Re: Java Autopostback?

I'm writing a web server in Java for html and servlets.
when the server receives a GET request, it works fine.

problem: when I use POST, the server program stops and the submit
button has to be clicked another time or the page has to be manually
refreshed (after that it works fine).
so, the program waits for the client to send a new signal/request.
The problem is caused by a in.readLine() statement:

if(method.equals("GET") && URI.contains("?"))
paraLine = URI.substring(URI.indexOf("?")+1, URI.length());
else if(method.equals("POST"))
paraLine = in.readLine(); // in the POST request, the
parameters are in the http request body

how to avoid that?

I don't think the bug is in those four lines. What you need is a good
debugger and I recommend jSwat: http://jswat.sourceforge.net/

yes, it was, and I solved the problem using read() instead of readLine() in
this way:

else if(method.equals("POST"))
{ // POST method
int ch;
int len = Integer.parseInt((String)
headers.get("Content-Length")); // POST request Content-Length header
paraLine = "";
for(int i=1; i<=len; i++)
{
ch = in.read();
paraLine += (char) ch; // in the POST request,
the parameters are in the http request body
}
}

By the way, you can also pass GET-like parameters to a POST request:
POST somefile.php?hello=world HTTP/1.1

this is fun
