Re: Cocoon, sockets and not a web browser.

[Mauro Daniel Ardolino]

Hi! I've red all the information and mails.  Thanks a lot.
I think TRaX will be the best solution.  I'm not sure if I am missing
something (e.g. i18n), but for the moment it's my choice.

Now I think I will not use XSP logic because it can be solved with Java.
My applications will be using the same logic and transformations within
servlets and other java objects.  So...I do not have to use cocoon (as
Jacob said before).

Am I missing something?

Thanks,

Mauro

RE: Cocoon, sockets and not a web browser.

[JohnsBrn]

I think I may be doing something similar to what you want to do. I am calling cocoon 
from an axis provider, and also directly from within an ejb. There are several things 
you need to do to accomplish this: The first thing you should look at is the 
commandline context under org.apache.cocoon.environment. That will give you some clues 
on where to start with creating a non-servlet based cocoon application. I am also 
using cocoon from within a servlet context, so I took the easy way out and created a 
remote wrapper for cocoon to place in the JNDI naming context, but it still required 
me to write a custom Environment, Request, Response, etc... for my application 
context. You should be able to use the standard serializers and generators from 
cocoon. The output from cocoon will be captured in the output stream in your 
Environment class. The other option you have is to use the pipeline classes directly, 
but then you lose the ability to configure the pipeline using the cocoon/avalon 
framework. Hope that helps.

All right! But I warn you I'm new with this.

Yes.  I'm trying to do something like this.  Exactly!  Even more complicated,
but "thanking cocoon" for its services.  
May be some part of cocoon may be used without cocoon.  I mean that may
be we can "simply" use the transformation classes (generators,tranformers)
inside our java code, without needing a sitemap.  We can write the
pipelines like this:
  ...
  xmlFile= generatorX.generate("doc/anXmlFile.xml","file");
  xmlFile= transformerY.transform(xmlFile,"style/anXslStylesheet.xsl");
  xmlFile= transformerZ.transform(xmlFile,"style/otherXslStylesheet.xsl");
  ...

Re: Cocoon, sockets and not a web browser.

[Mauro Daniel Ardolino]

Hi again! I've been out for a couple of hours...
> 
> So then why are you considering Cocoon?
Well, because may be a crosspoint between my standalone application/s
and some others web applications I have to do.  And of course I do 
not want to make the transformations programming java classes 
(using parsers like Xerces and Xalan) by myself, if there's 
something done in this way.

I haven't seen the links of your posts yet.  May be the answer is there.

Also I want to use some XSP logic.

I'm starting and I want to know if all the transformation classes used
by cocoon can be used by programs in the same way as cocoon does.
I mean: pipelines.

For example:

A gui program must create a screen dinamically with certain attributes
of some entity.  So by a socket it communicates with a legacy program 
requesting a XML definition file (the file contents the list of the
attributes and some constraints).  After the java program  receives 
this information, it has to apply a XSL sheet with some filters
of non desired attributes.  The resulting XML file must be converted 
to a screen or may be converted to an html to show on a browser.

May be not only a filter must be applied, may be some transformation
must (e.g. i18n).

What do you think?  Must I try to use cocoon for this?

Thanks.

Mauro

Cocoon has actions, aggregations, pseudo-protocols and other declarative goodies.

Ok, in my case, where I already have my data(&sources) bundled under 
Cocoon, I just wouldn't want to duplicate them or the presentation logic.
I'd go for a fat client (the desktop app per the original poster) making 
requests to Cocoon.

If he doesn't have a remote fat client in mind but instead want to have 
local files, you are absolutely right. I guess it all comes down to an 
accurate use case.

Thanks for the reply,

Okay, so the apparent obvious answer to my question is only obvious to me.
Look at Mauro's requirements:  standalone program, gui or batch processs,
XLS and XPath.  Yes Cocoon does utilize XPath and XSL but these are easily
utilized without Cocoon.  Given all of this, WHY would you want to go
through
the non-trivial task (if you think otherwise I suggest you go back and read
the
various installation problem posts) of setting up a servlet container with
Cocoon?

Cocoon is superfluous to Mauro's needs and can only get in the way.  Thus my
somewhat rhetorical question--rhetorical because I thought the answer to be
quite obvious.

Re: Cocoon, sockets and not a web browser.

[Dario Liberman]

Hola Mauro,
I am trying the same path for similar reasons.

I send attached a message interchange with Marcus (the Soap guru of Cocoon).

Sounds like it has to be with extending some part of the 'action' part
See http://localhost:8080/cocoon/documents/developing/extending.html

Best Regards,
Dario.

PD: Lets join efforts in this try Mauro, we can then make public some
examples of how to accomplish this.

PD2: To all the others, please let us know if you have gone with a similar
approach of having cocoon be an internal module for xml transformations
pipeline, so that one may have the input source and the output target be
both of them memory objects.

PD3: What I am looking for is to be able to do something like this: (is it
your need too?)

/* Pseudocode here inside my servlet or whatever: */
While ( manager.keepOnWorking()==true) {
/* in this example I get an XML from a soap request
but it may be any other source, Like a database XML. */
SoapObj.SyncWaitMessage();
myInputXmlDomRef = SoapObj.GetXMLRequest();

cocoonref = Cocoons.getCocoonInstance();

/* Here I add objects to a hash table So That an Xsp (or whatever) Can
Call Me for logic questions, DB interaction, etc  */
cocoonref.PutObject("mylogicClass", this);


/* Here I call cocoon with the xml input (it may be even empty), and ask
it to process the transformation pipeline (using cocoons cache and all its
cool stuff). The entry 6 in the map in this case produces an XML, so I
transform the Sax into Dom and put it in myOuputXML object. */
cocoonref.ApplyPipeline("MapEntry6",myInputXmlDomRef, myOutputXML);
/* Cocoon may call me back many times during the transformation process
through "mylogicClass" entry or EJB lookup, etc */

Try {
/* I am done! thank you cocoon! Lets send the reply:  */
SoapObj.PutResponse(myOutputXML);
SoapObj.SendXMLResponse();
} catch(error e) {
cocoonref.PutObject("error", e);
cocoonref.ApplyPipeline("MapEntry99_errorlogguer",myOutputXML,
myLogOutputStream);
/* The output may also be a stream of bytes in case of an image,
etc. For example here it is a simple text log file */
}

cocoonref.free();
}


I hope this is not too crazy an example, and that I managed to explain the
idea.
Thanks to everyone having got to here in the message, stay in contact.
Bye.

Ok, I've got come comments in your message below.

Ok. I haven't looked at jwsdp, perhaps its worth examining. The
SOAP support in Cocoon is based on Apache AXIS (not Apache SOAP
which is an older project), which has just been released as final 1.0.

Axis has passed all of the acceptance tests from Sun, so I presume
all of what is in jwsdp is in Axis somewhere.

First thing, get Cocoon 2.1 from CVS. T

maybe it's better to simply use the TRAX API and do your own SAX 
pipelines, or have a look at 
http://www.apache.org/~andyc/neko/doc/style/index.html...?
