java - Xmpp Vs Websocket -

i'm develop website has near real time chat. know can implemented using xmpp or websocket protocols. know xmpp protocol has been developed in 1999 , , guess should mature nowadays .on other hand , websocket protocol has been developed in 2011.

what need websocket if xmpp in handling real time conversations? what major differences between 2 protocols? and when should take 1 of them on other?

the short reply 'both'.

xmpp set of application protocol doing real-time chat (and many other things, matter) - has transported across network somehow, need transport binding. there 3 main transport bindings xmpp -

tcp/ip, 1 uses on net native clients on devices http (called bosh), 1 has traditionally used when using xmpp in browser (as tcp-ip isn't available javascript apps in browser) websockets, 1 1 uses when doing xmpp in modern browser.

so if you're developing chat application in browser, you'd take xmpp application protocol , you'd utilize websockets (in modern browser) or bosh (in older browser) network transport. if utilize xmpp library javascript stanza.io (https://github.com/otalk/stanza.io), it'll back upwards both , you'll thinking 'xmpp' rather transport layer, other @ setup when have tell endpoint connect to.

(you can't utilize 'just websockets' chat - can utilize websockets without xmpp, means you're inventing own application-layer protocol chat, , odds you're going save lot of time , headaches taking advantage of work that's gone writing 1 useful properties (security, identity, extensibility etc.) , there existing libraries , servers going xmpp instead.)

java - Bypassing "final local variable defined in an enclosing type" - i'm writing programme , i'm getting "the final local variable asd cannot assigned, since it's defined in enclosing type". i provide illustration not code produces error aswell. have arraylist utilize later (if define within button can't utilize later on), outside of button, pressing button should give values arraylist. in illustration "create new arraylist" cause same problem. button btn = new button("asd"); final arraylist asd = new arraylist(); btn.setonaction(new eventhandler<actionevent>() { public void handle(final actionevent event) { asd = new arraylist(); //here's error.. } }); clear arraylist , add together values. java javafx
