AWS Lambda Hello World Example with Java | AWS Lambda Tutorials | AWS Serverless Tutorials

AWS Lambda with Java runtime. In this video, I have explained from scratch how can we create a Lambda function from scratch using Java language. On Lambda console, we don't have an option to edit Java code, hence it becomes tricky to use Java with AWS Lambda.
Chapters:
00:00 Introduction and pre-requisites
02:36 Creating Java Project
05:12 Creating Lambda function with Java
06:53 Test Lambda from Console
07:24 Test Lambda from CLI/Cloudshell
09:56 Create Lambda that accepts String Input
11:05 Invoking Lambda from Cloudshell
15:04 DryRun invocation type
If you are not familiar with Lambda theory, you can check my previous video here in which I have covered the theory part in detail.

I can observe that you created video from a learner point of view, and this is too good, like not including any extra dependency, and zooming the video feeling like it might be too small, not using aws-cli in thought that many of might not installed aws-cli and hence used aws-console... liked that part. Doing things in very simple way makes easy to learn and that makes strong base. Good Keep it up.

Do I have to create aws account

[@labeeqjaffar6236]

Very nice Thank you, the example I was looking for. It would be nice if you could have a Rest get/post request calling the lamda from the AWS API Gateway

[@AjayWadhara]

Thanks buddy, i am working on Serverless Api tutorial, stay tuned🚀

[@AjayWadhara]

@@sanjaykatheth3128 Check if your Lambda has the necessary permissions.

[@sanjaykatheth3128]

@@AjayWadhara thank you sir for your response ..i tried it from all the resources which i have still i am facing same kind of issue..
I've tried changing my region, creating the function with default role(basic lambda permissions), new role, existing role and with the options "Author from Scratch", "Use a blueprint", "Serverless app repository" but still getting the same error.
what kind of permission needed to create lamda function??and how to apply these permssion?

[@Akash7Chaudhary]

Do you have any video without maven and using the zip file upload?
also can you tell me what files and folders should I put in the zip file?

[@AjayWadhara]

Sorry, I don’t have that. Somehow I can’t imagine a Java project without a package manager.

[@jatinsharma3792]

That is why Linux command is imp before jump to AWS.
