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.

Besides the PersonName components used as examples in the preceding subsection, the TimeCard schemas have a number of other complex components that are not used in the sample documents included in this tutorial. The Ant run1 target runs the test program using a data1. The PersonNameType consists of several jbx xs: Sosnoski Sosnoski Software Associates Ltd.

There are also convenient examples to help get you going, in four flavors: Listing 17 shows the same customizations as Listing 16restructured to use this alternative approach:. The distribution comes with all the core components of JiBX, including the binding compiler, runtime, extras, and various flavors of generation tools. Web service definitions are one of the main uses of XML schemas. Performance was originally part of the inspiration for writing JiBX, and JiBX has consistently delivered performance far ahead of the field.

The second customization is for the items collection property. These modifications to field names are applied before the fields are matched to value names used in other customizations and naturally also apply when XML names are generated from the field names.

XML names are not as standardized, and several different styles are commonly used. Besides determining how values are found from the class representation, the property-access setting also controls how the values are accessed by the generated JiBX code — directly from the fields or by calling the access methods.

Start from Code Start from Dcoumentation. The Address class is used in two places within the Order class for billing and shipping addresseswhich is why that class is represented by a separate global definition in the schema.

Listing 6 gives a simple example:. 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. The set methods for values included in the choice allow you to write a new value for the current selection but prevent changing the selection directly throwing an IllegalStateException if you try. It’s even possible to replace the default name conversion class with your own implementation, if you want to do something really special in the name conversions.


Sharp observers will notice one difference between the input and output that seems significant, in the item-list portion of the output document, shown uibx Listing View image at full size.

The first of these attributes defines the base namespace, while the second prevents the normal behavior of modifying the namespace based dockmentation the Java package. You can use tools included in the JiBX release to generate a schema definition matching your Java code or to generate Java code matching your schema definition. As with the includes attribute, you can precede names in the requireds and optionals lists by a flag character to indicate whether they should be expressed as a child element or an attribute.

To use JiBX, you’ll need to first create a binding definition that describes how your XML documents are connected to your Java objects. You can also control the XML representation of a value using the includes attribute.

Any configured code generation decorators are called in sequence by CodeGen as it constructs the source code for data model classes, and documnetation the opportunity to modify or add to the field, method, and class constructs generated by CodeGen.

Here’s the Java command line for duplicating the Ant codegen target from a console in the dwcode2 directory assuming you’ve followed the recommended installation instructions:. Listing 14 shows the resulting schema structure generated as starter.

JiBX: Getting Started

It represents more than corporate members, and almost 50 technology firms are certified to meet its standards. What sets JiBX apart from the others are performance and flexibility features.

You’ll first learn how to work with a simple schema and generate a default Java data model matching that schema, then use that data model for reading dockmentation writing XML documents.

If you don’t already have Ant installed on your system, you can documdntation it from the Ant Project page. 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. Listing 13 shows the result of applying the customizations. Start from Schema Start from Schema. Listing 10 shows the test document:. Subprojects Eclipse Plug-in Introduction. To learn more about using these and many other JiBX features check out the Binding Tutorial section of this site.

To change the current selection once it has been set, you first need to call a clear method here clearReportedResourceSelect which resets the selection state.


You’ll learn how in this section. Listing 11 shows another awkward aspect of the generated data-model classes, in which a java. Using an individual value customization gives you full control over both how that value will be accessed and how it will be represented in XML. 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.

One of the nicer BindGen features is that it can generate schema documentation from Javadocs in the input classes.

JiBX’s binding capabilities go far beyond what’s shown by this simple example. It also provides very high performance, outperforming all other Documeentation data binding tools across a wide variety of tests. Once you’ve got a binding definition for your document format you’re ready to begin using JiBX.

Docuentation the complexity of its binding definitions and its limited support for increasingly widely used XML schema definitions have frustrated users at times.

JiBX: Binding XML to Java Code

The enhanced class files generated by the binding compiler use this runtime component both for actually building objects from an XML input document called unmarshallingin data binding terms and for generating an XML output document from objects called marshalling. CodeGen supports extensive customizations for many aspects of code and binding generation.

Once the binding compiler has run and your classes have been enhanced with the JiBX binding code, you can continue the normal steps you take in assembling your application such as building jar files, etc. You’ll first see how to start with a simple Java data model and generate a default schema matching that model. The data-model code generated by CodeGen using default settings has some weaknesses.

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 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.
