Hi,

I am using ReportEngine in a standalone application. My application is packed with onejar and with birt 2.6 all working fine. When I was trying to generate report using 3.7.0 I got the following error:
WARING: Failed to install plugin from onejar:lib/
java.lang.ClassCastException: sun.misc.Launcher$AppClassLoader cannot be cast to com.simontuffs.onejar.JarClassLoader

This error happened at Platform.startup( config ) method.

I already removed config.setEngineHome().

Please anyone can help me?

In 3.7 all you should have to do is add all the jars from the report
engine download/reportengine/lib to your apps classpath and remove the
setEngineHome method. Any chance you could post your app?
