使用Glassfish嵌入式德比是否明智?如果是或否,那将是什么原因?
如果我使用Glassfish嵌入式德比,我是否必须配置JDBC连接池?如果是的话,有没有关于它的好教程?因为我一直试图找到一个,但仍然没有运气。
我尝试了解是否应该将我的Web应用程序Embedder Derby或普通Derby用作数据库。
例如,当我尝试使用资源类型 java.sql.Driver
和数据源类名 org.apache.derby.jdbc.EmbeddedDriver
配置JDBC连接池时出现以下错误:

答案 0 :(得分:0)
解决方法是不为Datasource类名添加Driver类名,这非常明显。
