The mapping file:


<many-to-one name="branchTypes" class="com.dairyqueen.dto.BranchTypes">
<column name="BRANCH_TYPE" not-null="true" />
</many-to-one>


public BranchTypes getBranchTypes() {
return this.branchTypes;
}

public void setBranchTypes(BranchTypes branchTypes) {
this.branchTypes = branchTypes;
}


Please help me how to overcome this exception

The mapping file getter/setter methods look correct. Are you certain that the BranchTypes class in your java code is from the com.dairyqueen.dto package ?

yes all the classes are in the com.dairyqueen.dto package only.
