Unable to find data source in Liberty Profile server

Recently the data source at my local server have create so much trouble to me. I'm using WebSphere Liberty Profile server in my development. In order to ease my work on deployment into production server with minimum changes as possible, I created a data source at my local server. But the data source doesn't seem function properly. I have the following code that grabs the data source from the server and establishes a connection to database server.

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.sql.DataSource;

datasourceJndi="jdbc/informixDB";
Context jndiCntx = new InitialContext();
           
DataSource ds = (javax.sql.DataSource)jndiCntx.lookup(datasourceJndi);
            
//set the connection.
super.con = ds.getConnection();

The code was not working and following stack trace is being thrown.

java.sql.SQLNonTransientException: J2CA8030E: Unable to find jdbcDriverRef com.ibm.ws.jdbc.jdbcDriver_gen_d3507f1a-ecba-4697-9861-d2fe2c14d742 for dataSource jdbc/informixDB.

It was very hard for me to analyze this problem because there are not much people know there is a lightweight WebSphere Application Server ever exists in this world. And since this is new, the support usually is very limited. I have run out of clues on this issue. The temporary solution for this is to switch back to JDBC connection just for my local development

Class.forName("com.informix.jdbc.IfxDriver");
super.con = DriverManager.getConnection("jdbc:informix-sqli://xxx.xxx.xx.xx:2020/dbname:INFORMIXSERVER=online", "username", "password");
