Urgent: Requirement - Ability to extract o/p from resources - SunShine developers - please peruse this and provide comments

[Chitharanjan Das <cd...@accordiasys.com>]

Hello All,


I have the following requirement ....................

I have created a set of pipelines (resources) that execute a set of
logic and spit out XMLs (results)

Now What I want is that somehow get hold of that XML as  a String and do
further manipulations like sending the result to another pipeline for
instance.


To be more illustrative:

The resources are
	1. Validate Item
		<map:match pattern = "validateItem >
			.....
		</map>
	2. Is present in Inventory
		<map:match pattern = "InventoryCheck" >
			....
		</map>
	3. GetPrice
		<map:match pattern = "priceValidate" >
			....
		</map>


In a XSP or an action , I would like to do the following
	Parameters.setParameter("itemId",itemId);
	DocumentFragment item =
resource.getXMLData("validateItem",parameters);
	String itemXML = getXMLStringFromDocumentFragment(item);

	If(validate(itemXML) {
		DocumentFragment inventoryItem =
resource.getXMLData("InventoryCheck ",parameters);
	}
	else 
		reportItemInvalid(
	and so on ...........


Also I could use the above resources in pipelines using map:call to
generate html o/p



I am not talking in the blind here,
	The sunshine developers use this mechanism in authenticating a
user, creating a new user and so on..
  But their code is centric on using sunshine Component.

I was wondering, is there a standard way of doing this and is it
documented some place.

Thanks in advance,
Chiths

The following XSP code snippet, does the required ..
However, this is an implementation of the sunrise component.
Which does not implement cocoon:/ (cocoon Relative URI)

<xsp:logic>
		ResourceConnector resourceConnectorComponent = null;
		 try {
		      resourceConnectorComponent =
(ResourceConnector)
	
this.manager.lookup(ResourceConnector.ROLE);
		     } catch (ComponentException ce) {
		       throw new ProcessingException("Error during
lookup of 					sunShine resource
connector.", ce);
            }
	    	String uri = "cocoon://prd/xsp/test/links";
    		Resource resource = new Resource(resolver, uri);
	    	String data = null;
    		System.out.println("resource is "+resource);
	    	if(resource != null) {
    			data =
resourceConnectorComponent.getContent(
				resource.getResourceType(),
parameters,resource.getResourceIdentifier(),
				parameters);
	//
    		System.out.println("Data is :"+data); 
    	}
</xsp:logic>

Is there any provision in the Basic Cocoon package to do this
functionality ....

Regds,
Chiths
