java - Is it a good practice to override implementation of ServletContextListener? -
i have developed web service using jax-ws , in web.xml had servlet context listener registered.
<listener> <listener-class>com.sun.xml.ws.transport.http.servlet.wsservletcontextlistener</listener-class> </listener>
but, have specific function done when web service , when web service down. way think of, create servletcontextlistener
, and add in web.xml
.
but override 1 specified (as shown above <listener>
tag).
my worry in case wsservletcontextlistener
might implementing servletcontextlistener
methods , must doing specific work in it.
i tried extend wsservletcontextlistener
class final cannot. way can take wsservletcontextlistener
instance member listener class , wrap methods provided it. practice?
make own listener , declare in new <listener>..</listener>
tag. 2 listeners should invoked in order specified in web.xml.
