How to execute a spring batch job by clicking on a button in a jsp page? - spring-mvc

Question

I'm a newbie in spring batch and spring Mvc, and I want that a batch job (which extracts data from a database and writes it in another database) is executed from a jsp page by clicking on a button (or a link if it's possible) I'm using spring Mvc. This is my job configuration:
<bean id="jobRepository"
class="org.springframework.batch.core.repository.support.JobRepositoryFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="transactionManager" ref="transactionManager" />
<property name="databaseType" value="oracle" />
</bean>
<bean id="itemReader"
class="org.springframework.batch.item.database.JdbcCursorItemReader"
scope="step">
<property name="dataSource" ref="dataSource" />
<property name="sql"
value="select id,name,qual from users" />
<property name="rowMapper">
<bean class="tn.com.spring.UserRowMapper" />
</property>
</bean>
<bean id="oracleitemWriter"
class="org.springframework.batch.item.database.JdbcBatchItemWriter">
<property name="dataSource" ref="dataSource" />
<property name="sql">
<value>
<![CDATA[
insert into users2(id,name,qual)
values (:id,:name,:qual)
]]>
</value>
</property>
<property name="itemSqlParameterSourceProvider">
<bean
class="org.springframework.batch.item.database.BeanPropertyItemSqlParameterSourceProvider" />
</property>
</bean>
<batch:job id="Job" job-repository="jobRepository">
<batch:step id="step1">
<batch:tasklet transaction-manager="transactionManager">
<batch:chunk reader="itemReader" writer="oracleitemWriter"
commit-interval=" 10">
</batch:chunk>
</batch:tasklet>
</batch:step>
</batch:job>
<jdbc:initialize-database data-source="dataSource">
<jdbc:script
location="org/springframework/batch/core/schema-drop-oracle10g.sql" />
<jdbc:script location="org/springframework/batch/core/schema-oracle10g.sql" />
</jdbc:initialize-database>
and this is my job controller (I found it in the net but still not working!)
#Component
#Controller()
public class JobController {
#Autowired
#Qualifier("JobLauncher")
private JobLauncher jobLauncher;
#Autowired
#Qualifier("Job")
private Job job;
#RequestMapping(value = "/job")
public void job() {
try {
JobExecution execution = jobLauncher.run(job, new JobParameters());
} catch (Exception e) {
throw new RuntimeException(e);
}
}
}
and here is the button
<form action=" <%=application.getContextPath()%>/job" method="get">
<input type="submit" value="execute My job" />
</form>
Could you please help me ? Whats's missing in my configuration?
I'm confused !
Thanks in advance.

As a solution for this problem, I have made this javascript code which will invoke the execution of the job :
$(function() {
$('#JobBtn').click(function() {
$.get('${batchJobUrl}');
});
});
and in the jsp page you need to specify the Id of the button writen in the javascript code:
<input type="button" value="execute job " id='JobBtn' class="btn" />
I Hope it will help someOne..
