Values of HashMap are overriden

I'm creating a HashMap. While creating it, I can see that keys are assigned proper distinct values, but, after creation, when I iterate it, all the keys are yielding only one value. Below is my code:

public void prepareAccountMap(HashMap<String, Object> masterMap, GAReadConfigType config, Properties prop){
    int count=0;
    for(Map.Entry<String, Object> entry : masterMap.entrySet()){
        String key = entry.getKey();
        keyList.add(count, key);
        count++;
        String childFile = (String)entry.getValue();
        System.out.println("First loop, childFile :"+childFile);
        if(childFile!=null){

            /*
             * 1) prop.getProperty gets the path from properties file
             * 2) config.readConfig reads the xml file and prepares a HashMap
            */
            HashMap<String, Object> tempChildMap = config.readConfig(prop.getProperty(GAConstants.GA_XML_CHILD)+ childFile);

            accountMap.put(key, tempChildMap.get(GAConstants.GA_DUMMY_KEY));
            GAAccountBean beanTest = (GAAccountBean)tempChildMap.get(GAConstants.GA_DUMMY_KEY);
            System.out.println("First loop, key :"+key);
            System.out.println("First loop, bean dimension :"+beanTest.getDimensionsFromXML().trim());
        }
      }
    System.out.println("");
    for(Map.Entry<String, Object> entry : accountMap.entrySet()){
        String key = entry.getKey();
        GAAccountBean tempBean = (GAAccountBean)accountMap.get(key);
        System.out.println("Second Loop, key :"+key);
        System.out.println("Second Loop, tempBean dimension :"+tempBean.getDimensionsFromXML().trim());
    }
}

Below is the console ouput:

First loop, childFile :\Acct_38058226\Prop_66591454\Prof_68497513\NJTReport2.xml
First loop, key :NJTReport2.xml
First loop, bean dimension :ga:visitorType,ga:date
First loop, childFile :\Acct_38058226\Prop_66591454\Prof_68497513\TestReportNJT1.xml
First loop, key :TestReportNJT1.xml
First loop, bean dimension :ga:browser,ga:date

Second Loop, key :NJTReport2.xml
Second Loop, tempBean dimension :ga:browser,ga:date
Second Loop, key :TestReportNJT1.xml
Second Loop, tempBean dimension :ga:browser,ga:date

Since the value stored in HashMap is a bean, I'm printing one property of the bean. Hope I'm clear with my question. If not, please let me know the caveat and I shall fill it.Thanks in advance!!
