hello,
I am trying to connect to mysql through the DataSource interface. The reason
for this is because I am
writing my own connection pooling mechanism and will be using the DataSource
interface in my connection pool code. I was wondering if anyone had
experience with this. When I try to connect to MySql's MysqlDataSource class
and My config file looks like this:
<!DOCTYPE databases PUBLIC "-//EXOLAB/Castor JDO Configuration DTD Version
1.0//EN"
"http://castor.exolab.org/jdo-conf.dtd";>
<database name="test" engine="mysql" >
<data-source class-name="org.gjt.mm.mysql.MysqlDataSource">
<param server-name="localhost" port-number="" database-name="test"
user="root" password="" />
</data-source>
<mapping href="mapping.xml" />
</database>
I get this error:
[test] Loading mapping descriptors from
file:/D:/castor-0.9.3.9/examples/jdo/mapping.xml
[test] org.exolab.castor.jdo.DatabaseNotFoundException: Nested error:
