Little Ken Robot

Found this on Guardian Blog,

The Guardian Robot can respond to your daily twitters, do sentiment analysis and know if the twitter message is sad or happy. Pretty cool ya.

Its main components are Java as programming language, some servos, PIC and others. The code can be found here. I definitely take a look and explore my own possibilities.

Here’s a video of guardian robot in action:

Im trying to put my java app online. One example I did up is the following:

http://137.132.146.70:8080/tts/WebStartClock/clock.jnlp

The above is tried and tested. Its a freetts web clock that speaks the time.

However, you do need java on the machine to do the web app.

Currently, Im trying to do up my own app to put up online. Using the above as example, i included my jar files, etc. and i came across this error:

unsigned application requesting unrestricted access to system

Doing a few search online, i came across the solution. which was to sign your jar files using jarsigner. Hm. you can test if you can run jarsigner by running this in your command prompt.

>jarsigner.

If its not found, either 1) download java jdk 2) if you already have the jdk, include the bin directory to your path. (you can check if you have the jdk by searching for jarsigner in your computer)

To sign the jar file: below is the command

jarsigner -keystore C:\working\mystore -storepass myspass
-keypass j638klm -signedjar sbundle.jar bundle.jar jane

where j638klm  is the password and jane is the user. a more detailed document can be found here.

Hope this helps someone. =)
