[undertow-dev] Undertow servlet context

[Rohan Emmanuel]

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.


  <filters>
                    <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"/>
                    <filter name="HAHandler" module="com.haHandler"
class-name="com.HAHandler"/>
                </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)?
