The document details a case study on the development and operations of a financial web system using Oracle WebLogic 12c by Hirofumi Iwasaki from Rakuten, Inc. It outlines the migration from GlassFish, the requirements for financial systems, challenges faced during implementation, and the choice of architectures and technologies, particularly Java EE and Exadata. The importance of operational efficiency, security compliance, and enhancing system capabilities through robust infrastructure is emphasized throughout the case study.

5 Big Issues to Apply New JEE Architecture

no outsourcing to external SI vendors. (Group All)

the application of this policy.

In Mid 2011, We Didn’t Have WebLogic 12c Yet
 Chart of the mid 2011 Java EE app servers
Vendor App Server EE 5 Servers EE 6 Servers
Open Source GlassFish 2.1.1 3.1.1
Oracle WebLogic 10.3 -
IBM WebSphere 7.0 8.0
Red Hat JBoss 6.0 7.0 (partially)
 We wanted to apply Java EE 6 for our new system, but not released.
 We decided to use GlassFish 3.1.1 until the EE 6 applied WebLogic
(12c) released.

31. 31
Impact of the Migrating within the Project
 Non-Interchangeable Development Code
GlassFish  WebLogic
– Different container behaviors.
– Non Java EE, different each server special APIs.
 Scheduled Impacts for Migrating WebLogic Configurations
– Cluster configurations for high availabilities.
– Other setting adjustments.
– Bug checking and applying patches.
– Connecting Oracle Enterprise Manager.

Non-Interchangeable Point: 1. Container Initialization
 Single WAR including JSF and EJBs
– GlassFish
1. EJB initialize (@Startup)
2. JSF (Servlet) initialize (HttpServlet#init())
– WebLogic
1. JSF (Servlet) initialize (HttpServlet#init())
2. EJB initialize (@Startup)
 Inverse initialization pattern
– Affected for the server initializations.
– Absorbed with the wrapper classes

35. 35
Non-Interchangeable Point: 2. Remote Invocation
 Different EJB remote invocation operations. Wrapped for absorbing.
 GlassFish (5 properties, no security)
Properties prop = new Properties();
prop.setProperty(Context.INITIAL_CONTEXT_FACTORY,
“com.sun.enterprise.naming.SerialInitContextFactory”);
prop.setProperty(Context.URL_PKG_PREFXIES,
“com.sun.enterprise.naming”);
prop.setProperty(Context.STATE_FACTORIES
“com.sun.corba.ee.impl.presentation.rmi.JNDIStateFacto
ryImpl”
prop.setProperty("org.omg.CORBA.ORBInitialHost",
“theservername”);
prop.setProperty("org.omg.CORBA.ORBInitialPort",
“3700”);
Context context = new InitialContext(prop);
ARemote remote
= (ARemote) context.lookup(“java:global/…”);
 WebLogic (4 properties, with security)
Properties prop = new Properties();
prop.setProperty(Context.INITIAL_CONTEXT_FACTORY,
“weblogic.jndi.WLInitialContextFactory”);
prop.setProperty(Context.PROVIDER_URL,
“t3://theservername:7001”);
prop.setProperty(Context.SECRITY_PRINCIPAL,
“weblogic”);
prop.setProperty(Context.SECURITY_CREDENTIALS,
“thepassword”);
Context context = new InitialContext(prop);

Our Requests for WebLogic and Exadata
 For WebLogic,
– Appliance of latest Java EE specs ASAP!!
 We know the WebLogic is the basement of the Oracle Fusion
Middleware, but we want the latest EE for our products.
 Yes, we’re waiting the next WebLogic version supporting JEE7.
 For Exadata
– Make patches easy to operate
 Huge costs for updating quarterly update patch.
 Complicated procedures for non-stop upgrading.
 Hoping for the next generation updating technology.
