Drugia problem e che triabva da napravia niakolko promeni po .java faila a ot java pochti nisto ne razbiram. Stava duma za edin socket server - CommServer. Promianata, koiato iskam e samo edna - da se prasta IP-to na clienta, kogato se connectne client, kogato se disconnectne client i kogato clienta prasta saobstenie. Prosto predi promenlivata "message" da ima edno "<IP>%20"+client.getIP()+"</IP>". Poluchava se nesto takova: client.send("<IP>%20"+client.getIP()+"</IP>"+message); Eto tova e sorsa:

A tova e faila: [линк]

Ste se radvam na pomost!

Po-dobre izteglete CommServer ot tuk :[линк]

Blagodaria vi predvaritelno!

tova ne6to be6e ot nqkakwa kniga....

eto k'vo moje da se naprawi:

waw faila CommServer.java

1.predi:
/**
* Broadcasts a message too all connected clients. Messages are terminated

dobawq6 :
public void broadcastMessage(String clientIp, String message) {
broadcastMessage("<IP>%20"+clientIP+"</IP>" + message );
}

2.sled:
client.start();
// --- broadcast the new number of clients

dobawq6:
broadcastMessage("<IP>%20"+client.getIP()+"</IP>" + "connected" );

3.sled:
clients.removeElement(client);

// --- broadcast the new number of clients

dobawq6:
broadcastMessage("<IP>%20"+client.getIP()+"</IP>" + "disconnected" );



i waw faila CSClient.java zamestwa6:

server.broadcastMessage(stringBuffer.toString());

sas:

server.broadcastMessage(getIP(), stringBuffer.toString());



tova e
Uspeh...

10x chovek! Problem obache mi e kompilaciata. Nesto mi dava mnogo greshki. Problem li ste ti e ako go kompilirash? 10x predvaritelno!

OS?
ili
kakwa operacionna sistema izpolzwa6?

Izviniavai, nadiavam se da ne sum mnogo nahalen, no toku sto se setih oste nesto. Kogato clienta se disconectne servera triabva da izprasta do vsichki

1-vo IP-to
2-ro vmesto "message" da ima vtori tag primerno <status>quit</status>

Ne e zaduljitelno da e tochno tova. Prosto da ima niakakva inicializacia. Tova e s cel kogato klienta se izkluchi drugite da priemat tova i ot tam natatuk az poemam nestata.

Ako mojesh pls da go kompilirash ste e mnogo dobre. Znam che stavam malko dosaden, no ot java pochti nisto ne razbiram, a mi triabvaha dva dena za da kompiliram nesto sto gode sviastno i to pak s poveche ot 20 greshki.

Blagodaria predvaritelno!

Az sum na XP. No ste raboti na drug server. Ima li niakakvo znachenie, nali e class file?

1.unzipwa6 wsi4ko v c:\comsrv
ot dos command prompta
2.cd c:\comsrv
3.del *.class
slagash si javata v tekushtia path (pri men e c:\j2sdk1.4.1)
4.set PATH=%PATH%;c:\j2sdk1.4.1\bin
5.set JAVA_HOME=c:\j2sdk1.4.1
6.javac *.class

Niamam J2SDK. Rabotia s JBuilder. S nego stava li?

path = %path%;c:\jbuilderX\jdk1.3\bin
java_home=c:\jbuilderX\jdk1.3\

Ne stava chovek! Parvo mi pravi access dained kato napisha "del *.class"!!! Sled tva ne znam kvo narichash tekust path. Kakvo iskash da kajesh s tova? Znam che vaprosa sigurno e adski tup, no se zanimavam s JAVA ot dva dena!!!

Tva za set-a go priema no "javac" komandata ne ja razpoznava.

Mnogo 10x za pomosta! Zadaljen sum ti!

1. проблема е че в тоя ZIP дето си дал линк към него всичко е с атрибути read-only, махни ги от Properties на файловете и ще можеш да ги променяш и да компилираш. Ако дава някякви други грешки пастни целия output на компилатора.
2. в момента парсването на таговете става изцяло във flash клиента. Java server-а само препраща към другите клиенти същия стринг който е получил. Ако искаш допълнителни тагове трябва да промениш и flash source-а.

Zdr, chovek! Najasno sum kak deistva chata. Mnogo dobre znam Flash-a kakvo pravi i server-a kakvo pravi. No kogato niakoi izleze ot chat clienta ili mu prekusne vrazkata na men mi triabva tova da se razbere ot drugite uchastnici v chata. Problema e che klienta ne moje kato prekasne vrazkata da izprati saobstenie nali? :) Zatova triabva server-a da go napravi. Zabeliazah che server-a taka i taka si pishe IP-to na seki koito se connectne i diskonectne, taka che reshih da vmakna edin dopalnitelen tag sadarjast IP-to kam vsiako saobstenie prastano ot srver-a. Obrabotkata v clienta si e moia rabota. Ot Flash razbiram, ama ot Java - ne!!!

10x hora za pomosta! Naistina mi pomognahte. Uspiah da kompiliram CLASS file i to po-elementarno otkolkoto predpolagah!!!

sus zdrave
