Can not instantiate class org.eclipse.birt.chart.reportitem.ChartReportItemG eneratio

[Jack]

I'm trying to generate a html file from design .rptdesign
When I try to execute RunAndRenderTask, this exception appears:

Code:

.ChartReportItemG enerationImpl with property class.

I had the same problem:
You've erased the package "org.eclipse.birt.chart.reportitem_2.1.2.v2007 0205-1728" from the Java Build Path
check it
