Dynamic Scheduling of Jobs

[yoshah]

How can one schedule jobs using Quartz 1.8.6 Job Scheduler + Spring Batch 2.1 using the scheduling parameters provided, say, in a simple HTML form? I actually want this: "the user enters the scheduling time for job in a form, clicks submit, then the job gets executed at the specified time". I am currently using Cron Expressions. My XML Snippet is as follows:

<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronT riggerBean">
<property name="jobDetail" ref="jobDetail"/>
<property name="cronExpression" value="* 43 18 ? * *"/>
</bean>

Using this approach, the scheduling parameters are hard-coded. I dont want that. Please help!

I got it!,,,
used java Configuration

@Configuration
public class CustomCronExpression{

//,......
@Bean
public String constructCronExpression(HttpServletRequest request) {
String cronExpression = ....; //Contruct Cron Expression from the request
return "cronExpression ";
}
//.....
}

Finally my batch config file will look the following:

<bean id="cronTrigger" class="org.springframework.scheduling.quartz.CronT riggerBean">
<property name="jobDetail" ref="jobDetail"/>
<property name="cronExpression" ref="constructCronExpression"/>
</bean>
