Introduction

JS7 offers a number of JS7 - Job Classes including JS7 - Shell Jobs, JS7 - JavaScript Jobs and Java Jobs.

  • Java Jobs are operated in the Java Virtual Machine of the JS7 Agent
  • Java Jobs are loaded on start-up of the JS7 Agent, this means there is zero latency when starting Java Jobs.

JS7 offers the JS7 - Job API to Java Jobs that serves the purpose of

  • accessing arguments available to the job from various sources such as JS7 - Order Variables, job and node arguments, JS7 - Job Resources,
  • allowing to specify the outcome of a job including return values that are passed to subsequent jobs from order variables.

Java jobs are available starting from the following releases:

FEATURE AVAILABILITY STARTING FROM RELEASE 2.5.4

FEATURE AVAILABILITY STARTING FROM RELEASE 2.6.1

Implementation

Implementing a basic Job

A Java Job extends the class com.sos.js7.job.Job like this:

Example for implementation of a HelloWorld job with Java
import com.sos.js7.job.Job;
import com.sos.js7.job.JobArguments;
import com.sos.js7.job.OrderProcessStep;

public class HelloWorld extends Job<JobArguments> {

	@Override
	public void processOrder(OrderProcessStep<JobArguments> step) throws Exception {
		
		step.getLogger().info("Hello World!");
		
	}

}


Explanation:

  • The extension of the class com.sos.js7.job.Job is required.
  • The processOrder() method is required to be implemented by the job.
    • The method is parameterized by the OrderProcessStep object provided by the Job API.

    • The OrderProcessStep object is used with its getLogger() method to write output to the job's log.

Accessing Arguments

A Java Job can access arguments from a number of sources, see JS7 - Job API. 

  • The straightforward way how to read arguments is explained from the next chapter.

Example: Reading specific Arguments

Example for implementation of a Job with Java
import java.util.List;

import com.sos.js7.job.Job;
import com.sos.js7.job.JobArgument;
import com.sos.js7.job.OrderProcessStep;
import com.sos.js7.job.OrderProcessStepOutcome;

public class JobWithParams extends Job<MyJobArguments> {

	@Override
	public void processOrder(OrderProcessStep<MyJobArguments> step) throws Exception {
		
		// reading all arguments with "getAllArgumentsAsNameValueMap"
		step.getAllArgumentsAsNameValueMap().forEach((name, value) -> {
			step.getLogger().info("argument: " + name + "=" + value);
		});
		
		// reading all arguments with "getAllArguments"
		step.getAllArguments().forEach((name, jobArgument) -> {
			step.getLogger().info("argument: " + name + "=" + jobArgument.getValue());
		});
        
        MyJobArguments myArgs = step.getDeclaredArguments();
		
		// reading job-specific argument: myString
		JobArgument<String> myString = myArgs.getMyString();
		step.getLogger().info(myString.getName() + "=" + myString.getValue());
		
		// reading job-specific argument: myBool
		JobArgument<Boolean> myBool = myArgs.getMyBool();
		step.getLogger().info(myBool.getName() + "=" + myBool.getValue());
		
		// reading job-specific argument: myList
		JobArgument<List<String>> myList = myArgs.getMyList();
		step.getLogger().info(myList.getName() + "=" + myList.getValue());
		
		// return values
		OrderProcessStepOutcome outcome = step.getOutcome();
		outcome.putVariable(myString.getName(), "hello world");
		outcome.putVariable("myInteger", 42);
	}

}


Explanation:

  • The getAllArgumentsAsNameValueMap() method provides a map of all argument values.
  • The getAllArguments() method provides a map of argument objects.
  • The OrderProcessStep object is here typed by MyJobArguments that is a class with job-specific declared arguments.

    • A class with job specific declared arguments extends com.sos.js7.job.JobArguments

      Example of a class of the job-specific declared arguments
      import java.util.List;

import com.sos.js7.job.JobArgument;
import com.sos.js7.job.JobArguments;

public class MyJobArguments extends JobArguments {
	
	private JobArgument<String> myString = new JobArgument<String>("myString", false);
    private JobArgument<List<String>> myList = new JobArgument<>("myList", false);
    private JobArgument<Boolean> myBool = new JobArgument<>("test", false, true);

    public JobArgument<String> getMyString() {
        return myString;
    }

    public JobArgument<List<String>> getMyList() {
        return myList;
    }

    public JobArgument<Boolean> getMyBool() {
        return myBool;
    }
}
  • For further methods to access arguments see JS7 - Job API. 

Creating a Maven project in the development environment

The classes com.sos.js7.job.Job, com.sos.js7.job.JobArguments etc. are not available in a public Maven repository, so a local repository must be created in the Maven project.

  • The directory sos has to be created



  • The following .jar files have to be copied from a JS7 Agent installation's ./lib/sos directory to the sos directory of the Maven project. The example makes use of release 2.6.1, users should check for a current release.
    • com.sos-berlin.js7.engine.js7-base-<version>.jar
    • com.sos-berlin.js7.engine.js7-data-for-java-<version>.jar
    • com.sos-berlin.js7.engine.js7-launcher-for-java-<version>.jar
      • Note: Since release 2.6.4, the three jar files mentioned above have been combined into one jar file
      • com.sos-berlin.js7.engine.js7-engine-2.6.4
    • sos-commons-exception-<version>.jar
    • sos-commons-util-<version>.jar
    • sos-js7-job-<version>.jar
  • The following pom.xml file can be used as a base in the Maven project for release < 2.6.4.

  • groupId, artifactId and version should be adjusted.

  • The pom.xml file contains a profile create-local-repo that must be executed once after copying the jar files. It updates the users local .m2 repository with the jars from the sos folder. The dependencies to the .jar files are in scope provided as these jars are needed at compile time, but are already present in the agent environment.

    > mvn initialize -Pcreate-local-repo -U

Activating JUnit Tests and Debugging for JS7 Java Jobs

  • The following .jar files have to be copied additionally from a JS7 Agent installation ./lib/sos directory to the sos directory of the Maven project. The additional .jar files are required in scope test for use with full debugging. The example makes use of release 2.6.1, users should check for a current release.
    • com.sos-berlin.js7.engine.js7-data-<version>.jar
    • sos-js7-job-<version>.jar
    • sos-commons-hibernate-<version>.jar
    • sos-commons-sign-<version>.jar
    • sos-commons-vfs-<version>.jar

Rerun the profile create-local-repo to copy the .jar files to the local Maven .m2 repository. 


> mvn initialize -Pcreate-local-repo -U


The following pom.xml file can be used as a base in the Maven project for JUnit tests and debugging thereof.

Creating a JUnit Test for a JS7 Java job

Thie is an example for a JUnit test class for the JS7 Java job MyJavaJob. 

JUnit Test for JS7 Java Jobs 
package com.sos_berlin.js7jobs;

import java.util.HashMap;
import java.util.Map;

import org.junit.Test;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import com.sos.js7.job.UnitTestJobHelper;
import com.sos.js7jobs.MyJobArguments;
import com.sos.js7jobs.MyJavaJob;

import js7.data_for_java.order.JOutcome;

public class MyJavaJobTest { 
      private static final Logger LOGGER = LoggerFactory.getLogger(MyJavaJobTest.class);

 	    @Test
	    public void test() throws Exception {
	        Map<String, Object> args = new HashMap<>();
	        args.put("myString", "value 1");
	        args.put("test", true);

	        UnitTestJobHelper<MyJobArguments> h = new UnitTestJobHelper<>(new MyJavaJob());
 	        JOutcome.Completed result = h.processOrder(args);
 	        LOGGER.info(String.format("[RESULT]%s", result));
	    }

}

Logging in JUnit Tests

  • Create the folder src/test/resources
  • Add a log4j.xml configuration file to the folder 


Example for a log4j.xml configuration file 
<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
	<Appenders>
		<!-- Appender for root logger -->
		<Console name="stdout" target="SYSTEM_OUT">
			<PatternLayout pattern="%d{ISO8601}{Europe/Berlin} %-5p %-16.16t %-44.70c{1.} - %m%n"/>
		</Console>
	</Appenders>

	<Loggers>
		<!-- General Loggers - set the following loggers to 'debug' to debug the JOC Cockpit -->
    <Logger name="js7.base.io.https.Https" level="warn"/>
		<Logger name="com.sos" level="debug"/>
		<Logger name="org.hibernate.SQL" level="error"/>

		<!-- root logger with console appender. All other loggers inherit from this logger. -->
		<Root level="info">
			<AppenderRef ref="stdout"/>
		</Root>
	</Loggers>
</Configuration>

Adding other sos-berlin .jar files to the repository

There are two ways to install files with the maven-install-plugin to the local .m2 maven repository that are not available in public maven repositories. Please use one of these methods. 

  • Using the pom.xml file
    • this is the recommended way, if the build configuration of the JS7 Java Job has to be portable and should be executed on different environments, for example in shared development.
  • Using  command line
    • For example for testing purposes on a local machine.
    • This should only be used, if a single developer wants to add a dependency quickly in his own local environment. As this is executed locally this is not portable and other developers have to do the same again.

Using the pom.xml file

Add an execution element to the pom.xml file for each .jar file that has to be added. Adjust the values for file, version and artifactId:

<execution>
	    <id>install-${sos.js7.commons.exception.artifactId}</id>
	    <goals>
	         <goal>install-file</goal>
	    </goals>
	    <phase>initialize</phase>
	    <configuration>
	        <file>[filePath]</file>
	        <groupId>${sos.js7.groupId}</groupId>
			<artifactId>[artefactId]</artifactId>
