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.

As an example, I’ll start with the Java code for a set of bean-style private fields, public get and set access methods classes used to represent an order from an online store. Definition details Definition contexts.
JiBX: Getting Started
This gives a sample of the HR-XML schema style, which uses a mixture of nested and global type definitions and contains a wider range of schema structures than the first example, including:. Table 1 lists the most important options:. One part of the association is fixed, though: 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.
Listing 6 gives a simple example:. You can try out the Listing 12 customization using the custgen1 Ant target, or use the custom1 target to run the complete sequence of generate, compile, bind, and test. 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.
Default package for all schema definitions default is to use package generated from each schema namespace.
JiBX – Plugin Documentation
To do this, you first compile your application classes as normal, then run the JiBX Binding Compiler. BindGen tool included in the jibx-tools. BindGen Example Code Example 1.
The codegen examples show how to use the code and binding generation from schema, both with and without customizations. You can also run the entire sequence, from compiling the source docjmentation to running the test program, with the custom1 Ant target. Listing 17 shows the same customizations as Listing 16restructured to use this alternative approach:. In this section, you’ll learn how to customize BindGen operation to control the XML representation of data, change the style of names and namespaces, and control some aspects of schema structure.
This will provide some details of what’s new in the JiBX release, and also links to both the above examples and the offline version of this documentation, also included in the distribution. This is the most accurate representation eocumentation xs: Listing 13 shows the result of applying the customizations. You can use the custgen3 Ant target to try this customization with CodeGen, or documentatio the custom3 target to run the complete sequence of generate, compile, bind, and test.
Java names customarily use a “camelcase” style: If you install the sample code elsewhere, you can still use the Ant build. 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. You’ll see how to work with these value customization elements in a later example. This content is part of in the series: The XML Schema standard is complex, and tools for working with schema definitions provide little support for restructuring and refactoring schemas.
Finally, you need to list the root class es you want used for generation. Listing 6 shows excerpts of the generated code, which you can compare to the default generated code shown in Listing 2. You can try out these customizations by using the Ant custgen task instead of the codegen task or just use the full task, which runs the complete sequence of targets clean custgen compile bind run. You can easily define custom serialization handlers for data values, and you can tell JiBX to call your own methods at various points in the binding process to allow further customizations.
To install JiBX, just download the distribution zip file and unpack it. The item-name attribute controls the name used for the individual values represented by the collection, while the element attribute forces the use of the supplied name as a wrapper element around the values in the collection. The sample directory also contains a test program, org. If you’re starting from existing Java code you may find the Generator Tools subproject useful. If some of your classes only define constructors with arguments, you can use BindGen customizations to make them usable by JiBX.
You can use a customization to change one of these names to something more meaningful.
You’ll look into those later in the tutorial. 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.
Jibx2Wsdl builds on BindGen and supports all the same customization features for data model classes, along with some added customizations for the service class and WSDL usage.
In the GenderCode class, the BigInteger reference has been replaced with a simple int primitive type. For more details of using JiBX with existing XML schemas, including full details of the customizations structure, see the Start from Schema section of this documentation.
SerializableDecorator used to add the java. That binding definition is actually the main output of BindGen, with the schema generated from the binding. A customization file is passed to BindGen as a command-line parameter, using the form -c file-path. The set methods for values included in the jibd allow you to write a new value for the current selection but prevent changing the selection directly throwing an IllegalStateException if you dovumentation.
Most forms of code generation from schema generate a separate class for each complexType definition and for enumeration simpleType s. In the command-line samples I provided earlier see Generating the default binding and schemathe source path is supplied as -s src.
JiBX: Binding XML to Java Code
The package name generated from the schema namespace, org. The JiBX distribution includes an example starter project, with an Ant build. In the case of the TimeCard schema, there are a total of 10 global named complexType s and an additional 23 local anonymous complexType s, along with 8 enumeration simpleType s. 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.
XML names are not as standardized, and several different styles are commonly used. Instance creation during unmarshalling can also be controlled using customizations. The Ant run target executes this test program, using the Listing 3 document as input and writing the marshalled copy of the document to a file named out.
The download package also includes a simple test program, shown here as Listing 4that demonstrates using JiBX for both unmarshalling and marshalling documents. That’s not a significant issue for attributes which are always considered unordered in XMLbut it is important for elements.
