Changing The Result Page
I am making a mobile site for my current web application. I have a
huge number of actions that return to JSP pages. I have a mobile
detection class written.
Is there a way that I can change the result page if the user is on a
mobile device?
I want to avoid having to write this in all my actions:
if(mobile) {
return SUCCESS_MOBILE
} else {
return SUCCESS
}
If I could change the result page it would make it easier. For
example if it is mobile then I replace the result page of
/mydir/myPage.jsp to /mydir/myPage-m.jsp.
Any suggestions?
Thank you,
Rich

Re: Changing The Result Page
This looks like a good Idea. I will test it and Dave N's suggestion as well.
Thank you All

To extend on this idea, instead of requiring all your actions to add a
getBtype(), you could use an interceptor that determine's the Browser Type
and sets a context attribute you could access using:
result/${#btype}/Profile.jsp/result

You could also add a btype (browser type) macro to your jsp paths like
this...
result/struts2/${btype}/Profile.jsp/result
Your actions would have to have a getBtype() method that supplied that
portion of the path.
This assumes you keep the mobile jsp pages in a separate directory
then the desktop.
Another way is to create a custom result type ( extend
org.apache.struts2.dispatcher.ServletDispatcherResult) have it mung
with your paths and set it to be the default result-type.
(One of the things I love about Struts 2 is number of options you have
to solve a problem).

DOJO Rendering
Due to the deprecation of the DOJO plugin I have been trying to recreate all of my web site GUI without using Struts 2 tags. When I create a Tabbed Pane, the web site loads, then the Tabbed Pane renders in view of the user. Before the UI renders it looks like a mess. When I used the struts 2 tags I did not have this problem. The GUI 99% of the time was rendered before I could see it. Now it seems that I always see the GUI render. I dont want the user to see any GUI until it is rendered properly. Was there something configured in Struts 2 that had the pane rendered before the client saw it? Is it possible to achieve this without the Struts 2 tag library?

Re: Performance issue with large data(such as images)
Thanks, Rich, I''m happy to help. If I use BLOB, I have to make a lot of change to my code. Therefore, I have to persist it as String. I used base64 to encode and decode the byte[] into String. Because I resize the images to small ones. I use a VARCHAR length about 10k~20k to persist the String. Thats fine, if you don't want to do a hugh code change then keep it the same How often do you need to load all 300 images? If it is forum style I would imangine a limited number of posting per page say max 20. So the would be a maximum of 20 images per page load. If this is true, which method is the best among the above three? Which method is 'best' depends on what you want. For fast access and low memory - persist to hard drive If you must use the least amount of memory as possible, persist the images to the hard drive and store the file reference to the url in the database. If I want to persist images to the hard drive of server. Shall I persist the data inside WAR or outside? Because user can change their portrait, does it mean it must be persisted outside WAR? No just make a base dir in your app called 'userAvatar' or something similar. Then persist the image as user_.gif ( = the user id). When they chage their image override the file. Also as stated by Pawel, make sure you have a performance problem before you try to solve a performance problem. -- View this message in context: http://www.nabble.com/Performance-issue-with-large-data%28such-as-images%29-tp23945029p23948048.html Sent from the Struts - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
Re: Performance issue with large data(such as images)
I should have also mentioned that there are security issues with persisting to the hard drive. I would recommend saving to the database and loading the images as needed. Do not save them to session. I do not think you will have a performance problem. Rich - To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
Re: Performance issue with large data(such as images)
You should persist the images as bytes, in a binary field or something similar. 1. Because the image is large, it's not efficient to store it in objects(beans). Well this depends on the Bean. Is the bean stored in session? If yes then it will take up some memory. If you dont have alot of memory I would not recommend this. 2. Because I have many users(say 300), if I store all the maps(userId and image) in the session, the session will be huge. Again if your requirement is low memory usage then dont store large objects in momory for a long time 3. Because I have many users(say 300), if I access the db for each user's image, the worse case is I will have to access db for 300 times. Well this is the trade off Memory vs Resources to Connect to a DB. Even if the images are not stored in session they will still be held in memory when getting them from the DB. How often do you need to load all 300 images? If it is forum style I would imangine a limited number of posting per page say max 20. So the would be a maximum of 20 images per page load. You could also Store the images in the hard drive of the server, and store a URL to the image in the database. This would reduce the memory overhead. Did you try to do any test to see what the impact of retrieveing the data from the database is? If you must use the least amount of memory as possible, persist the images to the hard drive and store the file reference to the url in the database. Or even store the images as userId_avatar.gif. That way you can link the file to a user id and have no need to store the url. Use a base directory for storing the images. Before you guess if something is a performance issue, you should test to see what the actual cost of each method of image storing and retrival is.

I have some global properties in my application that I need to access from several of my JSP pages. In my application I have a base action which all of my actions use. I was thinking of putting a getGlobalProperties method in that action that return an instance of an Singleton that holds my properties. My other thought was to use an interceptor plus a singleton to add the properties to the stack. I'm not sure if this is possible with an interceptor. I am looking for some feedback on these designs.

Re: Struts newbie - Advice on file downloading
Hi,
I have the following defined:
action name=generatePdf class=com.abc.ReportAction
method=generateReport
result name=success type=stream
param name=contentTypeapplication/pdf/param
param name=inputNamefileStream/param
param name=contentDispositionfilename=Report.pdf/param
param name=bufferSize1024/param
/result
My action lookks like this
public String generateReport() {
//use api to build PDF
//the api takes an output stream
//so at the end of my method i have an output stream containg the file...
//bout is my output stream
//file stream is a member of my Action (referenced in the param
name=inputNamefileStream/param param)
//fileStream is an InputStream
fileStream = new ByteArrayInputStream(bout.toByteArray());
return SUCCESS;
}
You will have to parameterize the XML to handle multiple file types:
param name=contentType${mimeType}/param
Which you will set in your action. Same goes for the other parameters.
I'm not sure how to get the browser to display a save dialog, I think
it has to do with the mime type. I think application/octet-stream
will work.

Re: Converter trying to set String on int field
After some debugging the culprit was the checkbox interceptor.
It uses false as a default value when nothing is selected. I tried
setting the uncheckedValue to -1 and it didnt work.
interceptor-ref name=completeDefault
param name=checkbox.uncheckedValue-1/param
/interceptor-ref
I upgraded to the latest version of Struts 2 and then it worked.

Re: Submitting a Date to an Action
I think I am going to write my own. After experimenting with the date
time picker it only seems to convert the date if its in this format
mm/dd/yy. In my application the user can choose their own date format.
When I have a format like 1 May 2009, the datetime picker value does
not get converted. It is expecting to set a String instead of a Date.
I am still trying to get my own converter to work right. If I get
something written I will share it with the group.

Hi Richard,
Have a look at http://struts.apache.org/2.1.6/docs/type-conversion.html
It says that dates - uses the SHORT format for the Locale associated with

Re: Submitting a Date to an Action
My date field is one text box with a Date Picker Widget. The
converter does the valid date validation for me by attempting to parse
the date in the Util class. If it returns null then I know I got a
parse exception.
I am including my convertFromString code below. I need it to handle
both single dates and an array of dates. My form always has a date
range, plus N number of date ranges to select. I wrote it to work for
both. Any criticisms or questions about the code are welcomed.
public Object convertFromString(Map context, String[] values, Class
toClass) throws TypeConversionException {
ArrayListDate dates = new ArrayListDate();
Date returnDates[] = null;
if (toClass == Date.class ||
toClass == Date[].class) {
StrutsRequestWrapper srw = (StrutsRequestWrapper)
context.get(com.opensymphony.xwork2.dispatcher.HttpServletRequest);
User u = (User)
srw.getSession().getAttribute(Constants.USER_SESSION_KEY);
Util util = new Util();
for (int i = 0; i values.length; i++) {
if (values[i].trim().length() 0) { //all date ranges
are submitted even if they are empty
Date tmpDate = util.parseDate(values[i], u.getDateFormat());
dates.add(tmpDate);
if (tmpDate == null) { //parsing failed
throw new TypeConversionException(Could not
parse date [ + values[i] + ] using format [ + u.getDateFormat() +
]);
}
}
}
returnDates = dates.toArray(new Date[0]);
}
if (returnDates.length 1) {
return returnDates;
}
return returnDates[0];

I wrote my own method based on having three select dropdown boxes for the

Rather than do it as a type converter, I did it as an interceptor, with
three getters/setters in the action (getStartTime_Day, getStartTime_Month,
getStartTime_Year). The interceptor uses reflection when it encounters a
Date setter (with a suitable annotation) in the action to look up these
fields and parse them into a Date for setting. Lets me do validation at the
same time.

Reusing GUI and Actions
I have a form in my web application that can be accessd from different
places (Namespaces) in the web app.
It looks something like this
/Admin/EditSchedule.action
/MySchedules/NewSchedule.action
/Create/NewSchedule.action
/Create/EditSchedule.action
The are subtle differences in how the data is handled each time. For
example, in Admin all data can be updated, in Create and MySchedules
the data can be added. Also in Create there is another area where the
data can be edited with the exception of two fields that can not be
changed.
The issue I am having is I need to submit the form to different
actions depending on where the user is. For example in Admin, the
action will do an update on all the data (this takes 3 steps), in
Create it does an add plus it uses some other functionality from the
model (5 Steps).
So far I have used the same action name that saves the data in each
name space. So every Forms action is SaveSchedule.action and each of
the name spaces provide a mapping for this action name. Each action
does different thigs with the data. This has workled so far and has
allowed me to use the exact same JSP for all areas in my web
application. Since I have added the Edit function to the Create
namespace I can not do this anymore. Since they share the same
namespace I can not reuse the SaveSchedule Action name. The save from
the edit on the Create side on has 2 Steps.
Does any one have any suggestions on the best way to handle this? I
figured I can do the following:
1) In my JSP pages, leave out the Action in the form and provide it
in a java script function.
Currently my JSPs look like:
//unique things to that area of the app
include javaScriptFile
include formCode
//more unique things
Change it to
//unique things to that area of the app
script
//common function called from the form code
function saveScheduleForm() { ... }
/script
include javaScriptFile
include formCode
//more unique things
This way each area that uses the form will provide its own
saveScheduleForm method.
I don't like this apprach since it could be very confusing to other programmers.
2) Rather than reuse the form code Cut and Paste it to every area of
the application I need it and change the action of the form to reflect
what action to submitt to.
I don't like this option because I dont want to maintain multiple
copies of this GUI.
3) Hand in some flag about what page I am on and choose logic based on that.
I don't like this because it does not seem like a good practice.
Does anyone have any suggestions?
Thanks,
Rich

Re: Set Unchecked Value in the Checkbox Interceptor
I think I found the problem. All of my check boxes have the same
name. After examining the code in the interceptor:
if (key.startsWith(__checkbox_)) {
String name = key.substring(__checkbox_.length());
iterator.remove();
// is this checkbox checked/submitted?
if (!parameters.containsKey(name)) {
// if not, let's be sure to default the value to false
newParams.put(name, uncheckedValue);
}
}
The name will be in the parameters since they are all the same. So
when it finds one that is unchecked (not submitted), it will not get
added since the name is already there from a check box that has been
submitted. I will have to find another way to achieve this since my
check box list is dynamic and can be any size. I will post some code
when I finish.

Re: AJAX Valiadation in 2.0.x
Here is a solution I came up with so far. I wrote an action to
validate. This calls my validateData() method.
I Used the JSON plug in to return the fieldsErrors collection to dojo.
Here is some javascript:
Please note when looking at this that I have modified the original
template that displays error messages. I also modified the
validation javascript addError to add errors to this box. Hence the
null values. I kept the same method signature in case someone needed
the old functionality. The old template would take the field name so
it could display the error message in the correct spot IIRC.
function testAjaxSave() {
clearErrorMessages(null);

I currently have this working. But I still have a few questions:
First I wrote a method called validate. At this point I found out
that I was overriding the ActionSupport method. When I tried to find
more information on this method I couldn't. When I search for XWork
or Struts 2 validation I always get the XML or Annotated validation.
These validations are too simple for the needs of this particular
form.
Where can I find out more information on how to implement the validate() method?
Will this method work with Ajax validation?
Will this require less work on my part if I do this?
My solution was very easy to implement thanks to the built in
fieldErrors and the JSON plug in. I guess I'm just trying to find the
quickest and easiest way to do this. I don't want to reinvent
anything if Struts can provide it out of the box. By creating the
mechanism for populating the s:fieldError/ did I rewrite somethign
that Struts can do for me?

If you reference the URL you will see 4 distinct elements
!ELEMENT struts (package|include|bean|constant)*
Each element contains their own attribute list e.g.
!ELEMENT result-type (param*)
!ATTLIST result-type

class CDATA #REQUIRED
default (true|false) false
Did you have a question?
IIRC the question was whether or not Ajax validation required the use of XML
validation.
Off the top of my head I don't actually know--since it takes about a minute
to write a validate() method I'd probably just try it and see if it works.

I was wondering if it is nessessary to use the XML for validation with
Ajax? I was hoping to use some validation on the server side action
to do this. Is it possible?

Where can I find out more information on how to implement the validate() method? What do you want to know? The ValidationAware interface API docs list the methods available, most of which are self-explanatory. The validate method comes from com.opensymphony.xwork2.Validateable and is implemented by com.opensymphony.xwork2.ActionSupport. The API description from each is : void validate()Performs validation. void validate() A default implementation that validates nothing. Subclasses should override this method to provide validations. I was wondering if this works with Struts 2? I can't find anything outside of XML and Annotated validation when I search. Will it work with built in Ajax validation? If yes, do I implement the validate method using the ValidationAware API? Will this method work with Ajax validation? I still don't know--if you're already doing Ajax validation, and already have a validate() method, wouldn't you already have found out? I have a validateData method. I didnt use validate because I wasn't aware on how the valdate method is used with Struts. Will this require less work on my part if I do this? Less work than what? Less work than my solution. JSON Plugin + Dojo. It wasn't alot of work to do this I just want to make sure I am not rewriting something that Struts 2 already provides. By creating the mechanism for populating the s:fieldError/ did I rewrite somethign that Struts can do for me? AFAIK the Ajax validation as shipped only deals with field-specific errors, not the entire collection of errors--but I've never tried that, so I'm not really sure. Somebody with more experience doing that may know. I am using the field specific errors, I am just handling them differently. If the shipped version works with the validation javascript provided in the struts.jar then it should work with my code. I kept the same js functions.

OGNL and Java Methods String Arguments
I'm trying to call the String replace method from OGNL. I can't find
any specific examples on how to do this.
I tried the following as a test: [EMAIL PROTECTED]@toString()
This worked ok. My problem is I don't know how to pass string
literals to the method.
Here is my current code:
s:property value=[EMAIL PROTECTED]@toString()/'
Here is what I would like to call:
[EMAIL PROTECTED]@replaceAll(',
Matcher.quoteReplacement(\\'))
(I am replacing a single quite with the JavaScript escape character
for single quote \')
If some one can help me out or point me to some good examples that
would be great.

Multiple Results or How should I handle this?
I have an Action that could display several pages based on some info
passed to it.
Basically, its a preview action that will show the proper preview page
based on some input.
The way I am think of doing it is to use custom results to redirect to
the proper preview page:
if (preview1) {
return CUSTOM_RESULT_PREV1;
} else if(preview2) {
return CUSTOM_RESULT_PREV2;
}
and so on. But I'm not sure if this is the 'best' way.
The page that is calling this, could be accessed from different
modules in the application, and the preview gives alot of information
about the specific module item that loaded this page. Since this page
can be called by X number of modules, and that number of modules will
grow in the future, I am looking for a smooth way to handle the
'preview' button on that page.
To handle the saving of the data, I abstracted the BridgeDAO.
So if the shared module is called ModX then the save action looks like this:
The action gets passed the module that called ModX and the id of the
module item that called it
modxDao.save(modX);
bridgeDao = factory.getBridgeDao(ModuleId);
//so now we have a dao for assiating the modX record to the module
that created it
bridgeDao.associateModX(moduleItemId);
As you can tell, the MOdX data can be associated with other different
modules in my application.
So does any have any suggestion on how I should handle the 'preview'
portion of this?
The preview pages that are currently in the system, are all very
unique with regards to content and layout. So I was thinking a bunch
of ifs with custom results as shown above would be a good way to go.
But I am also wondering if this should be abstracted, or would that be
over kill.
Any comments would be greatly appreciated,
Rich

The reason I am asking this is bacuase when I upload a file over 15MB I get no result mapped for INPUT exception in my error log. When I do map a result for input the app hangs.

Setting disable attribute dynamically
If the disable attribute is present in a HTML tag it will be disable,
no matter what the value of the attribute is.
So if I have a s:select and I say disabled=false it will be
disabled (renders disabled=disabled).
But if we have a text, and we set readonly=false it will not be editable.
On my page my action determines my users access level - fullAccess
(user can edit anything) or partialAccess (user can edit certian
fields but see the other fields)
I have a text field set up like this s:textfield
readonly=%{fullAccess}. which works fine.
But s:select disabled=%{fullAccess} does not work.
I tried this s:select s:if test=!fullAccessdisabled=true/sif
/ But the s:if tag is causing a syntax error.
The only solution I came up with was
s:if test=!fullAccess
s:select disabed=true ...
/s:if
s:else
s:select ...
/s:else
So I have 2 s:selects and s:radios for every radio/select
I would prefer to have it like the textfields so I dont have to have 2
pieces of code for each select and radio.
I figured i could do an if around a script block at the bottom of
the page and disable them with javascript but that might be a little
confusing for future coders who have to work on this.

div id=dataImageDivs:property value='id'/ /
this piece of code is placed in a loop, and creates a small menu for each
images I have in galleries. The dataImageDiv is used to contain whatever
form I need.
The problem is that my s:property tags contained in my s:a tags aren't
interpreted. After few manipulations, I observed that the s:property tag
is interpreted only if it's not contained in a struts tag. For instance :
div id=dataImageDivs:property value='id'/ /
produces
div id=dataImageDiv1 /
BUT
s:div id=dataImageDivs:property value='id'/ /
produces
div id=dataImageDivs:property value='id'/ /
Thus, my piece of code produces :
div id=menu_image_gallerys1
1
s:a theme=ajax href=%{EditImageGallery}
targets=dataImageDivs:property value='id'/Edit/s:a
s:a theme=ajax href=%{MoveImageGallery}
targets=dataImageDivs:property value='id'/Move/s:a
s:a theme=ajax href=%{copyImageGallery}
targets=dataImageDivs:property value='id'/Copy/s:a
/div
div id=dataImageDiv1/
As I'm using this in a loop, it's obviously not working, the targets and the
divs not matching.
This is driving me nuts. Do I do something wrong ? Would you have an idea ?
The s:head theme=ajax/ is well included in my header.

Re: s:select and pre-selection
I have a select that populates with a int,string id/value combo. To get the s:select to select the proper option I had to crate another value in my action (int myId). This would be set to the id of the option to select. Then I had to set the name attribute of my select to myId (name=myId).

Re: Invoking action method from javascript
you can say, document.location.href = 's:url
action=myRemoveAction?myId=' + myId;
This will cause the whole page to refresh, so you should probably have
a prepare method if you have any data that needs to be populated on
that page (ie your table).
I personally would use Ajax to make the call, having a full page
refresh on each click could be annoying to the user.

is it possible? thank you very much

Subject: Re: Struts 2 and SOA
Ok. All of my actions call my DAOs for their logic. Most of my
actions look like this:
public String myActionMethod() {
myDAO.getARecord();
//populate the action with record fields (will be displayed on a
form or table etc)
if (someField = Status.EDIT user.hasFullAccess() ) {
fullAccess = true;
} else {
readOnly = true;
}
}
The most 'busniess logic' that my action contains is setting
variables based on database information (fullAccess or readOnly). Im
not sure if this should be moved out of here and into the DAO or not.
also might have a save() method that determines if I should call add
or update on my DAO.
Are fullAccess or readOnly used in your view? How would you expose them if
you put them in a service layer? If they are used in the view then it seems
to me like they have nothing to do with the service and shouldn't be there.
Maybe an interceptor would be a better idea if this logic is sprinkled
throughout your S2 application.
So, would I expose my DAO as a service? Is this a good Idea? DO I
need to add another layer (POJO) or would that be overkill? If I do
have some security logic in my Action, should this be moved to a POJO
that calls the dao and set up its own members, isReadOnly, hasAccess
etc. I also do some data validation in my action, ie I check to see
if the data passed to my action is allowed to be accessed by that user
(this aviods URL rewrting and re writing POST data with proxy
servers). So I get an id of something the uesr wants to access and I
make sure that user is allowed to access it. Should this be moved out
of the action? Did I make a mistake putting it there? If so I
imagine putting this logic in to a POJO which controlla access to the
DAO, then the action calls the POJO or web service. I guess then the
POJO and DAO become my Model and no busniess logic is in the action at
all. Now that I think about it, this seems like a good idea. I was
new to MVC when I was thrown into Struts 2 so hopefully this misake
does nto ccost me too much time. If I do this, (Action - POJO -
DAO) then I would expose the POJO as the web service?
Thank you for your input,

I recommend checking Amazon for books on SOA or checking out some of the
excellent web sites devoted to it. I googled and came up with this, which
looks pretty good for a start. This is a huge topic in and of itself but it
doesn't really have anything to do with Struts.

Re: Struts 2 and SOA
I am not using Spring yet. We currently just finished migrating our application to struts 2. We have not had a chance to look into Spring yet but it was recommended by the person who started the struts migration. If this is part of the solution to getting our struts app to share it functionality then we would have to do it. We are developing a new System that in the future will have to talk to certain part of our current system and integrate with work flow applications. I also want to develop this new application so it can share its functionality easily. I am wondering how my design will change knowing that I have to do this. Where does Struts fit in? Does it fit in at all? Any comments are greatly appreciated.

Re: [s2] Date format in TextField
I'm not sure if I understand you correctly but... I want to display editable dates in textfields. This should be as simple as using a textfield (input type=text) as your date field I cannot use JavaScript, so datetimepicker isn't an option. So the user will have to manually enter the date by typing. Currently the date is displayed as dd/mm/yy if there is a value. How can I change this to be dd/mm/? We recently has this probem. We gave the user to an option set the date format for our whole system. Now whenver we read dates out of the database they get formatted to the users specified format. If you are using one date, then you can hard code the format (in a properties file) and apply it to all dates that come out of the database. I believe in Oracle, and possibly other DBMS you can also specify a format that you want the date to come out as when it is queried. You wont have to apply any formatting if this is the case. For validation If you can't use java script the best way I can see to do this would be to have your field: MyDate: __ (dd/mm/) This will inform the user of the correct format. You will have to validate this format on the server side and if the format is not dd/mm/ you can return the error and let the user know tha the format is wrong.

Re: Struts 2 and SOA
I dont see any need for .NET interoperability in the future, but it would hurt to have that option. I like your typo more than what you actually meant ;) Ha ha, that is quite funny. Another thing to look at is the RESTful plugin. It allows the same action to serve back data in different formats depending on (well, I'm simplifying) the extension used to call the action. This means your action could return JSON, XML, HTML, heck, CSV, depending on how it was called. This is a lighter-weight approach to SOA that allows for a pretty high degree of flexibility; it can be used to feed AJAX components, Flash apps, plain-old-websites, testing, etc. and can serve as a stepping stone* to more elaborate SOA architectures if it turns out more is necessary. Dave * RESTful Plugin: the Gateway Drug. I can see how this would work, but it almost seems a little dirty. I would prefer to use the J2EE API to implement the SOA. Could I take the parts of my Strtus app that I want to share, and turn them into services that both my strtus app and any other client can call? I am open to the REST plugin, I would just like to make sure I am not creating more work in the furure if I have to integrate these Services with Workflow apps and other systems. I would like to do it the best way possible the first time, even if it means longer development.

Re: Submit, ajax, targets and action
If I understand you correctly, You could write you own submit
function(s) that does its own ajax with dojo
function submitFunctionA() {
var kw = {
url:'s:url action=myAction/',
load:function(type, data, evt) {
//up to you what happens here
},
method: POST,
error: function(type, data, evt){
//error
}
};
dojo.io.bind(kw);
}
}
So you could have each of your submit buttons call their own function
and forget about the form

However, the action attribute does not appear to work with the AJAX theme;

Populate Form from DAO
Struts 2 allows us to automatically populate our forms if we name our
fields correctly, which is wonderful.
My actions usually go something like this
execute () {
MyObject o = myDAO.getRecord(id);
member1 = o.getMember1();
member2 = o.getMember2();
}
MyObject is a JO for hold a row in the database. I like the fact that
I can name my form field 'member1' and it the interceptor will set and
get from my Action. I dont like having to set up each member variable
in the action with the members my class. Is it possible to somehow
have Struts automatically populate an Java Object rather then the
Action? I thought I remember reading about this before but I'm not
sure. It's not a big deal, and I know I can use OGNL to access the
value, but I wanted the convience of mapping a fieldName to my custom
object. Is this possible?
Thank you,

Re: Populate Form from DAO
Yes,
I know I can do it this way. I'm just being lazy.
I want:
s:textfield name=member1/
To automatically get/set MyObject.getMeember1() rather then it
automatically setting it in the Action and then having me create the
Object and populate it with values.

Objet : Populate Form from DAO
Struts 2 allows us to automatically populate our forms if we name our fields
correctly, which is wonderful.
My actions usually go something like this
execute () {
MyObject o = myDAO.getRecord(id);
member1 = o.getMember1();
member2 = o.getMember2();
}
MyObject is a JO for hold a row in the database. I like the fact that I can
name my form field 'member1' and it the interceptor will set and get from my
Action. I dont like having to set up each member variable in the action with
the members my class. Is it possible to somehow have Struts automatically
populate an Java Object rather then the Action? I thought I remember reading
about this before but I'm not sure. It's not a big deal, and I know I can
use OGNL to access the value, but I wanted the convience of mapping a
fieldName to my custom object. Is this possible?
Thank you,
Rich

Re: How to improve dojo performance in Struts 2.0.9
Is the $resources$ directory WEB-INF? On Oct 6, 2007 8:51 AM, Jeromy Evans [EMAIL PROTECTED] wrote: I thought I'd share the instructions I prepared for creating a dojo 0.4.2 custom profile for Struts 2.0.9. The objective is to bundle all the required dojo resources into dojo.js to avoid the numerous slow sequential requests for resources. This makes a massive performance improvement to the default ajax theme. Instructions for improving the performance of dojo 0.4.2 in Struts 2.0.9: $resources$ is assumed to be your web resources directory 1. First, configure struts to serve the static files directly from $resources$/struts instead of from within struts-core-2.0.9.jar: a. extract struts2-core-2.0.9.jar/org/apache/struts2/static/* to $resources$/struts/ b. edit struts.properties and set struts.serve.static=false c. also extract the javascript and css files from struts2-core-2.0.9.jar/templates/* to $resources$/struts/ as this will be helpful later eg. $resources$/struts/ajax/dojoRequire.js Confirm that your application still works before proceeding. It's essential that resources are loaded from the directory rather than the jar. 2. Download the source of dojo 0.4.2. You won't need to modify it. The download location doesn't matter. We assume it's in release-0.4.2/ svn export http://svn.dojotoolkit.org/dojo/tags/release-0.4.2 This is almost identical to the version bundled with struts2.0.9. 3. Use an editor to create a dojo custom profile as the file release-0.4.2/buildscripts/profiles/struts2.profile.js. This file defines which dojo resources you use directly. Essentially it specifies which code will be included in dojo.js. An example that includes almost everything is provided at the end of this email. 4. Copy the struts widgets into the dojo directory so they can be included within dojo.js. That is, copy $resources$/struts/dojo/struts/* to release-0.4.2/struts. This is the directory that contains the widget and widgets subdirectories, css and some images. 5. Build dojo using ant. This will create a new dojo.js file: cd release-0.4.2/buildscripts ant -Dprofile=struts2 -Dstrip_and_compress=true clean release intern-strings strip-resource-comments (You may be asked to run it twice). Pay some attention to the build process. In particular, note whether it finds the struts widgets and 'internalises' the related resources. If not, see Step 4. You'll probably notice a lot of things are included that you don't need. That will be helpful later for optimizations. Some errors will occur while stripping the comments but these are ok. 6. When the build process completes the release directory will contain all the files you need. The content of the release directory can be copied over the top of $resources$/struts/dojo. You'll notice it's almost exactly the same as the original, although dojo.js is probably larger. It's okay to delete the demo, test and release subfolders before copying to your application. The src subfolder must be distributed with your application as it contains images used by dojo. 7. Clear your browser cache and test your application again. You should note the larger dojo.js file being loaded and significantly fewer requests for resources by dojo Hopefully it's also a lot faster. That's it. Now you can go back and optimize the profile by removing resources you don't need. There's examples in the profiles directory. Repeat the build/test process to find the right balance. I also recommend editing $resources$/struts/ajax/dojoRequire.js to remove the reference to the Editor2 if you don't use this as it's a very,very heavy-weight resource. Hope that helps someone else. Improvements comments welcome.

Re: DisplayTag - show image by condition
You have to make your own decorator:
I assume your table is populated with a 'Member' list or something
similar. In your table decorator create a method that returns the
image based on the condition:
public class MemberListDecorator extends TableDecorator {
public String getType() {
String returnString = new String();
Member data= (Member)getCurrentRowObject();
if(data.isVip()) {
returnString = img src=\vip.gif\/;
} else {
returnString = ;
}
return returnString;
}
}
DOnt forget to include the decorator in your table tag:
display:table cellpadding=1 cellspacing=1
name=memberDAO.members decorator=myPackage.MemberListDecorator
.
.

Re: Can struts2 tag embeded inside javascript
I don't see any javascript in your post but if you are creating an
imput element this should work as long as the javascript is on your
jsp page in script tags:
text = document.createElement(input');
text.setAttribute('type','text');
text.setAttribute('value','s:property .../');
The key is to use single quotes. Although I have never used the
struts tags to set values in dynamically created text inputs, I have
used them in javascript like this:
document.location.href='s:url action=editUser/';
It should work the same for you.
If you show me some code I may beable to help you better.

Struts 2 Session Timeout
I noticed while developing my application that Struts 2 (I think) will recreate your session when it times out. I have several name spaces used in my packages such as: 1. /Admin 2. /Design 3. / While I am hitting actions in the /Admin or /Design area of my application, if the session times out I am redirected back to my main page with a restored session. If any of the link point to / then the session does not get restored. How can I restore the session in the / name space? Is there any reason why this is not happening for the / name space?

Submit all Checkboxes

My form has x number of 'Name' text fields x number of 'Activate' check boxes for another. The user will fill in the 'name' and check the box to 'activate' the user. I was using two arrays in my action to store the values of the check box and the text.

In addition to configuring log4j to use a FileAppender to write logs to

String stackTrace = (String)
pageContext.getAttribute(stackTrace);
new ExceptionLogger().logException(stackTrace);

where ExceptionLogger is a class you write to log the stackStrace or

I use a similar fragment in the JSP to email a copy of the stacktrace to
the administrator if the exception page is ever displayed.

Re: Exception Handling and Logging

A requirement has come up where the client does not want the user seeing any stack traces etc. So I want to log the exception in the action and then redirect to a generic error page. I have the exception results and the exception mapping set up. I was wondering what is the best way to log this. Right now I have my Exception result directing to an action which calls my log class. The problem is a can not seem to get the exceptionStack passed into this action so I can not log all of the information. Any ideas?

This is looks neat until you look at the situation when an error occurs. In order to ensure that the s:select is correctly filled the error result has to send the browser back to Action A, which is being done as a redirect. The problem with this is that all actionMessages and actionErrors get lost during the redirect, and thus the user can't see what was wrong. To get around this I use the store interceptor, but this causes problems if validation is turned on (it will bounce the user to the error result of Action A if an errorMessage is present - see https://issues.apache.org/struts/browse/WW-1963 for the bug report). So I end up with the validation interceptor turned off and having to hand code some validation, and the store interceptor turned on for several actions.

Sanitize Text
I was wondering what the best approach would be for taking form data passed to an Action and removing 'special characters' from the data. I am having issues with users pasting text from word docs etc. We only support ISO-8859-1 as of now and there are some characters that Word will replace such as ' and with character that are outside the 8839-1 character set. I was thinking about an interceptor that would sanitize the request parameters before they are passed to the action. Is this a good approach? Can anyone suggest a better one?

Re: Custom user roles and Action
I wrote a LoadApplication action that executes after my user has logged in. It checks the database to see what roes they have and it fills the session with a few variables such as admin = true; designer = false; etc. by default they are all false. Then I wrote an interceptor that checked their access from the session. If they have access the Action they are requesting would execute. If they did not have access I would redirect them to the main page. You could also have the interceptor check the Database directly. I am not a security expert, but this should be more secure than storing those values in session. There will be more overhead in checking the database before every action.

Re: Custom user roles and Action
An interceptor is exactly like a filter. I runs before and after an
action executes.
Check out the following:
http://struts.apache.org/2.x/docs/interceptors.html
http://struts.apache.org/2.x/docs/writing-interceptors.html
Also the 'FAQ section at the bottom of the first like has some useful
information.
Here is my intercrept method from the SystemAdmin check:
public String intercept(ActionInvocation actionInvocation) throws Exception {
//get my user object form the session
Map session = ActionContext.getContext().getSession();
User user = (User)session.get(Constants.USER_SESSION_KEY);
boolean allowAccess = (null != user) (user.getSystemAdmin());
if(allowAccess) {
return actionInvocation.invoke();
} else {
return BaseAction.NO_ACCESS;
}
}
Next I had to add the interceptor to my SysAdmin package:
interceptors
interceptor name=accessChecker
class=rs.app.SystemAdminAccessInterceptor/
interceptor-stack name=sysAdminDefault
interceptor-ref name=accessChecker/
interceptor-ref name=defaultStack/
/interceptor-stack
/interceptors
and change the default stack:
default-interceptor-ref name=sysAdminDefault/
Now every action in that package will call my access checker before it
executes. If the check fails then the NO_ACCESS constant is returned
(which is a constant in my BaseAction class whcih equals noAccess).
Now that I think about it, Im not sure if I should have put that
constant in that class..anyway...
I defined a global result to handle the noAccess result:
global-results
result name=noAccess type=redirect-action
param name=actionNameHome/param
param name=namespace//param
/result
/global-results
This result returns the user to the Home screen. In my case the user
should never see the link that takes them to restricted parts of the
page. I wrote this in case a curious user started typing in URL's. I
don't give them an error I just kick them back to the main page.

Re: Defining a validate() method
addFieldError(fieldName,message); will add a specific field
error. If you are using the XHTML theme, the error will appear above
the field.
This should set and clear the validation message for you. If you are

Re: Defining a validate() method
I forgot to add that you can also use annotations or XML validation
for simple validations. If you set the validate=true on your s:form
and you are using the XML validators, it will generate the client side
javascript nessessary to do the validations. After the form submits
it will do those validation again on the server side and if you have
any additional validation to do that is not covered by a validator you
can add the validation cod to your action.
I have tried to write my own validator recently but I got stuck and
because of a time constraint I did my validations in my action with
addFieldError. I would like to see more information on writing
validators and how a include the javascript to generate for that
validator

Hi
which version of commons validator are you using?

i so, you can see:
integer - validates that a field can be converted to an Integer.
field property=ordernumber depends=integer
arg0 key=order.number/
/field
intRange - validates that an integer field is within a specified range.
Requires min and max variables to specify the range. This validator depends
on the integer validator which must also be in the field's depends attribute.
field property=age depends=required,integer,intRange
arg0 key=employee.age/
arg1 name=intRange key=${var:min} resource=false/
arg2 name=intRange key=${var:max} resource=false/
varvar-namemin/var-namevar-value18/var-value/var
varvar-namemax/var-namevar-value65/var-value/var
/field
integer checks if the field value can be converted into an integer, i didn't
check the code but i supose something like that:
Integer.parseInt(...)
maybe you are using intRange instead

Re: How to format the actionerrors and actionmessages in the jsp page?
Hi,
I had the same problem. I did not like the way the error were being
displayed (In a new row above the field that has the error) To do
this I have to chenge the XHTML template
First I removed the validation from the controlheader-core
#--
REMOVED
We have our own Error area
#if hasFieldErrors
#list fieldErrors[parameters.name] as error
tr errorFor=${parameters.id}
#if parameters.labelposition?default() == 'top'
td align=left valign=top colspan=2#rt/
#else
td align=center valign=top colspan=2#rt/
/#if
span class=errorMessage${error?html}/span#t/
/td#lt/
/tr
/#list
/#if
--
I added this to the form.ftl
#include /${parameters.templateDir}/xhtml/validationarea.ftl /
In that file I wrote the following code: It output all of the error
into a single div. 'Holder Div' is used so the client side
validations will work too.
#assign hasErrors = fieldErrors?exists/
div id=holderDiv
#if hasErrors
#if (fieldErrors?size 0)
div class=errorMessage id=errorDiv name=errorDiv
#assign keys = fieldErrors?keys
#list keys as key
#list fieldErrors[key] as errorMessage
${errorMessage?html} br/
/#list
/#list
/div
br/
/#if
/#if
/div
Next I had to change the validation.js file to use my div to display the errors:
function addError(e, errorText) {
try {
var errorDiv;
var error = document.createTextNode(errorText);
var br = document.createElement(br);
//Create the errorDiv it it does not already exist
if(!document.getElementById(errorDiv)) {
errorDiv = document.createElement(div);
errorDiv.setAttribute(id, errorDiv);
errorDiv.setAttribute(class, errorMessage);
errorDiv.setAttribute(className, errorMessage); //ie
hack cause ie does not support setAttribute
} else {
errorDiv = document.getElementById(errorDiv);
}
errorDiv.appendChild(error);
errorDiv.appendChild(br);
//Make sure all error moessage are display before showing the div
if(!document.getElementById(errorDiv)) {
document.getElementById(holderDiv).appendChild(errorDiv);
}
} catch (e) {
alert(e);
}
}
function clearErrorMessages(form) {
var errorDiv;
var errorDivChildren;
if(document.getElementById(errorDiv)) {
errorDiv = document.getElementById(errorDiv);
document.getElementById(holderDiv).removeChild(errorDiv);
}
}
I commented out all of the logic in clearErrorLabels() since it does
not apply to what I am doing.
I think thats about everything. There might be one or 2 places you
have to change some code in the template. The big thing here is you
have to change the XHTML template. I'm not sure if the simple
template has error handling, it might be easier to change.

Hi,all:
I would like to add header and footer to the actionerrors so as to it can
display in the way my client like.
In Struts1.2,i can just put the following code in the properties file:
errors.header=table class=warningtrtd
errors.prefix=li
errors.suffix=/li
errors.footer=/td/tr/table
and it could work as I excepted.
Now i am trying to use struts2,but it can NOT work in the same way.
Any help?
btw,I have put the code in the globalMessages.properties and put the file in
the classpath,as well as defined the struts.xml as:
constant name=struts.custom.i18n.resources value=globalMessages /
Thanks for reading and looking forward to any reply.

Re: [S2] Multiple Submits with different actions in a Form
I'm not sure if this is what your are looking for, it is doing the
control logic on the client side. Instead of using s:submit to submit
the form you could make 3 input buttons:
input type=button onClick=doAction1()/
input type=button onClick=doAction2()/
input type=button onClick=doAction3()/
and the write the following javascript:
function doAction1() {
document.getElementById(formId).action = 's:url action=myAction1'/;
document.getElementById(formId).submit();
}
function doAction2() {
document.getElementById(formId).action = 's:url action=myAction2'/;
document.getElementById(formId).submit();
}
function doAction3() {
document.getElementById(formId).action = 's:url action=myAction3'/;
document.getElementById(formId).submit();
}
then in your struts.xml:
action name=myAction1 class=MyAction method=method1
.
.
.
/action
action name=myAction2 class=MyAction method=method2
.
.
.
/action
action name=myAction3 class=MyAction method=method3
.
.
.
/action
You don't have to use the Ajax theme on your form, you can write the
Javascript using the DOJO library your self. All the nessary files
are included when you use the s:head tag

I'm still in the process of learning S2 and I was curious on what's the best
practice in implementing a form with multiple submit buttons
I've read that there are multiple way to implement this.
One way is here:
http://struts.apache.org/2.0.8/docs/multiple-submit-buttons.html
Although I was thinking I had to redo my setup of my action class and have
all the actions point to one method - execute() and from there i would check
a parameter to determine what my next step would be:
public String execute() {
if (method.equals(searchMethod)) {
doSearch();
return SUCCESS;
}
if (method.equals(addMethod)) {
doAdd();
return SUCCESS;
}
}
something to that effect.
But I also wanted to try having an action class with different methods and
in my struts.xml the different actions would point to the different methods
of my action class.
My problem though is I have a form with multiple submit buttons. I tried
specifying the action on each submit button but the action in my form
overrides the action specified in the buttons. I tried removing the action
parameter in my form but it would take the current action and still override
the actions specified in the buttons. How do I have a form with multiple
submit buttons with different actions? What would be the best practice in
implementing this? Would implementation be any different if my submit
buttons are ajax themed?
Thanks

Tree Tag
I am using the tre tag to display a tree of items. I got a very basic tree showing. Is it possible to have the tree node do something when you click it? I tried onclick but it didnt seem to render that attribute into the HTML. Is it possible to add some extra html to each node (for example a check box)?

Change the Tabbed Panel look
How do you change the look of the tabbed panel? I assume you have to override some css or something similar but I can not find any information on it. Thank you - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Setting application properties
You could read the global properties from a file or DB when the application first loads into an object of your choice (A Map for Key,Value) . Then put this object in session. On 7/19/07, SimonK [EMAIL PROTECTED] wrote: Thanx for you reply. The 'problem' with this solution is that I then have to explicitly access the file each time I want a property. I was hoping that There was a place that I could load such parameters then simply access it. The things I have experimented with (and which have failed) are: attempt 1 - place the line: constant name=gov.brs.mapping.RegionSelector.tmpDirectory value=/temp / in struts.xml (just after struts). attempt 2 - place the line: gov.brs.mapping.RegionSelector.tmpDirectory=/temp in struts.properties, which is in WEB-INF/classes In both cases, the class gov.brs.mapping.RegionSelector has static getter and setters for tmpDirectory, which is a static member. I was hoping that this would set tmpDirectory (a String) in gov.brs.mapping.RegionSelector. This does not happen. The above solutions would not be ideal in any case. What I would really like to know how to get struts to put key value pairs in the application map (which I *think* is the appropriate place) or atleast on the stack, when the application is loaded by tomcat, so I can write something like: String tempDir = ActionContext.getApplication().get(tempDirectory); or String tempDir = ActionContext.getValueStack().get(tempDirectory); to get at it. Can I do this... and if so, how?

Re: Loading Screen!!
Look at the walking tour of the mail reader application. http://planetstruts.org/struts2-mailreader/Welcome.do It uses a loading page to redirect to an action. The loading page is just a plain html page the has a META HTTP-EQUIV=Refresh CONTENT=2;URL=My.action tag. I made a similar page with Loading... and I used an animated loading gif for the background. This will display until the next jsp page is fully loaded.

Another way is to display partial page as it loads.eg 20 rows at a time.And keeps on loading untill the whole result is recieved. What would be the better way.
