 <h1>JiBX Integration With Axis2</h1>
 <p>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.</p>
 <p>JiBX support for Axis2 and Web services in general is continuing
 to evolve. This page covers the basics of using JiBX with Axis2 as
 of the current release. Check the <a href=
 "http://www.sosnoski.com/jibx-wiki/space/axis2-jibx">JiBX Axis2
 Wiki page</a> for updated information about using JiBX with
 Axis2.</p>

 <h2>Introduction</h2>
 <p><a href="http://www.jibx.org">JiBX data binding</a> supports
 fast and flexible conversions between plain old Java objects
 (POJOs) and XML. 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).</p>
 <p>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.</p>
 <p>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. You can find full instructions on the
 standard JiBX parts of this sequence on the <a href=
 "http://www.jibx.org">JiBX Web site</a>.</p>
 <a name="wrapped" id="wrapped"></a>
 <h2>Wrapped vs. unwrapped</h2>
 <p>Axis2 support for JiBX currently only works with the
 document-literal (doc/lit) form of Web services definitions.
 Doc/lit Web services generally use particular schema elements as
 input and output from each operation, and the Axis2 support for
 JiBX assumes this structure (which is also the structure required
 for compatibility with the <a href=
 "http://www.ws-i.org/Profiles/BasicProfile-1.1.html">WS-I Basic
 Profile</a>).</p>
 <p>A popular subset of doc/lit Web services use a form called
 "wrapped". Wrapped doc/lit Web services define service operations
 that correspond to method calls, using input and output element
 names based on the method name and embedding the actual parameter
 values for the method call within the input element.</p>
 <p>When used with Axis2, JiBX supports both general doc/lit and
 wrapped service definitions. 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. See the <a href="./jibx-unwrapped-example.html">JiBX
 Unwrapped Example</a> and the <a href=
 "./jibx-doclit-example.html">JiBX Document/Literal Example</a>
 pages for a detailed comparison of the two forms of service
 interface.</p>
 <a name="java" id="java"></a>
 <h2>Starting from Java</h2>
 <p>Here's the sequence of steps for using JiBX with Axis2 to expose
 existing Java code as a Web service:</p>
 <ol>
 <li>Create a JiBX binding definition for the data being transferred
 by the Web service (you may be able to use the JiBX binding
 generator to help with this step).</li>
 <li>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.</li>
 <li>Create a WSDL document for your service, with the schema
 embedded or imported.</li>
 <li>Generate Axis2 server-side linkage code using WSDL2Java with
 the WSDL and your binding definition.</li>
 <li>Run the JiBX binding compiler on your Java classes to add the
 actual binding code.</li>
 <li>Include the <i>axis2-jibx.jar</i> in your runtime classpath,
 along with the <i>jibx-runtime.jar</i>.</li>
 </ol>
 <p>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. See the <a href=
 "./jibx-unwrapped-example.html">JiBX Unwrapped Example</a> page for
 more details on how this works.</p>
 <p>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. See the <a href=
 "./jibx-doclit-example.html">JiBX Document/Literal Example</a> page
 for more details on this case.</p>
 <a name="wsdl" id="wsdl"></a>
 <h2>Starting from WSDL</h2>
 <p>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):</p>
 <ol>
 <li>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).</li>
 <li>Generate Axis2 client linkage code using WSDL2Java with the
 WSDL and your binding definition.</li>
 <li>Run the JiBX binding compiler on your Java classes to add the
 actual binding code.</li>
 <li>Include the <i>axis2-jibx.jar</i> in your runtime classpath,
 along with the <i>jibx-runtime.jar</i></li>
 </ol>
 <p>As with the starting from Java case, there are some differences
 in the handling depending on whether your service definition fits
 the wrapped form. See the <a href=
 "./jibx-unwrapped-example.html">JiBX Unwrapped Example</a> and
 <a href="./jibx-doclit-example.html">JiBX Document/Literal
 Example</a> pages for more details.</p>
 <a name="codegen" id="codegen"></a>
 <h2>WSDL2Java usage</h2>
 <p>To run the WSDL2Java tool for JiBX data binding you need:</p>
 <ol>
 <li>To specify <i>-d jibx</i> to select JiBX binding.</li>
 <li>You also generally need an additional parameter,
 <i>-Ebindingfile {file}</i> (where <i>{file}</i> is the file path
 to your JiBX binding definition).</li>
 <li>Finally, you need to have the <i>axis2-jibx-XXXX.jar</i>, the
 <i>jibx-bind-XXXX.jar</i>, and the <i>jibx-run-XXXX.jar</i> files
 from your Axis2 distribution included in the WSDL2Java
 classpath.</li>
 </ol>
 <p>If you want to use the unwrapped form of interface you also need
 to specify the <i>-uw</i> 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 <i>type-name</i> attribute that
 matches the schema <i>complexType</i> used in the WSDL. You can
 also use formats in the binding definition to define the handling
 of schema <i>simpleType</i>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. This is the one case where the <i>-Ebindingfile
 {file}</i> parameter is not needed.</p>
 <p>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.</p>
 <a name="coming" id="coming"></a>
 <h2>Coming Attractions</h2>
 <p>Work is in-progress on better tools to support generating Java
 classes and corresponding JiBX binding definitions from an input
 schema, and also for generating binding+schema generation from
 existing code. These features will be integrated into the Axis2
 JiBX support when they are available. Check the <a href=
 "http://www.jibx.org">JiBX project site</a> for updates on JiBX,
 and the <a href=

 Wiki page</a> for updated information about using JiBX with
 Axis2.</p>
