[jibx-users] Problems in unmrashalling without custom deserializer/serializer

[Paras Jain]

Hi,
I am getting the NumberFormat exception while unmarshalling. Root of the problem seems to be empty element
Here are the details

public class MyexampleClass  {
  Integer INTEGER_FIELD;
  Date DATE_FIELD;
...getter and setter methods
}

Binding file is
    <mapping name="EXAMPLE_CLASS" class="examples.MyexampleClass  ">
    <structure name="INTEGER_FIELD">
       <value usage="optional" style="text" field="INTEGER_FIELD"></value>
    </structure>
    <structure name="DATE_FIELD">
       <value usage="optional" style="text" field="DATE_FIELD"
                 serializer="examples.CustomDateMarshallerUnmarshaller.serialize"
                 deserializer="examples.CustomDateMarshallerUnmarshaller.deserialize">
        </value>
    </structure>
   </mapping>
My data file is

<EXAMPLE_CLASS>
<INTEGER_FIELD/>
<DATE_FIELD/>
</EXAMPLE_CLASS>
When I both the fields are empty I get NumberFormatException for input string "" for integer.

But if INTEGER_FIELD is set to some integer it works fine because for Date I have custom marshaller unmarshaller.
Why don't empty tags in case of Integer works even if  I have specified usage="optional" in my binding file
Please suggest me? Help me


Regards,
Paras
