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

Question

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 ;

}
