Hi,

Really sorry if I post problem with old issue,

I have error like this :

I check in all forums and read what others have experience this problem and I tried some of solution proposed in there, but nothing helps. I also already try the sequence of unplug --> turn off--> plug while the console is "retrying..."

The funny thing is, I experience this problem either in the SPOTs and also base-station. And it only occurs in Windows (Vista). Another funny thing is, the problem doesn't occur if I restart my Windows, but after running the program, the problem happens again. I'm pretty sure that the cause is in the Windows system. But in what part that I should change in my Windows system?

Any suggestion please?

For some reason when you run SPOTManager, you are getting a different version of ant than the one you are reporting. Not sure why, but see line

Ant Version: 1.6.2 lower than required: 1.6.5

The command executed by Java is reporting 1.6. and not the one you got from shell.

Not sure how this is happening, but it may be interesting to see if you have other versions of ant installed ?

Hi

Today I managed to upgrade this SPOT. I do not know how.
I played around for nearly half a day and did not manage to upgrade.

So i gave it up and took the ones which had the purple firmware already installed.

Today i gave another try and it worked the first time.

Both times i tried it with ant.
Ant resides in the netbeans5.5 directory.

Difference was that in preceeding trials i started the build from Demos/Airtext directory
now i started it from another directory.
But there is no difference in build.xml and build.properties files.

What i also did meanwhile was, but i do not know how often, to install and deinstall usb drivers. Maybe this made the things go.

dwalend$ which ant

but it's the same version as

I didn't see much in the log, but maybe you'll see more.

Isn't there somewhere I can just pick up the .jars and go? I feel like I'm asking my dad for the car keys.

Sun SPOT Software :: RE: Building a jar for the host application

Author: rgoldman
Posted: Thu May 08, 2008 8:53 pm (GMT -7)
Topic Replies: 2

In general it is not possible to make a host jar file that one can click on and have run correctly because the host app needs to be told what port the basestation is located on via a Java system property. Also there is no way (that I know of) to specify the java.library.path in the manifest file that is needed to load the native RXTX library.

If you do "ant -v host-run" you will see the values you need to put on the command line to define the properties java.library.path and SERIAL_PORT.

Then to create a valid manifest file define a new target in your project's build.xml file. Including the Class-Path in the manifest means that you do not need to specify it on the command line.

Code:

Note the names for the SPOT libraries have changed for the upcoming Blue release, so for Blue change the class path value to:

Code:

Let us know how that works for you.

Topic Replies: 2

It's not clear from your message whether you are trying to build a SPOT app or a host app. Also it is not clear what you mean by "the builder", that is what command did you give? Likewise it's important to know what version of the SPOT SDK you are using. So let me take a stab at some help.

For a host app all you need to do is specify the third party jar files in your project's build.properties file:

Code:

user.classpath=/whatever/directory/ksoap.jar

For a SPOT app to have the third party jar deployed to the SPOT you need to use the following:

Code:

utility.jars=/whatever/directory/ksoap.jar

For a SPOT app, if you are using NetBeans, you also need to add the third party jar file to the compile classpath (i.e. <classpath mode="compile">) in the nbproject/project.xml file. If you have modified your project.xml file to use SPOT defined properties then you can add it by putting

Code:

user.classpath=${utility.jars}

in your build.properties file.

It seems to be a stupid question but really i have added third party jar files (ksoap API) in the properties(Class source Path) of my project. When i include it in my class, the builder says package does not exist.

For example.

Hi all,

The internet is a big place and sometimes its hard to find Sun SPOT projects. We've created a unique keyword in order to make it easier to find Sun SPOTs projects. The word is "spaughts." I wanted to remind everyone that you can find videos relating to Sun SPOTs by searching on YouTube.com for the tag "spaughts" Similarly, you can find images of Sun SPOTs in action by searching Flickr.com for the tag "spaughts"

Media tagged with these keywords on either Flickr or YouTube automatically feed into this page http://www.sunspotworld.com/docs/media/index.php. Similarly, RSS feeds of YouTube videos can be found here: feed://www.youtube.com/rss/tag/spaughts.rss and Flickr pictures can be found here: feed://api.flickr.com/services/feeds/photos_public.gne?tags=spaughts&lang=en-us&format=rss_200

In fact, you can find lots of interesting Sun SPOT activities by doing a Google search for "spaughts" http://www.google.com/search?hl=en&rls=en-us&q=spaughts&btnG=Search

To summarize, Sun Spotters use the keyword "spaughts" to tag their stuff on the internet. If you post something about Sun SPOTs and want it to be found by others, you should use the tag too!

You aren't the first to have this problem. See https://www.sunspotworld.com/forums/viewtopic.php?t=1051. As you'll see there, we never managed to work out what was different about his XP setup compared to mine, which doesn't have the problem.

To repeat what I said there:

I start with no basestation connected to my computer, in fact no SPOT at all.
Then I'm doing

cd <my-app>
ant spotworld

I wait for SPOTWorld to come up. I wait for it to give up trying for a basestation. Then I click on "Emulator" and then "New virtual SPOT" and an image appears. Then I click "File" and "Exit". SPOTWorld goes away, the ant script terminates, and the Squawk process vanishes.

Assuming that this exact sequence is still failing for you, then it looks like some environmental difference. Things that occur to me are the contents of .sunspot.properties, your application's build.xml and build.properties files, and the ant version (do "ant -version")? If you could post the contents of these files and the version output it might help... And of course any changes you might have made to the SDK ant scripts.
