设置 WSO2 ML 与 WSO2 DAS 之间的集成

Question

我尝试使用 WSO2 DAS 配置 WSO2 ML，将此数据源指向同一个 postgreSQL 数据库：

ANALYTICS_FS_DB

ANALYTICS_EVENT_STORE

ANALYTICS_PROCESSED_DATA_STORE

但是当我启动 WSO2 DAS 时，我看到了这个错误：

有什么想法吗？？

Answer 1

这可能是由于您复制到 repository/components/lib 目录的 jdbc 连接器版本不受支持。

我已尝试重现您的问题，但未能成功。我的情况没有错误。

我使用的版本如下

postgresql 9.4
connector postgresql-9.4.1208.jre7.jar
