spring batch NoSuchBeanDefinitionException

I have developed a spring batch for loading users into a DB. I am able to run it as a Java Application from eclipse providing the main class but not able to run the batch by a shell script on a unix server. I get this exception:

    org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'jobLauncher' is defined

I have my beans declared in a job.xml file as follows
