Oracle WebLogic: Guaranteed High Availability

• Newer version of application deployed side-by-side with older version in same JVM

• Clients already connected continued to be served by older version

• New clients connect to newer version

• Test versions before opening up to users

• Rollback to previous versions

• Automatic retirement – graceful or timeout

WebLogic 12.1.2 and beyond

• Unified installation process across all Oracle product stack with OUI

• Unified patching process with OPatch

20

Oracle Universal Installer


Lightweight Development with WebLogic Server

• Download size improvement for developers

• No installer, unzip and go on Win/Linux/OSX

• Start an instance with -Dservertype=wlx to launch without EJB, JMS, and JCA containers

• FastSwap greatly reduces project redeployment requirement when doing iterative deployment

11g Full Distro 11g Zip Distro 12c Zip Distro


Demo: Installing WLS 12c ZIP distro

• Unzip the ZIP file

• Go to the extracted folder using your terminal

• Make sure JAVA_HOME points to a Oracle JDK 1.7 installation directory

• Execute the configure utility – Windows: configure.cmd

– Unix (Mac/Linux): configure.sh

• By the end, it will ask you if you want to create a domain. Say ‘Y’.

• Provide a username and password of your choice

• WebLogic will then start and be accessible from http://localhost:7001/console

22


IntelliJ IDEA

23


IntelliJ IDEA

• IntelliJ IDEA Ultimate is the full-featured edition

• Comes with J2EE 1.4, Java EE 5, Java EE 6 and 7 support

– Includes JSF support

– Includes JSF components libraries support (e.g: PrimeFaces)

• Web Development for other frameworks – Spring MVC, GWT, Vaadin, Play, Grails

• Database Development Tools, UML Designer, Build Tools, JVM languages

• And many other features

24


Configuring WebLogic 12c

1. During install, make sure you select WebLogic support feature

2. Open IntelliJ IDEA

3. Select “Configure”

4. Select “Settings”

5. Filter for “Application Servers” on top left

6. Click on + icon

7. Select WebLogic Server

8. Type the WebLogic Home. 1. Example (Windows) – D:\wls12130

25

Getting ready to develop Java EE applications for WebLogic with IntelliJ


Configuring the Apache Maven Plugin for WebLogic 12c

• Go to the WebLogic Home installation directory. – Example: D:\wls12130

• Go to oracle_common/plugins/maven/com/oracle/maven/oracle-maven-sync/12.1.3/

• Execute the following command: $ mvn install:install-file -DpomFile=oracle-maven-sync-12.1.3.pom -Dfile=oracle-maven-

sync-12.1.3.jar

• Execute last command: $ mvn com.oracle.maven:oracle-maven-sync:push -Doracle-maven-

sync.oracleHome=d:\wls12130\

26


Creating a Web project from WebLogic Maven Archetype

$ mvn archetype:generate -DarchetypeGroupId=com.oracle.weblogic.archetype -DarchetypeArtifactId=basic-webapp -DarchetypeVersion=12.1.3-0-0 -DgroupId=org.mycompany -DartifactId=my-basic-webapp-project -Dversion=1.0-SNAPSHOT

• Open this Maven project on IntelliJ by choosing “Open project”, then select the pom.xml file

Developer APIs – Java EE 6

29

• WebLogic 12.1.1 completed WebLogic Java EE 6 API support

– Servlet 3.0, CDI, Managed Beans, JSP 2.2, EJB 3.1, JAX-WS 2.2

– JAX-RS 1.1, JPA 2.0, JSF 2.0 available in WLS 10.3.4+

• Java EE 6 Makes Development Faster

– Fewer Java Classes, Less Code, Less XML

• With Modern Programming Techniques

– Dependency Injection, Annotations, POJO, REST

my_js_app.showUsers(users);

},

error : function(message) {

console.log("Could not retrieve the list of users”);

}

});

TopLink Data Services in 12c

• Easy to configure JSON/XML access via REST to enterprise data sources

• Declarative: No Java SE/EE development required – Existing JPA apps

• Add TopLink Data Services web fragment to app • Upon deployment, REST interfaces to entities generated using JAX-RS

– Can also generate mapping file from DB, and expose interfaces based on that

– Supports Oracle DB Notifications

• Multiple Data Sources: Relational, NoSQL, Coherence

• Multiple Clients: HTML5/JS, mobile devices, ADF Mobile

• Leverage all of TopLink’s features including TopLink Grid, etc.
