Re: Struts 2 - Repopulate controls when validation fails
Hi, 2008/6/26 bob fuller [EMAIL PROTECTED]: The approach I am taking is from the Struts 2 FAQ... http://struts.apache.org/2.x/docs/how-do-we-repopulate-controls-when-validation-fails.html Why should it be avoided? I don't remmeber exactly why, someone on this group mentioned that. In my opinion, using Preparable interface is a better option, but maybe I'm wrong ;-) Regards -- Lukasz http://www.lenart.org.pl/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Multiple action declarations with the same Action class
Hi,This is my first post to the user list.We have started working in struts recently.Is it possible to use one Action class for multiple action declarations in the struts-config.xml?Consider the code below:action path=/action1 type=com.sample.app.TestAction name=formBean1 scope=request forward name=actForward1 path=/test/pages/page1.jsp//actionaction path=/action2 type=com.sample.app.TestAction name=formBean2 scope=request forward name=actForward2 path=/test/pages/page2.jsp//actionaction path=/action3 type=com.sample.app.TestAction name=formBean3 scope=request forward name=actForward3 path=/test/pages/page3.jsp//actionaction path=/action4 type=com.sample.app.TestAction name=formBean4 scope=request forward name=actForward4 path=/test/pages/page4.jsp//actionThanks Regards,Chandramouli P. _ No Harvard, No Oxford.

Yes. You're right. Thank you very much.

fileName is a field of my action class.
When filename contains no spaces, everything goes fine. But if filename is

the browser shows that the file is hello. I'm sure that the filename is
correct in my action class because i logged it out.
Any idea

What I just did---and it worked---was to remove the abstract property setter from the abstract generified parent class. While the abstract getter is essential in the abstract parent (because used by other methods in the parent), the setter was not. (I should have seen that one earlier!!!) In other words, at my end, the pressure's off my back. Though I am still puzzled by the fact that the presence of an explicit converter wouldn't have solved the situation...

RE: How to read data from nested list elements
Guys found the solution
Check the usage of nested tags that can handle any levels.

Subject: How to read data from nested list elements
Hi Folks,
I have particular requirement where I have nested elements and within that
again some elements… So the nesting is up to 3 levels.
Top most element is
ModulesList= it has N modules
Module = it has N Parts
Part= it has N Elements
Here is the class hieirarchy
Parent class that holds all modules.
public class FSModuleListForm extends ActionForm {
private List mModuleList = new ArrayList();
public List getModuleList() {return mModuleList;}
public void setModuleList(List aModuleList) {mModuleList=aModuleList;}
public FSModuleForm getModule(int index)
{
return (FSModuleForm) mModuleList.get(index);
}
public void reset(ActionMapping aMapping, HttpServletRequest aRequest)
{
super.reset(aMapping, aRequest);
moduleList = new ArrayList();
for (int i=0; i 25; i++)
{
mModuleList.add(i, new FSModuleForm());
}
}
}
==

moduleId = -1;
moduleName=null;

moduleLabel=null;
partsList = new ArrayList();
//Lets initialize the list
for (int i= 0 ; i 10; i++ ){
partsList.add(i,new FSPartForm());
}
}
public FSPartForm getPart(int index) {
return (FSPartForm) partsList.get(index);
}
public void reset(ActionMapping aMapping, HttpServletRequest
aRequest)
{
partsList = new ArrayList();
//Lets initialize the list
for (int i= 0 ; i 10; i++ ){
partsList.add(i,new FSPartForm());
}
}
}

partFootnote=null;
elementList= new ArrayList();
//Lets initialize the list
for (int i= 0 ; i 20; i++ ){
elementList.add(i,new FSElementForm());
}
}
public FSElementForm getElement(int index)
{
return (FSElementForm) mElementList.get(index);
}
public void reset(ActionMapping aMapping, HttpServletRequest aRequest)

Re: [s2] Whats the most strutsy way of doing....
Hi Jeromy, Thanks for the comments. I'm trying to steer away from javascript for the solution in order to maximise browser compatibility (this app may be used on older mobile phones). I'm hoping that AES encryption isn't cracked ;), and by the inclusion of some random noise in the properties list it should reduce the chances of a simple brute force attack by increasing the length of the encrypted data and not making the plain text obvious. I can understand the problems with your plugin, My architecture stores only the userId in the session and gets the user from the database as needed (due to the back end being JPA/Hibernate and the user having ManyToOne and OneToMany relationships I can't simply store the user in the session). The system I'm going to implement will decrypt the data from the cookie, verify it as valid, and then populate the session with the neccessary information, all of which will be serializable objects (Long, String, etc.) Thanks again, Al. Jeromy Evans wrote: Al Sutton wrote: Dave, I'm completely agree it's a great idea and useful thing to do, but the problem is what to put into the cookie and how to map it to the user. My current favourite is encrypt the properties you want to store (using AES for speed and JCE support), then decrypt and inject when needed. Cookies should be considered limited to 4K (due to the joys of RFC2109 Section 6.3), so as long as the data fits joy shall be mine :). Al. Hi Al, Just another variation I use where the useragent requires javascript: authenticate the user and generate a token; the token doesn't contain any sensitive data; the token is saved in a cookie and included in all requests (as cookie, header or param) an s2 interceptor checks the token is matched to an authenticated user. it injects relevant details to actions (eg. a store maps tokens to users; server-side manages expiry, concurrent logins etc) It's not as fast as encoding login information in the cookie but it can't be broken. I use the same method to sign XHR requests. If the user has checked the remember me box the javascript gets the token from the cookie and resumes using it. The server it knows not to invalidate that token. Vulnerabilities: - The token should be unguessable to minimize forged requests; - as javascript is inscecure, tokens can be stolen from the cookie (eg. by an advertisement, XSS) I wrote the above as an S2 plugin. The only problem with releasing it as a plugin is that the service that checks tokens can't be Xwork'@Inject'ed into the interceptor (rather it has to be injected via spring or guice) due to its potential external dependencies (eg. an EntityManager). The same plugin also allows me to apply roles to action methods (jsr-250). cheers, Jeromy Evans - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Hi Lukasz, I moved it and now it works!! Great man, thank you very very much! I hope that everything else will work good with this pattern ;-). No, my Acegi is not using JPA, it uses just basic (applicationContext-acegy-security.xml) configuration. I think that this solution should be added somewhere in that Struts 2 + Spring 2 + JPA + AJAX application example, because a lot of people will have the same problem. -- Thx one more time, Milan Lukasz Lenart wrote: Move OpenEntityManagerInViewFilter mapping before Struts2 mapping like below filter-mapping filter-nameSpring OpenEntityManagerInViewFilter/filter-name url-pattern/*/url-pattern /filter-mapping filter-mapping filter-namestruts2/filter-name url-pattern/*/url-pattern /filter-mapping If Acegi also use JPA. move OpenEntityManagerInViewFilter to the top.

I think that this solution should be added somewhere in that Struts 2 + Spring 2 + JPA + AJAX application example, because a lot of people will have the same problem. The right order is already in the example, you made simple mistypo ;-) Best regards -- Lukasz http://www.lenart.org.pl/ - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Submitting a collection to Struts action
Hi, you have multiple options.
