Thanks Antonio.

Yes, this is exactly what I want.

And this is my fourth day to learn about JSP, STRUTS and everything about JAVA. So I found there are too much to learn, whereas I don't have much time to learn it systematically and I don't have enough materials to learn it from espesially that I cannot access Internet except e-mail. So this mail list is the only way that I can ask my questions.

I suppose that you are writing about <bean:write>.
Well, you can do it by using:
<bean:write name="formBeanName" property="test" />
"formBeanName" is the name that you declared in your
struts-config.xml, along with the called action.
The "getTest" will get called.

P.S.: It seemed too simple to be true. Is it really this what you want?

Hi all, I'm trying to make a password field be at least 6 characters in
length but the check doesn't seem to work.
Here's my code:
  /**
  * @struts.validator type="required,minlength,maxlength,mask"
  *
  * @struts.validator-var name="minlength" value="5"
  * @struts.validator-var name="maxlength" value="20"
  * @struts.validator-var name="mask" value="^[a-zA-Z_0-9-]*$"
  *
  * @struts.validator-args arg0resource="prompt.password"
  * @struts.validator-args arg1value="${var:minlength}"
  * @struts.validator-args arg2value="${var:maxlength}"
  *
  * @param password The password to set.
  */
 
  public void setPassword(String password) {
       this.password = password;
  }

Any ideas? Thanks

First of all, I'm not even sure if it's possible to use the portlet
and the jsf plugin at the same time. I have not tried, but there might
be issues with it if they try to do conflicting things in the
interceptors and the results.

A couple of things here. You're extending portlet-jsf-default, which
still has the jsfStack as the default interceptor ref. Since you have
defined a "jsf" package that extends "portlet-jsf-default", you should
probably extend the "jsf" package instead. However, it's probably just
as easy configuring the correct interceptor stack and default
interceptor ref right there in the "portlet-jsf-default" package. In
addition, you're overriding the default interceptor stack in your
action definition, so it's not really using the portletDefaultStack,
even if you had configured your default interceptor stack correctly.
Unless you need to use different interceptors in your action, there's
no need configuring those interceptor-refs there.

You could also try swapping the order of the portletDefaultStack and
the jsfStack and see if that makes a difference.

Maybe that's the problem, FileUploadInterceptor check if action
implements it and add error messages. If you implement it, remember to
add result name=input.

What I need is to have one action and many various (POJO) objects, which
polulate and receive date from html form. POJO object should be selected by
the form, which is displayed (or submited). But I realy don't know how to do
this in Struts 2.

Hi, all.

I'm working on a form that would allow some arbitrary number of
documents to be uploaded at once. The idea is that by default, one set
of document fields appears, and there's a link that a user can click to
activate some javascript that would add another set of document fields.
I have this basically working. The new fields are named the same as the
old fields, and that works just fine, with Struts automatically making
those into array properties.

My question, though, is how to make it not look horrible. I've included
the JSP below, and as you can see, I have an invisible div that I clone
and insert into the DOM tree before the Submit button. What I want is
for the cloned portion to be added as additional table rows in the table
that Struts creates for the main form. Instead, the cloned portion ends
in a table inside of a single cell in the original form's table. How can
I write the JSP so that the cloned portion fits in nicely? Is this a job
for a new theme? Have I just taken the complete wrong approach?

Thanks,
Dan Allen

Yes, create a custom theme to get out of that table. css_xhtml may work
immediately.

Potential issues:
- Your current approach is also going to create nodes with duplicate
ids. This may confuse some browsers badly. At least remove the ID from
the template
- I'm not sure that order is guaranteed when you have two params with
the same name at time they are submitted. Ensure you can't get a
mismatch between doctype/doc name when uploading multuple files. ie.
doctype[1] is associated with docname[0]. It seems vulnerable to
browser-dependent processing of the form.

You may be safer generating the DOM nodes with JS programmatically
rather than doing a clone. That way you'll be able to assign unique
ID's for each node, add listeners for validation and use array notation
in your field names to guarantee order for struts eg. "doctype[1]".

hope that helps,

Hi all

Creating my first struts2 web application i came to the point where
questions about access restriction and authentication pop up.

I read some articles about these topics that cover certain single aspects
but none of them seem to answer all my questions.

As far as i learned, i think best way to implement authentication for
Actions is to implement a Interceptor which filters out requests and
redirect them to the login page as long as the requesting client was not
authenticated. And upon login i would store a param in the session which i
will look up in the Authentication Interceptor to find out if the client
already did authenticate.
Is that a good practise? Or are there better ways to do authentication? Any
special things to think about? I.e. what about session hijacking? Should i
also store the ip where the authentication credentials were sent from
initilally and check this ip against the ips of subsequent request related
to the same session?

So i implemented a simple AuthenticationInterceptor and deployed it. That
works so far, but only for requests to Actions. When requesting a jsp file
directly by url from the browser the jsp is delivered by tomcat. I don't
like to have users being able to directly access jsp without authentication.
Basically i thought that requests for jsp also would be passed to the
AuthenticationInterceptor (as far as i understand, an interceptor is
basically a servlet filter) so the same authentication checks would apply as
for Actions (servlets, and as far as i understand, jsps are also a kind of
servlets, so why should that be handled differently?). But this obv. Doesn't
work.
I found some articles that put a piece of code in each jsp, checking if a
kind of "logged-in" param is set in the session and does a redirect to a
login page if that isn't the case. To be honest, i don't like that method, i
wouldn't like to have such a statement on every jsp. I think there must be a
better, smarter way to do that.

I just read bout about Acegi (http://www.acegisecurity.org/). As far as i
understand this framework would provide mechanisms for authentication and
authorization (which also will be going to be a topic in a later project
stage). In its documentation i read that it's working with spring. Does this
only refere to Spring für DI, so i would be able to use Acegi also for
authentication in my Struts2 application (which already uses Spring for DI)
or does it only work with Spring Actions?

I'm very thankful for any tips and tricks or references for further reading.


Thanks a lot & regards
Frank

It works very well with Struts2 or with any other web framework, even
there is some example how to develop Struts2 Interceptor in inject
Auth context to an action.

Isn't it the case that Struts2 integrates Dojo, but a version older than
the latest Dojo version? Should I expect any difficulties if I try to
use the latest Dojo in a Struts2 application? I imagine this might
preclude trying to use the Struts2 tags that use Dojo widgets (or just
need some additional config steps), so I guess I'd need to understand
the impact of that.

I also see that Dojo uses "${...}" references for variable substitution.
Will that cause problems if this code is in a JSP?

Yes.

Not if you're not trying to combine the two versions; you can use "naked"
Dojo in an S2 app just like you would in any other framework.

I'm not sure what you mean there; do you have a link to what you're referring
to?

Dave

The following link into the "Dojo Book" has an example. There are
others throughout the book. The "${...}" is substituted on the CLIENT
side.

Oh, the templates? Yeah, if you tried to use that notation on a JSP page it
would cause a problem. I'd imagine escaping the $ would work, although I
haven't tried it.
