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 also use a strip-prefixes attribute to remove unnecessary leading text from names, along with several other forms of customizations. XML names are not as standardized, and several different styles are commonly used. Listing 2 shows some samples of the generated code, with excerpts from the org. Customizations are always optional, and you never need to use a customization file unless you want to change the default BindGen behavior.
If you have Ant installed on your system and have installed the download code according to the instructions, you should see output similar to documentstion shown in Documentatoon 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 documenttation to represent an order from an online store.
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 CodeGen supports extensive customizations for many aspects of code and binding generation. These include the camelcase style with initial lowercase the Java field and property name stylecamelcase with an initial uppercase character the Java class name stylehyphen-separator words separated by hyphens style, dot-separator words separated by periods style, and underscore-separator words separated by underscores style.
That’s definitely the case here, where the actual values allowed for GenderCode are all single digits as shown by the original schema fragment at the bottom of the listing. You can even create your own custom marshalling and unmarshalling code that can selectively take over control from the code generated by JiBX to handle unique XML or Documenation data structures.
The customizations available include eliminating the component from the data model, changing the documentationn or value name used for the component, and changing the schema type of the component. Right now, let’s look at the generated schema.
This is the same test program as used in Part 1and it’s subject to the same limitations discussed in that tutorial.
When a new instance of the class is needed during unmarshalling, JiBX uses that no-argument constructor to create dkcumentation instance.
If you install the sample code elsewhere, you can still use the Ant build. CodeGen often is able to reduce the number of generated documwntation by examining references and inlining definitions where possible and by ignoring unused definitions in included and imported schema definitions. Here again, the code and binding generation uses default behaviors which will give a good data model for most schemas, but can be customized at every level to improve handling with features including: CodeGen by default generates a separate top-level class for every global type definition in the schemas specified as input, along with a corresponding abstract mapping in the generated JiBX binding for each complexType.
You can also use the require attribute to control which types should be treated as required values in the XML:. You may want to assemble your class files into jar files, for instance, after you’ve run the binding compiler which currently requires the class files in un-jarred form.
You can also set the XML name for a value by using a customization specifically for that value. It unmarshals sample documents using the generated data-model classes and then marshals the documents back out and compares the result with the original documenttion. Listing 18 shows the custom3. Performance was originally part of the inspiration for writing JiBX, and JiBX has consistently delivered performance far ahead of the field.
After reading this tutorial and working through the supplied examples, you will be able to documentafion JiBX to generate quality XML schema definitions from your own Java data-structure classes. 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.
Working with a stand-alone schema definition is great iibx 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.
If you don’t already have Ant installed on your system, you can get it from the Ant Project page.
The JiBX distribution includes an example starter project, with an Ant build. The big differences besides the simplified class Javadocs are that the Customer class is now inlined, and the Shipping class is now an inner class using a custom typesafe enumeration class. Start from code If you’re starting from existing Java code, you can use the BindGen tool included in the JiBX distribution to automatically generate a binding definition and corresponding XML schema definition from your code.
Example Code Default Generation. Nonsignificant parts of the document such as whitespace within a start or end tag, text between elements, and comments are lost when you unmarshal a document. For this tutorial’s purposes, you’ll keep things simple and just run the binding compiler through Ant. BigInteger is used to represent an xs: BindGen supports extensive customizations for all aspects of binding and schema generation.
Listing 11 shows another awkward aspect of the generated data-model classes, in which a java. You can use several different approaches for establishing the association between the customization and the schema element because one approach may be more convenient than another in a particular situation.
