Re: How to disallow opening a page directly from URL
Paul Benedict schrieb: Panak, how are the menu items going to communicate to your application which item was selected? Obviously, by incoking an Action; if the menu items can invoke the Action, so can a user. There is no such thing as security in this case. Just a thought, but probably the Action could check the refer(r)er. If the URL is directly typed in or comes from a Favorite, it should be null. Of course, that's not 100% safe, as nearly everything in the request can be tampered with before sending (using the Firefox Tamper plugin or some proxy like WebScarab, for example). Plus, I never actually tried, for security-wise, it should make no difference whether the user clicks on a link, invokes a Favorite or types everything in by hand.

Re: I've got a big problem:Can NOT insert flash into jsp---using struts 1.1 and Tiles
This is kind of trivial and not related to Tiles at all.
Fact is, your Flash thing or even the image, if you like,
are not found because their URLs are incorrect. Solution
is to specify context-relative URLs like this (JSP 2.0):
img src=${pageContext.request.contextPath}/myImage.jpg
and the like. For older JSP versions, use the c:out or
c:url tags.

Re: Unsupported major.minor version 49.0
Hi, well, the truth may be found somewhere in-between. First of all, each java class has a version stamp, older versions have lower numbers. The JVM is backward compatible, so older classes also run in a newer JVM. Version ranges are as follows: Java 1.1 platform: 45.3-45.65535 Java 1.2 platform: 45.3-46.0 Java 1.3 platform: 45.3-47.0 Java 1.4 platform: 45.3-48.0 Java 5 class files are stamped with 49.0, and the JVM is also backward compatible. So, a 1.3 class file will run in a 1.5 JVM, but not the other way round. That's the reason for the original problem. None of us would be able to run Struts in an 1.4 or 1.5 JVM if it were otherwise, as the binaries are 1.3 versions, IIRC. Apart from that, Sun has been very careful when it comes to JVM version compa- tibility, much more than in other parts, Serialization would be a prominent example here. IIRC there were no changes to the class format in 1.2 and 1.3, possibly in- cluding 1.1 even. The changes made in 1.5 were mostly required by the extended type system (Generics | 'type erasure'). Another aspect of backward compatibility is the usage of features in the Foundation Classes; this lib has steadily grown over the years. If a class files has dependencies on other classes only available in a more recent version, trying to do so will end up in a ClassNotFound exception, but thats just what is to be expected. An example for that would be Tomcat 5.5: normally, it requires Java 5, but you can install a compatibility package that provides the missing features and makes it run in a 1.4 setup.

Home page is not shown if Javascript is turned off. Not even a message. Yep. Wasn't so earlier, but according to the author the project moved to a new provider recently who accepts Spring (the former obviously did not). May go away. In the online samples each page has unique URL, so after going three pages forward one needs to click Back button three times to return where he started. DisplayTag allows to provide URL where to return after each page flip, so you can use a single location for all table pages. Nice :-) Don't know if eXtremeTable can do the same. Of course, you can also specify an URL attribute (is that what you mean?) which is a necessity with Tiles anyway. Grid navigation itself is handled via parameters; don't know how DisplayTag handles this from memory. Anyhow, I've never really missed the single location thing. Depends on the scenario, of course :-) For an example of how a single location works, see MailReader online demo here: http://www.superinterface.com/mailreader Registration bravely accepts password 'a', but complains it's too short at logon. Odd. Shouldn't it be the other way round? At least, the user account is kind of useless afterwards. May also go away :-) Log In as user/pass and select Manage Subscriptions. Subscriptions are displayed in four in a page. You can add, edit or delete subscriptions or flip pages, and you still will stay on the same location, see address bar in your browser. If you click Back button, you will _immediately_ return to main menu, you do not need to go through all subscriptions you viewed or edited. Our general UI policy is that if the user clicks the browser 'back' button, he should see the last page he visited, which usually is the last result page from the datagrid. If he wants to 'bail out', we provide a navigation menu for such cases (Tiles be thanked). Generally, I don't like the 'back' button in web apps too much, in particular in connection with forms. YMMV. This particular table was created with Struts-EL tags; with DisplayTag it would be twice smaller and much cleaner in a JSP code. DisplayTag is fine, eXtremeTable is fine too. We chose it because it sports quite a lot of very useful features, it works, it's easy to use and well-designed. There's a third component available from sf.net named ValueListHandler or so; Matt Raible has an article about eXtremeTable (plus some demos) on his site where IIRC it was mentioned somewhere.

Re: Is there an abstract meta-model of Struts ?
Hi, your thoughts are quite interesting, but unfortunately I don't know about an official MOF and kind of doubt from my own experiences Struts development can succesfully be formalized that way. For instance, many people still think quite differently about the 'M' part; there is no 'official' rule what 'Model' actually means; if Actions (or even Forms!) may be considered part of the Model an so on; I've seen quite a lot in this direction. Struts is largely open to architectural decisions of this kind. Struts provides a standard way for handling web input, based on the existence of a central 'request processor' servlet that delegates the information flow to Action implementations that do the actual work, determine the outcome and return it to the client somehow, plus the ability to manage the exact details declaratively via struts-config.xml and web.xml. But it does not enforce a formal coding or application design paradigm, and that's probably very wise, as Struts is a protocol-near, 'down-to-earth' framework by nature, originally aimed at providing a best-practice solution in a spot that had been left dark by the J2EE specs. In effect, Struts is a different kind of animal when compared to things like WebObjects, Tapestry or JSF which were driven by different design goals. Perhaps Craig can shed some more light on this. -- Chris. NB.

This component is quite good, but requires JSP 2.0 (SimpleTag) and has issues with Tiles (switch off JavaScript and see for yourself).

Its main advanta- ge is the expert usage of JavaScript and DHTML you won't find in other components that soon. So there's still room to improve, but the author obviously has a lot of other projects going on and therefore might not find the time to bring this component from current version 0.81 to final anytime soon (enough). My guess. It just hangs there for at least two months now. Struts-layout doesn't seem to work. Ditchnet seems to be very good however we cannot switch tomcat-5.5 into servlet mode 2.3.

No, I won't call or send a mail, but buy something else in the meantime. Evaluation itself usually costs much more than license fees. Therefore, I just won't evaluate something I may have to drop later for license or other reasons. Can you provide me some alternatives? If you had asked for Tree or DataGrids components, there would be a real abundance of choices nowadays. But the relatively simple TabSheet component still seems to be kind of an orphan to TagLib developers. Still, there are some options. IMHO the best may be *Struts-Menu* which has already been mentioned. There is another component in an (abandonware) suite named ninebits-taglib, IIRC, available from SF and released under the GPL (not LGPL or Apache, so an instant goodbye for commercial projects here). There's another tag available that seems to have been free once, but costs around USD 25 now, if you search the net long enough; I forgot both its name and the URL. Then, there's the ColdTag suite, of course, which also sports a relati- vely simple Tab tag, but costs money for commercial use, as all Coldsuite tags do. If Struts-Menu won't suffice (its good) and as the taglib land seems to be more of an endless plain with very few water spots if your needs are more advanced, this could be one of the few ocasions where one may also look for commercial implementations. My personal favorite in this direction is the common-controls suite (check Google).

Re: What's wrong with DTOs?
[EMAIL PROTECTED] schrieb: +1. The first thing I always preach new developers on my team is that they should think the entire web tier away and replace it (mentally) with a Swing or whatever client, without changing anything in the subsequent layers, and the application still has to work as usual. From an architectural view, the entire OO thing is about loose coupling, separation of concerns and minimizing dependencies. Now MVC - a pattern emerging from its first Xerox in- carnation some 25 years ago, originally invented for SmallTalk-based rich clients and targeted at helping to coordinate keyboard input, 'business logic' (as understood back then, mysteriously named 'Model') and monitor output in a responsibility-oriented way, has since been adapted to different technologies including the web. Still, it's strictly about getting input and showing things from the Model. Now, unlike in the old days, applications are usually architecturally somewhat more complex now- adays and split into different layers (naming varies). Usually, there's at least one layer for the 'business logic' (a.k.a the application) and a subsequent one for resource access. Both of them are relative long- lived compared to the client (web) tier which can change every few years, from Struts to JSF or whatever, whereas the business logic itself tends to stay relatively static (usually the database itself is the part with the longest lifespan, database models easily reaching the age of 30 or more). There- fore, IMHO it's a good idea to keep heed of a strict separation of architectural layers throughout the entire application, providing interfaces like BusinessDelegate or Facade to be used by different client implementa- tions in a consistent way even in case of a complete technology change in the client tier. This may possibly require more work to keep thing as abstract as possible, but I'm quite confident it'll pay some day. And that's where DTOs (or ValueObjects, which originally were designed to address granu- larity issues when dealing with EJB and the like) or domain classes come in. I, for once, don't want to see *any* web-related stuff in my backing layers; no document/view con- siderations here.

Re: [OT] Re: JDeveloper 10.1.3 Early Access
Hi, I think what you mean is a feature named 'Local History' that has been around in Eclipse for quite some time. The new release has a much improved built-in CVS client (10.1.2 still used the CVS binaries which is optional now) and supports other SCMs (ClearCase, Perforce, Dimensions at the time) through Extensions (hopefully, a VSS plugin will be available sometime soon, as we use that). Only played a little with the much-improved code editor (which also has a highly configurable code formatter that actually works, so time to say goodbye to error-prone Jalopy :-), the new refactoring options which are equivalent to Eclipse now, much faster than in 10.1.2 plus *they actually work* (the old 'rename class' feature usually detected only half of the references and was limited to Java files) and imported a larger Struts/Tiles/Spring- based web project; works like a charm :-) -- Chris - Original Message - From: Néstor Boscán [EMAIL PROTECTED] To: 'Struts Users Mailing List' user@struts.apache.org Sent: Tuesday, September 20, 2005 9:22 PM Subject: RE: [OT] Re: JDeveloper 10.1.3 Early Access Hi Dave Haven't got the time to see how it works.

Re: DAOs in service methods
Hi, my suggestion would be to have a closer look at the Spring framework. IoC / dependency injection is really cool once you get a grasp of it. Instead of having the service look up a DAO instance, you simply inject the fitting implementation class into the service via Spring. The service itself only knows the DAO interface and has a setter property for it. Note that this way you also have to deal with shared instances (like with iBATIS DAO) and therefore have to keep heed of thread issues, but luckily Spring also provides template implementations for most common database access solutions (JDBC, iBATIS, Hibernate, JDO, Toplink (by Oracle) which are said (I still have to check that out) to be inherently thread-safe. Btw. can anybody here confirm this? Currently, we are probably too cautious in this direction (using iBATIS). -- Chris. - Original Message - From: Paul Benedict [EMAIL PROTECTED] To: user@struts.apache.org Sent: Thursday, September 01, 2005 6:19 AM Subject: DAOs in service methods Hey guys.

Hm...IMHO one good example would be the JPetstore sample app that comes with the Spring distribution, for instance. Good in particular, as its not overly complex, plus you can compare it to the 'traditional' iBATIS JPetStore app. The architecture has slightly changed (the former 'service' functionality now rather completely wandered underneath 'domain.logic', in the Facade implementation, which is IMHO ok in this case, as it's mostly delegating everything anyway). This is one of the samples I profited the most from when evaluating Spring. Another good starting point would be Matt Raible's AppFuse, which is basically for Hibernate and a little bit more complex. Those two are kind of my 'reference samples' when it comes to Spring :-) Note that in both cases, the DAOs are very lean and don't contain any messy synchronization code. But IMHO the really cool thing about IoC (not to mention the AOP functionality) is that you finally can achieve really loose coupling throughout your entire app, and its simple. In fact, we could replace virtually anything in our current app by a different implementation, declaratively (apart from providing the new implementation class, implemen- ting the same interface). Another benefit is that Spring is non-intrusive by design and you can happily stick to the technology stack you already know it works. For instance, we still use Struts/Tiles instead of Spring MVC or JSF.

What I sell are my skills, work performance and last but not least a significant part of my lifetime, but neither my soul nor my private life.

Stealing silver spoons, including deliberately breaking company rules in terms of e-mail usage and the like is another issue. Personally, if I owned a company and someone was using the company email domain name to post on sites such as swingers or transvestitepride, I think I should have right to terminate his or her's employment. What I have a problem with is ... 1) The inconsistency in what is protected. For example everyone today talks about tolerance. But what does this mean? What it ends up meaning is There are no moral absolutes so the only valid belief system protected is one that doesn't espouse moral judgments. But what about being tolerant to the idea that someone might feel otherwise? Why is state sanctioned secularism the only valid religion (and yes secularism is a belief system - a religion). It's sort of funny that those whom often claim to be the most 'tolerant' are often the most vicious when it comes to attacking someone that disagrees with their view of tolerance. There are many views I could state that would get me labeled as being 'intolerant,' yet, somehow it's supposedly not offensive to state All views on X,Y,orZ are equally acceptable. To me, and many others, that later position can be considered extremely offensive. Why is only one view (secular humanism) considered 'non offensive' but other religious views are some how bigoted and intolerant. It's pure hypocrisy. In Germany, in a major part thanks to the US (I mean it!), religious freedom, for instance, is granted to everyone in our Constitutional Law (Art. 4 GG). Getting fired just because of one's religious views is impossible by law. So I, who believes in Jesus Christ as my personal saviour and follows the Bible as his above-all-worldly-wisdom guide can happily work together with Hindus and common atheists, in- cluding my boss. I can even tell them if they're on the road to eternal doom, the same as they may tell me I'm ridiciously wrong, and still keep my job. And in fact, the Bible is quite intolerant when confronted with modern secularism, but what's my choice? As for general opinions and secular beliefs, we have Art. 5 GG which grants freedom of speech. So there's no need for hypocrisy here at all.

Now, this may not be too helpful, regardless of whether 'BD' means Business Delegate or is a typo for 'DB'. In fact, I would prefer the first alternative, as that would indicate Patterns usage and proper architecture. Anyhow: one crucial thing that should come instantly to mind is that - with Struts or without - forwards (Servlet API) are limited to the same JVM, often, the same Application context, as they are handled internally by the server. In any other case, one has to use a redirect (issuing a HTTP code that points the browser to the actual target). Then, there's none of the three scopes available for passing parameters, so you have to transmit them by ordinary HTTP means, in this case, as GET parameters appended to the URL; properly encoded (response.encodeRedirectURL(), was it?). There is no real problem if you *just* redirect (static), as there is a redirect attribute to forward in struts-config.xml. But this is a 'static' mapping. If you want to transfer dynamic parameters to your external application, AFAIK you have to build the target URL (parameter string appended) yourself, and I still wonder what may be the best approach in this case. Options are: 1.) coding the redirect manually 2.) overriding the Struts mapping with the parameter- enriched target URL at runtime or 3.) taking the basic URL from the mapping, appending the parameter thing and then proceed as in 2.) To be honest, I'm not sure what is best practice in this case, and in real life, I often just fall back to 1.).

Could you elaborate please? Is this a Servlet model security problem,
one specific to Struts, or one that is only exposed by neglect in

used path mapping all my Java life. I've also posted numerous
path-mapping strategies on this list (as have others) and never have
encountered any warnings like this.
Well, after checking, it's actually p. *3*62ff. There Hans says: The
extension rule, using the expression *.do, is the one that's
recommended for for mapping requests that should be processed
by Struts (after explaining the different kinds of rules (exact match,
longest path prefix, extension). On p. 363, he says, after giving
some example: It turns out, however, that even with a separate
mapping for protected resources, it's easy to bypass the the
access control for a Struts action when you use the path prefix
mapping. I'll show you why in a moment. To avoid security issues,
I recommend you stick to the extension-mapping model. Of
course he shows, as always, from p. 364 on. It all starts with
a simplified version of Struts 1.0.2 code:
protected String processPath(HttpServletRequest request) {
String path = null;
path = request.getPathInfo();
if ((path != null) (path.length() 0)) {
return (path);
}
path = request.getServletPath();
int slash = path.lastIndexOf(/);
int period = path.lastIndexOf(.);
if ((period = 0) (period slash))
path = path.substring(0, period);
return (path);
}
Then he goes on: The processPath() method first calls
getPathInfo() on the request object to get the part of the
path that remains after removing the part the container
uses to identify the servlet. For instance, with a path-
prefix mapping such as /ch18/protected/do/* for
the Struts servlet in the deployment descriptor and
a URI such as /ora/ch18/protected/do/StoreMsg, the
getPathInfo() method returns /storeMsg. If it returns
null, it means that an extension mapping is used for the
Struts servlet or that the URI is invalid. If so, the the
getServletPath() method is called to get the complete
context-relative path for the request. With a mapping such
as *.do and a URI such as /ora/ch18/protected/StoreMsg.do,
it returns /ch18/protected/StoreMsg.do. The processPath()
method strips off the extension part and returns the rest
of the path, i.e. /ch18/protected/StoreMsg.
Hence, when you use the path-prefix mapping, only the part
of the URI that comes after the part that identifies the Struts
servlet is returned an subsequently finds a matching action,
while with an extension mapping, the whole context-relative
path is returned and identifies the action. This is what causes
the security problem I mentioned earlier. With the access-
control filter mapped to /ch18/protected/*, and the Struts
servlet mapped to /ch18/do/* and /ch18/protected/do/*,
an adventurous user can access a protected action with a
URI like /ch18/do/storeMsg instead of
/ch18/protected/do/storeMsg, completely bypassing the
access-control filter. This means the only secure way to
to provide access control for Struts actions when you
use path-prefix mapping is to do the access control
within the actions instead of with a filter. It's easier to
just stick to extension mapping, as I recommended
earlier.
So much for now. Filters aside, I think it's more of
a general configuration trap, and probably things
have been changed sind 1.0.2 anyway. Still, we
at least prefer everything we want to channel
through the Struts servlet have a *.do (or what-
ever unique) ending, regardless of path issues,
as not losing track of mapping details is an ongoing
challenge with larger apps in general, and the
last thing I'd like to care about are additional
security considerations of any kind :-)

If your application doesn't have the huge performance requirements that frames can help with, why bother using them at all? Well, I generally hate frames too and rather extensively use Tiles. Still, there are situations where frames are better suited (IFRAMES, even), as they can improve user experience. Think of a search mask, embedded in a Tiles-generated View. The visual design guys stubbornly require to present the search results being presented as a 'scroll box', fixed size, scrolling contents, pagers or anything in this direction are a no-go. Two approaches are possible: the DIV tag solution where the whole page is generated again (DIV can be told to scroll if needed), or the IFRAME alternative which is much more difficult to handle, as you have to deal with two pages in a single (Tiles-based) View which you have to keep in sync. For comparison, I implemented both, and both solutions finally worked as desired. But: while the single-page DIV tag thing briefly, but still noticably, flashed upon each requery, with the IFRAME solution, everything except the 'result window' kept steady, just as in a normal GUI app. So finally the IFRAME solution won. From a developers's view, I always would prefer a 'single page' solution, but then, it's the user who decides if he likes the page or not. I must admit the IFRAME thing gives a much better user experience, so I would be reluctant to totally condemn frames. Furthermore, FRAMES | IFRAMES are the only way to transparently embed contents from your server into another server's pages (think of portals written in PHP or the like), which may well be a point when it comes to monetary things (JSTL provides a tag suited for such situations, but in my experience, very few portals actually run on Java, and even fewer of them are JSTL-capable).

Looks like I went a bit over the top with the embedded html proposal.
It seems the users would be content if whatever they'd keyed into a
text-area looked the same when subsequently re-displayed as text in a
document.
ie just preserve the line-feeds, no need for bolding etc.
Any ideas?
If you want someone to see the visualized text as they are typing,
you're going to need something like a rich text component that
does that sort of thing in JavaScript. The standard HTML
textarea element
that Struts uses doesn't help you, even if the HTML elements are
literally embedded.
If you are taking content and then literally embedding it in your
page with something like bean:write, you can turn off the
filtering by saying filter=false in the attributes of this tag.
Be aware, however, that in doing so *you* are taking responsibility
for avoiding cross site scripting attacks from potentially
malicious users that try to embed JavaScript markup. Most likely,
you'll need to scan the text and only allow HTML elements that are
reasonably harmless (like b).

Hi All,
I have a struts app that lets users input into text-areas.
Whatever the user entered will later be displayed as text. To give
users some control over presentation, I'd like to allow them to
enter html directly into a text-area. Struts appears to convert
all html to harmless displayable text, so that hr appears quite
literally as 'hr' rather than as a horizontal line.
How can I allow users to input effective html? And is there any
way I
can
ring-fence what they enter, so that any html errors they make
don't
bring
the whole page down?

Therefore, one usually provides an html:submit with each form declaration. You can achieve the same with JavaScript, which you probably do here, but if you say something document.forms[0].submit(); document.forms[1].submit(); the second line won't be executed anymore, for the browser has already started a new request.

Basically, JDev 10g is an 'xcopy' install; everything comes in a huge .zip archive and only has to be extracted to some directory. Then find the /jdev/bin subdir and check jdev.conf. Uncomment the line starting with SetJavaHome (in my version, it's line 94) and change it to pointing at your JAVA_HOME. That should be it. After all, I'm running the Windows version this way at home under SuSE 9.0, for I didn't want to download twice, and I strongly suspect all those different versions just contain the same files in the end. So I ended up with a surplus Windows JSDK (in the /jdk subdir) which can be safely deleted under Linux, but otherwise it runs just perfectly. HTH, -- Chris NB.

The one you submit ends up in the request, and html:form gets renderered to just a normal HTML form tag in the end. On to the beans. I'm not sure what kind of bean you mean here. If it's the form bean (and it's the same table), try referring to it in your second html:form via the token you used for the first one. If we're talking about two different beans here, you have to make sure both of them are actually there and bear different token names.

Re: still about jsp:include

Hi,
probably I don't fully grok what's your exact
problem. What I get is that you have an iframe
plus a jsp page that's intended to be displayed
there. Forgetting about the iframe for the
moment, let's have a closer look at my.jsp.
I see a form that calls something, but also
an input tag outside the form declaration.
Then, there's JavaScript code that submits
the form. This, even if it works, is improvable
style. input tags should be embedded in
forms, and a button that does a submit
should be specified a such (type=submit).
Doing so would not only relieve you from
being dependant on JavaScript (which always
should be considered as something 'on top'
and not available in a web application, for
the user can easily turn it off), but achieve
the same behavior in a HTML specs compliant
manner. Fix this first. Then, considering the
action declaration, you may successfully update
myjsp.jsp this way, but the iframe on top
may not get aware of the change. You have
to update the whole page and have the iframe
load the fresh content implicitly. Don't know
where the 'session already commited' error
stems from, but this seems to be another
problem and neither related to Struts or
the Servlet API in general. I hate iframes,
but have done them in and out. As I already
started citing www.anwalt4you.com here,
I'll stick to it, and it just happens the SearchEngine
module uses an iframe for displaying seach
results. It definitely works (but also uses
JavaScript :-(, you can look at the HTML
sources how I did it in the end, for I forgot).
Anyway. All in all, I doubt your problem is
related to JSP includes in any way. If you're in
doubt, we heavily used Tiles, and that is just
a (brilliant) enhancement of the
RequestDispatcher.include() mechanism
which is the basis for the jsp:include
tag as well. But fix the other problems
first.
HTH,

I mentioned this problem here days ago, and I asked the difference
between redirect and forward here yesterday, but I m still at a loss
to know why I got the exception
see: my.jsp is my jsp file , it exists in another jsp file which
refers myjsp.jsp by an
iframe ,that is iframe src=myjsp.jsp/
my.jsp
form name=myform action =/myapp/myaction.do target=_self
...
/form
input type=button value=submit onclick=submit()/
jsp:include page=myhtml.html/
script
function submit()
{
myform.submit();
}
this is my action mapping
action path=/myapp/myaction
type=com.mypackage.myaction
name=myform
scope=session
forward name=success path=/myjsp.jsp/
/action
the action myaction does nothing than to modify the content of
myhtml.html so when I forwarded back to myjsp.jsp, it shows different
content.
I clicked the button on my jsp page, it throws response already
committed exception, why?
and it indeed doest now always throw the exception, but it throws
actually sometime.
I really want to know why, can anyone help?

Re: Complex validation

That said, I usually validate twice, once in the Presentation tier and another time in the Business Logic, and I almost never use or even rely on JavaScript, but do strict server-side validation for that's a secure area (while JavaScript can be easily turned off). IMHO it's preferable to have the user spend an additional roundtrip in case of inconsistent data and issue some consolidated warnings in red than pre-checking on the client tier via JavaScript which ends up in a nameless message box. So for me, the Validator generally is a good thing (and crucial when using DynaActionForms), but upon finding out it also has definite lackings when doing complex validation, I dropped the entire DynaActionForm approach and went back to traditional ActionForms. For I found that I finally was spending more time on Validator XML definitions than it takes to generate the entire ActionForm class itself (Oracle JDev and NetBeans have a really useful Beans editor here) and just code the necessary validation code by hand. The advantage is that I can see what's happening directly in the Debugger instead of endlessly interpreting log files and adapting boring XML definitions. But it's a matter of taste, after all, as always. HTH, -- Chris. Hi everyone. I need to perform conditional validation in one of my forms. I have a drop-down list and a text field.

Re: struts and tiles seem not to like each other

Hi, After diving into the world of struts I decided also to include tiles in my app. But there seems to be something that keeps me from doing this. Here are the steps I have taken so far: checked struts-config.xml for tiles-stuff (as I copied that file from struts-blank everything was already there): controller processorClass=org.apache.struts.tiles.TilesRequestProcessor / plug-in className=org.apache.struts.tiles.TilesPlugin set-property property=definitions-config value=/WEB-INF/tiles-defs.xml / set-property property=definitions-debug value=6 / set-property property=definitions-parser-details value=6 / set-property property=moduleAware value=true / set-property property=definitions-parser-validate value=true / /plug-in From what the docs say that part seems ok (at least to me). Step 2 (tile-defs.xml): tiles-definitions definition name=tiles.login path=/pages/layouts/default_layout.jsp put name=header value=/pages/header.html / put name=content value=/pages/Login.jsp / /definition /tiles-definitions all the files mentioned here are where they belong. Step 3 (global-forward): As I want my startpage (index.jsp) to forward to a tiles-page I created a global-forward in struts-config.xml: forward name=login2 path=tiles.login / also tried forward name=login2 path=/tiles.login / and added a logic:redirect forward=login2 / to my index.jsp. So far so good. When I try to access the app. (via index.jsp) I receive the following message: type Status report message /portal/tiles.login description The requested resource (/portal/tiles.login) is not available. btw. portal is the context. To me this seems as if struts does not know the tiles definition (or at least does not handle it correctly). The application runs in a Tomcat 5.0.19 container (struts 1.1), and no further error-messages are sent to the logs. Maybe somebody knows how to get out of this trouble. Thanks in advance.

I'd have the getter format the Date as a string (use SimpleDateFormat.format(), you can specify any of a wide variety of formats). Likewise, the setter should accept a string and use SimpleDateFormat.parse() to turn it into a Date.
