I have generated type tree for the following classes

public class LookupDALService {

public TranslationDTO convertToISV(TranslationDTO transDTO1)
{
if(transDTO1.getGender().equalsIgnoreCase("M"))
transDTO1.setGender("Male");
if(transDTO1.getClaimType().equalsIgnoreCase("P"))
transDTO1.setGender("Professional");
return transDTO1;
}
}

package com.test;

public class TranslationDTO {

public String gender;
public String claimType;
public String getClaimType() {
return claimType;
}
public void setClaimType(String claimType1) {
this.claimType = claimType1;
}
public String getGender() {
return gender;
}
public void setGender(String gender1) {
this.gender = gender1;
}

}

And I have used generated type trees as output cards in my map by assigning “SetDataToLookupDALService_ID” to this field of LookupDALService and “SetDataToTranslationDTO_ID” to TranslationDTO.

And used “SetDataToTranslationDTO_ID” value in convertToISV of LookupDALService.mtt

br />

When I run the map I am not getting any errors.
But in the javatrace.log file,I have find following exceptions.
