I'm trying to do an API using SSL. When I perform the call, I get the following error:
org.springframework.web.client.ResourceAccessException: I/O error on GET request for "https://yyyyy.zzz/123":sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target; nested exception is javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
I know there are many questions in StackOverflow regarding this issue, but the ones I saw was because certificate was self-signed. In this case certificate is valid and browser recognize it without problems as a valid one.
So my question is, why does it fail when calling from Java and it does work well when using the browser?
I had same issue. The browser recognized the certificate (and certificate path), but Java Virtual Machine did not. The error text was the same.
In my case the trust root was in Browser keystore, and in Java trust keystore. So everyone could check thrust path. But if your server returns not the whole certificate path, but only server one, it is harder. In this case, the certificate path could be validated only if validator has the INTERMEDIATE certificate in its thrust-store.
Because the java keystore is not updated as regularly as these in browsers, you could have the intermediate certificate in browser, but not in JVM.
Possible solutions in this case:
server to return the whole certificate chain
the intermediate certificate to be added in java trust store

After applying the latest Windows Updates I'm getting an:
Error 500--Internal Server Error
trying to access my URL using HTTP (not HTTPS!) protocol.
Looking in Weblogic logs, I found this error:
ServletContext#199346236[app:analytics module:analytics path:/analytics spec-version:2.5 version:11.1.1]] Root cause of ServletException.
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: timestamp check failed
How can I solve this issue?
I don't know where I can find this expired certificate and if this is the real problem because I'm not using an HTTPS protocol trying to access my site.
You will have to find the location of your certificates first or your certificates are located in your keystore. If so, you can display content of your keystore and check which certificates you have.
Do you use Weblogic in combination with OSB? If yes, then the keystore is propably configured in your Enterprise Manager. If not, then your keystore is configured on Weblogic level which can be found at servers -> keystores tab
I don't know if this is the solution but let's try it out.
I'm trying to find how I can allow only for specific host to be trusted in Apache HttpClient java.
I connect to the server using Apache HttpClient via https. The server has self-signed certificates, hence I keep getting the following error :
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

I know that we can skip certification verification for all hosts (we can trust all hosts and certifications), but my question is how can we disable certification or trust only for single specific host I want? I need to it all programatically.
I am accessing a web service. When I go to the web service's URL in my browser, the certificate is signed and automatically is accepted.
What I don't understand is that when I use Java to access the web service I get something along the lines of:
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
I would imagine this means that the certificate is not signed, but it is.
Doesn't com.sun.net.ssl.internal.ssl go to the certificate authority automatically and check if the certificate is signed? If not, is there something I need to set up in addition in order to do this?
There is more checking than just the signature. The certificate authority that produced the signature must be validated, among other things. Java's list of trusted certificate authorities is different than your browser's. You may need to download the CA cert with your browser and install it with Java's keytool.
It seems that the web server or the URL you are connecting to does not have a valid certificate from an authorized CA.To solve see this alternative solution.
I am trying to trouble shoot a two way SSL handshake mechanism. I get an error
Caused by: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
This indicates that one of my keystore or my truststore files does not have the appropriate entries. I know the way to trouble shoot this is to go to the server's truststore do the keytool list check the signing authorities and come to the client's key/truststore and verify this.
Can someone list these steps clearly (with the appropriate commands) please? Googling is not leading me anywhere. I just need a list of steps of "How can I confirm that Client X can talk to Server Y with two way SSL using Cert Z"?
The SunCertPathBuilderException exception is thrown whenever there the certificate validator fails to establish a chain between the certificate and a root certificate.
The easiest way to confirm that the certificate validates is to use a graphical tool like
Keyman, or
KeyTool IUI
The above tools are recommended since the exception is usually thrown in the absence of a root certificate.
If you want to examine what certificates are getting exchanged, it is better to switch on the ssl debug flag on the JVM node where the validation is failing.
Another option is to use a network traffic capture utility like Ethereal or Microsoft Netmon to obtain a dump of the traffic containing the certificate exchanges.
PS: Are you using the right keystore in the first place? I remember doing the same mistake many moons ago...
I'm trying to read from a secure (i.e. SSL) web page, in Java code.
I'm trying to use both URLConnection (java.net) and Apache's HTTPClient.

Note that I've succeeded in establishing a non-ssl connection, to a different host though.
I'm also able to view this page using the browser - the certificates are validated correctly there.
Do you I need to somehow change the order of certificates as they are retrieved from the server?
Is there some configuration I'm missing?
Thanks in advance,
Lior
I dug in further and the answer lies in the fact that I needed to import the necessary certificates into the keystore used by the JVM to authenticate SSL.
The key store is the 'cacerts' file under the jre/lib/security folder in the jre that is used to run the program.
I manually exported the site's certificates - all of them.
Then I imported it into my default keystore using the 'keytool' utility provided by Sun. Note that you have to import them in the correct order.
I then put the new keystore instead of the JRE's one - and it worked.
I guess it would've been better to import the certificates directly to the JRE's keystore, but the tool asked me for a password which i didn't know.
I believe there's also a way to program around this more easily, just haven't found it yet. I'll be happy to get some pointers (TrustManager class in JSSE?).
Finally, some credit. This post here: http://javaishdiscoveries.blogspot.com/2009/02/battle-with-cacerts-and-https.html helped to point me in the right direction.

google says it may be problem with certificate chain order, I have just found that my cert is not in order, not fixed yet, working on it. I will update this later.
old post:
Have almost the same problem.
Adding certificate manualy to keystore helps, but I'd prefer to do it more automatically, with my client.
So my solution:
I will use keystore just for this one app, and one host
1. keystore does not exist - create with some generated password
2. save password in config file
3. ask user (or dont) whether he wants to accept this certificate
4. if so - save it to keystore, and use it when needed
Is this a good solution? Any comments?
The problem was with certificate chain order.
It was: A->C->B, but should be A->B->C, once we fixed chain order the application started to work.
I havent personally fixed the certs. but this post was helpful
