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.
You can see in Listing 10 that each of the references to a union type including both the TimeCardDuration type shown in the listing and the AnyDateTimeType is represented by a simple String value in the generated code. We’re not aware of any recent published performance comparisions between data binding frameworks, but you can view some older results from the BindMark tests, along with a similar study focused around Web services performance.
The schema uses only three global definitions: Of course, if you’re generating an output-only binding see the One-way conversions sidebarinstance creation is not an issue and you don’t need to be concerned about constructors.
Now download the tutorial sample codealso provided as a ZIP file. This target is an alternative to the bindgen target shown earlier, so to run the complete build you’d use the Ant command line: Here’s a simple example just to give you a feeling for how this works:.
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.
To use JiBX, you’ll need to first create a binding definition that describes how your XML documents are connected to your Java objects. Customizations can also be used to control some aspects of the actual schema structure.
Some aspects of the schema definition in Listing 9 are ignored or only partially handled by CodeGen. You can use the custgen3 Ant target to try this customization with CodeGen, or use the custom3 target to run the complete sequence of generate, compile, bind, and test.

JiBX: Getting Started with JiBX
Getting started To get started using JiBX, you just need to download the distribution zip file from the SourceForge downloads page and unzip it to a convenient location on your system.
How does JiBX manage to provide both flexibility and performance? This default handling converted the org. Right now, let’s look at the generated schema. Customizations Reference Extensions Reference. Wipe all files from target directory before generating output ignored if the target directory is the same as the current directory.
Basic use of JiBX 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: Working with a stand-alone schema definition is great for a simple demonstration, but it doesn’t give much of a feeling for how a tool functions when applied to the complex schema definitions widely used in enterprise applications.

JiBX: Getting Started with JiBX
In this case, you just need to edit the build. To get started using JiBX, you just need to download the distribution zip file from the SourceForge downloads page and unzip it to a convenient location on your system. Listing 7 shows an edited documenation of the main schema for the TimeCard element definition. You may want to assemble your class files into jar files, for instance, after docmentation run the binding compiler which currently requires the class files in un-jarred form.
Listing 11 gives a couple of examples of using customization elements for individual values, based on the same example code you’ve seen in the earlier examples:. To do this, you need to include jibx-tools.
The generated default data model consists of 15 top-level classes and 23 inner classes, just a few fewer than the number you’d expect to see based on the schema component counts.
If you compare Listing 12 with the Listing 10 sample, you’ll see how the representation has been 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 The JiBX documentation provides full details about different ways to run the binding compiler, including how you can invoke it when running your application rather than as part of the build.
You can also use a strip-prefixes attribute to remove unnecessary leading text from names, along with several other forms of customizations. 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.
Finally, you need to list the root class es you want used for generation. The Element object can be used to represent any arbitrary XML element including all attributes, namespace declarations, and contentso it provides all the flexibility needed to work with any document matching the schema definition. BindGen Example Code Example 1.
Serializable interface and optionally a version id to data model classes provide examples of working with the Eclipse AST to extend CodeGen, so the source code of these classes is a great starting point for writing your own decorators. This approach works fine for classes that represent simple data objects; however, if your classes include state information or computed values, you might end up with an XML representation that includes values you’d rather not expose outside the class.
It unmarshals sample documents using the generated data-model classes and then marshals the documents back out and compares the result with the original document. The binding compiler adds bytecode to your compiled class files that actually implements the conversions to and from XML, as specified by the binding definition.
There are also convenient examples to help get you going, in four flavors: Sosnoski Sosnoski Software Solutions, Inc.
JiBX , Part 1: Java code to XML schema
Binding Definition Binding Tutorial A basic binding. This count is exactly half the number of classes in the original data model generated without using customizations. Listing 14 shows jib resulting schema structure generated as starter.
By default, BindGen treats all primitive values and simple object values classes with direct XML equivalent types, other than String as attributes and treats all complex object values as child mibx. In the command-line samples I provided earlier see Generating the default binding and schemathe source path is supplied as -s src. The sample code includes an Apache Ant build file to automate running the JiBX tools and handle the other steps involved documnetation the examples.
BindGen supports extensive customizations for all aspects of binding and schema generation. This attribute is an example of an inherited customization setting, which applies to everything nested inside the element with the attribute. This won’t always be the case! 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:.
Definition details Definition contexts. If you have Ant installed on your system and have installed the download code according to the instructions, you should see output similar to that shown in Figure But the complexity of its binding definitions and its limited support for increasingly widely used XML schema definitions have frustrated users at times. You can see from Listing 7 that the description value is now missing from the schema representation, as specified by the customizations.
