How to correctly communicate between two different MVC Controllers in Java Swing? -

-

can explain me how controller can call controller method in simple still correct way?

please provide code!

background: have 2 different controllers-view-model , 2 libraries , need communicate between each other:

  1. settingswindow/settingscontroller/settingsmodel: responsible app settings. model singleton because need settings data on app;

  2. a library monitoring directory creates event every time file created in specific directory. monitored dir path defined in settingsmodel; i'm using java 7 watchservice api that;

  3. a library monitoring webserver , download new files. webserver address , save directory both defined in settingsmodel; i'm using httpsurlconnection , timer that;

  4. mainwindow/maincontroller/mainmodel: responsible main app window, has table must updated every time new file created in monitored directory, , everytime file downloaded above libraries.

so how correctly instantiate , communicate 4 different features?
how controllers commnuicate between them, since related? how should organize project in terms of mvc?

please provide basic mvc scaffold (skeleton) , show create instances, , how call each others method. i'm new java, specially swing , mvc. i've read lot, got stuck in situation.

as suggested here, patterns such model-view-controller , observer represent recurring design elements. simple outline may illustrate interaction of classes, general solution beyond scope of stackoverflow.

still, may useful @ how principles might applied. suppose following tutorial , have implemented watchservice in swingworker, shown here. now, suppose want main view, jtable, update in response arriving watchevent. arrange corresponding tablemodel register worker propertychangelistener, shown here , here. when propertychangeevent arrives, update tablemodel , fire appropriate event update jtable. known tablemodel implementations include required methods.

a similar approach used update table in response data arriving web.

for settings, consider java.util.preferences, mentioned here, or javax.jnlp.basicservice, discussed here.

i need set custom soap header attribute on jax-ws generated webservice client. case webservice calls must go through proxy server requiring specific token (recieved web request header) present in soap request header. e.g.: 1 carserviceservice service = null; 2 service = new carserviceservice(new url(url), new qname(qname); 3 carserviceendpoint port = service.getcarserviceport(); it seems in line 3 wsdl retrieved , call fails due missing security token. 1 point direction on how done? a detailed example has been mentioned here: creating , deploying jax-ws web service on tomcat 6 this article shows how create , use security token .
