DataSource information in Startup Class

Question

Hi,
I have a startup class and I want to access the database using jdbc and get connection
using the datasource. In case of an EJB, the jndi name and datasource name can be
specified in the deployment descriptor. Is there a way to specify this information
in a startup class?
Thanks,
Patrick

Hi Patric,
You may use custom -Dmy.env.param=my.env.value when start
weblogic. Then you can use standart Java API to access system properties.

Hi Sree,
Thanks. Actually, I do have a data access class which does thedatasource lookup
and gets the connection. The startup class just calls the methods in thisclass.
I would like to have the DSN string as an enviroment variable in thestartup class
which can then be accessed in the data access class, something like this
String dsn = "java:comp/env/jdbc/myds"
Any ideas on how to achieve this?
Thanks,
Patrick

Hi Patrick
here is how you do it.
import java.util.Hashtable;
import java.sql.*;
import javax.sql.*;
import javax.naming.*;
import weblogic.common.*;
import weblogic.jndi.*;
public class DoSQLStartup implements T3StartupDef {
private T3ServicesDef services;
public void setServices(T3ServicesDef services) {
this.services = services;
public String startup(String name, Hashtable args) throws Exception {
// Write your startup code here...
Context ctx = new InitialContext();
DataSource myds = (DataSource)ctx.lookup("myDataSource");
Connection conn = myds.getConnection();
System.out.println("Got connection!!!!!!!!!!!!!!!!!!!!");
// do some db work here
return "ok";
