Remote Debugging of Java Application deployed on AWS Elastic Beanstalk

Most of the time we stuck in the situation where we need to do remote debugging of the application which is running on some server or somewhere other than localhost. We need to debug the code in eclipse. To do that we need to allow the running application to allow remote debugging. 

Generally, we know how to do remote debug in eclipse while the code is running on tomcat. In this post, we will see how to do remote debug when the application is deployed over AWS by elastic beanstalk.

Let's start.

To do Remote debug of AWS deployed the application, we need to follow below steps.

1)We need to Go to AWS Console -> Elastic Beanstalk -> Application -> Configuration

2) Under Configuration you need to go to Software ->Modify ->Container Options 
 Now in Container Options, search for JVM options    In this text box you need to write the below arguments.
-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005
Now, these arguments say that - The remote debug will be listening at 5005 port.

3) Now you need to Go to EC2 Instance running from AWS Console -> EC2

4) After that you need to check which security group is defined for that EC2 Instance, you need to allow this port to communicate outside AWS.

5)For that, you need to add the Port in Inbound and Outbound of the Security Group
   Select the Custom Protocol and define the Port as 5005 and then define Anywhere in Ip accessible.

After this, you will be able to communicate the port with the local debugger of the eclipse.

Now you need to configure the Local Eclipse environment for Remote debugging.

Configure Local Eclipse 

For this you need to go to  Run ->Debug Configuration -> Remote debugging 

Under that define the IP of the application ( you need to find the IP of the application at EC2 Instance Properties )

Define the port as 5005 ( as defined above).

Run the application and hurray, are now connected with the AWS application running.

Now you will be able to debug remotely.
