Hi,

I am trying to do a POST using Groovy script from Bonita Studio 6 to post JSON to external site. I keep getting following error.

I have added to dependency tab, process dependency wizard, under tomcat WEB-INF and also under lib folder but this error wont go away.

Any thoughts?

ava.lang.reflect.InvocationTargetException  
org.bonitasoft.engine.exception.BonitaRuntimeException: USERNAME=install | java.lang.NoClassDefFoundError: org/apache/ivy/core/settings/IvySettings

Thanks,  
Nitin

Hi Nitin,

Have you checked if you have all the necessary libraries?
