PageFlow within a Tile?!

Hi,

I am trying to write a webapp with struts and tiles that is similar to the portlet-technology. The tiles-documentation example provided with struts is very helpful to create the main functionality (e.g. customizing the portal by moving the tiles). But so far I haven`t figured out how to create a page flow within a tile. 
For example in the tiles-documentation I want to add a link in one of the tiles and when clicking that link another page should be rendered within the framework. How can I achieve that?

Thanks in advance!!

dom

PS: Does anybody know when STRUTS 2.0 is supposed to be released?

Re: Error Start Tag Exception

Posted by Niall Pemberton <ni...@blueyonder.co.uk>.
<html:errors> changed from processing ActionErrors/ActionError to
ActionMessages/ActionMessage from struts 1.1 to struts 1.2 - the most
obvious cause of this is your app generating ActionMessages/ActionMessage
messages but the tag is struts 1.1 version.

Are you sure you are deploying the nightly build jars to your servlet
container rather than the struts 1.1 jars?

Hi Betty,

I think you need to set the 'message' attribute to false here, as the tag is

looking for an ActionMessage instance, not an ActionError one (which is what
you 
get in the loop created by the <html:errors /> tag).

Here's a snippet of an implementation I've used:

<logic:messagesPresent message="false">
   <td class="small3" colspan="2">
     <html:messages id="error" message="false">
       <c:out value="${error}" escapeXml="false" /><br />
     </html:messages>
   </td>
</logic:messagesPresent>

HTH,

Hi All,

i have this form to upload a document to a folder on the server. i have a
field where you browse
the files on your computer to upload to the server. once that field is
chosen i would like another field to be populated automatically with only
the document's name, without the path extension on it. does anyone know how
to go about doing this?

RE: Session Validation

Posted by Andrew Hill <an...@gridnode.com>.
Main problem with CMA is that its configuration is container dependent. If
your writing an app that needs to be deployed straight to many different
containers CMA can be troublesome.
btw: if you are doing your own session based security - dont - put check
tags in the JSP. Follow Niall's suggestion and hide them under WEB-INF and
go through actions to get to them.
You can put security checks for the session object in a filter, or if under
servlet 2.2 you could override the request processor to do it.

If you only need to run on one particular appserver at any moment, then CMA
is the way to go unless your requirements are really wierd. Struts
ActionMappings support specifying roles required for actions, and (unless
you override the RP) this only works with CMA.

I'm not an expert on security but as I understand you have two choices. You
can either implement "container managed security" - where the servlet
container controls logging on and ensures that only authenticated users can
have access to the resources you specify OR you can control it yourself
within your application.

It sounds to me like your asking about the second. Typically when your
application controls security, you place something in the User's Session
when the user "logs on" to indicate that they have done so. Then in your
"Action" classes you check the session to see if they have logged on - if
not you forward them to the "logon" screen. If your jsp's are available you
also need to protect them - the struts sample used to have a tag (haven't
looked at it recently) which did the same kind of check. Alternatively you
could "hide" your jsps in the "WEB-INF" folder so that the user can't access
them directly and you don't need to do the jsp check.

The generally accepted view though is that it is better to choose the first
option - container managed security. If you use Tomcat, have a look at the
web.xml file for the Tomcat "admin" application (In Tomcat 4.1 its in the
\server\webapps\admin\WEB-INF folder). The admin app is actually a Struts
application. The <security-constraint>, <login-config> and <security-role>
sections are what controls container managed security for that app.

Hi,

I am sorry if this question have been asked before.
How can i check session validation? to check whether if the user is
authenticated on each page.
I read somewhere about Filters
but i still do not know how to implement it.

Currently I use a LoginAction to check the user details against the database
and then do the appropriate forwarding.
