Error while consuming secure SOAP base web service in JAVA

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.

SSL Issues with Java PKIX / validator.ValidatorException despite proxy

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 ...

LDAPS configuration for IBM MobileFirst v8 Login Authenticator

I tried to move from ldap to ldaps for Login authenticator.
In adapter.xml
<property name="ldapURL" defaultValue="ldap://10.10.10.10:10636" displayName="The LDAP Server URL"/>
In LoginAuthenticator class
env.put(Context.SECURITY_PROTOCOL, "ssl");
I get the following error.
javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
I do not know, where I need to put my keystore to hit in ldaps protocol. Can you please help me?
I tried putting it in the following path with server.xml configurations, but no luck.
E:\MobileFirst-8.0.0.0\mfp-server\usr\servers\mfp\resources\security
<sslDefault sslRef="mySSLSettings" />
<ssl id="mySSLSettings" keyStoreRef="LDAPKeyStore" clientAuthentication="true" />
<keyStore id="LDAPKeyStore" location="serverssl.ks" type="JKS" password="secret" />

As pointed out by marabu, if you add the CA certificates of your LDAP server to Liberty's trust store, it might solve your problem.
Where you need to add depends on how you have configured your trust store.
Going by the ssl configuration snippet you have pasted and assuming you have not defined the truststore via jvm.options or added it in MobileFoundation's keystore in MobileFoundation console, your serverssl.ks would act as both keystore as well as trust store.
So if you add the CA certificates of your LDAP server to serverssl.ks and restart the server, it should work I feel.
You can add a CA certificate to your keystore by executing this command,
keytool -importcert -keystore serverssl.ks -alias <your_alias> -file <yourcacert.pem>

You wonder about the keystore, but the error message is about your truststore. The backend presents its (presumably self-signed certificate or a self-owned CA) certificate to your adapter during the SSL handshake. Your adapter tries to walk the chain of trust by looking for the issuers certificate recursively in your truststore.
Either you didn't import the backend certificate chain into your truststore or your adapter isn't using the truststore you configured.

issues in connecting to AD server over SSL?

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

SSL Connection from Java client

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".
