ios - Java APNS Certificate Error with "DerInputStream.getLength(): lengthTag=109, too big."

Question

When I try to using java APNS to send the push notification to iOS, I got this error message:

com.notnoop.exceptions.InvalidSSLConfig: java.io.IOException: DerInputStream.getLength(): lengthTag=109, too big.

I already try converting the certificate to Personal Information Exchange (.p12) also getting the same error. Anyone know to problem and how to resolve it?

Here are my java code:

ApnsService service =
    APNS.newService()
   .withCert("src/net/notification/ck.jks", "******")
   .withSandboxDestination()
   .build();

String payload = APNS.newPayload().alertBody(record.getSendMsg()).build();
String token = record.getToken();
service.push(token, payload);

Thanks.

Answer 1

This occurs because the system thinks you are trying to read a different type of keystore and not JKS. You will need to specify that the file is JKS or convert it to the other format.

I see that you have already tried converting to .p12. If you did this correctly, perhaps there is some other default format. I recommend finding out how to specify JKS instead.
