Hi,
I am new to HttpClient and applying version 3.x for my application. All I
know about my application which I am writing is that I have to invoke a URL
something like this http://xyz.com:8303/cics/bcwa/AG80R and I have to send
user ID and password to connect to that url which gives me back xml String.
Now when I try to write the client code to call that URL above,
HttpClient client = new HttpClient();
client.getParams().setParameter("http.useragent", "Test
Client");
// pass our credentials to HttpClient, they will only be used
for
// authenticating to servers with realm "realm" on the host
// "www.verisign.com", to authenticate against
// an arbitrary realm or host change the appropriate argument to
null.
client.getState().setCredentials(
new AuthScope("http://xyz.com";, 8303),
new UsernamePasswordCredentials("opensesame", "opensesame")
);
// create a GET method that reads a file over HTTPS, we're
assuming
// that this file requires basic authentication using the realm
above.
PostMethod get = new
PostMethod("http://xyz.com:8303/cics/bcwa/AG80R ");
get.setRequestEntity(new StringRequestEntity(data.toString(), null, null));
get.setDoAuthentication( true );
try {
// execute the GET
int status = client.executeMethod( get );
// print the status and response
System.out.println(status + "\n" +
get.getResponseBodyAsString());
} finally {
// release any connection resources used by the method
get.releaseConnection();
}
I get errors as below
