在ubuntu20.04下o2oa提示驱动错误

datsuan

在centos上一直没有问题，但换了ubuntu20.04后，提示以下错误，求解：
Caused by: java.lang.RuntimeException: There were errors initializing your configuration: <openjpa-3.1.0-rafcec21a1d489dff682a3ce7986fac6a1c80e8e0 fatal user error> org.apache.openjpa.util.UserException: The persistence provider is attempting to use properties in the persistence.xml file to resolve the data source. A Java Database Connectivity (JDBC) driver or data source class name must be specified in the openjpa.ConnectionDriverName or javax.persistence.jdbc.driver property. The following properties are available in the configuration: "org.apache.openjpa.jdbc.conf.JDBCConfigurationImpl@eb520c25".

已解决，这是一个乌龙问题：
把其它的数据库的相关数据库配置文件拷到config文件夹下时，没有去掉数据库名称，改为 “externalDataSources.json”导致错误……
