SocketException inside IOException

Question

I'm getting java.net.SocketException in the portion of code with try-catch IOException with no output of errors. SocketException is a successor of IOException so why?

try {
        Socket net = new Socket(TARGET, PORT);
        sendRawLine("GET / HTTP/1.1", net);
        sendRawLine("request", net);
        net.close();
    } catch (IOException e) {
        // System.out.println(e);
    }

Very simple. For why you need to read a liner here docs.oracle.com/javase/7/docs/api/java/net/SocketException.html if you need further help paste your code and tell us what you did and what are you expecting? — SMA

@chiastic-security line 15 is just exucutes a method with this code — andy007

at com.Joorvish.sendRawLine(Joorvish.java:125) at com.Joorvish.createSockets(Joorvish.java:99) This makes me suspect that sendRawLine is somehow used wrongly. Do you have some Docu about that method? — Fildor

You need to post the whole of the method that this code appears in, along with its signature, and also line 15 that invokes it. — chiastic-security

@Andy So you need to post the code of sendRawLine() for evaluation. Surely this is obvious? and the request for the code? and the stack trace? How exactly do you expect people to help you here? Magic? — user207421

java.net.SocketException: Broken pipe

This means you've written to a connection that has already been closed by the peer. The reason for that is almost certainly the invalid HTML that you appear to be writing.
