Different "java.io.IOException: HTTPS hostname wrong: should be ..." error

Hi
     I am experiencing some problems using SSL with Java 1.4.2_12 which appear to be subtly different to the ones posted earlier in this forum.
     ProcessA is trying to establish an HTTPS connection with an Apache server but gets the following error whilst trying to open the stream:
     java.io.IOException: HTTPS hostname wrong: should be <nnn.nnn.nnn.n>
     ProcessA obtains the IP to connect to from local config and this exactly matches the IP the IOEXception says it should be! Consequently I am confused as to why JSSE complains.
     I checked the certificates in the local keystore and the CN is also identical to the supplied IP
     I do not have the authority to tinker with the Apache configuration so I can't try anything else out. I must have missed a step somewhere but I am at a loss as to what. If anyone can shed some light on what may be happening here, I'd be obliged.
     thanks

Ejp: please accept my apologies for the hugely late response to this.
The problem was indeed at the server end. I had already employed the HostnameVerifier but after some badgering of the server admin the problem was nailed as exactyly what you said.
Thanks (and apologies) again.

Java.io.IOException: HTTPS hostname wrong: should be localhost

I'm having problems verifying an SSL client using Tomcat v5.x. I create a key in a particular keystore, let's call it C:\tomcat. I start tomcat specifying this file as the keystore to use. I then connect to the server on port 8443 with Internet Explorer and save the certificate returned from the server in a file. I then import the certificate into a keystore, let's say C:\tomcat_client. In my SSL client code I am specifiying the keystore to use with a System.setProperty("javax.net.ssl.trustStore", "C://tomcat_client"); However when I try to retrieve an output stream from a HttpURLConnection I receive the above exception. Any ideas what is happening ?
Exception : java.io.IOException: HTTPS hostname wrong: should be <localhost>
I have tried a variety of other options including importing the certificate into jssecacerts in the lib/security directory of the jre I am using to execute the SSL client, using the same keystore file for tomcat and the SSL client, etc.

Java.io.IOException: HTTPS hostname wrong

Hello
I was trying to open a connection to secure URL and post content to it.
I got the following exception:
java.io.IOException: HTTPS hostname wrong: should be <165.112.121.195>
at sun.net.www.protocol.https.HttpsClient.b(DashoA12275)
Its apparantly because the connection is
com.sun.net.ssl.internal.www.protocol.https.DelegateHttpsURLConnection
not
sun.net.ssl.www.protocol.DelegateHttpsURLConnection
I tried setting the system property
System.setProperty("java.protocol.handler.pkgs","sun.net.www.protocol");
to force JVM to use the newer Delegate.
Its still doent work. I use JDK 1.4.2_05. I deploy my application in OC4J 9.0.4
Interesting thing is, I use this code in two different applications, it works in
one and doen't work in one. Both containers use same JDK. Both are OC4J
containers.
Any thoughts? I would appreciate.
thanks
Raghavan

Do you mean?
System.setProperty("java.protocol.handler.pkgs","sun.net.ssl.www.protocol");

HTTPS hostname wrong: should be myhost

Hello everybody:
I developed some servlets using jre 1.5 and Tomcat 5.0. Now, I have to deploy them in Oracle IAS 10g 1.3.
Everything is okay, except https connection, and I don't know what to do: It works fine in Tomcat 5.0 and OC4J (oc4j_extended_101300) but not in IAS 1.3.
This is my code:
// protocol handler uses this security provider
Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
com.sun.net.ssl.HostnameVerifier hv=new com.sun.net.ssl.HostnameVerifier() {
public boolean verify(String urlHostname, String certHostname) {
System.out.println("WARNING: Hostname is not matched for cert.");//<-This is never shown
return true;
com.sun.net.ssl.HttpsURLConnection.setDefaultHostnameVerifier(hv);
And this is the server response:

Thanks in advance

you write your own little hostname verifier class (it is easy) and set it as the default. If you really dont care what the name of the servers URL is, then do this:
HttpsURLConnection.setDefaultHostnameVerifier(new YourHostnameVerifier());
YourHostNameVerifier simple has to implement HostnameVerifier interface, which is one method call. You can simply return true if you dont want it to check it (if the certificate is trusted enough, and URL does not matter).

HTTPS hostname wrong: should be myhostname

WHen I connect from my SOAP client to a SOAP server via HTTP, everything works fine. But when I connect via HTTPS, I get an exception
"HTTPS hostname wrong: should be <myhostname>"
I browsed the forums for this and got the workaround
        HostnameVerifier hv = new HostnameVerifier() {
            public boolean verify(String urlHostName, SSLSession session) {
                return true;
            public boolean verify(String urlHostName, String certHostname) {
                return true;
        HttpsURLConnection.setDefaultHostnameVerifier(hv);
        SOAPConnectionFactory scf = SOAPConnectionFactory.newInstance();
        connection = scf.createConnection(); //point-to-point connectionbut that doesn't work. Perhaps this workaround only works for url/socket connections and not for SOAP connections. Or is there a similar workaround for SOAP connections?

Well, a
Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());in addition helped. But I wonder how this host name check is done. I added a System.out with the values of urlHostName and session.getPeerHost() and after I changed my domain name to the IP address this error still occured without this workaround. So even though the urlHostName equals exactly the session.getPeerHost() string, the exception is still thrown.

"HTTPS hostname wrong" for a hostname starts with a number

Does anyone know about why HttpsClient throws the error for a hostname starts with a number. I have no problem with other hostname but only for the hostname starts with a number. The certificate works fine with Browser. I am sure the hostname in the certificate and in the request are exactly the same.
I know how to skip the hostname verification, but I don't want to do that for security concern.
Can sun develpoer shed some light how to verify the hostname in HttpsClient?

I looked at the RFCs you mention, and they do seem to indicate that host/domain names cannot start with digits...however if you look at RFC 1123 closely it says:
RFC1123 APPLICATIONS LAYER -- GENERAL October 1989
2. GENERAL ISSUES
This section contains general requirements that may be applicable to
all application-layer protocols.
2.1 Host Names and Numbers
The syntax of a legal Internet host name was specified in RFC-952
[DNS:4]. One aspect of host name syntax is hereby changed: the
restriction on the first character is relaxed to allow either a
letter or a digit. Host software MUST support this more liberal
syntax.
Host software MUST handle host names of up to 63 characters and
SHOULD handle host names of up to 255 characters.

HTTPS hostname wrong

Hi everybody,
I?m developing a client webservice throught https and I can`t connect to it, the exception thrown is:
java.rmi.RemoteException: HTTP transport error: java.io.IOException:
HTTPS hostname wrong: should be <wservices.fundacioncan.com>; nested exception is:
HTTP transport error: java.io.IOException: HTTPS hostname wrong:
should be <wservices.fundacioncan.com>This service use a basic authentication using user and password, I used the following code to set it:
System.setProperty("javax.net.ssl.trustStore","c:\\client.keystore");
System.setProperty("javax.net.ssl.trustStorePassword", "changeit");
System.setProperty("javax.protocol.handler.pkgs",
"com.sun.net.ssl.internal.www.protocol.https");
java.security.Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
         // Get our port interface
       stub._setProperty(javax.xml.rpc.Stub.USERNAME_PROPERTY, username);
        stub._setProperty(javax.xml.rpc.Stub.PASSWORD_PROPERTY, password);For calling this service I`m using a java class without a Tomcat server, and also, I have not
implemented the web service. I only know that it is hosted at
the next URL
https://wservices.fundacioncan.com:9443 and the server certificate
that i can get from the browser shows that the Subject is www.fundacioncan.com
Can anybody tell me what I?m doing wrong? I have read old topics about the same but nothing works.
Thanks in advance

You can get problems connecting over HTTPS in IE if the name on the certificate does not match the name of the site. For example if a certificate for java.sun.com had the name www.sun.com you'd get a dialog popping up saying that the name of the certificate did not match the name of the site, but that otherwise it was ok. This seems to be the error you're getting here, but you don't get the option to proceed...
I don't know whether there is a workaround for this, I only know from my experience developing my own web service that I had to ensure the server name matched the name on the certificate. It doesn't look like you have this luxury, so I'd suggest contacting the web service provider for more info, unless someone else has a workaround.

Please help - HTTPS hostname wrong.

Sorry for posting this message again. It may just be a quick help from any of you.
I have a simple https client that produced the following error message -
" java.io.IOException: HTTPS hostname wrong: should be <test.cat.com>, but cert says <*.cat.com> "
I thought that the * is the wild card,thus test.cat.com should be accepted. Any ideas?
Thanks, Jack

I am not sure exactly what to do. Anyway the code is simple. It basically first connects to a site for logon and obtain certificate (?). And then try to connect to another site.
Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
System.getProperties().put("java.protocol.handler.pkgs", "com.sun.net.ssl.internal.www.protocol");
URL url = new URL("https://login.cat.com/cgi-bin/setcookie?username=liuj&password=test"); URLConnection connection = url.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(connection.getInputStream()));
String inputLine;
while ((inputLine = in.readLine()) != null)
System.out.println(inputLine);
in.close();
url = new URL("https://eddweb.cat.com/");
connection = url.openConnection();
The exception happens at the above line -
java.io.IOException: HTTPS hostname wrong: should be <eddweb.cat.com>, but cert says <*.cat.com>
I know I have other issues need to work out later on. Right now I need to first resolve this problem. Thank you. Jack

HTTPS hostname wrong - wild card?

Thanks, Jack

ok I did exactly that and it's good. However I suggest that you don't return true automatically since it bypass completely the protection. You can easily implement the check for the domain name (which is the current implementation in jsse) and then add the wildcard special cases.
Have fun

Web service calling in HTTPS, certificate, hostname wrong

Hi
Im triying to call a web service running in WSO2 Carbon and I cant do it because I was geting a exception asking for a certificate.I had success importing a valid certificate, but now I get the following exception
HTTPS hostname wrong: should be <10.36.15.100>
this ip is the one where the WSO2 Carbon is running with the web service Im calling.
When I consume services running in other places I gat no problem and I can consume the service running in the WsO2 with the SOAP UI, so I dont Know what happend?
Thanks
Ray

Glad to help.
I actually had a similar problem a few weeks ago. I created a remote enabled FM in our R/3 system that was called by a program in our SRM system. When I ran the FM in R/3 it worked, but from SRM, no joy.
Eventually, I found that I had mispelled a parameter in the calling program. Since, the FM didn't exist in SRM, the calling program couldn't report any syntax error or give a dump. I corrected the spelling and it finally worked.

Using the DSCC to create a new proxy server instance, the proxy server can't be accessed. These messages are the result of clicking on the "Enable Access" button after proxy server creation to try and gain ldap access to the server.

Hi,
does this show for any project you try to run, or just for a specific? If it does, does the same issue show after a fresh install of JDeveloper (you don't need to delete the existing instance for this) ?

==================================
The applet is in the same directory as the ASP. It is a NT 4 (SP6) server. The applets loaded and ran fine with jdk1.3. Do I need to do something different in my ASP, or IIS setup to allow java applet HTTP connection in JDK1.4?
Thanks!

I have the exact same problem but have yet to find a solution.
It works fine in 1.3 but fails occasionally in 1.4. If I refresh the browser several times it eventually
loads.
