RE: How to return changes made on a JSP iteration of object properties to the Action Class
Hi , First when you set the arrayList to the form bean and use struts iterate tag then you can display the result. When you want to reconstruct the ArrayList back you need to write String[] , int[] or long[] data memebers and getters and setters methods in you form bean. Struts does not call setArrayList () method on the form bean when you submit the page. Form these you need to reconstruct the ArraryList it is better to do in the Action Class.

DynaValidatorActionForm - List - nested:iterate: TROUBLE
Hi, I'm exploring the new features of Struts 1.1 (using b2 release) and got stuck on the use of the combination DynaValidatorActionForm - List - nested tags (iterate, write). CASE I am trying to build a search list page. The search is a form with (for simplicity) one 'html:text' input field and a search button. The results of the search need to be displayed on the same page and be part of the same form. This list of results will be displayed as: a checkbox in the first column and a range of properties of the objects (e.g. Books) in the resultset in subsequent columns. The user will be allowed to select multiple items from the list for further processing. Think of a list of books, the user selects the books he/she wants and they are added to the shoppingcart. I would like to use a DynaValidatorActionForm with form-bean properties 'title' (java.lang.String) and 'books' (java.util.List). The search action handler uses the input from the title field to fetch the books from the database and sets this list of books in the 'books' field of the DynaValidatorActionForm. PROBLEM Doing the first search and display the results is no problem but on a new search request, the form can not be processed. I get a java.lang.NullPointerException: No indexed value for 'books[n]' (n being the size of the resultset of the first search). What could be the problem? -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

RE: Disabling jsessionid parameter in Struts forms
You are correct about encodeURL() - this is when the sessionId is appended. The sessionId is part of the servlet API session tracking mechanism , and as you have noticed is appended to the URL when not using cookies. (When using cookies it is instead stored in a cookie). If you do not include the sessionId , you will not be able to make much use of session scope in your website (as each request will get a new session). If you dont need to use session scope to keep track of anything, this probably won't be a problem (I think - unless struts itself needs it for certain things?). As for actually disabling the appending of sessionId I am afraid I have no idea how you might achieve it with regards to the struts tags. -Original Message- From: Ori Tend [mailto:[EMAIL PROTECTED]] Sent: Thursday, September 26, 2002 17:59 To: 'Struts Users Mailing List' Subject: RE: Disabling jsessionid parameter in Struts forms Thanks for the reply!

Struts and high performance sites revisited
Ok, so we got it nailed down these statements... - The Struts Controller doesn't add more overhead than a high performance site should be able to handle. In the regard flexibility contra performance, using the controller makes your application manageable with negligible overhead. - There was also the everlasting discussion on EJB's be or not to be. I think that there are loads of variables that affects the choices of the design and that there still remains some issues with EJB's. However when only using stateless session beans with DAO's I think that the scalability-flexability-performance goes hand in hand and makes a preferrable design choice. Anyone disagrees? Would be nice to hear your opinions. - But what was not discussed was the overhead of custom tags. This seems to be a question much avoided everywhere. When talking about flexability. Oh yes, use them. They makes your pages much easier to build and manage. They also makes for a great design of the application. BUT (capital letters), what about the performance overhead of the tags?

Re: Scheduled Jobs
Hi, you may define some thread to be started while the app init process. Works nicely for us. Two classes are required. 1. Simple init servlet that will be plugged into web.xml (similar to the way that struts action servlet is plugged) In the 'init' method you could start your thread daemon. You could also pass some parameters this way. Stop the thread in the 'destroy' method. Because this solution works with threads, I would advise to put some flag there if it has already been started or not, to make sure there is only 1 instance of your thread. 2. The thread class. It could be parametrized (see above), for example JNDI resource name for database, interval, etc ... We sceptic about such solution, but it really works nicely when we tried it. Another solution. You could create some servlet that does cleanup job, and periodically call it with cron. I would advise 'curl' as your http client - works on Unixes and Windows. It's very nice, free, single file program. That solution is platform dependent, ie. different way of configuring cron, and different versions of your http client are required. Is anybody using different solution?

RE: Value selection
Mohan, One way to do this is to have your action form contain the Collection of options which you wish to display and an array of Strings which represent the values selected by the user. The Collection of options could be a collection of LabelValue beans. Using your example we would have the following in the action form: Collection applicationOptions; String[] applications; You could use the following syntax to render your application options: html:select property=applications multiple=true size=2 html:optionsCollection property=applicationOptions label=label value=value/ /html:select If applicationOptions doesn't change over the life of the application, then you could initialize this collection at application start up and place it in the ServletContext where it would be available to all users. If you do this there a a couple ways in which you could retrieve them. 1. You could have a set up action populate the action form with the applicationOptions that exist in the ServletContext. This way you wouldn't have to manage a separate attribute key for the applicationOptions. 2. You could simply use a separate attribute key to store and retrieve the applicationOptions from the appropriate scope. robert -Original Message- From: Mohan Radhakrishnan [mailto:[EMAIL PROTECTED]] Sent: Thursday, September 26, 2002 6:30 AM To: 'Struts Users Mailing List' Subject: Value selection Hi, Is it possible to display these values from a bean ?

RE: Struts and high performance sites revisited
a. Stateless session beans are fine until you need transactional boundaries to protect data integrity. If you want to improve performance of the app, design a persistent cache for immutable data (or data that rarely changes) to reduce trips to the data store. b. There is no overhead for custom tags except for the initial compilation of the JSP into an object. The only exception here is, obviously, you inundate a JSP with tags. Then you will get the same performance hit you get when having a class method with a poorly-design looping or conditional algorithm. Design, design, design.

RE: all this traffic
Note I removed the [OT]. :-) I think this is right on topic because there have been many complaints from all level of users about the difficulty of finding useful information in the archive. If the archive was better managed, list traffic could be substantially reduced. For that matter, just having the URL attached as part of the signature would probably greatly reduce traffic (and would remove the I didn't know there was an archive, or I didn't know how to find it excuses. But the idea of tagging questions and responses with some pre-defined elements is intriguing and certainly would add value to the archive. -Original Message- From: David Graham [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 25, 2002 7:59 PM To: [EMAIL PROTECTED] Subject: [OT] RE: all this traffic You get right to the point don't you Mark :-) ? I think online forums are much easier to use than mailing lists because they're easier to search for previous questions and you can easily ignore uninteresting topics. However, one practice I like is the use of [OT] to designate clearly off topic threads like this one. I filter those mails to a different folder for convenience; I wish more people used that convention. Ironically this thread is only increasing the amount of traffic.

It's a bit frustrating trying to use a high traffic mailing list like this one. Here are some suggestions: - Have a struts-answers mailing list. If I found a discussion interesting - such as the one on container managed security - I could simply forward it to the answers list. The cost of asking a question could be to compile the answers and submit it to the list. This could be a cheap way of getting better documentation. - A struts-beginners list might be a good idea too. Sometimes the blind are not all that bad at leading the blind. - One could also consider having a struts-tags list. With JSF coming, there are going to be more people that are not interested in the Struts tags.

Need Help Fast
This is not really a struts question but I am using struts a maybe someone
can help. I system has allot of state dropdown's so I I made a tag for the
programmers to insert into the JSP pages.
The Tag builds a ArrayList with the states in it and then saves the states
as a attribute in the pageContext. But I don't know if this is the best way
to do it. Is it anyway to tell this code only to run one time and then stay
in member?

RE: Struts and high performance sites revisited
Hi I've recently been struggling with performance issues related to tags, especially where there are large number in some of our pages. The biggest improvment we got was by switching application servers. Specifically by upgrading to the latest Tomcat 4.1.11. The difference in response is incredible. So it would seem that the major issue is with the type of code generated by the servlet engine. We spent some time looking at the generated code, the major issue being that every tag reference is created as a new object. There must be better way to do this. Until this point I was wrongly assuming that the tags were run as just method calls on one instance. will JSTL improve on this ? :-) Tom Lister * 020 7612 3030 * [EMAIL PROTECTED] -Original Message- From: David Zimmerman [mailto:[EMAIL PROTECTED]] Sent: 26 September 2002 10:43 To: [EMAIL PROTECTED] Subject: Struts and high performance sites revisited Ok, so we got it nailed down these statements... - The Struts Controller doesn't add more overhead than a high performance site should be able to handle.

RE: Need Help Fast
Hello,
One possible solution:
Put the ArrayList in application context and put a check in doStartTag()'s beginning
to determine whether the list of states can be found in application context.
Instead of:
pageContext.setAttribute(selectStates, states);
Put it like this:
pageContext.setAttribute(selectStates, states, PageContext.APPLICATION_SCOPE);
And in the beginning of doStartTag():
Object o = pageContext.getAttribute(selectStates, PageContext.APPLICATION_SCOPE);
if (o == null) { ...do what your current code does...
}
else { ...do nothing... }
But why do this in a tag at all? If your list of states never changes, you might as
well initialize it in an init() method somewhere.

Just added to validator, you can get access to the form from
a validation
rule by putting Validator in the method signature. For example:
public static boolean validateLastNameIsBob(Object bean,
Field field,
Validator validator) {
Object form = validator.getResource(validator.BEAN_KEY);
String lastName = ValidatorUtil.getValueAsString(form,
lastName);
if (lastName.equals(Bob) return true;
return false;
}
If you look in the unit tests for Validator, you can see a
requiredif
validation I wrote that does generic cross-field validations
(i.e., last
name is required if first name is filled in). I'll be
submitting as an
enhancement for Struts Validator soon.

Hello,
One possible solution:
Put the ArrayList in application context and put a check in doStartTag()'s
beginning to determine whether the list of states can be found in
application context.
Instead of:
pageContext.setAttribute(selectStates, states);
Put it like this:
pageContext.setAttribute(selectStates, states,
PageContext.APPLICATION_SCOPE);
And in the beginning of doStartTag():
Object o = pageContext.getAttribute(selectStates,
PageContext.APPLICATION_SCOPE);
if (o == null) { ...do what your current code does...
}
else { ...do nothing... }
But why do this in a tag at all? If your list of states never changes, you
might as well initialize it in an init() method somewhere.

RE: Struts and high performance sites revisited
Tom, I totally agree - its all in how the server gen's the code, for the most part. The rest is related to the spec itself and how much it allows app servers to optimize. There was a discussion about the thread safety of JSP tags a little while ago. Here is what I wrote up: http://www.mail-archive.com/struts-user@jakarta.apache.org/msg39324.html The reason I bring this email up, is that I have listed a section from the JSP spec where they discuss that a JSP tag should remain dedicated to the page: The JSP page implementation class instantiates a tag handler object, or reuses an existing tag handler object, for each action in the JSP page. This means that app servers *could* start pooling these tags to reduce the overall creation and garbage collection. I'd be interested in someone who would benchmark the differences using something that is open source (like Jasper), which could be quickly modified to use Doug Lea's object pooling or something similar and compared.

RE: Struts tags for display a collection of views [paging design pattern]
Paging is the good term to describe what I want to do. I don't work directly with a dataset because I use an back-end application server that works on the database. So I receive a list of JavaBean that I would like to display in JSP pages. I found a little description of the paging pattern but I would like to know if someone has created an application with paging that use Struts tags (logic:iterate) or nested tags. You speak about the documentation but I think that an example allows to understand a documentation well. Sandra -Original Message- From: Taylor, Jason [mailto:[EMAIL PROTECTED]] Sent: 25 September 2002 16:31 To: 'Struts Users Mailing List' Subject: RE: Struts tags for display a collection of views I think you're talking about paging through a dataset a certain number of records at a time. If I'm right then we're talking about some sort of collection with a class or set of classes whose mission in life is to provide meta-data about the collection like Page 5 of 6, current selection is Record #34, etc. It's a pattern, though I'm not sure what you'd call it other than paging, though unfortunately paging makes people think of little electronic devices that annoy people automatically, so there should be a better word for it. Bottom line-- what you're talking about is something you could handle on the front end (in Javascript or some other scripting language) or the back end (in your Java classes that make up and service your Model), depending on your preferences/strengths. What Struts provides you is the framework for passing the data between the front and back end that shields you as much as possible from the details of how the servlet container works. Sometimes you'll get rather curt answers if it sounds like you're expecting Struts to provide features that are more high-level than that of a webapp framework.

RE: initilaizing form bean values
I would use your setter methods to initialize the bean in the reset method rather then
removing it from scope.
We have several forms which we pre-populate from a single-sign-on database so that the
user does not have to type in their name, address etc. We have one action that
displays the form and another that processes it (sometimes they are the same action
class, with different parameters.) When the Action to display the form is called we
use the setter methods in the form bean's reset() to get data from the DB and then
display it.

If a user cliks the edit button i go back to the action class.

i have this code in the action as usual
if (mapping.getAttribute() != null) {

request.removeAttribute(mapping.getAttribute());

session.removeAttribute(mapping.getAttribute());

this removes the previous form bean instance. SHOULD I REMOVE THIS CODE and

RE: Need Help Fast
Essentially, he is saying you can rewrite your doStartTag method to be something like:
private List _states = null;
public int doStartTag() throws JspException {
if (_states == null) {
_states = new java.util.ArrayList();
_states.add(new com.ubspw.cdd.common.LabelValueBean(-Select One-, ));
_states.add(new com.ubspw.cdd.common.LabelValueBean(AK,AK));
_states.add(new com.ubspw.cdd.common.LabelValueBean(AL,AL));
_states.add(new com.ubspw.cdd.common.LabelValueBean(AR,AR));
...
...
}
pageContext.setAttribute(selectStates, _states);
return (EVAL_BODY_INCLUDE);
}
this way, states will only be set up the first time doStartTag is called.

Hello,
One possible solution:
Put the ArrayList in application context and put a check in doStartTag()'s
beginning to determine whether the list of states can be found in
application context.
Instead of:
pageContext.setAttribute(selectStates, states);
Put it like this:
pageContext.setAttribute(selectStates, states,
PageContext.APPLICATION_SCOPE);
And in the beginning of doStartTag():
Object o = pageContext.getAttribute(selectStates,
PageContext.APPLICATION_SCOPE);
if (o == null) { ...do what your current code does...
}
else { ...do nothing... }
But why do this in a tag at all? If your list of states never changes, you
might as well initialize it in an init() method somewhere.

Ive done this, everyone is overcomplicating it greatly...
Lookup.getData() gets an ArrayList of states.
This array list is loaded through an XML file that loads upon boot and puts
it in a static variable. This XML file can load it from itself or from the
database. It does all the .add() .add() .add() etc. This should NOT be done
in a jsp tag. Done once and pulled from static method like below. Nice and
simple.
Here's the JSP code.

Lookup.getData(Constant.GLOBAL.UNITED_STATES)); %

DTD
I'm new to this list, so forgive me if this question has been posted recently. Yesterday my Struts application stopped working. I finally traced the problem to the following line in struts-config.xml: !DOCTYPE struts-config PUBLIC -//Apache Software Foundation//DTD Struts Configuration 1.1//EN http://jakarta.apache.org/struts/dtds/struts-config_1_0.dtd; Apparantly the Apache domain was unavailable for awhile on the web and this caused the parser to hang. (I was surprised not to see any mention of this anywhere. I would have thought that Struts apps all around the world would have stopped working.) To fix the problem I placed a copy of struts-config_1_0.dtd in the same directory as struts-config.xml and changed the reference to: !DOCTYPE struts-config SYSTEM struts-config_1_0.dtd When I start the application, I get a parser error stating that it can't find the resource in the directory that the VM (i.e. Weblogic) was started from. According to the XML spec, the SYSTEM specifier should tell the parser to look for the resource in a path relative to struts-config.xml, in this case - the same directory. Anyone have any insight into this?

Re: Unit testing a struts application
Also for unit testing actions out-of-container, take a look at StrutsTestCase : http://strutstestcase.sourceforge.net/. One approach that is also commendable for unit testing - regardless of servlet framework used - is to keep as much code as possible out of container-dependent objects. For instance, if you can have a Struts Action class delegate work to a regular java object with non-container parameters passed, rather than doing that work in the action itself, than the code that does the work can be more easily tested with vanilla Junit. For in-container testing, which we have used a lot for acceptance tests as opposed to unit tests, Cactus as recommended by Jim comes up a lot. We use HttpUnit: http://httpunit.sourceforge.net/. We also ended up wrapping HttpUnit with a somewhat simpler API that is on sourceforge as well: http://jwebunit.sourceforge.net/.

RE: Distinct case in validate() with a form used in several page
I use the DynaValidatorActionForm and identify the validation routines in the validation.xml by the action mapping and it works quite nicely. Is this an acceptible way? It works well for me.

RE: ActionForm
I just ran into a similar problem where I have a set up action which populates the form (in request scope) and forwards to the .jsp page. When validation failed, I had my input attribute set to the .jsp page and was getting the behavior your described. I changed the input attribute to be the action mapping of the set up action and the problem went away. If you think about it, it makes sense. The set up action stores the list/options data in the request scope. Once the page is render, then its gone. If you try to access the page directly without going through the set up action, then the form never gets populated with the data. By setting the input attribute to the set up action action mapping, the data is retrieved and populated and therefore can be rendered to the screen. robert -Original Message- From: Desjardins, Nicolas [mailto:[EMAIL PROTECTED]] Sent: Thursday, September 26, 2002 10:42 AM To: 'Struts Users Mailing List' Subject: ActionForm Hi, i have a Form (ActionForm) in wich i have a list that is feeded from my database.

Problem viewing web from outside company -- UnknownHostException
Hello all. I have a struts-driven web working under Tomcat 4.0.4, Struts 1.0. All is well from within my company on any given machine but when I access the web from outside the company I get an java.net.UnknownHostException error.

RE: Unit testing a struts application
I totally agree with this approach. Here is how I abstract Struts away from http: http://www.mail-archive.com/struts-user@jakarta.apache.org/msg40143.html This way, I can test as close to the protocol as possible, allowing me to remove the protocol-specific issues. Then if a bug comes up, I can determine if its in the JSP/field bindings/HTML, the action logic, or the business tier using my various tests to quickly narrow down the issue. You can then supplement with in-container testing as desired.

[OT][WORKFLOW] Any best practice for back, save, continue buttons?
I'm thinking about a design where I maintain a URL stack in a session variable that stores where a user has been, so that clicking a back button (not the browser's) will take a user to the right place. It would work like this: Click a Continue button - Push a new URL onto the stack, and take the user to that page Click a Save button - Leave the stack alone, and return the user to the same page Click a Back button - Pop a URL from the stack and take the user to the URL on the top of the stack. Click a Done button - Clear the stack. This would happen when you click a link on a top nav bar or the finish button in a wizard, for example. These would be the basic types of navigation. The actual labels on the buttons or links could be whatever you want. For example, you could have a Continue button labeled Save that takes the user to another page.

RE: [OT][WORKFLOW] Any best practice for back, save, continue buttons?
Im using something a little more complex that is a bit similar. I store some information into a uniquely identified object in the session , this includes the ActionForm the user is currently editing a url to resume editing this, then I forward to another page where the user can edit something else (perhaps a detail record). The user can repeat this process to stack to any number of levels. When an operation is complete the user is returned to the form they were previously editing (the actionForm having been preserved in the session) to continue editing it in the state is was before they diverted.

RE: [OT][WORKFLOW] Any best practice for back, save, continue buttons?
Dan, I did something in the past related to this, before Struts was available (I think). It required new instances of an action to be created for each jump with return, which cluttered the session but enabled these actions to store state about the process. Anyway, the one thing I learned, no matter what approach I take, is that the state of where the user is - be it the page, step, next step, where you came from, etc. should be in the form as a hidden field (i.e. dealt with in request scope) whenever possible. This allows the server to always stay in sync with the user, no matter if they use the back button or open a new browser window and start a new wizard, since the previous form has its wizard state, such as its current page, in the HTML and not on the server side where it can get out of sync. Stacks on the server side are painful and never work, but lists with an index to the current location in the wizard that are always sent to the action in the request (via a hidden variable in the form) work best.

RE: [OT][WORKFLOW] Any best practice for back, save, continue buttons?
Im using something a little more complex that is a bit similar. I store some information into a uniquely identified object in the session , this includes the ActionForm the user is currently editing a url to resume editing this, then I forward to another page where the user can edit something else (perhaps a detail record). The user can repeat this process to stack to any number of levels. When an operation is complete the user is returned to the form they were previously editing (the actionForm having been preserved in the session) to continue editing it in the state is was before they diverted. (Incidentally, using the browsers back button in such a case results in a rather bad case of server state confusion!) -Original Message- From: Jacob Hookom [mailto:[EMAIL PROTECTED]] Sent: Tuesday, September 24, 2002 14:56 To: 'Struts Users Mailing List' Subject: RE: [OT][WORKFLOW] Any best practice for back, save, continue buttons?

RE: [OT][WORKFLOW] Any best practice for back, save, continue buttons?
Dan, I did something in the past related to this, before Struts was available (I think). It required new instances of an action to be created for each jump with return, which cluttered the session but enabled these actions to store state about the process. Anyway, the one thing I learned, no matter what approach I take, is that the state of where the user is - be it the page, step, next step, where you came from, etc. should be in the form as a hidden field (i.e. dealt with in request scope) whenever possible. This allows the server to always stay in sync with the user, no matter if they use the back button or open a new browser window and start a new wizard, since the previous form has its wizard state, such as its current page, in the HTML and not on the server side where it can get out of sync. Stacks on the server side are painful and never work, but lists with an index to the current location in the wizard that are always sent to the action in the request (via a hidden variable in the form) work best.

using tiles and j_security_check
Hello, I am using tomcat's realm authentication to protect my struts 1.1 app. The actual form is constructed using tiles. This works fine for the most part but occasionaly I will submit the login form and get stuck at a blank page with a url of http:/mysite/j_security_check Usually I have to retry it a few times and then it will work. Has anyone seen this behavior? Should I feed tiles a plain html and not use tiles for that? I am also looking to see if this could be some kind of session problem.

We use resin and according to http://www.caucho.com/resin/ref/app-config.xtp#session-config you can indepently turn off either cookie sessions or url-sessions.

I'm not sure I understand.. if I use in my JSP the standard form tag I dont get this jsessionid parameter when browsing to the page. Is there a way to use struts' html:form tag and not get this jsessionid? If you use FORM based auth and disable cookies and don't use the EncodeURL() you have to reauthenticate yourself for every request. I can see the jsessionid appended only on the first page after the login page if I have cookies enabled. I suspect that the jsessionid is added to the url by calling EncodeURL() at the struts taglib. I know that this may introduce problems to cookie-disabled visitors, but I don't want the jsessionid to appear. Create a filter which processes the output and cut off from jsessionid to the first ; in each page for each occurence of jsessionid. If you insist. Why does it bother you? Tib
RE: DTD
Hi Jeff: It appears you have a mismatch of identifier (1.1) with DTD (1.0) in your !DOCTYPE tag. Change your identifier to 1.0 to be consistent with the DTD URL and then your app should work whether the struts site is up or not. (Assuming your app is a Struts 1.0 app) The ActionServlet will use the DTD in the struts.jar if it recognizes the identifier. That's what we've been doing with Struts 1.1 successfully on a server with no web access.

I believe what you're trying to do is covered by the contextRelative attribute of the forward. Have you tried setting 'contextRelative=true' on a forward? What it does is tell Struts Interpret this as though it's relative to the APPLICATION context (not module context).

RE: Logout in a container-managed security environment -- Follow-up
All: I made the original post in this thread, and thanks to the replies I received, was able to implement FORM-based CMA in my application. As you can see in the message below, I was left with one residual problem: Although FORM-based CMA worked fine in a standalone Tomcat environment, when I switched to an integrated Apache-Tomcat environment, I got a 404 not-found error from Apache for j_security_check; in other words, Apache never passed this request through to Tomcat. Again thanks to several replies I received, I've been able to resolve this problem. Eddie Bush, in particular, was helpful and asked me to post the solution on this list when I found it. So here goes. Bear in mind that, in the example below, ebps is the name of my application domain. The solution involved modifying Tomcat's mod_jk.conf file. The original set of mappings in mod_jk.conf for my application context was: JkMount /ebps/servlet/* ajp13 JkMount /ebps/*.jsp ajp13 JkMount /ebps/ ajp13 JkMount /ebps/*.do ajp13 On spec, I tried adding various mappings that assigned j_security_check to the ajp13 worker. The mapping that worked is: JkMount /ebps/* ajp13 .which in effect maps ALL requests to the ajp13 worker.

One of the replies recommended an article on the topic, which I downloaded and read. I implemented FORM-based authentication, making the changes to my web.xml, indicating the login form and error page, etc. The container (Tomcat 4.0) seems to know that I want FORM-based authentication, since it pops up my login page. I did, by the way, include the fields j_username and j_password, and my form action is j_security_check, as per the instructions. However, when I press the submit button, my browser gives me a 404 not-found error on the (nonexistent, of course) page j_security_check. I've checked the Apache and Tomcat logs, and one of the Tomcat logs tells me that it has Configured an authenticator for method FORM, but it still seems to be looking for a page by that name rather than invoking the method.

cancel and session-scope form
Hi there, How can I prevent a cancel button from populating the form bean? Normally this isn't a problem, except that my form bean is in session-scope (for an wizard-like implementation). I've considered reconfiguring it so that the form stays in request-scope for each page in the wizard. I would then instantiate the form in session-scope myself and manage the copying of form fields from each page manually depending on if the user submitted or cancelled. But I was hoping for a simpler solution. thanks, Angie -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
Re: multiple sub projects
That's a very good question. Personally, I see added overhead (necessity for multiple instances of certain things to be loaded) in the current implementation. The positive side is that I can configure each module with it's own look and feel - and tell which one I am in. You're right though, the biggest thing is that you can multi-task the development better because of having a configuration file for each module. That was the primary goal, I believe. They did a good job of accomplishing that. I *really like* the sub-app idea, but I think that it needs to be taken further. Having the default sub-app act as a global sub-app (which the others could share the config of) would, I believe, be ideal. Yes, you can get away from duplicate effort by having your build concatenate property files and the like, but, unless I miss my guess, you're necessitating the instantiation of unnecessary objects --- one of which could be a pretty big thing: data-source. I don't personally use the Struts-configured data-source, so it's not an issue to me, but, by partitioning into sub-apps you would have to define a data-source for each module that needed data access. Unfortunately, as I see it, doing this blows all kinds of holes in pool management strategies. How do you possibly configure the pool so that you're not asking for connections you don't have enough licenses to cover, for example? If for only pieces of the configuration, I believe the next logical step is to evolve the default sub-app into a global sub-app, which would get checked for config objects, absent those same objects in the current module. Yes, I'm talking about module inheritence. I wouldn't think it would be that difficult do implement -- the current module's config is placed in request scope, and the default sub-app's config is placed in application scope. You'd just have to refactor things to check one - then the other - before deciding things didn't exist.

RE: multiple sub projects
My interest in multiple sub-apps is more related to maintenence and post-launch life cycle issues. Modular development is nice, but to me fine-grained control of override behavior for every aspect of the deployed application is crucial-- that way I can add functionality or upgrade any feature of an application without touching any of the original version's code/media/configuration, while keeping it all in one deployment unit. This makes it possible to more organically migrate (or rollback) from one version to another. It also reduces the amount of duplicated code/JSPs/media/etc drastically when closely similar versions can share things. -Original Message- From: Joe Barefoot [mailto:[EMAIL PROTECTED]] Sent: Thursday, September 26, 2002 10:20 AM To: Struts Users Mailing List Subject: RE: multiple sub projects Pardon me if this questions seems a bit daft, but what does using multiple sub-applications buy you other than splitting the app. into logical chunks, each with its own config file? -Original Message- From: Eddie Bush [mailto:[EMAIL PROTECTED]] Sent: Thursday, September 26, 2002 10:23 AM To: Struts Users Mailing List Subject: Re: multiple sub projects I believe what you're trying to do is covered by the contextRelative attribute of the forward. Have you tried setting 'contextRelative=true' on a forward? What it does is tell Struts Interpret this as though it's relative to the APPLICATION context (not module context). I know this works for global forwards, and I believe it would also work for a local one. Note that by specifying contextRelative=true you must provide a path which is, in fact, relative to the application and not the module :-) Anthony Martin wrote: What about situations where a common .jsp file is used as a target for forward by multiple sub-applications? -- Eddie Bush -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED] -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
bean:write formatKey doesn't work with Strings?
I have been looking into the formatKey option of the bean:write tag. I have format.creditlimit=$###,###,##0.00 in my property file. My jsp has the following: bean:write name=responseBean property=creditLimit formatKey=format.creditlimit/ I am trying to work only with strings between by controller and view, so I originally had the getCreditLimit() method return a String. This did not work, the string was not formatted in the resulting html. ex. 006500 However, when I changed getCreditLimit to return an int, then the formatting was applied. ex. $6,500 I understand why bean:write formatter would expect a number. Is there a way to still use Strings in your getters and setters of your form beans when you want to use the format features of bean:write?

RE: multiple sub projects
Thanks for the evaluation. I'm going to have to politely disagree with your assessment that you can multi-task the development better because of having a configuration file for each module. Unless you're in an environment without source control, I don't buy the argument that maintaining multiple config files is easier than just one. We were doing exactly this at my last gig, by using an Ant task to push our multiple config files into a single struts-config.xml, and, quite frankly, it was just a pain in the ass. I'd rather just use logical divisions within a single config file to group actions that belong together. That way I only have to have one config file open if I'm making spot changes in different parts of the application, and I also don't have to worry about which sub-app I'm in or transfering to a different sub-app, regarding the URLs in my JSPs. Judging from the traffic on the list, using multiple sub-apps. creates more confusion than it does clarity, which is what I believe was its original intent. Of course, if it works for you and your team, that's all that matters. :) peace, Joe -Original Message- From: Eddie Bush [mailto:[EMAIL PROTECTED]] Sent: Thursday, September 26, 2002 10:48 AM To: Struts Users Mailing List Subject: Re: multiple sub projects That's a very good question.

Please help with iteration problem
I am trying to nest iterate tags. I've tried logic:iterate nested:iterate and c:forEach without success. Here's what I want to do. logic:iterate name=routes id=route type=RouteBean write stuff about the route. logic:iterate name=route property=segments id=segment type=SegmentBean write stuff about the segment /logic:iterate /logic:iterate routes points to a java.util.List of RouteBeans. Each RouteBean has a method, getSegments() that returns a java.util.List of SegmentBeans. I've looked at the documents and examples for the nested tag, but I don't see anything about this type of nesting. I don't have a monkey with a single bunch of bananas, instead I simply have a java.util.List of bunches, each of which has a java.util.List of bananas. I'd really appreciate any help ya'll can give me. I'm up for using any tag type (struts-logic, struts-nested, or JSTL). I'd just rather not fall back on scriptlets if I can help it.

Storing a bean in my FormBean
My FormBean
has a property that is a custom type
(com.mycompany.myclass).
I have added
this property to my form definition in struts-config.
My
ActionClass does a
request.setAttribute("beanname",instanceOfmyclass);.
Back on my
jsp, it is really easy to bean:write from my
instanceOfclass.
The question
is, how can I then put instanceOfmyclass back into my FormBean as a property so
subsequent calls to the ActionClass can access it?
Thanks
alot,
Glen
