Updated Code:- Using SSL, still am getting the same error..

I am trying to open this uri

https://some-host/a/getmeta?id=10  (this url is passed to proxi.jsp page)

And this is my proxi.jsp page, And I am getting this error HTTP/1.1 401 Authorization Required and when I am passing my credentials too. Why is it happening so.. And that site use siteminder.

Solution 1:[1]

You are accessing a secure site but I don't see any SSL handling in your HttpClient code. Can you have a look at this page and try out in a standalone client after filling in the appropriate gaps?

Solution 2:[2]

First of all from the code you posted it does not seem that you are configuring http client to use HTTPS.
You are missing code like the following (at least for org.apache.http.client.HttpClient): 

SSLSocketFactory sf = new SSLSocketFactory(sslcontext); 
Scheme https = new Scheme("https", sf, 443);
httpclient.getConnectionManager().getSchemeRegistry().register(https);

You have to check out a tutorial for DefaultHttpClient
In any case to see what's going on, you can use a sniffing tool like wireshark.
The SSL handshake is viewable and you will be able to see the connection failure and understand why.

Solution 3:[3]

Unless you know for sure that "realm" is the proper value in that AuthScope constructor, I'd recommend removing it or determine what the actual value should be.

Solution 4:[4]

change the following line: new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT, "realm")

to the following line:

new AuthScope(AuthScope.ANY_HOST, AuthScope.ANY_PORT, AuthScope.ANY_REALM)
