Thank you in advance for taking a look.
Answers to your questions:
Eclipse Juno Version: 4.2.2
AAOD 7.0.1.0804
Teradata jars not required. I am just doing a stock JNDI lookup and you should be able to insert your own DB connection to whatever JNDI DB connection you may have. The "Test" variable is expected to be in the form of "java:comp/env/jdbc/<your_db_here>"
I have set up the JNDI Resources in the tomcat server.xml and context.xml appropriately and know they are working. Tomcat version is 7.0.55 but I don't think that will matter.
Code follows:
package flow;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import javax.sql.DataSource;
