Call Servlet from Schedular

It is not a best practice nor recommend way to call a servlet from scheduler. You can call a service from scheduler. Move the existing logic in Servlet to a OSGi service or write a new service and call that OSGi service in your scheduler.This promotes better separation of concerns, code reusability, and easier testing.

High Level Steps - Sequence:

1. Create OSGi Service (This service should contain the logic that you currently have in your servlet.)
2. Update your servlet to call the new service instead of containing the logic itself. (optional) - if you want to keep the servlet for any other purposes.
3. Create a scheduler that also calls the new service.

@sateeshre2 This is one only one way to call HTTP call to this servlet and fetch the same. 

There is a best way to resolve you issue, we already have an access to ReportCSVExportServlet.java as part of below link and you can also perform same operation after copying this code under service class. Hitting a servlet will impact AEM publish performance.

Hi @sateeshre2 
Please try this way

1. Create a new job consumer: In your AEM project, create a new job consumer that will execute the servlet. You can create a new Java class that implements the `org.apache.sling.event.jobs.consumer.JobConsumer` interface. In the `process` method of this class, you can use the `SlingHttpServletResponse` object to call the servlet URL and generate the report.

2. Create a new job: In your scheduler, create a new job that will trigger the job consumer. You can use the `org.apache.sling.event.jobs.JobManager` API to create a new job. Set the job topic to a unique value and add any job properties that are required by your job consumer.

3. Schedule the job: Finally, schedule the job to run at the desired frequency. You can use the `org.apache.sling.event.jobs.JobManager` API to schedule the job. Set the scheduling expression to the desired frequency, such as `0 0 1 * * ?` to run the job every day at 1 AM.

In your scheduler, you can create a new job using the following code:

@Reference
private JobManager jobManager;

public void scheduleReportGeneration() {
    // Create a new job with the topic "myproject/generate-report"
    Job job = jobManager.createJob("myproject/generate-report")
            .setProperty("reportType", "monthly")
            .setProperty("startDate", "2022-01-01")
            .setProperty("endDate", "2022-01-31")
            .build();

    // Schedule the job to run every day at 1 AM
    String schedulingExpression = "0 0 1 * * ?";
    jobManager.addJob(job, schedulingExpression);
}
