I have the following code in my test class:

public static void main(String[] args)
{
DataSource ds = null;
//String line;

String pSQL = "SELECT ";
pSQL = pSQL + "    * ";
pSQL = pSQL + "FROM ";
pSQL = pSQL + "    Product ";

String pDatasource = "java:TeradataDS";

try
{
// Load the Teradata Driver
Class.forName("com.ncr.teradata.TeraDriver");
}
catch (ClassNotFoundException e)
{
System.out.println(e);
}

try
{
Context c = new InitialContext();
ds = (DataSource) c.lookup (pDatasource);
//"java:TeradataDS"
}
catch (Exception e1)
{
System.out.println("Error finding DataSource: " + e1);
}
try
{
Connection conn = ds.getConnection();
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery(pSQL);
}
catch (Exception e2)
{
System.out.println(e2);
}
}

It is failing on the lookup of the DataSource with the following
message:

Error finding DataSource: javax.naming.NoInitialContextException: Need
to specify class name in environment or system property, or as an
applet parameter, or in an application resource file:
java.naming.factory.initial
java.lang.NullPointerException

Am I missing some kind of supporting file?  I have an XML file with my
datasource in my JBoss directory.
