CMP Deployment Error - any help would be greatly appreciated :)

hi all

i'm new to these here forums and i'm also a student currently doing EJB's for my fourth year project and i have a problem when deploying a CMP bean in suns deploy tool:

i somehow managed to accidently try to run the client jar file in the cmd line as i was undeploying the bean in suns deploy tool (i don't know if this caused the problem though), now it tells me every time i try to redeploy the bean:

ERROR - Deploy Application in Domain
! ! ! Operation Failed ! ! !

[ Completed (time = 3,2 sec, status = 13) ]

i even tried to go thru the motions of painstakingly deploying it by hand again
this is driving me nuts

has anyone any idea what is going on, i restarted the JAS and computer several times also and i have no idea what the problem is - keep in mind that i am a student and while the answer may be clearly evident to some, it isn't to me. i also have no idea what exactly the error is telling me, damn ambiguous sun! grr i spent 3 hours trying to solve it in college today

but to no avail

thanks for your help and thanks for reading this

ps i know i'm using basic tools to create the beans but our college budget is squat and i have to make do
