Class GenericDataSource

java.lang.Object
  org.mmbase.storage.implementation.database.GenericDataSource

All Implemented Interfaces:

DataSource

public final class GenericDataSource

extends Object

implements DataSource

This class functions as a Datasource wrapper around the JDBC Module. It is intended for use when MMBase runs outside an applicationserver, or when the server does not (or poorly) support pooled datasources. I can also be used by older systems that use the JDBC Module and do not want to change their configuration. Note that the JDBC Module will likely be fased out as a module at some point in the future, with code and supporting classes to be moved to this class instead.

MMBase-1.7
