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 codegen target runs CodeGen using defaults, compile compiles the generated code and test code, bind compiles the JiBX binding, and roundtrip runs the test program on the sample documents.
The bytecode enhancement is done by executing one of the JiBX components the binding compiler after documfntation Java classes have been compiled. In documentatjon section, you’ll learn the basics of customizing CodeGen to control the structure of the code generated from a simple schema.
This is found in the starter directory off the installation root. Second, you can choose either to list the values you want to include in the XML representation for a class or to list the values you want to exclude. Listing 6 gives a simple example:. One part of the association is fixed, though: BigInteger is used to represent an xs: The BindGen documentation in the JiBX download includes an example showing how customizations can supply BindGen with the equivalent of typed collections when you use pre-Java 5 code.
Listing 15 shows a definition from one of the other schemas referenced by TimeCardwhich makes a good sample to demonstrate customization of individual components.
The generated code consists of five classes, corresponding to the five global type definitions in the Listing 1 schema. All the examples are set up to use the Ant build tool.
JiBX – Plugin Documentation
You must run the binding compiler each time you recompile your Java classes or modify the binding definition, so it’s generally best to add the binding compiler step as part of your project’s standard build process. Performance was originally part of the inspiration for writing JiBX, and JiBX has consistently delivered performance far ahead of the field. Listing 14 shows a modified customization for the TimeCard schema that adds these attributes, with only the TimeCard element to be included in the generated data model along with everything used by the TimeCard representation, of course.
The JiBX documentation provides full details on all these customization options, along with more examples of schema generation from code. Once you’ve got a binding definition for your document format you’re ready to begin using JiBX.
JiBX: Binding XML to Java Code
Listing 2 shows some samples of the generated code, with excerpts from the org. This should create a dwcode2 subdirectory in the jibx directory, with the example files including build.
This change reduces the number of top-level classes in the data model from 15 to 10 — not a bad start on simplifying the data model. The codegen examples show how to use the code and binding generation from schema, both with and without customizations.
The big differences besides the simplified class Javadocs are that the Customer class is now inlined, and the Shipping class is now an inner documentztion using a custom typesafe enumeration class. Many other options can be passed to BindGen from the command line.
Listing 11 shows another awkward aspect of the generated data-model classes, in which a java. In this case, the decorator is a predefined one provided as part of the CodeGen distribution, which adds useful support methods for collection values. Fortunately, you don’t need to understand the binding definition in order to work with JiBX using CodeGen binding and code generation, so this tutorial doesn’t cover the details.
You documehtation also set the XML name for a value by using a customization specifically for that value. You can use a customization to change one of these names to something more meaningful. The package documentaion generated from the schema namespace, org.
Java code to XML schema
This content is part of the series: Subscribe me to comment notifications. Definition details Definition contexts. You can run the tool directly from the command line or indirectly via a build tool such as Apache Ant. The tutorial download includes an Ant build.
The custgen1 Ant target runs BindGen using the Listing 6 customizations. For most applications, this type of choice handling works well, preventing the user from trying to set more than one alternative in a choice.
If you install the sample code elsewhere, you can still use the Ant build. This dofumentation uses both item-name and element attributes. Dicumentation default, JiBX expects to have a no-argument default constructor defined for each class which the Java compiler generates automatically, if you don’t define any other constructors. You don’t need a detailed understanding of XML schema definitions, but some familiarity with schema will help you understand the examples better.
It unmarshals sample documents using the generated data-model classes and then marshals the documents back out and jlbx the result with the original document.
Wipe all files from target directory before generating output ignored if the target directory is the same as the current directory. Here’s a simple example just to give you a feeling for how this works: Listing 10 shows the test document:.
