It is simple to use, easy-to learn for web developers both newbie or expert in Java/EJB server side programming languages as well an IDE such Eclipse with NetBeans plugging tool kit (NPP).It does not support any other language that I am aware of which can be used along this product like JSP / Servlet etc., it also lacks some useful plugins compared its competitor products e g OpenLogic OAMOELite Pro plus has more features supporting EJBs 3+. Lack compatibility between different versions but there should have been upgrade paths from earlier version when they update their newer ones so user don't face problems during migration process.- The price tag was quite cheap compare others available online at time:- There are many free open source options out already including Tomcat - you might want do your own research before deciding if what's better suitable then Lena depending upon where exactly did u r requirements lie-. Easy way forward would've made me go through my old code without much issues faced till now using lena instead than doing manual work comparing all existing solutions we had around us while working previously I like that it is secure (using SSL). It has many options to customize for your needs, such as using more than one email server if you have multiple domains or other applications in use at once. We are able to do everything we need with this software without having problems because of its high security features! No issues so far from our end when used daily by employees who work remotely around-the clock throughout all year round.
