java target - Resolving javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed Error?




7 Answers

You need to add the certificate for App2 to the truststore file of the used JVM located at %JAVA_HOME%\lib\security\cacerts.

First you can check if your certificate is already in the truststore by running the following command: keytool -list -keystore "%JAVA_HOME%/jre/lib/security/cacerts" (you don't need to provide a password)

If your certificate is missing, you can get it by downloading it with your browser and add it to the truststore with the following command:

keytool -import -noprompt -trustcacerts -alias <AliasName> -file <certificate> -keystore <KeystoreFile> -storepass <Password>

Afer import you can run the first command again to check if your certificate was added.

Here is the original issue:-

I am getting this error

detailed message sun.security.validator.ValidatorException: PKIX path building failed:
sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

cause 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 am using tomcat 6 as webserver. i have two https webbapplication installed on different tomcat on differte port but on same machine. Say App1(port 8443) and App2(port 443). App1 connects to App2 .When App1 connects to App2 i get above error. I know this is very common error so came across many solutions on different forums and sites. I have below entry in server.xml of both tomcat i.e

keystoreFile="c:/.keystore" 
keystorePass="changeit"

Every site says the same reason that certificate given by app2 is not in the trusted store of app1 jvm. This seems to be true also when i tired to hit the same URL in IE browser, it works(with warming, There is a problem with this web site's security certificate. here i say continue to this website) But when same url is hit by java client(in my case). So i get the above error. So to put it in trustore i tried these tree options i.e

Option1

System.setProperty("javax.net.ssl.trustStore", "C:/.keystore");
System.setProperty("javax.net.ssl.trustStorePassword", "changeit");

Option2 Setting below in environment variable

CATALINA_OPTS -- param name
-Djavax.net.ssl.trustStore=C:\.keystore -Djavax.net.ssl.trustStorePassword=changeit ---param value

Option3 Setting below in environment variable

JAVA_OPTS -- param name
-Djavax.net.ssl.trustStore=C:\.keystore -Djavax.net.ssl.trustStorePassword=changeit ---param value

But nothing worked .

What at last worked is executing the java approach suggested in How to handle invalid SSL certificates with Apache HttpClient? by Pascal Thivent i.e executing the program InstallCert.

But this approach is fine for devbox setup but i can not use it at production environment.

I am wondering why three approaches mentioned above did not work when i have mentioned same values in server.xml of app2 server and same values in truststore by setting

System.setProperty("javax.net.ssl.trustStore", "C:/.keystore") and System.setProperty("javax.net.ssl.trustStorePassword", "changeit");

in app1 program.

For more information this is how i am making the connection

URL url = new URL(urlStr);

URLConnection conn = url.openConnection();

if (conn instanceof HttpsURLConnection) {

  HttpsURLConnection conn1 = (HttpsURLConnection) url.openConnection();

  conn1.setHostnameVerifier(new HostnameVerifier() {
    public boolean verify(String hostname, SSLSession session) {
      return true;
    }
  });

  reply.load(conn1.getInputStream());



How to work-it in Tomcat 7

I wanted to support a self signed certificate in a Tomcat App but the following snippet failed to work

import java.io.DataOutputStream;
import java.net.HttpURLConnection;
import java.net.URL;

public class HTTPSPlayground {
    public static void main(String[] args) throws Exception {

        URL url = new URL("https:// ... .com");
        HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();

        httpURLConnection.setRequestMethod("POST");
        httpURLConnection.setRequestProperty("Accept-Language", "en-US,en;q=0.5");
        httpURLConnection.setDoOutput(true);
        DataOutputStream wr = new DataOutputStream(httpURLConnection.getOutputStream());

        String serializedMessage = "{}";
        wr.writeBytes(serializedMessage);
        wr.flush();
        wr.close();

        int responseCode = httpURLConnection.getResponseCode();
        System.out.println(responseCode);
    }
}

this is what solved my issue:

1) Download the .crt file

echo -n | openssl s_client -connect <your domain>:443 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ~/<your domain>.crt
  • replace <your domain> with your domain (e.g. jossef.com)

2) Apply the .crt file in Java's cacerts certificate store

keytool -import -v -trustcacerts -alias <your domain> -file ~/<your domain>.crt -keystore <JAVA HOME>/jre/lib/security/cacerts -keypass changeit -storepass changeit
  • replace <your domain> with your domain (e.g. jossef.com)
  • replace <JAVA HOME> with your java home directory

3) Hack it

Even though iv'e installed my certificate in Java's default certificate stores, Tomcat ignores that (seems like it's not configured to use Java's default certificate stores).

To hack this, add the following somewhere in your code:

String certificatesTrustStorePath = "<JAVA HOME>/jre/lib/security/cacerts";
System.setProperty("javax.net.ssl.trustStore", certificatesTrustStorePath);

// ...



For me, this error appeared too while trying to connect to a process behind an NGINX reverse proxy which was handling the SSL.

It turned out the problem was a certificate without the entire certificate chain concatenated. When I added intermediate certs, the problem was solved.

Hope this helps.




Another reason could be an outdated version of JDK. I was using jdk version 1.8.0_60, simply updating to the latest version solved the certificate issue.




i wrote a small win32 (WinXP 32bit testet) stupid cmd (commandline) script which looks for all java versions in program files and adds a cert to them. The Password needs to be the default "changeit" or change it yourself in the script :-)

@echo off

for /F  %%d in ('dir /B %ProgramFiles%\java') do (
    %ProgramFiles%\Java\%%d\bin\keytool.exe -import -noprompt -trustcacerts -file some-exported-cert-saved-as.crt -keystore %ProgramFiles%\Java\%%d\lib\security\cacerts -storepass changeit
)

pause



I have this problem too.

I tried almost everything by adding the SSL cert to .keystore, but, it was not working with Java1_6_x. For me it helped if we start using newer version of Java, Java1_8_x as JVM.




In my case the issue was that the webserver was only sending the certificate and the intermediate CA, not the root CA. Adding this JVM option solved the problem: -Dcom.sun.security.enableAIAcaIssuers=true

Support for the caIssuers access method of the Authority Information Access extension is available. It is disabled by default for compatibility and can be enabled by setting the system property com.sun.security.enableAIAcaIssuers to the value true.

If set to true, Sun's PKIX implementation of CertPathBuilder uses the information in a certificate's AIA extension (in addition to CertStores that are specified) to find the issuing CA certificate, provided it is a URI of type ldap, http, or ftp.
