Trouble running Twister: bfs

[Saayan]

Hi,

I got Twister running successfully thanks to your help earlier. First
I tried running the wordcount example a few times.
Every try was a success.

Next I tried the bfs example. This time I was faced with a problem.

I followed the exact procedure as mentioned in the readme file under
bfs. First I built and copied the jar file into the apps
directory under the twister folder. Following is what I encountered
after that:-

By the way I am running Twister on a single machine under Ubuntu
10.10.

Following are the specs and details of the machine on which I am
running Twister:

Dell laptop with i3 Dual Core (4 threads) 2.27GHz under Windows 7
Twister running under Ubuntu 10.10 on VMware player with Windows 7 as
host

Java version:-

please make sure NaradaBrokering and Twister Daemons are successfully running.

Or try the newest version to see if you meet the same problem.

Hi,

Thanks for the response - however when I try Twister 0.90 I again get the old error - this time the .bashrc has the line (suggested by you earlier) commented out as shown below.

Hi, Saayan,

We ran Twister successfully in many different environments, including ubuntu.

So I guess the problem you meet is just a small one.

The error is simple, that is the script cannot find the Twister-0.9.jar.

firstly do ant, make sure you have the jar package under $TWISTER_HOME/lib,

then start NB or ActiveMQ

After configuration, cd to $TWISTER_HOME/bin/, then execute ./start_twister.sh

see if this works.

You can also do echo in start_twister.sh to see if classpath is correct.

If it still can not work, next time you need provide me what you have
configured, what you have executed in detail.

Then I can help you to see what is happening there.
