问题 I am working on an existing async jasper report in an application wherein the Java backend sends a parameter "employee_id" to the jasper server. Corresponding .jrxml file containing this parameter name "employee_id" executes the SQL query to fetch the results. Now, as per the new functionality, there is a scenario when the application can send more than 1000 employee ids. So, in the Java side, I am creating sublists each containing at the max 1000 elements. e.g. first sublist has param name
