Re: Measure the length of an XML document in bytes

Hi,

I think you should place the folder that contains the class in the 
classpath, not the class itself. Try replacing C:\Header\Utility.class 
with C:\Header\.
>>>package MyPackage;

Also the code suggests that the Utility class is inside a package, so 
you will need to create a MyPackage folder in C:\Header and place the 
class there.

Regards,
George
