RE: Struts and cocoon

I thought stxx doesn't support WML!
Do U mean that we can do it by writing our own output transformer/renderer 
sort of things??

Cocon to me is meant to replace Apache static content.
Struts is for dynamc content.
I strore XML content in DB (in basicPortal) and render it using JSTL X
transform tag.
If you read a bit about FOP, you can render anything.

Cocon I think is also semi-parked.

Dynamic!

RE: Struts and cocoon and stxx and wap / wml

Thanks for that Stefan!
I am gonna start on modifying the client side of my application (using 
stxx) from tomorrow itself :)
I really appreciate UR suggestions.

I had to check it make sure, but of course you can transform xml into

JAXP includes two implementations of XSLT, an interpreting version

versions of desired transformations as translets, for the most efficient
runtime processing later on.

Xalan-Java is an XSLT processor for transforming XML documents into
HTML, text, or other XML document types. It implements the W3C
Recommendations for XSL Transformations (XSLT) and the XML Path Language
(XPath). It can be used from the command line, in an applet or a
servlet, or as a module in other program.

And yes ... WAP is an xml document type (wap pages should(have to)
include a ref to a DTD) e.g. :

That's it .. no more cocoon!

Hi Stefan!


Actually I'm looking into this issue myself (new project that was
launched this morning). Will get back to you when I know what is
possible.


That would be really great, if U can give me some input about it.
Good luck with UR new project!

RE: Struts and cocoon

[Madhavi Thottempudi]

But, I see that the possible outputs supported by stxx are only html, pdf 
and svg.
Whereas cocoon also supports WML, RTF apart from HTML, PDF& SVG.
Isn't that an advantage of cocoon over stxx??

Struts and cocoon

[Madhavi Thottempudi]

Hi!
Is anybody out there working with Apache cocoon and Struts framework together??
We are building a struts application and one of our requirement is 
"Transformations".
I am quite interested to know if anybody has worked on this combination, as 
I am wondering if it's possible to do that at all.
Any comments/suggestions on this would be really helpful.

Cheers

RE: global variables-update

[Madhavi Thottempudi]

Hi Divakar!
Thanks for the suggestion.

I am still confused with one thing
In the example provided by struts (struts-example), I found that they are 
calling getServletContext from the Action bean to get a global/application 
scope attribute,
but I felt it strange as there is no servlet passed to the Action Bean.

The code is as follows:
public final class SaveRegistrationAction extends Action {

public ActionForward perform(ActionMapping mapping,
  ActionForm form,
  HttpServletRequest request,
  HttpServletResponse response)
 throws IOException, ServletException {

 // Extract attributes and parameters we will need
 Locale locale = getLocale(request);
 .
 ..
 Hashtable database = (Hashtable)
   servlet.getServletContext().getAttribute(Constants.DATABASE_KEY);
 if (servlet.getDebug() >= 1)
 servlet.log("SaveRegistrationAction:  Processing " + action +
 " action");
 
 .
}
}

Any idea where this servlet is coming from???

regards
-M

global variables

[Madhavi Thottempudi]

Hi!
Where can I set global variables and get them back in Struts. Because I see 
that Action beans extending struts Action bean doesn't get servlet in their 
perform method.

public ActionForward perform(ActionMapping mapping,
 ActionForm form,
 HttpServletRequest request,
 HttpServletResponse response)

Any suggestions???

Thanks
-M

Moving from MVC architecture to STRUTS

[Madhavi Thottempudi]

Hi there!
I am new to Struts technology and I have few doubts to clarify from U 
experienced people
I am considering to move our web-application which is now based on MVC 
architecture to Struts and as a first step I'm doing some research on it 
and got stuck with few things.

My doubts are -

1. From what I understood, at the Controller end - the Controller servlet 
and the mapping of the actions is provided by the framework.
But when I saw the example struts application, I got bit confused with the 
structure of struts - when it comes to session & entity beans.
In user guide it's mentioned that "the design is not good" or "considered a 
bug in the design" as business logic is embedded in actions - this 
statement implies I can have my entity beans as usual. But can I maintain 
some session scope beans too or is there any alternative structure in the 
Struts framework??? I mean is the design of session and entity beans left 
to us??

2. For the View - is there any functionality in struts to switch between 
different views depending upon what client (viewer) U have - desktop, Palm, 
mobile, etc

3. Can I use Access database at the back-end. I have seen few examples but 
they were using Mysql.

I really appreciate any suggestions or input. Thanks.

-Madhavi
