Spring batch 3.0.2 dependency with javax.batch.runtime.JobInstance

Updates:

After adding javax.batch-api-1.0.jar file, the below exception is gone and the application is up an running.

Origianl Post

I have been using Java 6 along with Spring batch and Integration for a year by now. Application is a stand alone java application using Java 1.6.

Since the version of spring batch is so outdated, I am trying to update the libraries today. I upgraded,

• Spring framework from 3.2 to 4.1.2
• Spring batch from 2.1 to 3.0.2
• Spring Integration from 2.2 to 4.1

Due to the upgrade, I added a new jar file which is Spring-retry-1.1.jar

After the upgrade, I am having below exception.

Caused by: java.lang.ClassNotFoundException: javax.batch.runtime.JobInstance at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) 

It looks like spring batch core 3.0.2 does not support Java SE6 for me. It looks like Java EE7 package. However when I dig the spring batch document, it says it support Java 6,7,8.

Does anybody knows what is going on Spring batch core 3.0.2 with Java version?

This is not a java version issue - it looks your missing jars on your run-time class path

How are you managing your dependencies? The spring batch 3.0.2 depends on a jar --> Javax.batch API that contains the class in question.

Note the dependency is not optional. The Spring JobInstance class implements the JobInstance and as such is a required dependency.

Class JobInstance

 All Implemented Interfaces: java.io.Serializable, javax.batch.runtime.JobInstance
