Hello, I was wondering about performance and memory issues with hibernate connection compared to jdbc when used in jasperreports. Hibernate is well known to perform poorly when fetching large amounts of data (100,000 records for example), mainly because of storing all objects in session cache. I don't know much on how exactly jasper uses hibernate, but I would expect those memory problems would be present here as well. What are your experiences when working with reports that require large amounts of data? Does jdbc connection and sql queries performs better? Regards, Igor.
