Please check this function I included into XSPSessionHelper.java in
src/java/org/apache/cocoon/components/language/markup/xsp:
/** GetXML Fragment from the given session context and path
*
*
* @param session The Session object
* @param context The Session context tha define where to search
* @param path The parameter path
* @param defaultValue Value to substitute in absence of the required
Fragment
**/
public static DocumentFragment getXML(ComponentManager cm, String
context, String path) throws ProcessingException {
DocumentFragment df = null;
SessionManager sm = null;
try {
// Start looking up the manager
sm = (SessionManager)cm.lookup(SessionManager.ROLE);
// Make our work
df = sm.getContextFragment(context, path);
if (sm != null) {
cm.release(sm);
}
} catch (ComponentException ce) {
throw new ProcessingException("Error during lookup of
SessionManager component.", ce);
}
// End releasing the sessionmanager
return df;
}
Soon I will publish here too the changes in the xsp-session.xsl
I takes me 3 days!
