Hibernate error; could not obtain connection metadata: Unsupported feature

Background:

OS: ubuntu11.10

IDE: eclipse-Indigo

DB: Oracle 10g quick edition for Linux

I took the jar package of java used in Windows to connect to Oracle to the current environment, but reportedCocould not obtain connection metadata: Unsupported features

Later, I went online and said it was okay to replace the original jar package for Oracle10g.

Later I called two jar packages and found that the directories in them were different.

Contents of the first jar package: javax, META-INF, Oracle

Contents of the second jar package: META-INF, Oracle
