如何在ClientDataSource中设置内存数据库？

Question

First I was using this way how to get connection and all was fine.

con = DriverManager.getConnection("jdbc:derby:memory:datab;create=true");

But now I have to change it to DataSource and how I find out derby had class ClientDataSource for this, but for the hell I can't find out how to setup that virtual DB in JUnit tests.

ClientDataSource ds = new ClientDataSource();
con = ds.getConnection();

Answer 1

Since I found this question during my googling :

The answer is to use the EmbeddedDataSource instead of the ClientDataSource and to keep the "memory:" prefix before the database name

import org.apache.derby.jdbc.EmbeddedDataSource;
...
EmbeddedDataSource ds = new EmbeddedDataSource();

ds.setDatabaseName("memory:" + "datab");
ds.setCreateDatabase("create");
ds.setUser("user");
ds.setPassword("pwd");
