Getting Started With Spring batch 2.0

Hello world example using spring batch 2.0

Hello world example with spring batch 2.0 along with eclipse.
Follow below steps to start the hello world example with spring batch.

Step 1 : open eclipse - create new java project.
Step 2 : create new xml file under project (applicationContext.xml)
Step 3: create one more xml. under project location.(simpleJob.xml)
Step 4: create one java class which implements
org.springframework.batch.core.step.tasklet.Tasklet
Step 5: override the required methods in your respective class.
Step 6: we can run the job through
org.springframework.batch.core.launch.support.CommandLineJobRunner
This class will take two parameters (Job path and job parameters).
We need to pass those details.
Step 7: Here i am posting, how to run through eclipse.
Right click on the java class( Which we written)- Select RunConfigurations -
Select Main tab- Select Main class as
org.springframework.batch.core.launch.support.CommandLineJobRunner
Click on Arguments - Enter Jobpath and JobParameters under Program arguments
Eg: simpleJob.xml helloWorldJob
Click on the Run Button then hello world will display on the console.

Step 8: Required jar files
commons-logging-1.1.1.jar
javaee-api-5.0-1.jar
log4j-1.2.14.jar
spring-2.5.6.jar
spring-batch-core-2.1.8.RELEASE.jar
spring-batch-infrastructure-2.1.8.RELEASE.jar
spring-beans-2.5.6.jar
spring-context-2.5.6.jar
spring-core-2.5.6.jar
spring-tx-2.5.6.jar
xstream-1.3.1.jar

In this way you can start the Spring batch.
