B4J Code Snippet how to connect to a MQTT broker that requires a client certificate

Hi,

I am trying to create a client application for devices with AWS IoT broker.

I think this example could help me but I think I am not doing something right when importing the Bouncy jar.

I have added in the header
B4X:
#AdditionalJar: bcprov-jdk15on-165/

and I have placed the bcprov-jdk15on-165.jar in additional libraries.


I get this error (release mode)
bouncyError.PNG


Obviously, I'm not a Java expert (that's why I use b4x). :p

any help? Thanks!

Thanks Erel, but so I have it in the code
The slash was an error writing the post not writing code in my program

Any other idea?
Thank you.

you will need those to get it running:

B4X:
    #AdditionalJar: bcprov-jdk15on-160
    #AdditionalJar: bcpkix-jdk15on-164
