Amazon S3 - List all the zip files recursively within S3 bucket using Java API -

i've s3 bucket on amazon , trying list of zip files located within folders under bucket recursively.

for e.g, zip files located shown below :

bucket1/${user1}/${date1}/abc.zip bucket1/${user2}/${date2}/xyz.zip bucket1/${user3}/${date3}/mno.zip  bucketname=bucket1 prefix=bucket1/ 

below code :

final amazons3 amazons3 = amazons3utils.getamazons3client(); final listobjectsrequest listobjectsrequest = new listobjectsrequest().withbucketname("bucket1")                                                                             .withprefix("bucket1/");  objectlisting current = amazons3.listobjects(listobjectsrequest); final list<s3objectsummary> keylist = current.getobjectsummaries();  while (current.istruncated())  {    keylist.addall(current.getobjectsummaries());    current = amazons3.listnextbatchofobjects(current); }  keylist.addall(current.getobjectsummaries()); for(s3objectsummary summary : keylist) {     system.out.println(summary.getkey()); } 

but empty list.

am doing wrong ? there way recursively list of zip files bucket ?

only thing can see getting connection s3 bucket.try following , may help

awscredentials credentials = new basicawscredentials(accesskeyid,secretaccesskey);         amazons3 s3client = new amazons3client(credentials);  objectlisting objects = s3client.listobjects(listobjectrequest);
