I figured scheduling the jobs through the JasperReports Server would be quickest and simplest. I was thinking that scheduling them this way would do everything for me...run asynchronously, get the report output, and email out the results. Using the reportExecutions, I will need to execute the report, poll the report executions, request the execution details, request and download the output, then email it out.

We need to run the same report with different parameters a mass amount of times (approximately 9000) for our store users at year end. Last year, the users manually ran the reports themselves and ended up bringing the system down. This year we were thinking of scheduling all of the reports for them. This has to happen at the end of their work day in a small window of time. We have done load testing against this report to figure out what our max load is. I have used the REST API to schedule all of the jobs, but my problem with that is that it only lets me schedule the report down to the minute level. I cannot set seconds on the start time. I was thinking if I could set the seconds then we could stagger kicking off the reports better. Otherwise, I would have to kick off about 300 every minute. My question is....how would the scheduler handle that? I fear that load would be too heavy. If I can't get them scheduled properly by setting a start time, I was thinking of having a program create the jobs to run immediately and have the program handle the time intervals. Thoughts and suggestions on our dilemma? Thanks!

I was wondering if there are any implications or concerns to be aware of when using one generic user and password embedded in the URL to access a report. Such as, if multiple people are using the same URL to access the report and the report runs under that same generic user, is there any issues with how caching works. Could one person potentially get results from what another person was running? I am unfamiliar with how user caching works.

After running a report through the Jasper repository and the report results display in the browser, if I select the option to export to PDF, does the query for the report get re-executed or is it using the data results from when it initially ran?
