Question

I have the following code:

ServerSocket ss = new ServerSocket(2351);

Socket s = ss.accept();
InputStreamReader in = new InputStreamReader(s.getInputStream());
writer = new PrintWriter(s.getOutputStream());
writer.flush();

cbuf = new char[buf_length];
in.read(cbuf);
inputLine = new String(cbuf);

I ran four consecutive sends to my server and when I debug the above code it runs correctly three times. The other time the following is my inputLine that is read from the socket:

POST /record HTTP/1.1
Content-type: application/soap+xml;charset="utf-8";action=""
Accept: application/soap+xml, multipart/related, text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
User-Agent: JAX-WS RI 2.1.5-b03-
Host: localhost:2351
Connection: keep-alive
Content-Length: 2197

And the content is just 2197 whitespaces instead of a 2197 length content. Its really weird and I am stuck. Any help is appreciated. Thanks.

I’ll try to make EJP’s answer more concrete. Instead of

n.read(cbuf);
inputLine = new String(cbuf);

You need to do something like:

StringBuilder sb = new StringBuilder();
int charsRead;
while ((charsRead = n.read(cbuf)) != -1) {
    sb.append(cbuf, 0, charsRead);
}
inputLine = sb.toString();

This may not be the answer to the question you are asking, but it is definitely a bug in the code you posted.
