To get started using JiBX, you just need to download the distribution zip file from and the offline version of this documentation, also included in the distribution. JiBX Tutorial, JiBX Example, JiBX Binding Example, JiBX jars download, jibx xml to java object, More info on these can be found in the JiBX documentation. You’ll end up with a directory named jibx, which contains all the JiBX JARs, documentation, examples, and even the source code.

The tutorial download includes an Ant build. Schema allows you to reuse definitions only if they’re global. JiBX is especially convenient jivx you want to develop a schema definition quickly for data exchange without needing to learn a lot about schema. BindGen uses default behaviors which will give good XML structure for most data models – but if the default generation is not satisfactory for your needs you can easily customize the generation handling at every level, with features such as:.

You can see the schema documentation in Listing 2 for each field with a Javadoc in Listing 1and for each global type corresponding to a class with a Javadoc. Either way, you also get a binding definition that lets you use JiBX to convert between the Java code and XML documents matching the schema definition. Now download the tutorial sample codedocumentatoon provided as a ZIP file. Along the way, you’ll see how JiBX adds value to your generated schemas by leveraging your investment in Javadocs to document the schema definition automatically.

JiBX , Part 1: Java code to XML schema

Java names customarily use a “camelcase” style: Binding Definition Binding Tutorial A basic binding. Listing jbx shows the same customizations as Listing 16restructured to use this alternative approach:. In this case, the nested style results in a schema with just three global definitions: So far, you’re only working with a single schema definition, so this very simple form of customization can be used.


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 You can also customize CodeGen’s handling of specific components within a schema definition, including both global definitions and items embedded within the global definitions. Schemas of the type shown in Listing 14called “Venetian Blind” style schemas, are popular for use with complex XML structure definitions.

This second approach works fine for normal data classes, but you’ll still need to supply a factory for any interface or abstract classes which can never be constructed directly.

If you want to set a customization that takes a list of multiple values, use commas rather than spaces as separators between the individual values. If you want to duplicate the effect of the supplied Ant bindgen target, you also need to pass the root directory for the source files of your classes in the command line.

If you install the sample code elsewhere, you can still use the Ant build. The JiBX documentation provides full details on all these customization options, along with more examples of code generation from schema. For this tutorial’s purposes, you’ll keep things simple and just run the binding compiler through Ant.

Definition details Definition contexts. The color coding in the diagram shows how the three parts interrelate. CodeGen Schema Datatype Handling.

When a new instance of the class is needed during unmarshalling, JiBX uses that no-argument constructor to create the instance. The generated code for both of these instances is shown in Listing 2.

This provides a tool to generate a set of Java classes and a corresponding binding definition from a documetnation. The Listing 5 customization consists of a single, unnamespaced schema element with several different attributes giving the specific customizations to be applied. In this tutorial, you’ll see how to apply the second type of generation: But enterprise data-exchange schemas doumentation include specialized components that may not be appropriate for particular applications using those schemas, and these schemas are typically not under your control.

Whether you’re using JiBX directly, with a binding definition you’ve constructed on your own, or using one of the generator tools to create a binding, you’re going to need to go through certain steps every time you build your application:. The codegen target runs CodeGen using defaults, compile compiles the generated code and test code, bind docukentation the JiBX binding, and roundtrip runs the test program on the sample documents.


Finally, you need to list the docimentation class es you want used for generation.

JiBX: Getting Started with JiBX

There are also some cases where the Java value names used by CodeGen don’t work well. Start from Code Start from Code. For more details of using JiBX with existing Java code, including full details of the customizations structure, see the Start from Code section of this documentation.

If you’re starting from existing Java code, you documenttation use the BindGen tool included in the JiBX distribution to automatically generate a binding definition and corresponding XML schema definition from your code. Using customizations in this jlbx allows you to simplify your data model without touching the supplied schemas. There are also convenient examples to help get you going, in four flavors: The set of customizations to be applied are passed to BindGen as an XML document, with nested elements that mirror the structure of your Java code.

Marshalling is the process of generating an XML representation for an object in memory, potentially including objects linked from the original object. You’ll look into those later in the tutorial. You’ll need to install JiBX before documenhation with this tutorial. Part 2 covers the flip side of starting from XML schema definitions and generating Java code.

An example earlier in this tutorial showed some simple CodeGen customizations.
