Thanks Eline

Thanks Akshata

Thanks for help,

This library was the best I can get for my requirements (it did complete my 90% of requirements).

Though with static method i was able to get job done but i had to have access details hardcoded in method which i feel is not that possible way.

So i was thinking about the intial suggestion which you gave me of using roles , but i am not sure how it works so if you can give me some reference URL it will be really helpful.

Thanks for the solution.

When I use static method without any parameters it worked but same when i tried to do with paraneters it is not working.

working : com.aws.AWSClient.createClient

not working : com.aws.AWSClient.createClient("us-east-1","access-key","secret-key")

I tried escaping double quotes with " but still it gives me below error.

2020-05-07 18:57:12,348 com-kdgregory-aws-logwriter-log4j2-cloudwatch-1 ERROR failed to create client via configured factory: com.aws.AWSClient.createClient("us-east-1","access-key","secret-key") java.lang.NoSuchMethodException:

I did write a custom appender wherenin I could use the credentails as below

com.amazonaws.services.logs.AWSLogsClientBuilder.standard().withRegion(Regions.fromName(awsRegion)).withCredentials(new AWSStaticCredentialsProvider(new BasicAWSCredentials(this.awsAccessKey, this.awsAccessSecret))).build();

but then i started struggling with dynamic value for logGroup which i am not able to handle in my code and which your code is able to do.

So now i want to have combination of both. so can you help ?

Also I got one issue while trying to use your library not sure why.

Property files are well encrypted and kept so the security is not any issue.

So if still i want to use the property then there is no way to do it with this library?

Where AWS access key and secret keys goes?.I dont see any property where I can assgin that
