• How to work with application/service level jar dependencies on Talend Route?
  1. We can add external jars using cConfig in Talend esb routes

• There are some Talend components e.g. (cMQConnectionFactory) which installs libraries as internal or external module. When we include jar as external module we faced issue in Talend runtime as it did not include the jars in build path or may not be including in pom dependencies. What is the best practices over here?
  • If you are using cConfig it will not reflect in OSGI bundle or runtime you need to edit route Mainfest

• When you switch talend workspace – you need to import all JAR files, talend settings and everything once more.

Talend DI Questions

• How to build routines from Talend DI perspective
  1. you write all the java code the routines.
  2. Then, you create a fake job with a simple tJava component that imports the routines you want.

  4. In your routines, just use the cConfig component and select the userRoutines.jar file and don’t forget to edit the manifest of your route by selecting it, the right click “Edit Rout Manifest”, then select the userRoutines.jar
