Physical Location of a file in classpath?

1. a file with a given name;
2. the file is located in the file system;
3. the file can be loaded via the classpath;

How can the code figure out the physical location (ie absolute path) of the file ?

(Don't peek if you want to give it a try!)

Answer:

    String filePath = Thread.currentThread()

                           .getContextClassLoader()

                           .getResource(filename)

                           .getFile();

Ubuntu Linux HP Wireless Sorunu

Ubuntu 8.04 + Broadcom Wireless
Posted on March 28, 2008 by Christopher

After a pretty smooth install of Ubuntu Studio 8.04 (Hardy Heron) Beta on my wife’s HP Pavillion dv6000 everything seemed to work well. Everything that is, except for the Broadcom Wireless. I just could not get it to switch on.

When trying to activate the proprietary drivers, the system would tell me I needed to reboot the machine for the changes to take effect. Once booted it would still not be enabled. Both physically and in the proprietary driver screen.

To solve my problem I used the following steps:

1. First off you need to ensure that you have the build essentials package installed so that you can build the b43-fwcutter.

sudo apt-get install build-essential

2. Once that is installed you can download and build b43-fwcutter.

wget http://bu3sch.de/b43/fwcutter/b43-fwcutter-011.tar.bz2
tar xjf b43-fwcutter-011.tar.bz2
cd b43-fwcutter-011
make
cd ..

3. Now we need to download the Broadcom firmware and install it. Note that the “FIRMWARE_INSTALL_DIR” must point to the directory where your firmware directory is. The one I have used below is what it is in Ubuntu.

export FIRMWARE_INSTALL_DIR="/lib/firmware"
wget http://downloads.openwrt.org/sources/broadcom-wl-4.80.53.0.tar.bz2
tar xjf broadcom-wl-4.80.53.0.tar.bz2
cd broadcom-wl-4.80.53.0/kmod
../../b43-fwcutter-011/b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" wl_apsta.o

4. Now simply reboot the laptop and presto… the little wireless light should be blue
