javapns sends notification but i receive anything - notifications

Question

I can send notification without any error but I don't get anything on my device. I tried a lot of solutions and I don't know what else I can do.
The certificat and token works in PHP...
Configuration : Java 1.8, Tomcat 7, Javapns 2.2
Thanks
Code
BasicConfigurator.configure();
URL res = getClass().getClassLoader().getResource("KeyNotification/certificat.p12");
File f = new File(res.getFile());
List<PushedNotification> notifications = Push.combined("message", 10, "", f.getAbsolutePath(), "password", false, token);
for (PushedNotification notification : notifications) {
if (notification.isSuccessful()) {
System.out.println("Push notification sent successfully to: " + notification.getDevice().getToken());
} else {
String invalidToken = notification.getDevice().getToken();
Exception theProblem = notification.getException();
theProblem.printStackTrace();
/* If the problem was an error-response packet returned by Apple, get it */
ResponsePacket theErrorResponse = notification.getResponse();
if (theErrorResponse != null) {
System.out.println(theErrorResponse.getMessage());
}
}
}

I solved my problem , the certificate was not compatible !
The command line to create the certificate (aps_development.pem is downloaded from Apple, myprivatekey.p12 is exported from my app private key in the "Keychain Access") :
openssl x509 -in aps_development.cer -inform DER -out aps_development.pem -outform PEM
openssl pkcs12 -nocerts -in myprivatekey.p12 -out myprivatekey.pem
openssl pkcs12 -export -inkey myprivatekey.pem -in aps_development.pem -out cert_dev.p12
