QuickTip: Resolving Bluetooth Issues With Ubuntu 8.04 LTS

Around a month back I upgraded from 7.10 to 8.04

Most of the stuff worked fine except that my Bluetooth service was broken. I could no longer transfer files from my Nokia 3230 phone to my laptop. The steps defined in my earlier post did not work either and I was always greeted with an “Unable to connect” error. It became terribly irritating after a while and then there had to be a way to get around that.

The way that I suggest is one of the possible many ways, if you find something else please let me know. Read on …

QuickTip: Eclipse on Ubuntu : java.lang.ClassNotFoundException: org.eclipse.core.runtime.Plugin

This problem occurs if you do not have the JRE from Sun, but you are using the JRE from GNU. To get the JRE from Sun execute the following command

$sudo apt-get install sun-java5-jre

now you should get the JRE installed in the directory /usr/lib/jvm

if you hit $ java -version now you should see something like this

java version “1.5.0_13″
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_13-b05)
Java HotSpot(TM) Server VM (build 1.5.0_13-b05, mixed mode)

Now your Eclipse Europa should work without complaining.

Dual Boot Pre-Installed XP with Ubuntu Gutsy Gibbon

Last evening I installed Ubuntu Gutsy Gibbon (7.10) on my Dell Laptop which was pre-installed with Windows XP and it worked like a charm.

Though this is not the first time that I am installing Ubuntu for a dual boot environment however every time I tend to get a bit jittery on what would work and what would not.

Any way these are the steps that I followed which worked for me.

YamiPod: Using iPod with Ubuntu

If you have recently moved from Windows to Linux then one of the things possibly troubling you would be how to synchronize your iPod without the iTunes software.

Well the answer lies in

A relative newcomer to the iPod file management arena is YamiPod.

Download from the project’s website at www.yamipod.com.The file will appear on your disk as a tarball, so first extract the tarball, and then move the yam-linux folder, which is the product of that extraction, to your home folder.

QuickTip: Transferring files between two Ubuntu systems

Easy way to transfer files between Ubuntu systems is by using scp and sftp. The SSH File Transfer Protocol or SFTP is a network protocol that provides file transfer and manipulation functionality over any reliable data stream. It is typically used with the SSH-2 protocol (TCP port 22) to provide secure file transfer, but is intended to be usable with other protocols as well.

STEP I

Make sure that the 2 systems can talk to each other

You will need the network address of both machines - I will call them A and B.

Ping test - using the IP address of B try to ping it from A: From machine A, open a terminal window and type ‘ping’ followed by the IP address of machine B, for example:

ping 192.168.0.1

You should get messages like ‘xxx bytes received from 192.168.0.1 in 8 ms’ - if you get errors, this is your first problem.

If you got no errors, then repeat from machine B, pinging machine A.

Once you are sure your basic networking is functioning correctly, you can go back to setting up your data transfer.

QuickLink: Enabling BlueTooth file transfer on Ubuntu

Recently I came back from a conference on Agile and had to transfer some photographs that I had taken after I had spent some time presenting on the conference. The basic BlueTooth settings on my Ubuntu Fiesty Fawn would not work and had it not been for this great link, I would probably still have been stuck with the photographs on my mobile phone.

With some easy settings mentioned on the page I was able to rapidly transfer files to and from Ubuntu. Cheers!

QuickTip: Setting CLASSPATH on linux

For bash shell:
vhazrati@vhazrati-laptop:~$ export CLASSPATH=$CLASSPATH:/home/vhazrati/bea815/weblogic81/server/lib/weblogic.jar:/home/vhazrati/xebiaprojects/jmsconsole/trunk/target/javax.jms-1.1.jar

For tcsh or csh:
set CLASSPATH = ($CLASSPATH /home/vhazrati/bea815/weblogic81/server/lib/weblogic.jar)

To test

vhazrati@vhazrati-laptop:~$ echo $CLASSPATH

Alternatively you can add the following to your .bashrc

export CLASSPATH=.:/home/vhazrati/bea815/weblogic81/server/lib/weblogic.jar:
