Promblem with jre

I try setup iMS 5.2.

I want execute command "jre -cp "/usr/iplanet/servers/bin/msg/imta/classes/imtaconfig.jar" com.iplanet.msg.imta.config.InitConfig -v -d domain.com -r domain.com -h alfa.domain.com -c /usr/iplanet/servers/msg-internet/imta/config"

And everytime I see error:

java.lang.NullPointerException
