Thanks a lot,

I tried to separate the command, and everything seem ok.

But I had a problem with the command "addprinc", since the java exec pass to
it like a single string (the command was interpreted like "addprinc
lola@SAKURA.COM" and not like "addprinc").

So, my solution was to create a script with parameter separated by spaces
and call it from Java... lovely.

Thanks a lot

Sounds like exec isn't parsing the string the way a shell would, and
kadmin.local sees a separate "-pw" argument and takes that as an
indication that the principal name is "w". According to http://
(java.lang.String) the string is parsed using a StringTokenizer that
doesn't understand quoted strings in the input.

Probably you want to use the exec(String[]) method instead, and
construct the argument array yourself, either as an array directly,
or by more shell-like tokenization.
