That will sort whatever is inside of lActions base on the anonymous

I think there was an implicit assumption in the sentence you quoted, that
you were using BeanUtils or PropertyUtils to manipulate the properties.
If your code had actually been:

  String username = PropertyUtils.getProperty(form, "username");
  String password = PropertyUtils.getProperty(form, "password");

then you would indeed have had to make no changes when you swtiched from a
standard ActionForm bean to a DynaActionForm.  If you're planning on
experimenting with such switching, you might want to think about coding
defensively like this.

Nope, one of the differences between DynaForms and conventional forms is
that Dynaforms are map-based, which means you need to rewrite those
lines as:

String username =  (String)((LoginForm)form).get("username");
String password = (String) ((LoginForm)form).get("password");

I got so sick of recasting to String that I wrote my own class which
extends DynaActionForm class and has getString helper methods in it.

DynaActionForm question

[Mark Minnie]

"Struts in Action" on page 162 reads:

"You can use a DynaActionForm anywhere an ActionForm can be used.  You can also 
substitute a DynaActionForm for a conventional ActionForm without changing any of the 
existing Java or JSP code."

I changed a ActionForm to a DynaActionForm by using the struts-config.xml:


   
   


I thought I would not have to change my existing code in the Action java code, but my 
existing code did not work.  I originally had:

String username = ((LoginForm)form).getUsername();
String password = ((LoginForm)form).getPassword();

The LoginForm was the form bean that I had created manually in java.  I deleted the 
LoginForm and replaced the form bean with a DynaActionForm as listed above.  Of 
course, once I no longer have a LoginForm.java file because it is a DynaActionForm, 
this Action java code does not compile. 

Therefore I see that I have to change my code in going from a manually coded form bean 
to a DynaActionForm.  

Am I missing something?

TIA

But, I get the feeling that you want the action to forward to one of

One might be in 'p3/layout' and another in 'p4/layout'?

If this is the case, then the only way I can guarantee that you will

Geoff,
Thanks for your answer.
The problem is '/layout' or another directory gets appended there by
Tomcat at runtime..Here's the whole story:
The content is generated by a content editor, and for internal links we
specified that the client uses the following format:
Some link text here

When this content is loaded, and it's loaded by a Tiles layout jsp,
Tomcat automatically reads it as :
http://hostname:port/ppp/p3/layout/link.do?urn=1334333
where 'ppp' is the name of the context and 'p3/layout' the path to the
directory where the Tiles layout jsp resides.

And I'm trying to get my web app to forward all 'link.do' requests to
the same handler.

I don't want to hardcode the directory structure into the struts-config
when defining the  element...

It sounds as if this is an action used in multiple context's, and if
you
don't want to make
multiple mapping's, then why not just have the one mapping that is 
used
everywhere.

The path in a mapping is just the name of the action on the server. It
doesn't relate back to a
directory structure, although, a path can be made to look that way.

Hi there,

I just wanted to see if there's anyone here who has succesfully deployed a

I am using Tomcat for development, but need to be able to deploy on
websphere?

As yet I have had no luck.

I am using

Struts 1.1Beta-1
Eclipse
am making the war file using Eclipse, the war file works with tomcat, but
not websphere.

Websphere pickup my welcome page, it then calls findefault.do, but that

I think there must be some added setting one of my xml files needs.

Can anyone help me out

(getting it from database) so decided to use map-backed ActionForm. I also 
need to show the existing state (in database) in the web form and then allow 
user to change it. I am not sure how to prepopulate the map and write the 
jsp so that



shows what's their in database and allows the user to change it.

Sample code wil be highly appreciated.

Thanks
Rajiv

How to use struts to handle session id in the following DHTML menu?

[Jason Yam]

Hi everyone,
 
anyone know how to change the following DHTML statement using in one
struts project so that struts will use the same jsessionid for all the DHTML
menu links?  For example, it will append jsessionid when the cookie function
is disabled and it will use jsessionid invisibly when the cookie function is
enabled.

Edit

 
I try to change the above statement using  so
that struts will take action on it and it works.  However, it looks a little
bit ugly.  Here is the way I modify:
 

Inquiry

 
and it will generate the following DHTML statement:

Anybody knows how to modify?  Is it feasible in the struts 1.0 release?
Is it feasible in the struts 1.1 release?
 
Thank you

RE: Using internationalised messages as custom tag parameters

[Marco Tedone]

Have you tried with the following?

MessageResources resources =
(MessageResources)request.getAttribute(xxx.MESSAGES_KEY);

Then the resources.getMessage("xxx") shall return you the value.

Hope it will works :-)

Subject: Using internationalised messages as custom tag parameters



When using custom tags, sometimes I want to pass an internationalised string
as an attribute value: e.g. using the display:column tag inside
display:table, I want to specify the column title using the message resource
key and not a constant string.

Currently I have it working using the very ugly code (cut down and
simplified):

...
<% org.apache.struts.util.PropertyMessageResources msgs = 
 
((org.apache.struts.util.PropertyMessageResources)request.getAttribute(org.a
pache.struts.Globals.MESSAGES_KEY) ; %>

...

   
 

Ideally I would like to be able to set this attribute using the bean:message
tag, but I don't see any way to do so.

I would also like to be able to easily apply text filtering for html
sensitive characters as per bean:write

Is there a cleaner, neater way to do all this?

Re: struts servlet-mapping

[geoff]

Cagan,

using the  tag will solve your action calling problems:
Some link text here

this will produce the following link:
Some link text here
use the paramId, paramName, paramProperty attributes if the 'urn' value is 
dynamic.


But, I get the feeling that you want the action to forward to one of many 
tiles layout jsp's.
One might be in 'p3/layout' and another in 'p4/layout'?

If this is the case, then the only way I can guarantee that you will 
achieve this is to pass the value
'p3/layout' as a parameter and then pre-append it to your action's 
forward.

I'm not saying that this is the only way, but it is the only one that I 
don't have to test to know that it will work :)

Geoff,
Thanks for your answer.
The problem is '/layout' or another directory gets appended there by 
Tomcat at runtime..Here's the whole story:
The content is generated by a content editor, and for internal links we 
specified that the client uses the following format:
Some link text here

When this content is loaded, and it's loaded by a Tiles layout jsp, 
Tomcat automatically reads it as :
http://hostname:port/ppp/p3/layout/link.do?urn=1334333
where 'ppp' is the name of the context and 'p3/layout' the path to the 
directory where the Tiles layout jsp resides.

And I'm trying to get my web app to forward all 'link.do' requests to 
the same handler.

I don't want to hardcode the directory structure into the struts-config 
when defining the  element...

I agree. But I think support of wildcards in the path would be very

It sounds as if this is an action used in multiple context's, and if

The path in a mapping is just the name of the action on the server. It

A primary reason is that there can be more than one RequestProcessor in a
struts based application -- indeed, there will be one per module.

The second reason is that getRequestProcessor() in Struts is actually a
factory method -- it will create the instance if it's not there alrady,
and save it (as a servlet context attribute).  In order to avoid race
conditions where two threads both discover that the RequestProcessor
doesn't exist and both create a new one.

There's a similar situation inside the standard RequestProcessor itself,
where the processActionCreate() method creates new Action instances if
they don't exist already.  The only difference is that synchronized block
is inside the method (because not everythng there needed to be
synchronized).

> Could the synchronized method be a bottleneck
> in the Struts framework?.

Most likely not.  Especially on a 1.4 platform, synchs are pretty fast,
and there's probably hundreds of them executed every request anyway
between what your app does, what your JDBC driver does, what Struts does,
and what your servlet container does.

Yes, it is -- it's required to live up to the contract that the request
processor for a particular module is guaranteed to be a singleton.

Could you use something like OS Cache tags to cache the individual
tiles that don't change.  I've been using it and it is working
well for me.  Very simple.

See http://www.opensymphony.com:8668/space/OSCache

Please don't get me wrong I'm a big fan/advocate of struts and wasn't trying
to say it was Strut's fault.
I was merely trying to submit a patch; and avoid hours of frustration for
the people that use resin/ struts

If it works on platform and not the other , we all might as well be
developing Microsoft applications.

RE: RequestProcessor

[Marco Tedone]

I think because probally, as in the Struts framework only a single instance
of an Action is created for each application, and the RequestProcessor is
called by the ActionServlet istance, the synchronization ensure the
integrity between ActionServlet and RequestProcessor instances.

Subject: RequestProcessor


Hello,

I found out a little (but important) difference in the use of the
RequestProcessor between the Sun WAF (Petstore application) and Struts. In
the Sun framework the method is not synchronized:

MainServlet.java (Sun WAF):

private RequestProcessor getRequestProcessor() {
...
}

but in the Struts Framework the method is synchronized:

ActionServlet.java (Struts):

protected synchronized RequestProcessor
getRequestProcessor(ApplicationConfig config) throws
ServletException { ... }

Why this design difference?. Could the synchronized method be a bottleneck
in the Struts framework?. Is it really necessary to the correct execution of
the struts actions?. Thanks,

Angel

Re: Struts / Tiles Design question

[Cagan Senturk]

I believe there is no way you can refresh part of a layout; the whole 
layout jsp will have to reload.
For your second question, you can write the menu part of your layout 
(say 'menu.jsp') in a way capable of recognizing the current section 
selection of the user and self-expand accordingly...

Re: Struts / Tiles Design question

[Christopher Willingham]

For your second question I believe the answer is to create a new tiles
definition where you override the menu tile.  In your action reference the
new definition.

But your first question I don't know.  I am now building my first large
corporate struts app and am using tiles which I like very much but am very
worried about speed and wonder whether I should use frames to speed things
up( for your re-gen reasons as well as the caching of images, javascript ref
tables, etc on a fixed frame such as navbar).  So I am curious how tiles
would run on top of frames and whether I should consider it.
