weblogic.net.http.SOAPHttpsURLConnection non può essere trasmesso a javax.net.ssl.HttpsURLConnection

Question

Ricevo "java.lang.ClassCastException" durante il tentativo di connettersi a un URL utilizzando javax.net.ssl.HttpsURLConnection.

Sto utilizzando Weblogic Server 10.3.4.

import javax.net.ssl.HostnameVerifier; 
import javax.net.ssl.HttpsURLConnection; 
import javax.net.ssl.SSLContext; 
import javax.net.ssl.SSLSession; 
import javax.net.ssl.TrustManager; 
import javax.net.ssl.X509TrustManager; 



import java.security.cert.X509Certificate; 


import java.io.BufferedReader; 
import java.io.InputStreamReader; 

import java.net.HttpURLConnection; 
import java.net.URL; 

/**

public class GatewayConnect { 


public void ConnectURL() 
{ 
    try 
    { 

     System.out.println("***** Inside Class File *****"); 
    // Create a trust manager that does not validate certificate chains 
    TrustManager[] trustAllCerts = new TrustManager[] {new X509TrustManager() { 
      public java.security.cert.X509Certificate[] getAcceptedIssuers() { 
       return null; 
      } 
      public void checkClientTrusted(X509Certificate[] certs, String authType) { 
      } 
      public void checkServerTrusted(X509Certificate[] certs, String authType) { 
      } 
     } 
    }; 

    // Install the all-trusting trust manager 
    SSLContext sc = SSLContext.getInstance("SSL"); 
    sc.init(null, trustAllCerts, new java.security.SecureRandom()); 
    HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory()); 

    // Create all-trusting host name verifier 
    HostnameVerifier allHostsValid = new HostnameVerifier() { 
     public boolean verify(String hostname, SSLSession session) { 
      return true; 
     } 
    }; 

    // 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(); 
} 
} 



} 

L'eccezione che sto ottenendo è:

Qualsiasi possibile motivo di questo errore?

Answer 1

Ho finalmente trovato la soluzione. Se stiamo usando WebLogic Server, dobbiamo definire:

set JAVA_OPTIONS=%JAVA_OPTIONS% -DUseSunHttpHandler=true

... nel percorso di classe all'interno del server di dominio.

Questo dirà al server weblogic di utilizzare i Sun Http Handler e di non installarne uno proprio.

Answer 2

Maggiori dettagli su soluzioni @KmrGtm:

L'unica cosa da fare è aggiornare le impostazioni del dominio WebLogic nel file di script setDomainEnv.

Le impostazioni pertinenti si trovano nel file di script setDomainEnv (setDomainEnv.cmd per Windows e setDomainEnv.sh per Linux).

Il file si trova nella sottodirectory bin della directory di dominio (/ user_projects/domini // bin /) dove:

• è la directory in cui è stato installato WebLogic.
• è il nome del dominio in cui si sta installando Studio.

Nel file aggiungere l'argomento JAVA_OPTIONS vicino alla parte superiore del file:

• Per setDomainEnv.cmd (Windows):

set JAVA_OPTIONS =% JAVA_OPTIONS% -DUseSunHttpHandler = true

• Per setDomainEnv.sh (Linux):

JAVA_OPTIONS = "% JAVA_OPTIONS% -DUseSunHttpHandler = true"

JAVA_OPTIONS esportazione

Answer 3

Si può anche definire in modo esplicito gestore di protocollo. Basta creare URL usando un altro costruttore.

URL url = new URL(null, urlstr, new sun.net.www.protocol.http.Handler()); 

o

URL url = new URL(null, urlstr, new sun.net.www.protocol.https.Handler()); 

e renderà il codice indipendente dalla -DUseSunHttpHandler opzione.
