Tile controller class
I am using a tile controller class to render the tile on the page. Say
if my main action rendering the page is called myAction.do and when I
send the request like https://.../myWeb/myAction.do, myAction.do
will do something and then forward to the page containing the tile.(then
the tile controller comes to the picture). My tile controller have the
following method:
public class MyTileController implements Controller {
public void execute(ComponentContext arg0, HttpServletRequest
request,
HttpServletResponse arg2, ServletContext arg3)
throws Exception {
// how to the the path myAction.do??
// process business logic
}
}
My question is that how to get the path info like myAction.do in the
above method? Thanks.

Struts validator framework
Say if I have two text fields, one label is Please enter name:, and the other label is Please enter SSN:. In struts validator framework, if I need to validate these two fields using required validator, is there any way to relate the field label to the message? Or does struts validator support displaying the validation message right next to the field (so that the user easily know which fields are invalid)?

You can do it by having 3 different methods such as

validateMethod1() validateMethod2() validateMethod3()
then in your form
s:submit key=button.method1 method=method1/
s:submit key=button.method2 method=method2/
s:submit key=button.method3 method=method3/
or you can do by using action aliases and have three validation xml

Can I use one action for displaying and submission (with struts validation)
I was noticing an issue if I use one action for both displaying and submission purposes: Say MyAction.java is for displaying page and also for submission. If on the page there is text field needing the struts validator validation, then if failing validation, I forward to MyAction.java and comes to the validation again, and fail again and forward to the MyAction again. This is an infinite loop, any suggestions to overcome this and still use one action? Or we have to use two actions(one display and one for submission) the serve the purposes.

Then 2 days ago, they have to change the names for all the stored procedure, to makes things meaningful, I have to rename all my java classes. -- this is really a pain.

Then we I create tiles template, I can't put all these css in the template, instead I thought I can do the following: My template: html xmlns=http://www.w3.org/1999/xhtml; xml:lang=en lang=en-us head meta http-equiv=Content-Type content=text/html; charset=iso-8859-1 / titletiles:getAsString name=title ignore=true//title style type=text/css media=screen tiles:getAsString name=myCss1 ignore=true/ tiles:getAsString name=myCss2 ignore=true/ tiles:getAsString name=myCss3 ignore=true/ tiles:getAsString name=myCss4 ignore=true/ tiles:getAsString name=myCss5 ignore=true/ tiles:getAsString name=myCss6 ignore=true/ tiles:getAsString name=myCss7 ignore=true/ tiles:getAsString name=myCss8 ignore=true/ tiles:getAsString name=myCss9 ignore=true/ tiles:getAsString name=myCss10 ignore=true/ /style /head body tiles:insert attribute=header/br / tiles:insert attribute=bodyContent/br / tiles:insert attribute=footer/br / /body /html Then I need to define myCss1 and etc in the tiles-def.xml, I don't know what is the good one to define this, I don't want to define them like the following : definition name=default path=/jsp/common/main.jsp put name=header value=/jsp/common/header.jsp / put name=footer value=/jsp/common/footer.jsp / /definition definition name=mySepeficPage extends=default put name=title value=SMERF gt; Change Request Queue / put name=myCss1 value=the path to the Css1 put name=bodyContent value=/jsp/mySpefic.jsp / /definition Since that will make my tiles-def.xml too massy.

On page 1 I have some text fields such as Name, SSN for example, and the user types in Name and SSN and then submit the form and the navigation goes to page 2. On page 2 I have the bread crumb trail saying Page 1 Page 2. Notice that Page 1 is a clickable link, and when you click on the link, Page 1 is shown. (Page 2, on the bread crumb trail, is not clickable since the current page is Page 2) My question is: (1) in current J2EE/Struts industry standard, does it make sense to display the data that the user entered on Page 1 for Name and SSN when coming from the bread crumb trail on Page 2? (2) what technique I need to use to see the data that the user typed in for Name and SSN on Page 1, when coming from the bread crumb trail on Page 2? My application is a Struts and J2EE based application. Thanks. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Any thoughts? -Original Message- From: Ray Clough [mailto:[EMAIL PROTECTED] Sent: Thursday, May 10, 2007 1:41 PM To: Struts Users Mailing List Subject: Re: The design of bread crumb trail Are you using S1 or S2? I once implemented a S1 bread-crumbs facility using a custom RequestProcessor to put a stack of page url's into the user's session. This worked well, and allowed a page to return to any of the last 3 pages. I used it to go from the catalog page, where the user made a purchase selection, to a page showing details of the order item, and then back to the catalog page. Since the catalog page could be any of a number of pages, returning to the correct one required some special work. The lack of this feature is why on most e-purchase sites they have a link continue shopping, which does NOT take you back to where you were. I've been wanting to implement a Struts-2 BreadCrumbsInterceptor, or maybe a Filter, but have not gotten around to it. I'd be interested if anyone has done this. - Ray Clough Zhang, Larry (L.) wrote: Say I have two Jsp pages, Page 1, Page 2.

Xml utilities
I am trying to develop some classes used for XML parsing or generating purposes. But I think it is difficult to abstract to write a common utility since each XML document is different, and to parse that document, we should have a different parser. So the question is what utility class will look like so that it abstract some common methods/usage so that all the team members can use the utility class.

Hi,
I usually access my cached droplist data directly from the jsp - eg have
placed a bean called ReferenceDataCache on application scope with
getter methods. In jsp I can simply call:
c:set var=schoolList value=${ReferenceDataCache.schoolsList} /
html-el:select ...
html-el:optionsCollection name=schoolList label=description
value=schoolCode /
/html-el:select
I also try to keep my struts forms only containing properties for the
http posted data.
The controllers responsibility is dealing with http requests (flow
control, forwarding to the correct action etc) so I'm not quite sure
what you mean by saying the jsp tag actually by pass the
controller to get the data from Datasource
Additionally, specialized data can be added as request attributes,
either via your action/helper class or some sort of page controller
(tiles has this feature) - the idea behind a page controller (view tier)
is your page knows what data it needs, and your jsps are not tied to
your actions - in an ideal world you could reuse your jsps without
having to change much (or if any) backend java code.
Sometimes action classes/methods contain far to much business logic
which including supplying data necessary for the view - even if you
decide to forward to a different page your action is still preparing
data for a page that no longer needs it!
Just my 2c

The form will be available in the request or session (depending on where

${formName.employeeList} is the list from a JSTL perspective. From

While these classes are critical to the MVC architecture of Struts (as they implement the view portion), they are usually simply a collection of bean properties and a validate method (also sometimes a reset method.) With the Struts 1.1 release, developers have a new set of options to create their view objects, based around DynaBeans. DynaBeans are dynamically configured Java Beans, which means that they take their properties from some variety of external configuration (usually XML) rather than by explicit methods defined in the class. Thus they give improved performance over ActionForm.It doesnot means that you should always use Dynaform .When Static view is required use ActioForm and when Dynamic view is use DynaForm. regards Nishant Patil Software Engineer Cybage Software Pvt.

public calss Object2{
private name;
private id;
private depetId;
private country;
private jobFamily;
private isActive;

Then I create
Object1 obj1= new Object1(); and set all attributes (name, id, depetId)
of this object.
Object2 obj2 = new Object2(); and then set the first three

My question is that is obj1 and obj2 of the same size or usage of

RE: My IsValidToken() cannot trap duplicated submission.
In my application, there will be no validation error in the FINAL submission stage;
the validation error would be called earlier. If however there are other types of
error (like database error, we just stop processing, but the second submission will be
identified. Your question is valid, however, one of the synchronizer token usages is
to prevent the duplicate submission. If you put the resetToken to the last and you
have a long logic before resetToken, here is what will happen (1) you did a first
submission (2) then submit again, at this point, the resetToken is not invoked yet,
(since there is a long logic before it), the action just thinks this is the same token
and it just allows it -which did actually prevent the duplicate submission, right?
Thanks.

RE: Struts security/validation
Oracle sql insert needs to escape apostrophes so that you can insert apostrophes. So
in your case you may need a utility method to convert all your text containing
apostrophes to some thing like ''.
Example: If your user enters I like he's idea, when inserting to data base you need
to convert it to be l like he''s idea.
Hope this helps.

I had a similar problem, which I discovered when one of my users tried to
enter a street address containing an apostrophe. Since I use apostrophes to
delineate my text strings in my SQL statements, this caused a database
error. I fixed it by not allowing apostrophes to be entered into any of the
test fields.
I admit this is overly restrictive, but I don't know how to get the
apostrophe into my database otherwise. How would you do it Craig?
For SQL destined test, I disallow \ and '.
For XML destined text, I disallow , , , \, and .

Hello all,
I'm in the process of trying to secure my struts application against
Cross site scripting, SQL injection style attacks.
One of the things I'm doing to prevent this is trying to restrict special
characters (;.(){}...etc) getting beyond the validator.
Just thinking out loud for a moment ...
Cross site scripting attacks don't happen when sensitive characters
are inside an *input* field. The problem comes if you *output* the
data without filtering for them. That's why the Struts bean:write
tag, for example, filters , , , and ; for you unless you
explicitly tell it not to, so if you are diligent about how you copy
your database data to output pages, you can safely accept these kinds
of character in input.
I notice that Kishore Senji (one of the other respondents in this
thread) is using Google's Gmail, just as I am at the moment. Since
this is a web application, it's a good thing that Googe isn't
disallowing the magic characters on input into a textarea, or else we
would not be able to participate in this conversation :-).
Is filtering input really the appropriate strategy for dealing with
this problem? If successful it will certainly help, but the approach
strikes me as overly restrictive for most application needs.

RE: [OT] Session facade

That would be my first suggestion, but there is considerable cost in something like that, so it's not right for everyone or every situation. So, you can do some more minor things within your aop that should give you decent results: (1) Don't do anything within any action unless a valid session is found. This will keep quite a few people out of your app on it's own since they won't be able to just hack together a URL with a query string. I accomplish this in one app I did by having an ActionHelpers class, and the first thing any of my Actions do is call a validateSession() static method. If no session is present, forward right then and there to the logon page. You must be careful also that there is one and only one place in your code that creates a session, your logon Action most likely. (2) Make sure your running through SSL. Takes care of packet sniffing, more or less. (3) Encrypt the passwords in your database with a one-way hash encryption. Makes administration a little bit of a pain (no way to read the password), but it also makes hacking the system a little tougher. (4) Have good policies with regard to session timeouts and password structure. A 5-minute timeout might be too short depeneding on the app, but it's good security-wise. Make sure you have solid rules for what a password must look like (i.e., 6-10 characters in length, at least one non-alphabetic character and one non-alphanumeric character, must be chaged once a month, etc.). These are all easy to implement, and will lead to a fairly secure system. Not perfect, but reasonably secure. Depending on your environment, it might be plenty. Frank From: Zhang, Larry (L.)

People Soft Component Interface
Sorry for this off topic question, but I don't know which group I should post this question. I posted this on People Soft company discussion group, but no one answered my question. EJB in Java as a technology has become more and more widely used to perform transaction (update, delete, insert) against database. When using Java to perform a People Soft 8 transaction, we need to communicate to People Soft 8 tables via Component Interface(a People Soft 8 Java term). My question is that does using Component Interface prevent we employee EJB? Do you or you know of some one using EJB to perform People Soft 8 transaction via Component Interface? Thanks folks.

Our web application uses Web sphere application server. The main transaction is to update People Soft database tables. We are using component interface (a People Soft term) to update the underline tables in People Soft. Associated to a transaction ( a People Soft database update for example), there will be another Oracle table insert. (The Oracle and People Soft databases are in different Unix boxes). Sounds like a good candidate to use 2 phase commit, and also a good candidate for EJB. I want to gather some pros and cons as whether or not we should use EJB in this case.

It sounds like very promising to me. The only consideration is that caching those objects may cause another issue of usage of the memory.

In your case, this will still help. Lets say you have 20 users all working on the site, they all hit their Show employement Tree page, and you hit the UserDAO.getEmploymentTreeForUserID(int userID) method for all 20 people with different ID's. That will perform 20 separate queries, cache the result, and return it. Now when all those users hit the refresh button on their web page, it hits your DAO again, the same method, with all 20 separate ID's again. But this time, all 20 of them are successful cache hits and are returned immediately. Now say users 1-5 log out and come back 2 hours later and check your employement tree page, IF their list had been stored in their sessions, that would require you to hit the DB again to reload the lists, but because your caching the results in your DAO itself, all of those 5 users that came back and check their employement tree, are getting all their results from the DAO's cache again since it was stored at the application level (the cache is still valid). The other sexy thing is that if someone calls UserDAO.removeUserByID(4) or something liek that, your DAO knows to either (a) aggressively invalid all the cache and have all caches rebuilt, OR (b) you could take some time to intelligently remove that user from all cached values if it was import to you to keep your caches full. It just gives you more options since all your cache building/invalidating occurs in the same DAO class, instead of needing to worry about synchronizing multiple resources and classes with eachother.

However, our business requirement is that in case there is an error, we display the error on an error jsp, then it is not advisable or easily to use html:errors/ since this tag is normally placed on the current jsp page. My questions are (1) is there any way to do in struts to display the error on an error jsp? (2)What is your opinion on pros and cons of these two approaches: Display the error on the current page and display the error on a separate error page? Please answer questions in order if possible.

RE: How to access a variable message resource bundle from JSP
Suppose you have % String countryCode = en; % I think bean:message key=yourPropertyKey bundle=%=countryCode% will do your work. Another way is that you save your Locale object to session in jsp something like session.setAttribute(Globals.LOCALE_KEY, yourLocaleObject); then Struts can just find out the correct resource for different locale when you use the following in the jsp bean:message key=yourPropertyKey Hope this helps. Larry Zhang -Original Message- From: None None [mailto:[EMAIL PROTECTED] Sent: Friday, May 14, 2004 11:40 AM To: [EMAIL PROTECTED] Subject: How to access a variable message resource bundle from JSP Hi again everyone... yesterday, with assistance from some of you folks, I was able to get multiple message resource bundles working to return a Locale-specific error message from one of my Action classes. Very cool. Now I'm trying to do the same thing in a JSP. Here's my question... in my JSP's, when using bean:message, I know that I can specify bundle=en or bundle=de and that works, since I have a properties file set up for English and German. But how can I set the bundle attribute to a variable value? In other words, at present I have String in session called countryCode, and it's literally the value EN, DE, or whatever else. So, is there a way I can plug that string into the bean:message tag's bundle attribute? Or, is there another method of specifying which of a number of message resource bundle to look in for a specific key that can be varied programmatically? Or further still, is there specifically a special method to get locale-specific string in a JSP tag, as I am now able to do in my Action classes?

RE: Sharing what I've learned: locale switching
Additionally, if you want other key(other than org.apache.struts.action.LOCALE
=Globals.LOCALE_KEY) to store your locale,
you can do this:
session.setAttribute(myNewMeaningfulKey,myLocaleObject), then in your JSP you would
use this:
bean:message key=myPropertyKey locale=myNewMeaningfulKey /. This is the way the
locale attribute in message tag is used in struts.
Thanks.

Subject: RE: Sharing what I've learned: locale switching
Thanks for sharing the information. Basically struts using the following
method to decide which Locale is in the session, then load the
corresponding resource bundle:
protected Locale getLocale(HttpServletRequest request)
{
HttpSession session = request.getSession();
Locale locale =
(Locale)session.getAttribute(org.apache.struts.action.LOCALE);
if(locale == null)
locale = defaultLocale;
return locale;
}
So to switch the Locale dynamically, update the Locale object saved in
the session.
Thanks,
Yuanbo

Subject: Sharing what I've learned: locale switching
Because this might be helpful to others, and because I probably would
have
spent another couple of hours figuring it out on my own without the help
of
some people on this lsit, I wanted to give back as much as I could. So,
here's a consolidated bit of info I've learned about switching language
in
your Struts apps...
What I have is a file manager application, more or less just for me to
learn
Struts. I wanted to have the ability to switch languages on-the-fly.
To do
this, I've done the following:
(1) I created two files and placed them in WEB-INF/classes. They are
ofmResources_en.properties and ofmResources_de.properties (en for
English,
de for German). These files contain various text strings in both
language.
For instance, there is a lable on the screen for file uploads which is
defined as follows:
labels.uploadFile=Upload a file:
and for the German version:
labels.uploadFile=hochladen Sie eine Datei:
(2) I added the following entry to web.xml, as an init parameter of the
ActionServlet:
init-param
param-nameapplication/param-name
param-valueofmResources/param-value
/init-param
As near as I can tell, NO entries are required in struts-config.xml.
You
also do NOT need to do anything for each version of the resource file.
As
long as they are named x_ll.properties, where x is the value of
the
application parameter above, and ll is a valid country code, that's all
there is to it.
(3) Next, I added some flag graphics to my web pages, one an American
flag,
one a German flag. Here is the HTML for them:
form name=changeLocaleForm method=post
action=changeLocale.ofm
style=display:inline;
input type=hidden name=languageCode
table width=100% border=0 cellpadding=0
cellspacing=0trtd align=right
input type=image src=img/flag_usa.gif hspace=6
border=0
onClick=changeLocaleForm.languageCode.value='en';
input type=image src=img/flag_germany.gif hspace=6
border=0 onClick=changeLocaleForm.languageCode.value='de';
/td/tr?table
/form
Pretty trivial stuff there.
(4) Next, I created an ActionForm called ChangeLocaleActionForm as
follows:
package com.mycompany.ofm.actionforms;
import org.apache.struts.action.*;
public class ChangeLocaleActionForm extends ActionForm {
private String languageCode = null;
public ChangeLocaleActionForm() {
languageCode = null;
}
public void setLanguageCode(String inLanguageCode) {
languageCode = inLanguageCode;
}
public String getLsnguageCode() {
return languageCode;
}
}
(5) Next, I created an accompanying Action:
package com.mycompany.ofm.actions;
import java.util.*;
import javax.servlet.http.*;
import com.omnytex.ofm.actionforms.*;
import org.apache.struts.*;
import org.apache.struts.action.*;
public class ChangeLocaleAction extends Action {
public ActionForward execute(ActionMapping mapping, ActionForm
form,
HttpServletRequest request, HttpServletResponse response) throws
Exception {
ChangeLocaleActionForm claf = (ChangeLocaleActionForm)form;
String languageCode = claf.getLsnguageCode();
request.getSession().setAttribute(Globals.LOCALE_KEY,
new
Locale(languageCode));
return mapping.findForward(showPathContents);
}
}
As it turns out as someone here informed me, there is automagically a
Locale in session, created based on what is sent by the browser. So, by
default on my system the value en_US is stored in session under the name
Struts internationalization using bean:mesage.../
This sounds easy, but I couldn't figure out how? Suppose I have two resource files for two locales: OnlineResource.properties (for default locale) OnlineResource_it.properties (for locale Italian) In my jsp, I can use bean:message key=myKey/ to retrieve the default locale value for myKey, then how to retrieve the property for Italian locale. The struts doc says we can use bean:mesage key=myKey locale=???, the thing is what should I pass to locale parameter? Thanks.

RE: struts.jar and struts source code
Niall, I am not sure if src/share contains all the .java files corresponding to classes in struts.jar. What happens is that I deleted struts.jar and put all the source files under src/share and then compile all the files in WSAD trying to generate all the classes in struts.jar, and I found one file ActionServlet.java doesn't compile since this class import org.xml.sax.InputSource, but there is no InputSource in the class path. And I also didn't find org.xml.sax.InputSource in struts.jar. So did anyone has chance to include the struts source file to your project instead of just include a strus.jar? Thanks.
