java - How to Limit ServletListener to a Single Context? -

i have jsr-356 websocket application. use listeners initialize it, don't need rely on jar scanning annotations slows down startup.

for example, use servletcontextlistener implementation register websocket's endpoint:

@override public void contextinitialized(servletcontextevent sce) {      servercontainer servercontainer = (servercontainer) sce         .getservletcontext()         .getattribute("javax.websocket.server.servercontainer");      servercontainer.addendpoint(myendpoint.class); } 

and register listener in web.xml deployment descriptor:

<listener>   <listener-class>my.servletcontextlistenerimpl</listener-class> </listener> 

the problem endpoint registered of web contexts, not want.

how can limit listener specific contexts? or set "init params" on listener via configuration can inspect in servletcontextlistener , register endpoint if matches init param?

each webapp own servletcontext, wouldn't possible have single servlet listener respond multiple webapp contexts that.

something else going on in situation.
