How to disable SSL Verification in Spring Vault (Spring Vault Core - version: 2.3.1)

I am getting below exception:
Cannot login using org.springframework.web.client.ResourceAccessException: I/O error on POST request for "https://<kmaas_domain>:443/v1/auth/aws/login": PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target; nested exception is javax.net.ssl.SSLHandshakeException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

I am using VaultTemplate to acquire the Token from Kmaas (implementation on HCP Vault) to get secrets. How can I disable this SSL check? Python based Boto library does have this option as
requests.request(request_type, RESOURCE_PATH, headers={'X-Vault-Token': client_token}, **verify=False**, data=PAYLOAD)
but I can't find any such option in Java

Gmail API: Unable to find valid certification path to requested target

I am using GMail API to get code, but I am getting below issue mostly every time:
java.lang.RuntimeException: 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
Can someone please help me on this?

WSO2 ESB - Sending Emails

I have a simple e-mail alert use case.
Have done the basic configurations in axis2.xml, and when i try the proxy the following exception shows up.
javax.mail.MessagingException: Can't send command to SMTP host;
nested exception 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

at com.sun.mail.smtp.SMTPTransport.sendCommand(SMTPTransport.java:1408)
The issue, I believe is I'm missing the following line of code in the configuration of ESB.
Session session = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("aaa", "bbb#0089");
}
});
I have tried, tested successfully with a small java email app and javamailAPI including this authentication.
How can I do the same configuration in the <ESB_HOME>/repository/conf/axis2/axis2.xml
Any suggestions will be very much helpful. ESB 4.9.0
Thanks in advance.

This seems to be because the required certificate is not available in the client trust store. Try again after importing it. To import the certificate to the trust store you can refer this blog.

ServiceRequestException: The request failed with Microsoft Exchange Server using Java

So I am trying to send a hello world email using the ews-java-api.
My code looks like:
ExchangeService exchangeWebService = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
exchangeWebService.setCredentials(new WebCredentials(username , password, localPcDomain));
exchangeWebService.setUrl(new URI(companyExchangeURL));
EmailMessage msg= new EmailMessage(exchangeWebService);
msg.setSubject("Hello world!");
msg.setBody(MessageBody.getMessageBodyFromText("Sent using the EWS Java API."));
msg.getToRecipients().add(testEmail);
msg.send();
But I get the following exception:
microsoft.exchange.webservices.data.ServiceRequestException: The request failed. The request failed. sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
Caused by: microsoft.exchange.webservices.data.ServiceRequestException: The request failed. 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
Any ideas on what I need to do? I have tried using autodiscover but it always seems to fail.

From the error it sounds like it may be an SSL issue (invalid certificate, untrusted certificate, etc.). A quick test would be to go to the OWA url for that server and see if your browser gives a warning or error about the SSL cert.

SSL keys and client auth in Java

I am connecting to a webservice SSL client auth, I set up the keystore by:
System.getProperties().setProperty("javax.net.ssl.keyStore",
"d:/banking/BankClient/classes/xxcompany/bank/certificate/keystore.jks");
System.getProperties().setProperty("javax.net.ssl.keyStorePassword","password");
When calling the webservice:
GetAccountBalanceResponse resp = services.getAccountBalance(request);
I get a following error

The keystore containes the private certificate for the client, the certificate is valid and works fine when used in the browser. How should I fix it?
Many thanks.

This error occurs when the CA which signed the server cert is either not one of the well know CAs or the public certificate of the CA is not in the trust store of the client. To get around this you will have to add the public certificate of the CA to the trust store of the client.
