如何使用不发送证书的Java连接到SSL服务器?

我遇到以下情况，其中Open SSL服务器在没有证书的情况下运行: openssl s_server -accept 4443 -nocert

I have a situation where an Open SSL server is running without a certificate as follows : openssl s_server -accept 4443 -nocert

如何使用Java连接到该服务器?另外，如何使用Java启动服务器以不接受证书?

How do I connect to this server using Java? Also, how do I start my server in Java to accept no certificate?

我已经附加了我一直在使用的Client.java和Server.java的代码.

I have attached the code for Client.java and Server.java that I have been using.

在客户端运行附加代码时出错:

Error while running the attached code on the client side:

Server.java

Server.java

public class Server {

    try {
        SSLServerSocketFactory sslServersocketFactory =

        if (sslSocket.isConnected())

                if (command.toLowerCase().compareTo("hello")==0)
                    response = "Bingo !! You got it write!\n";
                else
                    response = "Type Hello to see a response\n";


                OutputStream outputStream = sslSocket.getOutputStream();
                OutputStreamWriter outputStreamWriter = new OutputStreamWriter(outputStream,"UTF-8");
                outputStreamWriter.write(response, 0, response.length());
                outputStreamWriter.flush();
        }
    } catch (Exception exception) {
        exception.printStackTrace();
    }
}

}

我认为我需要使用匿名DH密码，但仍然无法正常工作.可能是我做错了.该代码也已被编辑.

I think I need to use the anonymous DH Cipher but it's still not working. May be I am doing it wrong. The code has been edited too.
