hi,

There must be some problem with your java code,because if you are using sax or dom parser properly then there should not be any problem with null values.

For example if you look into these codes

its working fine even with null values,You try to check your code with these

Murugavel,

Could you please explain in little more detail the error condition?

Are you passing an empty value or a NULL value. Possibly you could check for the length of the input before performing any operations on it.

Thanks,

Hi,

I am not giving any input value. If i give any input means it is processing well but if i didnot give means the errror is being thrown. so i want to process the input wat ever it is. If it is null i want the target to be null, if it has a value then i want the value as it is in target. Please help me in this.

Regards,

Murugavel.

Hi,

>> If it is null i want the target to be null,

In the mapping before performing any string operation on that field first check if it is null then return a null value else do the string operation that needs to be performed on that field. This avoids the exception.

For checking if the field is null u can.

1. Check if the length of the field > 0.

2. Chech if the filed == null.

Is the empty input value is as the file level i.e empty file or at the field leve i.e empty field.

also be more specific of your requirement.
