Validator framework with indexed properties
Hi, I was hoping that the following should work ... but I guess I am missing something somewhere.. validation with other properties is working fine.. but not with the indexed properties. Struts-config.xml: validation.xml: I am trying to validate the indexed property of the completionDate of educationDetails. I have all the following entries in my validation.xml in the hope that atleast one of it will work... but none seems to... datePattern dd/MM/yy datePattern dd/MM/yy datePattern dd/MM/yy datePattern dd/MM/yy datePattern dd/MM/yy datePattern dd/MM/yy datePattern dd/MM/yy Note that I am successfully able to validate other fields on this form like studentEnquiry.firstName etc it is not validating only the indexed properties. If it matters... I am using struts 1.1. Please let me know what I am doing wrong. Thanks much. Regards, Raghu

Re: Reporting Tools
It depends on what you are looking for. I have used both, and think they both suck. :-D Jasper has the advantage that it is free, but usability is crappy. Crystal has the advantage that it usually works, but requires a windows PC to modify the reports. Choose the evil you prefer. ;-) On a side note, if you are looking to support something more printable than html, the jexcelapi project provides a decent and easy to use excel format. I tried FOP to create PDF files several years ago, but at that time it was a massive CPU/memory hog...it may be better now. A google search on "java pdf creation" will also turn up a TON of info...

Well, that's really easy, just do: "request.getSession().setAttribute(Globals.LOCALE_KEY, new locale(languageCode));" in your action, where languageCode is the locale you wish to use.

Note that there is a LocaleAction specifically for doing this, so you don't even have to remember how :) It appears in 1.2.4 at least, but I'm not sure when it was first introduced.

Re: Reporting Tools
Datavision is another decent choice: http://datavision.sourceforge.net/ On the home page there is a link to an article I wrote about using it in a webapp (straight servlets). I've used it in Struts apps too, it's trivial if you use the article (and the accompanying sample code) as a starting point. It's not quite as feature-rich as Jasper or Crystal, but it gets the job done pretty well, can output to a number of formats (HTML, PDF, etc.) is free and is extremely easy to work with.

Re: jaas authorization with struts
Hi Raghu, Laurie, I did a project recently which used the Acegi security project which comes bundled with Spring, and although I was never involved in the implementation of it myself, I heard that it was effective. Am I correct in assuming though that it does not offer the alternative that Raghu was looking for, despite the fact that he(you) seems very positive about it? I can't see how such a security requirement can be implemented in any other way than via the database. It is simply a question of data visibility, in other words, who the data is visible to and to whom it is not visible. The best you can do as far as I can see is to optimise the caching, especially if the relationships are relatively stable. Or is this perhaps a pattern that I am not aware of?

However the definition of resource is the "traditional" action mapping. However I have a requirement which goes beyond that. I have a centre based roles. Let us say my application could be used by administrators at three centres. The trick is that all of them can view the set of "resources"... but in a particular JSP they are authorized to use only certain values for some of the fields. For example, a Hyderabad administrator can view reports pertaining to Hyderabad only and should not be allowed to see reports of Bangalore centre. Which let us say in UI terms would translate to a dropdown of cities .. for the Bangalore administrator... he probably can see the dropdown populate with Bangalore... the Hyderabad admin sees it populated only with Hyderabad and a HeadOffice admin sees all the cities in the cities dropdown. What is the best way to achieve this? One approach is to create a separate role for each centre user. For example... have a role called Bangalore_Admin and Hyderabad_Admin etc. But obvious drawback is that this approach won't scale well with the increase in the number of centres. The other approach I was thinking is writing code myself. Introduce a column for centre in the user table. From the request.getUserPrincipal().getName() funcion I determine the user... hit the database to determine the centre and then filter the cities based on the city and the role. I don't like this approach because I have lost the advantages of a declarative style of defining security permissions. Also, now my authorization code would be mixed allover and would be difficult to change the authorization policies on a later date. The third approach is similar to the second one. Instead of defining a centre at the user level, I could do it at the user_role mapping level. User1 is the administrator of Hyderabad centre. He could be a regular user for another centre (say Bangalore). Slightly better than second approach but suffers from similar problems. Is there a way that my getUserPrincipal() can be made to give me this extra piece of information about the centre? That would make my code look lot cleaner.

try {
response.sendRedirect("home.jsp");
} catch (IOException e) {
e.printStackTrace();
}
I am using JAAS Basic authentication on tomcat. When the above code is
executed and the redirection happens back, i expected that login box will
pop up again asking me my user id and password. But nothing of this sort is
happening.
When I first time hit the home.jsp .. the box pops up and authenticates me.
Should I not expect the same behavior from the above code. which first
invalidates my present session and then sends a redirect to the home.jsppage?
Can someone throw some light on what is happening?

Re: struts & javascript question
You can use Struts Validator via validation.xml. In that case, validator already supplies the validation code; you would only need to write your own validation for things validator can't check for you. If you want to do your validation on the server not the client, the validation would be written in Java. validator supports producing Javascript for client side validation, but there's nothing in base Struts to execute Javascript on the server. You'd need to look into something like BSF or something if you really want to write Javascript but run it server side. L. Srinivas Jadcharla wrote: Iam sorry i have no idea abt DynaAction forms.

Since I have Struts 1.1, I looked at http://archive.apache.org/dist/struts/struts-1.1/ to see if there is something for Servlet 2.4/JSP 2.0, but it doesn't look like there is such a version here am I looking at the wrong place? I do have struts-el.jar (must be a jar corresponding to contrib/struts-el). I just removed it, which resulted in: Unable to load tag handler class "org.apache.strutsel.taglib.html.ELFormTag" for tag "html-el:form" Makes sense, html-el can't find the Java classes it needs. > Go back to the original Struts tags, and use a JSTL 1.1 > implementation > with them... the container will evaluate the expressions, you no > longer need Struts EL to do it for you. Not sure what you mean by "original Struts tags" and "use a JSTL 1.1 implementation with them". I believe I have the regular, Struts 1.1 taglibs and the JSTL 1.1 taglibs I have (c:out & friends) are working fine in servlet 2.4/JSP 2.0 container.

You're almost there... just get rid of Struts-EL entirely, you only need what's in struts.jar. What's in your <@% taglib ... %> directives at the top of your JSPs?

I had this: <%@ taglib uri="/WEB-INF/struts-html-el.tld" prefix="html-el" %> Changed it to this: <%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html-el" %> And now things seem to work.

Re: jaas authorization with struts
Actually, Acegi does offer what Raghu was looking for (or at least one possible route to achieving it). One of the things it can do is automatically filter collections to remove items the current user shouldn't be allowed to see, so you don't have to bury that kind of business logic in your database. Since it lets you do this declaratively, it's easy to change with changing business requirements. L.

Re: jaas authorization with struts
It does rely on Spring, yes, but getting Spring to co-exist with Struts is trivial; you don't need to change any existing code to do that, though once you have Spring available you may well find yourself wanting to take advantage of it ;-) L.

Re: jaas authorization with struts
Something that removes items from collections according to data visibility constraints declaratively must be quite complex. Presumably the collections are declared in a Spring-style context factory? And then you would have to declare which property of the item provides the IDs, and you also declare a set of IDs which each role has visibility of? Can you provide an object reference in Acegi config with a callable method that will return the IDs required? Or am I wide of the mark here? rgds Adam Laurie Harper on 20/11/05 23:38, wrote: Actually, Acegi does offer what Raghu was looking for (or at least one possible route to achieving it).

Re: session.invalidate doesnt log me out...

Hi,
Shouldnt session.invalidate() log me out?
request.getSession().invalidate();
try {
response.sendRedirect("home.jsp");
} catch (IOException e) {

}
I am using JAAS Basic authentication on tomcat. When the above code is
executed and the redirection happens back, i expected that login box will
pop up again asking me my user id and password. But nothing of this sort is
happening.
When I first time hit the home.jsp .. the box pops up and authenticates me.
Should I not expect the same behavior from the above code. which first
invalidates my present session and then sends a redirect to the home.jsppage?
Can someone throw some light on what is happening?
Thanks.

The problem is that there's no way to tell the browser to relinquish
HTTP authentication info, so when you redirect your app sends an
authentication challenge and the browser automatically responds with the
credentials you supplied the first time. There's no way to force
browsers to prompt again. That's one of the drawbacks of using HTTP
authentication.

To answer the question I can see: - to forward to the input page in an action, use code like the following: return mapping.getInputForward(); You define what the 'input page' is with the 'input' attribute of your action mapping in struts-config.xml. By default, this will do a server-side redirect, so the browser's location bar will keep whatever URL it had to invoke your action. L.. But the input page in struts-config.xml cannot be set dynamicaly. I don't know the name of input page. It could be whatever, it will change. Any idea? There's no reliable way to find out what page you were on before the current page, unfortunately. You have to track that somehow yourself.

Sync session across webapps
Hi, In my web application there are 2 webapps and single login for both. And in UI we are given links to different modules of both webapps. Actually the end user is not (should not be) aware of 2 webapps. The problem what I am facing is, If someone try to work/use continuously in one webapps and try to click a link from other webapp and if it exceeds the session timeout period then user is forced to login again. Is there anyway to avoid this OR is there any way to synchronize session across webapps ? I am using Tomcat 5.5.7 and Struts Framework 1.1. Thanks in advance... Mathew
