连接到邮件服务器时发生异常

Question

I got the following exception while connecting to Mail server from IBM WAS.

javax.mail.MessagingException: Could not convert socket to TLS; nested exception is: java.net.SocketException: java.security.PrivilegedActionException: java.io.FileNotFoundException: D:\Program Files (x86)\IBM\WebSphere\AppServer\jre\lib\security\cacerts (The system cannot find the path specified.)

My question is:

What is the certificate that I should import? Is it the mail server's certificate which needs to be imported into WAS? Should I ask the mail server admin to share the certificate?

Once I figure out which certificate, I plan to follow these instructions to import it: How to connect to a secure website using SSL in Java with a pkcs12 file?

Answer 1

That link is not the correct way to use mail sessions in WAS. Check this Websphere 7 javax.mail.MessagingException: SSLSocketFactory is null .

Try to use default SSL WebSphere configuration and Mail session resource. You will need to add your mail server certificate to the Trust store ( NodeDeaultTrustStore or CellDefaultTrustStore depending whether you use standalone or network deployment version).

It should be possible to get mail server cert using a browser, when you connect using https://mailserver:port / it should give you certificate which you could save locally and add to truststore. If you will have problems contact mail server admin.

PrivilegedActionException also suggest that you may have Java 2 security enabled. Check if it is enabled and if you really need it.
