I am lost with GPL issues. I use Jasper Reports in my commercial application. I added a datasource for my needs. But now I would like to allow my customers to build their reports using IReport and upload them to my server. To meet my needs, my customers need to use my datasource , so I would like to add a plugin to IReport with the following files : plugin xml file + DataSourceConnnection class file + DatasourceConnectionEditor class file + DatasourcePlugin class file + Of course my Datasource class file. This is where my problem arise. What have to be released under GPL ? I am nearly sure that the following files have to be released under GPL: the IReport plugins files (plugin xml file + DataSourceConnection class file + DatasourceConnectionEditor class file + DatasourcePlugin class file) because they are specific to IReport. But what about my Datasource class file. I am not sure that it have to be released under GPL since this is a JasperReports add on and not a IReport add on. I the Datasource have to be released under GPL, then my whole commercial application has to be released under GPL because my application uses the datasource. I don't want my application to be under GPL. Can someone tell me what is allowed in my case with GPL ?

Do JasperReport plan to provide a new kind of datasource based on JXPATH working as the JRXMLdatasource. This datasource could allow access to data from both XML and Java Object without modification in reports design. This kind of datasource is convenient in the case where you want to design your reports (with JasperAssistant or IReport for example) disconnected from your server, when firewall does not allow JDBC. You download XML, build your report using JRXMLdatasource and finally upload the report to your server. On the server side your use JXPATH Datasource on java objects for speed reasons. Thank you for your answer.
