RE: Unit Test in struts
Maybe I am not smart enough for my applications (order entry, inventory,
etc.)
I just don't see how to give any real functionality in the
application space without JavaScript.
Some issues where I don't see a work around for which are intrisic
to all the applications I am working on.
1) The user is entering items. User needs dynamic
feedback as to to how much is entered so correctness
of data entry can be determined.
2) User can't remember a code from a 'large' list and
needs to look it up and return to where he was with
the correct value filled in. Perhaps it can be done
with some fancy footwork with actions but...
3) Menus, yes there are plenty of static menus but
all the real ones are javascript, i.e. coolmenus
cannot be tested with the existing test tools. Menu's are
not required to be tested but it would be nice.

RE: Session Problem
If IE opens a new window (either through javascript or from the
file/new/window menu) and IE is in a session, the session is shared between
the two browser sessions.
If you open two copies of IE from the operating system, they will not share
the session.
The only way to solve this that I know of, is to keep a session token, if
you find it out of sequence, forward to a page which closes the window (if
javascript is enabled). If you use tokens on your update sequences you
should be able to live with the two browsers in the same session.

Subject: RE: Session Problem
I had a similar problem.
I have two browsers opened with diferent sessions (and logged on with
different users to my app) in the same machine.
In one browser, I click a button that opens a new window (window.open in
javascript) and in this new window a submit is performed to an action of
struts. This action has an execute that checks isTokenValid and gives
false, not because I haven't saved token first, but because session are
different.
*/
protected boolean isTokenValid(HttpServletRequest request) {
// Retrieve the saved transaction token from our session
HttpSession session = request.getSession(false);
//-- here, session id is different of the main window
session, but equals to the other window session.
if (session == null)
.
.
.
//as session id is wrong, token is invalid.
}
If I have one only main browser opened this problem doesn't happen. I
think that it can be a window.open IE problem, but I still couldn't find
out a solution.
If anyone has one...

You can take a look through all the browser options and see if there is
anything to make it associate cookies only with a specific window, but I
would be quite surprised if there is such an option. I suspect in the
absense of url rewriting you will need to use either different machines
for each browser, or a different browser (ie open second window in
mozilla or something). Hopefully Im wrong on that and someone else on

On the same machine? Rather sounds like its the same session. Im not
sure about IE6, but as I recall, IE5 will share its cookies between the
various windows if cookies are enabled. If cookies are disabled then url
writing takes over (asuming youve made sure your links are re-written by
using the appropriate tags) which means they shouldlnt share sessions if
opened seperately. You could test this theory by disabling cookies in
your browser and see if it makes a difference.
Put it a log statement somewhere to log the sessionId and compare the
results for both the windows to see if it is indeed a different session,
or if the second window causes the first window to end up in the
second's session.

If you use those, you'll likely get the re-writing you're looking for. I did this on a previous project and did find that the forward attribute worked, but not the action attribute. I believe this is a bug in Struts since it should do rewriting when looking up an Action's path. The one issue with re-writing is that if you're using a menu that matches URLs (i.e. tabbed-menu) - they probably won't get matched up. At a previous project, we were using URLs to highlight the current page we were on and we found that we had to use the action attribute or the page attribute so that the jsessionid wasn't appended. Of course, we could've stripped this off in our Velocity template, but we wen't with the quick, less-logic, way. To see this project, go to http://telluride.resortquest.com and drill down a bit. The menu with highlight is on the right. BTW, this site uses the Velocity displayer for both the top menu and the side menu.

The current struts datasource is deprecated and it is recomended that you use either a jndi datasource or a product like poolman on sourceforge or a DAO product which maintains the datasource itself. I suspect your problem is due to not including struts-legacy.jar since the datasource is only marginally supported and was not included in the base jar.

filters / tomcat / httpunit / webtest
I have a an interesting issue which at first blush doesn't seem solvable but could be a bug in struts 1.1 or my use of struts. I have a partially implemented struts application which is using filters for security (not the sourceforge security filter). I used to issue a 401 error, have the container trap the error and forward to the logon page. That worked fairly well with tomcat 4.1.18. I had a testsuite in Struts-Test, HttpUnit and WebTest which was working reasonably well. I updated to tomcat 4.1.29 which passes the http 401 error to the page, with the actual login page. This causes failures in HttpUnit and WebTest which assume a 401 error is a Basic Authentication Error. I thought about throwing / catching other errors but have not completed tests. The sourceforge security filter just does a RequestDispatcher forward to the login page. This works fine on straight jsp pages. However on struts pages there is some additional processing and something (I have not yet figured out) from struts gets put in the response so that there is an IllegalStateException thrown when the filter performs the forward. Additionally, response.redirect has the same issue. The only struts log messages have to do with PropertyMessageResources, which are not there for both straight JSP and struts resources. Does anyone know what in struts could be writing to the response or where to start looking? Thanks in advance. Edgar --- Outgoing mail is certified Virus Free.

RE: [OT] Canoe Webtest / HttpUnit
Thanks for the article. Something about the update from 4.1.18 to 4.1.29 caused my cookie test javascript to give inconsistent feedback in the HttpUnit javascript. I tried another algorithm and worked past the error. BTW for you test junkies, if you used web.xml error-pageerror-code to trap http errors and return a different page, tomcat 4.1.18 doesn't pass on the http error with the page redirect while 4.1.29 does. Tests of pages which take advantage of those automatic redirects will start failing when you do an upgrade. Thanks again.

RE: Design Questions
-Original Message- From: Scott McClure [mailto:[EMAIL PROTECTED] Sent: Saturday, January 03, 2004 10:50 AM To: [EMAIL PROTECTED] Subject: Design Questions First, I was thinking about using a single UserForm to validate all forms relating to a user, for instance. The problem is, is that some fields would not be necessary for update actions and their validation code would throw a ActionError with the default value. I could use conditional validation in the ActionForm based upon the ActionMapping, but that would create ties between the config file and code that I am not sure I want to make. What is your opinion? In your load action, always fill out the entire form. As long as you session based form beans and don't use the reset (for checkboxes) the data will pass without input fields in the jsp. Next, I am trying to tackle the problem of the granularity of my Action objects. At first, I thought about using a DispatchAction, but that only allows me to use one ActionForm for all of the Actions in that class. Then, I thought that maybe wildcards would solve my problem. Wildcards, though, seem like a security concern, where it would be theoretically possible to run an action that is not intended to be run (to exploit any handling errors). Also, I am not sure if that solves any granularity problems, but merely simplifies configuration in the config file. Are there any other good solutions for solving granularity problems? Did I mis-understand DispatchAction? General comments on security with wildcards would also be very interesting. I am a believer in standard actions and have your business classes implement interfaces for the actions to use. So in the save/update/delete sequence you have a single action which calls standard functions in your business classes. Also, slightly off-topic of my previous questions, what naming conventions do people use for application messages? In struts I have seen a general format of prompt.*, heading.*, and using page specific messages under the page name. What are some suggestions? I want to resolve to a naming standard now so I dont have to go through and change everything if it becomes a code managibilty concern. If you can name them package.class.messageKey or url.field.messageKey it works well as well.

RE: Server manged vs. struts managed db pools
There is another issue regarding connection pooling in struts vs connection pooling in the container. In struts the war file contains all the information the app needs to run. With container pooling (at least with tomcat and resin) you have to coordinate the container configuration with struts configuration. With a single container running multiple apps this is a bit of an issue. Edgar -Original Message- From: Craig R. McClanahan [mailto:[EMAIL PROTECTED] Sent: Monday, November 24, 2003 11:03 PM To: Struts Users Mailing List Subject: RE: Server manged vs. struts managed db pools Quoting Edgar P Dollin [EMAIL PROTECTED]: I like struts managed db pools, however, the struts developers aren't too happy about the quality and the dependency on the commons-pooling library and are attempting to phase it out. The existing connection pool in struts-legacy.jar (and the one in commons-dbcp.jar nowdays) works fine. However, there are several important pros for using container managed connection pools: * A connection pool implementation provided by your app server is likely to be optimized for better performance on that particular app server than a generic pool included with the app. * A connection pool implementation provided by your app server is likely to be supported by the graphical admin tools of that app server, versus having to be hand configured in struts-config.xml. * On some app servers, you can dynamically tweak the characteristics of the connection pool (such as how many active connections are allowed) without restarting the app. That's not the case for a pool included inside the app, where you have to go tweak struts-config.xml and restart. * A connection pool provided by your app server vendor is accessible (via JNDI) *anywhere* in your application, versus having to be passed in as a parameter to any method that needs it (or making your business logic dependent on the servlet API in order to access application scope attributes). * In environments where you have two or three different deployment scenarios (say, development, test, and production) you can deploy exactly the same WAR file in all three places, yet have each of them talk to the correct database simply by administering the server. No tweaking of the struts-config.xml file to reflect which environment you are deploying to. The only reason Struts ever included a connection pool in the first place is that most standalone servlet containers at that time didn't support JNDI-based pools. Now, that is no longer an issue, and I would always recommend using the container's facilities for that purpose.

RE: Types supported by DynaActionForm (or DynaValidatorForm)
There is some contradiction when it comes to types in ActionForms. The
general idea of struts is to put a bunch of Strings (or booleans) between
the application and view layer so that after unsuccessful validation the
framework can return the typed values unchanged. In certain cases,
individual developers put in support for types other than Strings for
certain features.
The bottom line is, until there is more concensus on the use of data types,
use non String ActionForm properties at your own risk.

OK, in the Struts manual, it says:

What does supported mean though?
Cause if I try to specify a java.sql.Date field in my form in

And upon searching the archives, I found suggestions to use

So what does support mean? Is there any automated
(non-custom) way to do this, so I can just say (Date)

RE: Server manged vs. struts managed db pools
I will speak about tomcat since that is the one I have used most recently. The web.xml file which is in the war file has a reference to the JNDI objects created by the container. Say you have the same application deployed multiple times (one for each customer). In my application(s), each customer has a separate physical database which means that you have to mess with server.xml in the web container configuration to add the additional database for each customer added (not really an issue if you are adding context elements for virtual servers). Additionally, you don't need a configuration parameter in your application for the JNDI database handle as it can be hardcoded and only change struts-config.xml to reference the correct database. http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-datasource-examples-how to.html Edgar -Original Message- From: Vic Cekvenich [mailto:[EMAIL PROTECTED] Sent: Tuesday, November 25, 2003 6:17 AM To: [EMAIL PROTECTED] Subject: Re: Server manged vs. struts managed db pools Edgar P Dollin wrote: There is another issue regarding connection pooling in struts vs connection pooling in the container.

RE: Token documentation
I haven't seen any but there isn't really much to document. You put an integer into the form with a value that is updated by the action. This value must change from request to request, typically it is incremented. You must carry a hidden field in the jsp to carry the token to the following request (if you don't have the hidden field and are using session beans the value will always be correct, with request beans it will always be incorrect). The load action also puts the token value into the session so the next action can check the value. When the target action is invoked, it picks up the token and checks the value against the actionform. If the value is not the same, i.e. the user hit the back button and resubmitted, you have an error situation. You can forward to an error page or take whatever action you deem necessary at that point.

So here goes again: The thing I've been looking at Internationalization issues concerned with Struts. The thought of being able to change the whole language of a site simply by changing the locale of the user really appeals to me. All examples i've seen so far use parallel versions of the ApplicationResources.properties file to accomplish this. Whilst this may be feasibel for a fairly small site I don't see how this solution would hold up for a large site (with serveral hundred concurrent requests to anyone of several thousand pages). The problems/questions I can see are: As a single textfile is used, when there are several thousand entries it will become difficult to manage. Can updates be made, during operation, to the content ? What happens if a user requests the files content while it is being edited ? Is the textfile cached for performance, or will concurrent calls compete for the same file-resource ? As I'm probably not the first person who is trying to use Struts on a larger scale for internationalization issues I thought someone might have a better solution.

RE: Tags creating Tags
There is a little more overhead than this. You are now taking control of the struts tag lifespan. Currently, assuming tag pooling, this is done by the container based on a hash of the parameter values. If you are careful you can piggyback on that by synchronizing the internal tag instantiation with your tag. You could instantiate the internal tag on every reference, but that would be a step back in terms of efficiency. Then any jsp parameters you will be passing to the internal tag must be passed prior to invoking the tag. Additionally, each of the methods of the Tag or BodyTag interfaces must be implemented and call the internally referenced tag based on the requirements of the tag. Most of the struts tags don't have a 'real' body so this is not that important. If you were considering wrapping the iterate tag, you would have an interesting problem.

RE: struts-menu
Stuts menu can do all of that. Be prepared to write some customizations since there are inconsistencies in the capabilities between the menu displayers.

Edgar -Original Message- From: Adam Hardy [mailto:[EMAIL PROTECTED] Sent: Thursday, October 23, 2003 6:26 AM To: Struts Users Mailing List Subject: struts-menu Hi All, I am writing the menu part of my app right now and I have basically made us of tiles-def.xml to specify what links I want in each page, which seems a very handy way of doing it. In my menu Tile I have a couple of links as well that will always appear and vary depending on whether the user is logged in what role they have. Then I remembered that there is a struts-menu add-on at sourceforge, which I checked out. I was looking for anything that I might have forgotten that could pop up later and bite me. Obviously it wasn't exactly possible to find such unknown info, so I thought I'd list my menu requirements here and see if any can tell me that I've forgotten something important. Basically the site is a small e-commerce outfit selling webservices. My menu is meant to be / do the following: (1) a run-of-the-mill list of context relative links (2) no javascript (3) several permanent, static links, e.g. home, about, contact (4) several permanent toggling links, e.g. register or login or logout (5) several context sensitive links, e.g. to other components of the site That seems to be it AFAIK.

My preference is to emulate the session functionality in your own classes, i.e. publish / subscribe. Stick a static map in your class and use a unique key generated from objects both threads are aware of to index the object, then you can pull it out when you need to. Synchronize if you need to as well. I like this better because then you can run junit tests w/o worring about the container.

My ISP is pretty irate because we suck up huge amounts of CPU each time it happens. We are using Tomcat 4.1.24, Java 1.4.1 and Struts 1.1. OK, the page uses a couple of nested foreach loops to generate a grid/chart of SVG markup language. It also uses a couple of small foreach loops to generate tick marks on an axis. It looks something like: Chart page embed tag include JSP/JSTL page to generate footer. include JSP/JSTL page to generate x and y axis JSTL markup to generate main body of chart include JSP/JSTL page to generate footer. The request takes a half second to build the Java objects that the JSTL code uses to render on the page. But the rendering takes 45 second on a 650MHZ Sun SPARC III machine and almost that long on a fast Windows machine (2500 MHZ). The second and subsequent times the chart rendering drops down to less than 200 milliseconds. Then about five minutes later, if the chart is requested again, it takes the 45 seconds to generate, then 200 milliseconds for subsequent requests.

RE: Errors / Messages
I would like the action to perform (not fail as validator specifies) but give feedback to the user about the entered data. For example in certain fields you can use a table as a select but override the selection, and other input would be added to the selection. You would want to let the user know that the information was added to the allowed list. I am doing your other selection in the action class as well. My intermeditate solution, is to extend the ActionForm and add an informational message ActionMessages property and a special tag for displaying any pending informational messages. Edgar -Original Message- From: Max Cooper [mailto:[EMAIL PROTECTED] Sent: Monday, September 15, 2003 5:38 AM To: Struts Users Mailing List Subject: Re: Errors / Messages Edgar, What is your aim in doing this? If there is a validation error, the Struts framework sends the user back to the input page to inform them of the problem, and possibly allow them to fix it and resubmit. If the request still gets passed to the action, the action will need to do conditional processing based on the presence of errors, and then it is unclear how control will pass back to Struts so that it can send the user back to the input page to inform them of what went wrong. I have sometimes thought about having the action produce a validation-style error if something goes wrong in processing the request, after which it could pass control back to the Struts framework to send the user back to the input page. You can of course add another forward or something, but it would be nice if you could just tell Struts more cleary that something went wrong and that Struts should send the user back to the input form (as it does with a validation error), but I am not sure if there is an elegant way to do that. This is distinct from your proposed flow, but it seems the same feature (tell Struts there was an error and user should be sent back to input form) could support both of our scenarios.

RE: How to reference multiple form beans from one VelocityLayoutS ervlet set of page fragments?
I have gotten two html:forms two work in a limited fashion with struts. Note that your always visible form, doesn't have to be connected with a struts action so the problems with actions wouldn't apply. Also, the rules for forms are different if you are using tiles since each tile has an action and I believe tiles works with Velocity.

RE: Migrating to struts
This would depend how your application was architected. If you do ONLY jsp (i.e. sql and logic in the page), then basically you are re-writing the application by cutting back-end code out of your jsp pages and creating business logic classes and action class. If your application is reasonably well architected, then you are probably going to be creating DynaForms in xml and on each jsp replacing validation logic, message logic, etc to utilize struts features.

RE: Struts custom tags tutorial
In the case, the user described below, I didn't. What he wanted to do was, based on data values, guarantee a color scheme and other criteria, i.e. maybe all negative numbers should be in red. This is view based logic, but one of the priciples we all use is try not to write the same code twice. I might be missing something but, JSTL, and most view technologies (except custom tags, source includes and tiles), don't have the ability to modularize common code or have strange syntax to achieve the modularization. So to say just use the standard technologies and let the view have the view logic is a bit of a cop out. I suspect that most of what he wants to do is already in struts-layout so there is a work around without writing his own tags.

Subject: Can an INPUT tag know its form name? Also, application
resources...
In writing a taglib for my calendar popup, I've come across two
questions:
1) I need to write javascript which references the generated input
tag. To
do this, I need to know the name of the form that it is contained in to
get
a javascript reference to it. If no form name is found, I'll default to
form
[0]. This isn't working:
protected String getFormName() {
// Acquire the form tag we are associated with
FormTag formTag =
(FormTag)pageContext.getAttribute(Constants.FORM_KEY);
if (formTag==null) {
return 0;
}
else {
return '+formTag.getName()+';
}
}
I took this from the html:option tag as an example. Is this not
possible
for the form tag?
2) I have a .properties file for my taglib which defines standard text
and
default options. It would be great if a user could over-ride those
settings
with messages in their own application-specific MessageResources. Is
there a
generalized way, in my taglib code, to get a reference to the
application's
message resources so I can search for keys that over-ride my defaults?
The other option I thought of is that the developer can extend my taglib
with their own and point to their own MessageResources file, but this
isn't
as slick.
Any other options?
PS: Just have to clear up these two things and write more examples and
it'll
be ready for testing...
Thanks!

RE: Suggestions for Calendar Popup taglib?
I love your tag libraries and have used most of them. It is very generous of you to have donated them. One of the problems I had with some struts tags, i.e. html:options, is that there is a repetitive download of the same text. In large pages, especially nested pages, the size of the html becomes excessive, which of course is aggravated by the tendency of struts to force reloads for validation. This problem is repeated in the validator with the same javascript being downloaded multiple times (one reason why I don't bother with validator). When I modified the struts tags to use your libraries, I created separate .js files which were loaded only once. I assume that the struts committers will not want to distribute .js files so when you are putting together your your tag could you keep track of emitting the javascript and do it only once per page. Also, I have some old databases I access which use non-standard data formats. Could you have an optional property to a class/method which would convert the text to a java standard format. Of course you could assume this was a reentrant singleton class and you would only load it once.

If they aren't faster in performance then something is wrong. All the JSP rendering practically has to do is put the code as is into the Servlet which is a Java class. No interpretation. I haven't looked at the source but I am sure the optimization for rendering code for Scriptlets vs JSTL has to be there. Don't be so sure. Because the JSTL is standard, containers can optimize the java code generated from JSTL tags. This means a c:if tag can be converted into a real Java if statement instead of creating tag instances and invoking the tag's lifecyle. My understanding is that the Jasper JSP compiler (comes with Tomcat) actually generates faster Java code if you *don't* use scriptlets at all. Resin and Tomcat both optimize JSTL tag usage. So, with the JSTL we get the best of both worlds: Fast page rendering and standardized, powerful and easy to use markup tags. David __ Do you Yahoo!? Yahoo!

RE: [OT] RE: JSTL ot struts taglibs?
You are not alone is questioning the solutions to the view problem. This is an interesting problem and will really challenge the open source community to solve it. Right now, everyone has an opinion, no one has a real solution, each individual users needs are limited (they tend to solve their particular needs and move on) and the problem is EXCEPTIONALLY complex. Part of the problem is that there are so many ways (none of which are particularly good compared to .NET) to paint pages in Java land. JSF is vapor and has a limited window of opportunity and requires REAL industry support to succeed before the world moves past it. .NET view technology looks really tempting from the outside and there are statistics which support that it enhances developer productivity (this will have a greater importance as time passes). The individual with the most influence in the space is Craig, which is why JSF is seen as an overall solution. Unfortunately, many in the community disagree with him and with JSF. I wish, I agreed that JSF was the answer and that if we all jumped on the JSF bandwagon, the industry could move past this problem, we could have great IDE's for view creation, etc. Anyway, this is a real challenge facing the community with very strong pressure being applied by MS.

-Original Message- From: David Graham [mailto:[EMAIL PROTECTED] Sent: Wednesday, August 13, 2003 9:53 PM To: 'Struts Users Mailing List' Subject: Re: Some questions for you guys... I prefer configuring a DataSource in the servlet container and retrieving it via JNDI. This way the app knows nothing about the configuration except for the JNDI name the DataSource is stored under. One of my requirements is that I have a separate DB for each of my customers. Each customer is using the same container instance but needs access to a different DB (the data has to reside in separate DB's). This can be done in a JNDI situation but then the container configuration has to know about each web app instance and each web app instance needs to know about a separate JNDI configuration.

RE: Urgent: generating PDF from form data
Have you looked at iText? Another one to try is JasperReports (Jasper uses iText) but also uses POI to optionally generate XLS or HTML.

RE: transaction tokens
I have implemented and it works OK, the user can have multiple windows open and within reason use the back / forward buttons. The problem is what do you do if they backup and then take a different action. You need to have some way of recovering the path in a graceful way, without the user loosing to much of the information they may have typed. Edgar -Original Message- From: Adam Hardy [mailto:[EMAIL PROTECTED] Sent: Wednesday, August 06, 2003 5:41 AM To: 'Struts Users Mailing List' Subject: Re: transaction tokens I was thinking there might be a way of controlling transactions by saving all tokens in the session once they are used, and then if it crops up again, not allowing the execution. Would be simple to implement with a hashmap I think. What's the likelihood of 2 transaction tokens being identical, over the course of a user session? (Theoretically you could apply the same principle to action forms,saving them against a transaction token and then sorting it out in a base class during form.reset() (exceptionally seat-of-pants thinking)) Andrew Hill wrote: oops, yep. Should have specified that. Only for a session mapped actionform will there be a problem.

RE: Garbage Collection Problem with Write Tag
The JSP specification allows Tags to live independent of the pages they are declared upon. As far as I know it is up to the container as to when they are garbage collected. Some containers optimize the occurances of the tags based on the parameters passed to the tags, i.e. declaring a new one for each unique set of parameters.

I observed some of the strange things. After executing a action I am displaying a set of records in a Grid (50 records). I tested this application by using WSAD Profiling. In the profiling results, I seen 120 live WriteTag instances(which is not garbage collected), same thing I observed for Radio Tag also. Can any one help to make these objects as garbage collected. Pls check the attached screen shot of the results. The filled color shows the objects which are not Garbage Collected.

Vic gave a very interesting Flash demo the other day. Considering the poor state of java view options it was good to see a real alternative to the gobbledygook currently available.

RE: Testing Struts-Config
An additional useful test would be whether all the referenced classes actually exist in your webapp (form beans, actions, ...). Of course, that probably ought to be a configurable startup feature for Struts itself. This would be perfect...if you need any help let me know. -James Craig Edgar - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Testing Struts-Config
Does anyone know of a tool that just tests the struts-config for 'class correctness'? The situation I find myself in is I have a large project, which was heavily refactored (unfortunately w/o adequate struts tests), and I need to debug the struts-config. Thanks in advance.
