1.0 - updated translator now available..
Hi Everyone, Recently I downloaded from husted.com an old Dreamweavertranslator for Struts 0.5 to use in coding my Struts 1.0 JSPs, however I've had a lot of problems with it... I've since converted this to support most 1.0 HTML tags, and have been using it fairly successfully in conjunction with a JSP include extension found on the dreamweaver site. If anyone is interested in a copy of this I'm happy to provide - please email me on [EMAIL PROTECTED] and I'll send the translator + instructions via return email... Regards, Don Elliott www.i4-talent.com Melbourne, Australia FYI - the translator basically converts Struts HTML tagsinto normal html tags so that the design view of Dreamweaver will show you what the page looks like - without this, the page just looks like a bunch of little squares that represent ASP / JSP code. I've spent quite a bit of time commenting the code so it should be easy to add the tags I already haven't. The few known issues are as follows: - dreamweaver goes bananas when it finds a Struts tag that has been commented out and replaces it with a bunch of MM:taglock ... junk in your source file (be careful of commented out tags !! By commented out, I mean within % /* ... */ % or % // ... % comments, or event !-- ... -- tags. - doesn't support any iteration tags, however if these are coded nicely will ignore these which makes little difference to the way your screen looks.

Re: Problems with session scope forms disappearing
I think you got this behaviour because Struts is calling the reset() method before of the form populating it, so the form is reinitialize betwen each actions. You can solve this problem by having a blank reset() method and a realReset() method that you can from your action class when needed.

Any help would be gratefully received.. Regards, Don Elliott
[Not registered, use system identifier] - the cause of my prob?
Hi there fellow struts users!
Making struts work with VAJ 3.5.3 WTE is causing me no end of grief.
I managed to get struts working with WAS 3.5.3 thanks to indispensible help
from you guys. I then copied everything from my WAS struts
installation except:
I imported the struts 1.0b1 source into VAJ instead of deploying the
struts.jar file in my classpath.
I followed the instructions at:
http://www7.software.ibm.com/vad.nsf/Data/Document2558?OpenDocumentSubMast
for installing the JAXP parser in VAJ 3.5.3
Although, I'm quite sure my classpath is OK, I end up with a 505 error (see
end of doc). When I start the WTE i get messages saying:
resolveEntity('null',
'http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd')
Not registered, use system identifier
Right now I suspect these messages are at the root of my problem. Is that
probable?
How do I get rid of those?

RE: [Not registered, use system identifier] - the cause of my prob?
Next to the java sources you also have to import the resources in VAJ.
You can do this by importing them from the struts.JAR but only select the
resources.
Maybe this will solve your problem.

Visual editing of Struts tags
One of the main ideas of the MVC approach of Struts is making it easier for non-programmers to do the view editing. Although the idea is great, the problem for me as a developer is the lack of tools for editing JSP with custom tags. I have some questions about this: 1) I know that Dreamweaver UltraDev 4 can be customized to Struts. Can this be done with any other editors? It does not seem like WebSphere has this feature. Sure, custom tags can be added, but there is little visual support. 2) Has someone written a good documentation of the Struts tags for non-programmers that prefer to use text editors? Although the Struts documentation is fantastic, it does require some programming knowledge. 3) One approach is to use html-code as much as possible until editors support custom tags better. This means using the Struts controller, with a minimal use of custom tags in the JSP files. The Blazix form tags is one example of doing form editing in almost-html. Values are inserted into the form by enclosing the form in tags blx:getProperty name=testBean property=* ... html form... /blx:getProperty Although the Struts tags are clearly better, this approach seems easier to use with for example WebSphere. Unfortunately, the source code does not seem to be available. Has anyone else done anything along these lines? Jonas

I have been unable to use this method to restrict access to specific requests, say 'action1.do'. I assume this is because only the resources are protected (i.e. the actual JSPs). The upshot is that I am protecting the whole web-app using url-pattern/*/url-pattern. This is fine. It is an intranet site and it means that I can use request.isUserInRole() and request.getUserPrincipal() in the confidence that I know the user has been forced to authenticate themselves. The problem comes when I want to restrict certain actions based upon the user's role. In the perform() method of my Action class I have to use request.isUserInRole(). I would like to be able to do this declaratively rather than programmatically, either using the security-constraint declaration in web.xml, or possibly as part of the action declaration in struts-config.xml. Question1: Have I missed something obvious in my use of the security-constraint mechanism? Have you tried a URL pattern like this? url-pattern/action1.do/url-pattern The syntax of URL patterns used in security constraints is exactly like that used in servlet mappings, and this would be an exact match pattern for path /action1 (assuming you are using the usual *.do mapping for the controller servlet). Question2: If not, would this make a useful extension to the Struts framework? I've thought about the idea of incorporating role-based checking into the controller servlet itself, but it seems like a duplication of what you can already do in the container (such as the above). However, a place where it might be useful is if you have a scripted workflow of some sort, and certain steps would be executed or skipped based on the roles possessed by the authenticated user.

Re: Server-side form validation - anything in STRUTS?
More support for implementing validations is on the list for the 1.1 timeframe. The leading contender here is David Winterfeldt's extension. Highly recommended. http://home.earthlink.net/~dwinterfeldt/ The most popular pattern is to perform domain validations in the ActionForm to ensure that the String can be converted to a native type. And then perform range validations in the Action, which may need to reference the business logic tier. The actual data-type conversion can be done anywhere along the way. -- Ted Husted, Husted dot Com, Fairport NY USA. -- Custom Software ~ Technical Services. -- Tel 716 737-3463. -- http://www.husted.com/about/struts/ Dave Small wrote: It's perfectly clear how a single form can be validated within STRUTS (thanks to Wellington Lacerda for his input and clarification too). However, your article points to implementing the 'validate' method in a very low-level way, coding the validation logic on a per-form basis as required. I guess my real question was whether STRUTS had taken a higher-level abstraction of the validation required, so that form validation can be expressed external to the Java code (eg. in a properties file).

Re: Please confirm css ok from client-side jscript validation
The source (src) attribute should work. This can be very helpful if you
have common methods that you want to share across multiple pages.
SCRIPT language=JavaScript
src=/struts-bbnpa/javascript/myJavascriptFile.js/SCRIPT
notice the leading '/' and also, do you have the ending /SCRIPT tag,
this is required as well.
As for the js extension... here is an snippet from HTML: The Definitive
Guide by Oreilly.
The value of the src attribute is the URL of the file containing the
JavaScript program. The stored file should have a MIME type of
application/x-javascript; but will also be properly handled
automatically by a properly configured server if the filename suffix is
.js.
Looking at my computer, I have the MIME type set. However, I did not
set this manually. Either it was a default of windows, or an
application that I loaded added it.

Hi Dave, Try this http://home.earthlink.net/~dwinterfeldt/ Struts Validator - Validation Framework for Struts Hope this can help 8) -Original Message- From: Dave Small [mailto:[EMAIL PROTECTED]] Sent: June 14, 2001 5:51 AM To: [EMAIL PROTECTED] Subject: RE: Server-side form validation - anything in STRUTS? -Original Message- From: Kyle Brown [mailto:[EMAIL PROTECTED]] Sent: 14 June 2001 12:24 Hi Kyle, Thanks for this response. Have you read any of the Struts documentation? If you mean the User Guide on the STRUTS site, yes I have. But it doesn't include much of a 'discussion' on form validation - that is why I have tried to start one up... Also, you could go to my article on the VisualAge developer's domain about why you want to use Struts I have now looked at this - thanks for the pointer... Of couse, the documentation also makes this perfectly clear... It's perfectly clear how a single form can be validated within STRUTS (thanks to Wellington Lacerda for his input and clarification too). However, your article points to implementing the 'validate' method in a very low-level way, coding the validation logic on a per-form basis as required. I guess my real question was whether STRUTS had taken a higher-level abstraction of the validation required, so that form validation can be expressed external to the Java code (eg. in a properties file). Wellington Lacerda ponits out that 'Inside the validation method you can use any kind of logic you want' - is there any work on generalising this logic? Thanks for you time on this one :) Dave
Re: struts-config.xml - How do I open a success path as a new window???
Hi Abraham and Pete!
Thanks for your help! The problem is - I don´t use a link directly from my
jsp page to reach this new window. I have two submit buttons on my jsp-page,
Save and Insert Address . The form:action on the jsp-page is:
html:form action=/saveComposeMessageAction.do?action=Save
in Struts-Config.xml this action looks like this:
!-- Save compose message --
action path=/saveComposeMessage
type=com.appium.UM.Control.Web.Mail.SaveComposeMessageAction
name=composeMessageForm
scope=session
validate=false
forward name=success path=/ComposeMessage.jsp?action=Create/
forward name=success2 path=/viewInsertAddress.do?action=Insert/
forward name=failure path=/ErrorLDAP.jsp/
forward name=failure2 path=/ComposeMessage.jsp/
/action
If i click on the submit button InsertAddress, saveComposeAction is the
first action. From the action class I check if Insert Address was the button
the user clicked on, if this is the case I return success2 and the path is:
path=/viewInsertAddress.do?action=Insert/
The action in struts_config.xml looks like this:
!-- View insert address--
action path=/viewInsertAddress
type=com.appium.UM.Control.Web.Mail.ViewInsertAddressAction
name=insertAddressForm
scope=session
validate=false
forward name=successpath=/InsertAddress.jsp/
forward name=failurepath=/ErrorLDAP.jsp/
/action
From this class I return success and the path is :
path=/InsertAddress.jsp/
As it is now InsertAddress.jsp is onpened in the same window as the first
jsp-page but a want a new window!! Where do I enter this information and
how??
Any suggestions???
Thank you in advance!

Accessing session attributes
This is probably a stupid question, but here it goes. I have a handful of string values that I'm storing in the session object. These values aren't associated with any bean (actually, in a sense the session object is the bean). I have a couple of places where I need to display these values in a form. I want to use the html:text tag, but I don't know what I need to specify. Let me give an example. Suppose I have a String value stored in the session by the name of filter. How would I get the filter value to display in a form text field? Thanks.

Re: Accessing session attributes
The html tags are designed to display what's in a related ActionForm bean. So the trick would be to get your String into the ActionForm bean. The place to do this would be in an Action that then forwarded to your JSP. So the Action would go something like this: HttpSession session = request.getSession(); YourBean yourBean = (YourBean) session.getAttribute(yourBean); YourForm yourForm = (YourForm) form; yourForm.setWhatever(yourBean.getWhatever()); return (findForward(success)); You could use the same Action to handle the submit from the form, either by keying on a value in the form or by submitting to another Action Mapping with a different parameter property. If you don't need to display them in a HTML form, then you can just use the bean:write tag and specify the property you want to write (assuming it has a getYyyy accessor). -- Ted Husted, Husted dot Com, Fairport NY USA. -- Custom Software ~ Technical Services. -- Tel 716 737-3463. -- http://www.husted.com/about/struts/ James Howe wrote: This is probably a stupid question, but here it goes.

Re: struts-config.xml - How do I open a success path as a new window???
You could use javascript to set the target in the form tag to _blank if you want
it in a new window. As Pete said, however, the drawback is that they may have
Javascript turned off.

Re: Storing Edited elements from an html form in a collection

Multiple Forwards
Hi all, I am a relatively new struts user, so if the question I'm asking has been answered before, I appologize ahead of time. What I'm trying to do, is create a framework integrated with struts that, among other things, allows users to set up multiple forwards dependent on the broswer type. This could be Netscape, IE, WAP browser, or others. What I would like to do is something like the following in the struts-config.xml file: ... action name=test ... forward name=success browser=IE path=/ie/test.jsp/ forward name=success browser=NS path=/ns/test.jsp/ forward name=success browser=WAP path=/wap/test.jsp/ ... /action ... The reasoning behind this, would be to create an additional attribute that could be used by my framework internals that determines the browser and calls the correct JSP for the user automatically. Something like: ... return myMapping.findForward(success); ... Which calls into a wrapper class that I create and determines the browser, then calling the appropriate JSP as defined in the config file. This makes it very simple for the user, as he only needs to define a series of 'success's, and the Action code is simple as defined above. Now, obviously, adding an additional attribute to the forward above is not trivial. So my question, is has anyone seen anything like this, and is there a way I haven't thought of to do this within the current struts framework? One thought I've had would be to do the following: forward name=ie_success path=/ie/test.jsp/ forward name=ns_success path=/ns/test.jsp/ forward name=wap_success path=/wap/test.jsp/ This would work and not require many changes to the framework, but I would rather not do this, as it would make things very difficult for my users to create their own actions. Another possibility is the following: forward name=success path=test.jsp / browserforward name=success browser=ie path=/ie/test.jsp / browserforward name=success browser=ns path=/ns/test.jsp / browserforward name=success broswer=wap path=/wap/test.jsp / In this case, I would need to create another XML entry that kept all of the 'success' forwards for each action in its own little HashTable, much like the normal forwards, except keyed by a combination of the name and the browser attributes. I honestly don't know how difficult this would be, but it seems like the best solution I've come up with so far. One obvious drawback to this one is that the struts DTD would need to be altered to include the 'browserforward' element. I am not sure of the implications of this. Any thoughts?

Having problems passing more than one parameter with html:link tag
Hi, I am trying to pass 2 parameters with html:link.

I have found it best to use context-relative URLs starting with a / character throughout my applications, rather than trying to use relative links -- for the reasons that you are probably familiar with. To do that for links, use the page attribute to specify the destination -- Struts will prepend the context path of the current application for you, so that the browser always goes the right place. For example, you might code: html:link page=/jsp/faq/faq1.jspTo the FAQ/html:link 3. For the portion of the website that I'm currently working on, I am creating href links from one JSP to other JSPs. [For other portions of the website, I will be using an MVC architecture, hence forwarding from a servlet to a JSP and vice versa.] It works either way, but remember that links directly from one page to another bypasses the controller -- and therefore bypasses the stuff that the controller servlet does for you. 4. I have tried various approaches to using the html:base/ tag in the HTML HEAD section of my Struts template file, not using a base tag, and have tried using the following to set the html base: BASE HREF=%= http://; +request.getServerName() +: +request.getServerPort() +request.getContextPath() %/ Although the latter works with regular a href tags, it does not seem to work with html:link Struts tags. See the html:base/ tag for a way to do this automatically. However, whether you create it yourself or not, the base element affects only relative hyperlinks. If you follow my suggestion above (always use context-relative links), you won't need it. I have tried a variety of combinations of these base tags with a variety of combinations of url encodings, but cannot seem to get them to work -- except with regular a href tags using the BASE HREF=%= http://; +request.getServerName() +: +request.getServerPort() +request.getContextPath() %/ base tag setting.

nested logic:present tags do not short-circuit
Title: nested logic:present tags do not short-circuit Hi- Am I correct to say that in the case of nested logic:present tags, the false evaluation of the first one will not short-circuit, or prevent the evaluation of, the second one? For example, in the case that a Form has a Bean A, which itself has a Bean B, and when B is null, the following: logic:present name=A property=B logic:present name=A property=B.property some jsp/html /logic:present /logic:present will still fail because the second logic tag is evaluated and the null-pointer is dereferenced. If this is correct, is this by design? Is this a bug? Is there a way to accomplish what I am trying to do here? Any thoughts appreciated. Thanks, S-

Re: ActionForms for read-only data??
On Thu, 14 Jun 2001, hi there wrote: Craig, The ActionForm class definition seems to imply that it was intended to contain only editable data (i.e., the reset and validate methods). Distinguishing between read and write functionality in the enterprise systems I have developed was always a major advantage, both in extensibility and code maintainability, as usually each type of functionality had different processing requirments. It seems that if we mix read and write functionality into one ActionForm instance, we will have some bulky classes to maintain. Any comments? Thanks. There are probably multiple reasonable approaches to dealing with read-only data. Let's consider some of the ways you can do this: (1) Expose the data as JavaBeans *other than* the form bean: This is quite easy, since you can do things like bean:write to generate the output, logic: to test, and so on. However, you are mildly increasing the linkage between the model layer and the view layer -- now the developers have to agree on the bean name, and the properties to be used. The tradeoff is that you might be able to reuse beans (such as value objects in an EJB based app) that already exist. (2) Copy the read-only data into the form bean: This is particularly useful in several use cases: - You only want to access the data nested inside the html:form - You don't want to create the extra dependency on a bean name (since you can reference the form bean implicitly) - A particular property might be read-only in some uses of the form and read-write in others (see the username field of the RegistrationForm bean in the example application). However, adding new properties means going back and updating the form bean class every time, which can be tedious if it's not being automatically generated. In practice, I have used both techniques -- but in particular I find myself needing data outside the nested body of an html:form, in which case I really need to use technique (1) anyway. Part of my internal system documentation (for the various developers) is a clear description of the bean names (and scopes), and the properties that they expose, that the page developer can count on. This seems to deal with most of the manageability issues, but none of these apps have had a very long life yet since Struts has only been around a year :-). Craig McClanahan From: Craig R.

We have extended workflow on our website such that the same form can look a bit different depending on where you are in the workflow. For example, the quote request will have limit and retention fields in the business request section. Once you get to quote, those fields are read-only and there's an additional quote amount field. When the client requests binder, all those fields are read-only and there is a checkbox. Once bound, everything is read-only. There is some disagreement on the team as to how to handle this case. We will obviously have four JSPs, one for each of these presentations. The question is the data mapping to beans. Half of the team feels that to use Struts in its purest sense, we need to have java beans that represent the read-only data, and action forms to represent the editable data. That would mean four action forms, one for each JSP. The other half of the team wants to re-use the same action form for all four cases, bean:define it in the session, and use bean:write to print out the data if read-only. The major advantage is simplicity - we have one bean that represents all of the data - there is no need to understand what part of the workflow we are in when translating the data from the data model to the presentation layer beans. It is also easier to understand for an HTML programmer or developer that the same bean is used regardless of whether it is a bean:write or any of the html tags. We certainly don't want to end up in a position where we have broken the framework and hurt our extensibility in future releases. The first scenario would seem to follow the framework more closely, but in this special case, is it a problem to deviate and use the ActionForm for what it is - a bean?

Re: Having problems passing more than one parameter with html:link tag
I think you would need to use a map here. http://jakarta.apache.org/struts/struts-html.html#link Normally, the hyperlink you specify with one of the attributes described in the previous paragraph will be left unchanged (other than URL rewriting if necessary). However, there are two ways you can append one or more dynamically defined query parameters to the hyperlink -- specify a single parameter with the paramId attribute (and its associated attributes to select the value), or specify the name (and optional property) attributes to select a java.util.Map bean that contains one or more parameter ids and corresponding values.

Hello All.
If I want to read in a file from a class which is
NOT A SERVLET, such as Action, how do I refer to it. Let me clarify
this. If it was a servlet I could have got the context, and from there a
relative path. BUT, from within a class there IS NO CONTEXT. For
example, I am running weblogic. When I search for a file without
specifying the path it searches from the "weblogic" directory, the place where I
ran the startup script. I only know this to be true because after 1000
painfull attempts it finally loaded my xml file from that directory when I
placed it there. How do you refer to a file from within a non servlet
class? Here is my code to refer to the file I want to open:

Am I missing something here? Ryan The key issue is that the two objects have different purposes. Organization is a data access object, representing the real live information in your database. As such, you do not want to be making any changes to it unless you've validated that those changes are correct. There will typically be one Organization style class per different business object in your database, possibly with pointers to other business objects as well. OrganizationForm is required to be a subclass of ActionForm, and it is really part of the view layer of an MVC architecture. It's primary purpose is to be able to reproduce the input that the user typed, if validation fails and the user is returned to that particular input form again. Consider what would happen if you've got an integer property in your database object (not true with Organization, but very common in real life). The corresponding property type on your data access object would undoubtedly be an int. But you would *not* want to do this on your OrganizationForm bean. You want the property to be a String instead. Why? Consider that the HTML representation of the input field lets the user type anything they want, and say your user types 1A3. You want your form bean's validate() method to be able to catch this, create an appropriate error message, and -- when the user is returned to the input form again -- have the field pre-filled-out with 1A3 (exactly what the user typed). This is a standard user expectation based on the way GUI programs work, and web apps that violate this expectation will get low marks for user friendliness. Another consideration is that a data access object will typically contain properties for all of the underlying database information, while form beans need to have only the properties that are required for this form. Different developers take different views of whether a form bean should include all the properties (I tend to be a minimalist, and only define properties for the fields actually on the form), but having different objects that are not in the same inheritance hierarchy gives you the option to mix and match as needed.

Different versions of Tomcat are configured differently, but they certainly do write to files in the logs directory if you configure them to. For example, in Tomcat 4 you'll see an entry like this in server.xml: Logger className=org.apache.catalina.logger.FileLogger prefix=catalina_log. suffix=.txt timestamp=true/ which establishes that the default logger (unless you override it at a lower level) writes to files named catalina_log.-MM-DD.txt in the logs directory.

Subject: Multiple Forwards
Hi all,
I am a relatively new struts user, so if the question I'm asking has been
answered before, I appologize ahead of time.
What I'm trying to do, is create a framework integrated with struts that,
among other things, allows users to set up multiple forwards dependent on
the broswer type. This could be Netscape, IE, WAP browser, or others.
What I would like to do is something like the following in the
struts-config.xml file:
...
action name=test
...
forward name=success browser=IE path=/ie/test.jsp/
forward name=success browser=NS path=/ns/test.jsp/
forward name=success browser=WAP path=/wap/test.jsp/
...
/action
...
You can't have multiple forwards with the same name because they are stored
in a HashMap which uses the name as the key - so they will just overwrite
each other.
The reasoning behind this, would be to create an additional
attribute that
could be used by my framework internals that determines the browser and
calls the correct JSP for the user automatically.
Something like:
...
return myMapping.findForward(success);
...
Which calls into a wrapper class that I create and determines the
browser,
then calling the appropriate JSP as defined in the config file.
This makes
it very simple for the user, as he only needs to define a series of
'success's, and the Action code is simple as defined above.
Now, obviously, adding an additional attribute to the forward
above is not trivial.
Creating your own custom ActionForward is straight forward, but I don't
think it gives you much benefit.
Extend ActionForward and add the addtional properties you require.
/* CustomActionForward Class ** START **/
public Class CustomActionForward extends ActionForward {
private String browser;
public void setBrowser(String browser){
this.browser = browser;
}
public String getBrowser(){
return browser;
}
}
/* CustomActionForward Class ** END **/
Then you need to tell Struts to use your CustomActionForward.
In the servlet entry in the web.xml file add the following init-param
init-param
param-nameforward/param-name
param-valuemyPackage.CustomActionForward/param-name
/init-param
Then in your struts-config.xml file use set-property to initialise your
addtional properties:
action
forward name=ie_success path=/ie/test.jsp
set-property property=browser value=ie/
/forward
forward name=ns_success path=/ns/test.jsp
set-property property=browser value=ns/
/forward
forward name=wap_success path=/wap/test.jsp
set-property property=browser value=wap/
/forward
/action
Obviously this is not very elegant and I you probably won't want to do this.
So my question, is has anyone seen anything like this, and is
there a way I haven't thought of to do this within the current struts
framework?
One thought I've had would be to do the following:
forward name=ie_success path=/ie/test.jsp/
forward name=ns_success path=/ns/test.jsp/
forward name=wap_success path=/wap/test.jsp/
This would work and not require many changes to the framework,
but I would
rather not do this, as it would make things very difficult for my
users to create their own actions.
Personally this doesn't look any more difficult for you user than what you
are proposing below.
Another possibility is the following:
forward name=success path=test.jsp /
browserforward name=success browser=ie path=/ie/test.jsp /
browserforward name=success browser=ns path=/ns/test.jsp /
browserforward name=success broswer=wap path=/wap/test.jsp /
In this case, I would need to create another XML entry that kept
all of the
'success' forwards for each action in its own little HashTable, much like
the normal forwards, except keyed by a combination of the name and the
browser attributes.
I honestly don't know how difficult this would be, but it seems like the
best solution I've come up with so far. One obvious drawback to
this one is
that the struts DTD would need to be altered to include the
'browserforward'
element. I am not sure of the implications of this.
It would be a pain every time you took a new release of Struts - I wouldn't
do this.
Any thoughts?
If you don't mind the constraints it imposes how about this for a solution:
For forwards which are browser specific create your entries in
struts-config.xml as follows:
forward name=success path=/$browser$/test.jsp/
Then in your action you need to do something along the following lines:
// Determine the Browser being used
String browser = ?
// Get the ActionForward
ActionForward origForward = mapping.findForward(success);
// replace /$browser$ in the path with the browser

Radio bution Question = How can I change the radio button name?
Hello - I am writing a page that has a dynamic list of questions that require radio button responses. In my actionform, I am storing the list of questions in an ArrayList of QuestionAnswer objects. These QuestionAnswer objects are basically the id of the question, the text of the question, and the answerId. My jsp code looks like this: html:form action=/answerQuestions.do table tr td align=centerQuestion/td td align=center colspan=3Answer/td /tr logic:iterate id=item name=questions scope=request property=questionAnswers type=com.company.QuestionAnswer property=questionAnswers tr tdbean:write name=item property=questionDesc//td tdhtml:radio name=item property=answerId value=0/n/a/td tdhtml:radio name=item property=answerId value=1/yes/td tdhtml:radio name=item property=answerId value=2/no/td /tr /logic:iterate /table html:submit/ /html:form So, I basically iterate through the list of questions, and it works, for the most part. The problem is that the html:radio tag uses the property name as the radio button name, and there seems to be no way to override this. So the html code ends up looking like this: tr tdQuestion 1:/td tdinput type=radio name=answerId value=0no answer/td tdinput type=radio name=answerId value=1 checked=trueyes/td tdinput type=radio name=answerId value=2no/td /tr tr tdQuestion 2:/td tdinput type=radio name=answerId value=0no answer/td tdinput type=radio name=answerId value=1yes/td tdinput type=radio name=answerId value=2 checked=trueno/td /tr tr tdQuestion 3:/td tdinput type=radio name=answerId value=0no answer/td tdinput type=radio name=answerId value=1 checked=trueyes/td tdinput type=radio name=answerId value=2no/td /tr So, instead of getting 3 groups of 3 options, I am essentially getting 1 group of 9 options, because it is using the same name over and over again. Is there any way to overide the name value for the radio tag? It does not seem very flexible to me, is this an oversight that may be fixed? Would my only option be to write my own custom tag that extends the functionality of struts html:radio tag? Or possibly I should rethink the way I am storing the questions in my actionform?

Proposal to add indexed to tags for Grid/Matrix-type use of Struts
Hi everyone. I have been working on adding the new functionality of the iterate tag (the getIndex() method) to relevant tags to allow me to refer to each of them in each row in a table ie creating indexed names such as name=myCollection[i].myProperty (search mailing list for Grid or Matrix for further ref). I have had good success by simply adding a few lines of code to the BaseHandlerTag.java which gets the index of the collection being iterated over and creates indexed names, if indexed=true is added to the tag. eg html:text name=parameter property=value indexed=true/ produces input type=text name=parameter[0].value value=Mac etc. This works great for the html:text, html:hidden etc that extend BaseFieldTag. It is a simple matter to add the functionality to Button, Cancel, Checkbox etc.. Note this is somewhat different to code Jeff Trent posted, in that the index is NOT specified, but is derived from the iterated collection directly. It also adds functionality to the regular Struts tags, rather than creating another set of Indexedxxx tags (though, I made reference to Jeff's code, along with Martin Cooper's!) I would like to propose these simple change are made to the Struts tag (though probably not for 1.0!!). It seems to me that are pretty clean, and would make a big difference to the above type of usage. If anyone would like to view this code, please let me know (although it will be next week now, as I am off tomorrow - yippee!!). Cheers, Dave

Steven, Since you asked about what frameworks compliment others Expresso Framework for example is being integrated with Struts so as to complement Struts. We're a lot closer with this integration with the release last week of Expresso 3.1.

We have forums on both our User and Developers Forums discussing this integration.

Out of Memory Errors?
This occurs when a very large query is performed. Anyone know of a way around this? Weblogic Output: ; nested exception is: java.lang.OutOfMemoryError: Start server side stack trace: java.lang.OutOfMemoryError
How can I use an Iterator's value twice?
This problem loosely related to a couple of others that I've seen recently on this list, and it's a common enough thing to do that there must be a simple solution that I just don't see. I want to produce a list of search results as hyperlinks in which each list value is displayed AND is used in the link, as in: ol lia href=/myapp/fetchItem.do?key=key_1key_1/a lia href=/myapp/fetchItem.do?key=key_2key_2/a lia href=/myapp/fetchItem.do?key=key_3key_3/a ... etc ... /ol I've tried using the iterate tag and a bean that has an Iterator property, along with html:link as in the following sample: logic:iterate id=results name=mainSearchBean property=resultsIterator li html:link page=/bookDetails.do paramId=key paramName=? paramProperty=? bean:write name=results/ /html:link /logic:iterate I've tried setting paramId, paramName, and paramProperty in various ways but nothing gives me the results I want. The best I get is a list of hyperlinks for the results as expected except that the actual links are all the same. I also tried jamming a copy of the bean:write name=results tag in the page attribute of html:link but that caused an exception. Should I just add a Map property to mainSearchBean and, if so, how would I use it to this effect? Thanks. - Mark.
Beans shouldnt return values (my collegues argue)
My 2 collegues argue that the ActionForm (or any bean) should not return values. They argue that if some day they decide they want to insert a service between the Tag and the Bean, it would complicate things because the inserted service would be forced to return the Beans object to the Tag: BEFORE TagBean AFTER TagServiceBean If the new service wanted to return an int it couldnt because the Tag is expecting a bean. I truthfully dont know the upside or downside to this, and I personally am not opposed to returning an object. They would like that the bean throw an Exception instead. Could you all comment on this as I do not see a problem with a Bean returning an object

Weblogic Output: ; nested exception is: java.lang.OutOfMemoryError: Start server side stack trace: java.lang.OutOfMemoryError It means you are out of memory :-) What happens is that when the JVM is started, it has an upper limit on the total amount of memory it will allocate on the heap for Java objects. If you try to create more objects than you have room for, you get this exception. Typically, a JVM will support command line options to change the default memory maximum (typically 32mb or 64mb). With the standard Sun JVM, for example, you do this with the -mx command line option. Weblogic's startup scripts might have some documented ways to do it from the command line, or from a properties file, or something like that. Craig
