RE: Form's property, String or not?
For actionforms you should make them all strings. Certainly anything that allows for text entry in the UI should be made a string even if it is intended for numeric input. (For checkboxes and such like its less important though Id still recommend using strings for them) This allows you to return the user to the form when validation fails with the input they entered preserved - so if they type One instead of 1 the bad value will be preserved for them to correct on return to the page. If they type text into a field whose actionform property is numeric you can have problems handling it. I cant remember if it causes an exception or is just converted implicitly to the value 0 - but either way its a problem... -Original Message- From: Xuemin Guan [mailto:[EMAIL PROTECTED] Sent: Wednesday, 24 March 2004 11:30 To: Struts Users Mailing List Subject: Form's property, String or not?

RE: help in java script
Remember the JSP script is evaluated server side and its result is what is
rendered to the browser.
Only the resulting html is what is evaluated by the browser which knows
nothing of the original scriptlets.
To check this out just do 'view source' in your browser on the page so you
can see what is actually being rendered to the response and seen by the
browser!
% String value=hello;%
html:text size=20 property=userId
onchange=javascript:find(%=value%)//TD
Will cause (something like) this to be rendered:
input type=text size=20 name=userId
onchange=javascript:find(hello)/
BTW: Should have spotted earlier the javascript: which also is not
wanted - you only use that for hrefs! Take that out you get:
input type=text size=20 name=userId onchange=find(hello)/
As you can see you are trying to pass a javascript variable named hello to
your method.
Surely you want to pass a javascript string containing the text hello?
ie:
input type=text size=20 name=userId onchange=find('hello')/
Hence my suggestion to add in the quotes.
And lose that javascript: prefix!
(And shove a semicolon on the end though I think its optional in this case!)

Hi Andrew and Shobhana,
As far as I know, you cant mix static text and dynamic text within a JSP. If
I remember correctly, something like the following code should work.
%
String tempString=javascript:find( + value + \;; // Not sure about
the semicolon...
%
and then:
html:text size=20 property=userId
onchange=%= tempString %//TD
I'll make sure to try the single quotes (') around the dynamic text some
time, cause it's really annoying to use the method im describing here.

RE: Help on struts
I guess the first thing to consider is what you mean by come back to the previous page. Do you just mean have the user redirected back to that url when they have finished playing with the search? or is it more complex. For example the previous page is a form, and they are halfway through filling it in when they need to search, and on completion need to take up where they left off with filling it in? In the first case the easiest way (Im assuming there are multiple places that send you to the search page) might be to have the link to the search page add a parameter to the url containing the name of an ActionForward that will take the user back to this page. The search page can make note of this forward name, and when the user is finished searching can look it up and return it as the forward from the searchs action. -Original Message- From: Shoaib [mailto:[EMAIL PROTECTED] Sent: Saturday, 13 March 2004 14:01 To: 'Struts Users Mailing List' Subject: Help on struts We are using struts 1.1.

RE: can anyone help me address this issue
I sometimes have to do things like this. You can only submit strings in the
request, so what you want is a method of representing your information as a
string in a simple way.
In this case it should be quite easy as its just an array of a simple
structure of two ints so Id probably just have two delimiters, one for the
values in the structure, and one for the structures, so for example I might
submit the lot in a hidden field as something like:
1,32;2,48;3,10;4,50
Where I use a comma to delimit between the colIndex and newWidth values, and
a semicolon to seperate each instance of the structure. You can use any old
char as a delimiter so long as it wont be confused with the values. Since
these are ints and not strings life is easy in this case!
Over on the server side you have some code that parses this string to
reconstitute the values into some kind of java classes. You may even want to
do it in your action forms setter or getter - where you pass the string when
it is set and have a (differently named) getter that can return it as the
equivelent Structure[]

You can't send data structures over HTTP you can only send strings.
You could set those values as hidden form elements with a naming
convention that would enable your server side code to recognize
the elements in the request and create the appropriate server side
data structure. This is essentially what Chris has suggested.

use onResize on the html element that is clicked to report its new value

you need to hide the submission of the form use an IFrame.

I've come to the conclusion that I'm disappointed with JSF. Yes, I see what
it's trying to accomplish, but it puts too much overhead in the JSP
designer, you can't easily create dependencies in the controller, no
exception handling, etc.
http://forum.java.sun.com/thread.jsp?forum=427thread=490234
Based on what I've learned from JSF, I'm working on a framework called
Banten which is an attempt to remove the need for Actions/Forms, etc (yes,
I've jumped on the bandwagon).
So then your actions can be chained on a single request as:
#{orderController.order.addLineItem(param.id}
#{orderController.order:validate()}
I've finished the expression parser (it actually benchmarks a good deal
faster than the current EL implementations). Now to finish the Controller

Yeah, package is org.apache.banten.*
I just ran some benchmarks for bean properties and method invocation through
EL, and my version of the EL parser is running about 5 times faster, for
bean property invocation. For straight method invocation (a replacement of
the MethodUtils in Commons Bean Utils) it executes about 10-20 times faster

Subject: RE: JSF RI Final is out!
I've come to the conclusion that I'm disappointed with JSF. Yes, I see what
it's trying to accomplish, but it puts too much overhead in the JSP
designer, you can't easily create dependencies in the controller, no
exception handling, etc.
http://forum.java.sun.com/thread.jsp?forum=427thread=490234
Based on what I've learned from JSF, I'm working on a framework called
Banten which is an attempt to remove the need for Actions/Forms, etc (yes,
I've jumped on the bandwagon).
So then your actions can be chained on a single request as:
#{orderController.order.addLineItem(param.id}
#{orderController.order:validate()}
I've finished the expression parser (it actually benchmarks a good deal
faster than the current EL implementations). Now to finish the Controller
:-)

RE: Viewing .pdf files usign struts frames work..
Since you are writing the response from your action you should return null
from execute() to indicate to struts that the response has been handled and
that it should not forward.

RE: Question
If you want to get better answers quicker Id suggest you learn the concept of 'meaningful subjects' for emails. Question is not a meaningful subject line. http://www.catb.org/~esr/faqs/smart-questions.html Ok now on to your Question. Having been kind enough to take the time to read it to see if its something I can help with I have found you are in luck. So here is an answer: For 'complex' stuff like this you could make full use nested beans as demonstrated in this tutorial: http://www.keyboardmonkey.com/next/index.jsp In this case as its just one column of text fields you could also get away with just using a collection property in your actionform, and you could back it with a lazy list from commons collections: http://jakarta.apache.org/commons/collections/api/index.html Your view rendering code could iterate through the collection rendering out fields for each: ie renders the html: input name=condition[3] value=foo/ (I think the nested tags can do the indexing for you if your using JSP? not sure. Dont use jsp myself) Your 'add' button or 'conditions link' or whatever would submit and on the server side you try to get the next three items from the lazylist causing them to be instatntiated by the factory you specify. On return to the view the extra fields are rendered ready for input. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Thursday, 4 March 2004 06:03 To: [EMAIL PROTECTED] Subject: Question Hello All, I have a requirement, where on page we have 3 fields named condition1, condition2, and condition3.

Using commons-collections lazylist for nested actionforms

Basically, i use velocity only for email templates and sometimes to generate
other kind of templates from one template where the use of XSLT is not
appropriate.
For web templates, that have more complex requirements, i prefer to use
taglibs. besides el makes life as easy as we may talk in velocity. In

I am starting to develop an application using struts and have been
looking round the rest of the Jakarta project and came across the
Velocity project.
I was interested to see which which people recommended for a relative
newbie
After looking at velocity, I am certainly of the opinion that it adds no
value over
jsp2/jstl. It offers absolutely nothing that the jsp2/jstl combination
does not.
The only difference is that velocity is a bit more terse (if/else/end
instead of
c:choose/c:when/c:otherwise) and that it uses # instead of the .
It is important to note that I am talking about jsp2 and tomcat 5, not
the jsp1 in
tomcat 4.
A while back I looked in detail at the jsp/velocity comparison on the
velocity site.
There are several issues with the comparison. The person writing the
case study
was cleary biased towards velocity and had never even considered JSTL
(which
in all fairness may not have been available at that time). Looking at
the code
(both the velocity and jstl versions are below) I think that velocity
clearly had
an influence on the jsp2/jstl constructs.
The first thing I noticed was that the two pages do not do the same
thing.
The jsp turns off the session (the vm does not). The jsp stores
variables that
are never used which were factored out in the vm version. The vm version
is missing required code (for example, the repCode and urlEvent
variables
are never defined).
The jsp page is also *very* poorly written using scriptlets. You should
rarely need
to use scriptlets in jsp1/jstl pages, and I suspect with jsp2/jstl, you
will not ever
*need* to.
With struts, you do not need to use jsp:useBean tags either because
the controller
does that for you.
The jsp2/jstl version is a bit more verbose because it is based on xml
so you
cannot have things like if/else/end because they are unbalanced, but
other than
that, there are no significant differences.
After converting the page to use JSTL and eliminating ALL of the % %
stuff, we
get something more like this:

RE: Problem with loss form (session scope)
Ah! So the form is there! Just not the values? hehe , ok I better explain about reset(). The reset() method is always called (by the request processor) before it populates the form from the request. (As you noticed this occurs regardless of validation results). The reason for this is due to the (primary) purpose of the reset() method, which is not so much to reset the form to default values, but rather to act as a workaround for the issue that browsers do not submit values for certain types of fields when they are empty - for example multiple select fields, and unticked checkboxes. With a request scoped form you get a fresh form everytime anyway so this issue isnt often an issue, but with a session scoped form it can be. Now if a user were to untick a checkbox on a form or deselect all items in a multiple select box, or clear out all the text from a textarea, _nothing_ (not even an empty string) is submitted in the request for that field. (Remember at its heart the submitted request is just a bunch of name=value lines, and this is converted to a map by the servlet api, struts (or rather beanutils) iterates the parameter names in said map and calls the appropriate setters in the actionform with the value) As a result the setter is not going to be invoked as there is _no_ parameter in the request for that field. Thus the value in the actionform will not be cleared, and the unticking of the checkbox will not be seen on the server side. By clearing the value for the field in reset() before populate is called the value is cleared. If the value submitted was not empty, then the setter will be called and the correct value replaced, if not then the cleared value remains in the form as the setter is not called so either way the form reflects what the user entered in the UI. This is all well and good if all the fields are present in the UI, but if not - such as in the case of a multiple page wizard - then we are going to be clearing values in the actionform that should not be cleared. The answer to this is to keep track of which page the user was submitting from and only clear values in reset() for fields that are on that page - leaving the others untouched. (You can submit the page id in a hidden field and check its value with request.getParameter() if needs be). hth Andrew -Original Message- From: Betty Koon [mailto:[EMAIL PROTECTED] Sent: Saturday, 28 February 2004 06:03 To: 'Struts Users Mailing List'; [EMAIL PROTECTED] Subject: RE: Problem with loss form (session scope) One thing I found out that the reset method was getting called everytime if there is no error return from validation.

RE: [OT] JSP or Velocity
Havent used velocity myself , but from what Ive seen it is very good. (Theres also a very good introduction for newbies in Teds Struts in Action book where hes given a chapter to using velocity with Struts) That said, if you learn JSP its probably a much more portable skillset that will stand you in good stead for future projects and jobs, and theres a lot of freely available taglibs out there you can utilise. Much more support on the list too for any problems you may come across, and of course theres the Tiles stuff which (again Ive not used!) is really very very cool and powerful! My own personal opinion of JSP otoh is rather low. I just dont like the whole 'vibe' of it! Suffice it to say Im not a big fan of serial rendering mechanisms - especially where the page layout and rendering instructions are combined in the same file - and also much prefer a mechanism where I can render to any part of the view at any part of my rendering process (Im using a homebrew library for this that revolves around using a tree of decorator classes to modify xhtml DOM templates - there are some open source libraries for DOM based rendering available too such as XMLC which you might want to look at if you have time). Of course that power comes at a cost in terms of performance and memory usage, but for the type of apps Im working on its not really an issue. But weighing up the arguments for your case, Id say the best advice I can give is that nobody got sacked for choosing JSP and its the one with the most mindshare despite its flaws, so you wont go wrong going with it for your project even if it can be a pain to work with sometimes! -Original Message- From: A.White [mailto:[EMAIL PROTECTED] Sent: Friday, 27 February 2004 20:45 To: [EMAIL PROTECTED] Subject: [OT] JSP or Velocity Howdy I am starting to develop an application using struts and have been looking round the rest of the Jakarta project and came across the Velocity project.

RE: [OT] JSP or Velocity
Yes, Velocity has been around for quite awhile now, and it was intended to
address many of the problems inherent in (older versions of) JSP.
Nowdays JSP (especially JSP2) coding techniques and technologies have rather
caught up with velocity. Your assesment that it doesnt add much value over
the EL capabilities in JSP2 is pretty much on the mark. Of course it wasnt
always this way and for a long time velocity was much nicer. (Still looks
nicer ;-)
I reckon you are also correct in believing that velocity design provided a
lot of the inspiration for the jstl stuff.

if that does what you want start debuging the functions by using alert

if you use double quotes like you seem to be you may have to escape

Forms have no business transfering stuff from view to model. The model should never have to see an actionForm and should be blissfuly unaware of their very existence. Thats the job of an action to do, taking data from the form, and providing it to the model and vice versa (preferably with some kind of helper classes and perhaps also non-form DTOs involved) -Original Message- From: Niall Pemberton [mailto:[EMAIL PROTECTED] Sent: Friday, 27 February 2004 12:12 To: Struts Users Mailing List Subject: Re: FormBeans: A question of Style Dam - I was in Camp 3: Form beans are View components...but looking in the user guide...

They should both collect submitted data and provide the JSP (or other view components) with most or all the data they need to render the page (camp 2). I say 'most' only because sometimes custom tags can be useful for getting data for list boxes, etc. All the data that the Action collects, however, should be carried to the JSP in the ActionForm. The alternatives for carrying data from Actions to JSPs for the camp 1 gang are not attractive, in my opinion. Having an Action put a bunch of stuff into the request or session scope creates a lot of coupling between the Action and JSP. The Action must know where to put it and the JSP must know where to find it with that scenario. I prefer to keep the Actions and JSPs loosely coupled by having them both depend on the ActionForm, rather than depending on each other. The Action populates the ActionForm, and the JSP renders it. For complex pages, the ActionForm can be the root of an object graph that contains all the data you need to render the page. Stashing additional info all over the session and request is sloppy by comparison, in my opinion. I think the ActionForm is the root of all view data approach promotes more concentrated thought about the structure of the data, which is a good thing. It provides a more concrete interface between the controller (Action) and view (JSP) components. Maintaining JSPs that get their data from one place is much easier than maintaining JSPs that have to collect, organize, and display data from multiple sources. JSPs that pull data from the ActionForm, stuff stashed in the session, and/or stuff stashed in the request are harder to maintain. Where do I find it? How does it all relate?

RE: Problem with loss form (session scope)
Ah, but you didnt actually answer my question. Is it the same name for the form in both actions mappings, and do both these action mappings specify the scope to be session? My suspicion is that the problem is that struts is trying to find the form under a different key in the second action - but is this second action actually the same action as the first or different as I am assuming? btw: have you gone and looked at the struts source code for the request processor and request utils class to see what it is actually doing?

One of the common attitudes in open source is that the source is the best reference and I certainly found this the case when I was first learning struts :-) -Original Message- From: Betty Koon [mailto:[EMAIL PROTECTED] Sent: Friday, 27 February 2004 15:10 To: 'Struts Users Mailing List'; [EMAIL PROTECTED] Subject: RE: Problem with loss form (session scope) I specify my own name in the struts config.

RE: ActionForms Thread Safe
snip If this is case then ActionForm are not thread-safe. Because Two request from different client can simultaneous come in and use the same ActionForm instance? I know this is not the case, but I cannot figure out how is it thread safe? /snip Actually it is the case! - but only in certain cases when you have a session scoped actionform. Under these conditions it is possible for more than one thread to be playing with that actionform at the same time. Where this could occur is when the user has multiple windows open (or does a very rapid double submit) and fires requests in both windows that map to the same action mapping. You will note that it only affects that particular session. Other sessions running at the same time will have their own actionforms of course, and different actionmappings can use different attribute keys to store the form under. So you only have a problem where you need to support multiple windows/frames (and thus potentially threads) for the same actionmapping for the same http session and you use session scoped forms.

RE: [OT] - Request against Session
snip My recommendation is to *always* use request scope form beans if you can. /snip Yes. Having done it both ways and experiencing the various tortures that session scoping inflicts apon us I would definately agree that if one can use the request scope (and with a little thought this should be possible in most situations) then do so. It eliminates so many hassles. That said, I do have a small minority of forms in one of the apps I did that could be in request but arent - the reason being most of the forms need session scope (see below) and they all share a ton of common code in the actions and renderers superclasses - and being able to make the same assumptions and reuse the same code makes life simpler rather than making special exceptions for those forms. snip The only reason a form bean should ever be in session scope is if you want it to preserve values across requests that are not included in the form on the current page. /snip There are two things I am doing with session scope that would be quite hard to do with request scope and they meet this criteria. (Well three if you include tab-panes, but if one drops support for netscrap6 then they can be done with css hiding now) The first is supporting multi-file fields. (Fields that allow uploading of n files). In this case we need somewhere to put those files or at least info about them (ie: session) until such time as the user has both finished adding files to the file fields on the form, and has also passed form validation. At which point we can finally process these files (for our apps this usually involves just persisting them somewhere.) It is imho (and more importantly in potential customers opinions too) quite unacceptable to force the user to re-upload all fifty billion huge files (a slight exageration) every time they make a typo or forget to fill in some other field on the form. I would think however that this wont play well with clustering (though one could write the files temporarily to a db instead of directly in the session I suppose). (Actually one can code this so that the form is request scoped and one only needs to keep the file manager object thingy in session (and pass its key in the request), but often the form only has a few other fields and its just easier to do it this way) The second thing that I use the session to support is what I call 'diversion'. The app I use this technique in is rather complex. There are several dozen different types of records that can be configured from the UI and most of them have references to other records of other types (foreign keys). Often times one is halfway through configuring one of these records when one realises that one has yet to configure the record it depends on (and the record the record it depends on depends on, etc... ad infinitum). The 'diversion' technique allows the user to divert off to create/edit the associated record without having to either abandon the record they are currently editing (its incomplete so they cant 'save/commit' it as it wont pass validation) or go back to the main window and navigate through the various views to the other records list to popup an edit form for the other record. Instead they simply click a diversion link ( a wee little arrow icon ) next to the select box and are whisked straight off to the edit form for the other record in the current window (either in create or edit mode depending on whether an instance was selected in the select box on the previous screen). They can create or edit the required record (including further diversions for its own dependencies) and once they save it (or cancel) they are returned back to the previous form in the operation stack with all values already input and files uploaded preserved as it was when they diverted. (I actually first came up with this in a vain attempt to try and avoid the need for popups but they were added to the requirements anyway, and in hindsight have made the app a lot more user friendly with both popups and diversions (which are rather like wizards in their ability to guide the user to things that need doing) being supported. Have had a fair bit of positive feedback about it when compared with an earlier swing based version of the app that didnt have this feature - so while its a nuisance to code the payoff is in higher user satisfaction) Since configuring a new installation of the app can involve setting up a lot of records (this aint no 3 form shopping cart) and remembering what needs to be set up in what order and how it all relates can be hard, this diversion mechanism has proved quite popular, and has made it a lot quicker to setup a new installation of the application, or to reconfigure an existing installation. Now I wouldnt recomend this technique for a high traffic public website that gets huge hitcounts, but for an _application_ that is (usually) accessed by intranet by a relatively small number of simultaneous users, and where the complexity of the application is high (and a
RE: Session Validation
Main problem with CMA is that its configuration is container dependent. If your writing an app that needs to be deployed straight to many different containers CMA can be troublesome. btw: if you are doing your own session based security - dont - put check tags in the JSP. Follow Niall's suggestion and hide them under WEB-INF and go through actions to get to them. You can put security checks for the session object in a filter, or if under servlet 2.2 you could override the request processor to do it. If you only need to run on one particular appserver at any moment, then CMA is the way to go unless your requirements are really wierd. Struts ActionMappings support specifying roles required for actions, and (unless you override the RP) this only works with CMA. -Original Message- From: Niall Pemberton [mailto:[EMAIL PROTECTED] Sent: Monday, 16 February 2004 12:06 To: Struts Users Mailing List; hhlow Subject: Re: Session Validation I'm not an expert on security but as I understand you have two choices. You can either implement container managed security - where the servlet container controls logging on and ensures that only authenticated users can have access to the resources you specify OR you can control it yourself within your application. It sounds to me like your asking about the second. Typically when your application controls security, you place something in the User's Session when the user logs on to indicate that they have done so. Then in your Action classes you check the session to see if they have logged on - if not you forward them to the logon screen. If your jsp's are available you also need to protect them - the struts sample used to have a tag (haven't looked at it recently) which did the same kind of check. Alternatively you could hide your jsps in the WEB-INF folder so that the user can't access them directly and you don't need to do the jsp check. The generally accepted view though is that it is better to choose the first option - container managed security. If you use Tomcat, have a look at the web.xml file for the Tomcat admin application (In Tomcat 4.1 its in the \server\webapps\admin\WEB-INF folder). The admin app is actually a Struts application. The security-constraint, login-config and security-role sections are what controls container managed security for that app. Tomcat Admin app web.xml: http://cvs.apache.org/viewcvs.cgi/jakarta-tomcat-catalina/webapps/admin/WEB- INF/web.xml?rev=1.8view=auto Niall - Original Message - From: hhlow [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Monday, February 16, 2004 2:45 AM Subject: Session Validation Hi, I am sorry if this question have been asked before.

RE: [OT] - Request against Session
snip How it is implemented is not important. /snip Well except in that the abstraction cannot be total due to the underlying technology limitations imposed by working with http and browsers over which one has very little control. My example of multiple windows and not knowing when windows are closed illustrates this. Even with a framework in place a developer really needs to be aware of what is going on below his code to support this extra context and sometimes has to add code to supplement this. The session provided by the servlet api has similar difficulties as can be seen with the need for the developer to ensure that they invoke url rewriting on links to cover the case where cookies are disabled. Limiting to one window (and using tokens and other such techniques to ensure that the user sticks to one window) can simplify matters immensely. (The customers desire for multiple windows often rules out this possibility though. Having to suddenly change to support multiple windows when one had been developing all along with a one window restriction can be especially annoying (been there)) -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Friday, 13 February 2004 16:46 To: [EMAIL PROTECTED] Subject: RE: [OT] - Request against Session But what we are talking about is the concept functionality.And what you are saying is the implementation.

RE: [OT] - Request against Session
snip To maintain functionality across a standard scope (request, session, application) something in the work flow application will have to go into that scope or into some other equivalent persistence mechanism such as a database. If the work flow application maintains the persistence, then it is merely using the regular scopes. And, it does not provide any new scope. /snip Yes, the WorkflowScope can never be any more than a way of abstracting some of the tiresome details of managing such session scoped stuff across requests. The code that makes use of the so-called WOrkflowScope can treat it conceptually as a new scope that has many characteristics in common with the session, but underneath it really is just a part of the session or maybe stuff put in a db. That 'stuff' will obviously use storage space (RAM or DB), and knowing when it is ok to discard it is the tricky bit (whether your implementing a workflow framework or doing a one off thing for a particular use case). The worst case scenario is that everything added remains until the session is expired. The best scenario is that everything is removed as soon as it is no longer needed. Depending on the nature of the app, the reality is likely to be somewhere between the two as there are some cases of abandoning a workflow that simply cannot be reliably detected (ie: window closure). -Original Message- From: Michael McGrady [mailto:[EMAIL PROTECTED] Sent: Friday, 13 February 2004 16:57 To: Struts Users Mailing List Subject: RE: [OT] - Request against Session At 12:45 AM 2/13/2004, you wrote: But what we are talking about is the concept functionality.And what you are saying is the implementation.

RE: [OT] - Request against Session
Your not thinking very hard about it obviously. Have a think about this scenario then (which is a common problem I and others have had to deal with before): User is presented with a table of records containing links to edit individual records. Clicking on the link opens the form for that record in a new window (or maybe it doesnt and the user chooses 'open in new window' themself from the context menu). This is because the user often needs to be working on lots of such records at the same time. Now let us assume that the ActionForm for the record editing form needs to go in session scope (nb: in request scope there is not a problem so if the design can be done practically with request scope that is much better). During the course of working with these records the browser is going to be making several trips back to the server to refresh that record. (Maybe it has several select boxes depending on each others value, or it pretends to do tabpanes or is some kind of wizard or whatever). Remember now that the user has several different such records open in different windows. Different record instances but same type of record - and record form - and record action (we are talking about the same ActionMapping here obviously).

RE: what is wrong with this code
snip
Using the solution with the Action shows no parameters
/snip
Attributes and Parameters are *not* the same thing.
Attributes are server side only (and can be any type of object), while
parameters are taken from the request itself and must be Strings.
If you want this value as a parameter this can be achieved by modifying the
request URL you return in the ActionForward.
Since the ActionForward you lookup isnt modifiable (as its a shared
instance) you could create a new ActionForward instance with the appropriate
path and return that from the action. ie:
ActionForward continue = mapping.findForward(Konstanten.CONTINUE);
String continuePath = continue.getPath();
continuePath = addParam(continuePath,
Konstanten.ADRESSEN_RESULT_START_INDEX_KEY, indexListWert);
//assuming indexListWert is a string (you could concat it with one if its
not ie: +indexListWert)
return new ActionForward(continuePath, continue.getRedirect());
and where addParam is just a simple method to return a path with the
parameter appended.
Heres a very simple impl:
protected String addParam(String url, String parameter, String value)
{ //Append parameter and value to url using ? if its the first param or if
its not
return url + ( (url.indexOf(?)==-1) ? ? : ) + parameter + = +
value;
}
-Alternatively you can recode your JSP to look for it in the attributes
instead of the params, though then you will lose the ability to specify it
in the url. (Or you could have it check both)

Not sure how tiles works internally, but I think like most JSP templating
solutions its does a lot of inclusions (similar to forwards). These are
server side so should preserve the request parameters. The included stuff
could modify attributes but I doubt they would modify the ones you set
(unless you included something that you had specifically coded to do so.)
Anyhow I reckon your problem is the attribute vs parameter issue (see my
other reply) so best check that out first.

Betreff: AW: what is wrong with this code
Just to be sure what is in the request my code at the beginning of the jsp
is:
%
java.util.Enumeration e2 = request.getAttributeNames();
while (e.hasMoreElements()) {
String tempString = (String) e2.nextElement();
% %= tempString %=%= request.getAttribute(tempString) %br
% } %
And
%
java.util.Enumeration e = request.getParameterNames();
while (e.hasMoreElements()) {
String tempString = (String) e.nextElement();
% %= tempString %=%= request.getParameter(tempString) %br
% } %
Using this kind of link 'adressenView.do?adrStartIndex=5' shows an
'adrStartIndex=5' at the beginning of the jsp Using the solution with the
Action shows no parameters ... where
Konstanten.ADRESSEN_RESULT_START_INDEX_KEY = adrStartIndex
Putting into the session works perfect :-(

I presume Konstanten.CONTINUE is continue and I see that forward will
default to a non-redirecting forward looking at your config, so thats not
the problem.
Whats in the JSP? You sure you got the attribute key correct there?

Your ImageAction could stream the result in the appropriate format itself. When done, return null instead of an ActionForward to indicate to struts that the Action has already handled writing the response. Not sure what headers etc... need to be set though.

RE: Getting data from a disabled form field
Yep. The browser doesnt submit a value for the field if its disabled. If your using a request scoped actionform then you will either need to reload its value from wherever or add an additional hidden field on the form to submit the value. If its a session scoped form, just make sure that you dont clear it in reset. btw: if this is a security thing then you must make sure that your setters (or something else server side) dont accept different values for these fields when the user hasnt got appropriate rights as a user can easily play silly buggers with the url and script kiddies can easily spoof POST requests - both bypassing any kind of client side validation or 'security'. -Original Message- From: Arne Brutschy [mailto:[EMAIL PROTECTED] Sent: Thursday, 12 February 2004 21:32 To: Struts Users Mailing List Subject: Getting data from a disabled form field Hi, I have a problem with disabled form fields.

RE: Getting data from a disabled form field
They dont submit any parameter in the posted request. As a result, when struts populates the form, iterating the list of request parameters and calling the setters with the values it wont call the setter for that one. The value in the actionform thus depends upon the logic in the forms reset method - and if that field is not reset, upon the pre-existing value in the actionform which will remain unchanged. In the case of a request scoped form, this will of course be a new actionform instance so will give whatever the forms initial value is when the form is created.

RE: [OT] - Request against Session
snip And then he has no more worries as to getting a bloated session, as the session gets trimmed of workflow objects as soon as user goes to any screen which is not part of work flow. /snip Unless of course the user simply closes the window. :-( If the user has multiple windows open all sharing a session and does different things in different windows things get really fun. Im not sure if the livinglogic workflow extension has anything to handle this as I havent used it, but I have some familiarity with some of the issues involved. But in my app I had to essentially manage mini-sessions within sessions (I call them Operation Contexts) and that involved using url rewriting to pass around the id of the OperationContexts so that Actions could identify which OperationContext a request was associated with. (The OperationContexts themselves being essentially an object with Map and some other info. (Or in fact a stack of Maps (to support some other requirements such as nav stacks), but thats starting to get off topic...)) I had overridden the RequestProcessor to allow ActionForms to be scoped to OperationContexts as well which was quite useful. Due to the nature of many of the forms in the app (things like any number of file uploads to a single field and slow access to persistence, and tab paney type stuff that had to work in Netscrap6) we really needed to use session scoped forms, but we also needed to support multiple windows open on html forms for different instances of the same record type (and thus same action and form mapping). Doing this in a frameworky way allows managing this to be abstracted away and so the code in the Actions ( form) can concentrate on the task at hand rather than on session management. As for the session management for this ... what a nightmare (bucket loads of javascript, popups submitting to the server to let it know a window closed, some filters, vast amounts of url rewriting). There are so many edge cases... (and its not actually possible to catch them all) - nasty stuff. If you can find a framework to manage this chaos for you then use it! Its not something you want to do yourself unless you really have to... btw: Ive posted about this Operation Context stuff before a few times so you can search the archive if you want more info. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Thursday, 12 February 2004 21:49 To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: RE: [OT] - Request against Session The whole point is there is no concept of a Workflow scope in Servlet API and if you want to share objects , you have to put them in session.And then clearing them is not always easy, as you will never be clear when user may leave the workflow scope.And you have to code for it in every action.

RE: Struts and Pajes
Hmm. Interesting, saw pajes mentioned on the barracuda list as well. Flavour of the week? ;-) Struts doesnt force you to use JSPs, but it does provide a bunch of JSP tags that make it a very nice fit to use JSP with struts, and of course the majority of strutters are using JSP. The Tiles library is a very big argument in favour of JSPs too. Ok. Enough of the balanced reporting... I have a 'distinct dislike' of JSP, and personally prefer a DOM based approach such as used in XMLC etc... (Im actually using my own home grown method for managing the pages and their DOMs and rendering the dynamic content and doing templating and the like. vanityIts pretty cool/vanity). I havent played with pajes so dont know all that much about it. Looks rather like XMLC at first glance. As you mentioned, it can be annoying getting hold of the the various struts 'things' when doing a non-JSP approach - but they are all there and can be got at, and its not hard. btw: When working with beans (incl actionform) you will find that the stuff in BeanUtils is really useful for playing with properties whose name you only have at runtime. Heres some code that may help you get a handle on the essential struts objects: (I pasted straight from my StrutsHelper code and ripped out the irrelavent lines in case your wondering why everything has 'return' in front of it!) As you can see, pretty much everything has a key in the struts Globals interface. Chack the javadocs for this interface for more info. (The examples below are not fully module sensitive I think. (ie I havent tested it using modules)) ActionServlet: return (ActionServlet) servletContext.getAttribute(Globals.ACTION_SERVLET_KEY); ActionErrors: return (ActionErrors) request.getAttribute(Globals.ERROR_KEY); Locale: (hmmm. Not sure if using the default like that is std struts!) Locale locale = (Locale) session.getAttribute(Globals.LOCALE_KEY); return locale == null ? Locale.getDefault() : locale; ActionMapping: return (ActionMapping) request.getAttribute(Globals.MAPPING_KEY); ActionMessages: return (ActionMessages) request.getAttribute(Globals.MESSAGE_KEY); MessageResources: return (MessageResources) request.getAttribute(Globals.MESSAGES_KEY); ModuleConfig: return (ModuleConfig) request.getAttribute(Globals.MODULE_KEY); ActionForm: String scope = mapping.getScope(); //you need to get the mapping (see above) String attribute = mapping.getAttribute(); attribute = attribute == null ? mapping.getName() : attribute; return (ActionForm) viewContext.lookup(attribute, scope); hth Andrew -Original Message- From: Villalba Arias, Fredy [BILBOMATICA] [mailto:[EMAIL PROTECTED] Sent: Wednesday, 4 February 2004 20:40 To: Struts Users Mailing List Subject: RE: Struts and Pajes Ok. I'll try to be more clear: - I don't want to use JSPs when working with Struts, neither the Taglibs. Instead, I want to be able to delegate the presentation on an external component. - In order to do that, I must be able to access the data to be presented (i.e. access the appropriate ActionForm) from that external component, in consistency with Struts handlign of scope and other concepts. - It seems like Struts would expect you to (finally surrender and) use JSP + JSP tags, although it does not formally obliges you to do so. I've been checking both the source code for the tag libs and the .java-s generated by them and I get this strong impression that there is happening a lot more behind the scenes that one would suppose (and Struts would recognize). This would not worry me if there were Java classes that, not being JSP-oriented, still allowed me to do everything (or even 50%) Struts' JSP-tags do. I dont say they don't exist. I just have not found them. - I don't see why you say I'm conflating those 2 issues (please, explain it to me :) ). I'm not introducing anything new inside the framework, nor am I changing its normal behaviour. I'm respecting the roles assigned to each component. I believe what I'm doing is - precisely - prevent (or, at least, make it more difficult to) the developer from mixing control and presentation (on a JSP); moreover, I'm allowing the TOTAL separation of HTML and Java by encapsulating the dynamic generation of the view in a Java object especially designed for that purpose (for good). Anyway, I'm absolutely open to any comments / opinnions you can provide in this regard. IMPORTANTE NOTICE: I don't want start a discussion here about how good or bad Struts is: - I don't have time for that, - I don't have yet the required level of knowledge and expertise (on Struts, that is) to make such judgement, - That's not the point for this posting.

RE: what is controller servlet in struts framework
The controller servlet is the struts ActionServlet class. You configure this in your web.xml file so that it sends all requests whose path ends in .do (or whatever extension/path mapping you choose for your actions) to this servlet. The ActionServlet will actually make use of another class to do the bulk of its work when a request comes in (in struts1.1). This is the RequestProcessor. It examines the path and looks up the appropriate ActionMapping for that path that you have defined in struts-config.xml. From the information in the ActionMapping it determines which ActionForm class you want to use and in which scope it should be, creates an instance if necessary and populates it from the parameters in the request. Then the RequestProcessor will pass the ActionForm, and references to the request, response, and ActionMapping to the execute method of your Action class. (The first time this Action is used it will instantiate the action object. All subsequent requests in all threads will reuse the same instance that it created the first time). Your Action will (usually) return an instance of ActionForward, and the RequestProcessor will then forward the request to the path specified in the ActionForward (doing a client side redirect if the redirect property is true). In the event that an exception is thrown by your Actions execute method, and you defined an ExceptionHandler in struts-config.xml for it, the RequestProcessor will instead pass control to this ExceptionHandler. Basically the ActionServlet is the controller, but it delegates the processing of requests to the RequestProcessor. The RequestProcessor determines which Action should handle that request and calls it, so your Actions fit into the controller part of the MVC architecture along with the ActionServlet and RequestProcessor. (Other tasks of the ActionServlet include parsing the struts-config.xml file at application startup, and calling at startup any PlugIns you have configured). You may subclass the ActionServlet to customise its behaviour, but under struts1.1 this is less useful to do - in 1.1 if you need to customise that behaviour you would usually subclass the RequestProcessor. You can specify which RequestProcessor class to use in your struts-config.xml file. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Wednesday, 4 February 2004 22:58 To: [EMAIL PROTECTED] Subject: what is controller servlet in struts framework Hi guys I have been having a question.

IMHO contributing code to open source projects should also count for something in terms of experience - especially if its a well known project like struts. (If your still a student you should have a fair bit of spare time you could do that in too!). So why not take a look at the open defects and see if there is anything you can help with. :-) As for the experience vs no-experience problem, thats confronted graduates in all disciplines since time immemorial! Just got to keep trying till you can get your foot in the door somewhere (dont be surprised if you end up in a completely different area of IT than what you studied!). Once you have some experience under your belt the number of options available to you expands tremendously. As for overseas markets, can't give any advice on the States, but the job market for programmers here in S'Pore is dead as a dodo (supply exceeds demand and starting salaries are dropping dramatically). Your probably better off staying in Sydney. Tax is much lower here though, top marginal rate is something like 26% when your earning 400k.

I have discovered that when I use patterned solutions I get benefits I did not think of at the time. This is particularly true of the HTTP version of the MVC framework. At 09:35 PM 2/4/2004, you wrote: My perspective is that there is still value in having an ActionForm for that example. I generally think it is best for your Actions to pass information to the JSPs that render them through an ActionForm rather than putting things in the request or session directly. For this reason, I think it would be better to put the current time into an ActionForm than to stuff it into the session. Struts will put your ActionForm in the request or session for you; your Action need only populate it with data, and then the JSP can expect to find your well-defined ActionForm in the scope specified in the struts-config.xml file. It doesn't matter if there is no data coming in on the request for Struts to pre-populate the ActionForm. Using an ActionForm still has value in that it defines what the JSP can expect to find, and where. Opinions on this topic surely vary (i.e. I am sure some people will disagree with my recommendation here), and I have seen a lot of Actions and JSPs that communicate via request and session attributes that aren't defined in the struts-config file. But I prefer to limit the communication between the Action and the JSP to a well-defined ActionForm in a well-defined scope to the extent that it is possible. I view the Action/JSP coupling that comes with passing otherwise undefined request and session attributes to be undesireable. I think it is better to keep the interface between these components (a specific ActionForm in a specific scope) well defined (by specifying it in the struts-config.xml file). -Max - Original Message - From: Masashi Nakane [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, February 04, 2004 5:00 PM Subject: Action without ActionForm Hi ,all I am new to Struts and learning it.

RE: Need to pass data to JSP in ActionForm
If the list doesnt change during the course of a users session then the best thing to do is to create it on first demand and store it in the session. This saves you from looking it up from the db repeatedly when unnecessary and is thus more efficient. If the list is the same for all users and doesnt change at all then you could store it in the servlet (application) context. If it does change (for example when new records are added) then you will still need to look it up each time. In this case your best bet might be to extend Rick's suggestion about having a seperate helper class that assembles the list (always a good idea). This helper/manager/thing is part of your business process layer. Above that you could have an aditional (very simple) adaptor class that is passed a request, calls this helper to obtain the list, and stores said list under the appropriate request attribute. Your validate method could thus call this adapter to setup the list when it is validating the entered data. Your setup action, likewise would call the adaptor class rather than directly calling the business layer and storing the result. One thing to beware of when you do such non-trivial things in the actionform, is that if memory serves me correctly (someone please correct me if Im wrong on this!), exceptions thrown here wont be handled by the exception handler you configured in struts config as the try/catch that invokes that handler is merely around the invocation of the actual action execute and not the form reset / validate stuff. These are some of the reasons I personally prefer to do my validation in the action itself and dont make use of the forms validate method. (Of course if your using struts validator that becomes problematic too) hth Andrew -Original Message- From: Rick Reumann [mailto:[EMAIL PROTECTED] Sent: Wednesday, 4 February 2004 12:26 To: Struts Users Mailing List Subject: Re: Need to pass data to JSP in ActionForm Pat Young wrote: 6. The problem I am having is that if the ActionForm failes validation, then the sales.jsp page gets an error becaue it can not find the bean in the Request for the products list. Should I build this bean in my validate and place it in the request at the beginning of validate? If validate fails, there is no other opportunity to build the products list and get it into the Request. Personally I often opt for the easy solution and put the List in Session scope, but there are other alternatives that have been discussed on this list before. 7. I typically uses Actions to retrieves and build beans and then add them to the request for the jsp to access. Is this an acceptable practice also? Depends what you mean by build beans. Nothing wrong wtih setting stuff into Request scope from your Actions, but make sure you are calling some business process that does the actual building. For example... //in your Action: List someList = someBusinessClass.getMyList(); request.setAttribute(listWhatever, someList); -- Rick - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Yeah.

RE: Email with file created on the fly
1. Create the file 2. Email it (duh!) Struts is a web ui framework. It's not about email and all that, so its not really a question of how to do it 'with struts', but more a case of *where* to do it in a struts app - and that depends on when your sending the mail (interactive or batch). Go take a look at the JavaMail api if you want to know how to send an email. If you have any issues with sending this mail that are related to struts then come back and ask questions, but you will need to make more effort posing your question than you have so far. I mean you havent even stated what the scenario is. How do expect to get an intelligent response like that? Is the email sent as a result of a form that has been submitted or is it a batch email sent at a set time or some kind of alert email that gets sent when something happens in the system?

RE: [OT]caching XML object
Im not familiar with JDOM, but Ive had to do some DOM caching for standard DOMs (with Xerces DOM impl) which proved to be a pain, as xerces DOM objects arent thread-safe - even for reading apparently - which meant I had to clone it from a synchronized block (thus eliminating most of the benefit of caching it). Not sure if JDOM suffers such a constraint though. What is the XML object being used for? There may be better ways around your problem that dont necessarily involve directly caching and comparing the XML. -Original Message- From: Prashanth.S [mailto:[EMAIL PROTECTED] Sent: Friday, 30 January 2004 10:45 To: [EMAIL PROTECTED] Subject: [OT]caching XML object Hi all, How can i cache XML object in my web application?I dont want to always read the xml file for constructing XML objecti also need a way to check weather there has been any changes between the existing object in cache and xml file???Iam using jdom Thanks Prashanth - Do you Yahoo!?

RE: constant url
Yep. Basically while your html UI is there to 'help' the user send the right parameters in the request you cant ever rely on it to do so. It is quite technically possible for the data to be sent to you some other way (and this could be legitimate - for example someone using HttpClient to write an tool to automate something that is normally done through your html ui), so basically you have to be prepared to validate any requests and associated parameters that come in, and not rely on the form or html to have done this for you (except as a convienience in terms of useability). You need to check any data sent to your app before using it to make sure it isnt going to break the app. In terms of security and hacking you need to make use of traditional methods. Sessions and url hiding alone dont ensure security (someone with a packet sniffer could sniff the sessionId and hijack the session with spoofed packets), etc... For proper security you need SSL of course - which means that the contents of the request are encrypted between server and browser. -Original Message- From: shankarr [mailto:[EMAIL PROTECTED] Sent: Tuesday, 27 January 2004 18:32 To: Struts Users Mailing List Subject: Re: constant url Hi!
