Deploy Oracle JET Application to Weblogic Server

Arda Eralp
Principal Consultant

Step by step create sample Oracle JET application, built as .war file and deploy it to Weblogic Server.

Step 1: Install Yeoman
nodejs is prerequisite (https://nodejs.org/en/download/)
npm install -g yo
npm install -g generator-oraclejet

Step 2: Gerenate App with using Yo
yo oraclejet DemoApp --template=navbar


Other Yo Templates:
yo oraclejet app1 --template=blank
yo oraclejet app2 --template=basic
yo oraclejet app3 --template=navbar
yo oraclejet app4 --template=navdrawer

Step 3: Install Grunt-War
Change to the project folder and then install the grunt-war plugin same as before:
npm install grunt-war --save-dev

Step 4: Creating War.js file
scripts/grunt/config/war.js

module.exports =  {
  /*
   * Build a WAR (web archive) without Maven or the JVM installed.
   *
   * Template strings in the <%= %> tags are set in the data section of Gruntfile.js,
   *  or you can hardcode the strings here instead
   */
      
        target: {
          options: {
            war_dist_folder: '<%= distdir %>',      /* Folder to generate the WAR into, set in data section of Gruntfile.js */
            war_name: '<%= appname %>',            /* The name for the WAR file (.war will be the extension) */
            webxml_webapp_version: '2.5', /* I needed this older version for JCS-SX */  
            war_extras: [ {filename: 'grunt-war-credits.txt', data: 'This line will appear in the file!\n see http://likeahouseafire.com/2017/08/09/updated-using-grunt-to-create-war-jet3x/ '},
                          {filename: 'WEB-INF/weblogic.xml', data: '<?xml version="1.0" encoding="UTF-8"?>\n<weblogic-web-app xmlns="http://www.bea.com/ns/weblogic/90" xmlns:j2ee="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.bea.com/ns/weblogic/90 http://www.bea.com/ns/weblogic/90/weblogic-web-app.xsd">\n  <jsp-descriptor>\n    <keepgenerated>true</keepgenerated>\n    <debug>true</debug>\n  </jsp-descriptor>\n  <context-root>/<%= appname %></context-root>\n</weblogic-web-app>'}],
             /* the war_extras are extra files to be generated, needed since grunt-war doesn't create a weblogic.xml */
             /* also notice that we're using the <%= appname %> variable in there */  
            webxml_welcome: 'index.html', /* to point web.xml to the default page */
            webxml_webapp_extras: [ '<login-config />\n', '<session-config>\n    <session-timeout>\n    30\n    </session-timeout>\n</session-config>\n' ]  
             /* some extra settings for web.xml to work with JCS-SX */
          },
          files: [
            {
              expand: true,
              cwd: '<%= appdir %>',             /* find the source files for the WAR in the /web folder, set in Gruntfile.js */
              src: ['**'],
              dest: ''
            }
          ]
        }
};

Step 5: Modifying Gruntfile.js

'use strict';
var path = require('path');
module.exports = function(grunt) {

  require('load-grunt-config')(grunt, {
    configPath: path.join(process.cwd(), 'scripts/grunt/config'),
    data: {
      appname: path.basename(process.cwd()),  // same as project directory name, accessible with '<%= appname %>'
      appdir: 'web',  // accessible with '<%= appdir %>'
      distdir: 'dist'  // accessible with '<%= distdir %>'
    }
  });
  grunt.loadNpmTasks("grunt-oraclejet");
  //grunt.loadNpmTasks("grunt-war");
  grunt.registerTask("build", "Public task. Calls oraclejet-build to build the oraclejet application. Can be customized with additional build tasks.", function (buildType) {
    grunt.task.run([`oraclejet-build:${buildType}`, 'war']);
  });
  grunt.registerTask("serve", "Public task. Calls oraclejet-serve to serve the oraclejet application. Can be customized with additional serve tasks.", function (buildType) {
    grunt.task.run([`oraclejet-serve:${buildType}`]);
  });
};

Step 6: Grunt Build
grunt build:release

Step 7: Deploy to Weblogic

Step 8: Test
