HTTPPost usage error to in execution method

Question

Hi all,

I am using the following code to make a http client ,i am facing problem in execute method ,its getting stuck there.

public static final HttpHost target = new HttpHost("test.xyz.com", 443, "https");

public static void test()
{
    HttpEntity responseEntity = null;
    DefaultHttpClient client = new DefaultHttpClient();
    HttpPost post = new HttpPost("/xyz/test");
    System.out.println("post is " +post.getRequestLine());

        UsernamePasswordCredentials credentials = new UsernamePasswordCredentials(username, password);
        AuthScope authScope = new AuthScope(target.getHostName(), target.getPort());
        System.out.println("auth scope is " +authScope);
        client.getCredentialsProvider().setCredentials(authScope, credentials);
        //i am passing a xml here
        post.setEntity(new StringEntity(xml, "UTF-8"));
        post.addHeader("Content-Type", "application/xml");
        post.addHeader("Accept", "application/xml");
        System.out.println("post " +post.getAllHeaders().length);
        HttpResponse response = client.execute(target, post); //getting stuck here no response at all
        System.out.println("response  " +response.getStatusLine());
        responseEntity = response.getEntity();
        System.out.println("response entity " +responseEntity);
        String responseXmlString = EntityUtils.toString(responseEntity);
        System.out.println("response" +responseXmlString);


}

i am facing problem here

HttpResponse response = client.execute(target, post);

what might be wrong ?

The problem is the code is getting stuck in client.execut method its not moving furthur neither i am getting any response.Do i have to set any proxy?

Answer 1

Probably your request is not really 'stuck' but just waiting on a TCP connection timeout, which bu default could be quite lonkg - like 5 minutes or so. There should be a way to set timeout to shorter value - take a look at javadoc for your http client or just try to wait longer.

Also you can take a thread dump while your program is stuck to see where the thread is blocked (see jps and jstack utilities in Sun's JDK)

Answer 2

I think you first need to eliminate the possibility of your server misbehaving. Have you tried POSTing to that URL from outside of your program. Try something like this if you are on a unix-like system or are on windows and have cygwin:

cat <yourfile.xml> | curl -X POST -H 'Content-type: text/xml' -d @- https://test.xyz.com:443/xyz/test

If the POST is successful get a thread dump of your program and post it here for us to take a look.
