Adding a RootCA to the java aws iot MQTT TLS 1.2

Hi @Maxels88 ,

RootCA should be loaded into your java keystore by default. So you do not need to explicitly provide java SDK with your rootCA.

Which version of Java SDK you are using and what error did you get? Are you able to run the sample provided? We might be able to analyze more if you provide more information about you issue.

Thanks

I'm currently using jdk 1.0.0_51. When I run the example against the endpoint that I have successfully connected to using python and c, I get the follow stack trace:

I was not aware that java had it's own keystore that I had to manage. I am reading into that now, but that would seem to be the piece I am missing.

From the instructions on README, it shows 'To use the SDK, you will need Java 1.7+.'
I would suggest trying upgrade to jdk1.8 and see if it works.
