thank you for trying to help me. I use this parameter: $P{REPORT_CONNECTION} This is the default, when I insert the subreport with iReport. With XML_DATA_Document as Subreport datasource expression it doesnt works, too. Maybe you can show me a very small example, that works, it will say more than 1000 words, I hope you can spend a few minute, I am very hopelessly. :silly:
