It's a answer of my question.
I missed to call CSVParser.readColumnNames().
---
import java.io.*;
import org.apache.turbine.util.*;
class CSVExample
{
public static void main(String[] args) throws FileNotFoundException, IOException
{
TurbineConfig tc = new TurbineConfig(".","TurbineResources.properties");
tc.init();
if (args.length < 1)
{
System.out.print("Usage: java CSVExample <csvfile>");
System.exit(-1);
}
FileReader fr = new FileReader(args[0]);
CSVParser csvp = new CSVParser(fr);
csvp.readColumnNames();
while (csvp.hasNextRow())
{
ValueParser vp = csvp.nextRow();
System.out.println(vp.get("USER_ID"));
System.out.println(vp.get("FIRST_NAME"));
System.out.println(vp.get("LAST_NAME"));
}
}
}

ex.csv
---
USER_ID, FIRST_NAME, LAST_NAME
1, Foo, Bar
2, Spam, Eggs
