Hmpf, I don't get it to work. Btw, I get the context from the
SessionManager, but you made me curious about the session-context input
module (mainly because the XPath). Here's my method (I have the manager
object as an instance variable and only use the session-context, so it
slightly differs from the method proposed by John):
private String getInputModuleAttribute(String path) {
ServiceSelector selector = (ServiceSelector)
manager.lookup(InputModule.ROLE + "Selector");
InputModule inputModule = (InputModule)
selector.select("session-context");
return (String) inputModule.getAttribute(path, null, null);
}
Of course I handle the exceptions (and none is thrown btw), but I left that
out for readability purposes.
So I tried many ways to get just one parameter:
getInputModuleAttribute("//id"));
getInputModuleAttribute("/authentication/ID"));
getInputModuleAttribute("//ID"));
getInputModuleAttribute("session-context:authentication/ID"));
getInputModuleAttribute("session-context:authentication//ID"));
getInputModuleAttribute("session-context:authentication/authentication/ID"))
;
but all I get in return is null.
http://cocoon.apache.org/2.1/apidocs/org/apache/cocoon/webapps/session/compo
nents/ContextInputModule.html#getAttribute(java.lang.String,%20org.apache.av
alon.framework.configuration.Configuration,%20java.util.Map) says, that null
is returned if the value doesn't exist. Huh?
The value is there - I can get it by calling
sessionManager.getContextFragment("authentication", "/authentication/ID")).
Where's my daily mistake this time? :)
Cheers,
Stefan

| Yes, quite: getInputModuleAttribute(manager,"session-

|
| You can use an XPath expression like:
|
| getInputModuleAttribute(manager,"session-context","//id")
