Jira OAuth - Unable to create application link

Question

I am trying to create an application which uses jira for authentication. I am using Jira Rest api for the same. In the documentation it says to use the same public key and consumer-key to create application link as given in the doc. This works fine, and I am able to create access-token. But in java code as mentioned in this, I am not sure what should be given for private_key. I tried two methods-

Generated a random private key using rsa and provided it in place of private_key which didn't work. It gave exception telling length too long. I tried for 2048, 1024, 512, 256 and 128 bits. Everything gave same error.

Application link:

Consumer-key: hardcoded-consumer

Consumer Name: hardcoded-consumer

Public Key: MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEAxZDzGUGk6rElyPm0iOua0lWg84nOlhQN1gmTFTIu5WFyQFHZF6OA4HX7xATttQZ6N21yKMakuNdRvEudyN/coUqe89r3Ae+rkEIn4tCxGpJWX205xVF3Cgsn8ICj6dLUFQPiWXouoZ7HG0sPKhCLXXOvUXmekivtyx4bxVFD9Zy4SQ7IHTx0V0pZYGc6r1gF0LqRmGVQDaQSbivigH4mlVwoAO9Tfccf+V00hYuSvntU+B1ZygMw2rAFLezJmnftTxPuehqWu9xS5NVsPsWgBL7LOi3oY8lhzOYjbMKDWM6zUtpOmWJA52cVJW6zwxCxE28/592IARxlJcq14tjwYwIDAQAB

Generated private and public key pair and provided the same in application link and in code respectively. But in this case, I am unable to create access token. It is giving -

Application link:

Consumer-key: hardcoded-consumer

Consumer Name: hardcoded-consumer

Public Key: MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC0YjCwIfYoprq/FQO6lb3asXrx LlJFuCvtinTF5p0GxvQGu5O3gYytUvtC2JlYzypSRjVxwxrsuRcP3e641SdASwfr mzyvIgP08N4S0IFzEURkV1wp/IpH7kH41EtbmUmrXSwfNZsnQRE5SYSOhh+LcK2w yQkdgcMv11l4KoBkcwIDAQAB

Can someone explain me what should be done? Am I missing something here? And also what is the difference between shared key, consumer key and public key?

Thanks in advance

If I remember correctly you should use private key in your client application to sign requests. Of course you need a pair of private and public keys that match. Unfortunately I don't know Java api since I used .NET — Robert
Tnx for the reply @Robert . I have fixed the issue somehow and have posted the answer — DivyaMenon

The exception occurs due to ending with "/" in JIRA base URL (caused by net.oauth.OAuthProblemException: signature_invalid).

The correct request is:

java -jar rest-oauth-client-1.0.one-jar.jar requestToken https://jira_base_server_url http://your_redirctedUrl
