INTRODUCING THE TECHNOLOGIES

15


ORACLE JET

• Oracle JET is targeted at intermediate to advanced JavaScript developersworking on client-side applications. It's a collection of open source JavaScript libraries along with a set of Oracle contributed JavaScript libraries that make it as simple and efficient as possible to build applications that consume and interact with Oracle products and services, especially Oracle Cloud services.

16


ORACLE GLASSFISH

• GlassFish is the reference implementation of Java EE and as such supports Enterprise JavaBeans, JPA, JavaServer Faces, JMS, RMI, JavaServer Pages, servlets, etc. This allows developers to create enterprise applications that are portable and scalable, and that integrate with legacy technologies. Optional components can also be installed for additional services.

18


ORACLE MYSQL

• MySQL is the world's most popular open source database. With its proven performance, reliability, and ease-of-use, MySQL has become the leading database choice for web-based applications, used by high profile web properties including Facebook, Twitter, YouTube

19


THE TRANSITION

• Oracle Database to MySQL

• Weblogic to GlassFish

20


DDL SCRIPTS


• Weblogic–Weblogic-application.xml– IdentityProvider: Weblogic Users

–No Need for EJB references in web.xml

• Glassfish–Glassfish-application.xml– IndentityProvider: JDBC Security

–Needs EJB references in web.xml

– Security Roles Mapping in glassfish-web.xml

–Remove some libs from ear file• zip -d SdcRestServices.ear lib/*• zip -d SdcRestServices.ear adf/*
