UAC on Windows7

problem:
when starting an application - the UAC are used; when starting a service is run under LocalSystem;
so, when the application is started as a service, then it does not see the mapped devices of the user

what I am going to use
is
java.util.concurrent.locks.Lock

with tryLock() and lock()

java - copy directory

surprisingly copy file in Java <7 copies a file, not a directory

    // Copies all files under srcDir to dstDir.
    // If dstDir does not exist, it will be created.
    public void copyDirectory(File srcDir, File dstDir)
        throws IOException
    {
        if (srcDir.isDirectory())
        {
            if (!dstDir.exists())
            {
                dstDir.mkdir();
            }

            String[] children = srcDir.list();
            for (int i = 0; i < children.length; i++)
            {
                copyDirectory(new File(srcDir, children[i]), new File(dstDir, children[i]));
            }
        }
        else
        {
            // This method is implemented in Copying a File
            // copyFile(srcDir, dstDir);
        }
    }

java - Arrays.asList returns not modifiable AbstractList

Arrays.asList: Returns a fixed-size list backed by the specified array.
so, when calling add() or remove() to the result of Arrays.asList - java.lang.UnsupportedOperationException is thrown


to convert an array to a modifiable List use:

T[] data;

List<T> list = new LinkedList<T>(Arrays.asList(data));
