Datasource without J2EE/JNDI - just J2SE

Question

I'm writing a small program that work quite well with ResultSet but I would like to add pooling conections and a serialized RowSet, so I would like to replace DriverManager with DataSource.
But every thing in the doc's drive me to JDNI and J2EE and I don't want to.
I'm working with J2SE and my appa should be capable to run in very small machines (Pentium 200 MHz, 32MB, 6 GB).
I don't want to start an JDNI SPI (just like RMI, LDAP or anything else)
So, can be made javax.sql.Datasource to work without using JNDI?

Answer 1

Absolutely.
Like yourself I write non-web/j2ee apps and would like to use the DataSource/ConnectionPoolDataSource interfaces.
All that a JNDI implementation does is to call a object factory (passing DataSource configuration details like driver,url,logid,password...) which instantiates a DataSource instance, configures it and passes it back to you. Now you can do all that in your code.
I use Sybases DataSource and am in the process of developing my own Connection pool using Jakarta Pool and the Sybase Pooling classes.
Heres what I have to do to create a DataSource instance:
DataSource ds = new SybDataSource();
ds.setServerName(machine);
ds.setDatabaseName(database);
ds.setUser(logid);
ds.setPassword(password);
ds.setPortNumber(Integer.parseInt(port));
return ds;
Connection c = ds.getConnection();I typically develop Tomcat apps and so to keep my coding techniques similar, I decided to retain JNDI for non-web apps. This involves writing a JNDI SPI, which is no big deal. The benefit is that I have the same configuration techniques (XML files) the same ServiceLocator pattern to get DataSources by name, and the same code in web or non-web apps.
