Hi Jody,
Thank you for your reply!
So basically yes, i am using eclipse and servlet in the same process. Let
me give you more details. I am sending the geographical coordinates from
javascript to eclipse using an ajax call to the configured servlet in
eclipse. That means i get the data in the doPost method of the servlet
class and then in order to process the data, i am using the
ServletContextListener's class contextDestroyed method .
I hope i did not confuse you too much. Hang in there, more details are
coming :)
In the contextDestroyed method i am calling a function that handles the
shape file processing. This function is pretty simple, it's the basic load
of the shape file http://screencast.com/t/gNHFueN39aZK that ends with
showMap call.
That one call is throwing the AWT exception which does not allow the system
to turn back in the contextDestroyed method in order to properly destroy
the context of the servlet.
Here are some screenshots:

- the contextDestroyed method with the call to the shapefile function

- the function used to handle the shapefile loading

I might be using a too complicated way to set this up, but i am a beginner
so bear with me.
