WebLogic Server 12.1.3 WebSocket Emulation • Browsers and firewalls may not support/permit WebSocket protocol

• WebLogic provides a fallback mechanism to emulate the WebSocket transport behavior

• Client side with JavaScript library - OraSocket.js

• Server side with an adapter to handle HTTP Long Polling

● Developers

● Use the WebSocket API for Java to write your application

● Use the WebSocket JavaScript Object on the client

● Same codebase

● Looks and smells just like a WebSocket application

● Whatever happens behind the scene is not your concern

11


WebLogic Server 12.1.3 - Java API for JSON Processing

• WebLogic Server implementation based on Java EE7 RI

• Standard Java API to generate and parse JSON – Included in Java EE 7

– Included as module with WebLogic Server 12.1.3

• Has an Object model API to represent JSON – Similar to DOM API in XML world

• Has a Streaming API to produce/consume JSON – Similar to StAX API in XML world

Populating a Maven Respository with Oracle Artifacts • Install Oracle-Maven-Sync plugin using

maven install goal

• Execute goal oracle-maven-sync:push specifying which Oracle Home to use

• The push goal searches Oracle Home seeking .pom and matching .location files

• Performs an artifact install using .pom with the physical jar file specified in matching .location pointer

• Can install to local repository or Maven repository manager such as Archiva, Nexus, Artifactory

WebSockets

29


WebSocket Overview What are WebSockets?

• WebSockets are an emerging web technology that provides full-duplex, bi-directional communication channels using TCP connections over the Internet

• Backed by industry standards – The WebSocket Protocol (IETF RFC 6455)

– The WebSocket API defined in W3C HTML5

– (JSR-356) Java API for WebSocket 1.0 and included in Java EE 7

30


History of WebSocket Support

• Adds support for Java API for WebSocket 1.0 (JSR-356) and JSON Programming API (JSR-353)

• Integrates Project Tyrus as WebSocket implementation

• Uses WebLogic core and networking services

• Deprecate weblogic.websocket.* API

12.1.3

• First ever release with WebSocket support

• Custom implementation of WebSocket protocol RFC 6455

• Uses Async features of web container

• Provides WebLogic Server specific API with annotations for development

12.1.2

31

WebLogic Server


WebLogic Server 12.1.2 WebSocket Support

• Custom implementation of the WebSocket Protocol (RFC 6455) – Tested for compatibility using popular open-source compatibility test suite

– Internal benchmark showed high performance and reliability

• Provided a proprietary programming API to develop applications for use with the WebSocket Protocol – Server only, no Java client support

• Deploy as WAR file containing a WebSocketListener implementation

• Client applications access server applications typically using JavaScript from the browser

32


WebLogic Server 12.1.3 Standards Based WebSocket Support with JSR-356

• Java community developed a standard for using WebSocket with Java – Java API for WebSocket 1.0, JSR-356

– Included in Java EE 7 as a core platform API

– Package javax.websocket.*

– Provides both an annotation based and programmatic API

– API supports Client and Server use

• WebLogic Server 12.1.3 supports JSR-356 for WebSocket use – Enables development and deployment of applications using standard WebSocket API

– Applications portable across containers supporting JSR-356

33


WebLogic Server 12.1.3 Bonus JSR-353: Java API for JSON Programming

• Java community developed a standard generating and parsing JSON – Java API for JSON Programming 1.0, JSR-353

– Included in Java EE 7 as core platform API

– Package javax.json.*

– Enables developers to create and parse JSON using an Object Model or Streaming API

– Conceptually similar to XML-P and DOM v StAX XML parsers

• WebLogic Server 12.1.3 also include JSR-353 for developers to use – Inbuilt WLS module, any deployed application can make use of it

– Particularly useful for WebSocket encoders/decoders working with JSON payloads

34


WebLogic Server 12.1.2/12.1.3 WebSocket Differences

WebLogic Server 12.1.2 WebLogic Server 12.1.3

Proprietary API and annotations weblogic.websocket.*

JSR-356 Java API for WebSocket 1.0 javax.websocket.* with annotation and programmatic options

No Java Client API Full JSR-356 Client Support

Custom implementation of WebSocket Protocol listener and runtime implementation

Integrates JSR-356 reference implementation (Tyrus) for high degree of specification compliance and portability

Uses internal Servlet to handle WebSocket handshake and protocol upgrade, binds URI to HTTP or WS explicitly

Tyrus integrated using ServletContainerInitializer and ServletFilter to handle WebSocket handshake with co-existing URI support

Uses Async Web container features of WLS to handle WebSocket messages

WebSocket Messages handled by Tyrus using WebLogic Server network and threading services

35


Happy HTML5 WebSockets

● HTML5 and the Java API for WebSocket ● Enables lots of new opportunities for developing highly

interactive applications and rich user experiences

• Lightweight, fast, easy to program

• Standardizing across the industry

● But ...

● WebSockets are not universally supported across all current environments

● Most browsers support HTML5 and WebSockets - but - not all of them

● Firewalls or proxy servers may block the required frames and protocol


WebSocket Fallback • Provides a behind-the-scenes fallback mechanism to

emulate the WebSocket transport behavior • Server side with an adapter to handle HTTP Long Polling for

WebSocket messages when required

• Client side with JavaScript library - OraSocket.js

● Developers ● Use the Java API for WebSocket to developer your application,

enable fallback via web.xml context-param

● Use the HTML5 JavaScript WebSocket API on the client, Include OraSocket.js on client pages

● Same codebase for native WebSocket Protocol and fallback

● Transparent runtime behavior


WebLogic WebSocket Protocol Performance Scalability, Performance

• Message Echo Benchmark

– WebSocket Clients connect and send messages every second

– Server broadcasts messages back to clients

• Single WLS Server

– Reliably support 60,000 connections

– Throughput measured at ~20,000 messages/second with a 512 byte payload

• Now observing significant increases in message receive rate with 12.1.3 and Tyrus
