Code generation for JiBX data binding converts operations defined by a Web service to method calls. The getBook operation takes a getBook element as input, and returns a getBookResponse element as output, while addBook takes an addBook element as input and returns an addBookResponse as output. Here's the body of the client interface generated by the standard JiBX code generation:. You can see that the JiBX code generation converted the operations into simple method call interfaces using objects corresponding to the input and output elements of the operation see JiBX Unwrapped Example for the interface generated when unwrapping is instead used. The server-side interface is the same. This must define concrete mappings for each element used as the input or output of an operation.

This document describes using JiBX data binding with Axis2. JiBX differs from the other data binding techniques supported by Axis2 in that it allows you to use your own Java data objects as opposed to Java data objects generated from a schema definition.
JiBX also provides a nicer form of unwrapped Web services interface than is supported by the other data binding techniques. On the downside, JiBX requires more setup than the other data binding techniques - in particular, you need to come up with a set of data classes and a binding definition in order to work with JiBX in Axis2.
JiBX uses a mapped binding approach that's based on binding definition documents you provide. This approach let's you customize the way your Java objects are converted to and from XML. You can even define multiple bindings to use the same Java objects with different XML representations.
These features make JiBX especially useful if you're developing a Web service based on existing Java code, or when you need to support multiple XML representations for a Web service as when you're using versioned schema definitions. Axis2 supports using JiBX with your Web services, including generating the necessary linkage code for both client and server sides. However, the Axis2 support for JiBX does not currently include code generation from the schema for a Web service - you need to provide your own data classes and JiBX binding definition, and you also need to make sure that the binding definition matches the XML structures defined for your Web service.
The JiBX project provides some basic tools to help with code generation from schema, binding generation from Java classes, and schema generation from the combination of Java classes and a binding definition.
In the future, improved versions of these tools will be integrated directly into the Axis2 framework support, but for now you're on your own with this part of the setup. You can use JiBX data binding both to expose existing Java code as a service, and to build a client for an existing service.
This document runs through the sequence of steps involved for each of these cases, just to help users understand the basic approach to working with JiBX in Axis2. Wrapped service definitions can be "unwrapped" during code generation to provide a greatly simplified interface.
JiBX unwrapping of service definitions is not compatible with the unwrapping support for other data binding frameworks used with Axis2, but most users will find the JiBX approach easy and convenient. If you use a wrapped interface for your Web service you can expose method calls in your existing code directly as operations in the service.
In this case you normally just use your existing data objects with JiBX data binding, and add schema definitions for the wrapper elements. If you use a non-wrapped interface for your Web service you need to define classes to hold the data input and output from each operation. In this case these holder classes need to be included in the JiBX binding definition. Here's the sequence of steps for using JiBX with Axis2 to implement a client for an existing Web service or the actual service, when you've been supplied with the WSDL your service is to implement :.
As with the starting from Java case, there are some differences in the handling depending on whether your service definition fits the wrapped form. If you want to use the unwrapped form of interface you also need to specify the -uw option to WSDL2Java. In this case your JiBX binding definition must include abstact mappings for all the complex objects which correspond to method parameters, and each abstract mapping must specify a type-name attribute that matches the schema complexType used in the WSDL.
You can also use formats in the binding definition to define the handling of schema simpleType s. Schema types corresponding to Java primitives and simple objects with built-in JiBX conversions are handled automatically, and if all the parameter and return values in your wrapped WSDL are of these types you don't even need a JiBX binding definition. If you're not unwrapping the interface, you must use a JiBX binding definition and it must include a concrete mapping for each element used as input or output by any operation.
These features will be integrated into the Axis2 JiBX support when they are available. JiBX: Bindings Tutorial. Last Published: Version: 1. Content Introduction Wrapped vs. Wrapped vs. Create a schema that matches the XML defined by your binding you may be able to use the JiBX schema generator to help with this.
If you're using a wrapped form of interface to your service you'll also need to create schema definitions for the wrapper input and output elements used by each operation. Create a WSDL document for your service, with the schema embedded or imported. Run the JiBX binding compiler on your Java classes to add the actual binding code.
Include the axis2-jibx. Starting from WSDL Here's the sequence of steps for using JiBX with Axis2 to implement a client for an existing Web service or the actual service, when you've been supplied with the WSDL your service is to implement : Create Java classes for the data being transferred by the Web service, and a JiBX binding definition that maps these classes to the schema defined by the Web service you may be able to use the JiBX xsd2jibx tool to help with this.
Finally, you need to have the axis2-jibx-XXXX.
JiBX general document/literal
XML schema to Java code
Improve schema quality with custom conversion of Java data models to and from XML documents. But the complexity of its binding definitions and its limited support for increasingly widely used XML schema definitions have frustrated users at times. Fortunately, the 1. In this tutorial, you'll learn about using the new features of JiBX 1. Part 2 covers the flip side of starting from XML schema definitions and generating Java code. You'll first see how to start with a simple Java data model and generate a default schema matching that model.
Java code to XML schema
To install JiBX, just download the distribution zip file and unpack it. This will create a jibx directory that contains the distribution files, including a complete copy of this documentation. The readme. There's also a Maven2 plugin available for JiBX.
JiBX: Getting Started with JiBX
Welcome to JiBX tutorial. It is very useful in applications integration where XML is the format for data transfer. JiBX performs these tasks via utility classes generated at compile time via ant scripts. This approach reduces the processing time by moving away from the traditional two-step process with other parsers to a single step. Benchmarks done on various XML binding tools have shown JiBX as the fastest and the most memory efficient parsing framework till date. Below image shows the final eclipse project that we will have after everything is set up properly.
