Hi,
I have defined a Spring Batch job which runs once just fine. However it is unable to run a second time due to a duplicate entry in the primary key for the JOB_INSTANCE_ID;
I've read that this can be over-come by setting command line parameters on the job, e.g.Code:SEVERE: Job Terminated in error: PreparedStatementCallback; SQL [INSERT into BATCH_JOB_INSTANCE(JOB_INSTANCE_ID, JOB_NAME, JOB_KEY, VERSION) values (?, ?, ?, ?)]; Duplicate entry '0' for key 'PRIMARY'; nested exception is com.mysql.jdbc.exceptions.jdbc4.MySQLIntegrityConstraintViolationException: Duplicate entry '0' for key 'PRIMARY'
Whether I include the -next parameter or not, it will not run the job.Code:java -cp ${CLASSPATH} org.springframework.batch.core.launch.support.CommandLineJobRunner myJob.xml myJob date=20121025154016 -next
My Spring Batch configuration looks as follows (batch/launchContext.xml);
And the job is like this (in the myJob.xml file)Code:<?xml version="1.0" encoding="UTF-8"?>

</bean>
<bean
id="jobExplorer"
class="org.springframework.batch.core.explore.support.JobExplorerFactoryBean">
<property

ref="dataSource" />
</bean>
</beans>
Ideally what I'd like is each run of the job to be persisted with the run date/time. Is there a way to configure the launcher to do this automatically?Code:....
<import resource="batch/launchContext.xml" />
...
<batch:job
id="myJob"
job-repository="jobRepository"
incrementer="incrementer">
<batch:step id="step1">
<batch:tasklet transaction-manager="transactionManager">
<batch:chunk
reader="myReader"
processor="myProcessor"
writer="myWriter"
commit-interval="10" />
</batch:tasklet>
</batch:step>
</batch:job>
Thanks,
John
