Why Am I Getting 'java.net.SocketException: Connection reset' Errors in My Java Network Applications?

Java Networking: Troubleshooting Connection Resets (java.net.SocketException)

When encountering "java.net.SocketException: Connection reset" errors, it's essential to consider the following causes:

1. Intentional Client Reset
The client may have deliberately closed the connection using improper means. While uncommon, this can be observed in commercial software.

2. Protocol Error
Attempts to write on a connection that has been closed by the client can result in this error.

3. Buffer Management
Closing a socket with unread data in the receive buffer can trigger the error.

4. Network Issues
In Windows, network problems during data transmission can lead to "software caused connection abort." Consult Microsoft's knowledge base for further details.

5. Process Handling
Windows resets connections if a process closes without properly shutting down the socket. However, other operating systems, such as Unix and Linux, close connections cleanly.
