Schema to XML document by JDeveloper

This tutorial explain creating xml schema from scratch and creating xml document from it as well. Jdeveloper 10g has a very easy visual editor for creating xml schema as well as xml document. It is considered that you have basic knowledge of schema. Here are step by step approach

1.Create new project and them create new XML schema

2.By default, a simple schema header tag  and an example element

3. Here we are going to construct schema for an Order xml document like  Order>>Item_list>>Item . A order will have id,description,shipTo address and list of items. To construct such structure we will have three complex type order_type, item_type and order_list_type. So create order_type complex type by drag and drop Complex Type component and edit properties

4. Now drag and drop sequence component to complex component

5.  now drag and drop element components one by one and edit the properties

6. There will multiple items under an order so we will set “maxoccurrence” property to “unbounded”

7.After creating all required complex type, its time to create root node.

9. Its time to create xml document out of this schema, select new XMl from xml schema option

10. select root name and dept.

11 . Here is default xml document

State Design Pattern by Example

Image
State pattern falls under the category of Behavioral patterns. State design pattern comes in picture when a system’s behavior is depends on its own state or some other resource’s state. If an implementation is depends on the states, we end up with snarl of conditional statement every where in code. A very neat approach to deal with such situation is to separate out every state’s behavior and use them where ever they are applicable. The state pattern allows an object to alter its behavior when is internal state changes . The object is appeared to change its class. State pattern is a way to implement the same. Class Diagram : As above class diagram shows, System class holds state instance. As state of system changes , all handle request delegated to respective State’s concrete implementation. Example : Have an example of Vending machine. Vending machine has following states No Coin Inserted Coin Inserted Dispensing Empty Following diagram explain behavior...

Eclipse command framework core expression: Property tester

Image
Addition to Eclipse command framework series, this post explains use of property tester to control command’s enable/visible properties. In earlier post we have tried declarative way to achieve same thing but property tester gives us more control. Property tester is associated with, tester class which implements PropertyTester.java, a namespace and set of property which it supports. We can refer this property tester using its namespace + a property name. It gives you call back to test() method with property name as parameter inside property tester class. We can configure property tester for type of input parameter. Here is sample declaration of property tester extension point < extension point ="org.eclipse.core.expressions.propertyTesters" > < propertyTester class ="com.example.advance.cmd.EditorTester" id ="com.example.advance.cmd.propertyTester1" namespace ="com.example.advance.cm...

Composite Design Pattern by example

Image
This post explains Composite design pattern with an example. When to use ? – Use Composite pattern when you have treat a collection of objects as they were once one thing. With Composite design pattern it is very easy to simplify operations over collection data structure. It reduces complexity of the code required if you were going to handle collection as special case. How to Use? - The Composite pattern consist of Component, Leaf and Composite Classes as shown below class diagram Component – Component declares the common interface that both the single and composite nodes will implements Leaf – The leaf class represent the singular atomic data type implementing he component interface.     Composite – Composite is an abstract entity which declares common functionality which are needed by concrete implementation for handling collection data. An Example -   Item.java public interface Item {     public double getPrice(); ...
