Hi Adam,
Sometimes I find it difficult and I feel that I don't have consistency when it comes to establishing the price I will charge for a software project, what techniques or methodologies do you use in order to estimate this? and after you establish a price do you follow a definided structure to elaborate the offer?
Thanks.
Hi Adam
When running payara-micro/server using micro-profile how do you go about implementing authentication for /health & /metrics, programatically?
The goal is to limit who can see metrics/health status, and log (remote ip) if somebody tries to do it that isn't allowed.
What I'm really interested in is implementing it in a jar that can be added with --addjars. This is meant to be in our payara docker image, so that all the services requires same authentication. Basically to ensure you don't forget to add configuration to your application to enable it.
I am using Java EE 8 code pattern according to this link.

Some of senior senior level java programmer some times provide suggestion need to use Apache - Delta spike for CDI.
I can not understand where Apache delta spike is necessary for this application code (example link).
Can you me a explanation why delta spike is important over CDI2.0(JavaEE8) ?
Note : my understand is apache delta spike is not important for java ee8(wildfy15).

Hi,
does it make sense to hide health checks behind any security? because you want to use them for your services in e.g. kubernetes to restart pods if they get unavailable. I think you only need to hold them inside your network so that nobody can call http://yourserver/health from outside the cluster (e.g. with nginx or other possibilities).
For the metrics there is already a security configuration if you add
<basicRegistry id="basic" realm="MicroProfileMetrics"> <user name="admin" password="adminadmin"/> <user name="nonadmin" password="guest" /> </basicRegistry> <administrator-role> <user>admin</user> </administrator-role>
to your server.xml then only someone who can login as admin can read it. Maybe there is also a configuration for JWT but I didn't found any so far.
Hi Adam,
In order to create multiple services that communicate with each other I need to introduce a gateway like in Netflix Zuul. In Java EE what is the way to achieve that ?
Please can you explain the role of a service registry , and what are the choices in the Java EE plateform.
I struggle to get to deserialize the date from javascript date Object to Java usin JSON-B , so I convert and send it as a String from the Client app. is there a better way do send date Objects wth specific format without the conversion to String.
thanks
