How to delete bucket policy using Java SDK ecs-object-client-java

Hello,

I am creating Bucket policies in my application using following java code snippet:

(I am using EMC Java SDK ecs-object-client-java)

>>>

List < BucketPolicyStatement > stmts = new ArrayList <>();
 
stmts . add ( new BucketPolicyStatement ()
. withSid ( "Grant permission to " + userId + " for objects" )
. withEffect ( Effect . Allow )
. withPrincipal ( userId )
. withResource ( bucketName + "/*" )
. withActions ( BucketPolicyAction . GetObject ,
BucketPolicyAction . GetObjectVersion ,
BucketPolicyAction . GetObjectAcl ,
BucketPolicyAction . GetObjectVersionAcl
)
);
stmts . add ( new BucketPolicyStatement ()
. withSid ( "Grant permission to " + userId + " for bucket" )
. withEffect ( Effect . Allow )
. withPrincipal ( userId )
. withResource ( bucketName )
. withActions ( BucketPolicyAction . ListBucket ,
BucketPolicyAction . ListBucketVersions ,
BucketPolicyAction . GetLifecycleConfiguration ,
BucketPolicyAction . GetBucketAcl ,
BucketPolicyAction . GetBucketVersioning ,
BucketPolicyAction . GetBucketPolicy
)
);
 
BucketPolicy bucketPolicy = new BucketPolicy ()
. withVersion ( "2012-10-17" )
. withId ( "new-policy-1" )
. withStatements ( stmts );
 
s3Client . setBucketPolicy ( bucketName , bucketPolicy );

<<<

Everything is working fine. But my question is how do I DELETE (remove) the Bucket policy programatically once it is set as above.

Any help / pointer would be highly appreciated. 

Thanks

    Hello Dell-Sam L,

    Thank you for the quick response, but my question was about deleting the Bucket policy using S3 object client interface. Anyway mean while I figured out how to do it. I extended the ""S3JerseyClient" object in ecs-object-client-java SDK as follows. It works just fine now:

    public class ECSs3Client extends S3JerseyClient {

    public ECSs3Client ( S3Config s3Config ) {
    super ( s3Config );
    }
     
    public void deleteBucketPolicy ( String bucketName ) {

    try {
    executeAndClose ( client , new GenericBucketRequest ( Method . DELETE , bucketName , "policy" ));
    return ;
    } catch ( S3Exception e ) {
    switch ( e . getHttpCode ()) {
    case RestUtil . STATUS_REDIRECT :
    return ;
    // case RestUtil.STATUS_UNAUTHORIZED:
    // return;
    // case RestUtil.STATUS_NOT_FOUND:
    // return;
    default:
    throw e ;
    }
    }
    }

    }
