The problem rises in a complex program. It is simplified and rebuilt in Jupyter now.
It has three cells.
Cell 1: import package
Cell 2: make an access to mysql through Jaydebeapi
Cell 3: call a function in Jars.
when runngins cells in the order: Cell 1, Cell 2 and Cell3
Cell 2 works well, but Cell 3 does not.
A JVM has was created in Cell2. So in Cell 3, the jar_path and jar_dependency_path can not be add into the JVM, which lead into jpype.JClass() can not find class.
By now, I solved the jpype.JClass() problem by adding jars into Environment Variables, but i don't know how to add dependency_path into Environment Variables.
when running cells in the order Cell 1, Cell 3 and Cell 2
Cell 3 is called before Cell 2, so it can create a JVM with all jars and dependency it needs. But Cell 2 can not run. I think it has the same problem in the above.
How can I fix the problem. Thanks a lot.

I want to use jaydebeapi and jpype both in a right way.
