[JSch-users] simple mkdir exec command using jsch

[Marot L. <lau...@al...>]

Hello,
 I've got the following jsp that works fine .... but only once ! If y
re-submit the page, code is no more executed (can't see "file already
exists" in the logs).

Could it be some kind of session persistence ?

Thanks
