Re: About StrutsTypeConverter
I am confused that why the signature of convertFromString is public Object convertFromString(Map context, String[] values, Class toClass) instead of public Object convertFromString(Map context, String value, Class toClass). What's the point to pass a String array instead of a String argument into this method?

OGNL exceptions are swallowed by struts2
Hi, Is there anyway to get better error message there's an error occurring in ognl? Everytime there's an exception in ognl it's swallowed. And I ran into some No Result Found for XxxAction error. It's extremely hard to debug, because there's no any useful information in it. All of them seem to be converter related problem. Is there anyway to make struts 2 easier to debug? There's an article complaining about this issue: http://raibledesigns.com/rd/entry/does_struts_2_suck Thanks, Vincent
Re: Error Throwing With Struts 2 Tags
It's really an annoying issue of struts2. It took me long time to troubleshoot this kind of problem. One time I came across NoClassDefFoundError. It was swallowed by xwork. I wouldn't know it if I'd not used eclipse debbuger to step in the code. I wonder why this simple issue is not fixed in struts2/xwork. Struts2 is a great web framework if it easier to trouble shoot.

[s2]Runtime exception in a bean setter
I'm using struts 2.0.9. I have a bean in a action. The setter of the bean will throw a RuntimeException when the value is not a legal value. But when I submitted the form with the illegal value, and the RuntimeException was thrown. Nothing happens to struts 2 container. The exception disappeared and is not displayed in log. What I expected is a Error 500 page, but it seems nothing happen at all except the value is not set to the bean. The behavior is quite different from struts 1. Is this a feature of struts 2? Hide the exception of setter of bean? Or can I turn this off in struts.properties or struts.xml? Thanks! Vincent Lin

[S2] Preselected option in s:select/ tag
Hi!
I am using struts 2.0.6 and I encountered a problem in s:select/ tag
today.
In my JSP:
s:select name=adminGroupMapData.adminGroupRid
headerKey= headerValue=--
list=adminGroupList listKey=adminGroupRid
listValue=adminGroupRid/
In my Action, I have a method:
public ListAdminGroupEbo getAdminGroupList() {
return this.adminGroupList;
}
The data bean of the list has a get method:
public Integer getAdminGroupRid() {
return this.adminGroupRid;
}
But in my web page the value of the drop-down list generate by s:select/
sometimes can't jump to the value
of adminGroupRid in the data bean (adminGroupMapData.adminGroupRid).
I found a rule of thumb that when the value of
adminGroupMapData.adminGroupRid is less than 1000, it works.
But when the value is greater than 1000, it doesn't work.
Why? Is there any way to solve this problem?
Thanks,

Re: [S2] Chinese encoding problem

Re: [S2] Chinese encoding problem
Chris,
Thank you.
I solved this problem finally.
I use a CharacterEncodingFilter you mentioned to set character encoding to
UTF-8.
Actually I've tried this filter before, but it didn't work.
The reason why it didn't work is the order of fitler mapping is incorrect in
my web.xml.
This filter must be in front of struts 2 filter like this:
filter-mapping
filter-nameSetCharacterEncoding/filter-name
url-pattern/*/url-pattern
/filter-mapping
filter-mapping
filter-namestruts2/filter-name
url-pattern/*/url-pattern
/filter-mapping
But it sitll strange that I've traced the struts 2.0.6 source code and found
that id does change the encoding of HttpServletRequest in
Dispatcher.java(line 650):
public void prepare(HttpServletRequest request, HttpServletResponse
response) {
String encoding = null;
if (defaultEncoding != null) {
encoding = defaultEncoding;
}
Locale locale = null;
if (defaultLocale != null) {
locale = LocalizedTextUtil.localeFromString(defaultLocale,
request.getLocale());
}
if (encoding != null) {
try {
request.setCharacterEncoding(encoding);
} catch (Exception e) {
LOG.error(Error setting character encoding to ' + encoding
+ ' - ignoring., e);
}
}
if (locale != null) {
response.setLocale(locale);
}
if (paramsWorkaroundEnabled) {
request.getParameter(foo); // simply read any parameter
(existing or not) to prime the request
}
}
And there is a setDefaultEncoding() method in line 227:
@Inject(value=StrutsConstants.STRUTS_LOCALE, required=false)
public static void setDefaultLocale(String val) {
defaultLocale = val;
}
It seems to get encoding parameter from struts.propertes with key
struts.i18n.encoding in struts.properties file.
But somehow it doesn't work in my app.
The filter has solved this problem. But I think in struts 2, we shouldn't do
this filter?
It makes the code a bit ugly.
The behaviors in IE and Firefox are different really confuses me.
Why the browser affect the character encoding in HttpServletRequest?

Vincent Lin wrote:

:(
You mentioned that MSIE seems to fail, while Mozilla Firefox works. Is
this behavior consistent? Does ff always work? Does MSIE always fail?
Can you check to see what character encoding (in the HTTP headers) is
being sent from the client when things work? What about the failure
situation?
It's possible that MSIE is not sending the correct request encoding (or,
more likely,not sending it at all). If you know your clients will (or
should) be sending UTF-8 all the time, you could use the
CharacterEncodingFilter mentioned on this list several times to simply
override the default encoding used when the browser sends no encoding
(or override it unconditionally). This might work.

[S2] onsubmit in s:form tag
Hi! I wrote s:form action=Admin_create onsubmit=return (validateFields()) in my JSP, but struts 2 rendered the following html: form id=Admin_create name=Admin_create onsubmit=return (validateFields()); return true; ... Why it renders onsubmit=return (validateFields()); return true; instead of onsubmit=return (validateFields()) ? Can I make renders onsubmit=return (validateFields()) only? Thanks!
[S2] How do I create a client side validator?
Is there any document talking about how to create a client side validator in struts2? Thanks!
Re: [S2] onsubmit in s:form tag
I usually use onsubmit in form tag to do javascript validation. For example, onsubmit=return (validateFields()) is specified in html form tag. If the javascript function validateFields() return true, the form will submit, otherwise it won't. It works fine in struts 1. But struts2 always add 'return true' in onsubmit event. That causes validateFields() useless. On 6/26/07, yitzle [EMAIL PROTECTED] wrote: Um... Firstly, it does the same thing. I think if you move the code to the submit button it renders it as expected.

Thanks for your help. But I only see how to configure client side validators. What I want is to create a customized client side validator.

Re: [S2] onsubmit in s:form tag
If you try it in a plain html form, you will know the difference. That's really useful to use onsubmit=return (validateFields()) in form tag, and validate all fields in validateFields() function (If you are not using validators.). Return true in validateFields() if all validations are passed. Return false when there is something wrong in your input.

Hi Dave, Thank you. You are right. There is an error in my validateFields() function. It works now. The return true in onsubmit has nothing to do with my problem.

[S2] datetimepicker reset value to 00:00 when type=time after submitting page
I have a datetimepicker in my JSP to let user select time:
s:datetimepicker name=searchBean.createTimeTmTo
language=en_US type=time displayFormat=HH:mm /
When user select 10:15 and submit to webserver, after the web page refreshes
the value becomes 00:00.
Is this another datetimepicker bug?
I have a type converter for converting time the format string is HH:mm:
public class TimeConverter extends StrutsTypeConverter {
private static Logger log = Logger.getLogger(TimeConverter.class);
public Object convertFromString(Map context, String[] values,
Class toClass) {
log.debug(entering convertFromString() values[0]=' + values[0] +
');
if (StringUtil.isEmpty(values[0])) {
return null;
}
try {
Date dt = TimeUtil.getGuiTimeFormat().parse(values[0]);
Object rtn = new java.sql.Time(dt.getTime());
log.debug(rtn= + rtn);
return rtn;
} catch (Exception e) {
log.error(e, e);
}
return null;
}
public String convertToString(Map context, Object o) {
log.debug(entering convertToString() o= + o);
String str = null;
if ( o != null ) {
str = TimeUtil.getGuiTimeFormat().format(o);
log.debug(entering convertToString() str= + str);
}
return str;
}
}
But the debug log shows the time str is 10:15.
Thanks!

list=#{'true':'true', 'false':'false'} /
But the default radio button is not checked in my page.
(While autoActivate is true the radio button of 'true' should be checked,
but it isn't.)
It works when I map s:select/ to java 1.5 enum, but it doesn't work when I
map s:radio to java.lang.Boolean.
Did I do anything wrong?

[Shale] Old form values still there after Cancel button.
Hi all, For the life of me I can't get JSF to stinkn forget values that were entered on a form. The view controller is request scope. If I start to enter data in a form and then click the Cancel button, which has immediate=true, the values entered by the user reappear in the form when I return to the page. The action of the Cancel button returns home which maps to a navigational rule to the home page that is a redirect. I've tried these two things which haven't worked: 1) traverse the ViewRoot looking for UIInputs and setting the submitted value to null. 2) set the value binding to the VC managed bean to null. I had read that JSF will reuse evaluated expressions if they aren't null. Any help is greatly appreciated.

Shale startup - without Spring.

Shale: onclick=disabled='true'; not calling Action Method. (stopping double click)
Hi all, My project spec is asking me to disable form buttons once they are clicked. It seemed easy to me, just add onclick=disabled='true' to the commandButton. But as anything I've found with JSF, it isn't that easy. When I do this, the action method isn't being called after it passes validation. If I remove the onclick attribute, the form works fine; so I know it isn't a logic failure in the ViewController. I noticed that JSF inserts some of its own onclick logic to the button too.

Best Practice - Correct usage???
Hello all, I have an application to edit some data stored in the database. I have 2 situations. 1. When a user clicks New or Edit Mouse, the user is brought to a form that either displays an empty form or one that is pre-populated. This is done with the following mapping: pre action path = /mouseAction type = org.jax.mgi.mtb.jaxpathwi.actions.MouseDispatchAction name = MouseSubmitForm scope = request validate = true parameter = dispatch input = mouse.jsp forward name=setupSuccess path=/WEB-INF/jsp/mouse.jsp/ forward name=insertSuccess path=/WEB-INF/jsp/mouse.jsp/ forward name=updateSuccess path=/WEB-INF/jsp/mouse.jsp/ /action /pre This works fine, but upon successful insert why couldn't I just forward it back to the setupSuccess portion? Like the following: pre action path = /mouseAction type = org.jax.mgi.mtb.jaxpathwi.actions.MouseDispatchAction name = MouseSubmitForm scope = request validate = true parameter = dispatch input = mouse.jsp forward name=setupSuccess path=/WEB-INF/jsp/mouse.jsp/ forward name=insertSuccess path=/mouseAction.do/ forward name=updateSuccess path=/WEB-INF/jsp/mouse.jsp/ /action /pre Do I have to do something different in my Action class? It is running in an infinite loop and eventually running out of memory. 2. When a user updates a mouse, I want them to be directed to a summary screen of the mouse which has the following mapping: pre action path = /mouseSummary type = org.jax.mgi.mtb.jaxpathwi.actions.MouseSummaryAction scope=request forward name=success path=/WEB-INF/jsp/mouseSummary.jsp/ /action /pre would I change my action mapping to the following pre action path = /mouseAction type = org.jax.mgi.mtb.jaxpathwi.actions.MouseDispatchAction name = MouseSubmitForm scope = request validate = true parameter = dispatch input = mouse.jsp forward name=setupSuccess path=/WEB-INF/jsp/mouse.jsp/ forward name=insertSuccess path=/mouseAction.do/ forward name=updateSuccess path=/mouseSummary.do/ /action /pre But how does one pass in the variables that mouse summary needs to know like the id of the mouse? Am I making any sense to anyone? Thanks! Matt - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Can't figure out how to do if then else with Struts logic tags
Not sure if this is a solution for you or not, but you could also put
your JSPs under WEB-INF
directory so that they cannot be directly accessed by a user. They
would instead have to go
through an Action first.
Filters may be your best bet (and yes, that is the URL to look at).
As far as JST syntax, you could use something like:
c:choose
c:when test=${numberOfResults==0}
!-- DO SOMETHING --
/c:when
c:otherwise
!-- DO SOMETHING ELSE --
/c:otherwise
/c:choose
Hope that helps!

Dave,
I totally agree with you about doing this kind of checking in an action
class and I AM doing it there. However, the problem is that I still need a
way to prevent a user from going to the jsp w/o first logging in.
Let's say the user logged in during a previous session and bookmarked the
jsp. They can get back to it w/o having to login. I know that once they
submit the form the action class will catch that they're not logged in and
send them back to login page. But I'd rather catch it before then. I hate
to have the user fill in a bunch of information, submit form and THEN get
redirected to login.
I'll look into JSTL. Are you saying it has if-then-else type of
processing? Could you point me in the right direction for that and for the
check if object exists in session issue?
Also, I haven't used filters before. We just upgraded from Struts 1.0.2 so
I'm pretty ignorant of all the features of newest version of Struts. Is
this some kind of Struts filter or what is described here?

is null because a user could have tried to go directly to an internal
(after login page) page using a bookmark. How can I check for the
presence
of an object in the session?
Again, if you're doing this outside of a JSP (highly recommended) it's
trivial. Otherwise you could always use a JSTL tag to check for a value
in the appropriate session scope attribute key.

Strecks?
I saw this on TSS today: http://www.theserverside.com/news/thread.tss?thread_id=39840 Strecks, a set of open source extensions to the Struts framework aimed at Java 5 users, has been released. Strecks (which stands for Struts Extensions) is built on the existing Struts 1.2.x code base. Basically Struts + a whole lot of @annotation candy?

Display Struts Configuration
Hello all, Last week I saw a blog which showed how to display information at the beginning of your JSP about Struts such as which action the request was mapped to, the form being used, and associated information like the request headers. I should have bookmarked it, but I didn't. I have checked my history, googled for it, etc., but cannot find it again. Does anyone know what I am talking about and/or can they post a link for this information? Or does anyone have something similar? Thanks for your help.

Re: [OT] Filter Help!
Hello everyone,
If this is not the right place to post this could you please let me know
where. I have searched the forums and Google and cannot find an answer.
I have a Servlet filter that checks to see the content length of the
request.
long contentLength = request.getContentLength();
If contentLength is greater than some configurable size, I would like to
stop the request and send back a response saying that the request is to
large.
This is being used for a file upload Everything is working, except it
seems like the ENTIRE request (or file) is sent BEFORE my redirect is
happening.
My logs are showing the correct information at the appropriate times,
but the entire request is being processed before I can send a request back.
Is there a way to immediately cut off the request and return a
response? Is there a better way to do this?
Request Size Filter: REQUEST LENGTH=401458785
Request Size Filter: CONTENT TYPE=multipart/form-data;

Re: Struts EJB 3 tutorial
Actually, it's been my understanding that struts is pretty much a BYOM (Bring Your Own Model) kind of framework.

Re: [Shale] Property in ViewController Backing Bean is null
I think you may running into a simular problem that I ran into. I have the following scenario: page 1 has the user choose from a list of options. On page 2, the form saves the selected option of page 1 in a hidden field in its form. In addition the selected value from page 1 is used to populate a pull down on page 2. So the user hits the submit button on page 2 to save the changes and KA-BLAMMO, I get a NPE. What was happening was the JSF was attempting to Validate the pulldown values in the Validation phase. This was before any of the hidden fields were set. So because the hidden fields weren't set, the retrieve of the pulldown was failing. I saw 1 of 2 solutions: 1) Turn off the validation of the pulldown. Because, hey... why would I need to validate a pulldown? - it isn't like a user can mistype something. OR 2) somehow get the hidden fields to be set before any retrieval of the pulldown is made. The JSF mailing list from Sun gave no help for turning off the validator for the pulldown. So I had to do the following, for which I give myself a big Capital H for HACK. In the contructor of the backing bean, I grabbed the request parameters myself and called the setters from there for the values that were needed to get through the validation of the pulldown. Perhaps someone here can help turn off the need to retrieve the pulldown values in the validation phase. I hope this will help your situation, as well.

Shale: postRender method?
Hi All, I was wondering if there is an easy way to get a postRender method to be called in my Shale ViewController. Is a new Phase Listener the only / best option? Perhaps I can extend a Shale class to also call a postRender method? Here is my scenario: I have the concept of an ErrorEventCollector in the ViewController. Basically, the collector is passed around in the model calls to capture errors during the model execution. This might include errors caused by validation checks on the retrieved data from the DB, as well as any exceptions. These events can be generated in any phase - init, validation, application, or render. In my BaseViewController - I want to have the event collector checked for any events. If there are events in the collector, then I want to create FacesMessages for each event. I tried putting the check in the Shale destroy method, but the messages weren't being displayed by the JSP. So It seems I need to have this check as the last step in the render_response phase. Thanks for any help.

Re: Shale: postRender method?
Hmm... I guess a phase listener wouldn't work for me. From what you say, it appears that the outcome of the phase is already determined before the afterPhase listener is triggered. Is there a another place for me to plug into the steps taken during a phase, that is, before the final steps in the phase are completed? Or at least, I just need the FacesMessages to not get processed until the last step of the render phase.

Re: Shale: postRender method?
ok... I got it to show the messages... I did what you suggested and moved the h:messages to the end of my page - THANKS! But the method to convert my ErrorEvents into FacesMessages still needed to be called. So I made it return true and set it as the render attribute for the messages tag. AHHH! It worked, but ew. :) I could change my design so that the FacesMessages are created immediately when the events are added to the collecor. That would eliminate the need for the render attribute. BUT, I'll need to beg for forgiveness from my UI designers when I tell them that the h:messages tag MUST be at the end of the page. I guess the original intent of the FacesMessages was to be used during the Validation phase. Hmmm. Is it a sign of mis-use of the JSF framework if my getter methods in the render phase can produce FacesMessages? HMMM Perhaps I could override/extend the responseComplete method to do my custom stuff first, and then call super.responseComplete??? Is this a good approach or even possible or even the right method to override? It seems like a path to the dark side. Thanks for the help.

I put the messages tag in there, but I'm getting nothing from that tag.
I've witnessed JSF swallowing exceptions before. Is there a way to get
JSF to log the stacktraces to my logger?
I've really simplified my test case and I'm still seeing the problem.
I have a pull down at the top with a submit btn.
When the submit button is clicked, it called the actionListener as
expected. The page is rerendered with the second part of the page
showing the item selected with another button. When the 2nd button is
clicked, no actionListener is called.
Here is the sample code:
public class PulldownTest {
private static final Log LOGGER =
LogFactory.getLog(PulldownTest.class);
private String selectedFilterValue;
public SelectItem[] getFilterPulldown() {
SelectItem[] items = new SelectItem[3];
items[0] = new SelectItem(,);
items[1] = new SelectItem(1,1);
items[2] = new SelectItem(2,2);
return items;
}
public String getSelectedFilterValue() {
return selectedFilterValue;
}
public void setSelectedFilterValue(String selectedFilterValue) {
this.selectedFilterValue = selectedFilterValue;
}
public boolean isItemSelected() {
boolean isItemSelected = null != selectedFilterValue
!.equals(selectedFilterValue);
LOGGER.debug(isItemSelected=+isItemSelected);
return isItemSelected;
}
public void handleSelectItem(ActionEvent event) {
LOGGER.debug(handleSelectItem());

Hi all,
For some reason a cmd btn of mine isn't calling its actionListener
method when it is clicked.
Here is the situation. I have a pull down at the top of my page
which chooses the item that I want to edit below. I hit the submit
button next to the pulldown, and the second half of the page is
rendered. I used the rendered attribute on the table containing the
rest of the form.
So when I change a few items in the second half, I hit an update
submit button to save the changes and POOF... nothing - the page
just refreshes. the actionListener is never called. Infact no
action or action listener
Re: [Shale] a command btn within a conditionally rendered form not getting actionListener.
I have discovered something:
Instead of using the rendered attribute on the table, I put a c:if
around it and it called the actionEvent as expected. What the heck!
I'd prefer not to mix JSTL with JSF, so I'd like to hear what is going
on here.
It seems to me, if I was able to click the button, it should call the
event. Why does it need to check the rendered flag again? That is,
it should process the input data for the state in which it was
rendered, before using data dealing with how it is viewed.
Here are the logs generated from clicking the second button:
PulldownTestVC - isItemSelected=false
PulldownTestVC - isItemSelected=false
PulldownTestVC - setSelectedFilterValue()2
PulldownTestVC - isItemSelected=true
PulldownTestVC - isItemSelected=true
PulldownTestVC - isItemSelected=true
PulldownTestVC - isItemSelected=true
PulldownTestVC - isItemSelected=true
PulldownTestVC - isItemSelected=true
PulldownTestVC - isItemSelected=true
PulldownTestVC - isItemSelected=true
my guess is that one of the first two calls is the check for the commandButton.
I haven't gotten to the PhaseListener yet, but I'll give it a shot.
Just out of curiousity, is there a particular reason you want to use an
actionListener instead of an action? The latter is generally easier to deal
with.
I choose actionListener because I read that the actions was ment for
navigational events. In my case, I'm just updating data on the same
screen. It seemed like the right choice, for the time being. What I
didn't really get is why not also have the action methods take a
ActionEvent parameter. It seems like a useful parameter - as different
buttons could, in theory (not that I'd do it), call the same listener,
and then you can switch on which event was received - not unlike the
execute method of Struts-Action.
Cheers,
Jason

The action listener also receives an ActionEvent, but you're correct that it
cannot feed an outcome directly into the navigation system. You can,
however, fake it by doing something like this:
NavigationHandler nh = context.getApplication().getNavigationHandler();
String outcome = ...; // Some outcome string to pretend occurred
String action = #{...}; // Some action to pretend was called (this
would
// normally be the expression for the
action attribute
nh.handleNavigation(context, action, outcome);
context.renderResponse();
Could the rendered attribute be throwing something off?
If the button is not rendered (rendered=false) then it won't be able to
fire any actions, but that doesn't appear to be the case in your sample
code.

One way would be to create a simple phase listener class that listens to all
phases, and logs the before and after events:
public class DebugPhaseListener implements PhaseListener {
public static final Log LOGGER =
LogFactory.getLog(DebugPhaseListener.class);
public PhaseId getPhaseId() {
return PhaseId.ANY_PHASE;
}
public void beforePhase(PhaseEvent event) {
LOGGER.debug(beforePhase( + event.getPhaseId() + ));
}
public void afterPhase(PhaseEvent event) {
LOGGER.debug(afterPhase( + event.getPhaseId() + ));
}
}
Register this in a faces-config.xml file like this:
lifecycle
phase-listenercom.mycompany.mypackage.DebugPhaseListener
/phase-listener
/lifecycle
The clue you are looking for is if Invoke Application is reached. That's
where actions are invoked (assuming immediate is not set). If that phase is
being skipped, it'll likely be:
* A validation error
* An exception during update model values
* Some other code that called FacesContext.renderResponse()
to proceed directly to the rendering phase
Craig
The scopes of all my objects are request, and the Faces Context is
stored on the Server.
Thanks a bunch,

[Shale] a command btn within a conditionally rendered form not getting actionListener.
Hi all, For some reason a cmd btn of mine isn't calling its actionListener method when it is clicked. Here is the situation. I have a pull down at the top of my page which chooses the item that I want to edit below. I hit the submit button next to the pulldown, and the second half of the page is rendered. I used the rendered attribute on the table containing the rest of the form. So when I change a few items in the second half, I hit an update submit button to save the changes and POOF... nothing - the page just refreshes. the actionListener is never called. Infact no action or action listener. Why isn't the action listener called? I've also tried having two forms on the page, where the second form had a hidden field of the selected item of the first form. This would help the situation where the user changes the selected item in the filter form, but also has made changes to the previously viewed item. I'd want to make sure the changes goto the right item. When I tried this, for some reason the getter methods to retrieve the items data was called before the set method for the hidden field was called which gave me NPE's since the item to get the data from hadn't been loaded yet - which is what the set method of the hidden field would have done. Is there a way to control the ordering of which UI objects are processed first? I tried the immediate attribute of the hidden field to get that to go first, but it did nothing. BTW, for the 2 form scenario, when I got the NPE's I would hit the back button to go back to the form, it is then that I would notice that it would call my update Information eventListener method. arg. What is going on here? Thanks, Jason - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: [shale] subview not talking to a backing bean

Re: [shale] subview not talking to a backing bean

Shale: not calling prerender or preprocess, and Navigation issue
Hey there, I've got some unexpected navigation stuff going on, that I was hoping someone can help explain. Here is my use-case: 1) Home page is requested. 2) user isn't logged in, so redirect to login url. 3) after login, navigate to home. In my logs, I'm seeing this behavior, which is wierd... This is just the initial request to the home page, I didn't hit the login button, just yet. HomeVC.init(), requestURI=/cpt/home.jsf HomeVC.prerender(), requestURI=/cpt/home.jsf BaseViewController - /cpt/home.jsf is a secure url and not logged in, redirecting to login: /login/login.jsf HomeVC.destroy(), requestURI=/cpt/home.jsf HomeVC.init(), requestURI=/cpt/home.jsf HomeVC.prerender(), requestURI=/cpt/home.jsf BaseViewController - /cpt/home.jsf is a secure url and not logged in, redirecting to login: /login/login.jsf HomeVC.destroy(), requestURI=/cpt/home.jsf The init,prerender,destroy are not called for LoginVC - Why not? The wierd part is that the browser behavior is working as expected - up to a point. Once I hit the login button, the user is logged in, but the navigation rule in faces-config, isn't sending the browser to the home url. Another interesting thing... after the login form is displayed, and I Manually enter the login URL - the init,prerender, and destroy methods are not called by ANY ViewController. PS... I do have no-cache meta tags in the jsps, and I also set the headers in my baseViewControler.prerender method - so at least the browser shouldn't be caching anything. Can anyone explain what is going on? Any help is appreciated. Thanks, Jason - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Shale redirect to login page for secured pages
Hi there,
I'd like to setup this usecase, in Shale/JSF...
1) user requests a url that is configured as secured.
2) system checks for logged in user.
3) if the user is not logged in, then redirect to the login page.
4) on successfull login, redirect to orginally requested URL.
currently I just have a index.jsp that forwards to home.jsf. In my
faces-config, I have
!--home navigation rule--
navigation-rule
from-view-id*/from-view-id
navigation-case
from-action#{login.checkAuthenticated}/from-action

/navigation-case
/navigation-rule
the checkAuthenticated method isn't even being called when the home.jsf page
is called.
anybody know what I'm missing?

Does anybody know why the following JSP code does not work:

monitorBean contains rows, and each row contains columns

The JSP code should build a table from this bean, displaying
one String in each cell, with a hyperlink of the type

Using struts forms as Value Objects: your opinion?
Hi, I'm currently designing and developping an enterprise J2EE application based on Struts. In this application there's a layer of Data Access Object which abstract the underlying persistent storage. For populating my struts' *Form I've imagined first a transfert between forms and DAO based on Value Object, associated with helper classes for translating from one type to another. And I realized that struts Form can be in some situations quite good transfert objects, and by doing so we economize development of both helper classes and VO classes. What do you thing about using forms as VO? Do you think it's a dirty solution? Forms are often mirrors of the database's table. Thank you for your opinion.

Can't get html:errors/ working
Hello, I'm trying to get working html:errors/ tag but I fail in this task... The webapp has the following files: - LoginAction.java (extend Action) - LoginForm.java (extend ActionForm) - Login.jsp Here an extract of the struts-config.xml: form-beans form-bean name=loginForm type=app.LoginForm / /form-beans action-mappings action path=/login type=app.LoginAction name=loginForm scope=session validate=false forward name=Success path=/jsp/Main.jsp / forward name=Failure path=/jsp/Login.jsp / /action /action-mappings First the flow branches on the login.do action, which forward to Login.jsp (through 'Failure' forward). The form appears. After validation we fall in LoginAction.execute(), this method does a validate() on the form transmitted (a LoginForm). If validate() returns a not empty list of ActionError encapsulated in an ActionMessages, we save these errors with this.saveErrors(request, errors) (errors is the return of validate()), and we forward to Login.jsp, through 'Failure' forward. In Login.jsp, there's a html:errors/ tag, but even if 'errors' is not empty, this tag does nothing, however errors is really not empty because I can get its content with little java code in the JSP. I don't understand what is wrong. It's like html:errors/ was ignored. Container is Tomcat 5.5.9, struts is 1.2.7. Thanks in advance for help.

the following is from validation.xml:

For me it's still a little early to pop the champagne but I just passed through a major milestone on our Struts app here at work. Struts performed perfectly in the demo.

Struts app to be passed a parameter (of some kind)
Need one Struts app, but must have multiple URLs. Thus http://www.jv.com/company1 http://www.jv.com/company2 actually start the same Struts app, say http://www.jv.com/myApp but must pass something into the Struts app so that it knows who, or rather, which URL invoked it. Thoughts: Write a servlet, handles multiple URLs, init-param set to a unique value for each servlet. Add a header into the http response object before issuing the redirect. Redirect to the Struts app. Where in a Struts app can I pick up the header (or other)? The Struts app, in web.xml, has a welcome file of logon.jsp. Could I get the header here? Doesn't seem to work.

Re: Struts app to be passed a parameter (of some kind)
App Server is WebLogic 8.1. I can try SunOne Application Server also. On Tomcat, do you configure the app xml files? Or is it configured at the server level? In other words, do I need to check the app server doc or the weblogic*.xml or sun-*.xml files doc for the Struts app?

ActionForm.validate() Help
Hello all,
I just downloaded the latest stable build of Struts 1.2. What is a
best practice approach of handling validation in the ActionForm's
validate method since ActionError was deprecated?
Also, how should one display the messages in the JSP? Currently I use:
logic:messagesPresent message=true
html:messages id=message message=true
${message}br
/html:messages
/logic:messagesPresent
Howver this does not display anything when I use the following code in
my ActionForm because errors is obviously not populated with any data:
public ActionErrors validate(ActionMapping mapping,
HttpServletRequest request) {
ActionErrors errors = new ActionErrors();
if (/*some error occurs*/){
ActionMessages messages = new ActionMessages();
ActionMessage message = new
ActionMessage(errors.valueRequired);
messages.add(ActionMessages.GLOBAL_MESSAGE, message);
request.setAttribute(warnings, messages);
}
return errors;
}
However in an Action the following code will work correctly and display
in the HTML rendered by the JSP code from above:
ActionMessages messages = new ActionMessages();
ActionMessage message = new ActionMessage(errors.notfound);
messages.add(ActionMessages.GLOBAL_MESSAGE, message);
saveMessages(request, messages);
Do I have to check for the existence of both messages and errors in the JSP?
Thanks!

Re: [OT] DAO ... where to draw the line?
LAST bump. I promise!
Thanks!
Hi all,
Thanks for the info. Here's another issue.
What if I have an employee search screen that wants to show only some
of the information of an employee (not all). What do you do then?
1. Instanatiate an Employee object and only fill in the relative
information? Keep in mind that this could be just employee name and
location on the search results screen and then when the user chooses
which employee to view I need to get all of the employee information.
2. Instantiate an Employee object and fill out all the information
even though you won't be needing most of it on the search results
screen?
3. Create 2 DTOs, one called Employee and one called EmployeeSearch
DTO. The EmployeeSearch DTO only stores what needs to be shown on
the search results screen and the EmployeeDTO holds all the
information for what needs to be shown on the detail screen?
4. Something else... Another pattern, etc?
Thanks!

Let me explain.
Say you have class named ORDER ad ORDER_DETAILS. (consists-of
relationship) Order without order details is nothing. So you may get
the OrderDetails object as well when you get Order.
Now say you have EMPLOYEE and DEPARTMENT. (has-a relationship)
EMPLOYEE *may* still exists with or without department. So you may
get only id of department and later fetch the department.
Think in employee table, you have relationship (reports-to). If you

Subject: [OT] DAO ... where to draw the line?
[OFF TOPIC]
I know this is a struts forum, but as struts developers using DAOs,
where do your DAO implementation draw the line?
For example:
Let''s say I have three tables:
Employee (contains employee_id, employee_name, and dept_id)
Department (contains dept_id, dept_name, loc_id)
Location (contains loc_id, location_name)
How deep do your classes go to replicate the data?
Do you do this...
public class Employee {
private int id;
private String name;
private int deptId; // just the id
// .. implementation details
}
or do you do this
public class Employee {
private int id;
private String name;
private Department dept; // all of the data
// .. implementation details
}
and so on and so on. Class Department has the same type of
problem. Does it hold just the id for location or a variable class
Location?
Should DAOs just fill in the id (keys) so it is up to the
application using the DAOs to get the Employee class, then the
Department class, and the the Location class like:
Employee emp = EmployeDAO.getEmployee(1);
Department dept = DepartmentDAO.getDepartment(emp.getDeptId());
Location loc = LocationDAO.getLocation(dept.getLocId());
System.out.println(emp.getEmpName() + works in +
loc.getLocationName());
or
Employee emp = EmployeDAO.getEmployee(1);
System.out.println(emp.getEmpName() + works in +
emp.getDept().getLoc().getLocationName());
Now this is just a simple example, but where do you draw the line?
It's possible to go on and on and on and cycle back to employee...
Any thoughts, links, tips, best practices, whatvere would be helpful!
Thanks!

private int id;
private String name;
private int deptId; // just the id
// .. implementation details
}
or do you do this
public class Employee {
private int id;
private String name;
private Department dept; // all of the data
// .. implementation details
}
and so on and so on. Class Department has the same type of problem.
Does it hold just the id for location or a variable class Location?
Should DAOs just fill in the id (keys) so it is up to the application
using the DAOs to get the Employee class, then the Department class, and
the the Location class like:
Employee emp = EmployeDAO.getEmployee(1);
Department dept = DepartmentDAO.getDepartment(emp.getDeptId());
Location loc = LocationDAO.getLocation(dept.getLocId());
System.out.println(emp.getEmpName() + works in + loc.getLocationName());
or
Employee emp = EmployeDAO.getEmployee(1);
System.out.println(emp.getEmpName() + works in +
emp.getDept().getLoc().getLocationName());
Now this is just a simple example, but where do you draw the line? It's
possible to go on and on and on and cycle back to employee...
Any thoughts, links, tips, best practices, whatvere would be helpful!
Thanks!
Matt

Should every Action have an associated form?
Hey everyone! I hope to not get flamed, but it's getting late here and I'm tired of looking through the archives. Should every Action have an associated ActionForm? Is it a bad idea to read a parameter directly from the request in the Action? I have a page where I need to show details for a particular item in our database. People will be directed to this page via a url http://127.0.0.1/foo/bar.do?id=123. If I need an ActonForm, what's the best way to set this up in the struts-config.xml? Thoughts? Thanks in advance!

Struts/Tiles/Taglib/JBoss325 Deployment Error
Hi, I'm using Jboss-3.2.5 and jakarta-struts-1.1 with J2SDK 1.4.2, WinXP I encounter the following exception : java.lang.NullPointerException at org.apache.jasper.runtime.TagHandlerPool.get(TagHandlerPool.java:153) .. java.lang.NullPointerException at org.apache.jasper.runtime.TagHandlerPool.release(TagHandlerPool.java:191) I suspect it is something related to tomcat-5.x because my application was running fine with Jboss-3.2.3 (tomcat-4.x) Could someone give me some hint on : what is the cause of this prob? how to resolve this problem? Please let me know whether there is any other information that I need to provide. Hope that someone could help me. Thank you.
