can you post what are the parameter you mentioned in the command prompt?

Have you configured ldap?  If so make sure that the connection to Ldap could be established.

Are you using a 32bit or 64bit JVM?  What heap settings, especially MaxHeap (-Xmx) are you using?

i've not done any ldap configuration.But i'm able to start the cq when i click executable jar file.

Thanks!
