When email returns an error, pass the error to the error email code and include it in the body of the email

I'm developing a spring boot application to generate an email with a pdf. I need to display the error message exception returned by the document creation service. the document service (and email service ) return a message if there is an exception captured by the Exception handler, and When it returns an error, pass the error to the error email code and include it in the body of the email. and finally I want to test it.
Controller class
Model.addAttribute("permit", permit);
model.addAttribute("success", "Success! Permit for " + permit.getReceipt() + " sent. ");
Map<String, String> result = documentServiceImpl.generatePdf(permit);
if (documentServiceImpl.STATUS_SUCCESS.equals(result.get("status"))) {
model.addAttribute("date", result.get("date"));
String emailBody = getEmailBody(permit);
Map<String, String> emailResult = emailServiceImpl.sendRequestoremail(permit.getEmail(), emailBody, result.get("file"));
documentServiceImpl.deletePdf(result.get("file"));
if (emailServiceImpl.STATUS_ERROR.equals(emailResult.get("status"))) {
String errorE = emailResult.get("message");
String errorEmail = getErrorEmail(errorE);
Map<String,String> financeEmail = emailServiceImpl.sendFinanceEmail(permit.getEmail(), errorEmail);
model.addAttribute("errorEmail", "Received response for the Temporary Parking Permit script but there was an error " + financeEmail);
}
}
// String body = getEmailBody(permit);
System.out.println(result.get("status"));
System.out.println(result.get("file"));
} catch (Exception e) {
model.addAttribute("error", e.getMessage());
}
return "permit";
}
private String getEmailBody( Permit permit) {
ClassLoaderTemplateResolver templateResolver = new ClassLoaderTemplateResolver();
templateResolver.setSuffix(".html");
templateResolver.setTemplateMode(TemplateMode.HTML);
templateResolver.setPrefix("templates/");
TemplateEngine templateEngine = new TemplateEngine();
templateEngine.setTemplateResolver(templateResolver);
Context context = new Context();
context.setVariable("permit", permit);
return templateEngine.process("email" , context);
}
private String getErrorEmail(String permit) {
ClassLoaderTemplateResolver templateResolver = new ClassLoaderTemplateResolver();
templateResolver.setSuffix(".html");
templateResolver.setTemplateMode(TemplateMode.HTML);
templateResolver.setPrefix("templates/");
TemplateEngine templateEngine = new TemplateEngine();
templateEngine.setTemplateResolver(templateResolver);

How to setup user policy for the minio bucket using s3Client?

We use Minio as our backend service but we communicate with it through
software.amazon.awssdk.services.s3.S3Client
I see that this class contains method putBucketPolicy
but I don't see any method which allow to assign policy to user. Is there any way to assigh user policy using S3Client ?

Edited Answer:
Your updated question helped me determine what you were looking for.
You need to create a policy and assign it to a role. You can then assign that role to your user. The AWS SDK for Java 2.x provides support for all of these actions with IAM.
Here's what we can do:
1- Creating a policy
To create a new policy, provide the policy’s name and a JSON-formatted policy document in a CreatePolicyRequest to the IamClient’s createPolicy method.
Imports
import software.amazon.awssdk.core.waiters.WaiterResponse;
import software.amazon.awssdk.services.iam.model.CreatePolicyRequest;
import software.amazon.awssdk.services.iam.model.CreatePolicyResponse;
import software.amazon.awssdk.services.iam.model.GetPolicyRequest;
import software.amazon.awssdk.services.iam.model.GetPolicyResponse;
import software.amazon.awssdk.services.iam.model.IamException;
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.iam.IamClient;
import software.amazon.awssdk.services.iam.waiters.IamWaiter;
Code
public static String createIAMPolicy(IamClient iam, String policyName ) {
try {
// Create an IamWaiter object
IamWaiter iamWaiter = iam.waiter();
CreatePolicyRequest request = CreatePolicyRequest.builder()
.policyName(policyName)
.policyDocument(PolicyDocument).build();
CreatePolicyResponse response = iam.createPolicy(request);
// Wait until the policy is created
GetPolicyRequest polRequest = GetPolicyRequest.builder()
.policyArn(response.policy().arn())
.build();
WaiterResponse<GetPolicyResponse> waitUntilPolicyExists = iamWaiter.waitUntilPolicyExists(polRequest);
waitUntilPolicyExists.matched().response().ifPresent(System.out::println);
return response.policy().arn();
} catch (IamException e) {
System.err.println(e.awsErrorDetails().errorMessage());
System.exit(1);
}
return "" ;
}
You can check out CreatePolicy.java for complete example.
2- Attach a role policy
You can attach a policy to an IAM role by calling the IamClient’s attachRolePolicy method.
Imports
import software.amazon.awssdk.regions.Region;
import software.amazon.awssdk.services.iam.IamClient;
import software.amazon.awssdk.services.iam.model.IamException;
import software.amazon.awssdk.services.iam.model.AttachRolePolicyRequest;
import software.amazon.awssdk.services.iam.model.AttachedPolicy;
import software.amazon.awssdk.services.iam.model.ListAttachedRolePoliciesRequest;
import software.amazon.awssdk.services.iam.model.ListAttachedRolePoliciesResponse;
import java.util.List;
Code
public static void attachIAMRolePolicy(IamClient iam, String roleName, String policyArn ) {
try {
ListAttachedRolePoliciesRequest request = ListAttachedRolePoliciesRequest.builder()
.roleName(roleName)
.build();
ListAttachedRolePoliciesResponse response = iam.listAttachedRolePolicies(request);
List<AttachedPolicy> attachedPolicies = response.attachedPolicies();
// Ensure that the policy is not attached to this role
String polArn = "";
for (AttachedPolicy policy: attachedPolicies) {
polArn = policy.policyArn();
if (polArn.compareTo(policyArn)==0) {
System.out.println(roleName +
" policy is already attached to this role.");
return;
}
}
AttachRolePolicyRequest attachRequest =
AttachRolePolicyRequest.builder()
.roleName(roleName)
.policyArn(policyArn)
.build();
iam.attachRolePolicy(attachRequest);
System.out.println("Successfully attached policy " + policyArn +
" to role " + roleName);
} catch (IamException e) {
System.err.println(e.awsErrorDetails().errorMessage());
System.exit(1);
}
System.out.println("Done");
}
You can check out AttachRolePolicy.java for complete example.

Scenario for create a user and assume a role
The following code example shows how to:
Create a user who has no permissions.
Create a role that grants permission to list Amazon S3 buckets for the account.
Add a policy to let the user assume the role.
Assume the role and list Amazon S3 buckets using temporary credentials.
Delete the policy, role, and user.
/*
To run this Java V2 code example, set up your development environment, including your credentials.
For information, see this documentation topic:
https://docs.aws.amazon.com/sdk-for-java/latest/developer-guide/get-started.html
This example performs these operations:
1. Creates a user that has no permissions.
2. Creates a role and policy that grants Amazon S3 permissions.
3. Creates a role.
4. Grants the user permissions.
5. Gets temporary credentials by assuming the role. Creates an Amazon S3 Service client object with the temporary credentials.
6. Deletes the resources.

Original Answer:
PutBucketPolicy
If you don't have PutBucketPolicy permissions, Amazon S3 returns a 403 Access Denied error. If you have the correct permissions, but you're not using an identity that belongs to the bucket owner's account, Amazon S3 returns a 405 Method Not Allowed error.
You can check out for more from AWS API Reference: PutBucketPolicy

Now can you please suggest how i can generate subfoler.

Java FTP using Apache commons throws "IOException caught while copying"

I have made a JavaFX application which includes uploading large files (> 1GB) to a server. Every time I got the same error on same place. Any Suggestions what am I doing wrong here.
ftpclient.connect(server, port);
ftpclient.login(ftpuser, ftppass);
ftpclient.enterLocalPassiveMode();
ftpclient.setKeepAlive(true);
ftpclient.setControlKeepAliveTimeout(3000);

};
new Thread(copyMnt).start();
Now on the FTPHandler Class
// The constructor will set the ftpclient, source and destinations.
#Override
public void run() {
try {
uploadDirectory(this.getClient(), this.getDest(), this.getSrc(), "");
} catch (IOException ex) {
Logger.getLogger(FTPHandler.class.getName()).log(Level.SEVERE, null, ex);
}
}
public static void uploadDirectory(FTPClient ftpClient,
String remoteDirPath, String localParentDir, String remoteParentDir)
throws IOException {
File localDir = new File(localParentDir);
File[] subFiles = localDir.listFiles();
if (subFiles != null && subFiles.length > 0) {
for (File item : subFiles) {
String remoteFilePath = remoteDirPath + "/" + remoteParentDir

}
} else {

boolean created = ftpClient.makeDirectory(remoteFilePath);
if (created) {
System.out.println("CREATED the directory: "

}
// upload the sub directory
String parent = remoteParentDir + "/" + item.getName();
if (remoteParentDir.equals("")) {
parent = item.getName();
}
localParentDir = item.getAbsolutePath();
uploadDirectory(ftpClient, remoteDirPath, localParentDir,
parent);
}
}
}
}
Every time I am uploading the files (files are of different types like .iso, .dat etc), The first few files (upload sequence is like first few hundred files are smaller i.e less than few MBs then Last 10 files are more than 1 GB big)will be successfully uploaded (i.e all smaller files and 2 of the last 10 files) but when it starts uploading the third big file I get following exception.
SEVERE: null

The CopyStreamException has a "cause" exception. Check that using the .getCause(), to see what went wrong.
See the Util.copyStream method:

long total = 0;
byte[] buffer = new byte[bufferSize >= 0 ? bufferSize : DEFAULT_COPY_BUFFER_SIZE];
try
{

{
....
}
}
catch (IOException e)
{
throw new CopyStreamException("IOException caught while copying.",
total, e);
}
return total;
}
Somewhere in your uploadSingleFile function, do
try
{
ftpClient.storeFile(...)
}
catch (Exception e)
{
e.printStackTrace();
if (e.getCause() != null)
{
e.getCause().printStackTrace();
}
}
I do not know Java, so the code may not be 100% correct.
