ObjectOutputStream out = new
ObjectOutputStream(mojeUrlConnection.getOutputStream());
out.writeObject(mojObiekt);

pytanie:

p.s. ponizsza skladnia nie pomaga:

ObjectInputStream dane = new ObjectInputStream(req.getInputStream());


a moze jakies inne sugestie?

No wlasnie... problem w tym ze nic...

samo req.getInputStream() ma:
org.apache.catalina.connector.CoyoteInputStream@3da850a ObjectInputStream
dane = new ObjectInputStream(req.getInputStream()); wywala to:ARNING:
Servlet.service() for servlet gameservlet threw exception

java.io.EOFException

at java.io.ObjectInputStream$PeekInputStream.readFully(Unknown Source)

at java.io.ObjectInputStream$BlockDataInputStream.readShort(Unknown Source)

at java.io.ObjectInputStream.readStreamHeader(Unknown Source)

at java.io.ObjectInputStream.<init>(Unknown Source)

itd...
