Are CvDAO and UserDAO your own classes? Because I'll tell you this: -1 is a perfect valid return value for the read methods of both InputStream and Reader. It indicates that all data has been read, and it's by no means an error. Well, unless you expected more data, in which case an EOFException is the best exception to throw.

Thanks Rob for assisting

This error is not throwing only these classes but all the classes that I try to display are working for a while and then for sometime showing this error.

Thanks again

I repeat my first question:

If so, you must check your methods to see if the -1 reads are really errors or not.
