Hi,

 

I tried to get BoxDeveloperEditionAPIConnection using a stand alone java

 

String privateKey = new String(Files.readAllBytes(Paths.get(PRIVATE_KEY_FILE)));

JWTEncryptionPreferences encryptionPref = new JWTEncryptionPreferences();
encryptionPref.setPublicKeyID(PUBLIC_KEY_ID);
encryptionPref.setPrivateKey(privateKey);
encryptionPref.setPrivateKeyPassword(PRIVATE_KEY_PASSWORD);
encryptionPref.setEncryptionAlgorithm(EncryptionAlgorithm.RSA_SHA_256);

//It is a best practice to use an access token cache to prevent unneeded requests to Box for access tokens.
//For production applications it is recommended to use a distributed cache like Memcached or Redis, and to
//implement IAccessTokenCache to store and retrieve access tokens appropriately for your environment.
IAccessTokenCache accessTokenCache = new InMemoryLRUAccessTokenCache(MAX_CACHE_ENTRIES);

api = BoxDeveloperEditionAPIConnection.getAppUserConnection(USER_ID, CLIENT_ID,
CLIENT_SECRET, encryptionPref, accessTokenCache);

 

I am getting the below exception, Please help me if you come across this exception.

    Thank you for the quick help.

     

    I tried with the JCE but didn't work, with the link you provided I realised that i need to use JCE from IBM since I am using the IBM JRE for running.When I use the IBM JCE files it worked.

     

    Thanks

    I have set the required scope in for my box application. I am using the enterprise account to connect to.

    Yes I got this error too.

     

    If you set a breakpoint in your code and drill down, you can capture what goes across the wire.  I captured the call and put it in postman and ran it and got the real error.

     

    The solution was 's https://community.box.com/t5/Developer-Forum/Current-date-time-MUST-be-before-the-expiration-date-time-listed/m-p/17929#M392

    Hi Ken,

     

    Thanks for the solution, After troubleshooting with the postman, this is the response from the /token endpoint

    This app is not authorized by the enterprise admin.

    I am not able to see authorise button for this app, when I locate the app in admin console.

     

    Please advise, how to authorize the app.

     

    Thanks

    Chandra

    Yes, you're right.

     

    The enterprise admin has to go to admin console -> enterprise settings -> apps -> Authorize App.

     

    I don't think there's any way around this but to talk to your admin.

    I also got the same error when I tried with Postman

    Request

    URL: https://api.box.com/oauth2/token

    Method: POST

    Body: grant_type, client_id, client_secret, assertion

     

    Response: 400 Bad Request

    {
    "error": "invalid_grant",
    "error_description": "Current date/time MUST be before the expiration date/time listed in the 'exp' claim"
    }
