Im trying to send data from the raspberry pi to my website, where i can then process the data using php and place the data into a database. Im doing it this way to offload some of the work onto the server, rather than doing it all on the PI. I keep running into Connector.open permission error. I have tried adding the HTTP Protocol permission into the API Permissions but I am struggling to get this to work

Here is the code which is causing it:

Code: Select all

HttpConnection connection = (HttpConnection) Connector.open(url);

Error messsage:

Code: Select all

java.security.AccessControlException: 
 - com/oracle/meep/security/AccessControllerInternal.checkPermission(), bci=128

 - com/sun/midp/events/EventQueue.run(), bci=129
 - java/lang/Thread.run(), bci=5

Can someone point me in the right direction to fix this please. Iv been trawling through google and can't find much on it.

Lets start with some code, yours that is, what is "Connector" ?

Also, is this really the way you want to go?, Java has great database access classes.

I would prefer to do it this way as I will be connecting to the internet using a 3g dongle. So am trying to reduce the number of connections where possible.

Here is the code:

Code: Select all

         HttpConnection connection = (HttpConnection) Connector.open(url);
            connection.setRequestMethod(HttpConnection.POST);
            connection.setRequestProperty("User-Agent", "Profile/MIDP-1.0 Configuration/CLDC-1.0");
            connection.setRequestProperty("Accept_Language", "en-US");
            connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
            OutputStream outputStream = connection.openOutputStream();
            outputStream.write(data.getBytes());
            System.out.println("Connection to website success!");
            outputStream.close();
            connection.close();
       
        } catch (IOException ex) {
            System.out.println("Connection to website failed!");
        }
