Java Source Code / Java Documentation » Database ORM » MMBase » org.mmbase.storage.implementation.database   Source Cross Reference   Class Diagram   Java Document (Java Doc)   java.lang.Object    org.mmbase.storage.implementation.database.GenericDataSource GenericDataSource final public class GenericDataSource implements DataSource(Code) 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. author:    Pierre van Rooden author:    Michiel Meeuwissen since:    MMBase-1.7 version:    $Id: GenericDataSource.java,v 1.16 2008/02/22 12:27:48 michiel Exp $ Inner Class :public static class ConnectionProxy implements java.lang.reflect.InvocationHandler Constructor Summary   GenericDataSource(MMBase mmbase, String dataDir)      Constructs a datasource for accessing the database belonging to the given MMBase module.
