UPDATE 1/26/2015 -- It appears the most recent JRE/JDK for Java 8 (update >= 31) and JRE/JDK for Java 7 now include the Godaddy G2 CA server in the default trust store. If possible, it's urged you upgrade your JRE/JDK to the latest Java 8 update to resolve this issue.
UPDATE 11/29/2014 -- This is still a problem, and Godaddy appears to not care nor will do anything about it. There is a blog post here by Godaddy VP of Security Products from several months ago saying a fix was on it's way and provided a temporary work-around, but as-of today nothing has changed. It is important to note that Godaddy's G2 CA server has been around for a minimum of 5 years, and in that time Godaddy has not taken the proper steps to resolve this known issue. The work-around provided is just that, a work-around, not a solution. Users of 3rd party services have zero control over how the cert is installed on the server.
It seems users should avoid purchasing Godaddy SSL certs until they get serious about being a CA.
Here is their SSL team's contact info if you feel inclined to call:

UPDATE 9/17/2014 -- This is still a problem, and Godaddy appears to not care nor will do anything about it. Come November when Google deprecates all SHA-1 certs, this will become a major issue. I highly recommend anyone who can contact Godaddy and point them here.

tl;dr; - final update with current solution/workaround at the bottom of this post (it is a GoDaddy problem and there is a workaround until they fix it)
I have a mail server that I'm attempting to send mail through from my Java app. I can sent on port 25 successfully so I know code works and all, but 25 is not encrypted session. I need to use TLS on port 587 which requires an SSL cert. I have a valid SSL Cert on the server that is signed by GoDaddy G2 CA and has been in place for a while now (no problems).
My issue, is I'm getting the famed PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target error message when trying to connect and send mail on 587.
From my understanding of many SO links as well as normal google-fu, this is usually caused when Java doesn't trust the cert or CA -- as is common for a self-signed cert. I've used several of the online SSL Cert checkers to make sure the chain is valid, etc. All appears to be normal... but java will not use the cert automatically.
I am aware there is a class file somewhere from Sun that will download and setup the cert in the local keystore so java will trust it... but this is not only impractical for an app that will be deployed to multiple systems, but is just silly for a Godaddy signed cert.
What's going on? How can I make java use the valid cert on the server without having to make java accept all certs?
EDIT: I just looked in my windows Java Control Panel (default install of jdk 7) and sure enough, under Signer CA the Issued By: The Go Daddy Group, Inc. Go Daddy Class 2 Certification Authority is listed... so what gives? My cert is a Godaddy cert...
UPDATE --
Here's the cert chain as-seen from openssl command recommended in comments:

CONNECTED(00000003)
depth=2 C = US, ST = Arizona, L = Scottsdale, O = "GoDaddy.com, Inc.", CN = Go Daddy Root Certificate Authority - G2

Looks ok to me I think...
UPDATE 2 --
Ok, thanks to @Bruno I was able to determine my chain was messed up -- I re-keyed the server and now my chain appears as such:

CONNECTED(00000003)

Which looks better than before. -- Java still throws the same exception about the cert path, etc. So it appears that the G2 cert chain is not, by default, trusted yet in java 7's default keystore.
FINAL UPDATE FOR COMPLETENESS @ 1/14/2014
Just as an update - This is indeed a GoDaddy problem (I've had lengthy support emails with them). They have 2 CA servers, one called Class 2 CA and the other called G2 CA. Their Class 2 CA signs all SHA-1 certificates, while the G2 CA signs all their SHA-2 certificates. This is where the problem lies - GoDaddy has not added their newer G2 CA server to the default java truststore - causing default java installations to not trust it's authority, and hence, does not trust your chained certificate. The work-around until GoDaddy adds the G2 CA server to the default truststore is to simply rekey your cert using SHA-1 as-to get a cert signed by the Class 2 CA server. Rekeying is free for GoDaddy customers until your cert expires (obviously).

My initial post/question was regarding why my chain was not working. It became obvious I had a bad setup (which was quickly fixed with some advice from @Bruno and others - thanks). However, when my corrected chain still did not work with Java, it became apparent there was a much bigger problem lurking. It took a while, but the problem is actually with GoDaddy.
This actually is indeed a GoDaddy problem (I've had lengthy support emails with them).
They have 2 CA servers, one called Class 2 CA and the other called G2 CA. Their Class 2 CA signs all SHA-1 certificates, while the G2 CA signs all their SHA-2 certificates.
This is where the problem lies - GoDaddy has not added their newer G2 CA server to the default Java truststore/keystore - causing default Java installations to not trust it's authority, and hence, does not trust your chained certificate.
The work-around until GoDaddy adds the G2 CA server to the default truststore/keystore is to simply rekey your cert using SHA-1 as-to get a cert signed by the Class 2 CA server. Rekeying is free for GoDaddy customers until your cert expires (obviously).
Once you have a SHA-1 cert signed by the Class 2 CA server, your trust chain should work as expected and no custom truststore/keystore imports and/or setup is required.
It does not make me happy that I must use a "weaker" cert in order to get it to work properly, and discussions with GoDaddy via email support thus far have indicated they have no current plans to add the G2 CA server to the default truststore/keystore. I guess until they do add it, make sure you get a SHA-1 Class 2 CA server signed cert if you plan to work with Java.
回答2:
Mr. Fixer and Wayne Thayer's answers have been downvoted, but they are actually advocating the correct work-arounds. In fact, Wayne Thayer leads GoDaddy's SSL business, so he probably knows. You should install the "GoDaddy G1 to G2 Cross" certificate in your certificate chain along with the intermediate certificate.
Downgrading to SHA1 is not an ideal option since it's being deprecated and will cause you more work in the future. Fortunately, GoDaddy has provided a crossover certificate that solves this problem. They posted instructions, which Wayne has duplicated, and they're buried in the comments here.
I have personally tested this solution with a SHA2 cert, and it works well. It's a far superior solution vs. re-keying and downgrading to SHA1. When SHA2 becomes required, this option won't be available anyway, and there might still be Java toolchains out there without the new certificate.
According to GoDaddy support, as of July 2014, the correct root certificate was included in recent versions of Java 8, and in September 2014, Wayne Thayer of GoDaddy also said that the certificate "is scheduled to be added to Java in the next few months". I have checked the cacerts file in Java 8 for Mac OS downloaded from here, and it does indeed contain the SHA2 root certificate.
So instead of your chain looking like this:
- Go Daddy Root Certificate Authority – G2: (SHA-2) – Hash 47 BE AB C9 22 EA E8 0E 78 78 34 62 A7 9F 45 C2 54 FD E6 8B. This is the root certificate that’s built into some systems (e.g. Chrome). SnakeDoc claims that "it's not built into Java, Windows CE, Microsoft Exchange, and more platforms".
- Go Daddy Secure Certificate Authority – G2: (SHA-2) – Hash 27 AC 93 69 FA F2 52 07 BB 26 27 CE FA CC BE 4E F9 C3 19 B8
- Your SHA2 certificate
It should look like this:
- Go Daddy Class 2 Certification Authority: (SHA-1) – Hash 27 96 BA E6 3F 18 01 E2 77 26 1B A0 D7 77 70 02 8F 20 EE E4. This is the old root certificate that’s built into most systems, including java.
- Go Daddy Root Certificate Authority – G2: (SHA-2) – Hash 34 0B 28 80 F4 46 FC C0 4E 59 ED 33 F5 2B 3D 08 D6 24 29 64. This is the so-called “GoDaddy G1 to G2 Cross Certificate”.
- Go Daddy Secure Certificate Authority – G2: (SHA-2) – Hash 27 AC 93 69 FA F2 52 07 BB 26 27 CE FA CC BE 4E F9 C3 19 B8
- Your SHA-2 Certificate

回答3:
To get Godaddy certificates to work in Java with SHA2 you will need to use their cross certificate in your chain to chain the G2(SHA2) root to the G1(SHA1) root until Java decides to update their repository. The Cross Certificate bundle can be downloaded here:
https://certs.godaddy.com/anonymous/repository.pki
GoDaddy Certificate Bundles - G2 With Cross to G1, includes Root
[gd_bundle-g2-g1.crt][1]
回答4:
Mr. Fixer is right. Install the "GoDaddy G1 to G2 Cross" certificate in your certificate bundle file along with the intermediate certificate. This allows GoDaddy SHA-2 certificates to be trusted by any client that recognizes the SHA-1 roots including Java. You can get this file from https://certs.godaddy.com/repository Once this is installed, Java will build a certificate chain from your certificate to the "GoDaddy Secure Server Certificate (Intermediate Certificate)" to the "GoDaddy G1 to G2 Cross Certificate" to the GoDaddy SHA-1 root. You can also find a bundle file containing the cross certificate in our repository. One last note on this option: The signatures on root certificates aren't checked so even though you're relying on a SHA-1 root, this is just as secure as a full SHA-2 certificate chain.

Following comments and the output of openssl s_client -connect the.server.name:587 -starttls smtp.
In a certificate chain, cert n should be issued by cert n+1 in the list: the issuer (i) of cert n should be the subject (s) of cert n+1.

Here, cert 0 is issued by cert 1 (fine), cert 1 is issued by cert 2 (fine), cert 2 is self-signed (also fine, this is the root CA).
However, cert 2 isn't issued by cert 3. Cert 3 is misplaced (and probably the same as cert 1). This is likely to cause problems, since this makes the chain invalid.
You should at least remove cert 3 from your configuration. In addition, you can also remove cert 2, since having root CAs isn't necessary (it's up to the client to know it anyway).

It sounds like your mail server is not signed by Go Daddy Class 2 Certification Authority, but is actually signed by one of their intermediate certificate authorities. You will need to verify this for yourself. Assuming this is the case...
In theory, your software should work - since the intermediate certificate is signed by the class 2 authority and you have the class 2 authority in the default JDK certificate store. However, I have found that it just does not work unless you also add the intermediate certificate to your certificate store. Here is a link to a blog post describing a similar experience:
http://drcs.ca/blog/adding-godaddy-intermediate-certificates-to-java-jdk/
Here is a direct link to more GoDaddy intermediate certificates:
https://certs.godaddy.com/anonymous/repository.pki
I cannot advise on exactly which certificate you must add - it depends on which CA is used in your mail server.
[update]
is there a way to do this programmically?
Maybe. Depends on what you want to do. I have used the java.security.KeyStore class to automatically update a private keystore directly from Java code without using keytool. It is conceptually simple - load the keystore from a file, read the new certificate, add it to the keystore and then write out the keystore to new file. However it takes a while to get the details right and it may not be worth the trouble just to import a single certificate.
Still, it is interesting to try. Checkout KeyStore JavaDoc and read up on the load, store and setCertificateEntry methods.
回答7:
In the "Java Control Panel" I just added the GD Root Certificate to the "Secure Site CA" and I no longer have the cert error when using Java. The cert I added was:
Go Daddy Class 2 Certification Authority Root Certificate - G2
回答8:
if you import de GoDady G2 bundle into the java keystore solves the problem:
export JAVA_HOME=/usr/lib/jvm/java-8-oracle/
wget https://certs.godaddy.com/repository/gd_bundle-g2.crt
$JAVA_HOME/bin/keytool -import -alias root -file ./gd_bundle-g2.crt -storepass changeit -trustcacerts -keystore $JAVA_HOME/jre/lib/security/cacerts
回答9:
Update - this "solution" is no longer valid (see my above accepted answer) - keeping this answer because it did help alleviate the problem so long as the side-effects are tolerable.
Ok, I may have found a work-around for my case.
props.put("mail.smtp.ssl.trust", "smtp.somecompany.com");
I added this to my Session construction, and now it works. This is a work-around, not a fix imho since I still do not know why my Godaddy SSL cert is not default trusted... it is not a self-signed cert.
Anyone please feel free to chime in as I'd really like to understand this problem.

Here is what you can try. Add the GoDaddy root and intermediate certificates to trust manager at run time. i.e start if the application.
