Hi, I’m trying to access S3 using jets3t library.
I just followed an sample code supported by AWS(here’s url)
here’s my simple code
import org.jets3t.service.S3Service;
import org.jets3t.service.S3ServiceException;
import org.jets3t.service.impl.rest.httpclient.RestS3Service;
import org.jets3t.service.model.S3Bucket;
import org.jets3t.service.security.AWSCredentials;
public class Test1 {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
String awsAccessKey = "******************";
String awsSecretKey = "*********************************";
System.out.println("0");
AWSCredentials awsCredentials = new AWSCredentials(awsAccessKey, awsSecretKey);
try{
S3Service s3Service = new RestS3Service(awsCredentials);
System.out.println("1");
S3Bucket testBucket = s3Service.getOrCreateBucket("first_test_bucket");
System.out.println("Created test bucket: " + testBucket.getName());
S3Bucket[] myBuckets = s3Service.listAllBuckets();
System.out.println("2");
System.out.println("How many buckets to I have in S3? " + myBuckets.length);
System.out.println("3");
}
catch (Exception e){
System.out.println("exception: " + e.toString());
}
}
}
but I encountered an problem like this

I guess this is a problem about firewall since I’m excuting this code at my company. Does anybody knows this problem? help!
In your – not so easy to read – log there are some “Connection timed out: connect exception: …”. So, yes, it may be because you are behind a proxy (Amazon S3 Rest services listen on port 443).
You may want to configure JetS3t to use a proxy.
Create a jets3t.properties property file and add the following properties:
more info here: http://jets3t.s3.amazonaws.com/toolkit/configuration.html#jets3t
Also, please note that there is a somehow stable S3 test stub that you can use for testing:
