Question

我下载了 Liferay-7 Tomcat软件包并使用了Oracle 11g数据库。我尝试添加 ojdbc6_g.jar，ojdbc14.jar 和 classes12.jar 但没有任何效果。每次因为不兼容的hibernate方言而得到NullPointerException。

Answer 1

Liferay7 CE不支持oracle（和其他商业dbs）。检查this article和支持的dbs列表的引用以及再次添加oracle支持的方法，或者尝试支持商业数据库的Liferay dxp。

Answer 2

您可以实际使用其他数据库，但需要自定义实现。查看本文了解oracle数据库。它对我有用。 https://www.dontesta.it/en/2016/04/13/liferay-7-ce-how-to-add-support-for-oracle-db/
