java.net.UnknownHostException
Hi,
I am using HTTPConnection to get a connection to an URL. It works fine when
I give just the IP address but when I specify the full path it gives me
following exception
java.net.UnknownHostException: 201.173.335.213/xxxx/xxxxx
at java.net.InetAddress.getAllByName0(InetAddress.java:571)
at java.net.InetAddress.getAllByName0(InetAddress.java:540)
at java.net.InetAddress.getByName(InetAddress.java:472)
at java.net.Socket.<init>(Socket.java:100)
at
org.apache.commons.httpclient.protocol.DefaultProtocolSocketFactory.createSo
cket(DefaultProtocolSocketFactory.java:104)
at
org.apache.commons.httpclient.HttpConnection.open(HttpConnection.java:488)
at TrialConnectionClient.main(TrialConnectionClient.java:237).
What am I missing ? I've pasted the code
HttpConnection oHttpConnection = new
HttpConnection(strURL,440);
logMessage("Connected before"+
oHttpConnection.isOpen() );
logMessage("Connected before"+
oHttpConnection.getProxyHost());
logMessage("Connected before"+
oHttpConnection.getPort());
oHttpConnection.open();
logMessage("Connected after"+
oHttpConnection.isOpen() );
RequestOutputStream oRequestOutputStream = new
RequestOutputStream(oHttpConnection.getRequestOutputStream(),false);
logMessage("Output Stream ");
strXml = "inputXml="+sbInputXML.toString();
oRequestOutputStream.println(strXml);
//oRequestOutputStream.close();
logMessage(" Input Stream ");
BufferedReader oBufferedReader = new
BufferedReader(new
InputStreamReader(oHttpConnection.getResponseInputStream()));
logMessage("Opening the input Stream");
String line;
System.out.println(System.currentTimeMillis());
logMessage("Buffered Input starting to read");
while ((line = oBufferedReader.readLine()) != null)
{
System.out.println(line);
sbXMLText.append(line + "\n");
}

Re: java.net.UnknownHostException
Posted by Michael Becke <be...@u.washington.edu>.
Please take a look at the following URL as an example of how to use
HttpClient to read from a server:
http://cvs.apache.org/viewcvs/jakarta-commons/httpclient/src/examples/
BasicAuthenticatonExample.java?rev=1.3&content-type=text/vnd.viewcvs-
markup
It seems that the problem is that you are attempting to read directly
from an HttpConnection. Though this seems logical given how the
java.net.UrlConnection works, HttpClient handles things a little
differently. All posts, gets, etc. are done via HttpMethods like
PostMethod and GetMethod. HttpConnection is not meant to be used
directly.
