I am trying to configure wildfly10 and JDK 1.8.xx.212 for the truststore and following is my configuration in host.xml.

but I see following error.

I have reinstalled jvm to ensure clean installation. However there is no change.
I have copied the stacktrace for the handshaking error at pastebin webpage.
It does seems our certificate gets added initially as per following:

I am facing something similar as I am trying to connect to following URL

However the connection fails with following info.
%% Invalidated:  [Session-3, TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256]
SEND TLSv1.2 ALERT:  fatal, description = certificate_unknown
handling exception: PKIX path building failed: unable to find valid certification path to requested target

However our certificate works properly and I created proper certificate chain. I have tested to the the and looks good.

Thanks Kirk,
Jigsaw vs OSGI gives one more topic for writing(i.e. fighting) what is bundle vs module.


The somebody choose OSGI for the project. That means there is a smart architect sitting there who knows importance of modularity. I believe there must be other supporting frameworks will be used on need basis, and project manager may not aware of it.

And what made you think that learning something new in software industry will reduce job opportunity for you?

I started going through OSGI at later stage of my career and then I am wondering why did I spent learning Struts vs Spring vs Seam. I could have learnt OSGI and keep it using from last 10 years. The framework is cloud agnostic from day one. Thanks Kirk for promoting OSGI concepts further.

The new web 3.0 world of HTML5/javascript/websockets should keep enhancing the same concept. I see small efforts towards it,

Hopefully it will pickup in a short time.

To get true modularity (independent) modules, what kind of data transfer mechanism you do recommend?

Does the book covers this aspect?


Interesting thought, I am inline with you. Modularity is a modularity, what it has to do with language(.Net or Java). But it has to do with framework, to bring smart and average engineer in same page. And the best way of achieving Modularity is through usage OSGI. Does the book follows same root? Do you expand it to explain the usage of AOP in modularity?

As you mention books goes beyond OO concepts. However I assume the nucleus of modularity must be OOP. Do you share same thoughts.

Seems you are creating new patterns in the context of modularity. In that case, I believe the GOF patterns can be applicable in side a module but not between the modules.


This is from your site:
"Whether you’re using OSGi today, getting ready for modularity in Java 8" . So unto what extent book covers java 8 concepts?

For the sack of POC I have used JBoss 7.x(which has OSGI container) and HBase and integrated them. Though for the web application I have not used OSGI, the concept is very valid. You can deploy OSGI in the container and connect with Big Data(I don't know which DB you planning to choose). I choose JBoss as I plan to use it as more of an ESB then just a container. In normal situation Felix will work too.

We are seeking for rookie engineer to join our team to work on HTML5 and jQuery based implementation.

Very interesting. Is there a way to download the book?
