Hi, Betul,

Have you read the HttpClient SSL Guide?
http://jakarta.apache.org/commons/httpclient/sslguide.html

You should try to avoid EasySSLProtocolSocketFactory.  It makes the
security of "https" useless.  Using EasySSLProtocolSocketFactory is
like clicking on all of the following browser popups:

"The certificate for the https site is expired.  Do you still want to
continue?"

"The certificate for the https site is not signed by a trusted
authority.  Do you still want to continue?"

"The hostname specified does not match the hostname in the certificate.
Do you still want to continue?"


If you have any control or influence over the server's certificate you
should try to get a new certificate.

If not, this is probably the least insecure workaround, since the only
"warning popup" it is "clicking" is the expired certificate warning,
as opposed to all three!  (Nonetheless, this is still NOT RECOMMENDED.
 Buying a new certificate is the best way to go.)

#1.  Download not-yet-commons-ssl.jar from here:
http://juliusdavies.ca/commons-ssl/download.html

#2.  Code your use of HttpClient like so:

======================================
import org.apache.commons.ssl.HttpSecureProtocol;

HttpSecureProtocol f = new HttpSecureProtocol();
// We're okay with expired certificates.
f.setCheckExpiry( false );

// To avoid deprecation warnings:
ProtocolSocketFactory psf = f;
Protocol trustHttps = new Protocol("https-expired", psf, 443);
Protocol.registerProtocol("https-expired", trustHttps);

HttpClient client = new HttpClient();
GetMethod httpget = new GetMethod("https-expired://mydomain.com/");
client.executeMethod(httpget);
String s = httpget.getStatusLine().toString();
System.out.println( "HTTPClient: " + s );
======================================
Notice that only URL's of the form "https-expired://" will allow
expired certificates after this code has executed.  Regular "https://"
URL's still get full security.

Another option is to use Sun Java 1.3 with the JSSE extension.  That
combination doesn't bother checking certificate expiry!


yours,

Julius

The solution suggested was changing the EasySSLProtocolSocketFactory in the following way:
