I tested the server by using a plain javamail app with no extra settings and it worked fine.
But using Seams mail-tags the Exception occurs.
- Is there a way to disable SSL?
I realy don't need SSL.
I found these properties in a forum
mail.smtp.ssl.trust="*"
mail.smtp.starttls.enable="true"
How could I pass them the properties above through seam framework down to javamail ?
The error you're getting means that one of the certificates (presumably the server's certificate) isn't trusted by your JavaMail client. Since you seem to be using STARTTLS, you're effectively using SSL/TLS.
You could perhaps try something like mail.smtp.starttls.enable="false" if you don't want to use SSL/TLS at all, although some SMTP servers will force you to use it (either SSL/TLS on connection or via STARTTLS) to proceed any further.
Alternatively, if you change your mind and want/need to use SSL, make sure your trust store on the client side contains a trust anchor (CA certificate) that can be used to verify your server certificate. (Note that the mail.smtp.ssl.checkserveridentity default to false is insecure, so you'd want to change that to true, and not use mail.smtp.ssl.trust="*".)
According to Seam reference manual and Seam forum you should be able to disable TLS and SSL directly in your components.xml configuration:
<mail:mail-session debug="true" tls="false" ssl="false" ... />

I have a local environment with WebLogic 10.3.4 and and .ear app deployed on it. This app must communicate with external services via REST APIs. These external services are exposed in https and use wildcard certificates.
I receive the following exceptions when I try to connect to to one of these services.
org.springframework.web.client.ResourceAccessException: I/O error on POST request for "https://dds-service.domain.com" General SSLEngine problem; nested exception is javax.net.ssl.SSLHandshakeException: General SSLEngine problem [...]
[...] Caused by: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target [...]
[...] Caused by: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
So what I tried in first instance was to open the same url the app tries to connect to in my browser, download its wildcard certificate (.cer Base64 encoded) and with key tool import it into the jvm's trust store that WebLogic loads and looks up when trying to validate a cert. I am sure is the correct one because i imported other certificates that caused the same error and also because of this log
<Loading trusted certificates from the jks keystore file C:\WEBLOG~1\wls\JROCKI~1.1-3\jre\lib\security\cacerts.>
At this point, I suppose the problem is related to the way I import the wildcard certificate in WebLogic. I tried to look for different ways to do it but, like this one, require a .pfx file that is not currently available to me at the moment.
Do I need a .pfx to solve this or is there another way?
If someone will ever have the same problem, here is the solution i found: it appears that WLS 10.3.x has issues in trusting certificates wth keys longer than 128 bits, this is what caused the problem in first instance. That said, 2 actions solved my problem
-DUseSunHttpHandler=true added as a VM argument in the setDomainEnv script
Enable JSSE SSL via WLS adminn console (Environment > Servers > server name > Configuration > SSL > Advanced > check the JSSE SSL box)
Click Save, and restart WLS server.
I have an Apache web server fronting a Tomcat 8 web server that is running my website, and I'm switching the top-level domain from my.website.ie to my.website.com. I have some code that runs in response to a particular request that generates a PDF. That code fetches an image (using a URL) which is served from the same web server e.g.
Image.getInstance(new URL("https://my.website.com/img/myimage.png"))
In addition to the domain change, I'm also changing my SSL certificate provider to LetsEncrypt (free SSL certs). My development website at the new .com domain is running and the certificate is valid and does not expire for a number of months.
I have another development server running on a separate machine that is still using the .ie domain. The Tomcat codebase running on both of these servers are identical right now. They are both trying to fetch the image at the URL shown above in that particular piece of code.
On the .ie server, the request that generates the PDF works correctly, without any problems fetching the image. On the .com server, the request fails with this 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
...
Caused by: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
...
Caused by: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
My understanding of this error is that the certificate at the target URL is not trusted (e.g. self-signed), but that is not true in this case. Also, both of the servers are hitting the same URL for the image, so why is one server trusting the certificate and the other not?
I haven't made any additional configuration changes on the .ie server that I haven't made on the .com server (with respect to setting up the new certificate), so is there some other (mis)configuration that I haven't considered?
Not trusted means the used CA is not trusted by the software.
Self-signed certificates are never trusted.
Java has it's own trust store (only on Linux the system trust store is used AFAIR?). If the CA certificate is newer than the used Java version it may happen that Java does not trust the CA. Conclusion: Update your Java.
According to this Stackoverflow answer you need at least Java 8u101 for Let's Encrypt support:
Does Java support Let's Encrypt certificates?
The error says that the chain doesn't lead to a root certificate that is trusted. Trusted CA root certificates are stored in Java's root keystore where the root certificate issued by Let's Encrypt is obviously missing.
You can add the root certificate manually to the store or check if newer versions of Java already contain the certificate.
I have a web application using java 7 and tomcat 6 on ubuntu 12.04. It uses apache cxf to make REST calls to a web service on a different server over https. It has been working fine until about 11am today. Then for each REST call whether GET or POST, I receive
javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated
Caused by: 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 errors in catalina.out.
The certificate is in the
jdk/jre/lib/security/cacerts
and does not expire until 2018. When I restart tomcat the program runs fine.
Any idea what would trigger this?
Thanks in advance
Randy
If you are entirely certain that this is not a validity period problem with the service's certificate, here are some more situations to check for:
The certificate on the service side was changed so the one in cacerts is now not doing anything
The certificate you installed was the a system's certificate and you are now connecting to a different node due to load balancing (if so, you would need an intermediate or CA cert)
The service requires Mutual TLS (aka 2-way SSL) and the certificate on your side is now missing or invalid
A host name has changed such that the certificate(s) are no longer valid
Some software or configuration file has changed and now the client and service do not have SSL/TLS versions in common.
I'm using novell ldap api and I must use ssl connection but I'm searching for a way in which the client not verify the certificate when connection starts...I get the follow 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'm try to reproduce the behavior like when I open a web page in https and browser asks me if I want to accept the certificate...
I didn't find any method to do this with novell ldap api and I'm wondering if it is possibile to do in pure java programmatic way. Thanks

I have PKCS#12 keystore that I've sucessfully imported in my browser for accessing a server that needs 2-way SSL authentication. Works perfectly reaching any https URL there.
However, I'm unable to access an URL in the same server, and from the same host when using Axis 1.4. The given Axis faultString 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
My javax.net.ssl.{keyStore,keyStorePassword,keyStoreType} properties seem to be set up fine.
How can I resolve this?
I came across a simpler answer if all you want is for your client to be able to call the SSL web service and ignore SSL certificate errors. (Of course you would NOT do this in production!, but it sure is handy for testing.)
Just put this statement before you invoke any web services:
System.setProperty("axis.socketSecureFactory",
"org.apache.axis.components.net.SunFakeTrustSocketFactory");
I found this at the Axis wiki.
Finally, importing the certificates into my own truststore, using Andreas Sterbenz's InstallCert, and setting the trustStore properties as indicated here did the trick!
