I am new in JAVA, Consuming web service(.wsdl) in Web Service Client project. I import the client certificate in java cacerts store in jrd. My code is as follows:
System.setProperty("javax.net.ssl.trustStore","[PATH]/cacerts.jks");
System.setProperty("javax.net.ssl.trustStorePassword","changeit");
ServicesProxy service = new ServicesProxy();
ServiceRequest request = new ServiceRequest(1498);
ServiceResponse response = service.getDetails(request);
I'm failed to handshake, I am getting the following exception:
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 have no clue why there is an exception. Any help will be appreciated.
You probably have to add the key chain in the certificate (PEM format).
CA Root -> Intermediate Cert -> Cert.
Or the certificate cannot be found in the keystore, do you use the correct alias etc.
And I do not recognize the SOAP JAX-WS implementation you use.
Not a solution to your problem, but maybe it helps to find it:
You can start your client with the VM parameter -Djavax.net.debug=all which will give you a lot of information about the SSL connection.
Check here for details about the output:
https://docs.oracle.com/javase/7/docs/technotes/guides/security/jsse/ReadDebug.html
Use -Djavax.net.ssl.trustStore property directly instead.
One more thing the server you use in that also u need to place the jks for handshake.
For example server is JBoss then bin
I guess your cacert is not correct or the path is unaccessible. I followed the instructions given here
Use SSL Poke to verify connectivity
Download SSLPoke.class
Execute the class as follows, changing the URL and port:
$JAVA_HOME/bin/java SSLPoke yoururl 443
A successful connection would look like this:
$JAVA_HOME/bin/java SSLPoke yoururl 443
Successfully connected
Try to use a different truststore to connect
$JAVA_HOME/bin/java -Djavax.net.ssl.trustStore=[PATH]/cacerts.jks SSLPoke yoururl 443
If it fails the truststore does not contain the proper certificates.
How to solve it
The solution is extracted from here
Fetch the certificate again from the server:
openssl s_client -connect yoururl:443
You need openssl. Save the output to a file called public.crt. This is how your file should look like:
-----BEGIN CERTIFICATE-----
< Bunch of lines of your certificate >
-----END CERTIFICATE-----
Import the certificate:
$JAVA_HOME/bin/keytool -import -alias -keystore $JAVA_HOME/jre/lib/security/cacerts -file public.crt
Enter the password if prompted (the default is changeit)
Recommendation
In the same post it is not recommended to use a configured trustStore different than the JVM cacert because then java could not access other root certificates.
This is a quite common error while dealing with soap services over SSL, I've had it a few times.
Your certificate may not be correctly installed in your truststore.
You can use openssl to check and install the correct certificate in the truststore, as explained here
Hi Looks like certificates are not imported correctly or path used in code not pointing to correct keystore.
I hope following steps in below article will help you.

I'm a bit lost of how I can use certificate in WidlFly 11. I re the doccumentation and found a lot of terms like JSSE, OpenSSL, Elytron, ApplicationRealm.
The problem occurs when I execute the code
final URL url = new URL("https://someUrl");
HttpsURLConnection httpURLConnection = (HttpsURLConnection)url.openConnection();
This exception is thrown sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
So, what exactly need to configure? I tried the section "Enable One-way SSL/TLS for Applications" in Elytron Doccumentation but didn't works.
ps: I'm using java 9.01
ps2: I'm using standalone-full.xml
let me know if you need more informations
This is unrelated to WildFly - you need to configure certificates trusted by java URL connections - you need to create and configure truststore:
create keystore containing certificate of server (if it is self-signed certificate), or better, certificate of its CA:
keytool -import -file myCA.cert -alias myCA -storepass mypassword -noprompt -keystore my.truststore
start using created keystore file as truststore in WildFly by setting javax.net.ssl.trustStore and javax.net.ssl.trustStorePassword system properties:
bin/jboss-cli.sh -c
/system-property=javax.net.ssl.trustStore:add(value="/path/to/my.truststore")
/system-property=javax.net.ssl.trustStorePassword:add(value="mypassword")
Elytron documentation you mention is related only to server side - but this is client side configuration, which is not currently handled by it.
The certificate is not trusted, iirc there is a self-signed certificate in WildFly 11 so yo need to trust it or install a real certificate.
Accept server's self-signed ssl certificate in Java client
We're in a scenario where a corporate proxy is decrypting all HTTPS traffic and re-signing it with a CA ROOT which Java does not trust.
We're also in a scenario where we are unable to modify the cacerts file in the Java directory.
We're getting the following issue in many Java applications:
sun.security.validator.ValidatorException: PKIX path building failed:
sun.security.provider.certpath.SunCertPathBuilderException: unable to find
valid certification path to requested target
We don't want to have to add individual certificates.
What we can do is change JVM arguments however:
-Dtrust_all_cert=true has no effect
-Dhttps.proxyHost=localhost -Dhttps.proxyPort=8888 has no effect
With step 2 we are trying to go through Fiddler as a proxy but no requests appear when we do HTTPS requests.
If we set -Dhttp.proxyHost=localhost -Dhttp.proxyPort=8888 and do HTTP requests we see the traffic in Fiddler. So...
Why doesn't trust_all_cert help here?
Why doesn't Java use the https proxy we specify?
NB: We've even tried making a java program hardwired to use localhost:8888 as a proxy. Again, works for HTTP but not HTTPS.
One way is to make a new cacerts file and use that in the JVM:
Download the CA Root certificate (e.g. root.cer)
keytool -import -noprompt -trustcacerts -alias root -file root.cer -keystore .\cacertsnew -storepass ***
java -Dhttps.proxyHost=someproxy -Dhttps.proxyPort=8080 -Djavax.net.ssl.trustStore=cacertsnew ...
Currently I try to make a play application be able to communicate SSL encrypted with the database.
I created self-signed certificate and CA for mysql. There is no problem with that normally, I can make the application communicate with the db server encrypted, when I add this CA to the JAVA_OPTS
-Djavax.net.ssl.trustStore=/app/path/conf/truststore
Everything goes well until my application not tries to communicate with other sites via SSL:
java.net.ConnectException: General SSLEngine problem to https://api.twitter.com/1/statuses/oembed.json?<meh>
[...]
Caused by: javax.net.ssl.SSLHandshakeException: General SSLEngine problem

[...]
The error is pretty obvious: twitter's ssl cert cannot be checked, because my truststore doesn't contains the CA which signed twitters certificate. IIRC I cannot add more than one "javax.net.ssl.trustStore" parameter for JVM, so I have to inject my CA's into the play framework. For luck, play framework supports ssl, and regarding the documentation I can add multiple truststores: https://www.playframework.com/documentation/2.4.x/WsSSL
I created a config file for ssl:
play.ws.ssl {
trustManager = {
stores = [
{ path: /path/to/truststore, type: "JKS", password = "<whatever is it" }
{ path: ${java.home}/lib/security/cacerts } # Default trust store
]
}
But when I start the server, I got the following error message:
Oops, cannot start the server.
java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty
And now, I am stuck. I can inject my truststore for JVM, but when I do this, the app cannot communicate with other SSL enabled hosts - there's no cert, but when I try to add my truststore for play framework it doesn't accept it, because nobody signed my cert.
Is there a way to solve this somehow? I suspect if I take the system wide cacert file (which is used by java) and my truststore, and then I merge them with keytool, it will solve this, but this is not the best way - it would be more sane if I could pack my self signed certs next to the application.
I had the same problem for some reason my own trust store wouldn't be recognized so I ended up adding my certificate to the default keystore (${java.home}/lib/security/cacerts). You can use this command to do this (BTW cacerts default password is changeit):
keytool -v -importkeystore -srckeystore alice.p12 -srcstoretype PKCS12 -destkeystore "c:\Program Files\Java\jre1.8.0_71\lib\security\cacerts" -deststoretype JKS
Then you need to have the trustManager and the key manager defined. The trustManager points to the trust store and the keyManager to your certificate.
play.ws.ssl {
trustManager = {
stores = [
{
path: ${java.home}/lib/security/cacerts
}
]
}
keyManager = {
stores = [
{
type: "PKCS12",
path: "/Users/work/Documents/path/to/certificate/certificate.p12",
password: "pass"
}
]
}
}
That error means Play can't find the stores. Is the path correct?
I had the same error message: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty caused by empty store. According to Key store docs there could be password field in the configuration but it was ignored therefore certificates were not read from the store. I had to use PEM format or you can include certificates in config see Configure store. The password field is added/put back in commit #e867e729. I'm on Play 2.6 so I couldn't test it.
I had to enable SSL over Active Directory server, to do that I followed each and every steps mentioned here: http://www.linuxmail.info/enable-ldap-ssl-active-directory/
Now I am not sure if SSL is really enabled properly?
On server itself if I run ldp, I think I can connect on 636 port. However on my system I don't see SSL option on ldp client?
I've two other LDAP clients (Softerra LDAP Browser and Apache Directory Studio) but I am not able to connect using ldaps (on 636 port). I guess I'll need to import certificate used in AD server so these tools can trust that self sign certificate which I used on AD server.
Using Java code, I've added certificate into cacerts (got certificate using steps mentioned here: http://www.linuxmail.info/export-ssl-certificate-windows-2003/), however I still can't connect to AD using SSL.
I tried SSL as well as TSL:
TLS:
// got LdapContext using ldap (not with ldaps)
StartTlsResponse tls = (StartTlsResponse)ctx.extendedOperation(new StartTlsRequest());
It gives following exception:
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
SSL:
String ldapURL = "ldaps://<domain-name>:636";
String keystore = "C:/Oracle/Middleware/jdk160_24/jre/lib/security/cacerts";
System.setProperty("javax.net.ssl.trustStore",keystore);
env.put(Context.SECURITY_PROTOCOL,"ssl");
// other properties are set in env
LdapContext ctx = new InitialLdapContext(env, null);
It gives following exception:
javax.naming.CommunicationException: <domain-name>:636 [Root exception is java.net.ConnectException: Connection timed out: connect]
Can anyone please suggest where I am wrong?
Thanks.
This one was fixed.
I was using wrong (rather incomplete) command to import certificate.
I was using:
keytool -import -alias mycert -keystore cacerts -file d:\mycert.cer
When I used follwing:
keytool -import -noprompt -trustcacerts -alias mycert -file c:/mycert.cer -keystore C:/Oracle/Middleware/jdk160_24/jre/lib/security/cacerts -storepass changeit
And it started working.
If you can't get TLS to work, it is unlikely that SSL will work. Are you sure that you got the right certificate and configured the keystore correctly? Based on the SSLHandshakeException when trying to use TLS, it would seem that may not be set up correctly.
Check out this SO answer for some tips on how to verify that your keystore is correctly set up: https://stackoverflow.com/a/9619478/1792088
I'm creating a Java client program that will be sending sensitive information to a Tomcat server. So I need to use SSL Connection so information will be encrypted.
I need to use self-signed untrusted certificate but having problems making connection from java client.
I have successfully setup Tomcat 5.5 to use SSL and tested it through Firefox, which displays warning of self-signed certificate.
I followed the Tomcat 5.5 SSL setup and they mentioned to create a keystore:
keytool -genkey -alias tomcat -keyalg RSA
Then I did an export of the above:
keytool -export -keystore .keystore -alias tomcat -file localhost.cer
Then I did an import of the above certificate into client machine:
keytool -import -alias tomcat -file localhost.cer -keystore "C:\Program Files"\Java\jdk1.6.0_17\jre\lib\security\cacerts"
But when running client I get:
Exception in thread "main" 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
This is the client code:
URL url = new URL("https://localhost:8443");
HttpsURLConnection conn = (HttpsURLConnection)url.openConnection();
conn.setSSLSocketFactory(sslsocketfactory);
InputStream inputstream = conn.getInputStream();
Now I just started playing with these certificates today and I'm new to keystores, so please be patient.
Can someone please explain how to export and import the certificate created in Tomcat to client machine?
Thank you.
Atlassian has good instructions on how to fix this.
http://confluence.atlassian.com/display/JIRA/Connecting+to+SSL+services
Another approach is to install less unforgiving certificate validators, but that should only be done as a last resort.
Use Apache HTTP Cleint jar and follow this SSL Guide.
EasySSLProtocolSocketFactory can be used to create SSL connections that allow the target server to authenticate with a self-signed certificate.
I think you should input password using "changeit".
