Running Cx_oracle under Jython

Not all modules this work with Python in CPython implementation would work on the other implementations. If Such module use the system specific calls, or binds to some. dll/.so file it won't work on the other Python implementation. Cx_oracle is one OS such modules:it binds to Oracle client (there be cx_oracle versions for various Oracle versions and various operational systems).

I Think you should the use of JDBC driver if you want to access the Oracle from Jython. Then you can use the JDBC calls, or use the zxJDBC Jython module that makes JDBC drivers available via DB API calls. I used both JDBC (with zxJDBC ) and cx_oracle in programs the can work from CPython and Jython. To see it on action look to my recipe to dump Oracle DB schema to text
