[juddi-Developers] jUDDI ConnectionPool is now a Singleton

[Steve Viens <sv...@attbi.com>]

I've turned org.juddi.ConnectionPool into a singleton by making the
constructor private and adding a static "ConnectionPool.getInstance()"
method that will always return the same 'single' shared instance. I've
also added a new JDBCDataSource class to the org.juddi.util package that
is simply a helper class for obtaining a reference to jUDDI's JDBC
DataSource via a JNDI lookup.
 
Now you can easily acquire a JDBC Connection from anywhere within the
framework by doing something like this:
 
1. Get the value of the "juddi.useConnectionPool" property.
 
  boolean usePool = 
    Config.getBooleanProperty("juddi.useConnectionPool",false);
 
 
2. If "usePool" is true then grab reference to the shared ConnectionPool
instance.
 
  ConnectionPool pool = ConnectionPool.getInstance();
 
3. If "usePool" is false then use the new org.juddi.util.JDBCDataSource
to grab a reference to the JDBC DataSource.
 
  DataSource ds = JDBCDataSource.getInstance();
