          Overview<\/h2><\/span>\n

          * Use Data control for external ws<\/p>\n

          Environment<\/h3><\/span>\n

          * JDeveloper 11.1.1.6.0<\/p>\n

          Steps<\/h3><\/span>\n

          * Create a new application and project
          \n* Create Java classes
          \n* Create an EJB ws
          \n* Create a WS data control
          \n* Create a JSF page
          \n* Add data control to the page
          \n* Set the labels<\/p>\n

          Create a New Application and Project<\/h2><\/span>\n

          * Create a new JDev application named WSDataControlApp<\/strong>
          \n– Application package prefix: oracle
          \n– Application template: Java EE Web Application <\/p>\n

          \"\"<\/a><\/h6><\/span>\n
          \"\"<\/a><\/h6><\/span>\n

          * Accept all defaults for the ViewController project:<\/p>\n

          \"\"<\/a><\/h6><\/span>\n
          \"\"<\/a><\/h6><\/span>\n

          * Rename the Model project to EJBModel<\/strong><\/p>\n

          \"\"<\/a><\/h6><\/span>\n

          * WSDataControlApp<\/em>:<\/p>\n

          \"\"<\/a><\/h6><\/span>\n

          Create Java Classes<\/h3><\/span>\n

          * Select EJBModel project.
          \n* Create a new Java class named BatchOrder<\/strong> with package name oracle.model.freight<\/strong>
          \n– Add two properties and generate getter\/setter methods:<\/p>\n

          \r\npackage oracle.model.freight;\r\n\r\npublic class BatchOrder {\r\n    private Long batchId;\r\n    private Long orderedQuantity;\r\n\r\n    public void setBatchId(Long batchId) {\r\n        this.batchId = batchId;\r\n    }\r\n\r\n    public Long getBatchId() {\r\n        return batchId;\r\n    }\r\n\r\n    public void setOrderedQuantity(Long orderedQuantity) {\r\n        this.orderedQuantity = orderedQuantity;\r\n    }\r\n\r\n    public Long getOrderedQuantity() {\r\n        return orderedQuantity;\r\n    }\r\n}\r\n<\/pre>\n
          * Create another Java Enumeration class named FreightDestination<\/strong><\/p>\n
          \r\npackage oracle.model.freight;\r\n\r\npublic enum FreightDestination {\r\n    LOCAL(1.0),\r\n    REGIONAL(2.0),\r\n    NATIONAL(3.0),\r\n    INTERNATIONAL(4.0);\r\n\r\n    Double factor;\r\n\r\n    private FreightDestination(Double factor) {\r\n        this.factor = factor;\r\n    }\r\n\r\n    public Double factor() {\r\n        return this.factor;\r\n    }\r\n}\r\n<\/pre>\n
          * Create another Java Enumeration class named CustomerCode<\/strong><\/p>\n
          \r\npackage oracle.model.freight;\r\n\r\npublic enum CustomerCode {\r\n    PLATINUM(20D),\r\n    GOLD(10D),\r\n    SILVER(5D),\r\n    BRONZE(2D),\r\n    OTHER(0D);\r\n\r\n    Double factor;\r\n\r\n    private CustomerCode(Double factor) {\r\n        this.factor = factor;\r\n    }\r\n\r\n    public Double factor() {\r\n        return this.factor;\r\n    }\r\n\r\n    public Double calculateDiscount(Double originalPrice) {\r\n        return (originalPrice * factor) \/ 100;\r\n    }\r\n}\r\n<\/pre>\n
