Subject RE: IBM J9 Personal Profile 1.1 + OSGi + Derby

Thanks Dan,

I had a look at the source code last night and noticed the EmbeddedActivator
instantiates a EmbeddedDataSource which by default uses java.sql.Driver.

I will probably write my own Activator instead. The problem now is the
DriverManager provides static methods to return connections where as we need
to deal with an instance of a javax.sql.DataSource to get connections. The
current Activator instantiates an EmbeddedDataSource and does not need to
retain a reference to it since connections are obtained via the static
DriverManager.getConnection method.

Ideally current EmbeddedActivator needs to do both. I suppose it can check
for the existence of the java.sql.Driver class whether to use a
EmbeddedDataSource or EmbeddedSimpleDataSource. But since the
java.sql.DriverManager and javax.sql.DataSource provided connections in a
different way I'm not sure how to accommodate both?

Any ideas?

Thanks
Paul
