Hi,
You can get your context-related sessions through the ContextManager: http://cocoon.apache.org/2.1/apidocs/org/apache/cocoon/webapps/session/ContextManager.html
Here you can manage all your session context stuff through the SessionContext object:
http://cocoon.apache.org/2.1/apidocs/org/apache/cocoon/webapps/session/context/SessionContext.html
eg:
[1] In my flow I use the following to get information from the authentication session (or another context related session):
var contextMan = null;
try{
contextMan =cocoon.getComponent(Packages.org.apache.cocoon.webapps.session.ContextManager.ROLE);
var sessionContext = contextMan.getContext("authentication");
var id = sessionContext.getValueOfNode("/authentication/ID");
var myData = sessionContext.getXML("/authentication/data/myData");
}
finally{
cocoon.releaseComponent(contextMan);
}
[2] In my custom generator I can do the same by extending from a ServiceableGenerator (has a manager to lookup stuff like in the flow sample)
and basically do the same as the previous code:
public class myGenerator extends ServiceableGenerator{
ContextManager contextManager = (ContextManager) this.manager.lookup(ContextManager.ROLE);
SessionContext sessionContext = contextManager.getContext("authentication");
String role = sessionContext.getValueOfNode("/authentication/role");
DocumentFragment documentFragment = sessionContext.getXML("/authentication/data/mydata");
}
The same way you can create/manage your own context related sessions.
Kind regards, Jan

Hi; i'll try to be as clear as possible because i have seen that before i have not been too clear :-) I use the authenthication framework for log user; for this reason the framework creates the authentication session context; in this context there is an xml token so made:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<authentication xmlns:sql="http://apache.org/cocoon/SQL/2.0";> <ID>carmelo</ID>
<role>static value undefined</role> <data> <token> <permesso id="PM-GR-1" /> <permesso id="PM-GR-2" /> <permesso id="PM-GR-3" /> <permesso id="PM-GR-4" /> <permesso id="PM-GU-1" /> </token> <idutente>1</idutente> <username>carmelo</username> <password>carmelo</password> <nome>yyyy</nome> <cognome>yyyy</cognome> <email>[EMAIL PROTECTED]</email> <stato>ON</stato> </data> </authentication>
Now i'ld like to read this xml from a Java class..... how can i do?
I have written this code:
import org.apache.cocoon.webapps.authentication.context.AuthenticationContextProvider; import org.apache.cocoon.webapps.session.context.SessionContext; import org.apache.cocoon.ProcessingException;
import org.apache.log4j.Logger;

public class CocoonSesionTest {
private static Logger log = Logger.getLogger( CocoonSesionTest.class.getName() );
public CocoonSesionTest() {
}
public String getDocFrag(){
AuthenticationContextProvider au = new AuthenticationContextProvider();
log.info( "$$$$$$$$$$$$$ au è: "+ au );
try {
log.info( "Calling: au.getSessionContext(authentication).getXML(authentication).getNodeName()" );
if( au == null ){
return "Addirittura au era null";
}
SessionContext sc = au.getSessionContext("authentication");
if( sc == null ){
return "Il session Context era null";
}
return "Il valore di ID è: "+sc.getValueOfNode( "ID" );
}
catch (ProcessingException ex) {
log.error( ex );
ex.printStackTrace();
return null;
}
}
public String toString(){
return "Sono il tuo CocoonSesionTest";
}
}
I have tried to use it in a flowscript:
function buildUserHomePage() {
log.info("--buildUserHomePage-- send loggedHome.jx");
log.info( "########## Calling test ###################" );
var test = new CocoonSesionTest();
if( test == null ){
log.info( "Era nullo" );
}else{
log.info( "Non era nullo e ho avuto: "+ test.toString()+" Ora vediamo il metodo" );
log.info( test.getDocFrag() );
}
log.info( "########## Test Called ###################" );
cocoon.sendPage( "loggedHome.pjx" );
}
This function is called when the user i logged successfully; but i have this exception:
11:23:06,467 INFO [Admin module] ########## Calling test ###################
11:23:06,828 INFO [Admin module] Non era nullo e ho avuto: Sono il tuo CocoonSesionTest Ora vediamo il metodo
