Hi Udit,
I believe the problem is that technically the subdomain
("donotdelete_httpclient", in your case) can't have underscores.
So the URI class will return null for the hostname.
The same thing would happen if you had a subdomain that started with a
"-", for example "-angelcries.blogspot.com"
In HttpClient 3.x, there was a custom URI class that was more lenient,
but in 4.x the standard Java URI class is used.
Even though these are technically invalid hostnames, most (all?) DNS
servers will resolve them properly, which is why the URL works in a
browser, but fails with HttpClient 4.
I believe Oleg's standard response is that you should use HttpCore
directly if you need to work with non-standard hostnames.

Hi,
I am using httpclient4.0.1.jar for get request in my code.earlier i
was
using commons-httpclient-3.1.jar for the same.
For httpclient4.0.1.jar
====================================================
My code block is as follows :
conn = new DefaultHttpClient();
HttpHost host = new HttpHost("s3.amazonaws.com",80);
HttpGet request = new HttpGet();
request.setURI(new
java.net.URI("https://donotdelete_httpclient.s3.amazonaws.com/4F265439.jpg?AWSAccessKeyId=AKIAINHDRCMKC5GUSNFA&Expires=1276089613&Signature=Xxm%2FmOttPqs0F0jvx%2Fv%2FTQCJPsg%3D
"));
request.setParams(params);
HttpResponse response = conn.execute(request);
response.setParams(params);
While Executing this request (red marked line)I am getting an
exception as
"Host name may not be null"(illegal argument exception) and If i run
this
URI on browser then it is running fine.
=====================================================
For commons-httpclient-3.1.jar
My code block for same URI is as follows :
HttpClient httpClient = new HttpClient();
HostConfiguration secureHostConfig = new HostConfiguration();
GetMethod method = null;
method = new
GetMethod(https://donotdelete_httpclient.s3.amazonaws.com/4F265439.jpg?AWSAccessKeyId=AKIAINHDRCMKC5GUSNFA&Expires=1276089613&Signature=Xxm%2FmOttPqs0F0jvx%2Fv%2FTQCJPsg%3D
);
statusCode = httpClient.executeMethod(secureHostConfig, method);
For this code block it is running fine.
=======================================================
Can any one help me what I am missing out as I want to upgrade
commons-httpclient-3.1 to httpclient4.0.1.
Thanks and regards to your responses.
Regards-
Udit
