Hello, good morning, good afternoon or good evening, I'm having a problem, with a system I'm creating, thank you to anyone who can help. So, this system basically passes a "protocol" to the servers and it returns an object, and vice versa, however, when you end the client and reopen without doing the same with the server, a server error is caused, and when trying doing some return of an object after re-opening the client is caused an error.
Server error closing client:
java.net.SocketException: Connection reset at java.net.SocketInputStream.read(SocketInputStream.java:210) at java.net.SocketInputStream.read(SocketInputStream.java:141) at sun.nio.cs.StreamDecoder.readBytes(StreamDecoder.java:284) at sun.nio.cs.StreamDecoder.implRead(StreamDecoder.java:326) at sun.nio.cs.StreamDecoder.read(StreamDecoder.java:178) at java.io.InputStreamReader.read(InputStreamReader.java:184) at java.io.BufferedReader.fill(BufferedReader.java:161) at java.io.BufferedReader.readLine(BufferedReader.java:324) at java.io.BufferedReader.readLine(BufferedReader.java:389) at main.java.Manager.run(Manager.java:45)
Client error when reopening and trying to get object:
