Hello,

Could you please clarify in which Talend version/edition you are? Have you tried to use a tLibraryLoad component to force packaging the lib to see if it works?

Best regards

Hi Sabrina,

Thanks for your reply. I have updated the details above with additional information; including Talend version/edition. We do not have any requirement to use a tLibraryLoad component; so I did not used that.

Best regards,

Hello,

In the module view, all jar relative to your components are installed successfully in studio?

Here is online documentation about: TalendHelpCenter: Installing external modules manually using the Modules view.

Best regards

Yes. The modules for my Talend job components were all successfully installed in Talend Studio. I added additional jar files in the libraries of the routine code; but Talend can't seem to find the class associated to it.

I have also tried the following; but still has similar NoClassDefFoundError:

• Talend Studio menu -- File -> Edit Project Properties -> Build -> Click on Maven -> Click on 'Force full re-synchronize poms'
• Used tLibraryLoad with all the same JAR files added to the routine code.
