Hello, How are you? I have just read your project description so I am bidding with the willing wish that I will be the most powerful candidate for your project. I am a senior developer who developed a lot of web application like J2EE. I have 10+ years of experience developing J2EE Web application. As you said before, J2EE web application can be developed with a lot of servers, databases. I kept touch in working J2EE with server like Glassfish server, Tomcat v9,8,7,6 servers, JBoss, Oracle WebLogic. J2EE Web Application has got several ways to structure project like -Spring MVC, Hibernate, Maven, Gradle, WildFly. There are frameworks or tools or libraries package which improve project structure so these help to keep good speed of development. Also many databases including Java DB(network or embedded), MySql, Postgresql, mongodb, Oracle OCI, Oracle Thin can be connected with J2EE Web application. We can connect another db by installing driver of the database. I developed payment system with J2EE Tomcat and Glassfish server and made a lot of accounting system because that has got simple to structure in Java. I have limited chars in bidding text now. Please invite me so that we can discuss more details through chatting. Thanks
