Issue running camunda Script task with java 17, which doesnt support Noshorn

Camunda Script task, if you try to run script with java 17 with camunda, the following errors are throws, It is because of 

The Nashorn JavaScript Engine has been removed from Java. Deprecated in Java 11, removed in Java 15.

So you need to use different script engine, as GraalVM.

Best Java based open source distributed workflow engine for production use

 There are several Java-based open-source workflow engines that are widely used for production purposes. Here are a few options to consider:

Apache Airflow - Airflow is a popular workflow engine that provides a flexible platform to programmatically author, schedule, and monitor workflows. It supports a wide range of data processing tasks and offers a rich set of features, including an intuitive user interface, DAG visualization, and extensibility.

Activiti - Activiti is a lightweight and scalable workflow and BPMN platform that enables users to automate business processes and workflows. It offers a powerful and flexible workflow engine that can be easily integrated with other systems, including Java applications.

Camunda - Camunda is a lightweight, open-source workflow engine that provides a powerful platform for business process automation. It offers a user-friendly interface and a robust set of features, including process modeling, task management, and workflow automation.

Netflix Conductor - Netflix Conductor is an open-source workflow orchestration engine that supports distributed, microservice-based architectures. It offers a set of powerful features, including task scheduling, event-driven workflows, and parallel processing.

Each of these options has its strengths and weaknesses, so it's essential to evaluate each one based on your specific needs and requirements

While running docker-compose with vue.js application, It keeps throwing error as following

1.  web_1     | sh: vue-cli-service: not found
2.  server_1  | > tslint -c tslint.json -p tsconfig.json --fix

It is found that While running the docker-compose the path to the vue-cli-service/tslint is not found.

Solution:

• Install the vue cli as global in Dockerfile as follows.
• Include the path to the bat/exe to the docker environment path as follows.

Sample Dockerfile:

FROM node:12.2.0-alpine

WORKDIR /app

COPY . /app

ENV PATH /app/node_modules/.bin:$PATH

RUN npm install -g typescript

RUN npm install -g tslint

RUN npm install

CMD ["npm", "run","start"]

isPalindrome Implementation in Scala

The palindrome function will check the Given Number/ String is Palindrome or In case of List of Items It will test individual items in list can contribute to a Palindrome or Not.

def isPalindrome[A](item:A):Boolean = item match {
  case head :: Nil => isPalindrome(head)
  case ls:List[A] => ls.head == ls.last &&  isPalindrome(ls.drop(1).dropRight(1))// Checks the Head and Tail, and recursively check for the remaining
  case ls:String => ls.reverse == ls
  case e => e.toString.reverse == e.toString
}

println("IS Palindrome :"+isPalindrome(1234454321))  // Result false
println("IS Palindrome :"+isPalindrome(List(1,2,3,4,3,2,1)))  // Result true
println("IS Palindrome :"+isPalindrome("ABCDCBA"))  // Result true

Shortcut in Visual Code for ReactJs

1. Type rfc and press TAB key, It will create a Rect Functional Component skeleton

Example:

import React from 'react'

export default function Launch() {

return (

<div>

</div>

)

}

If you type rcf: the Auto suggestion will point to rfc ;)
2. Type rcc and press TAB key, It will create a Rect Class Component skeleton

import React, { Component } from 'react'

export default class Launch extends Component {

render() {

return (

<div>

</div>

)

}

}

How to run docker-compose in windows 10 Home - kitematic

As Windows-10 Home doesnt support Hyper-V, While running docker-compose in windows 10 Home, You cannot map the current directory in windows to the docker volume,

I did the following solution:

1. Connect Kitematic VM using WinSCP
1. IP Address : 192.168.99.100
2. UserName: docker
3. Password : tcuser
2. Upload all files for the docker container to the VM
1. Example /home/docker/nginx
3. Map the Volume to the folder in docker-compose.yml [Where the docker-compose.yml is still in the Windows machine, while all the container file is uploaded to the Kitematic VM -192.168.99.100 ]

version: '3'

services:

proxy:

image: nginx:1.13 # this will use the latest version of 1.13.x

ports:

- '80:80' # expose 80 on host and sent to 80 in container

volumes:

- /home/docker/nginx/nginx.conf:/etc/nginx/conf.d/default.conf

1. From windows Command prompt run docker-compose up

The above steps helped to run docker-compose. 

If you have any other thoughts please share in comments.

Map windows directory to docker container in windows Kitematic

By default the directory mapped to docker container inside Kitematic will be mapped to VM of the kitematic, not the windows directory,

So the solution is as follows.

1. Make a directory inside kitematic VM and map it.
2. Map a Windows directory to the VM through VirtualBox manager and map to the docker.

Using localhost for to access running docker container in windows

In Windows, The docker is run through Kitematic which is basically a VM.

The VM will have an IP address associated with it, So to access from windows you need to specify the IP address of teh Kitematic VM IP instead of localhost for the deployed docker file access.

Stack Implementation using Queue - Java Code

Get Implementation below:

     
import java.util.ArrayDeque;
import java.util.Queue;

public class StackUsingQueue {
 Queue q1=new ArrayDeque<>();
 Queue q2=new ArrayDeque<>();
 
 public void push(Integer item) {
  if(!q1.isEmpty())
   q1.add(item);
  else
   q2.add(item);
  System.out.println("PUSH "+item+": Q1: "+q1+"   Q2"+q2);
 }
 public void pop() {
  Integer item ;
  if(!q1.isEmpty()) {
   transfer(q1, q2);
   item = q1.poll();
  }else {
   transfer(q2, q1);
   item = q2.poll();
  }
  System.out.println("POP : Q1: "+q1+"   Q2"+q2+"  -  Poped Item:"+item);
 }
 
 private void transfer(Queue q1, Queue q2) {
  Integer size = q1.size();
  for(int i=0; i< size - 1; i++)
   q2.add(q1.poll());
 }
 public static void main(String[] args) {
  StackUsingQueue stack = new StackUsingQueue();
  stack.push(1);
  stack.push(2);
  stack.pop();
  stack.push(3);
  stack.push(4);
  stack.pop();
  stack.pop();
 }
  }

Result

PUSH 1: Q1: []   Q2[1]
PUSH 2: Q1: []   Q2[1, 2]
POP : Q1: [1]   Q2[]  -  Poped Item:2
PUSH 3: Q1: [1, 3]   Q2[]
PUSH 4: Q1: [1, 3, 4]   Q2[]
POP : Q1: []   Q2[1, 3]  -  Poped Item:4
POP : Q1: [1]   Q2[]  -  Poped Item:3

Why Crontab Scripts are not running ?

Sometimes The bash scripts runs good at the Terminal, But doesnt execute while running from cromtab.

I faced same issue with multiple commands chained in a crontab,

Solution: Issue behind the command is, while executing crontab everu command should have have the complete path.

You can find the command path as follows:
for example xargs

• Execute "which xargs" which will give the complete path as /usr/bin/xargs

So I formated my cronjob as follows:

• Before Path : 44 * * * * echo $(service MyService status | xargs -n 1 lsof -p | wc -l) 
• After Path : 44 * * * * echo $(/sbin/service MyService status | /usr/bin/xargs -n 1 /usr/bin/lsof -p | /usr/bin/wc -l)

Solution:
The error "class file has wrong version 52.0, should be 50.0"
It means your Java runtime version is 1.8, but your compiler version (javac) is 1.6. To simply solve it, just retreat the Java version from 1.8 to 1.6.

Enjoy coding...
