How to run sql scripts in order to update a Derby schema from java code?

The derby database installations of our customer sides have different schema versions. E.g. Customer1 has db schema version 4.1.5.0240, Customer2 has version 4.0.1.0330.

According to that version the appropriate sql script shall be run in order to update the schema to next level. This
