[resolved] Error Could not find the main class

[dpdfr_ag]

Hi,
I have exported a Job created with TIS 4.2.2|r63143.
When I deployed my Job inside my server and when I launch it ( with a cron tasks ) I have this error :

Could not find the main class: projet_albin.my_job.my_job. Program will exit.

That's very strange because when I make the same export with a TOS version, I have no problem when I execute my Job.
Some idea ?
Thanks.

Same here (on 4.2.3) - thanks for the post. I thought I'm going crazy.
I had it exported once and it worked while later exports keep erroring out. The difference was I was only selecting the Unix launcher...

Hi albin
The job is not exported completely, some of class file are missing. To check if the job runs fine in a TIS studio and try to regenerate it again.

Thats all very nice and dandy but what do I do if I don't have TIS???

Same problem on 5.0.2 under windows XP.
Using "All" for "Shell Launcher" option works too on this version, thanks!
