Hi we have this problem We have a Report which includes 8 subreports. Every subreport executes sql queries to retrieve data from database. After report visualization in browser if we try to modify, using our application, some data stored in tables, we found the tables locked. We use tomcat 5.0.28, oracle lite 10g, hibernate 3.1.3 Jasper report 1.2.1. I've tried jr version 1.2.6 but I have the same problem. Any idea? Thanx Matteo
