ClassCastException in HttpsURLConnection

I try to connect to https://verisign.com using HttpsURLConnection..and i get :
Exception in thread "main" java.lang.ClassCastException: com.sun.net.ssl.internal.www.protocol.https.HttpsURLConnectionOldImpl
     at URLReader.main(URLReader.java:22)
code:
     java.security.Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
     System.setProperty("java.protocol.handler.pkgs","com.sun.net.ssl.internal.www.protocol");
     System.setProperty("javax.net.ssl.trustStore","/home/httpd/servlets/cacerts");
URL verisign = new URL("https://www.verisign.com/");
HttpsURLConnection cx =(HttpsURLConnection)verisign.openConnection();
     BufferedReader in = new BufferedReader(
     new InputStreamReader(verisign.openStream()));
     String inputLine;
     while ((inputLine = in.readLine()) != null)
     System.out.println(inputLine);
     in.close();
Is this problem connected with wrong certificate?
But why is it a CastException?
Please help thanks.

Had this one.
You probably use the new class:
javax.net.ssl.HttpsURLConnection and verisign uses
older com.sun.net.ssl.HttpsURLConnection.

ClassCastException using HttpsURLConnection with Tomcat 4.1.27

Hi,
I try to open an SSL connection using HttpsURLConnection that works fine with a standalone application (see code fragment):
import javax.net.ssl.HttpsURLConnection;
import java.net.*;
import java.io.*;
URL website = new URL( "https://aSampleSSLSite" );
HttpsURLConnection connection = ( HttpsURLConnection ) website.openConnection();
Using the same code in Tomcat 4.1.27 and Struts 1.1 throws a java.lang.ClassCastException while trying to use website.openConnection().
What is the difference?

Hi,
I'm using JDK 1.4.2 and haven't installed JSSE separately at all. Actually I really use javax.net.ssl.HttpsURLConnection. However, I tried com.sun.net.ssl.HttpsURLConnection as well and got a 'java.net.SocketException: Default SSL context init failed' instead of.
Oddly enough the code works fine in a standalone application.

HttpsURLConnection gives ClassCastException in Weblogic 5.1

am getting an error when i run my application in weblogic 5.1 as
java.lang.ClassCastException: weblogic.net.http.HttpsURLConnection.
I know the reason after creating URLConneciton the object i am getting
is "weblogic.net.http.HttpsURLConnection" instead of com.sun.net.ssl.HttpsURLConnection
But if I run this application outside weblogic environment my application is running fine.
How do I make the weblogic server to pick com.sun.net.ssl.HttpsURLConnection instead of weblogic.net.http.HttpsURLConnection.
Thanks in advance
Arshad

Are you casting the object to com.sun.net.ssl.HttpsURLConnection?
Why not just use javax.net.HttpsURLConnection? I have never worked with
WebLogic before, but I'm sure it will extend that class.

ClassCastException - HttpsURLConnection

I am getting the following error:
java.lang.ClassCastException: com.ibm.net.ssl.internal.www.protocol.https.HttpsURLConnection
Does anybody have a solution to this? I am developing in WSAD 5.
if (protocol.equalsIgnoreCase("https"))
//use Sun's JSSE to deal with SSL
//java.security.Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
System.out.println("1");
System.setProperty( "java.protocol.handler.pkgs","com.ibm.net.ssl.internal.www.protocol");
System.out.println("2");
java.security.Security.addProvider(new com.ibm.jsse.IBMJSSEProvider());
//System.getProperties().put("java.protocol.handler.pkgs", "com.sun.net.ssl.internal.www.protocol");
//System.getProperties().put("java.protocol.handler.pkgs", "com.ibm.net.ssl.internal.www.protocol");
System.out.println("3");
url = new URL(protocol + "://" + hostname + "/" + prefix + "/" + service);
System.out.println("4");
connection = (HttpsURLConnection) url.openConnection(); //this is where the error is occuring
System.out.println("5");
else
url = new URL(protocol + "://" + hostname + "/" + prefix + "/" + service);
connection = (HttpURLConnection) url.openConnection();
}

Okay, maybe I have t reversed :P There are two HttpsURLConnections, one in javax.net the other one you are using. If you have imported one or both, you will have to qualify which you mean:
connection = (com.ibm.net.ssl.internal.www.protocol.https.HttpsURLConnection) url.openConnection();And make sure connection is instantiated as:
com.ibm.net.ssl.internal.www.protocol.https.HttpsURLConnection as well.

HTTPS ClassCastException for SOAPHttpsURLConnection to HttpsURLConnection

JDEV 11gR1PS1
Hi all,
I'm writing a Java class that posts via HTTPS. I'm getting the the following error when executing the class:
java.lang.ClassCastException: weblogic.net.http.SOAPHttpsURLConnection cannot be cast to javax.net.ssl.HttpsURLConnection
using the following code (just a snip of what's relevant:
            url = new URL(nurl);
            connection = (HttpsURLConnection)url.openConnection();
            responseCode = connection.getResponseCode();I've also tried based on some research on the web
            url = new URL(null, nurl, new com.sun.net.ssl.internal.www.protocol.https.Handler());
            connection = (HttpsURLConnection)url.openConnection();
            responseCode = connection.getResponseCode();and instead I this error
java.lang.ClassCastException: com.sun.net.ssl.internal.www.protocol.https.HttpsURLConnectionOldImpl cannot be cast to javax.net.ssl.HttpsURLConnection
Ideas?

Import this instead
import weblogic.net.http.SOAPHttpsURLConnection;
and then when attempting the connection try using the SOAPHttpsURLConnection object

ClassCastException while instantiate HttpsURLConnection

When I try to instantiate an HttpsURLConnection from an URL instance called "Server,"
HttpsURLConnection conn =(HttpsURLConnection) server.openConnection();I got the following exception:
java.lang.ClassCastException: sun.net.www.protocol.http.HttpURLConnection incompatible with javax.net.ssl.HttpsURLConnection
May I know if there is anyway to solve it? I have to use HttpsURLConnection.
Thank you!

Hi,
you did not provide your import statements contained in the class. Please check which class named HttpsURLConnection you are trying to import.
Maybe your import refers to sun.net.www.protocol.http..., which is imcompatible with the one in javax.net.ssl....
Bye.

ClassCastException in Tomcat 4.1. Pointing to old HttpsURLConnection

Hi There
My servlet casts ClassCastException when I try to craete HttpsURLConnection instance from URL.openConnection(). Here are the facts.
OS = Linux RH 8.0
JDK Version = 1.4.2
Tomcat Version = 4.1
$JAVA_HOME is set to the JDK 1.4.2
Here's the code:
URL u = new URL("https://url/to/the/site");
javax.net.ssl.HttpsURLConnection connection = (javax.net.ssl.HttpsURLConnection)u.openConnection();
This causes ClassCastException.
Then I found out that the URL.openConnection() is acutually returning an instance of com.sun.net.ssl.HttpsURLConnection. And this is what is causing this problem.
So my qustion is how I can point Tomcat to use javax.net.ssl.HttpsURLConnection instead of old com.sun.net.ssl.HttpsURLConnection.
JAVA_HOME is set to the newest version of JDK (1.4.2) and I don't know whereelse Tomcat looks for files... Do I have to change the conf files?
I would greatly appreciate your help.
Michi

hello Michi,
I am assuming that you are using the TOMCAT that comes with Java Web Services Developer's pack from java.sun.com. First DownLoad and install the JDK in question (the one that you want catalina to use). Then set the value of JAVA_HOME in the catalina.sh file in the <CATALINA_HOME>/bin folder. Just tinker with it for sometime, trying to set the JAVA_HOME variable. This should be enough to change your java.home to the new JDK.
IF that does not work, then you may have to change the system 'path' variable as well. That should do it.
First try out the first one. Try the second one only if the first one does not work.
all the best,
Pawan

Why didn't you call ResultSet.getDouble(columnIndex) or Resultset.getFloat(columnIndex) in the first place, rather than whatever you did? Then the database driver would have handled the data translation for you instead of making you do all that nasty casting.

for URL'S Starting with HTTPS only.....Sometimes it works and sometimes it gives me the classcast exception
As soon as I bounces my Apache application server...then it starts working...I dont know why its happening like that..
Is there any issue with the Ports I am trying to connect or some Apache configuration files settings are getting changed ?

How to use JSSE HttpsURLConnection in WL 5.1

you should use specifal constructor .. for url..
some thing like..
URL( "https","www.verisign.com","443","",new
com.sun.net.ssl.internal.www.protocol.https.Handler());

Thanks again! I get "This is incorrect" when applying your test, which I expected, because I tried to cast using that full path (javax.net.ssl.HttpsURLConnection) and it failed.
There was a runtime version of java on my computer before I installed the J2SE.... it is in a directory called j2re1.4.1_02. I just left it there when I installed j2sdk1.4.2 in a different directory. Do you think this could cause my problem? I'll can try uninstalling the older runtime version.
Also, the only thing in my CLASSPATH is a period followed by a semicolon. Is that correct or should I point to a classes directory in j2sdk1.4.2? And, I have nothing in my PATH regarding java.... is that a problem?

Servlet/Tomcat using HTTPsUrlConnection error

Hello all,
I am fairly new to java/tomcat and am attempting to develop an SSO connection. When I get to the following line of code in my servlet
HttpsURLConnection httpConn = (HttpsURLConnection)sso.openConnection();
I receive the following error:
SingleSignOn threw exception
java.lang.ClassCastException: sun.net.www.protocol.http.HttpURLConnection cannot be cast to javax.net.ssl.HttpsURLConnection
Any help is much appreciated.
Regards,

Yes that is one of the issues I have. Thanks for the assistance.

ClassCastException: HttpsURLConnectionOldImpl

I am working with jdk 1.4.0 and the incorporated JSSE and I am using Tomcat 4.0.3 with SSL. I am attempting a secure connection to a url, using https. When I try to cast my URLConnection object to a javax.net.ssl.HttpsURLConnection I receive the exception below in Tomcat. Note, I have successfully communicated between client/server over secure sockets, (reading/writing from the designated port's stream) but my goal is to use the HttpsURLConnection class. Thanks in advance for your assistance.

I've got the same problem with Tomcat 4.1.18 through 24 under JDK 1.4.1_02. I've tried every logical setting for the handler.protocol, including javax.net.ssl.internal.www.protocol, javax.net.ssl, and many others as well as sun.net.www.protocol from looking at the structure of the jsse.jar in JDK 1.4. But the (apparent) Tomcat continues to (apparnetly) ignore my setting.
Have you learned anything specific here? Do you have any other suggestions? ... I'm fresh out of ideas!
