Thanks folks, in fact you gave me an idea. It was happening due to space because initially i installed Jboss under program files directory. I moved it to root and and it worked. Although my problem is solved, i would like to know that is there a way i can start my server w/o any errors if it is installed under a directory that has a space in name?
