When I try to run this code to execute a batchjob:
JobOperator jo = BatchRuntime.getJobOperator();
Properties props = new Properties();
long jobId = jo.start("tweetimport", props);
I keep getting an error. When I tried to run it from the servlet I got this error:
Severe: Could not instantiate service: com.ibm.jbatch.container.impl.BatchKernelImpl due to exception:java.lang.reflect.InvocationTargetException
Warning: StandardWrapperValve[KwetterServlet]: Servlet.service() for servlet KwetterServlet threw exception
java.util.ServiceConfigurationError: javax.batch.operations.JobOperator: Provider com.ibm.jbatch.container.api.impl.JobOperatorImpl could not be instantiated
When I run it from a normal java class I get this errror:
mrt 21, 2016 10:19:08 AM javax.batch.runtime.BatchRuntime getJobOperator
WARNING: The ServiceLoader was unable to find an implementation for JobOperator. Check classpath for META-INF/services/javax.batch.operations.JobOperator file.

I have this tweetimport.xml file in Other Sources > src/main/resources > META-INF.batch-jobs

I can't figure out why I'm getting this error. The link to my project
