Dear ALL,

Many thanks for your great work in SDN controllers.

I hope to help me answering these two questions:

Priority 1:

1- This is specific question: I follow your workshop in ODL Application tutorial, so I ran into a failure in the building process of excersice 3, I tried it many times. I copied the same code on the website.. and used mvn clean install, please see attached image.. I hope to help me fix this problem..

Priority 2:

2- This is general question: My background in JAVA is basics. So What kind of material: books, or websites, recommend me to explore to catch up learning ODL App development.

Your help will assist me a lot.
Many thanks in advance for your help

Best Regards
