sun.security.validator.ValidatorException: PKIX path building failed (with production server) about javapns HOT 15 CLOSED

The error seems pretty clear. Verify that the files exist where the java app is 
expecting them.

What logging do you get when you use the flags indicated on the wiki page:
http://code.google.com/p/javapns/wiki/Tips

The file is where it looks for it.  And I exported it to p12 correctly.  How do 
i check the logs?

This is happening when i go to send the notification not when initializing. 

"How do i check the logs?"

uh... You should do some research on implementing log4j, once that is worked 
out, go visit the link I mentioned earlier.

yanchek99, were you able to get your code working with the production server?  
May we close this issue?

Issue suspected of being caused by invalid certificate chain for selected 
server.

Closing issue as no feedback was received since issue was reported.  
Please feel free to re-open if the issue is still valid.

i am getting same issue on my tomcat server..can we discuss this issue here...i 
had hard time to get resolve this..Thanks in advance

This is an issue with the certificate chain which is either invalid, or is not 
built for the specific Apple service you are using (sandbox or production).  I 
strongly suggest you follow very precisely the procedure described in the 
"Preparing APNS certificates" wiki page on this site.

If you are still having an issue with this, please follow the troubleshooting 
steps provided in the "Troubleshooting" wiki page and copy-paste all results in 
this issue report so we can investigate further.

if i run this sample program from outside server from commandline lets say i 
get push notification on my iphone but when i run this programm from our server 
it is giving me exception.i'm using same certificate that means certificate 
doesn't seems any problem may be im missing any configuration. my server is 
tomcat.

Please advice.

Thanks.

If you can push notifications successfully from the command line, but get an 
exception with the same keystore file from within Tomcat, maybe there is 
something wrong with the way the keystore file is read from Tomcat?  Could you 
post a complete stack trace of the exception you are getting, as well as the 
code you are using in Tomcat to push a notification?  Thank you!

exception file is attached...and code also..same code im calling in tomcat 
server..
Thanks

You are using an old version of JavaPNS (1.6 I believe?).  Please make sure you 
use version 2.0, as tons of fixes have been made since 1.6...

Hi,
Thanks for replying..previously i was trying 2.0 beta version it didn't work 
for me then i switched back to 1.6 neither it does but now i tried 2.0 latest 
version and guess what...it is working like a charm..
Thanks a lot.

Outstanding, thank you!
