Apache HttpClient SSL javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated

Programação Java

Ola,
estou tentando acessar um url HTTPS com um certificado e recebo o erro:

javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated
       at com.sun.net.ssl.internal.ssl.SSLSessionImpl.getPeerCertificates(SSLSessionImpl.java:352)
       at org.apache.http.conn.ssl.AbstractVerifier.verify(AbstractVerifier.java:128)

       at org.apache.http.impl.client.AbstractHttpClient.execute(AbstractHttpClient.java:554)

Os passos que eu fiz foram:
1 - Instalei via assitente do windows o certificado(arquivo .pfx).
2- exportei gerando um .cer
3- importei o .cer com o comando:

keytool -importcert -file <PATH>/myFile.cer

4 - gerei o .jks com o comando:

keytool -importcert -file <PATH>/myFile.cer -keystore <PATH>/myFile.jks -storepass myStorePass

e o seguinte codigo:

        DefaultHttpClient httpclient = new DefaultHttpClient();

        KeyStore trustStore  = KeyStore.getInstance(KeyStore.getDefaultType());        
        InputStream instream = HTTPSClient.class.getResourceAsStream("/myFile.jks"); 
        try {
            trustStore.load(instream, "myStorePass".toCharArray());
        } finally {
            instream.close();
        }
        
        SSLSocketFactory socketFactory = new SSLSocketFactory(trustStore);
        Scheme sch = new Scheme("https", socketFactory, 443);
        httpclient.getConnectionManager().getSchemeRegistry().register(sch);

        HttpPost httppost = new HttpPost(url);

        System.out.println("executing request" + httppost.getRequestLine());
        
        HttpResponse response = httpclient.execute(httppost);

conforme exemplo dos docs:
http://svn.apache.org/repos/asf/httpcomponents/httpclient/branches/4.0.x/httpclient/src/examples/org/apache/http/examples/client/ClientCustomSSL.java

Alguem sabe o que pode estar acontecendo?
