Denali: How to get Dynamic Condition work?

Resolving The Problem

Sample Code:

package com.yantra.yfs.extn;
import com.yantra.yfs.extn.*;
import com.yantra.ycp.wf.server.*;

import java.util.Map;
import java.io.*;
import java.util.*;
import com.yantra.yfs.japi.YFSEnvironment;
import org.w3c.dom.Document;

public class TestDynamicCondition implements YCPDynamicCondition {

/** Implement this interface to create a dynamic condition.
*
* @param env is the environment handle for the execution thread.
* Use this to call an API from this code.
*
* @param name is the name of the condition configured in the database.
*
* @param mapData contains the name-value pair of strings.
* Keys are same as the variables available in condition builder.
*
* @param xmlData contains additional transaction specific data
* available at the time of execution.
*
* @return return true if the condition is met, else return false.

public boolean evaluateCondition(YFSEnvironment env, String name, Map mapData, String xmlData) {
try {
FileWriter fw = new
FileWriter("/tmp/dynamic_condn.fil");
fw.write(" Dynamic condition being executed \n" );
fw.write(" Condition Name is " + name + "\n");
fw.write(" Transaction XML Data is " + xmlData + "\n" );
fw.write(" Map Data is " + mapData.toString() + "\n" );
System.out.println("Hello");
fw.write(" Hold Map Data is " + mapData.get("HoldFlag").toString() + "\n" );

fw.close();
}
catch ( Exception e ) {
System.out.println("Exception");
e.printStackTrace();
}

if ( mapData.get("HoldFlag").toString().equals("Y") )
{
System.out.println("True");
return true;
}
else
{
System.out.println("False");
