Java module compilation and deployment in Eclipse Luna

Hi Experts,

We are migrating from PI to PO.

So we need to compile an deploy java modules from PI to PO with latest NWDS (We are using Eclipse Luna for this in PO).

Can you help me on step by step process for this? What steps do i need to follow.

I have .ear file in PI and opened that .ear file in eclipse Luna and when I validated that did not find any errors.

What are the next steps do I need to follow if previous steps are valid?

Thank you.
