ElasticBeanstalk Client

Question

I try to develop an elastic beanstalk client interface to connect through it to my amazon account elasticbeanstalk. I used my account's credentials from the script file credentials.Csl. I signed up to my account from Google chrome but I'm getting errors. Here is my code.

package PFE;


import com.amazonaws.AmazonClientException;
import com.amazonaws.AmazonServiceException;
import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.profile.ProfileCredentialsProvider;
import com.amazonaws.regions.Region;
import com.amazonaws.regions.Regions;
import com.amazonaws.services.elasticbeanstalk.AWSElasticBeanstalk;
import com.amazonaws.services.elasticbeanstalk.AWSElasticBeanstalkClient;
import com.amazonaws.services.elasticbeanstalk.model.CheckDNSAvailabilityResult;

public class Sample {

    static AWSElasticBeanstalk      eb;

    private static void init()throws Exception{


 /*
  * The ProfileCredentialsProvider will return your [default]
  * credential profile by reading from the credentials file located at
  * (~/.aws/credentials).
  */
    AWSCredentials credentials = null;

    try {

        credentials = new ProfileCredentialsProvider().getCredentials();

    } catch (Exception e) {
        throw new AmazonClientException(
             "Cannot load the credentials from the credential profiles file. " +
             "Please make sure that your credentials file is at the correct " +
             "location (~/.aws/credentials), and is in valid format.",
             e);
    }

    eb = new AWSElasticBeanstalkClient(credentials);
    Region usWest2 = Region.getRegion(Regions.US_WEST_2);
    eb.setRegion(usWest2);
}

public static void main(String[] args) throws Exception {

    init();    
    try {            
        CheckDNSAvailabilityResult c= eb.checkDNSAvailability(null);

        System.out.println("You have access to " + c.getAvailable() +
                           " Availability Zones.")

        eb.createStorageLocation();

    } catch (AmazonServiceException ase) {
        System.out.println("Caught Exception: " + ase.getMessage());
        System.out.println("Reponse Status Code: " + ase.getStatusCode());
        System.out.println("Error Code: " + ase.getErrorCode());
       System.out.println("Request ID: " + ase.getRequestId());
    }                  
}

}

Here are the errors that I got when running my project

 Exception in thread "main" java.lang.NoClassDefFoundError:org/apache/commons/logging/LogFactory at com.amazonaws.auth.profile.ProfilesConfigFile.<clinit>(ProfilesConfigFile.java:62) at com.amazonaws.auth.profile.ProfileCredentialsProvider.getCredentials(ProfileCredentialsProvider.java:106)

I thought the problem is with the org.apache.commons.logging.LogFactory library so I downloaded it and added it to my referenced libraries but I'm still getting the same errors.

Answer 1

I got the same error while trying to make a SQS sample... My solution is: Don't add AWS SDK for Java as as an external jar

But as a library.

Answer 2

Instructions for NetBeans IDE:

1. Download "SDK for Java" from this page

2. Extract all files from archive for example in folder /aws-java-sdk-1.9.22

3. Copy next files to your project:

   • /aws-java-sdk-1.9.22/lib/aws-java-sdk-1.9.22.jar

   • All *.jar files from folder: /aws-java-sdk-1.9.22/third-party/

4. Now, just add all *.jar files to your project in NetBeans IDE.

5. Profit!
