series of commands using commons-exec -

i new apache commons-exec.

is there way can send series of commands remote machine without authenticating each time?

would order:

ssh a@b command1 command2 

but apparently commons-exec needs this:

ssh a@b \n command1 ssh a@b \n command2 

any idea?

try

ssh a@b "command1; command2" 

this common way execute multiple command on remote system via ssh within script. should work case well.
