Hi all, 

I'm facing the same error. I'm using talend for Big Data enterprise edition 6.3.1. I'm not able to get the export of my jobs as i'm not able to open talend studio. I have attached the error logs.

Hello

What's JDK version you are using? For v6 of Talend products JDKv1.8 is required .

Best regards

When i execute out of Studio (Nexus -> TAC (execution) ) or job builded (execution). But when executed in studio it's ok.

i see somthing importante the subjob jars are not générated in this case.

Thanks in advence.

Hello,

Before building your Job, go to Window > Preferences, select Talend > Import/Export, and then select the Add classpath jar in exported jobs check box to wrap the Jars in a classpath.jar file added to the built Job to see if it is OK with you when do job execution(.bat or .sh)?

Best regards

Thxn for quick answer.

I do find solution by re-exporting jobs with all dependencies and re-build the job master and it's OK ( with nexus and .bat)
