Dozer deep mapping not working

Question

I have one object which contain Name

package com.chase.ccs.mapping.dozer.prototype;

public class testingobj2 {

private String name;

/** * @return the name */ public String getName() { return name; }

/** * @param name the name to set */ public void setName(String name) { this.name = name; }

}

i want to map the name object in the collection which contain Name object init. collection is the part of another object

package com.chase.ccs.mapping.dozer.prototype;

import java.util.ArrayList; import java.util.List;

public class tesingobj1 {

private List names = new ArrayList();

/** * @return the name */ public List getNames() { return names; }

/** * @param name the name to set */ public void setNames(List name) { this.names = name; }

}

my dozerMapping.xml is """ com.chase.ccs.mapping.dozer.prototype.testingobj2 com.chase.ccs.mapping.dozer.prototype.tesingobj1 name names[0].fname com.chase.ccs.mapping.dozer.prototype.Name com.chase.ccs.mapping.dozer.prototype.Name, java.lang.String """"

but this is giving me null pointer exception
