Adding a group policy – Inline

Add inline policy under the group. If the same policy name is available under the group, it will update it:

String inlineGroupPolicyName = "S3FullAccessOnMyBucket2";

  
String inlineGroupPolicyDocument =  
   readFromFile("NewPolicyDocument.json");

  
putGroupPolicy(groupName, inlineGroupPolicyName,  
      inlineGroupPolicyDocument); 
........ 
 
public void putGroupPolicy(
         String groupName,
         String policyName,
         String policyDocument) {
     PutGroupPolicyRequest putGroupPolicyRequest =
             new PutGroupPolicyRequest()
                     .withGroupName(groupName)
                     .withPolicyName(policyName)
                     .withPolicyDocument(policyDocument);

     PutGroupPolicyResult putGroupPolicyResult =
             amazonIdentityManagement.
                     putGroupPolicy(putGroupPolicyRequest);
 }
