Instead of cocoon.getComponent() you have to use manager.lookup(). Look
at ServiceManager [1] for the details. It's available in your JavaScript
as you can see in ScriptAction's code.

Thanks for the information,
I took a look at ScriptAction's source code.
I have a better understanding of how it works but it seems I need to import
in my scriptAction other components and functions (DOMParser,
session.setAttribute...).
Actually I'm trying to adapt my flowscript code to a scriptAction as I need
to stay in the same sitemap after the execution of the javascript.
Here's the flowscript I'm trying to adapt.
// loadDocument() reads in an XML file and returns a DOM Document.
function loadDocument(uri) {
var parser = null;
var source = null;
var resolver = null;
try {
parser =
cocoon.getComponent(Packages.org.apache.excalibur.xml.dom.DOMParser.ROLE);
resolver =
cocoon.getComponent(Packages.org.apache.cocoon.environment.SourceResolver.ROLE);
source = resolver.resolveURI(uri);
var is = new Packages.org.xml.sax.InputSource(source.getInputStream());
is.setSystemId(source.getURI());
return parser.parseDocument(is);
} finally {
if (source != null) resolver.release(source);
if (parser != null) cocoon.releaseComponent(parser);
if (resolver != null) cocoon.releaseComponent(resolver);
}
}
// ------------------------- getStreamToSession
-------------------------------------------
// retrieve the XML
var stream = loadDocument("cocoon:/stream");
// save stream in session
var session = cocoon.session;
session.setAttribute("stream", stream);
//
---------------------------------------------------------------------------------------------
Of course, getComponent to load java components is undefined as I don't have
access to the class, the same with the parser.
I noticed that getComponent is part of org.apache.components.flow and
therefore not accessible from scriptAction.
I should be able to import java comonents with BSF.
Do you have any idea how to do it?
Thanks,
Josh

The ScriptAction works more like a usual Cocoon Java component than like
flowscript. Therefore you have the ObjectModel available which is
actually only a Map. To access the stuff you need you use the
ObjectModelHelper and call the corresponding static methods like
getRequest() or getSession() [1]. If you have a look into ScriptAction's
source code (which is simple) you will see the other objects it
registers for usage in the JavaScript:
mgr.registerBean("resolver", resolver);
mgr.registerBean("objectModel", objectModel);
mgr.registerBean("parameters", par);
// ScriptAction housekeeping
mgr.registerBean("actionMap", actionMap);
// helpers
mgr.registerBean("logger", getLogger());
mgr.registerBean("request", ObjectModelHelper.getRequest(objectModel) );
mgr.registerBean("scriptaction", this );
mgr.registerBean("manager", this.manager );
It seems the only way to access cocoon object is to create a flowscript.
Is there another solution as I don't want to redirect to another pipeline
after the script is performed unlike flowscript does?
The cocoon object is only a simplified version to access all the stuff
in the ObjectModel. It's indeed only available in flow script.
