# Setting up code dependencies on a Joblet

If you want to enable your Joblet to call any function in a routine or custom routine jar, you need to set up code dependencies, namely routine or custom routine jar dependencies, on the Joblet.

You can set up code dependencies on a Joblet in the same way as setting up code dependencies on a Job. For more information, see [Setting up code dependencies on a Job](https://help.qlik.com/talend/en-US/studio-user-guide/8.0/setting-up-code-dependencies-on-job).
