javax.net.ssl.HttpsURLConnectionを使用してURLに接続しようとしているときに "java.lang.ClassCastException"が表示されています。weblogic.net.http.SOAPHttpsURLConnectionをjavax.net.ssl.HttpsURLConnectionにキャストできません
私はWeblogic Server 10.3.4を使用しています。

SSLContext sc = SSLContext.getInstance("SSL");
sc.init(null, trustAllCerts, new java.security.SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());

HostnameVerifier allHostsValid = new HostnameVerifier() {

// Install the all-trusting host verifier
HttpsURLConnection.setDefaultHostnameVerifier(allHostsValid);
String urlstr="https://www.google.co.in";
URL url = new URL(urlstr);
HttpsURLConnection conn = (HttpsURLConnection)url.openConnection();
conn = (HttpsURLConnection)url.openConnection();
if (conn instanceof javax.net.ssl.HttpsURLConnection) {
System.out.println("*** openConnection returns an instanceof javax.net.ssl.HttpsURLConnection");
}
if (conn instanceof HttpURLConnection) {
System.out.println("*** openConnection returns an instnace of HttpURLConnection");
}
conn.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
BufferedReader reader = null;
reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
for (String line; (line = reader.readLine()) != null;) {
System.out.println("##### line iz :::"+line);
}
}
catch(Exception e)
{
e.printStackTrace();
}
}
}
私は取得しています例外は次のとおりです。
**java.lang.ClassCastException: weblogic.net.http.SOAPHttpsURLConnection cannot be cast to javax.net.ssl.HttpsURLConnection

このエラーを取得してのいずれかの可能性のある理由は？
あなたの 'instanceof'テスト*をキャストの後に置くことにはあまり意味がありません。あなたが使っていないクラスにキャストする際には何のポイントもありません。 URLConnectionとして使用するだけです。 – EJP
'instanceof'はテスト目的でのみ使用されました。キャストエラーがこの行に表示されています:: HttpsURLConnection conn =（HttpsURLConnection）url.openConnection（）; – KmrGtm
