java.net.SocketException: Software caused connection abort: recv failed
Hi!
�
I use HttpClient to connect to different websites which are all under the same domain. After having connected to a site and brought its html-code to my java-program, I wait 5 seconds until I connect to the next site (using Thread.sleep).
�
I start by making one HttpHost and defining a HttpEntity and HttpRespons
�
final HttpHost target = new HttpHost("www.xxxxxxx.se", 80, "http");
HttpEntity entity = null;
HttpResponse rsp = null;
�
After that I use a loop to connect to each subsite, having the adresses urlEnding. I write the following in the loop:
�
HttpRequest req = createRequest(urlEnding);
rsp = client.execute(target, req);
String[] line = EntityUtils.toString(rsp.getEntity()).split("\n");� //this info is used by program
if (entity != null){
� entity.consumeContent();
}
�
And now to my problem:
�
After having connected to a number of websites (the number varies) I often get a java.net.SocketException. Please see the attached bmp-file for the whole stack. In the case of the attached file, I manage to connect to 243 websites before the exception is thrown.
�
Interestingly, the java-function that should send me an e-mail after the HttpClient is finished with its work then also throws an exception (IpClientException). I suppose these problems are connected in some way.
�
Best regards,
Sul Adna

Thanks for the reply Oleg. Is it possible to tell HttpClient to try to reconnect a certain number of times (e.g. every 5:th second during 1 minute) before the exception is thrown? I guess the thing that interrupts it is something temporary.

Sul Adna,
HTTP connections somethings get terminated abnormally for various
reasons, for instance, due to a firewall dropping the connection or the
target server being under heavy load.
A well behaved HTTP agent ought to be prepared to deal with I/O
exceptions of that kind.
Hope this helps
