Accessing a Java resource as a file

Here is some quick and dirty code to get access to a resource on the class path as a File object:

URL url = this.getClass().getResource("/the-file.txt");
URI uri = new URI(url.toExternalForm());
File f = new File(uri);

Obviously replace "/the-file.txt" with the actual path to the resource. Note: this is the path on the "class path", not the file system.

Unable to Run Windows Update

I upgraded an old Windows 2000 virtual machine to Windows XP today, and afterwards tried to run Windows Update, but got the following error.

The following updates were not installed:

Windows Genuine Advantage Validation Tool (KB892130)
Update for Windows XP (KB898461)

Since these updated are required to download any further updates (like XP SP3), I was hosed. Well, not quite. After some time with Microsoft support, we did finally find a workaround, listed below:

====================================

1. Please download the file from the following link:

http://download.windowsupdate.com/v7/windowsupdate/redist/standalone/WindowsUpdateAgent30-x86.exe 

2. Save the file to "C: drive".

3. Click "Start", "Run", type: "C:\WindowsUpdateAgent30-x86.exe /wuforce" (without quotations) and then press "Enter" to install the Windows Update engine.

There is a space between "C:\WindowsUpdateAgent30-x86.exe" and "/wuforce".

===================

After that I could run Windows Update successfully.
