App versioning with Signature Constraints
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Signed apps require a version number to be provided, see :doc:`versioning`. You can't import two different
JARs that claim to be the same version, provide the same contract classes and which are both signed. At runtime
the node will throw a ``DuplicateContractClassException`` exception if this condition is violated.

**Split your app into contract and workflow JARs.** The duplication between ``contract`` and ``workflow`` blocks exists because you should split your app into
two separate JARs/modules, one that contains on-ledger validation code like states and contracts, and one
