Create web socker API in 2.6 - problem with code example

Description:

On following documentation
https://docs.wso2.com/display/AM260/Create+a+WebSocket+API
there is a problem with Netty-based WebSocket client that is downloadable in step 11.

In code, in following WebSocketClient.java file on line 93 Keystore location is hardcoded.
String carbonKeyStoreLocation = "/home/isuru/wso2/support/NMDPSUB-9/wso2am-2.1.0/repository/resources"
+ "/security/wso2carbon.jks";

Documentation not covering that you need to change the path which leads to error when you trying to build it and run it

Exception in thread "main" java.io.FileNotFoundException: /home/isuru/wso2/support/NMDPSUB-9/wso2am-2.1.0/repository/resources/security/wso2carbon.jks (No such file or directory)
at java.io.FileInputStream.open0(Native Method)

Steps to reproduce:

Content Positioning in Documentation:

https://docs.wso2.com/display/AM260/Create+a+WebSocket+API

We need to change documentation or change the code to refer to the key store location differently.

NOTE:

I test the same topic for version 3.0 mention on https://apim.docs.wso2.com/en/latest/Learn/Tutorials/create-and-publish-websocket-api/
in step 4
npm install -g wscat

Installation and Invoke have worked without any errors.
