Validation of XML file

Hi everyone,

I have written a function to check the validation of XML file. In the IDE (Forte for Java) my program works. This means, an error message will occure, if the xml file is not valid.

I created a Jar File for my program. I am now in trouble, since my program shows an error message every time, when I tried to open a xml file. Even that xml file is valid.

Enclose you can see my program code.

Thanks for your help
