Two things: #1. I suspect you might need to add psql jar support in jasperserver. See http://community.jaspersoft.com/wiki/no-query-executer-factory-registered-plsql-language-jasperserver-51 #2. If you want more granular details about why your report is not publishing, go take a look at the jasperserver logs (catalina.out or jasperserver.log) As the previous commenter noted, JasperStudio 5.6 doesnt really give you helpful info for debugging report issues. hope this helps, casey
