Thanks for your reply Stuart,

i have the handler "HAHandler" configured as filter in the undertow subsystem of wildfly.

I also have eager filter initialization on filter enabled.And the Filter init() method is getting called while application deployment and it had set the servletContext.

<response-header name="server-header" header-name="Server" header-value="WildFly/10"/>

<response-header name="x-powered-by-header" header-name="X-Powered-By" header-value="Undertow/1"/>

<error-page name="500Handler" path="${jboss.home.dir}/welcome-content/ErrorPage.html" code="506"/>

<error-page name="404Handler" path="${jboss.home.dir}/welcome-content/ErrorPage.html" code="404"/>

</filters>

You were correct, by adding some logs, the sevletInitalHandler hadn't added the attachment when my handler was called.

any suggestions how to move my handler in the chain after a specific handler (ServletInitailHandler)?

Where is your handler running? It sounds like it is running outside
the ServletInitialHandler, which is what sets the attachment key.

If that is the case you can either move the handler to be run after
the ServletInitialHandler, or save the ServletContext somewhere
static.
