CAVERNsoft's Java interface

CAVERNsoft's Java interface is a Java base interface it takes command for the Via Voice and sends the command to the SGI/Unix using Java Server. On the SGI side CAVERN_voiceRecog_c class can be use to send and receive cammand for Java Server. The CAVERNsoft's Java interface get the voice command from Via Voice using speech Engine , and compare the Grammar if it matches any of the choices then it invoke the Java Server send function, which send command to SGI/Unix.

CAVERNsoft's Java interface application :

Host is the mechine that is running the Java Server.

Client is the mechine that is curently logon to the Java Server. NOTE Client can be any mechine at any monent, deponding which mechine you want to comunicate with Java Server.

Status tell the user, if the Java Server is on standby mode or is it running.
