Unable to create Endeca Application -

i have installed endeca ( in linux ) , trying create application. on trying initialize services getting error follows

caused com.endeca.soleng.eac.toolkit.exception.eaccommunicationexception com.endeca.soleng.eac.toolkit.application.application setdefinition - caught exception while defining application 'mediastoreen'. caused com.endeca.eac.client.eacfault sun.reflect.nativeconstructoraccessorimpl newinstance0 - null

i checked application logs & found more info on error, follows

i understand error, don't know can resolve it. guidance highly appreciated.

to work around problem, create of state folder in platformservices/workspace

now remove state folder & seek initialize services.

doing resolved problem. not sure why error occurred. nice if 1 tell cause of issue.
