Hi All, it seems that this question has been asked numerous times but so far I haven't quite had success in applying the answers given to my current environment: Windows Server 2008 R2 64Bit JasperReports Server 4.7.0 Community Edition Oracle 11g R2 DBThe server is running quite nicely but it's using the preinstalled PostgreSQL db and I would like to switch to Oracle. Yes, I know this is not supported for the CE but still I would at least like to try it out and see for myself. In addition, my customer is Oracle-only and introducing PostgreSQL to his infrastructure would not really be welcome. Having said that, the advice I can find here says to build the DDL script from source but the descriptions given on how to do that seem to be outdated at best. I have downloaded jasperreports-server-4.7.0-src.zip and created/adjusted buildomaticconf-sourcedboracledb.properties, added the required .jar file (ojdbc6) and made some other configuration changes (default_master.properties etc.) BUT ant refuses to generate anything. In fact, the only thing I'm after is a usable script for creating the required db objects on an Oracle db but even that is not created. Any ideas? Where is a _usable_ description of what needs to be done in order to achieve this? TIA jaspernooby
