AI2 and Hexy getting Google app engine Launcher to run a tinywebdb locally on ubuntu 12.04

Ok.. Going on my last weekday of vacation…;( I woke up way too early this morning, freezing.. The furnace had cut out during the night… ( 3 blinky lights on the XR-90 furnace)… It turns out that it was just a ice clogged input pipe.

Anyway, I’m not as bright eyed and bushy tailed as I would like but lets see how this works setting up the tinywebdb.. The instructions seem pretty clear.

  • Download App Engine for Python

Need at least 2.7 python.

jonasthomas@jonasthomas-Satellite-P305D:~$ python -V
Python 2.7.3

Ok.. need at least pip 1.4. pip is a package manager.

Next is the python-sdk

Instructions say I need to add /home/jonasthomas/google_appengine to my path..
Add this to .bashrc
export PATH=$PATH:/home/jonasthomas/google_appengine
then from terminal did source .bashrc

Ok.. Now here’s where I need to bounce back and forth….
I need to download and unzip

Now this is where things start getting confusing for me…

In the instructions for installing TinyWebDb they say….

After installing it, run the GoogleAppEngineLauncher by clicking its icon

Well after a little bit of head scratching and googling that only applies to Pc and Mac..

But… It appears you can get a launcher according to this

Ok.. I used to have wx installed in my heekscad days but.. I suspect no longer so…

sudo apt-get install python-wxversion python-wxglade
(Yep I needed that.)
svn checkout google-appengine-launcher
cd google-appengine-launcher

Ok.. I got some error messages which are explained here:
So this is what I added and seems to be working.

Sooo… lets see back to here
Supposedly all I need to do is this:

  • In the GoogleAppEngineLauncher, choose File | Add Existing Application . Browse to set the Path to the customtinywebdb folder you just unzipped. Then click the Run button. This will launch a test web service that runs on your local machine.

  • You can test the service by opening a browser and entering “localhost:8080” as the URL. You’ll see the web page interface to your web service. The end-goal of this service is to communicate with a mobile app created with App Inventor. But the service provides a web page interface to the service to help programmers with debugging. You can invoke the get and store operations by hand, view the existing entries, and also delete individual entries

Well… when I do that I got this: Firefox can’t establish a connection to the server at localhost:8080.
I found a rough instructions here.

But I don’t think that’s it… In this post, they talk about a little green button on the Google app engine Launcher…
No green but an exclamation point…
When I check the log I got this.

ohhh… Google is not my friend here, which usually means I did something dumb…. need to retrace some steps here(which is why I like to document this stuff)..
Soo.. At this point I don’t know if the problem is with Google App Engine Launcher, or the tinywebdb.
Soo. I think there was hello world application here:

So… I’m getting the same error message which suggests the issue isn’t necessary with the tinywebdb application…. Soo something is going on with

jonasthomas@jonasthomas-Satellite-P305D:~$ locate

Wrong tree.. I think I found the solution:

Supposedly delete this line will cure the problem….

and…..hrrrrggg. green light is on but when I go to http://localhost:8080/ and still no joy….

Ok… Making progress here…

So basically cd to google_appengine, and ran this and I got it
python –port=8080 –host= /home/jonasthomas/hexy_stuff/customtinywebdb
and answered “Y” to updates…
Ok.. Lets see what happens if I reboot and try the google-appengine-launcher…

Yeh…Ok… I’m calling this success.
Hopefully someone gets something useful out of my pain…
Geeez.. That felt more painful than it needed to be.
