RE: Master/Slave API

Hi Fabien,

 

I found the reason for the first problem (Couldnt add the specified resources java.lang.NullPointerException). The class NativeExample calls the init(String[] args) method from class AbstractExample. This method calls the init(String[] args, int number_of_extra_parameters, String text) method sending the parameter number_of_parameters (2) as number_of_extra_parameters. I think this number must be “0”, otherwise the method will return MalformedURLException and won’t initialize the arguments.

 

Now with this bug fixed, I receive the following error:

Hi Fabio,

 

I updated the code on the SVN to print a stack trace where you

experience the problem.

 

Could you please update your code and then give me the stack trace ?

 

Thanks in advance,

 

Regards,

 

Fabien Viale
