    Read a File of /dev/*

    Hi

    I need to read a file, but this file is written by a driver, for example /dev/myFile.
    I want to read the file with Java, and I have tried with java.io classes, I can read other files, but I can't read myFile, maybe the reason is that the file is always changing with the information of the device.
    I tried with C# and I couldn't either.

    Thank you

    Have you checked the file permissions of /dev/myFile?
    Make sure it has read bits on in order to get it read by your Java code .
