Hello all,
I am creating two applications which share an interface, using the current GREEN platform (VDE-GREEN-STM32F7508-DK-CMW1N (0.1.0-RC202111231722)).
If I create a simple ‘ping’ call in my interface, and implement it at the provider side and call it via Proxy, it works perfectly:
/**
* Interface definition of the service.
*/
public interface MyOutput {
/**
* Print a ping.
*
* @throws IOException
* Throws an IOException when the service is not available.
*/
void printPing() throws IOException;
But, if I try to use a method passing a String argument, it fails:
/**
* Interface definition of the service.
*/
public interface MyOutput {
/**
* Print a ping.
*
* @throws IOException
* Throws an IOException when the service is not available.
*/
void printPing() throws IOException;
/**
* Print function.
*
* @param str
* The string to print.
* @throws IOException
* Throws an IOException when the service is not available.
*/
void println(String str) throws IOException;
The following error happens:
userentrypoint SEVERE: Service unavailable: null

userentrypoint SEVERE: Service unavailable: null
So it seems I am violating some kind of rule.
Can somebody help me with this?
Thank you,
Uri
