Java code to XML schema
Customizations are always optional, and you never need to use a customization file unless you want to change the default BindGen behavior. You can also use the require attribute to control which types should be treated as required values in the XML:.
You can think of custom marshallers and unmarshallers as taking the simpler idea of custom serializers and deserializers to a whole new level.
By default, BindGen generates a schema with nested complexType and simpleType definitions for types that are used only once and separate definitions for types that are used more than once. In this section, you’ll learn how to customize BindGen operation to control the XML representation of data, change the style of names and tutorual, and control some aspects of schema structure.
Jibx binding definition elements: Here is a nice one to start with: This version jix the schema represents the same XML document structure as the Listing 9 schema but includes separate type definitions matching each Java class. Kliver Max 2, 12 72 It also controls the XML representation in that the order in which the values are listed becomes the order in which they’re expressed in the Tutotial representation.
Customizing JiBX binding behavior
Another interesting issue that’s come up for several users in the past is the need to work with multiple versions of XML documents. You can go even further with JiBX by working with the actual binding definitions, which give you control over every step of the conversion process. If you install the sample code elsewhere, you can still use the Ant build.
JiBX , Part 1: Java code to XML schema
Licensed to the JiBX Project for free distribution and use. Working at this level takes you into the internals of the JiBX runtime implementation classes. Non-Java 5 usage The tutorial example code uses Java 5 typed collection and enum features, but JiBX itself is fully compatible with older Java versions.
Consider how the XML structure would need to be different if the key values in the hashmap were other mapped objects rather than simple string values, for instance they couldn’t be expressed in XML as attribute values, for starters.
JiBX is also more flexible than almost all other Java-XML tools, using binding definitions to decouple the Java structure from the XML representation so that each can be changed independently of the other.
If a custom marshaller or unmarshaller class which need not be the same class supports setting the root element name in this way it needs to implement the org.
Improve schema quality with custom conversion of Java data models to and from XML documents. You can also run the entire sequence, from compiling the source code to running the test program, with the custom1 Ant target.
The flexibility of the Venetian Blind style is probably not important if you just plan to use your Java code as the base for any further changes rerunning BindGen each time your code changesbut it can be nice if you intend to use the schema as a basis for further development. Mapping element defines the binding used for every objects within the context.
Bind XML message to Java objects using JiBX – JiBX Binding Tutorial
The binding compiler is included in the JiBX distribution as part of jibx-bind. Hibx can go through the tutorial in sequence using the forward links at the bottom of each page, use the menu to the left to browse by individual page, or use this table of contents to jump directly to a particular section of the tutorial: You can also pass global customizations to BindGen as command-line parameters, without the need to create a customizations file, by using — as a special prefix to the customization attribute value.

If you compare Listing 12 with the Listing 10 sample, you’ll see how the representation has jbix changed by the latest customizations. Sharp observers will notice one difference between the input and output that seems significant, in the item-list portion of the output document, shown in Listing
