WildFly replacement for Valve in jboss-web.xml

[mylos78]

Dear all,

I'd need to upgrade a Web application deployed on JBoss AS 7 which uses some Valve attributes in jboss-web.xml for example to dump the request information. Is there an equivalent in WildFly new Web server (Undertow) ?

Thanks

I don't fully remember, but I think there was some effort to help migrate the AS7 valves to Undertow.

The equivalent concept is an HttpHandler.  You then need to create a ServletExtension that adds your custom handler to the handler chain.  You then need to create a WEB-INF/classes/META-INF/services/io.undertow.servlet.ServletExtension file to your war so that WildFly/Undertow can load your custom extension during deployment.  There's a detailed example of this here:

http://undertow.io/documentation/servlet/using-non-blocking-handlers-with-servlet.html

or by adding

WEB-INF/undertow-handlers.conf / META-INF/undertow-handlers.conf

where you just list your handlers to be executed as part of request lifecycle

How can i get the Session information in the handleRequest method ? I am trying the below code

SessionConfig sc = exchange.getAttachment(SessionConfig.ATTACHMENT_KEY);

        SessionManager sm = exchange.getAttachment(SessionManager.ATTACHMENT_KEY);

        if (sc != null && sm != null) {

        Session session = sm.getSession(exchange, sc);

            if (session != null) {

            //My action

            }

        }

But the SessionConfig and manager is always coming as null.
