Hi Ching, Rather than having the jasperserver database running on POSTGRES, I would like to have the jasperserver database running on MYSQL. MYSQL was the database server for the jasperserver database in eariler versions of JasperReport server. I have the MYSQL JDBC driver installed and working. I can connect to other MYSQL databases, no problem. However, I will be running MYSQL on the jasper server which will run a copy of various production databases for reporting purposes and I do not want to run 2 databases servers on the jasper report server, simply to make database administration easier. So I would like to get rid of POSTGRES altogether. My question is how to do that and is there any documentation about this? Thanks Oliver ps - your english is pretty good!
