Re: How to pass Session variable to different Webapplication?
You can also use JMS to pass an object through a messaging queue. OpenJMS is an open source JMS Engine that works well for me. I have not played with to many of them to know if there is a better one out there (for free). All of the major Application servers (BEA, WebSphere, etc) support the JMS spec.

Re: Who decides?
Just to put in my 2 cent worth, I am not sure your point is 100% valid. True, languages and technology is changing daily and what you learn today is worthless in 10 years from a coding language standpoint, but being a senior developer or architect is very different than being a coder. Some key things that are learned from experience: 1. Just because a new technology is hot in the industry, it is not necessarily right for your organization. Many young talented developers will attempt to change the environement to what they are comfortable with, not what is the best fit for the company. I have seen a lot of good developers attempt to write php or _javascript_ functions because they know how, but do not consider what the impact of that decision is. What is the impact on the server? What is the impact on the client? How maintainable is it if they move to a different projeect? etc. 2. Depending on the background of the developer, many younger (I sound old) developers may not have been exposed to the various stages of the production life cycle. They may work well on new projects, but not work well under the pressure of a major production outage. Others may have spent years developing updates to legacy systems which and not been exposed to new development. Adding one of these developers to a new project, most will attempt to impose what they know on the problem and not look at what is best. 3. New technology geeks (self imposed title), often know a technology or a suite of technologies. They are truely excellent programmers, but do not understand business. (Welcome to the 2000 .bom explotion). Just because something is a great idea, does not mean that it is a good business decision. Just because you can do something, does not mean that you should. User interface design, Business Process Optimization, Change Management, these are soft skills that are required for a lot of companies. 4. When looking for senior level developers, architects, etc, you need a developer that has been exposed to more than just one method of development or one environment. Someone who truely knows that there are many ways to solve a problem and knows how to find the right implementation. They need to be able to think for themselves, not just code to what they know or want to know. Yes technology changes, but good practices, design knowledge, and research skills are all tools that are developed over time.

Re: Prepopulating DynaValidatorForm and validating
I have handled this in two different ways.
1. Previously I had a preprocess action which populated the collection and that was all it did. In the struts-config, I set the preprocessAction.do as the input page. That way if the validation failed, struts will execute the preprocessAction which will repopulate the list and redisplay the form in tact.
2. Resently, I have been using DWR (Ajax) project to load the select list when the page is rendered. I do this because my list is dynamic and can change based on selections that the user enters on the page.

Prepopulating DynaValidatorForm and validating
Hi all!
Googling and seraching the archive did not solve my problem, so
I will have a try. In my struts-config.xml, I have defined a
DynaValidatorForm and an action:
form-bean name=editForm
type=org.apache.struts.validator.DynaValidatorForm
form-property name=projectList type=java.util.Collection/
form-property name=version type=java.lang.String initial=/
/form-bean
action path=/processEdit
type=com.materna.buc.buildmanager.actions.ProcessEditAction
scope=request
name=editForm
validate=true
input=/WEB-INF/jsp/edit.jsp
...
/action
As you can see, this form holds a list of projects in a collection,
which has to be populated before the corresponding jsp-page is shown.
So I have an Action which gets the (dynamic, not static) list of
projects from a database and puts it into the editForm like this:
public ActionForward execute( ... ) {
DynaValidatorForm dynaForm = (DynaValidatorForm) form;
// get list of projects from database
Collection projectList = getDatabaseHandler().getProjectList();
// put project list into DynaValidatorForm
dynaForm.set( projectList, projectList );
Everything works fine after showing my jsp-page with a combobox
populated with the data from my projectList - the user can choose
one project.
But on the same page there is a html:text field:
html:text name=editForm property=version
value=1.0 size=7 /
which corresponds to my editForms version-property.
When the user submits the form to processEdit, the version
property has to be validated to see if it is not empty.
So in my validation.xml I do the following:
form name=editForm
field property=version depends=required
arg0 key=edit.version /
/field
/form
If the user submits an empty version and validation fails,
he will be send back to the jsp-page, but it will not show
because the project list is not present any more. That seems
clear because the DynaValidatorForm is reset when the user
submits. I tried following workarounds:
1. I replaced the DynaValidatorForm with my own version
overwriting the reset - method to do nothing. Additionaly
set the scope to session. But my project list gets still
lost (wondering why?)
2. Trying to pass my project list from one form to the other
like this
html:hidden name=editForm property=projectList
value=projectList
in all variations always had to fail because the project list
will be send as a string and therefore can not be converted
back to a collection.
I considered to put my project list into application scope, but
as it is dynamic, large and not the only (dynamic and large) list
to be shown on my jsp-page (I only used it as an example in order
not to complicate my question), I am not sure if it is the right
way.
And writing an ActionForm with own validation and reset methods
is a lot of work and would not use the benefits of a
DynaValidatorForm...
So if you know a trick, solution or workaround, please help!
Thanks

Re: request attribute in jsp - please advice
if you store the request attribute in a hidden field on the screen, when the page is submitted the field will be put back into the request. Otherwise, you will need to move the field to the session where it will not be cleared when the request is invalidated after the JSP is displayed.

request attribute in jsp - please advice
Hello friends
I have an EditStudent.jsp page in which I have a form. Before the form
tag I get a request attribute called 'listIndex'. But, when my
validate() method fails on field validation it returns back to the above
mentioned jsp page with an appropriate message. That is o.k. - the
problem is that this causes the removal of the request attribute that
was originally set by the EditStudentAction.
So what I do now in the jsp page is something like this:
% int listIndex = 0;
If (request.getAttribute(index) != null){
listIndex = request.getAttribute(index);
}else{
If (request.getParameter(myIndex) != null){
listIndex = request.getParameter(myIndex);
}
%
And then under the html:form I have an hidden input like:
INPUT type=hidden name=myIndex value=% =listIndex%
When the validate{} fails the - getParameter(myIndex) - enables me to
restore my request attribute via the hidden parameter.
Do you know a nicer way to do it?
Thanks

Select Options Question
I am sure there is a slick way to do this, but it escapes me at the moment. I have a Select Box that I am populating with the html:options tag The result is: select name=cmbGroup id=groupList option value=jk12341Group 1/option option value=34t1fv1Group 2/option option value=32fq21Group 3/option ... /select I need the value for DAO actions performed from the search which will return a detail bean for display on an output JSP. On the output JSP I need to Display the Group Name that I selected from the input. My Form holds the group id and a field for the group name. The options that I can see are: 1. Requery the Database for the output page to retrieve the name given I have the key. This would work, but seems like a lot of overhead to go to the database each time. 2. Create a delimited value (ie option value=jk12341, Group 1Group 1/option) and use the String Split to get the value and label. (I am leaning toward this) 3. use javascript to update the field each time the select changes. The problem with this is that the select box can be very large based on the users selections on previous entries. 4. Store the Value Label list in the session (Don't like this at all because the volume of users that will use this application). Any other suggestions?
Re: Select Options Question
On the result page I only need the Label for the selected option. Not the entire list. The problem is that when you submit the form, you only submit the value in the form object and loose the label. I need to pass the label as well so that I do not have to requery for it. The way that i have it currently is that the value contains a comma delemited string containing both the label and key (overkill on the bandwidth I know). In my action class, I do a string.split on the comma and pass the first value to my DAO processor and the Second value I put in my form for display. It is the only way I could think of without iterating through the options or storing the initial results which populate the option list. Frank W. Zammetti [EMAIL PROTECTED] Frank W.

If you just need the grou pname, could you simply put the group name in session? May or may not work depending on the flow of your app, but it would be a nice, simple solution if it'll work... just remember to clear it out at an appropriate time. The other option that comes to mind immediately is indeed to use _javascript_... seems like all you'd need is a form with two hidden fields, groupName and value... onChange of the select, populate those two fields and submit() the form.

RE: Passing variable to _javascript_ function
Unfortunately it's not so easy, because you can't use a tag as an
attribute to the tag.
html:link action="" name=deleteDataParams scope=page
validateDelete(bean:write name=data/)
This can't work, because the attribute (onclick) will not be evaluated.
There could be two possible solutions. First, leave the html taglib and
drop back to normal a href...
Second: store the variable value in a _javascript_ variable:
script
var myData = 'bean:write name=data/';
/script
html:link action="" name=deleteDataParams scope=page
validateDelete(myData)
Of course this only works if you have the value of myData at page
generating time. If the value is changed by something the user does on
page, like checking a checkbox, i would store it in a hidden field in
the form and read per _javascript_ in validateDelete(), like this:
for (var i=0;i document.formname.elements.length;i++){
var e = document.formname.elements[i];
if (e.value == 'set' e.checked==true){
doSubmit=true;
myData = e.value;
}
}
the above _javascript_ is only an example how to iterate over form fields
with _javascript_, it has not the required functionality.

Leon

Re: core struts -- best practise fundementals
For the most part you are correct. However, it is a little more straight forward than that. Logic should be wrappered in a logic object. The Tag Library can bridge the presentation to this generic logic. This is so that the generic logic can be used universally from either a presentation screen or from another logic object that needs the same functionallity. This is good practice because it allows you to write the code once and reuse it in many places. This saves on memory, Maintenance time, Development time, etc. The reason you want to extract presentation from logic, is because many companies rebrand themselves often on the internet. New look and feel keeps thing nice and fresh, but is a nightmare if you have to rewrite your applications just to take on a new layout. Additionally, after a site is released, you often find the users do not use the application as you expected during development. By rearranging the screen layout and application flow, you can make the users more productive and generally happier. If you tie your logic to your screen this becomes much more complex. The key to any object oriented language is to develop small compartmentalized objects. These objects should focus on just the functionallity it needs to complete its task. A fell defined set of interfaces should handle getting the information to and from the little back box. This is where Struts, Taglibraries, JSF, etc come into play. peru cheppanu [EMAIL PROTECTED] peru cheppanu [EMAIL PROTECTED] 08/29/2005 12:41 PM Please respond to Struts Users Mailing List user@struts.apache.org To user@struts.apache.org cc Subject core struts -- best practise fundementals Hi all, I am trying to understand the motivation behind seperation of logic and presentation in struts framework. I was wondering if any of you can provide some light if I am thinking in right direction. Now, if you write scriptlets in JSP, that is a bad practice.., however if you hide that functionality in a tag class and implement that tag like struts tags or any other tags.. thats a good practice. For example, I want to send a concatenated string instead of a hashmap to display as per key-value relationship. I meant send [EMAIL PROTECTED] string rather than a hashmap and want to parse it for display. If I write a scriptlet that I use to substring and display only that user is concerned with -- that is bad practice. If I use a tag lib that looks more like logic:substring name=hashArr digits=4, -- good. Am I getting this whole thing wrong?

Re: Can nested tile layouts be done?
It can get a little difficult to keep up with. Basically, you have to know the Hierarchy of your tile and call the top most one. In this case, you would call .base which would intern call myEndUserPage.page1 and finally myEndUserPage.jsp. to change to another.jsp you would call .anotherPage in your action forward. Nesting tiles can be very useful when switching components of a tile, but can quickly become a headache when changing tiles in both layouts. I use the nested for menus only and have been debating on switching to struts menu because of the complexity. The only thing that has prevented me from doing this is waiting to see if I can jump to JSF or AJAX/D-HTML instead.

Thanks, I think this is better. I still must be missing something about how Tiles works internally, though. In my app, the tiles definition for the end user page (the one that defines body) is called endUserPage.tiles and Tiles is smart enough to handle requests for endUserPage.jsp in the correct tiled way. You have this arranged differently, where the end user page definition has a more cryptic name (.myEndUserPage.page1) and is referenced by .base.

Re: Nice try (was Java code generator including Struts 1.2)
I have used code generators in the past. True they can save initial development time, but many have serious short comings. (Not that this one does as I know nothing about it, but in general.) 1. The code is lowest common denominator code. Meaning that the generated code could typlically be optimized for the specific situation that it is generated for. 2. Depending on the programatic structure of the generator, the code can be very difficult to read for future maintenance. 3. Management often mistakes having a code generator can replace experianced programers and save big $$$. What usually happens is that the more the company invests in generated code, the less the developers know, the poorer the application design, the more you need experianced programmer to tell you why you are having performance problems. (The same argument can be made for intellegent IDE's which is really all a code generator is). 4. The generator itself can outdate itself very quickly, locking you into old technologies. For example, this email indicated struts 1.2, which version? 1.2.3, 1.2.7? Also, is this for java 1.5, 1.4, 1.3? Companies the size of IBM, Borland, Sun or open source sites like Jakarta have the resources to keep their software/frameworks up to date with technology, startup companys or school projects don't have that luxury. So, where I like the Idea of a generator for speed, I have difficulty accepting the cost.

WebSphere Application Developer has a Struts Diagraming tool that will let you create a skeleton struts application using drag and drop. It does very well. It will populate your struts-config.xml and create skeleton JSPs, ActionClasses, FormObjects, and the like. No actual code generation, just the shell. If you are looking for something a little more robust, the Rational rapid developer will do the same thing using UML and will Shell out you application based on your model.

Re: What is the recomended framework
I think the true answer to that question is it depends. What is your tolerance for new technology? What is your expectation for integration with older systems? What is your developer experiance base? etc Personally, if I were starting a project from scratch with no chance of integration with applications of another framework, I would be fooking at JSF as the foundation of my project. This is because it is an accepted standard for the new JVMs. I would probably look at spring or shale to simplify some of the monkey work. The dangers on this implementation are: a) Finding a large support base for this technology as it is new and has less implementations than legacy architectures like struts. b) Finding competent developers if the project is large enough to have multiple developers for the same reasons as A. c) Requires 1.4 or higher java. I personally do not have a problem with this, but a large company (I know several) may still be running 1.3 for many of their legacy applications and are not willing to move to 1.4 or 1.5 d) JSF does not have the proven implementation for large scale, high traffic, high volume web applications yet. (At least I do not know of one). I am talking about the 10,000+ simultanious users with 100,000+ transaction per hour range. I think the technology can handle it, but it would require a lot of scalability testing on my part before I released a new application under these conditions. e) Not as much open source code bases to pull from. Could affect time to market. However, I do feel this is the way the web app market is moving, expecially in combination with Ajax for the user interface (Which JSF has some nice integration packages already).

Struts Validator w/ Modules
Hi everyone, I am having difficulty getting validator to work with my module based struts application. I have tried serval approches to no avail. My Struts Config and module config have: plug-in className=org.apache.struts.validator.ValidatorPlugIn set-property property=pathnames value=/WEB-INF/validator-rules.xml,,/WEB-INF/validation.xml,/WEB-INF/module/validation.xml/ /plug-in My /module/validation.xml has: form-validation formset form name=formName field property=fieldName depends=integer arg0 key=label.fieldName resource=com.module.resources.module/ /field /form /formset /form-validation If I use client side html:javascript formName=formName It does generate the script with all validations listed in the xml. so I think that the Plug-in is correct. I would use the client side script except it generates incorrectly. It creates methods like formName_IntegerValidations() but the actual validateInteger calls for just IntegerValidation() (No formName). If I use client side, it never calls the validations. I have also tried using: form name=/action and form name=/module/action with no difference. Any thoughts?

I would recommend changing the capital T to a lowercase t. This is standard. I have had problems in the past with having uppercase variable names. This is due to the reflection that Struts uses to find associated getters and setters.

Sounds like you probably have a case problem.
Please make sure that you reference Title with the capital T throughout

I can see your set method references title with lower case, this is
probably the culprit.
Hope this helps.

Hi Johnson,
I am vary sorry for mailling on your personal email address.I had
posted my problem on the mailing list but till now don't get any
reply. If you have time plz take a look.
I am new in Struts framework. I had created simple Form
containging 2
members variables as
Form1
{
String Title;
Collection col;
}
I had created getter setter for both the members.
Now in my jsp page
I had coded like html:form action="">
( DisplayGraphStep2 is linked with the above Form1.)
Now
if try like html:text property=col/ then it works
but i try for html:text property=Title/ I get an exception ;
Root Cause -
javax.servlet.ServletException: No getter method for property Title of
bean org.apache.struts.taglib.html.BEAN

Error Message Problem (Again)
Hi All,
Seems this is a constant area of irritation. I am attempting to put an
error message into the ActionMessage in an Action Class and redisplay this
on a JSP page. This application is using tiles and is located in a Struts
Module. Seems simple enough, but I can't get the darn thing to display on
the JSP.
Here is extracts from my code.
Action Class:
public ActionForward execute(final ActionMapping mapping,
final
ActionForm form,
final
HttpServletRequest request,
final
HttpServletResponse response) {
ActionForward forward = mapping.findForward(fail);
ActionMessages errors = new ActionMessages();
...
errors.add(displayerror, new ActionMessage(myerror, false));
...
saveErrors(request, errors);
}
JSP Page:
html:form action=/myAction.do method=post
html:messages id=error property=displayerror
bean:write name=error /
/html:messages
...
/html:form
I have also tried:
html:form action=/myAction.do method=post
html:errors/
...
/html:form
Neither work
I inspect errors on the save error line and can see the error message in
the ActionMessage list, so I know it is being added to the request. I also
used the false attribute to simply display myerror on the page to
eliminate the possibilty of a properties file typo problem. Any
recommendations on where to look?
RE: Error Message Problem (Again)
No luck.
I also added test inside the logic:messagesPresent ... tag. The text was not displayed which indicates the save did not put any messages into the request, Yet, the ActionMessages does have a message in it and the saveMessage(request, errors) line is called.

Hi,
Try the following:
Use saveMessages(request, messages) instead of saveErrors(request,

And use something like

Hi All,
Seems this is a constant area of irritation. I am attempting to put an
error message into the ActionMessage in an Action Class and redisplay
this
on a JSP page. This application is using tiles and is located in a
Struts

on
the JSP.
Here is extracts from my code.
Action Class:

ActionForward forward = mapping.findForward(fail);
ActionMessages errors = new ActionMessages();
...

JSP Page:
html:form action="" method=post

I have also tried:

Neither work
I inspect errors on the save error line and can see the error message in
the ActionMessage list, so I know it is being added to the request. I

Re: [Tiles] Sharing Context Between Two Tiles
Portlets are java mini applications that work within the Java Portlet Specification. They are ment to run using a Portal Server like Websphere Portal server, Metadot, or jetspeed. These 'applications' can share variables, etc via the Portlet container. The container manages the placement and look and feel of the applications in a simular fashen to the tiles layout, but come with a overhead cost. (I would venture to say much larger than the tiles overhead).

Re: [Tiles] Sharing Context Between Two Tiles
Basically that is the way you do it, although I'm not really sure from
your description that I know why you thought you could achieve what it
looks like you were attempting.
A question for you that bugs me everytime I see 'portlet' come up: what
on earth are portlets? Are they meant to be a different technology to
'servlets'? Surely not, as you are using JSPs.

Hello All,
I'm trying to write a portlet like component using tiles. A simplified
version of my first attempt follows:
The portlet definition:
definition name=.uicomponents.portlet
path=/tiles/uicomponents/portlet.jsp
put name=content/
/definition
portlet.jsp:
[...]
div class=portletStyle
tiles:insert attribute=content/
/div
The definition for a particular portlet:
definition name=.portlets.oneportlet
extends=.uicomponents.portlet
!-- For this definition we're going to use this JSP as
the portlet content... --
put name=content value=/portlets/oneportlet.jsp/
!-- We're also going to define a parameter that is
required by oneportlet.jsp --
put name=aParam/
/definition
oneportlet.jsp:
[...]
tiles:useAttribute id=aParam
name=aParam classname=com.mycompany.SomeClass/
c:out value=${aParam.someProperty}/
Finally a body page that inserts oneportlets:
[...]
c:forEach var=someClass
items=${requestScope.collectionOfSomeClasses}
tiles:insert definition=.portlets.oneportlet
tiles:put name=aParam beanName=someClass/
/tiles:insert
/c:forEach
Upon trying this I found that aParam is not available to oneportlet.jsp
(attribute not found error on tiles:useAttribute). I did find that
aParam was available to portlet.jsp. From this I realized that my
tiles:insert in portlet.jsp was creating a new tile context for
oneportlet.jsp, and the fact that my .portlets.oneportlet definition was
extending .uicomponents.portlet did not mean that their context would be
shared.
The only solution I've been able to think of so far is to add a generic
attributes attribute to my base portlet definition, and just pass that
on the insert of the content defined by the extending definition:
The new portlet definition:
definition name=.uicomponents.portlet
path=/tiles/uicomponents/portlet.jsp
put name=content/
put name=attributes/
/definition
The new portlet.jsp:
[...]
div class=portletStyle
tiles:importAttribute name=attributes/
tiles:insert attribute=expandedContent
tiles:put name=attributes beanName=attributes/
/tiles:insert
/div
My body page has to build up a collection of all the parameters that
oneportlet needs (either from the action or using scriptlets), and
oneportlet has to iterate through that collection pulling out the
parameters it needs. It's hard read and maintain.
So thanks for listening to this point, and now for my question: can
anyone think of a better approach? My next attempts were going to be
seeing if a tiles controller for .uicomponents.portlet could copy it's
context to the inserted content, or trying a JSTL import instead of a
tiles insert and seeing if the portlet's tiles context would be
available to the imported page. Is there an entirely different way to
look at this that I'm not thinking of?
Thanks!

Re: Struts + JavaScript = dynamic forms
There are several ways that this can be accomplished. 1. Pure Struts. You can create an Initialization Action which holds you form as the input form. When you change select 1, in the onchange submit the page to the init.do. the page will retain all input values as the form will maintain your entries. The problem is that the page will noticably flicker. 2. Pure _javascript_. Down load all options and used _javascript_ to change out the values. Downside, you have a larger page to download (_javascript_) and you have to download all possible options, many of which you will not need. 3. AJAX. The new kid on the block. The Onchange will run a java mthod which will connect to the server and return the updated options. Check out DWR or equivalent. I am sure there is a JSF or PHP solution as well but I am not familar enough with those technologies to comment. All three of these options will use _javascript_ to some extent and if someone has _javascript_ disabled, this will not work.

Re: JSF is the beginning of the end of Struts !!!
I am the same way. I have a large collection of common libraries that I have developed over the past 5 years or so. Each iteration, they get a little more powerful. I can create a highly scalable and complex application very quickly using Struts because of this. Yes java may be overkill for a personal home page, but for mission critical applications or sites that require 1000's of transactions per hour, it is a must. I hope JSF takes off and becomes as easy to use as VS 2005, but until a wide range of either customer components or vendor developed components are available, its reach will be limited by comparision. I think it will happen, but not over night. Until then, there are very few languages that can deliver the power and speed of development as my struts / Java library.

Re: Actions forwarding to actions
Not always. An Action should be created to perform a specific control instance. For Example, if you are going to insert a record, the Action class has all the required code to insert the record. However, as you get into more complex systems, you will often find that you are duplicating a lot of the same functions. At this point you have to abstract many of these functions into utility or helper classes to reduce the amount of duplication that you have. This reduces your action class down to simply flow control logic. But if this becomes highly repetitive, then you may breakout into calling multiple actions that know how to handle a specific set of events.

Re: Design question
I think you are re-inventing something here.
To do what you are wanting is already in struts to some degree.
you have your User Bean, You define an formbean which either contains UserBean or contains fields that match UserBean
on your jsp page you create something like
html:html local=true
html:form action="" method=post
bean:message key=resource.key/html:text propery=userId/
/html:form
/html:html
This will print the UserID's label from the Resource file and give you internationalization.
This might be easier than embedding HTML into a tag or bean.

Design question
Hi
I'm interested in yours opinions about following design approach. I'd
like to create some kind of view beans for viewable model beans. Those
view beans can generate HTML for attached model bean. This generated
HTML is based on resources, so I am able to generate different HTML code
depending on session locale.
Lets say I create one model bean User
I created UserView with reference pointing to User.
I attached reference to MessageResources in UserView bean during action
execution with getResources(request)
In my JSP I added: bean:write name=UserView property=content
filter=false/ which calls getContent() method
UserView method body is:
public String getContent()
{
return messages.getMessage(user.login)+user.getLogin();
}
where:
messages - private UserView member of class MessageResources
user - private UserView member of class User
user.login - resources key
Everything worked well, but when I changed session locale my UserView
bean generates output for previus locale. I think that I have to update
messages member of UserView bean or use reference to other object, maybe
servlet which will be constant during session.
I'm new to struts, so I'd like to know if there are some other issues
connected to mentioned design and struts?
Regards

Re: Design question
There are several possibilities to do what you are asking. You will still have to modify HTML code, it is just where. I would not typically create multiple jsp pages for Add, Update, Display. I would create a single page using a DynaValidatorForm. this way you can use the same form and based on the action you call, the appropriate validation will be performed. Additionally, I would look into the CRUD Action Examples to prevent me from developing multiple actions. Based on the funtion you are calling the appropriate Data Access function can be called. If this is set up properly you can get away with changing only two components for this to work the Business Object Bean and the HTML page.
Granted, if you have this information on multiple pages like a login page, then as a display in the corner of each page within the application, you would need to update that on each JSP page. But it is likely you would want to do that anyway to insure the look and feel of each page.

Re: Design question
Well, I thing about something else.
If UserView bean can generate HTML form fields dependig on User
attributes, one for adding, another one for editing I could only change
my User bean (model) and my view layer will work without change. I think
that it is possible to write action that will work with this (controller
layer) without change too.
Lets say, I add new attribute to User, eg. lastName.
I have to:
1. modify User bean code (model)
2. then modify appropriate jsp pages, first with edit form, second with
add form
3. then modify struts-config.xml (form properties)
4. then modify appropriate form bean
5. then modify two actions (one for edit, one for add operation)
It would be nice, to change only my model and have view layer adapting
to model.
Mabe I'm re-inventing the wheel. If so, please tell me. I'm new to
struts and Java technologies, just trying to make right decisions before
my projects start.

I think you are re-inventing something here.
To do what you are wanting is already in struts to some degree.
you have your User Bean, You define an formbean which either contains
UserBean or contains fields that match UserBean
on your jsp page you create something like
html:html local=true
html:form action="" method=post
bean:message key=resource.key/html:text propery=userId/
/html:form
/html:html
This will print the UserID's label from the Resource file and give you
internationalization.
This might be easier than embedding HTML into a tag or bean.

Design question
Hi
I'm interested in yours opinions about following design approach. I'd
like to create some kind of view beans for viewable model beans. Those
view beans can generate HTML for attached model bean. This generated
HTML is based on resources, so I am able to generate different HTML code
depending on session locale.
Lets say I create one model bean User
I created UserView with reference pointing to User.
I attached reference to MessageResources in UserView bean during action
execution with getResources(request)
In my JSP I added: bean:write name=UserView property=content
filter=false/ which calls getContent() method
UserView method body is:
public String getContent()
{
return messages.getMessage(user.login)+user.getLogin();
}
where:
messages - private UserView member of class MessageResources
user - private UserView member of class User
user.login - resources key
Everything worked well, but when I changed session locale my UserView
bean generates output for previus locale. I think that I have to update
messages member of UserView bean or use reference to other object, maybe
servlet which will be constant during session.
I'm new to struts, so I'd like to know if there are some other issues
connected to mentioned design and struts?
Regards

Re: Technique for undetermined time of processing - progress bar
I use AJAX to kick off the process. For this case You can send an AJAX request to get the time, once recieved display a div that will contain the progress bar and submit a second request to run the actual process. On completion, you can forward the page to the next url. If you use DWR and can just display an anamated gif or flash movie, then you can use the built in pre and post process hooks. The preprocess would display the image and the post would hide it. on completion of the process have the page submit to the next screen.

Re: instantiation of actionforms in session scope
In the case you outlined, wizardForm should be placed into the session scope when leaving the Funds action. You are not required to use the struts tags to access the data, but if you are using the struts html tags for input etc, you will need to use the html:form tag. If you are not using the struts tags, you should still be able to use the form bean with a standard jsp:usebean id=wizardForm scope=session You should also be able to access it from other action classes by explicitly calling the getAttribute(wizardForm). When you say that it is instantiated with every new page, how are you attempting to access the bean?

html:select Problem !!
Hi all,
I want to set records come from database into a html:select tag. I found some example like below
html:select property=selectedItem
html:options collection=customers property=id labelProperty=name /
/html:select
When I set th options as static , the list comes without any problem. But when I create a html:select dynamicly from DB , I get error.
In my Action class, it has a method called getSikayetler() like this.
Sikayet sikayet = null;
ArrayList sikayetler = new ArrayList();
while (rs.next()) {
sikayet = new Sikayet();
sikayet.setSikayetKodu(rs.getString(SIKAYET_KODU));
sikayet.setSikayet(rs.getString(ACIKLAMA));
sikayetler.add(sikayet);
}
When I created an ArrayList, I send it to my Action class and in my Action class I set this ArrayList to request like below
ArrayList listeDondur = getSikayetler();
request.setAttribute(sikayetler, listeDondur);
sikayetler ArrayList is not null and empty, I tested it.
How must I use this request object called sikayetler in html:select ?
html:select property=tumSikayetler
html:options collection=sikayetler value=sikayetKodu label=sikayet /
/html:select
usage of above is wrong?
In Sikayet class there are get and set methods like sikayetKodu and sikayet .
How can I fill html:select tag with records coming from DB?
Any help, sample codes?
Thanks

Re: Paging in DisplayTag
This is dependent on how you have structured you database query. There are multiple solutions to what you are attempting to do. 1. Create a query that will return the entire resultset and store that resultset in the session as you metion. If you are returning an extremely large result set, running the application in a clustered environment with percistant sessions to a database, or have a large number of users, this could prove problematic. The more you put into the session, the more memory your application will use. Additionally, if you persist your session, you are requerying each time you mention a session. This could be a mojor performance hit. Finnally, you are moving a lot of data across the network. If 90% of the users will find what they need on the first 1 or 2 pages of a resultset, pulling back the data to populate the reset of the menus is a waste of resources. 2. If all users are going to use the same resultset (ie multipage menuing or a product catalog), this may be a occation for a singleton class with a collection containing the data. You could refresh this singleton based on a timeframe to insure it remains current. this will only work for semistatic results. 3. Implement a fast lane reader pattern. This will subdivide your SQL results to return only the page that is being displayed using boundry conditions in the SQL or Stored procedure. This will require a database hit between each page, but if the database is properly indexed and you are using a connection pool, you can still retain very fast performance. I am sure there are many more ways to address this problem, but these are the three that I have had the most experiance with. It boils down to ever situation is different and you have to customize your solution based on the data, the business requirement, and the user habits.

Typically, I will create a SearchBean with all of the search parameters on it. Included in this bean is a collection to store the results in.

Take for example an advanced search page with validation, drop down lists, the works. Upon successful validation the user should flow to a search results page. Assume the results page is part of something bigger that may require additional server-side processing. In the past I have put the search results list on the same action form as the search criteria and just forwarded to a different JSP from the same action. There are times when I would prefer to forward to a different action/form pair, especially if their is potential for additional processing.

Is there an elegant way to do that in Struts? Am I just trying to make this overly complex?

Struts Tiles Question
All, I am using Struts Tiles to layout my site. I have a vboxmenu design which contains 4 menu levels: definition name=doc.menu.main path=/common/jsp/layout/vboxLayout.jsp putList name=list add value=common.menu.home / add value=common.menu.authenticated/ add value=common.menu.admin / add value=common.menu.logout / /putList /definition I am wanting to control when the Authenticated menu and the Admin Menu are displayed. For example, only display the admin menu if the user is in the Admin Role. I know that the taglib tld has a role attribute, but the dtd for tiles-def does not. Has anyone created anything simular with tiles?

Re: Newbie: Where to put instance for database access?
Depending on the level of usage to the database, I would recommend implementing a connection-pool and requesting a connection each time you need to query the database. If you hold a single connection for your application, you will limit your scalability and hurt performance based on the user load. How you set up this pool is dependent on the database you are using and the resources you have available to that database. I would recommend looking at the Jakarta Commons-pool project. All of the major J2EE Appservers and most of the Java Servlet Container Servers support connection pooling. The only exception that I can think of off the top of my head is Sun iPlanet 6.0 or less. Tomcat will support connection pooling and has a decent how-to on their website.

[OT] RE: J2EE vs .Net (was Struts vs .NET???)
Hopefully, this will trigger this to be an OT topic from this point forward. I have been ignoring this thread for the most part, but with all the postings figured I would glance over it. There are dozens of large Struts sites out there. I have worked on a lot of Enterprise Class websites that Use Struts. It is a solid viable framework solution which is easy to learn and implement. A few sites that I have been involved with: BlueCross / BlueShield TRICARE Call Center AHOLD USA MeadWestvaco Rockwell Automation All of these sites I consider large (Some running several hundred thousand transactions per hour and supporting thousands of simultaneous users). I am not knocking .NET or any other programming platform. There are many great examples of each of these available. But Struts is a framework will be around for a long time to come. JSF, SHELL, and others are building off of the lessons learn from this framework and will become just as popular over time. If you don't like Struts, Java, J2EE... fine, go on to .NET or what ever else you choose. The are all valid solutions with limitations and features that attract and deter based on what you need. But can we please get these emails back on track. I would prefer reading messages on tips, techniques, and problems rather than all this complaining. It is amusing to a point, annoying after that.

Re: [OT]java bean question
From the javabean spec this is acceptable. However, it is not good coding standards to have a property in all upper case. The java standard naming convention has constance as all upper case, properties as camel case. Struts would have a problem with this because it is looking for the first letter of the property to be lowercase.
if this is a procedure name it would be better to have the parameter as either p813name or procP813NAME.

In 1.2.7 you simply change the ActionErrors to ActionMessages. you still save the errors with the saveErrors method and it works the same in the tags.

Exception - General Question
Hi everybody,
Up to now, I was handling my exceptions in my Action class as follow :
ActionErrors errors = new ActionErrors();
try{
..
..
} catch (Exception e) {
//Put print stack trace in System.err so it is logged
e.printStackTrace(System.err);
//
errors.add(ActionErrors.GLOBAL_ERROR, new
ActionMessage(errors.keyDescribingError : +e.getMessage()));
saveErrors(request, errors);
// Forward control to the appropriate error page
forward = mapping.findForward(erreur);
}
However ActionErrors is now deprecated so I'm wondering if using
ActionMessages instead is well appropriate.
I have seen that a common use is to define an ExceptionHandlerseems to
be nice as we just handke the errors in one place but :
- It seems that using ExceptionHandler we lost the finest degree of the
exception and we have not a personnalized message for the exception thrown.
Of course, we could do a catch in the Action class and throw the
exception with the personalized messaged but then I have another question :
- Does ExceptionHandler slower than catching the exception in
each Action class?
Finally, What is the best practice to handle exceptions in struts?
Thanks in advance for your help

Re: Architectural question
So long as the Action class is performing a truly generic function then I see no problem with this. Additionally, the name of the Action should reflect the function that is being performed. For example, if the action is forwarding a bean embedded in the form to a web service, the Action should be named something like PostWebServiceAction. However, if the action has logic built into it to determine which jsp is feeding the action and how to Interpret the data, this should be broken out.

Re: Architectural question
I would name the actual action based on the functionallity: action path=/postRequest1 type=org.moon.PostWebServiceAction name=formTest1 forward name=default path=test1.jsp/ /action action path=/postRequest2 type=org.moon.PostWebServiceAction name=formTest2 forward name=default path=test2.jsp/ /action This would indicate that you are running two seperate web pages that both attempt to post data to a web service. The process for posting these requests are identical an therefor redundant to create two independent action classes to handle the business flow. however, based on the action path you are calling you can control the validation and forward differently. The key is that the code within the PostWebServiceAction does not contain any business logic, only deligating calls to other model functions.

Re: Help me with my problem in Automatic Validation please
There are two approaches to correcting this. 1. If you are using Sessions, Place the datalist into the session instead of the request. This will insure the datalist is available, but can does add overhead to the application. Additionally, if you do not clean up the data, this can use up memory unnessicarily. 2. Instead of returning the page to the input page, set the input of the action to action1. This will return the page to the action that builds the input page instead of returning to the imput page directly.
