[Report JSON whit subreport]

No body try this???

[Report JSON whit subreport]

I did a clean installation of JRE 7, iReport 4.5.1 in a refresh instalation of Windows XP SP3. I created a new report with JSON Datasource. When I run this report without sub-report, everything is fine, but when I run with a sub-datasource, this exception was throws java.lang.ClassNotFoundException: net.sf.jasperreports.engine.data.JsonDataSource....AND THIS IS STRANGE BECAUSE I RUN IN THE IREPORT DESIGNER.

The subreport expresion is:

new net.sf.jasperreports.engine.data.JsonDataSource(new java.net.URL($P{net.sf.jasperreports.json.source}).openStream(),"response.tickets")

I use java.net.URL() because this json is generate by PHP dynamicly.

This is a bug? or Miss configuration?

 

sorry for my bad english
