there is NO need for adding table-specific-html
(eg. trtd) during the loop,
like
html:iterate
trtdbean:write ...//td.../tr

Craig, can you elaborate on this a bit more? I'm confused
because if
you went with a different front end presentation other than JSP and
Struts HTML form tags, why would it matter that you chose
Struts HTML
tags for the JSP portion?
If you choose Struts HTML tags for your presentation, you're
stuck with
what Struts provides. Since Struts has no user interface component
model of its own, that has led to a variety of ad hoc solutions for
more complicated requirements.
If you choose JSF components, not only are you not stuck with what
Struts provides (because the JSF API standards are common --
and there
will be ***lots*** of third party components built on top of this
standard), you're not stuck with JSP either. See below for more.
If you later chose an XML/XSLT or Velocity
(yuk:)solution for your view you'd end up scrapping the JSPs
altogether anyway so why would it matter what tags you used
to build
the JSPs that you would be replacing? Or are you basically
saying to
not even bothr using JSPs for a front end view? (I've seen good
velocity templates and I'll take a *clean* JSP using JSTL and tags
over Velocity any day of the week). Thanks for your
thoughts and all
your work on Struts, JSF, Tomcat, etc.
The Struts HTML tags are very much specific to JSP ... indeed, their
very implementation is as instances of JSP custom tags. You
can't use
them at all without buying in to JSP as a display
technology. And, for
various reasons, more than a few loudmouths :-) in the Java
community
do not like JSP at all.
With JSF, however, the situation is different. Every JSF
component is,
at its core, just a JavaBean ... it doesn't care what technology is
used to ultimately manage the page. Yes, we provide JSP tag
wrappers
around all the standard components (because that addresses
the need of
a very large portion of the marketplace), but it's not
required. The
reason is that JSF provides a pluggable ViewHandler
implementation ...
the default one does RequestDispatcher.forward() calls (just like
Struts does), making it very easy to use JSP, but this is by
no means
required.
You like Tapestry style separation of the component tree definition
from the static HTML text? That's not hard ... go get
Hans's JSF book
and read the last chapter, to get you 80% of the way to a robust
ViewHandler solution.
Maybe you'd prefer XForms? Go for it ... writing a ViewHandler that
transforms your favorite way of representing a component
tree into an
XForms document is MMP (Merely a Matter of Programming :-).
Or, maybe you'd prefer an XML based solution that has all
the component
stuff in a single file, and you're contemplating an XSLT
based solution
that transforms component definitions into the corresponding
HTML. Go
for it. (Of, course, if you use the XML syntax for JSP
pages plus JSF
component tags, you get this pretty much for free ... oops, sorry,
forgot you might be one of those that doesn't like JSP :-).
The basic point is, JSF is not restricted to using JSP as
the view tier
... although, for obvious market share reasons (the number
of current
Java developers that use JSP dwarfs the number that use other view
technologies) JSF makes this very easy.

No, that's *not* at all why Struts was created.
The primary reason Struts was created was to enable application
developers to employ a web application architecture based on
model-view-controller principles ... in particular, enabling the
separation of the controller tier from the view tier. When Struts was
created, there were no commonly accepted design patterns for that
separation.
The custom tags that Struts provides (in the html and logic and bean
tag libraries) were a necessary precursor to out of the box usage of
Struts, in order to make it possible to adopt the basic MVC
architectural pattenrs. However, that was *always* a secondary
feature in the original vision -- the important part was separation of
the view tier logic from the business tier logic.

Re: [OT] JBoss, Jaas and Struts
Dang I thought I was onto something! I guess I'll stick to my User object in each session, and just try to make sure I centralize the auth checks as much as I can. Dunno why I ever wanted to change it, anyway. Thanks Craig for your time. Erik Craig McClanahan wrote: On Sun, 18 Jul 2004 21:50:19 -0400, Erik Weber [EMAIL PROTECTED] wrote: So, I am trying to use the JAAS implementations that JBoss provides, which are configurable via login-config.xml. Now, if you configure that file appropriately and create a login page that follows the J2EE specs for container-managed login (the form action is j_security_check, the username field is called j_username and the password field is called j_password), the container does indeed propagate the authenticated subject to the web-app environment somehow; you can use the methods such as request.isUserInRole successfully. However, with the form action having to be set to j_security_check, you lose the link to the Struts controller, and thus give up Struts stuff like form validation, error redirecting, etc. That is as it should be. When you create a form login page (for container managed security), what you are essentially doing is designing a page that is part of the *container*, not part of your *application* -- in other words, the only thing you get to do is make the login page visually look like the rest of your app. It is not, in any way shape or form, actually part of your app. Therefore, you can't assume things like Struts validators. To grasp this more fully, switch your app to use BASIC authentication instead of FORM, so that the browser pops up its login box. See how you don't have any way to specify validators on the input dialog, or control where the input goes? That's because form based login is an exact analog to that procedure. So I toyed with the idea of bridging my Struts login page (action != j_security_check) with the container, by somehow processing the form submittal on my own, but then forwarding the username and password as j_username and j_passsword to this j_security_check resource, but I couldn't figure out how to do it. I even went so far as opening an HttpURLConnection to http://localhost:8080/j_security_check; and setting the username and password as request parameters, just to see if it would work. Yeah, it's been a long day. Anyone have an idea on this approach? Yah, I do ... give up on expecting any portable solution that will work across servers. The current specs do not provide for that, although there are current JSRs under way to address that precise concern. So I went the route of the typical examples; I wrote a login Action that instantiates a LoginContext using the domain I have configured in login-config.xml, provided my own CallbackHandler to submit the username and password, etc. And the login method does work -- it does authenticate using the database I specified in login-config.xml, but yet somehow the Subject is not propagated to the web-app environment the way it is when you login using the form action j_security_check, and so I still cannot use the methods such as request.isUserInRole. So obviously whatever intercepts the call to j_security_check is not only doing authentication, but it is taking some extra step to let the container know that the user has been authenticated. I know this is true because the request.isUserInRole method works when I do it that way. I iterated all the session attributes and there are no new ones present after authenticating with j_security_check. Does anyone know what this missing step is, and how I can do it from my own code? Or am I wasting my time? If you want to use Struts features in your login page, you'll need to abandon container managed security. Perhaps something like SecurityFilter (a sourceforge project) might be useful to you -- but, if you're using EJBs and need the propogation of user identity from the web tier to the EJB tier, this is not likely to work. The only possible solution would be something your app server itself provides. Thanks if you even took time to read this!

validatewhen with a regular expression
Is is posible to use validatewhen in conjunction with mask?
I cannot figure out how to make it work. Separately they work fine, but
when I try to use them together it never validates.
Here is the non-working config.
form name=dynaPhoneNumberForm
field property=phoneNumber depends=validwhen,mask
arg0 key=phoneNumber.displayname /
var
var-nametest/var-name
var-value(submit == 'delete') or (*this* !=
null)/var-value
/var
var
var-namemask/var-name
var-value^\d{4}-\d{4}$/var-value
/var
/field
/form
I'm using a LookupDispatchAction, and if I am calling delete, I do not
send the phoneNumber field. If I am not deleting, then I would like to
validate this against a regular expression.
And, yes, the regex is working OK - they are not U.S. phone numbers.

Re: struts response character encoding.
There this system property you can set but I can't remember it, it's used as the encoding to use when reading files... Anyway, I always edit my .jsp and .properties using UTF-8, then pass them through the native2ascii ant task during my build. It's just a wrapper for the same-named JDK binary; you can use that directly if you dont use Ant.

I have a struts version bundled with Appfuse, all I know is that it is from 2003-12.02 (that is 2. december).

As a historical consequence, however, I for one think that this turned out to be the more revolutionary result of struts, leading coding into taglibs in a way not seen before. The controller and MVC (of sorts) pattern in Struts existed in all sorts of forms prior to Struts. Struts did it better than most, maybe better than all the rest, and provided a standard that people could code to. But, those tags were just a big surprise in the way they hit the market. I, for one, now code tags as readily as I code classes. Not as many, of course, but they are a definite weapon in my quiver. A big reason for that is that I could code using Struts taglib code as a learning and doing mechanism together. Blah, blah, blah. This is not meant to be particularly profound. But I did want to give this boost to the tags in Struts. I think they have been very important to Java.

What do you think ?
Sure that could work (using Tiles or Sitemesh), but I'm not sure you
gain that much by having a tile/include contain a header htm:form
action=${ControlBean.the_action_URI}/ on it versus html:form
action=${myFormBean.the_action_URI}/. I probably wouldn't make a
whole seperate tile just for the html:form header.
Most of the time I don't need to dynamically change the action name
since the reusable form usually always has the same validation rules (an
update versus and add for me usually has the same data on the page..
sometimes hidden though). I also find it easier to understand when you
can quickly look at the JSP and see the action name delcared in the form
element.
Since I'm now leaning towards manually calling the validate methods
anyway (to avoid those issues of having to repopulate lists when
validation fails), I can always create custom validation calls based on
whether I'm doing an update versus an insert if I need to. This why the
Action name always remains the same on the form.
Obviously many ways to skin a cat here. I tend to avoid having dynamic
action names since some time a year later someone will say When I'm on
such and such a page and click submit, I'm getting this wierd error. To
track down the problem it's easy then to just look at the JSP and see
the action it's submitting to. When it's dynamic it's a bit more of a
pain to track down what is going on.

Craig if you have any comments regarding below I'd be interested in forwarding on to my co-worker here as well. Thanks. == This very topic has given me plenty of headaches. Only by diving into the Tomcat code did I start to figure out what was going on. The issue is that the login must happen in two places since both JBoss and Tomcat security were designed to work standalone. JBoss accomplished the integration of the two by hacking Tomcat to use JBossSX as a security realm while allowing Tomcat to continue collecting its own login credentials. When you performed your JAAS login within your action, you only authenticated yourself with JBoss. Since doing so bypassed the aformentioned hack, Tomcat never authenticated and the user principal was never applied to the session. I had a very similar issue not too long ago and when I finally figured out how JBoss/Tomcat integrated, my brain started spinning trying to figure out how to do a more intelligent form login through the JBoss/Tomcat stack. Fortunately form authentication wasn't a requirement for the immediate problem so I didn't put too many cycles on that problem. The moral of the story is that you can't bypass j_security_check without cutting Tomcat out of the authentication loop. You can't proxy j_security_check either. I tried some VERY creative hacks that way and none of them worked. Tomcat was designed specifically to not allow it. Too many potential exploits there. There is a possible solution if you're willing to apply a little elbow grease and bend the JAAS spec a little. Download the Tomcat source and take a look at org.apache.catalina.authenticator.BasicAuthenticator. That's a good reference for how Tomcat authentication works. Now take a look at the FormAuthenticator in the same package. This one is a bit more complex in that it saves the initial request so that it can replay it once authentication is complete. It is conceivable that you can write a StrutsFormAuthenticator that forwards to the ActionServlet to collect the credentials. Once you have your new authenticator, you can register it by adding it to org/apache/catalina/startup/Authenticators.properties with a key like STRUTS. Now go back to your web.xml and replace FORM with STRUTS and next time Tomcat deploys your war it should load up with your custom authenticator. Be aware that JBossWeb has its own shadows of Tomcat authenticators (the aformentioned hacks). Instead of extending Tomcat classes directly, you must extend these and you must patch the org/jboss/web/tomcat/tc4/Authenticators.properties file in deploy/jbossweb-tomcat41.sar/tomcat41-service.jar with your STRUTS reference.

nested tags and bean population

This renders just fine. The problem is that when a user edits each step and submits the form, only the stesp for the first Category get updated. The rest remain unchanged. I need for the user to be able to edit everything and then submit the form and have the edits be reflected in this nested relationship. Thanks in advance - Do you Yahoo!?

Subject: RE: some best practices questions
People seem to treat using the session as though it were some
kind of moral
sin.
There are technical pros and cons to using the session and
these should be
considered when you do your coding, but the session scope is
not harem. You
wont be cursed with eternal damnation because you shove a
couple of dropdown
lists in the session for a while. It just has implications for
performance/scalabilty in certain situations that mean that
avoiding its use
is often advantageous. (Such as the posibilty that a while
could translate
to until the session times out, and that if your in a clustered
environment the container may need to serialise the session
around between
machines quite often)
Usually those considerations are due to the fears that the
host machine or application will crash with a very high
volume of simultaneous users.
For example it is not a good idea to store large bitmapped
images, say from a 5.0mega pixel digital camera in a HttpSession
directly or indirectly for each web user. You are asking for
trouble if you suddenly architect a load balancing solution.
Doing 'wierd stuff' (tm) in application scope or on the file
system in an
effort to reproduce the effect of a session seems a bit dodgy
to me (ie:
surely the container is far better at implementing sessions
than you are!).
Now if its because you have thought it through carefully and
logically and
that in this case it really is better to do it this way then thats a
different matter, but if its just due to some instinctive ideological
aversion to using the session api, well thats just nuts.
Having said that you probably want to use a generic caching solution,
basically any lease-time based cache that uses a map collection
behind the scenes to cache images in my digital photostore example.
You would put a global image cache in the application scope (Servlet Scope)
and then all of the web application can access the cache.
Also you would set an expiration time to be greater than 30 minutes or
higher than the session timeout, or what is the point
I can see a place for lease time cache (LRU or otherwise) that sits
between the HttpSession (30 mins by default) and the application scope
(infinite or until the web container / server is restarted or die)
For this particular use case I would either just use the session, or
alternatively I would just look up the dropdowns from db each time and
accept the performance hit, but its (probably) not worth the
development
time - including ongoing maintenance - to do anything overly
tricky just for
a few dropdowns.
Alternatively behind the scenes put the cache in the DAO layer or
services layer. You can also rely on the OR/M framework to do this
for you if it is intelligent to cache similar queries and result
sets.

Subject: Re: some best practices questions
I have an idea how to persist the data that I currently place
in session
scope but I need to run it by someone.
Recall when I said that placing data in session scope is
frowned upon by
some members of my team? Well no one said anything about not
using Java
serialization. Why couldn't I serialize the
same data that I currently keep in session scope? I've already
implemented a solution for streaming images so creating a temp file
should not be a problem. Here is what I think I will need:
In the action where the data is first retrieved:
try {
final String prefix = myVehicleLineMap;
final String suffix = null;
File file = File.createTempFile(prefix, suffix);
FileOutputStream fileOutputStream = new FileOutputStream(file);
ObjectOutputStream objectOutputStream = new
ObjectOutputStream(fileOutputStream);
objectOutputStream.writeObject(myMap);
objectOutputStream.flush();
myForm.setTempFileName(file.getAbsolutePath());
} catch (Exception e) {
System.out.println(this.getClass().getName() + == +
e.toString());
}
In the action where the data needs to be re-accessed to
prepare the page
for re-display:
try {
FileInputStream fileInputStream = new
FileInputStream(myForm.getTempFileName());
ObjectInputStream objectInputStream = new
ObjectInputStream(fileInputStream);
SortedMap myMap = (SortedMap) objectInputStream.readObject();
// use myMap as before (when in session scope)
} catch (Exception e) {

Using nested:errors within other nested tags
Hi all,
would someone be able to tell me the correct way to do this, taking
advantage of the nesting?
I expected that after adding errors with the same nested property names as
the nested tags use (eg, person[0].username), it might be something like:
nested:form ...
...
nested:nest property=person[0]
tdUser name:/td
tdnested:text property=username / nested:errors
property=username //td
/nested:nest
...
/nested:form
and the nested property for the errors tag would use the same nesting as
the other nested tags (ie, person[0] in this case), but not so, at least
in my version of Struts, circa 1.1.
I have it working like this now, with a few changes to NestedPropertyHelper
(see below), but I can't help thinking I've missed the point.
Thanks in advance,
Maurice

Re: [OT] JBoss, Jaas and Struts
The helpfulness of people on this list continues to amaze me. Glad to know I'm not the only one struggling with this! I will play with the technique described when I get a chance, and I will let everyone know how it goes. But that may be next weekend. Meanwhile, I will post this general solicitation for advice to the list: I have a couple different Servlet-based apps that will be deployed on JBoss and/or Tomcat. Both will be exposed to the Internet, and both will require SSL -- at least server authentication and encryption of credentials (for sure), if not encryption of all content (maybe) and even SSL client authentication (probably not). On one, I will get full access to the Server box (we are planning to use JBoss 3.2.4). But, unfortunately, they are going to have Windows running on the box (ack). Had it been a unix box, my plan would have been to put an Apache in front of the JBoss server and to try to configure all the SSL stuff via Apache, because I know that is commonly done and I know it would be easy to get help doing it. But, if that doesn't work out, is IIS-Tomcat or IIS-JBoss/Tomcat a viable option, securitywise? Or how about JBoss/Tomcat alone? For the other, we will probably use a hosting company such as webappcabaret. They run Tomcat and promise full SSL support. The main question I have is, are there best practices I can follow within the scope of my Struts/Servlet-related programming that will make it easier to upgrade the security of these apps, or does it really matter that much exactly how access to resources is controlled (within this scope I mean)? Typically I find myself in the same environment -- authentication/authorization data is stored via RDBMS, an app-specific login is programmed for authentication, and the Servlet-related processors check User.Permissions objects stored as HttpSession attributes for authorization. Thanks again, Erik Rick Reumann wrote: Erik Weber wrote: Dang I thought I was onto something! I guess I'll stick to my User object in each session, and just try to make sure I centralize the auth checks as much as I can. Dunno why I ever wanted to change it, anyway. Thanks Craig for your time. I also sent your question on to a co-worker and he had this to say... Craig if you have any comments regarding below I'd be interested in forwarding on to my co-worker here as well. Thanks. == This very topic has given me plenty of headaches. Only by diving into the Tomcat code did I start to figure out what was going on. The issue is that the login must happen in two places since both JBoss and Tomcat security were designed to work standalone. JBoss accomplished the integration of the two by hacking Tomcat to use JBossSX as a security realm while allowing Tomcat to continue collecting its own login credentials. When you performed your JAAS login within your action, you only authenticated yourself with JBoss. Since doing so bypassed the aformentioned hack, Tomcat never authenticated and the user principal was never applied to the session. I had a very similar issue not too long ago and when I finally figured out how JBoss/Tomcat integrated, my brain started spinning trying to figure out how to do a more intelligent form login through the JBoss/Tomcat stack. Fortunately form authentication wasn't a requirement for the immediate problem so I didn't put too many cycles on that problem. The moral of the story is that you can't bypass j_security_check without cutting Tomcat out of the authentication loop. You can't proxy j_security_check either. I tried some VERY creative hacks that way and none of them worked. Tomcat was designed specifically to not allow it. Too many potential exploits there. There is a possible solution if you're willing to apply a little elbow grease and bend the JAAS spec a little. Download the Tomcat source and take a look at org.apache.catalina.authenticator.BasicAuthenticator. That's a good reference for how Tomcat authentication works. Now take a look at the FormAuthenticator in the same package. This one is a bit more complex in that it saves the initial request so that it can replay it once authentication is complete. It is conceivable that you can write a StrutsFormAuthenticator that forwards to the ActionServlet to collect the credentials. Once you have your new authenticator, you can register it by adding it to org/apache/catalina/startup/Authenticators.properties with a key like STRUTS. Now go back to your web.xml and replace FORM with STRUTS and next time Tomcat deploys your war it should load up with your custom authenticator. Be aware that JBossWeb has its own shadows of Tomcat authenticators (the aformentioned hacks). Instead of extending Tomcat classes directly, you must extend these and you must patch the org/jboss/web/tomcat/tc4/Authenticators.properties file in deploy/jbossweb-tomcat41.sar/tomcat41-service.jar with your STRUTS reference.

Re: JSF vs Struts - Development Process Questions
I have some questions regarding the development process when using JSF, especially in realtion to HTML designers. Will everyone on the team need the same advanced design tools? Will the designers who are used to tweaking HTML/JSP be restricted to a completely visual drag and drop environment? Or even worse, will the HTML designers be required to learn JSF mark up code? There was another thread a few weeks ago relating to the general development process. Like many others, we have gotten used to the process where the HTML designers mock up a page and then a software engineer transition the page to a JSP and wires it into our system (using Struts, and JSTL). What is the vision for the development process in JSF? Also, what is the ultimate vision for JSF? Do you invision a IDE that can create interfaces on the same level as Flash? A question asked earlier in this thread: Will JSF integrate with Flash forms? It would be cool to have one integrated development system that could do it all. This thread was started with the question, If you were starting a project today, what would you use, Struts or JSF? My answer is, I would use Struts with JSTL and I would purchase the new Eclipse based IDE, NitroX (http://www.m7.com/). We purchased licenses for NitroX after our CTO came back from JavaOne. It looks like the creative people at M7 have done a lot of things right; they even have planned support for JSF. NitroX may very well evolve into the IDE that can do it all. The best thing about NitroX is that it will enable a transition from Struts to JSF if you decide to go that route. The main reason I would choose Struts/JSTL over JSF is that it works well within the existing skill sets of most developers and designers. I would keep an open mind regarding JSF, especially in regard to high level components that are not easily created using JSP/JSTL. This is the area where JSF could win the game. In the near term, my guess is that the really cool advanced interfaces are going to require Flash.

Craig McClanahan (Original creator of the Struts framework) As an original historical matter, it would be hubris of the highest variety to question you on this, Craig. As a historical consequence, however, I for one think that this turned out to be the more revolutionary result of struts, leading coding into taglibs in a way not seen before. The controller and MVC (of sorts) pattern in Struts existed in all sorts of forms prior to Struts. Struts did it better than most, maybe better than all the rest, and provided a standard that people could code to. But, those tags were just a big surprise in the way they hit the market. I, for one, now code tags as readily as I code classes. Not as many, of course, but they are a definite weapon in my quiver. A big reason for that is that I could code using Struts taglib code as a learning and doing mechanism together. Blah, blah, blah. This is not meant to be particularly profound. But I did want to give this boost to the tags in Struts. I think they have been very important to Java.

Hi Erik, Not too long ago I struggled with this issue too and also played with the SecurityFilter (on sourceforge.net) but it didn't work with JBoss. And so after digging and digging I came up with my own security filter that Does work with JBoss and in fact can be adapted to more Application server. Though it is not as fancy in terms of configuration, it is sure working for me and since then I have no headaches - at least not from that direction :) If you are interested in the code, send me an email.

Glad to know I'm not the only one struggling with this! I will play with the technique described when I get a chance, and I will let everyone know how it goes. But that may be next weekend. Meanwhile, I will post this general solicitation for advice to the list: I have a couple different Servlet-based apps that will be deployed on JBoss and/or Tomcat. Both will be exposed to the Internet, and both will require SSL -- at least server authentication and encryption of credentials (for sure), if not encryption of all content (maybe) and even SSL client authentication (probably not). On one, I will get full access to the Server box (we are planning to use JBoss 3.2.4). But, unfortunately, they are going to have Windows running on the box (ack). Had it been a unix box, my plan would have been to put an Apache in front of the JBoss server and to try to configure all the SSL stuff via Apache, because I know that is commonly done and I know it would be easy to get help doing it. But, if that doesn't work out, is IIS-Tomcat or IIS-JBoss/Tomcat a viable option, securitywise? Or how about JBoss/Tomcat alone? For the other, we will probably use a hosting company such as webappcabaret. They run Tomcat and promise full SSL support. The main question I have is, are there best practices I can follow within the scope of my Struts/Servlet-related programming that will make it easier to upgrade the security of these apps, or does it really matter that much exactly how access to resources is controlled (within this scope I mean)? Typically I find myself in the same environment -- authentication/authorization data is stored via RDBMS, an app-specific login is programmed for authentication, and the Servlet-related processors check User.Permissions objects stored as HttpSession attributes for authorization. Thanks again, Erik Rick Reumann wrote: Erik Weber wrote: Dang I thought I was onto something! I guess I'll stick to my User object in each session, and just try to make sure I centralize the auth checks as much as I can. Dunno why I ever wanted to change it, anyway. Thanks Craig for your time. I also sent your question on to a co-worker and he had this to say... Craig if you have any comments regarding below I'd be interested in forwarding on to my co-worker here as well. Thanks. == This very topic has given me plenty of headaches. Only by diving into the Tomcat code did I start to figure out what was going on. The issue is that the login must happen in two places since both JBoss and Tomcat security were designed to work standalone. JBoss accomplished the integration of the two by hacking Tomcat to use JBossSX as a security realm while allowing Tomcat to continue collecting its own login credentials. When you performed your JAAS login within your action, you only authenticated yourself with JBoss. Since doing so bypassed the aformentioned hack, Tomcat never authenticated and the user principal was never applied to the session. I had a very similar issue not too long ago and when I finally figured out how JBoss/Tomcat integrated, my brain started spinning trying to figure out how to do a more intelligent form login through the JBoss/Tomcat stack. Fortunately form authentication wasn't a requirement for the immediate problem so I didn't put too many cycles on that problem. The moral of the story is that you can't bypass j_security_check without cutting Tomcat out of the authentication loop. You can't proxy j_security_check either. I tried some VERY creative hacks that way and none of them worked. Tomcat was designed specifically to not allow it. Too many potential exploits there. There is a possible solution if you're willing to apply a little elbow grease and bend the JAAS spec a little. Download the Tomcat source and take a look at org.apache.catalina.authenticator.BasicAuthenticator. That's a good reference for how Tomcat authentication works. Now take a look at the FormAuthenticator in the same package. This one is a bit more complex in that it saves the initial request so that it can replay it once authentication is

This thread was started with the question, If you were starting a project today, what would you use, Struts or JSF? My answer is, I would use Struts with JSTL and I would purchase the new Eclipse based IDE, NitroX (http://www.m7.com/). We purchased licenses for NitroX after our CTO came back from JavaOne. It looks like the creative people at M7 have done a lot of things right; they even have planned support for JSF. NitroX may very well evolve into the IDE that can do it all. The best thing about NitroX is that it will enable a transition from Struts to JSF if you decide to go that route. The main reason I would choose Struts/JSTL over JSF is that it works well within the existing skill sets of most developers and designers. I would keep an open mind regarding JSF, especially in regard to high level components that are not easily created using JSP/JSTL. This is the area where JSF could win the game.

Craig McClanahan (Original creator of the Struts framework) As an original historical matter, it would be hubris of the highest variety to question you on this, Craig. As a historical consequence, however, I for one think that this turned out to be the more revolutionary result of struts, leading coding into taglibs in a way not seen before. The controller and MVC (of sorts) pattern in Struts existed in all sorts of forms prior to Struts. Struts did it better than most, maybe better than all the rest, and provided a standard that people could code to. But, those tags were just a big surprise in the way they hit the market. I, for one, now code tags as readily as I code classes. Not as many, of course, but they are a definite weapon in my quiver. A big reason for that is that I could code using Struts taglib code as a learning and doing mechanism together. Blah, blah, blah. This is not meant to be particularly profound. But I did want to give this boost to the tags in Struts. I think they have been very important to Java.

I recall reading about a month ago that setting up of data-sources in struts-config was purely for some backwards-compatability issue, and was no longer advised. I haven't bothered to do it. I set up my data source in a server.xml context, and it works fine. Like you I'd prefer to have server-wide scope on the data-source rather than context scope, but I haven't spent any time on it yet. One option may be to configure the data-source as part of the DefaultContext.

If the datasource is setup in struts-config.xml, the scope becomes struts only and is specific to only one webapp, and it can't be retrieved by JNDI. So I can setup datasource in both ways, setup in server.xml has much more flexibilty and benifit from JNDI, why do I need to setup in struts-config.xml?? once again, thanks, ^^ Regards - 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]
Re: Datasource problem again..
Thx ! Since I am using Tomct 5 with auto-depoly, my Webapp DOESN'T has a Context element in server.xml. I think I will has a try to setup in default-context, or should I manually all a context element of my Webapp in server.xml??

Re: Datasource problem again..
If you're auto-deploying and can get the DefaultContext to work for you, then that's what I'd do. (I'm not auto-deploying, so my case isn't so straight-forward). You always have the fall-back of configuring Context datasources if you run into trouble. There's an example of configuring a DefaultContext with a datasource here: http://jakarta.apache.org/tomcat/tomcat-4.1-doc/config/defaultcontext.html This is how I've configured my data-source: Context docBase=/webapps/isurvey path=/isurvey reloadable=true Resource name=jdbc/as400 auth=Container type=javax.sql.DataSource/ ResourceParams name=jdbc/as400 parameter namemaxWait/name value5000/value /parameter parameter namemaxActive/name value4/value /parameter parameter namepassword/name value**/value /parameter parameter nameurl/name valuejdbc:as400://localhost;naming=system/value /parameter parameter namedriverClassName/name valuecom.ibm.as400.access.AS400JDBCDriver/value /parameter parameter namemaxIdle/name value2/value /parameter parameter nameusername/name value**/value /parameter /ResourceParams /Context And this is how I use the data-source in java: Context ctx = new InitialContext(); Context envCtx = (Context) ctx.lookup(java:comp/env); DataSource ds = (DataSource) envCtx.lookup(jdbc/as400); I'd be interested to know how you get on with this.

Re: Datasource problem again..
You can still have a context regardless of whether you auto deploy or not. See that snippet that jthopmson sent? You can deploy that with your war file, I think the name of the xml has to match the war file name if I'm not mistaken. Then you will have a context properly setup with the datasource.

Logic Iterate tag
Hi All, I am currently using for loops and iterators for traversing arrays and coolections in JSP. I am planning to use this logic : iterate tag in place of this. I need to know if there is any advantage of using this tag in terms of performance or reduction in Java code in JSP etc. Thanks and Regards Aditya
