could not find or load the main class

could not find or load the main class

Hi,
I use Talend without problem for 3 years.
Today, i open TOS, and all my favorites projects disappeared, no problem, i find my project easily in "/usr/local/..."
I open one of my jobs, but when i'm trying to run it, i get this error : 
"could not find or load the main class"
when i build my job, there is no réference to my files in ".jar" file, just : 
META-INF/
META-INF/MANIFEST.MF
Thanks for your help.

Re: could not find or load the main class

Hi,
On which build version you got this issue? What's your OS? Do you make some change on your machine? Is there any error message ? Which is located in <Talend Studio installation path>/workspace/.metadata/.log


Best regards
Sabrina

Re: could not find or load the main class

Hi,
Have you ever upgraded your JDK recently? What's your current JDK version?
Could you please paste the error message in log into forum directly? We cannot see the link of error log you provided on forum.
Best regards
Sabrina
