weblogic.net.http.SOAPHttpsURLConnection cannot be cast to javax.net.ssl.HttpsURLConnection

Question

I am getting "java.lang.ClassCastException" while trying to connect to a url using javax.net.ssl.HttpsURLConnection .

I am using 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();
}
}



}

The exception which i am getting is :

**java.lang.ClassCastException: weblogic.net.http.SOAPHttpsURLConnection cannot be cast to javax.net.ssl.HttpsURLConnection

Any possible reason of getting this error ?

Answer 1

I got the solution finally. If we are using Weblogic server, we must define:

set JAVA_OPTIONS=%JAVA_OPTIONS% -DUseSunHttpHandler=true

...in the class path inside the Server Domain.

This will tell the weblogic server to use the Sun Http Handlers and not install its own.

Answer 2

You also may explicitly define protocol handler. Just create URL using another constructor.

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

or

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

And it will make the code independent from -DUseSunHttpHandler option.

Answer 3

More detail on @KmrGtm solution:

Only thing to do is updating WebLogic domain settings in the setDomainEnv script file.

The relevant settings are in the setDomainEnv script file (setDomainEnv.cmd for Windows and setDomainEnv.sh for Linux).

The file is located in the bin subdirectory of the domain directory (/user_projects/domains//bin/) where:

• is the directory where you installed WebLogic.
• is the name of the domain where you are installing Studio.

In the file add the JAVA_OPTIONS argument close to the top of the file:

• For setDomainEnv.cmd (Windows):

set JAVA_OPTIONS=%JAVA_OPTIONS% -DUseSunHttpHandler=true

• For setDomainEnv.sh (Linux):

JAVA_OPTIONS="%JAVA_OPTIONS% -DUseSunHttpHandler=true"

export JAVA_OPTIONS

Answer 4

Begin from 12.2.1.3.0 you can to enable the new compatible HTTPS connection implementation class by using a new Java system property -DUseJSSECompatibleHttpsHandler=true to get a HttpsURLConnection instance extending javax.net.ssl.HttpsURLConnection.

weblogic.net.http.CompatibleSOAPHttpsURLConnection (extending 
javax.net.ssl.HttpsURLConnection) is returned instead of 
weblogic.net.http.SOAPHttpsURLConnection (not extending 
javax.net.ssl.HttpsURLConnection) that can avoid the ClassCastException 

Please note that when both -DUseSunHttpHandler=true and -DUseJSSECompatibleHttpsHandler=true are specified, -DUseSunHttpHandler will take precedence over -DUseJSSECompatibleHttpsHandler.
