2.0.7).
Demonstration code :
-------------------------
[M.java]
import com.ibatis.sqlmap.client.SqlMapClient;
import com.ibatis.sqlmap.client.SqlMapClientBuilder;
import java.io.*;
import java.util.*;
/**
* Test for bug in iBatis DBL 2.0.9.
*/
public class M
{
public static void main(String[] args)
{
System.out.println("Testing iBatis DBL 2.0.9 bug : ");
System.out.println("If you run this program with iBatis 2.0.7 it " +
"will return result, if you run it with iBatis 2.0.9 it will " +
"return null.");
try
{
String mapFile = "DB_Config.xml";
Reader reader = new FileReader(mapFile);
SqlMapClient mapper = SqlMapClientBuilder.buildSqlMapClient(
reader);
HashMap m = new HashMap();
m.put("name", "Am");
Map result = (Map)mapper.queryForObject("selectAccount", m);
System.out.println("Result = " + result);
}
catch (Exception exc)
{
exc.printStackTrace();
}
}
