SSL Error: unable to find valid certification path to requested target

Question

I am trying to connect to a url through my server that requires certificate. I have imported my Client Authentication Certificate to {JAVA_HOME}/jre/bin/security/cacerts and also i have placed it in the keystore in Jboss/bin and jboss/server/conf/ then i restarted my server and it is still giving me the folowing error.

I want to ask what can i do to fix it? Do i need to put another one of these in server.xml for this certificate:

<Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true" maxThreads="150"
   scheme="https" secure="false" strategy="ms" address="${jboss.bind.address}"
   keystoreFile="${jboss.server.home.dir}/conf/.keystore"
   keystorePass="changeit" sslProtocol="TLS"
   truststoreFile="/usr/lib/jvm/java-6-sun-1.6.0.10/jre/lib/security/cacerts"
   truststorePass="*****"
   SSLImplementation="org.jsslutils.extra.apachetomcat6.JSSLutilsImplementation"
   acceptAnyCert="true" clientAuth="want" />

or am i making anyother mistake?

Answer 1

I know you said you already imported the certificate, but take a look at these steps to see if you missed a step somewhere:

Here's an overall summary of how to import certificates to fix the following error:

Error while trying to execute request. 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

How to import certificates

1. Go to URL in your browser, click on HTTPS certificate chain (little lock symbol next to URL address) to export the certificate
   • Click "more info" > "security" > "show certificate" > "details" > "export..".
   • Save as .der
   • Repeat for any certificates you need to import
2. Locate $JAVA_HOME/jre/lib/security/cacerts

3. Import all *.der files into the cacerts file using the following:

   sudo keytool -import -alias mysitestaging -keystore $JAVA_HOME/jre/lib/security/cacerts -file staging.der
   sudo keytool -import -alias mysiteprod -keystore  $JAVA_HOME/jre/lib/security/cacerts -file prod.der
   sudo keytool -import -alias mysitedev -keystore  $JAVA_HOME/jre/lib/security/cacerts -file dev.der
   

4. The default keystore password is 'changeit'

5. You can view the change that you made with this command that shows the Certificate fingerprint.

   keytool -list -keystore $JAVA_HOME/jre/lib/security/cacerts
   

6. If this doesn't solve the problem, try adding these java options as arguments:

   -Djavax.net.ssl.trustStore="$JAVA_HOME/jre/lib/security/cacerts"
   -Djavax.net.ssl.trustStorePassword="changeit"
