Loading Application on Device, do I need to 'sign' it ?

Hello there,

 

I am totally new into the mobile development, but an experienced web developer. I have developed a simple ajax application which works great in my simulator.

 

Now, my question is this. In order to get this application on my device, do I need to 'sign' the application? I have checked a bit and found out that to 'sign' an application you have to pay a small fee at RIM, is that correct? Or if this for my own device (i.e. not distribution), can I do this for free?

 

To be perfectly honest, I have tried to load my application using JavaLoader into my device, and when I try to start it I get a message like "Error starting [myapp]. Module [myapp] attempts to access a secure API.

 

Could you please through some light in here?

 

thank you,

 

George

My english is poor.

All applications must be signed to work on a real device.

 

you can buy signed keys from here:

Re: Loading Application on Device, do I need to 'sign' it ?

Yes, that is correct. Any BlackBerry Java application will run in the simulator. Any application that uses a protected API must be signed before it will run on a device.

 

Yes, there's a fee - but you only have to pay once (you can sign millions of applications with the keys you get).

 

Take a look at the online help, there's a lock icon next to any method that requires code signing.
