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
