Whack weather example usage

ste1 · March 20, 2009, 12:12pm

ez all

i’m pretty new with whack and i have some perplexities about the weather example…i built it, run it: now what? how i can use it? i suppose i have to write a client plugin but…

thanks!

Hi, for testing you can use Psi for example, add your weather component in your buddy list and send him a message with a weather station from http://weather.noaa.gov/ (see the attached screenshot).But for a comfortable usage, yeah, maybe you can write a client

I read that the weather example was in a sample folder in the source. I downloaded the source zip and did not find it.

Q: Where are you getting the weather example these days?

Thanks,

Guenther_Niess · June 25, 2009, 1:08pm

You can get it via subversion

svn co http://svn.igniterealtime.org/svn/repos/whack/trunk whack

But currently I think you can’t compile the trunk if you don’t fix some old references. See my attached patch to compile and run the actual revision (11087).

I changed the whack.jar build compile target includes in order to pick up the xmpp classes. That allowed me to use whack.jar in my component project. I hope I’m on the right track…

Thanks!

I rebuild whack.jar from SVN - just needed to modify the build.xml to include more classes in whack.jar.
I got the weather sample to compile against these jars:

commons-httpclient.jar

dom4j.jar

jweather.jar

tinder-1.0.0.jar

xpp3.jar
commons-logging.jar

jakarta-oro.jar

log4j.jar

whack.jar

When I try to run the weather example I get:

Exception in thread “main” java.lang.NoClassDefFoundError: org/jivesoftware/stringprep/IDNA

… 5 more

It looks like the missing class is required by the tinder jar. My goal is to run the weather example.

Woops, sorry - found stringprep.jar to fix my runtime problem

Weather example is running, thanks!

Hi @ayyrk,

Where did you find this stringprep.jar file ?

Thanks in advance.

Guenther_Niess · September 15, 2009, 4:21pm

I fixed the current trunk version of whack for the updated API and libraries.

Got to bump this discussion up.

I just downloaded the whack trunk from svn (rev 12148), it seems I cannot build it using ant.

Oh well, I just downloaded the whole jetty distribution and put each jar inside the lib/merge folder… not sure wether this was a good idea, but it worked.

The Whack 1.0.jar which can be found on this website doesn’t work anymore (missing Log class, at least) - maybe someone should update it?

For this weather example, the jweather.jar was missing, too.

sagar_varma · August 11, 2011, 10:33am

I have another solution for compiling the Whack library.Just download “jetty-all-server-7.0.2.RC0.jar” and add build/ merge and run the ant file. This worked for me and had written a sample external component and thats working fine.

Phil_Scala · April 5, 2012, 12:18pm

Yeah Sagar, I did something similar, except I used the jar’s from the openfire trunk, I had to add the following jars to the build/merge directory like you did:

jetty-server.jar

jetty-http.jar

jetty-util.jar

jetty-webapp.jar

jetty-servlet.jar

compiles now.
