Java socket client not connected to server

I get this error from my server when I call the the search animal's method. The
client connects to the server but as soon as I have clicked on the search method I get the following ERROR:
CONNECTED. getConnection
ServerConnect, searchAnimal: java.net.SocketException: Socket is not
connected
CONNECTED. getConnection
getConnection is the method to connect to database and sockets. I don't know how to fix it. Help please!
These are my declarations. I put the GUI and Server into one page of code:

The problem is here. You are creating an unconnected socket, which is pointless, and then never connecting it.

Chat server client sometimes cannot see message from other clients on the same server

I am making 2 classes for Chat server client for a project I am working on. The problem is server can see the message that sent to it(from client) and it can send those messages out to every clients BUT each client has to type in some input first if he wants to see the message from other users. I have no clue what I did wrong. Please help me out. Thanks in advance :)

You need a separate thread in the client for reading from the server without blocking on System.in;
Thread t = new Thread(() -> {
try {

System.out.println("Other user: " + in.readLine());
}

why do network socket connect and send/recieve data takes long in wireless?

I made an app client in android device (with ethernet and wireless port) and server application in windows.
Data transfers via Socket programming between devices and when i test it in emulator in PC or run in Ethernet via cable it works correctly, but when i connect server and client with wireless connectivity (via an access point) data sent or received with a delay . this delay may be take over 60 seconds !
i don't know why this problem happend !
This is my sending routin in android :
Server_Port = mDbHelper.GetPortNumber();
//mDbHelper.close();

rtsp client code not working

I am facing problem in Java socket communication, I am running Live555 Media Server and one small app (some what similar to proxy server code, referred one online code snippet) in one machine, and also created one client code and running in my laptop. All machines are in same network. When I send RTSP Command from client to proxy, It is receiving properly and it is redirecting that received command to Live555 server and its getting back proper response but the response is not receiving in client. Help me to fix this problem and also suggest me some doc link to understand the problem.
here is my proxy code,
public class TestProxyServer {

How to redirect to locally stored index.html file when localhost:<port> is called from a browser

I am creating a socket server in android. I have a directory in my local storage in which there is index.html and all other resources needed. I want that when i start the socket server and then call localhost: from my mobile's browser then it redirects to the index.html.
My socket is running. the logs are printing. the issue is i don't know how to redirect to index.html.
Thanks in advance.
